The second Zerg was slower because Tang Yu had cut off a leg in advance, and when it finally came over, Tang Yu had already killed the first Zerg with the power of thunder.

The death of the same kind did not make the Zerg under the wisdom retreat, its body shook, and it shook off the corpses of the same kind that was pressed on its body, and it was about to rush towards Tang Yu.

But what was waiting for it was a big knife stained with insect blood.

The sharp broadsword slashed straight down, pointing straight at the head of the zerg.

Formerly an armed policeman, Tang Yu naturally has a good sense of combat. Know to seize the opportunity and beat the water dogs.

When he kicked the first Zerg away and smashed it on the second Zerg accurately, restricting its movements, he had already rushed forward with a big knife without hesitation.

When the second Zerg shook off the corpse of the first Zerg that was pressing on his body, Tang Yu quickly seized the gap that paused after this action, and slashed it mercilessly.

There was a crisp cracking sound of bones.

Not surprisingly, the second Zerg followed in the footsteps of the first.

Tang Yu held the big knife and pulled it back, pulled out the blade embedded in the Zerg skull, and then put it in front of his eyes to look at it.

I have to say that this broadsword is really of good quality.

Because, the skulls of the Zerg are notoriously hard. Not to mention knives, even ordinary guns can't be easily penetrated.

And this big knife can do it. And after breaking the skulls of the two Zerg one after another, the blade did not even leave a single gap, which is enough to see that the quality is indeed extraordinary.

After eliminating the two Zerg, Tang Yu turned to look at the young man.

He is still fighting the two zergs, and the battle is not over yet.

Tang Yu didn't rush forward to help, but stayed where he was and watched.

Previously, he was hiding behind the door and looking at the young man through the cat's eyes. The distance is long, and the line of sight is also limited, so it is not very clear to see.

Now that he looked closely, he could see it clearly, and it didn't take long for him to spot the anomaly.

He found that this young man clearly had many opportunities to seize the loopholes of the Zerg's attacks, severely damage or even kill them, but he did not do this, but chose to keep leaving scars on the Zerg's body that were not serious or light, as if he was deliberately delaying......

Procrastinate?

Tang Yu frowned, looking at the figure of the young man, he was puzzled, obviously he didn't understand what his purpose was in doing this?

Looking at the dazzling long sword dancing, could it be that he was using these two Zerg to hone his swordsmanship?

Thinking of this possibility, Tang Yu's body shook and suddenly came to his senses.

This is the only possibility that can explain why he delayed and only injured and did not kill these two zergs.

Tang Yu glanced at this young man deeply, and he felt more and more that this person was not simple!

At such an age, he made a tricky swordsmanship. In the face of the Zerg, not only is he not panicked, but he is also in the mood to practice the sword with the other party, which is not something that ordinary people can do.

When Tang Yu thought like this in his heart, the only two remaining Zerg were finally under the long sword in the young man's hand, and they were covered in bruises, lost too much blood, and became unable to stand up.

The Zerg in this state obviously can't play the role of honing swordsmanship, so he didn't delay any longer, his eyes were cold, and he flew out and stabbed a sword.

The timing of his sword was good, just to catch the gap in the pause of the Zerg's body after the movement.

I saw a little cold light flickering, and the tip of the sword easily pierced the skull of the zerg, an inch into the bone.

The first Zerg is dead!

The young man then turned to the left side, and then used his heel to exert force, jumping backwards two steps in a row, avoiding the attack of the second Zerg that followed.

Seeing that the Zerg was still persevering and following closely, the young man's eyes were cold.

"Look for the dead thing!"

Seeing the sharp insect leg stabbing at him, the young man did not flinch, did not dodge or dodge, and the long sword in his hand stabbed out suddenly.

I saw that the long sword vibrate, and the sword body writhed like a spiritual snake, and it happened to hit the leg of the stabbing worm.

I don't know what kind of huge force is hidden in it, it actually shook the insect's legs directly, and even the body with the insect was driven by the huge force and made a stumbling.

In a flash of coldness, the skull of this zerg was also pierced by the sharp sword tip.

Bang Bang Bang!

Crisp applause rang out, and Tang Yu boasted.

"What a great swordsmanship!"

Hearing this, the young man replied in a cold tone.

"Your knife makes a good job, too."

"It's just hacking."

Tang Yu smiled.

Looking at the movements in the young man's hands at this time, Tang Yu couldn't help but ask.

"What are you doing?"

I saw that the young man suddenly turned over the Zerg who died under his sword, and then stabbed it into its throat with a sword, and the tip of the sword kept stirring inside.

"Look for the worm core."

The young man replied casually.

"Worm core?"

With these two words in his mouth, Tang Yu looked dazed.

Because in the memory of the original Tang Yu, there was no information about the insect core.

Young Xiaohuo glanced at Tang Yu, and seeing that he was at a loss, he immediately raised his eyebrows, and asked in a slightly surprised tone.

"You don't know the worm core?"

No wonder he was surprised.

Because, as a capable person, he doesn't know what the worm core is, such a person is indeed rare.

"I don't know."

Tang Yu was not embarrassed, and shook his head truthfully.

"The worm core is a special substance that only exists in the Zerg body."

"The teeth of the Zerg are all poisonous fangs, and whenever they are bitten, they will be infected with insect poison."

"This kind of poison can only be cured by using serum made from worm cores."

"Therefore, various pharmacies have purchased worm cores from the world to make serums and provide them to those soldiers who are fighting bloodily on the front line against the Zerg."

"Different grades, different species of Zerg, the price of worm cores is also different."

"Like the one in front of us, a first-order ordinary zerg, if the worm core in their body is bought by a pharmacy, the price is generally around five hundred earth coins."

The young guy explained in detail and clearly.

When Tang Yu heard this, he immediately understood the role and origin of the worm core.

Roughly speaking, it is the raw material of pharmaceuticals.

Under his gaze, the long sword in the young man's hand struck upward, and a black shadow flew out of the throat that was stirred by the tip of the sword and fell into his hand.

He spread out his palm, and Tang Yu saw that in the palm of his palm, there was a diamond-shaped dark green crystal, about the size of a thumb tip, presumably this was the so-called worm core.

Tang Yu did the same, and used the tip of his knife to cut the throat of another Zerg. But because it was the first time he had done so, he was clearly not as skilled as the young guy.

After a long time to no avail, he reluctantly bent down, put down the knife, took out a plastic bag to wrap his hand, and directly inserted his hand into the throat of the zerg, groping for it.

After about a minute, he touched a hard object similar to the shape of a worm core. So, he pinched it and pulled it hard.

Looking at the worm core lying quietly in his hand, Tang Yu's face was overjoyed, he succeeded!
