"Rain, are you sure it's here?" Professor Bai asked, knowing that the rain had stopped at the bottom of the sea.

"Don't argue, don't argue, I'm reminiscing."

"Well, it should be here." The rain searched the ocean bottom for a while, and finally found an inconspicuous place.

This is a rock layer, the surface of which has long been filled with sediment.

"Uh, that rain, how are you going to get in, do you need a spell?" Wang Lin looked through the light, it didn't look like there was a passage entrance.

"You've seen too much." Yu glanced at Wang Lin, "Captain, you have to take care of it yourself if you can't get in, don't put your life into it." ”

"Understood."

"Alright, two lumps of fat, ready to go in." The rain shouted at the two of them, and then slammed the front of the car into the rocks.

"Damn, I haven't married a wife yet." Professor Bai suddenly screamed when he saw the momentum of the rain hitting the wall and committing suicide.

Wang Lin also wiped the sweat on his forehead with his hands, listening to the rain, if he didn't step on the pedals, the protective film would disappear, and then he and Professor Bai might be pressed into cakes.

With a "boom", the sediment was knocked up, and the ancestral car crashed out of a hole and rushed directly into it.

“。。。。。。” Captain Karl looked at the three people who went in the monitor, and didn't know what to do, this stone is rolling now, will there be a problem with his ship when he passes over?

"Captain? Are we going to follow? The crew swallowed and asked, although they also wanted to go in and have a look, but this was obviously not suitable for their own follow-up.

"Uh, forget it, let's stay outside." Karl sighed, still not daring to gamble with his entire ship's life.

Wang Lin and Professor Bai closed their eyes and shouted loudly for a while, and then they were pinched hard before closing their mouths.

"We're in?" Professor Bai opened his eyes and saw a water world of Youlan.

"Nonsense, or where do you think you are." Yu stepped on the pedals as he took out the food from the bag on the body of the car and ate it.

I'm really tired, isn't Lao Zhang stepping on it very easily, is this the relationship between the masters?

The three of them walked in the water for a week, and they were so tired that the rain almost dried up, and finally came to the edge of the big tree.

Looking at the current appearance of the big tree, Yu was suddenly taken aback.

The tree looked like it was healthy at the beginning, but now it looks like the tree is about to die, the original leaves have become dry, and some thick branches seem to have little life.

"Big tree, big tree, what's wrong with you, sick?" The rain climbed up the trunk of the big tree and came to the mouth of the tree hole, only to see that the ground pulp inside was still full, as if it had not been used much.

"Ah, it's rain." After a while, the weak sound of the tree came from the hollow of the tree.

Although Wang Lin and Professor Bai have heard about this matter, their perception is completely different from that of their own experience.

"What's wrong with you, why don't you drink this water?" Yu almost burst into tears when he heard the weak voice of the big tree, "Did Lao Zhang pick all your fruits, so your body is not good?" ”

"Regardless of Zhang Hengyou's affairs, I feel a darkness, and this darkness is getting stronger and stronger."

The three of them were shocked, and the rain hurriedly said, "What darkness? ”

"I don't know, I just feel that something is growing far away, it is approaching you, it is powerful, so it hurts me on the soul level."

Professor Bai and Wang Lin were shocked, they didn't know what it was, but they knew that a crisis was coming.

"Can you describe the darkness?" Wang Lin was the first to ask.

"Fear, evil, unable to resist. I felt it once a long time ago, but then it seems to be quarantined, but lately it seems to be getting stronger. ”

"What then? If this continues, will you die? "Yuyu said.

"Yes, this is an unchangeable ending, and you have to be careful." The big tree seemed to be a little weaker after so many words.

"Can I take some of the sap from your trunk, then?" Professor Bai was silent for a while before speaking.

As soon as Yu heard this, his whole body immediately exploded, and he jumped and pointed at Professor Bai's nose and scolded: "Old man Bai, what do you mean, the big tree is so weak now, you still have to go to pump the sap, you must know that the sap of the big tree is the same as our blood, do you think the big tree dies fast enough?" ”

"Calm down in the rain." Professor Bai looked at the rain with a serious face, and waited for the rain to calm down before continuing: "The death of the tree is inevitable, and I am also very sad, but you have to understand, what is the significance of this research? ”

"If the darkness is too strong to resist according to the meaning of the tree, will we just sit back and watch the life of the planet we live on be destroyed at the hands of that evil thing?"

"Now we can only gain a little hope in the next war by striving to improve our own human strength."

"Rain, this friend by your side is right, if there is anything else on me that can help you, you can take it." The big tree spoke.

"And ah, isn't my child already handed over to you, it's my continuation, you help me take care of it, and seeing it is like seeing me."

The rain wiped away his tears, and Professor Bai asked the big tree to stretch out a branch, and it took a lot of effort to get a tube of the essence sap of the big tree.

For this tube of sap, the branch of the big tree was almost broken, and the transportation pipe on the section was almost dry, and the big tree was already extremely weak.

After seeing Professor Bai packing up his things, Yu said, "Big tree, do you have anything else to want?" ”

"Oh, by the way, let Zhang Heng come after you go out in the rain, let him take back the liquid in this tree hole, I don't think I can use it either, you might be of some use if you take it back."

Professor Bai and Wang Lin bowed to the tree, then got on their bicycles, and the three of them left together.

The atmosphere is very depressing, this tree of life that has lived for tens of millions of years is actually going to die, which is a difficult thing for the three of them to accept, let alone rain.

After being silent for a long time, Professor Bai finally couldn't hold back anymore and asked, "What is the liquid of the big tree?" ”

"That's what you injected Zhang Heng."

“。。。。。。” Professor Bai could already stuff a fist into his mouth, if it was replaced by the rain in the past, maybe now he would be a punch in and smash a big tooth.

"Damn, there's liquid from a tree hole. Hell, we've only collected half of it in the planetary belt, but it's only a little bit. Professor Bai was furious.

Cut, this old man is so excited, if he knows that Lao Zhang has a big pool of this thing, it is estimated that ten bottles of fast-acting heart pills will not be able to save it.
