Watching Professor Bai go out, Si Kongchen followed. As he walked, he asked, "Do you mean that you have researched this medicine that still has side effects?"

Professor Bai said: "Surely, this kind of medicine stimulates all the potential energy in your body, but you need a period of time to recover slowly after the stimulation. Because this is not only stimulating the energy in your body, but also in excess Consumption of energy in your body. You can bear it once or twice in a short time, but the third time will make your body unloadable. And the first two excitations have already squeezed out all your energy. Time to recover and squeeze a third time. What do you think will happen? "

After that, the old man glanced at him.

Although Professor Bai has white hair, he has a wide face. But his body is very tough, and the one-meter-nine figure still looks very tall and straight. Walking under the feet is also windy, light and steady.

Xie Longyun is his daughter, but does not share his surname. Because his daughter was young, he divorced his wife and his daughter followed his mother, and later changed her mother's surname.

In fact, his daughter is not close to him, but he only has this daughter now, even if the daughter does not kiss him, he has to take care of her.

After listening to Professor Bai ’s words, Si Kongchen nodded with understanding: “It turned out that! But having three chances to break through a large level of strength is a great help.”

The two walked out of the gate of the experimental area of ​​C, and the old man led him to his office.

"I'm doing experiments on improvement and upgrading, but it still takes time." Professor Bai said after entering his office. Then he picked up the water glass on his desk to pick up a glass of water, and then gave Si Kongchen a glass and turned to him.

After Si Kongchen took the water he handed over, he sat down and looked at him and asked, "So you keep pressing the plan and don't start the action, is it because of this reason?"

After Professor Bai sat in his place, he put the cup on the table. The body leaned back against the back of the chair and waved to him: "No, even if it can only be used two or three times. This medicine is very useful to us. If it is only used to deal with other survivor bases, completely Do n’t worry about what ’s wrong. Even if all the bases add up, they wo n’t be able to support only three or four level 8 abilities. As long as we send a few level 7 abilities to use potions, we can deal with them. Then use us It ’s easy to bomb all their bases, is n’t it? I ’m worried about those things in the underground space now. If this problem is not solved, they are even more threat than human bases. ”

Si Kongchen looked at him and wondered after thinking about it: "Are those things so powerful? Can't we kill them with missiles?"

Professor Bai glanced at him lightly and said, "I guess before your missiles blow into them, they can rush up to grab your missile and throw it back to you!"

His words immediately made Si Kongchen's expression blank, and stared blankly at him: "No? They can still receive missiles? What did you encounter underneath?"

In the third year after the end of the world, Professor Bai actually led people to explore the ground. This probe lasted nearly two years, during which he would send someone to replenish supplies and so on, until he was almost full the next year. He suddenly escaped with a small number of people, and took most of the others, but never got out.

So Professor Bai already knew something about the ground. It's just that the underground creatures suddenly emerged from the ground recently, which made him feel surprised, and guessed what should have changed under the ground.

And since he came out of the ground, he hasn't sent anyone to probe. After another two years of changes, it is difficult to imagine what kind of changes have occurred below. However, after the recent emergence of a large number of unknown creatures from the ground, I can guess that the underlying changes must be very large.

Surviving at this time, the degree of danger is imagined. No, it may be more dangerous and dangerous than you think!

While Professor Bai and Si Kongchen were talking, Xie Longyun below the ground was in a situation.

She wanted to ambush Lin Qiao's, but after the opponent noticed it in advance. Therefore, he temporarily abandoned his intention to deal with the female leader of the sentient base, and prepared to take someone to explore and observe in this underground space for a while, and wait for the female leader of the sentient base to slowly relax his vigilance before proceeding to the next action.

However, before she took someone far, she was entangled by a magic tree. This tree grows very strange. Its tree height is not high, about eight or nine meters, but the branches and leaves are very strong, with a trunk in the middle, and the upper branches grow out in all directions. These branches are very long and long, and they are 20-30 meters long when they are flat. The whole tree looks like a small child with a large umbrella. The leaves are not large, they are only a dozen centimeters long, and they are two-angled, that is, the tail of the leaf is divided into two sides, and the corners on both sides are also carrying a hard tail stab. This thorn is as thick as a baby's little finger and is ten centimeters long. Very sharp!

When Xie Longyun brought people near it more than a hundred meters away, there was nothing moving about the tree, but it was quiet. But when they approached only twenty or thirty meters away from it, the tree suddenly moved.

The original flat tree branches fluttered in the direction of Xie Longyun and others. At the same time, thousands of spikes were shot from the leaves and brushed them.

Suddenly seeing the sharp spikes from this large wave, Xie Longyun and others were startled.

Quickly released abilities to protect them from the outside of their bodies. For them, they are basically level five or six abilities, and the powers released are also five or six. It stands to reason that under normal circumstances, it is completely possible to block these flying spurs.

But the facts are not as they imagined.

"Puff puff--"

"what--"

A scream of screams followed by the sound of piercing the flesh, and everyone was made into a hedgehog!

Only Xie Longyun's skin changed into metal because of the skin on his whole body. But even so, Xie Long went and twisted his delicate eyebrows deeply.

Because although these thorns had not penetrated into her body, when she became a metal body, she could pierce her skin into small pits!
