Watching the roar of the automatic factory, which continued to produce all kinds of daily necessities urgently needed by the base, Song Zheng and the committee members showed a relieved expression on their faces. Bayi Chinese? ＝≤．

At this time, someone suddenly ran in from outside.

"What's the matter?" asked the clerk.

The man said, "It is a miracle tree, and one of them seems to be sick, and its leaves are withering rapidly." ”

The crowd was amazed.

"What's going on?" Song Zheng walked up to the man in three steps and two steps, reached out and grabbed the man's collar, and asked eagerly.

The man had never seen the president so angry, and he was so frightened that he stuttered when he spoke, and it took a long time to finally explain the situation.

Song Zheng threw the person to the ground, turned his head and ran down the industrial building. The committee members also hurriedly ran after him, but they couldn't outrun Song Zheng, and they lost it after a while.

Running out of the industrial building, Song Zheng stopped an antbeast, rode it and let it go outside the dungeon.

The antbeast suddenly sprang up, rampage along the way. When everyone saw that it was the president, and he was still very anxious, they couldn't help but worry, and there were many discussions, and some people chose to run out of the dungeon.

Song Zheng rode the ant beast and quickly ran to the place where the Miracle Ancient Tree was. There was Li Wanru at the door to greet him.

"How's it going?" Song Zheng asked.

"The situation is still getting worse, and the wilt has spread to the branches!" Li Wanru said with a grim expression.

The two walked into the central garden and saw the three miracle ancient trees planted there.

Two of them are lush and healthy. The three trees are separated on three points and arranged in a zigzag pattern, and there is no problem with the two miracle ancient trees side by side in front of them, and the one behind them has no problem.

Walking over and taking a look, Song Zheng's face became more and more difficult to look at.

That miracle tree had withered so badly.

The trunk of the tree still maintained its original appearance, but the leaves had withered seventy or eighty percent, and a large number of dead leaves fell to the ground as if it were raining.

The yellow color is still spreading towards the remaining leaves, and some branches that no longer have any leaves are showing signs of drying.

"Hurry up and save it!" Li Wanru shook Song Zheng's hand and said eagerly.

"Don't be busy. Song Zheng took two deep breaths, "If you don't understand the cause, there is no way to treat it." ”

"What is the cause?" asked Li Wanru urgently.

Song Zheng didn't answer immediately, but walked to the side of the tree, reached out and touched the bark, and without much effort, he peeled off a piece of bark, revealing the trunk inside.

"If the lesion doesn't infect the trunk, then it's not an internal problem, is it an external infection?" Song Zheng said to himself, trying to recall the knowledge stored in his brain.

Suddenly, he felt a flash of inspiration.

"I see!"

In the knowledge in his mind, he found the cause of the disease.

"It turned out to be because of it!"

"What's the reason, have you found the cause?" Li Wanru hurriedly asked.

Song Zheng nodded: "I know the cause, this tree can't actually be regarded as sick, it can only be said to be malnourished." ”

"Malnutrition? But there are special forest rangers at the base, and they all have regular watering and fertilization. Li Wanru's question is also the question of many committee members who have just arrived.

They were very aware of the importance of the elf shop inside the Miracle Ancient Tree, so they specially arranged a forest ranger to take care of these elf ancient trees brought back by Song Zheng on a full-time basis.

Song Zheng gathered them together and explained: "The malnutrition I am talking about is not malnutrition in daily nature, but malnutrition in special periods. ”

Everyone: "......"

"Well, I'll give you an example. A normal fourteen or fifteen-year-old child is growing up and eats a lot every day, and it is impossible for him to be malnourished. But suddenly he was pulled to the national training team, carried out all kinds of high-intensity training, practiced all kinds of projects, and did not rest 24 hours a day, but the food was still the same as before. Isn't it easy to get malnourished?"

Only then did everyone suddenly realize.

"Are you saying that this miracle ancient tree is now in a special period of changing the state of life?" Li Wanru said.

"Not bad. Song Zheng broke off three pieces of bark from the three miracle ancient trees and showed the inside of the bark to everyone. "What difference do you have?"

"This piece of bark has a green pattern on it, as if it was painted!" Li Wanru could see the difference at a glance, because they were obvious in themselves.

"These patterns represent that the Miracle Ancient Tree is about to be upgraded. That's why it appeared. Song Zheng said with a smile.

"It's going to be upgraded, can the Miracle Ancient Tree be upgraded?" everyone looked at Song Zheng.

Song Zheng threw away the bark and said, "Upgrading is a simple image of the statement, in fact, it should be said that the miracle ancient tree is evolving towards the next stage in its life. To put it more figuratively, it can be said that this miracle ancient tree has never reached the stage of adulthood and is growing towards adulthood, but adulthood here is not the definition of time and law, it is physiological. To put it more simply, this miracle tree is sexually mature. ”

"......" Everyone didn't know how to answer.

In the end, it was Li Wanru who asked: "No matter what it is, how can this malnourished state be changed?"

Song Zheng smiled slightly: "Just let it merge with another miracle ancient tree." ”

"Fit ......" many people have a not very healthy picture in their minds.

Li Wanru got started directly, and pinched Song Zheng's waist covertly.

Song Zheng grinned when he was pinched, and hurriedly explained: "It's not the kind of combination you think, it's that two trees merge with each other, and finally become a bigger tree!"

As soon as he said this, everyone finally understood, but many people's faces were also a little red.

It turns out that they all want to go wrong.

"Ahem. What can we do?" asked Li Wanru.

Song Zheng looked at the three miracle ancient trees, thought for a moment, and said, "We can do a favor and put the branches of the two trees together, so that we may be able to speed up the process of merging." ”

"I'm going to move the ladder!" "I'm going to call someone!" "I'm going to get the rope!"

As soon as they heard that they could help, everyone immediately took the initiative to find a job to do, and after a while, they all ran away.

"Everyone is still very positive!" Song Zheng said.

Li Wanru's face turned red, she didn't think everyone was positive, or because of the guess just now, she felt embarrassed and ran away.

Whatever the reason, the people who ran away also did something, and soon there were a lot of base members in the garden.

Everybody's here to help.
