After handing over the Wanjie Trading System, the motherland ranked first

"This is my little thought. I hope we can continue trading in the future and have a happy cooperation..."

"Of course, thank you Mr. Bai, I think we will be a good partner!"

Under Gungun's operation, the two quickly completed all the transactions. Mu Qingzhi took a look at the contents of the system backpack and walked out of the room...

Mu Qingzhi had just walked out of the room when she heard Lu Xingze's deliberately lowered voice,

"Qingqing, come over and eat together. I left some dishes for us to eat together..."

"Okay, I'll go over right now!"

Mu Qingzhi washed her hands and went to the restaurant, but she only saw Lu Xingze, not Mr. Zhang...

"Where is Grandpa Zhang? Why don't you ask him to eat together? If Grandpa Zhang finds out that you are eating delicious food behind his back, he will be angry~"

Lu Xingze walked to Mu Qingzhi's side, pulled out a stool for Mu Qingzhi to sit down, and then returned to his seat...

"Grandpa Zhang is sleeping. He should take a good rest after staying up for so long. And I also left some food for him, so I don't have to worry about him getting angry when he wakes up~"

"In that case, let's get started~(???)?"

Mu Qingzhi and Lu Xingze began to enjoy the food openly, while Zhang Laozheng in the other room slept soundly...

The two of them finished their meal soon. After Lu Xingze simply tidied up the dining room and kitchen, he and Mu Qingzhi tidied up Mr. Zhang's temporary room.

Finally, Lu Xingze left a note on the table and told Mr. Zhang that he and Qingqing would go back without disturbing him. He also left some boiled cabbage for him so that he would not forget to eat it...

Lu Xingze and Mu Qingzhi quickly returned to Mr. Long, and then handed over to Mr. Long the production method of the low-end version of the nutrient solution, three bottles of nutrient solution, the treatment device, and the production methods and materials used for the treatment device. Then he took out 2 more energy stones and handed them to Mr. Long.

"Grandpa Long, these things are the result of this transaction. The treatment device, its production method and materials were given to us by Bai Qingyue. I took a look at the records inside and they are very clear. If they are handed over to professionals, they should be able to analyze them soon. Copy it..."

Mr. Long was very happy looking at the various things placed on the table, especially the manufacturing methods of the treatment instruments.

"Xingze, Qingzhi, and Old Man Zhang, you did a great job this time. We are honored to have you in our country, hahaha~"

"Grandpa Long, it is our honor to be born in the Dragon Kingdom~"

After Mu Qingzhi and Lu Xingze handed the things to Mr. Long, they didn't care about the follow-up. They just heard that Mr. Long quickly summoned relevant personnel to start secret research...

…… …… …… …… …… …… …… ……

Time flies to November 2223, 11. Lu Xingze and Mu Qingzhi have been walking around from time to time recently to avoid unknown wild evolution movements.

Fortunately, nothing unusual was found for the time being. Mu Qingzhi was planning to rest at home for the next two days when she received a call from Mr. Long. There was a rare hint of depression in his voice...

"Hey, Grandpa Long, what's wrong with you? Are you unhappy with anything? Tell us and see if Lu Xingze and I can solve it~"

"Girl Qingzhi, the thing is like this, we have been developing the formula of the nutrient solution smoothly, but now there is a problem that has been bothering us, alas..."

"What's the problem? Can even my Grandpa Long be stumped?"

"There are two materials in the nutrient solution formula that we have never developed. We have looked for a lot of things, but they are not suitable for these two materials. What is always missing?

The old die-hards at the institute worked day and night. Not only did they collapse from exhaustion, but they still figured out what these two things were and what they could replace them with. The people at the institute advised them to give them a rest, but these die-hards They didn't listen at all. I asked the soldiers to take them away during a forced holiday. Then they went home to rest..."

"Grandpa Long, what did you use to compare these two missing materials?"

"All kinds of food and plants, you can't use things that have nothing to do with food in the nutrient solution..."

"Grandpa Long, you have solidified your thinking. They are from the interstellar world. They are different from us. Besides, there are many things that we have not studied to understand their specific effects. Maybe it is a 'stone' on the outside, but it is soft and usable on the inside. Where’s the stuff?”

After hearing Mu Qingzhi's words, an idea flashed through Mr. Long's mind. Fortunately, Mr. Long caught this idea...

"Girl Qingzhi, I won't tell you anymore. After you reminded me, I suddenly came up with an idea, which might be really useful. It seems that the brains of young people like you move faster. You can't accept it anymore, haha~ "

Mr. Long quickly hung up the phone, and then contacted the researchers. Hearing Mr. Long's ideas, he was suddenly enlightened and went straight back to the research institute to develop it again...

Mu Qingzhi looked puzzled when the phone was hung up.

"Lu Xingze, what did I say that Mr. Long had an idea?"

“Maybe let them try different types of things instead of just looking at food and plants?”

"It's possible, Lu Xingze, what do you think is happening in other countries now?"

"I don't know, but the countries we cooperate with should have a relatively easy time. As for other countries, I don't know. After all, sometimes too much freedom can easily lead to trouble..."

While the two were chatting, Lu Xingze's phone rang. He took out his phone and saw that it was Mr. Long.

"Mr. Long, are you calling Qingqing?"

"No, I'm looking for you, Xingze. There is a difficult matter now. I can only rest assured if you handle it!"

Mu Qingzhi looked at Lu Xingze with some confusion when she heard Mr. Long's serious voice. She couldn't remember what happened at this point in her previous life...

Lu Xingze gave Mu Qingzhi a calm look, and then continued to listen to Mr. Long's instructions.

"Xingze, is that girl Qingzhi here too? You guys should listen together..."

"Okay, Mr. Long!"

"Girl Qingzhi, I need to borrow the Xingze by your side. What happened is not our country, but the country of White Bear Country. They have a land border close to the island country, which has been contaminated by nuclear sewage some time ago. They found animals that were mutated by nuclear sewage pollution. They could still deal with them at that time, but it was difficult for them to deal with the mutated animals that appeared this time, so they asked our country for help, and Xingze's support was the best solution we developed. ..."
