Witcher: I Can Extract Everything

The Bloody Battlefield was a defensive war that took place in the west of the Wizard World. It would take place every 100 years.

Every 100 years, the magic array set up in the sealed land needed to clean up the accumulated negative energy particles. When it was lifted, the power of the seal would be weakened, and the Wraiths in the sealed land would explode, forming a tide of Wraiths.

If the Wraiths were not stopped from rushing out of the sealed land, they would threaten the entire West Coast.

And because of that, whenever the tide of Wraith erupted, the ruler of the West Coast, the Tower of Order, would summon the Wizards of the West Coast to the Bloody Battlefield to fight against the tide of Wraiths.

The entire period would be from three to five months to several years. During this period, the Wizards needed to block the onslaught of the Wraiths again and again.

Until the magic circle in the sealed land was restored.

...

In the sealed land, at the Bloody Fortress, another round of fortress defense battle had begun.

Wooooooo! The deep sound of a bugle horn resounded in the sky.

On the towering city wall, teams of warriors in bright armor walked up the city wall. Under the leadership of their respective commanders, they stood at the front line. Humans, Elves, Dwarves, Knights, and Wizards.

"Release the arrows!"

"Magic!"

All kinds of battle commands rang out around the battlements. One by one, basic commanders were waving their cross swords and shouting at the top of their lungs.

Along with their orders, arrows shot into the sky like rain. With the support of magic, they brought out all kinds of beams of light, like ribbons dancing in high control, and then slammed heavily into the ground.

Boom! Boom! Boom!

The sound of explosions could be heard continuously. All kinds of magic beams exploded under the city tower. Flames, frost, lightning, and all kinds of magic devoured and wreaked havoc in the army of Wraiths.

At the same time, the army of Wraiths also launched an attack.

Groups of Skeletons shot long bone spears into the sky. Under the full-force attacks of these pitchers, which were no less than Knights, the javelins easily climbed up the city tower that was hundreds of meters high and stabbed straight at the warriors on the battlements.

Although the commanders at all levels had ordered the heavy-shield warriors to defend at the first moment, they were still unable to deal with the swift and fierce javelins. There were frequent casualties.

First, an Elf was slow in evading and did not manage to hide behind the heavy shield. He was immediately pierced through the chest by the bone spears, the powerful impact sent the Elf flying back dozens of meters and nailed him to the battlements behind him.

Then, a few more shields were pierced by the bone spears, and the Dwarves' heads and chests exploded.

The cracked brains and blood splattered all over the ground, dyeing the city wall red.

"Roar!"

There was no time to accept this cruel scene, and a terrible roar had already sounded.

In the wilderness below the city wall, a few giant trees that were dozens of meters or nearly a hundred meters tall appeared. Their branches and leaves had completely withered, and there were a few holes on the trunk that made up their facial features, with dark green flames burning inside.

Forest Treant!

This was a species among the lower Treant species of the Forest race. Originally, the neutral race would not rashly launch an attack, but now, their bodies and souls had been completely eroded and polluted by the Wraiths.

The long branches that grew from the depths of the giant trees that came to the city tower rolled up the giant rocks on the ground and threw them toward the city tower.

These giant rocks that weighed thousands of kilograms were like light toys in front of the Forest Treants. They were easily thrown hundreds of meters into the air and smashed toward the city tower.

Buzz! Buzz!

At the same time, a sound that sounded like bees flapping their wings rang out. Many strange creatures flew out from the center of the Forest Treant's hollow trunk.

They were palm-sized little people, wearing clothes wrapped in tree bark and with sharp wings on their backs.

Forest Goblins.

They were also a member of the Forest clan and belonged to the Goblin species. They usually accompanied the Forest Treant and could release some simple spells. Their strength was about the same as an ordinary Apprentice.

Dozens or hundreds of Forest Treants flew up the battlements in groups, and they cast fireballs, ice arrows, and other kinds of spells at the warriors on the battlements.

Under the interference of the magic, there was a commotion in the front row. The archers could not dodge for a moment, the heavy shield soldiers could not hold the heavy shields in their hands. Gaps appeared in the originally solid defense line.

And what awaited them was the giant rocks and bone spears that flew up from behind. They were smashed into meat paste, nailed to the floor, and blood splattered everywhere!

"Magic! Give us the help of magic! Hurry up and chase away these damned fairies!"

The commanders tried their best to maintain the situation while shouting at the top of their lungs, seeking the help of the Wizards. Screams, commands, and howls of all kinds rang out continuously, and the entire battlements were in complete chaos.

On the side of the battlements.

Heath was carefully observing the battlefield ahead under the protection of a few personal guards.

In fact, after he was transferred to the Round Table Conference, his duty had also changed from a basic-level artillery station to a military staff officer. He was mainly engaged in strategic deployment and military planning, so there was no need for him to personally come to the frontline.

