Hand over the golden finger to the country

After paying the money and delivering the goods, Father Lu handed over a sack to Yan Yan and the others after checking the goods. "Let's count them. There are 156 high-level crystal nuclei, 1786 intermediate crystal nuclei, and 6592 primary crystal nuclei."

Zhou Zhou took it, counted it carefully with Wen Xiao, and after confirming that the number was accurate, he nodded towards Yanyan.

Yan Yan put the crystal nucleus of this sack into the space button, and stretched out his right hand to Father Lu, "We are happy to cooperate."

Father Lu smiled heartily, shook Yan Yan's hand and said, "Happy cooperation!"

After talking about the business, Father Lu still wanted to continue chatting with them for a while, but the secretary was pressing him, and he had other things to deal with, so there was no delay, so Father Lu asked Lu Ke to entertain them well.

Lu Ke originally wanted to take them out for a stroll, but Yan Yan and the others had a "huge sum of money" and their thoughts were all here, and they couldn't wait to go back.

Yan Yan said: "My abilities are a little out of control. Sometimes the place of teleportation is not fixed, and sometimes it is random, so can you help us find a safe and hidden house?"

There are still 24-hour portals in this world, and now they are connected with the people from the Blue Sky Base. They don’t need to take risks everywhere in the future, they just need to bring supplies to trade every month.

It couldn't be more convenient to fix the portal and pass Minglu.

Of course Lu Lin would not refuse, he simply found a single building for them in the office area, and gave the key to Yan Yan and the others, "I will send someone to watch here, and no one will disturb it."

Yan Yan was satisfied, thanked Lu Lin, declined his invitation to play, entered the room, and began to experiment with opening the portal.

I don't know the coincidence or other reasons, Yan Yan opened the portal not long after, the four of them were overjoyed, strode into the portal hand in hand, and disappeared into the room.

When Lu Lin came to call them for dinner at night, he was surprised to find that they had disappeared.

……

Besides, when Yan Yan and the others returned to reality, they stunned the guarding soldiers as soon as they appeared in the glass room.

The soldier pressed the button on the wall with a serious expression, and looked at Yan Yan and the others with a worried expression.You must know that every time they travel, it takes ten days and a half a month, or even more than a month, and they come back within a day.

Are you in any danger?But the portal that was opened yesterday is not open 24 hours a day?The staff who came over were a little puzzled.

"Hurry up! Medical staff!"

Seeing everyone's nervousness, Yan Yan waved her hands with a smile, "Don't be nervous, we're fine."

"This is a bumper harvest, we came back early." Zhou Zhou said happily.

Now the expressions of the staff eased down, with smiles on their faces, "Big harvest? That's great!"

General Yan happened to be on the first floor of the villa. When he came up after hearing the bell, he heard Zhou Zhou talking about a good harvest. He raised his eyebrows and looked at Yan Yan: "Which world did you go to?" The efficiency is so fast.

Yan Yan took out the large bag of crystal nuclei from Space Newly, and said with a smile: "I went to the zombie world. Although there were some problems, they were all resolved, and I even talked about a long-term partner."

General Yan's eyes widened slightly upon hearing this, "There are all crystal nuclei here?"

Yan Yan nodded, "There are many intermediate and advanced ones, nearly 4 in total."

"Wow!" Everyone in the studio was shocked, and then laughed excitedly.

They all know that crystal nuclei can be used to develop drugs to treat cancer. With so many crystal nuclei, how many can be researched and manufactured?This is simply dozing off and sending pillows!

General Yan also had a red face, and the creases of his smile came out, "Okay! Great! Check your body quickly." After finishing speaking, he looked at the staff in the glass room, "The crystal nuclei have been disinfected and sent to the hospital after registration. to the lab building."

"Yes!"

……

When the crystal nuclei were brought to the experimental building, everyone who studied the crystal nuclei was very pleasantly surprised, especially Professor Zhao, who was almost in tears while laughing while holding the big bag of crystal nuclei.

There were not many crystal nuclei left, and he was still worrying about when Yanyan and the others would go to the zombie world again, but he didn't expect that such a large pile would be sent to them.

It was also heard that Yan Yan and others had found a long-term partner in Zombie World. When there was no shortage of crystal cores in the future, everyone was a little dizzy from the surprise.

Old Professor Zhao waved and shouted: "There is no shortage of materials, we have to work harder to live up to everyone's expectations!"

"Yes! Professor!"

After everyone responded, they immediately dispersed and started working again. Each of them was full of enthusiasm.

……

In the next period of time, almost everything is developing in a good direction.

All the yews brought back from the primeval forest were successfully transplanted, and they survived even when mixed with the soil of the present world. For the time being, there is nothing wrong with it.

There are other endangered plants that are perfectly planted in the soil of the virgin forest without any rejection, and even grow better.

It didn't take long for scientists to find an element that is not in the soil now in the soil brought back from the virgin forest. It is definitely because of it that plants can thrive.

Scientists have set up a new research project to study this element, and then look for alternative elements, or exist in some objects in this world.

If the research is successful, there are so many endangered or extinct plants that cannot grow in the interstellar, and it is possible to get rid of those horrible prefixes.

There are also fruits, all of which were successfully planted, and even optimized the seeds and planting methods to increase the amount of fruit.

There are more and more fruits grown at home, and Yanyan and the others bring back some from the virgin forest from time to time, so the price of fruits is much lower than at the beginning.

Some have a relatively short maturity period, and even have been promoted and planted on a large scale, turning into ordinary fruits.

Blue Sky sells it cheaply for itself, but sells it very expensively to the outside world, earning a lot of foreign exchange and enriching the warehouse.

Then there are the things brought back from the advanced interstellar world. Except for various minerals and machine products that have been put into research and production, the progress of the remaining knowledge theory and more advanced robot research is still very slow.

There is no way but to study slowly.

But even so, the supplies brought back from the interstellar world have come in handy.

Among these good news, the only bad news is that Lantian has come up with too many novel things recently, which has attracted the attention of many players.

Knowing that the battle on the front line is still tense, Yan Yan began to think about the high-level interstellar world again. He wanted to get back the space button before, and also wanted to cooperate with Scar again, bringing back some high-tech weapons and warship model materials.

While taking out a lot of good things, you have to take out more powerful weapons. Otherwise, if you can't keep the treasures, you will suffer.

Yan Yan wanted to go to the high-level interstellar world, but failed to do so for several months. The portals she opened every time did not lead to the high-level interstellar world.

Going to the primitive world and the ancient world to earn merits a few times, and then went to the zombie world to trade with the Blue Sky Base. Three months later, Yan Yan finally opened the portal to Scar's world.

The four of Yan Yan took a special bath before going, did a calculation with the theologian, and found that the result was good, so they breathed a sigh of relief.

The outcome is good, but the process is not.

As soon as Yan Yan and the others passed by, they found that the people in front of them were on their backs and were in the middle of a fierce battle.

Four people: "..."
