Seeing Professor Bai walking out, Sikong Chen also walked out. As he walked, he asked, "Are you saying that you have developed this drug and still have side effects?"

Professor Bai said: "There must be, this medicine stimulates all the potential energy in your body, but after the stimulation, you still need a period of time to recover slowly." Because this is not only stimulating the energy in your body, but also depleting the energy in your body. You can handle it once or twice for a short time, but the third time will make your body overwhelmed. And the first two excitations have already squeezed out all your energy, and before you have time to recover, you will squeeze it a third time. How do you think the reaction will be?"

After speaking, the old man glanced at him.

Although this white professor has white hair, his face is full of chasms. But his figure is very tough, and his figure of 1.9 meters still looks tall and straight. Walking with the wind under your feet is also carried by the wind, and the steps are light and steady.

Xie Longyun is his daughter, but she does not have his surname. Because when his daughter was young, he divorced his wife, and her daughter followed her 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 his daughter is not close to him, he has to take care of her.

When Sikong Chen heard Professor Bai say this, he nodded with understanding: "I see, but being able to have three chances to break through to a big level of strength can be regarded as a great help." ”

The two walked out of the door of the C experimental area as they spoke, and the old man led him to his office.

"I'm experimenting with improvements and upgrades, but it's going to take time. Professor Bai entered his office and spoke. Then he picked up the water cup on his desk and took a glass of water, then took a glass for Sikong Chen and turned around and handed it to him.

After Sikong Chen took the water he handed over, he sat down and looked at him and asked, "So you have been pressing the plan and not starting to act, is it for this reason?"

Professor Bai sat down in his place and placed the cup on the table. Leaning back in the chair, he waved his hand at him and said, "No, even if you can only use it two or three times." This medicine is also very useful for us. If it's just used against other survivor bases, don't worry about anything wrong at all. Even if all the bases are combined, they can't support only three or four level 8 abilities. As long as we send a few level 7 abilities to use the potion, we can deal with them. And then use our weapons to blow up their bases, it's very simple, isn't it? I'm still worried about the things in the underground space now, if this problem is not solved, they are even more threatening than the human bases. ”

Sikong Chen looked at him, thought for a while, and then asked suspiciously: "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 hit them, they will be able to rush up and grab your missiles before throwing them back to you!"

His words immediately made Sikong Chen's expression stunned for a moment, and he looked at him blankly: "No, right? They can still pick up missiles? What did you encounter down there?"

In the third year after the end of the world, Professor Bai actually led people to explore the earth. This investigation lasted for nearly two years, during which time he would send people to replenish supplies and so on, until he was almost full of his second year. He suddenly escaped with a small number of people in disarray, and most of the others with him could never get out.

So this Professor Bai actually has some understanding of the underground for a long time. It's just that the underground creatures suddenly emerged from the ground recently, which surprised him, and he guessed what must have happened underneath.

And since he came out of the ground, he hasn't sent anyone down to investigate. After another two years of changes, it's hard to imagine what kind of changes have taken place below. However, after a large number of unidentified creatures have recently emerged from the ground, I can probably guess that the changes below must be very large.

At this time, it will go down, and the degree of danger is imaginable. No, it may be even more dangerous than you think!

And just when Professor Bai and Sikong Chen were talking, Xie Longyun under the ground encountered a situation at this time.

Originally, she wanted to ambush Lin Qiao, but after being detected by the other party in advance. He temporarily gave up his plan to deal with the female leader of the sentient beings base, and planned to lead people to explore and observe in this underground space for a period of time, and then carry out the next operation when the female leader of the sentient beings base slowly relaxed her vigilance.

However, before she could go far with the people, she was entangled by a magic tree. This tree grows very strangely, it is not very tall, about eight or nine meters tall, but the branches and leaves are very vigorous, and there is a main trunk in the middle, and the branches on the top grow out of the cloud horizontally in all directions. The branches grew very long, twenty or thirty meters long, and the whole tree looked like a child carrying a large umbrella. The leaves are not large, only a dozen centimeters long, and they are biangular in shape, that is, the tail of the leaf is forked into two sides, and there is a hard tail thorn on the horns on both sides. The spine is as thick as a baby's little tail finger and is ten centimeters long. Very sharp!

When Xie Longyun led people closer to it for more than a hundred meters, there was no movement in the tree, but quietly. But as they approached it only twenty or thirty meters away, the tree suddenly moved.

The branches that were originally stretched out shook and slammed in the direction of Xie Longyun and the others, and at the same time, thousands of spikes shot out from the leaves and stabbed towards them.

Suddenly seeing this large wave of spikes shooting densely, Xie Longyun and the others were startled.

Hurriedly released the ability to protect the periphery of their body, for them, they are basically five or six level of ability, and the ability released is also five or six level. It stands to reason that under normal circumstances, it is completely possible to block these spikes from them.

However, the truth is not as they imagined.

"Puff puff—"

"Ahh

Bursts of screams rang out with the sound of flesh being pierced, and everyone was pierced into hedgehogs!

Only Xie Longyun didn't end up like them because the skin of his whole body turned metal. But even so, Xie Longgo was deeply twisted into his delicate eyebrows.

Because although these thorns didn't penetrate her body, they could pierce her skin into tiny pits when she turned into metal!
