I, the one in the heavens, am here to protect my bottom line in all realms.

Chapter 326 Handover and Departure
After dinner, they returned to the conference room and started discussing the deal.

Zhang Chengyuan directly stated the quantity he had and decided on the items to be traded, allowing them to choose.

After the deal was negotiated, it was time to discuss the details of the greening cooperation. She was straightforward again: "My cooperation with you is only to provide saplings, and you decide the rest."

The person in charge was speechless for a moment. He was used to quarreling, so he was not used to such a sudden straightforward response. His distracted thoughts only lasted for a moment, and he quickly thought about what needed to be done for the greening project.

The first step is to reduce radiation, which requires planting more plants like Larix gmelinii. This can, on the one hand, prevent wind and sand and reduce the dust in the air, and on the other hand, reduce the radiation content.

The second step is to plan farmland and orchards. If you want other bases to actively cooperate, you will inevitably need inducements and enough bargaining chips to prevent them from lagging behind.

As long as these two points can be achieved and the military strength is not weak, greening can be implemented quickly, and the next three, four, five, and six steps will not be a problem.

The more he thought about it, the more excited he became. The person in charge couldn't help but show some emotions on his face. Zhang Chengyuan and the others looked very kind.

Seeing that the discussion was settled, Zhang Chengyuan stood up and said, "We will go back first. You decide who to arrange to pick it up."

She thought about it and decided to leave. Given the person in charge's current situation, no matter how many days they stayed, he would probably try his best to prepare the best for them.

As for the tea just now, although it was filtered very clean, it still had a faint radiation, so they didn't drink it. In this case, if they still stayed here, the food and filtered water, which were in short supply, would definitely be used by them first.

Although this base is already very good, there is still a shortage of water and food. They don't need these things, so why should they take away other people's food? One of them may be life-saving food.

Therefore, she decided not to stay, and also because she felt that it was not as comfortable here as at home.

The person in charge tried to persuade her to stay, but Zhang Chengyuan refused sternly, saying that she wanted to go back as soon as possible to cultivate young seedlings.

Upon hearing this, the person in charge not only did not try to keep them, but also urged them to go back quickly and sent a car to take them back, saying that this would be faster.

In response, Zhang Chengyuan twitched his lips but he could understand it, so he didn't refuse and took the bus back.

The person driving the car was an old acquaintance, Mu Yangjin. He had volunteered for the job. It was good for him to be able to spend more time with his beloved.

Although he knew that there was no possibility between him and her, he just couldn't help wanting to be closer to her, closer and closer.

Zhang Chengyuan and others saw it, but no one pointed it out.

After all, it's their freedom to like whoever they want. There's no need to interfere too much. It doesn't bother them anyway.

After being sent home and getting off the car, Zhang Chengyuan did not invite Mu Yangjin into the house. Instead, he asked him to wait for a while and went back to pack a few seeds and handed them to him: "Take them to your person in charge and try to plant them. These are good varieties."

Mu Yangjin stared at the silkworms for a few longing eyes, then stepped on the accelerator and drove away.

The four people returned to the yard and found a place to lie down. Riding in a car is not a comfortable experience. After a long time, they felt uncomfortable everywhere.

Six days later, Mu Yangjin came again. He brought the items that Zhang Chengyuan wanted to trade and took away a truckload of seeds.

Those seeds were all grown by her using her resources and her own abilities, so there was no change, as if they were naturally grown in a radiation environment. The day after Mu Yangjin left, they started digging holes and planting trees again, because Zhang Chengyuan cultivated other tree species that could absorb radiation, and they continued their greening project.

During this period, Jin Chusheng came back twice. Seeing that they were all busy, he also followed them and worked for a few days before leaving.

Half a year later, Mu Yangjin's base was finally integrated with other bases. From that day on, the speed of greening increased exponentially.

In less than a month, the country's greening rate reached 50 percent.

With thirty days left, the greening was completed. On that day, Zhang Chengyuan obtained a stone, which was a reward from the card drawing system for completing a hidden task. After identification, it was found that this thing was a promotion stone.

As the name suggests, it is used for advancement, but this thing is not for people but for the world.

It turned out that in the Kunling Star Region, the promotion of the world actually depended on promotion stones. Unlike what she had known before, the promotion of the world here had another set of rules.

For example, a newly born world needs one promotion stone to upgrade twice to become a small world. A small world needs one promotion stone to be promoted to a medium world, ten promotion stones are needed to upgrade from a medium world to a big world, and one hundred promotion stones are needed to upgrade from a big world to a great world, and so on.

The amount of advancement stones you obtain depends on the level of the world you save.

For example, one piece for the small world, five pieces for the medium world, fifty pieces for the big world, five hundred pieces for the great world, five thousand pieces for the chaotic world, and so on.

For her, the star field turbulence is a good place to gain energy. If she had not accidentally tried to obtain more energy, she would have had no chance of obtaining the promotion stone. She knows this.

She stared at the promotion stone in a trance. If she followed the promotion method of Kunling Star Domain, then if she wanted to be promoted to the mythological world, she would need 10,000 promotion stones, which was not difficult.

But if you use the promotion stone to get promoted, then after the promotion you will automatically own a star field in the heavens or you will be left alone. You can then slowly conquer it or just wait for time to give birth to your own star field in the heavens.

After going through this idea in his mind, Zhang Chengyuan understood that the advancement to Shi Jin should be in a single world. If he could really automatically own a star field in the heavens, the Kunling star field in the heavens should have been upgraded long ago.

After thinking it through, she was a little disappointed and sighed, but she had a new idea. Although it was an advancement to a single world, she could still do a lot, such as mass-producing large, medium and small worlds. Once the base number became huge, it would not only bring hope for expansion, but also the possibility of creating a star field in the heavens.

Just as she was thinking about it, Jin Chusheng suddenly appeared nearby. Zhang Chengyuan looked over and saw Jin Chusheng's desire for the promotion stone. Just when she thought Jin Chusheng would say something, he turned around and left.

Zhang Chengyuan touched the promotion stone and looked at Jin Chusheng's lonely back as he left. He had no intention of giving it away, even though he knew he needed it very much.

He needs this thing, and she needs it too. Naturally, it is impossible for her to harm her own interests for an outsider. This kind of thing will never happen to her.

Zhang Chengyuan put away the promotion stone and began to pack her things in preparation for leaving. First of all, she wanted to take away all the things she had made. As for the remaining food, clothes and other sundries, she planned to leave them to the people in this world.

Although people's living environment has improved a lot in the past six months, they have not yet reached the state of having no worries about food and clothing, and life is still very difficult.

With her supplies, at least they can feel a lot more relaxed.

In addition, there are various good varieties and young seedlings in the sub-gardens, which are enough to green another country as big as this one.

After cleaning up this and that, twenty days of a month were spent.