However, in line with the principle of his position, he still came up. After all, he really stood on the frontline and participated in the defense of the city, fighting side by side with other warriors, only then would he be able to understand what the warriors on the battlefield lacked, and the strategic deployment would be more accurate and effective.

In addition... he could also do some private research.

In any case, as a Wizard and Grand Knight, his own survival ability was still very high. He would not die so easily. Moreover, at the very least, he still had a substitute doll to take care of him?

"You guys wait here. I'll go up and take a look."

After saying this, Heath ignored the objections of his personal guards and walked straight to the battlefield on the frontline.

The silver-white Mimicry Shield pulled open the defense in front of Heath. The bone spear that seemed unstoppable hit it, but it did not move at all. The Forest Fairies next to him quickly discovered that he was an unusual creature, groups of them flew toward him and began to bombard him.

But similarly, Apprentice-level spells had quantity but no quality. It would take a long time to break through Heath's Mimicry Shield.

Heath then began to do his own research in peace.

He casually waved his hand, and the Wizard's Hand grabbed out. A Forest Goblin was pulled back by a strong suction force and flew into his hand.

Heath looked down at the little monster.

Forest Goblins were a relatively rare magical creature, and they had a certain amount of intelligence that could help a Wizard complete some magic tasks. Therefore, many Wizards liked to keep them as companions, in particular, Forest Goblins with outstanding innate talent had always been the favorite of the world of companions, worth millions.

Unfortunately, these Forest Goblins had already been contaminated, and their souls had been completely eroded. Now, they could only grimace at Heath and try to struggle and attack. It was impossible for them to become companions anymore.

Holding the Forest Goblin, Heath began his own research. He wanted to see if he could extract the Wraiths' negative energy.

These Wraiths were also magical creatures and extraordinary beings. In theory, they could be extracted after death. If the experiment was successful... Just look at the dense army of ants outside. One could imagine how exciting it would be...

Of course, it was not that easy to deal with them in practice.

If one wanted to extract them, they had to keep the completed body. However, the Wraiths had a level 3 undead characteristic. This level of undead power had already corroded every cell.

Normally, when dealing with Wraiths, there were two ways to deal with them. One was to destroy the physical body completely, or the other was to use purification, directly targeting the Wraith in the body.

However, once the Wraith was purified, its self-protection mechanism would form a backlash and burn the main body.

Without the completed corpse, there was naturally no way to extract it.

'Let's try purification first.'

Thinking to himself, Heath cast [Purification] on the Forest Goblin. This was a very basic Apprentice spell, positive energy type, no attributes.

The moderate and peaceful purification power surged into the Forest Goblin's body and began to clear the Wraith in its body. However, at the same time, the Wraith also began to counterattack on the verge of death.

Sizzle sizzle...

A series of crisp sizzling sounds could be heard as white smoke rose from the surface of the Forest Goblin's body. Then, with a 'bang' sound, it directly burned into a ball of white flames. In an instant, the Forest Goblin was extinguished in the flames.

"As expected, it didn't work..."

"Then what if I first drive the Wraiths to a certain part?"

While he was thinking, Heath casually grabbed another Forest Goblin. This time, he did not directly purify it. Instead, he first extended his spiritual tentacles into the Forest Goblin's body and drove away the Wraiths in the Forest Goblin's body.

This time, it worked very well. Through his spiritual power, Heath successfully gathered all the Wraiths in the Forest Goblin's body onto one of its arms.

He then cut off the arm and immediately purified it.

The arm burst into flames, but the Forest Goblin's corpse remained intact.

"Haha, success!"

Heath immediately said to the Forest Goblin in his hand, 'Extract!'

[Beep, extraction successful. Spiritual Power +0.06]

[Beep, extraction successful. Obtained [Forest Goblin's Life Sequence].]

[Beep, extraction successful. Obtained Talent [Fireball].]

[Beep, extraction successful. Fire Law +1]

Pure spiritual energy and strange information surged into Heath's mind, including the life sequence of the Forest Goblins, the talent spell of the Forest Goblins, and even the law power of the fire element!

'The upgraded system is indeed extraordinary!'

Heath was overjoyed.

Heath, who had tasted the sweetness, immediately increased his strength. While constantly capturing and purifying the Forest Goblins, he also constantly tried to improve his purification method.

With his help, the pressure on the battlements was indirectly alleviated. As he killed the Forest Goblins one by one, the warriors who no longer had to deal with these small monsters could once again raise their shields to defend and avoid attacks.

...

The war continued. The Wraiths would attack the fortress every now and then. At this time, Heath would also stand at the frontline to help defend the city while waiting for an opportunity to extract.

With this endless supply of targets to extract, his strength was also improving rapidly with each passing day.
