My monster merges everything.

Chapter 409 Breakthrough
The Demon Mother's Nest began to fuse one third of the bodies of the Lunar Eclipse Worms. Although it was not much, the Zerg's inferior materials were the most abundant thing on this battlefield.

While Su Han ordered the Demon Mother's Nest to merge, after recovering a little, he ordered the Void Giant Demon to bring the bodies of the two killed insect demons back to the defense line.

The battle lasted all night, and the attacking and defending soldiers had been replaced several times.

With the vacuum period caused by the killing of high-level Zerg, the Zerg's offensive weakened greatly. Under the coverage of artillery, it was impossible to climb over the mountain walls. A large number of Zerg corpses piled up on the battlefield, and were constantly devoured by the Four Moon Nests, and then transformed into third- and fourth-level Apostle Zerg to join the battlefield.

Not only the Moon Nest, but also the insect nests in the four cities that were previously constructed by a large number of mother tank insects also benefited from the large supply of insect swarm corpses, transforming a large amount of insect matter into breeding first and second order low-level insect swarms.

Although the number is far less than the hundreds of millions of swarms prepared by the Abyss Zerg, they are also playing a corresponding role in conjunction with artillery strikes and high-level swarm raids.

Break into the battlefield to block, suicidal entanglement, and take advantage of the gap to plunder the corpses of high-level insect swarms
There is no shortage of them on the battlefield, and as they continue to hatch, their numbers are gradually increasing, greatly reducing the defensive pressure on human soldiers.

The large number of Zerg corpses not only provide nourishment for the Zerg nest to breed a large number of apostle Zerg, but also serve as nutrients for the colonized heavenly soldiers.

Shu Hongguang and Gao Mingwei's Colonial Heavenly Soldiers Factory built a large-scale culture tank similar to a bug nest, which continuously bred second- and third-order Colonial Heavenly Soldiers to join the battlefield.

A portion of the colonial heavenly soldiers are controlled by warriors and are specifically responsible for blocking the swarms of insects that want to climb over the city walls.

With their flexible bodies and fierce attacks, the existence of the colonial mechas themselves makes them not afraid of ordinary pain. Therefore, when fighting against the swarms of insects that have climbed over the city walls, the soldiers who control the colonial mechas basically attack with the most fierce and direct means, not hesitating to exchange injuries for injuries, in order to prevent the swarms of insects from destroying the defensive positions.

Another part of the Colonial Sky Soldiers are directly controlled through the Star Torch network. Although they are not as flexible as the Colonial Sky Soldiers controlled by warriors, their fearlessness and bravery make them a spearhead force on the battlefield after the Apostle Zerg.

Sometimes, their bodies are loaded with killing weapons such as nuclear bombs and sub-nuclear psychic bombs. Under the cover of the team, they go straight to the densest area of ​​the insect swarm, or go straight to the insect bridge and destroy it directly.

The swarm of insects began to split up, and a large number of them moved towards Linghai City and Hangbang City. They seemed to want to bypass the tough nut of Guanhai City and find a way to break through the mountain defense line.

"At least 30 million insect swarms are moving towards Linghai City. There are no less than a hundred fourth-level insect beasts and three fifth-level insect beasts. Commander Zhu Xiong has been notified to prepare."

Liu Rulong's face was full of fatigue. The Zerg attack had lasted for two days and one night, and it had finally slowed down a bit, but the remaining three cities would have to bear more pressure.

"No trace of the sixth-level insect demon has been found yet. It may be that we cannot detect it."

He looked at Su Han who was sitting opposite him, reporting the situation on the battlefield, and asked in a deep voice: "That seventh-order eclipse worm."

"It is more seriously injured than me. It dares not leave the deep sea in a short time, otherwise it will be suppressed even more. But it is level six."

Su Han's face was serious, and he said, "Two sixth-level insect demons escaped, but that's definitely not all of their forces. They may have divided their forces to follow. I will send the apostle over."

Being injured by the seventh-order rule power, even Su Han's apostle would not be able to recover easily at this time. His condition might be slightly better than that of the seventh-order eclipse worm whose body was cut into one-third.

At the moment, Su Han also did not dare to leave the mountain wall and rush into the deep sea to look for trouble with the sixth-level insect demons or even the lunar eclipse worms. The same principle applies to the lunar eclipse worms.

Stay away from the Torch Tree position and go deep into the Eclipse Worm's territory, and it will be difficult to escape then.

You have to wait, wait for an opportunity to take action.

After the two men finished their discussion, Su Han dispatched his apostles out. The Black Turtle Ancestral Tree guarded Guanhai City, and the Void Giant Monster was sent by Su Han to Linghai City to guard the pass together with Zhu Xiong.

The Black Gold King went to Hangbang City, and the Dead Ice Bone King went to Jinsha City.

"It is not enough to only achieve a breakthrough in the Demon Mother's Nest. We must also allow the other apostles to break through."

As soon as Liu Rulong left, Su Han made a decision in his mind. The apostles he sent out needed to keep an eye on the sixth-order insect demons that might appear at any time, so he could not make too many moves at once.

