Interstellar Soldier

Chapter 166 Heading to the Center of the Earth
"It's near here. Let's search separately."

With Yang Yi's order, except for Lin Feng, everyone scattered in groups of two to search.

Although it is impossible to be sure that the enemy is drilling the hole here, there is a very obvious heat source here in the photos taken by the "Shadow", and according to Allen's analysis, such a huge heat source can only be emitted when the earth dragon is used to drill the hole. of heat.If it's just to create an ambient temperature suitable for the survival of Silicon Charm Warriors, an ordinary heat source is enough.The point is, drilling a tunnel to the center of the Earth would have to melt rock, which would generate a lot of heat.

Not long after, Jackson made a discovery.

It was indeed a tunnel, slanting downwards, with a diameter of more than ten meters.If it is a masterpiece of an earth dragon, then this earth dragon must be astonishingly large.

When Yang Yi and Lin Feng arrived, Jackson was analyzing rock samples with a portable instrument.

"How about it?"

"That's right, it's Dilong." Jackson handed the instrument to Yang Yi. "Gene samples of earth dragons were detected, as well as more than a dozen other silicon-based life forms."

"Follow the plan and be careful."

Jackson nodded, called Justin, and went ahead to open the way.

At this time, the chaos in the canyon has been brought under control.

Dozens of warriors were dispatched at the same time. Although the enemy who launched the attack was not found, the situation was stabilized.The dozens of camps that were attacked were all abandoned, and the living silicon demon fighters in these camps were transferred to nearby camps, while the dead silicon demon fighters were ignored.Several powerful warriors joined forces to remove the falling rocks blocking the middle of the canyon and connect the camps inside the canyon.

After Yang Yi and others entered the tunnel, Buck, who was in charge of breaking the rear, got in and installed a powerful original mine at the entrance of the tunnel.

The attack was proposed by Yang Yi, but others added.

According to the arrangement, after finding the tunnel, Yang Yi and Lin Feng led the officers and soldiers of the special squadron, that is, Jackson and others, into the tunnel to find and kill the dragon to prevent the enemy from advancing towards the center of the earth.Shen Chengwen led the officers and soldiers of the strategic squadron to follow Karl back to the Polaris base to deal with possible attacks by the enemy.According to Yang Yi's speculation, after the camp was attacked, the enemy might become angry.If the enemy commander was a little smarter, he could also think that the garrison had received reinforcements and launch a general attack in advance.Obviously, the garrison couldn't defend the Polaris base at all. If the base was captured by the enemy, even if Yang Yi and the others killed Dilong, it would be useless.

Although Shen Chengwen felt that Yang Yi's arrangement was not safe, after all, no one knew what the enemy was doing underground, and the team that followed Yang Yi into the underground was not considered strong, at least in Shen Chengwen's opinion, it was not the strongest combination. Insisting on this deployment, and with Lin Feng's support, Shen Chengwen couldn't object. After all, Lin Feng was the captain of the team, and Jackson was a real leader.

With Jackson around, even if he meets a few generals, the problem won't be too big.

Of course, how to escape from the ground is not a problem at all.

Don't forget, in Yang Yi's team, the weakest is also the fifth-level fighters. With their combat power, it is not difficult to forcibly open a passage to the ground.In addition, there are "Fire Phoenix" and "Frost Snow Tiger". As long as these two fighters are used, it is not difficult to make a hole in Prometheus, so there is no need to worry about retreating. .

Not long after, Buck caught up with the large army.

After entering the tunnel, everyone didn't hold back any more, and they all showed their strength as soldiers, and a few of the weaker ones even used the individual aircraft they brought.

In fact, the tunnel has an inclination of about [-] degrees, and it can fall down by gravity.

After a while, there was a low explosion sound from behind.

Yang Yi looked back at Buck, but said nothing.

It was the original energy mine that Buck installed at the entrance of the tunnel that exploded, and it was very violent, but he couldn't feel it because he was far away.

The power of the original mine is very powerful, enough to blow up the entrance of the tunnel.

Although it can't stop the strong fighters of the general level, it can cause some troubles for the enemy, making the enemy have scruples and dare not rush to catch up.

Yang Yi didn't know how long this tunnel was.

After traveling for about half an hour, the tunnel suddenly turned and went straight down.

Seeing the mark left by Jackson, Yang Yi accelerated his speed.More than ten minutes later, Yang Yi and others met Justin who stayed behind to meet him.

Ahead, there are more than ten passages.

Jackson has entered a passage and has not yet returned.

"Search separately, and return immediately after finding the situation. If you don't find the situation, gather here after half an hour. If you encounter the enemy, don't fight recklessly. Before we figure out the situation, we can't act rashly." People assign tasks.

It's not clear how far down the line, but Carl's fears have been borne out.

