2nd and 3rd floors...... It didn't take long for Li Wenbin and his men to go to the fourth floor of the laboratory building.

In the process of probing before, they easily killed five zombies, and the energy point also reached 16 points. And in addition to Nong Yi, the other two farmers have reached the upper limit of material collection, and they have to use it to continue collecting.

There is no need for Li Wenbin to issue an order, and Bu Yi and others, who are already familiar with the process, take immediate action. Observing, tempting, one classroom after another was searched, and soon, there was a discovery.

Bang bang bang~

After Buyi made a slight movement, there was a slamming sound on one of the doors and the zombie's unique roar.

With a gesture in his eyes, Nong Eryi pushed open the door, and Buyi, who had already prepared, quickly attacked, kicking a female zombie inside to the ground, and the long knife in his hand flashed, ending the life of the other party.

Li Wenbin's energy point also increased a little again, to 17 o'clock.

However, before he could be happy, a whistling wind suddenly sounded, and a black figure rushed towards Buyi, who had just collected his knife, like lightning.

Fast!

It was so fast that he barely had time to react, and before he could block the long knife in his hand in front of him, he felt a huge force coming from the long knife, and his body was knocked back two steps, and the long knife in his hand almost came off.

The black shadow retreated with a blow, and before Li Wenbin could see it clearly, it had already flashed onto the podium in the classroom with the power of the impact, staring at Li Wenbin and the others with a pair of blood-red eyes.

At this time, Li Wenbin finally reacted, the watermelon knife in his hand was raised vigilantly, and his eyes looked at the black shadow.

It was a mouse, but its appearance had changed dramatically.

Even the tail is almost 60 centimeters together, and the fur of the body is mostly black, with a little white doping, which looks very ugly.

This is an evolved white mouse, to be precise, an evolving white mouse, if it succeeds in evolution, all its fur will turn black, and at that time, its strength will be a real first order.

This does not mean that it is not strong now, on the contrary, the strength of this white mouse, everyone present is not its opponent alone. Its sharp claws can easily tear through human flesh, its sharp teeth can easily bite through human bones, and most importantly, it is extremely fast.

"Whew~ It's okay, there is no real evolution completed, otherwise it will be difficult." After careful observation, Li Wenbin breathed a sigh of relief, as long as the other party was not a real first-order creature, he was still very sure.

After all, there are five of them, and none of them are bad in strength.

"Nong Yi attracts the attention of the other party, and Buyi and the others wait for the opportunity to move." Without waiting for the white rat to launch a second attack, Li Wenbin took the lead.

Under his order, Nong Yi rushed forward without hesitation, and the watermelon knife in his hand turned into a cold light, pointing directly at the white mouse.

With a brush, the black light flashed, and the white rat that was still on the podium just now appeared in front of Nong Yi almost in the blink of an eye, and Nong Yi didn't even have time to react before his chest was torn open by its claws.

If there is only one farmer, this battle can be said to be a second kill. However, Nongyi is not fighting alone, he still has teammates.

At the moment of the mouse's attack, the long knife in Buyi's hand, who had been prepared, had already been ejected, and the moment the white rat hit Nongyi, the long knife was also slashed at the mouse's body.

However, the expected slash did not occur, and in a terrible squeak, the white rat was smashed out, and a stream of blood shot out.

Falling to the ground and bouncing, the white rat turned into a black lightning bolt and dodged Li Wenbin's follow-up attack.

The first wave of battles ended.

The rat paid the price for its carelessness, and on its back, a deep wound appeared visible to the bone, and blood continued to spill out, slowing its movements several times.

However, Li Wenbin's side also paid the price, Nong Yi's chest was torn off a large piece of flesh, which looked quite terrifying.

Compared with the two, Li Wenbin's side took advantage, after all, there are many of them.

"Kill!"

Without giving the rat time to breathe, he moved quickly step by step, his long knife obliquely at his side, ready to strike at any time.

Creak~

The white rat had learned a lesson, and this time instead of making contact with Buyi head-on, it began to flash rapidly, constantly changing its position. Soon, however, it realized that something was wrong.

In the constant flashing chase, unconsciously, it has been forced into the corner of the classroom by Li Wenbin and others.

Sensing that he was in a disadvantageous position, the white rat immediately turned into a black light, intending to rush out between the two farmers, and in a short contact, it had already sensed that among several people, the farmer's combat power did not pose much threat to it.

Seeking advantages and avoiding disadvantages, it made choices according to its own instincts. didn't know that he fell into Li Wenbin's trap.

The two farmers did not stop the white rats, because it was difficult for them to stop them, and because Li Wenbin was already ready behind them. As soon as the rat burst out of between the two farmers, he found himself bumping into something hard, and his head was dizzy.

It turned out that in Li Wenbin's hand, there was an extra chair at some point, and when the white mouse rushed out, it smashed directly on its head.

This attack won't kill the white rat, but it will stun the opponent for a while.

And what Li Wenbin needs is this short period of vertigo. The long knife and watermelon knife fell on the white mouse almost at the same time, and after a few brushes, the two legs of the white mouse were cut off, and there were several more wounds on the body.

Finally, step by one to slash the head of the sword and kill it.

——

(Discover energy, do you convert?) ）

——

A familiar prompt appeared, and Li Wenbin chose to be sure.

——

(Conversion successful, Energy +5, Existing Energy: 22.) ）

——

Energy +5, the crystal power on a white mouse, after being converted, actually has 5 energy points, which greatly exceeded Li Wenbin's expectations, and a sense of happiness arises spontaneously.

This is not over, Nong Yi on the side walked to the side of the white mouse carcass and began to collect, the white mouse disappeared, and the collection was successful.

Unlike zombies, creatures with flesh and blood can also be collected by farmers from their bodies. At this point, the three farmer collection limits have been reached.

"Keep searching."

After briefly treating Nong Yi's wounds, Li Wenbin continued to look for his target.

……

5th and 6th floors......

Finally, in a botanical laboratory on the sixth floor, Li Wenbin saw his target, the lightning tree.

It was a half-human-tall plant, and it was impossible to see what its predecessor was, but now it had only two branches except for the main trunk that was the thickness of an arm, and it was covered with leaves the size of a coin, which shimmered slightly, and in addition, there were actually two fruits that flashed with the slightest arc from time to time.

Fruit!

Li Wenbin was excited!

In the previous life, it is said that the god of thunder obtained the ability to control thunder and lightning after eating the fruit of the lightning tree, and now, this ability is in front of him.

Opening the door, Li Wenbin walked quickly to the front of the lightning tree.

——

(Discover special energy sources, do you convert them?) ）

——

As soon as he approached the lightning tree, a prompt immediately appeared in Li Wenbin's mind, and he was so frightened that he hurriedly denied it. This is his own powerful capital, but he can't just take it lightly.