However, the two apostles who stayed by his side were able to find a way to merge and upgrade.

"Leave the insect demon to the Demon Mother's Nest. The fifth-level insect beast is not suitable, so fuse it with water and soil. The Blood Prison Dragon King is compatible with water, and the Black Turtle Ancestor Tree is fused from the Blood Tree and Rock Turtle. It is more compatible with rock and soil, so we can continue to fuse it."

With him guarding Guanhai City, he can deal with it even if a sixth-level insect demon suddenly appears, so the two apostles can free up their hands.

With determination in his heart, Su Han let the two apostles start to act on their own.

The vines of the Black Turtle Ancestral Tree penetrated deep into the battlefield, constantly devouring the rocks and soil everywhere, and quietly changing the terrain in preparation for building a more favorable defensive terrain.

The Blood Hell Dragon King uses the sea inlet to directly merge the water body, intercepting the upstream water and at the same time causing seawater to flow back and be continuously merged by it.

Water and earth are not as powerful as sixth-order monsters. If you want to complete the fusion and improve their strength, the number required is an astronomical number.

While Su Han was guarding, he climbed up the mountain wall and activated his soul fusion talent. The Great Demon Space was now looming and overlapping with reality, constantly absorbing the emotional power and spiritual energy from the entire battlefield.
The battlefield is a nutrient factory for high-level psychic creatures. Although Su Han is a human, as his strength and level increase, he is, to some extent, a high-level psychic creature.

On such a battlefield, the emotional power, spiritual power, soul and other things that are nurtured are all excellent nutrients.

He could feel that the energy in his body was constantly increasing and accumulating more and more.

On the third day, one-third of the eclipse worms had completed fusion, and the fusion progress of the eclipse worms was 26%. The proportion was not high, but this was within Su Han's expectations.

The Blood Prison Dragon King LV7 has 12% water. Even after hundreds of thousands of tons of water were fused, it only barely reached this number.

The Black Turtle Ancestral Tree was slightly better, with LV7 rock and soil at 14%. It also eroded a large amount of rock, and many cracks quietly appeared on the ground, causing seawater to flow back, making it more difficult for the insect swarm to march.

On the fifth day, the insect demons raided Linghai City. There was one insect demon and four fifth-order insect beasts. The giant void monster controlled the void to intercept the attack. A fierce battle ensued, severely damaging a fifth-order insect beast. However, it was unable to stop the insect demons from escaping into the sea.

They were cautious in chasing him and did not dare to chase and kill him.

The swarm of insects is still testing, trying to find the weak points in the defense line bit by bit.

On the sixth day, Hangbang City came under attack. A swarm of insects larger than normal launched a surprise attack, impacting the mountain wall without any regard for losses.

Even if nuclear bombs covered the ground, the blazing flames of incendiary bombs could not stop their impact.

The Moon Nest hatched two black-armored war bugs and one abnormal tank bug, which directly joined the cleanup battle and barely resisted the siege.

At this moment, the insect demon suddenly appeared and launched an attack directly on the mountain wall.

The blatant attack even broke one-third of the mountain wall. The Black Gold Juntan resisted violently, severely injured the insect demon and repelled it, and killed three of the Void Giant Worms. When he was about to kill the insect demon, the space was disturbed and the insect demon escaped. He could only be seriously injured with one sword. The spatial fluctuation was the work of the Eclipse Worm. Although it had been severely injured and was recovering, it was obvious that it still had some tricks.

On the same day, the Demon Mother's Nest completed the fusion of a bug demon, and the fusion progress of the Eclipse Bug increased to 45%.

Blood Prison Dragon King LV Water 32%, Black Turtle Ancestral Tree LV7 Rock and Soil 42%, the progress of both is gradually increasing.

The ninth day, the tenth day, the fifteenth day.
The probing battles continued, and the insect demons' occasional surprise attacks made it difficult to catch them and keep them in check. The Eclipse Worm's interference became more and more obvious, and its injuries were recovering.

And it was obvious that he was looking for Su Han's whereabouts and checking Su Han's status.

The Zerg's offensive finally became more moderate. After half a month of attack, even though they had bred hundreds of millions of Abyss Zerg in the ocean before, after such a long period of consumption, the entire defense line had killed no less than 100 million Zerg.

Even if a large portion of the Zerg corpses are recycled by the Abyss Zerg, their consumption is far greater than what they gain.

Apart from the monsters and organic matter in the wild, psychic energy, and the emotions and spiritual power overflowing on the battlefield, they have no way of obtaining too many resources.

As a result, the swarm will naturally slow down its pace as its income is insufficient to cover its expenditure, and part of it will spread to areas outside the target southern territory.

The Red Bears detected their movements, but they could not spare the extra energy to stop them.

Finally, on the sixteenth day, the Demon Mother's Nest completed its fusion.