The army of silicon charms dispatched the earth dragon, trying to drill a tunnel leading to the center of the earth.There is no doubt that the enemy's goal is to completely control the Prometheus star.According to Karl, if the enemy reaches the center of the earth, they can kill all human soldiers on Prometheus by changing the gravitational field, and even completely change the environment of Prometheus.If it is not stopped, the human legion will lose this important planet forever.

As for what would happen next, Karl didn't say, and there was no need to say so.

If the environment of Prometheus is not suitable for human soldiers to garrison, or even allow human beings to survive, the only option for the first war zone is to completely destroy Prometheus, which is better than letting it fall into the hands of the Silicon Demon Alliance and become a Silicon Demon. The springboard for the Grand Army's invasion of the Southern Alpha system is much better.

If we really want to get to this point, everyone on Prometheus will end badly.

To put it bluntly, as long as Marshal Sean makes the decision to destroy Prometheus, no one will care about the defenders here, nor will they send troops to rescue them.

Thirty thousand soldiers are just a fraction.

During the Fifth Greenwich War, the Human Federation armed tens of billions of officers and soldiers. At the beginning of the war, when the situation was extremely unfavorable to the Federation, they voluntarily abandoned many colonial planets and the troops stationed on these planets.For the final victory, no commander will pay attention to the life and death of a few soldiers.In fact, even Xiao Wentian gave up many subordinates in the offensive and defensive battle of Lighthouse Star.

After half an hour, everyone rushed back.

However, Jackson still did not come back.

Yang Yi didn't delay much, and immediately led the team into the passage that Jackson was investigating.

This time, it was Justin who opened the way ahead.Obviously, Jackson found the right direction and encountered trouble, otherwise he would have rushed back.

After traveling along this straight passage for about half an hour, the temperature began to rise.

This is not a good sign.

Although the geological activities of Prometheus are very frequent, as early as a thousand years ago, the first theater tried to transform this planet.Since then, a tunnel to the center of the earth that runs through the north and south poles has been opened.Because it was originally planned to install an SSS-level original energy converter in the center of the earth, when the tunnel was opened, the engineering troops in the first theater cooled the core of the earth, and the Prometheus star lost its geomagnetic field. .

Simply put, the core of Prometheus star has cooled down long ago, and it is only the liquid mantle that causes geological activity.

Yang Yi and the others have been marching for more than an hour, and at their speed, they have already passed through the mantle.It stands to reason that the ambient temperature should tend to stabilize rather than increase abruptly.

The only thing that can cause the ambient temperature to rise is a high-temperature object.

Silicon Beast!

A huge dragon!

You should know that the earth dragon is the largest among the common silicon beasts. There is no upper limit to the weight of an adult earth dragon. As long as there is a suitable environment and growth-promoting nutrients, the earth dragon can continue to grow.In the records of the Human Federation, an earth dragon with a size equivalent to an asteroid once appeared.In fact, this is not the largest earth dragon yet.It is rumored that in the Northern Alpha galaxy, some earth dragons that have survived for hundreds of thousands of years can grow to the size of a giant planet and rule a star system. It is itself a huge ecosystem and becomes the home of other silicon beasts.Of course, this kind of super earth dragon is also a threat to the intelligent civilization of the Silicon Magic Alliance, so it is extremely rare.

In addition, the earth dragon itself is a commonly used "weapon" of the Silicon Magic Alliance.

In the past several Greenwich Wars, the Silicon Charm Alliance often used earth dragons to control planets and carry out environmental modification on already occupied planets.

However, the domesticated and controllable earth dragons are not very big, at least not comparable to the rumored super earth dragons.

Justin was so anxious that he increased his speed to the limit in one breath.

Yang Yi and Lin Feng didn't dare to hesitate, and immediately accelerated to catch up.Fortunately, Justin is only a tenth-level soldier, and the limit speed he can reach is not much faster than Lin Feng, who is also a tenth-level soldier.Yang Yi possesses the "source of life", and his limit flying speed is not lower than that of a tenth-level soldier.

It's just that other people can't keep up.

After flying for more than ten minutes, a dazzling light shot from the front.

Seeing Justin ahead, Yang Yi and Lin Feng immediately slowed down.

At this time, Yang Yi discovered that the ambient temperature had already reached thousands of degrees Celsius, and even with the protection of an energy barrier, he could still feel the scorching heat.

Lin Feng slightly nodded towards Yang Yi, telling Yang Yi not to worry.She has already contacted Buck and others to let them stay behind.

In addition, the gravity is very weak, indicating that it is already inside the core of the earth.

The bright light comes from the exit of the tunnel.

If the information provided by Karl is correct, the core of the earth is hollowed out ahead.Obviously, that crimson light is not a natural product.

The enemy has tunneled through and reached the center of the earth!

"Ow—"

Hearing the roar coming from the front, Yang Yi took a deep breath.

Strictly speaking, that is not a roar, but the sound made by the earth dragon when it devours the rock and discharges the high-temperature gas produced when the rock melts.

The enemy has already occupied the center of the earth, can Prometheus still hold on?
