Facts proved that Wu really knew Fengyun very well. When he left from him, his determination to try out the rainbow rice did not waver at all. After he decided to go back, he prepared for the experiment.

In fact, when he proposed to Wu Hefeng to use planting methods to increase the yield of rainbow rice, he had not never thought of the difficulty of its planting.

As Wu said, if rainbow rice can be easily planted successfully, someone will plant it long ago. Although limited by knowledge, primitive people handled some things with thick lines, but many tribes have mastered planting techniques.

However, Fengyun believes that the rainbow rice must be successfully planted. The reason why it has not been successfully planted is that it has not found the correct planting method.

What supports him is his experience before crossing. With the improvement of scientific research level, some plants that were considered impossible to be successfully planted in the past have been artificially planted.

Fengyun is confident in the success of planting rainbow rice, but he did not act blindly, but was ready to think about it before proceeding.

It has been a long time since Rainbow Rice was discovered, and there must be more than one or two people who had the same idea as him and put it into practice, but they all failed.

Of course, it is possible for someone to succeed but conceal the news of their success, but one thing is certain, that is, it must be difficult to grow rainbow rice.

Since it is difficult, you cannot act rashly, otherwise what is waiting for him is likely to be a failure, and failure means that the rainbow rice used for planting will be lost.

This time the difficulty of obtaining rainbow rice has been greatly reduced due to various reasons, but this does not mean that he does not value them, and it does not matter if he loses them.

"Brother Yun, you are back. Hurry up and I will tell you in detail what you encountered when you went out this time. I warn you, you can't fool us anymore, otherwise..."

As soon as Feng Yun stepped into the courtyard, Feng Bei screamed, wondering if she was deliberately waiting for Feng Yun, she happened to be in the courtyard when he came back.

"Bei, I have something to do, I will tell you when I have time."

Feng Yun waved his hand at Feng Bei and walked to the room where he lived.

"Brother Yun, you..."

Feng Bei raised his voice, trying to express his dissatisfaction, but was stopped by Mulanzhi standing next to him.

"Sister Laneige, why are you stopping me?"

Feng Bei turned to look at Mulanzhi, showing a puzzled expression.

"Sister Bei, I think Yun is really something, so let's not disturb him."

"Something? Why didn't I see it?"

Although Feng Bei said so, he didn't stop Feng Yun, let him walk into his room and close the door.

As soon as Feng Yun inserted the door, he walked quickly to the table, poured some water into the inkstone, and took a piece of ink to grind it.

During this process, his brows have been frowning slightly, showing a state of thinking. He is thinking about the possibility of failing to plant rainbow rice.

After grinding the ink, put the remaining ink into the box, unfolded a piece of paper, pressed it with a jade ball, grabbed a small brush, dipped the ink, and began to put it on the paper Wrote it.

At first he wrote very smoothly, almost never stopped, but soon he slowed down, often after thinking about it for a while before writing a line or two.

It’s not surprising that this happened. At the beginning, he wrote quickly. It was entirely because he had been thinking about it from the time he left the witch’s residence to when he finished studying ink. He had already gained some experience and it was naturally easy to write. He wants to write now, and the speed is slow.

After about an hour, Feng Yun will finally put down his pen, and the piece of paper in front of him is basically covered by the font.

Based on the relevant knowledge he acquired before crossing, he summarized the possibility of the failure of planting rainbow rice, temperature, humidity, water and fertilizer, light, pollination, insect pests...divided into categories, Fengyun recorded everything it could think of.

Putting down the pen, Fengyun began to read the content he had recorded word by word, then spread out a piece of paper, grabbed the pen, and wrote on it.

He is extracting relevant knowledge from his mind to find solutions for these reasons that may lead to the failure of planting rainbow rice.

"Da da da……"

Once people focus their attention on a certain thing, they often ignore the passage of time, and the situation is the same. It is not until a knock on the door that they awaken him.

"Who? What's the matter?"

Feng Yun raised his head and looked at the location of the door, his tone of voice revealed obvious impatience.

The knocker didn't seem to think that he would make Fengyun so unhappy. He didn't respond immediately. Instead, he said after a while, "Brother Yun, it's me. Sister Hong made dinner and let me ask you to eat. It."

"You go eat. I'm not hungry."

Feng Yun cast his gaze on the paper in front of him again. He did not expect to find a solution to the cause of his failure, and he was temporarily unable to eat.

"Brother Yun, do you have anything to do? Can't you just let it go? You will have more energy to do it after eating. Besides, you can talk to us, maybe we can help you."

"Okay. I'll be here."

Feng Bei's persuasion seemed to have worked, Feng Yun put down the pen, got up from the chair, and walked to the door.

Feng Bei's words reminded him that he thought of someone who might help him in growing rainbow rice, and she was Magnolia.

Magnolia comes from the Baicao tribe. The people of Baicao tribe are proficient in medicine and often need to use various medicinal materials. When this happens, they will grow various medicinal materials by themselves.

There may be a big difference between planting medicinal materials and planting rainbow rice, but they are both planted, and there must be similarities. The knowledge of planting medicinal materials may be able to help him.

"Lady Laneige, have you been free recently?"

During the meal, Fengyun asked Mulanzhi.

"Since everyone has formed an alliance, there has been less competition, plus the knowledge you have imparted to everyone, the difficulty of obtaining food has been reduced, the number of hunting trips has decreased a lot, and the number of injured people has decreased a lot. Compared with the past, I am much more relaxed. Quite a lot."

"This is really great. I want you to do me a favor. I'm still worried that you don't have time."

Mulanzhi's answer made Fengyun relax. If she is very busy, he wants her to help him, and it is not easy to speak.

"What's the matter? Just say it. Don't say I have time, even if I don't have time, I will make time."

"I want you to help me grow rainbow rice."

Feng Yun glanced at everyone present, and finally fell on Mulanzhi's face with a very serious expression.
