"Buzz!"

Only a slight tremor was heard. At the moment of blood dripping, the whole thunder spear suddenly trembled violently. Then, in Duan Fei's and Li Feng's slightly surprised eyes, the originally ugly thunder spear changed dramatically in an instant.

The blue light flashed slowly. At this moment, the simple and complex patterns on the whole staff seemed to come alive, shining with dazzling light, like insects, creeping slowly on the iron bar, converging to the center of the iron bar, and then spreading towards Duanfei's arm.

"Gene testing starts!"

"Start matching..."

"Matching succeeded..."

"Gene information begins to be accepted, and the main recognition function is turned on..."

A series of cold electronic sounds rang out in Duan Fei's mind. Under this sound, Duan Fei felt as if an extremely strong current suddenly poured out of the thunder spear and broke into his body. At this moment, Duan Fei's whole right arm was paralyzed.

"This is to enhance the compatibility between your body and thunder. Otherwise, as soon as you start the thunder spear, you will be shocked to death by the powerful force above!" When this current appeared, Laurie, an evolutionary tree, slowly explained.

Strong current comes and goes quickly. In less than a second, the current immediately disappeared, the extremely strong sense of paralysis on the arm gradually disappeared, and the consciousness gradually recovered.

"Recognize the Lord successfully!"

After an electronic sound, Duan Feichang breathed a sigh of relief and looked down.

At this moment, the slender iron bar in his hand, which was originally dark gold, had completely changed into another shape.

The smooth staff body is like crystal, showing a pure blue. In the translucent staff body, the blue energy slowly surges, and a terrible wave slowly disperses from it.

After recognizing the Lord successfully, Duan Fei and the thunder spear have been connected. Duan Fei only needs to move his mind, and the thunder spear will immediately become the form of attack.

However, the thunder spear is only a replica after all, and can only be used once. Once it is started, it is equivalent to that the thunder spear has been scrapped. Therefore, although Duan Fei wants to see what the thunder spear in full state looks like, he still suppresses his inner curiosity and puts it away.

"Ah Fei, how did this thing become like this!"

Looking at the changed shape of the thunder spear, Li Feng's eyes also twinkled with curiosity. Feeling the energy wave, he knew that the thing in front of him was no longer the very ordinary iron rod, but became a powerful killer.

"I don't know!" Duan Fei smiled and said, "I read many treasures in novels. As long as I put blood drops on them, I can successfully take them. I tried to drop them. I didn't expect it to be like this!"

"Sleeping trough, that's OK!" Listening to Duan Fei's words, Li Feng suddenly looked speechless.

What a coincidence that a blind cat meets a dead mouse!

Looking at Li Feng's face, Duan Fei smiled and said nothing more, and then let another thunder spear recognize the Lord.

In fact, Duan Fei really didn't know the true identity and function of the thunder spear if it wasn't for the explanation of Laurie, the evolutionary tree. Although Duan Fei was told by Laurie of the evolutionary tree, Duan Fei couldn't tell the truth in front of Li Feng, so he had to tell another lie.

It does exist in many novels. Although it sounds ridiculous, it is reasonable to think about it carefully, so Li Feng has no doubt.

After taking the last thunderbolt spear, Duan Fei looked at the energy vortex emitting strong light on the wall behind the wooden box, and finally a retreat came into his eyes.

On the fourth floor, facing the vine monster, if it weren't for the evolutionary tree, I'm afraid I and Li Feng would have to plant here. Therefore, facing the next more powerful fifth floor, Duan Fei doesn't want to enter the exploration.

Duan Fei clearly remembered that in the guidance volume, the only red dot on the fifth floor, its light almost covered all the red dots in the whole ruins, and even the red dot on the fourth floor was far less than it.

What does that mean?

This means that in the fifth layer, there is a monster more dangerous and powerful than the vine monster. Facing the vine monster, Duan Fei felt powerless. If he faced a stronger existence than the vine monster, Duan Fei could not survive at all.

Of course, if you want to kill it, Duan Fei can still do it with a thunder gun. However, the thunder gun is too powerful. Once used, maybe the whole ruins will collapse directly under this huge force. Therefore, Duan Fei doesn't want to take this risk.

After weighing the pros and cons in his heart, Duan Fei told Li Feng about his decision.

After hearing that he was ready to turn back, Li Feng immediately raised his hands in favor. In fact, when he was on the fourth floor, he wanted to stop and go back. Now he was lucky to be able to kill the vine monster. If he went deeper and met such a terrible monster, there would be no way back at that time.

Just accept what's good is the king of survival.

"Let's go!" After looking back at the ruins of the fourth floor, Duan Fei and Li Feng walked side by side and quickly walked towards the entrance.

However, at this moment, the accident suddenly occurred.

"Boom!"

In the silent lobby, there was a loud noise. After the loud noise, the whole fourth floor ruins began to shake violently, and the dense cracks filled the whole dome like broken ice.

Hearing the loud noise, Duan Fei suddenly turned back and looked at everything in front of him. His face suddenly changed.

……

At the same time, the fifth floor of the pagoda.

"Boom! Boom! Boom!"

In a series of explosions, ten figures collided with a monster about four or five meters tall, and then suddenly separated, like ten galloping lightning, shooting in all directions.

When the dust dispersed, in the center of the hall, a monster somewhat similar to human beings appeared in front of everyone. It was half kneeling on the ground, covered with dense scars, and its dark pupils were full of angry flames.

Around it, brother long, four of them and six other people in black tightly surrounded it in the center. Everyone exuded incomparably strong energy fluctuations and cold murderous Qi, which tightly locked the monster in the center of the hall. Once the monster changed slightly, the one waiting for it was a thunderbolt attack.

"It can't hold on. Let's go together and kill it completely!" Looking at the panting monster in front of him, brother long flashed a cold light in his eyes.

After hearing brother Long's words, everyone was silent, but their body movements were consistent. At the moment when their bodies stopped, everyone shot again and sped towards the monster.

Brilliant powers, all burst.