[100% fusion of Eclipse Worms, Demon Mother's Nest advanced to the sixth intermediate level, obtained skill advancement: LV4 Worm Eye, LV2 Moon Nest, LV2 Domination Will]

After half a month of fusion, the Demon Mother's Nest finally completely digested the body of the Moon Eclipse Worm. Although it was not the entire body, the rest relied on the corpses of two sixth-level insect demons and tens of millions of abyss insects, which was converted into 100%.

But when the breakthrough comes, it's all worth it.

A powerful aura rose from its body, spiritual energy surged, and the power of rules continued to emerge around it and merge into its body.

This powerful aura not only reached the middle level of the sixth order, but also pushed its strength forward a few points, already approaching the upper level of the sixth order.

Su Han absorbed the feedback power from the Demon Mother's Nest. Under the flushing of spiritual energy, his body and spirit were one step closer to the upper sixth level.

"The spiritual strength of the LV4 Insect Eye is even higher. The hallucinogenic effect is not only limited to hallucinations, but also has a little power to distort the rules of truth and falsehood. This is the power of the Eclipse Moon."

Su Han sensed the change in power, his eyes moving slightly. He still remembered the twisted and corrosive force field of Eclipse Moon. Every twist made the attack more powerless.

The Insect Eye has gained similar abilities, and even though there is some difference, the enhanced power should not be underestimated.

In addition, the Moon's Nest and the Dominant's Will have been strengthened, which has made the overall strength of the Demon Mother's Nest even more terrifying.

"First wait for the Blood Prison Dragon King and the Black Turtle Ancestral Tree to break through."

Su Han suppressed some of the thoughts in his mind and took a look at the Demon Mother's Nest and the large number of insect corpses piled up in the insect nest.

Under his control, the Demon Mother's Nest immediately devoured the corpses. It continued to transform them and then injected a large amount of spiritual energy and rules into them.

An hour later, three moon nests that looked like flesh and blood moons suddenly appeared in front of the Demon Mother's Nest.

The LV2 Moon Nest has a higher upper limit, and the monsters it breeds will be more powerful.

Su Han did not hang the Moon Nest directly above the four cities. This time he wanted to hide part of his power and accumulate more power.

The three-month nest was placed outside the East China Sea base. The logistics troops and the engineer bugs of the Apostle Zerg would transport back a large amount of flesh and blood for them to devour.

During these three months, the nest will only breed fourth- and fifth-level insect beasts to support the battle on the front line.

With the addition of the Three Months' Nest, not many people noticed its impact on the front line, but as time went on, the number of fourth-order insect beasts appearing on the front battlefield slowly increased, making the defense line more stable.

A few more days passed like this, and finally, after integrating countless rocks, soils, and water flows, the Black Turtle Ancestral Tree and the Blood Prison Dragon King completed breakthroughs one after another.

[LV8 rock and soil fusion completed, Black Turtle Ancestral Tree breaks through the sixth level, obtains skill advancement: LV4 Earth Vein, LV2 Rock Sealed Crystal Shield, obtains new skill: LV1 Earth Vein Shield]

The aura of the Black Turtle Ancestral Tree's breakthrough was not obvious. It was like the steady and heavy aura of a mountain that quietly spread to every part of the land along with the veins of the earth.

Through the Black Turtle Ancestral Tree, Su Han could clearly feel the inseparable connection between the Black Turtle Ancestral Tree and the earth, as if every time he waved the roots and mobilized the vines, he could draw in more power from the earth.

"The Earth Vein Shield, a super strong shield built by drawing power from the earth and relying on the golden tree roots. Is the degree of defense determined by the earth veins?"

A look of surprise flashed across Su Han's eyes. This Earth Vein Shield was completely different from the Rock Sealed Crystal Shield. It was not relying on the power of the Black Turtle Ancestral Tree itself, but on the power of the earth veins.

If the entire earth vein can be mobilized, the shield power that is condensed will not just be level five or six.

A vein of the earth, or even several veins connected together, pass through countless mountains and hills. The strength of this power gathered together can be imagined.

"It can serve as a backup for the defense line. Now even the insect demons won't be able to easily destroy the defense line."

The protection of the underground veins can make the defense line safer as a whole. At least the attacks on the defense line by forces beyond the specified level will be curbed.

Although the constant attacks of the Zerg are equally terrifying, humans' weapons and resilience do not frighten them.

[Fusion of LV8 water completed, Blood Prison Dragon King breaks through the sixth level, obtains skill advancement: LV3 Black Water Vortex Cannon, LV6 Black Water Shield, LV7 Water Flow Control, obtains skill: LV1 Ocean Guardian]

The Blood Hell Dragon King completed the breakthrough, and was surrounded by countless rapids. Sometimes the water flowed like the roar of beasts, and sometimes it was like sharp blades. The momentum was much greater than that of the Black Turtle Ancestral Tree. Countless water flows now followed its movements like subjects.

A powerful feedback force surged into Su Han's body, and his aura leaked out like a cracked kettle. It was a natural breakthrough.

With the endless power attacks on the battlefield, the continuous gathering of human faith in the Torch Tree, and the three apostles completing breakthroughs one after another, Su Han also completed a breakthrough and reached the upper level of the sixth level.
