Of course, in order to upgrade the equipment resources of the system to a higher level and make this cake bigger, what cannot be avoided at present is the much-needed californium.

The system can help collect natural resources, but the system will not go out of its way to help him build a device that can produce artificial element californium, and there is no such 'backward' facility in the construction list of the base.

This still has to be done by Zhang Yide's own efforts.

Chen Chong gave Zhang Yide half an hour to prepare, and then the two sides gathered at the teleportation node closest to New York in the United States.

In fact, the high-level officials on the American side wish that the people on Zhang Yide's side would be there immediately to deal with those monsters, but this half an hour of time is necessary, Chen is important to gather people, and at the same time, he must also make some arrangements to prevent any accidents in the Celestial Empire when he is not there.

Therefore, half an hour was set aside for Zhang Yide.

This is not a long time, and Zhang Yide did not waste it.

He returned to the moon with the Book of Fuxi, found the production line and materials he needed in the Heavenly Palace, and summoned them to the underground factory in Batti City.

After doing all this and asking the Book of Fuxi to make a few new drone splits to be responsible for the assembly and debugging of the production line, he took Zhan Ji and the Book of Fuxi to say goodbye to Leah and embarked on the teleportation node to the United States.

By the way, the system defaults to the fact that the Book of Fuxi is an item belonging to Zhang Yide, so the Book of Fuxi can be teleported away with Zhang Yide without hindrance.

The Book of Four appears in a strange house.

This house is a typical American farm house, a wooden single-storey house, nice decoration, but probably because it has not been inhabited for a long time, this house is now covered with cobwebs and dust, and with the messy and overturned furniture around it, it looks like the whole house is full of post-apocalyptic dilapidation.

No one has come here yet, Zhang Yide is the first to arrive.

As soon as Jiujiu saw the new environment, she couldn't help but flick her tail and look around, regardless of the cobwebs and dust, and soon she found something she was interested in, and raised it to greet this side: "Look, Zhang Yide Thorn~~ Jiujiu has found a gold ring!"

"Idiot, call me Nineteen outside!" Thorn scolded with a bad face, and Ninety-Nine stuck out his tongue, smirked unappetly and ran back, holding the gold ring and handing it to Zhang Yide.

Jiujiu knew that Zhang Yide needed gold, and all commanders needed gold, even if the gold weight of this ring was so small that it could be ignored for Zhang Yide, but it was also gold!

Zhang Yide smiled, reached out and rubbed Jiujiu's white hair and hairy ears, and then took the gold ring and absorbed it into the phone.

When he did this, the teleportation node flashed again, revealing the figures of four people.

Chen Chong, Tom, Maud, Linn.

Two pairs of acquaintances appeared in front of Zhang Yide.

"Hey, Maude, Lynn, I didn't expect that the person Uncle was looking for this time would be you. Zhang Yide greeted the two first, while Lin nodded slightly in response, and Maude said with a hearty smile: "No way, I got too close to the military and was arrested." ”

The sense of responsibility and combat effectiveness shown by Maude last time when he assisted the military in the battle made many soldiers in the military unit familiar with this man, and often the military encountered any problems that were difficult to solve, and he lost the qualification to use the teleportation node at that time, and it was also the military that lent him a transport plane, so that he could brush the task everywhere, and unblock the teleportation qualification as soon as possible.

Therefore, this time Chen Zhong found his head and asked him for help, and he quickly agreed.

"Among the commanders I can find, you are the most suitable person in terms of strength and communication conditions, so you are the only candidate for this battle. Chen Chong also made fun of Maude, and then officially stretched out his hand to Zhang Yide: "Thank you for your help." ”

Zhang Yide shook his hand: "What are we talking about between us, and besides, I also have needs." ”

"Well, this need of yours has been debated for a long time. Chen Zhong said expressionlessly, and now he feels a headache when he thinks of the previous meeting.

"Haha, let them have a headache, anyway, it's not your headache, you can't use this thing, right?" Zhang Yide smiled.

Chen Zhong shook his head: "You can't say that, it is also very good for us to get more californium." ”

The 'we' he said includes the free commanders, and if some bigwigs have a way to solve some of the current terminal diseases, then they won't be cranky and rush to the doctor.

Last time the Great Purge of Sky War Princess,Although some people with great ambitions have been washed away,But no matter who it is,,When facing death,There is now a big guy who has really been diagnosed with a terminal illness,Waiting for death。

This big guy is usually a person who is dedicated to the people, and many people don't want to see such a big guy die, and people like Chen Zhong are more worried that such a big man will take another path in the face of the death crisis.

What's more, even if this big guy keeps his heart and doesn't go another way, what about the other old friends around this big guy? What about the countless people who rely on him to eat behind this big guy? Will those people be willing to let this big guy die?

Moreover, who can guarantee that those people do not have the same idea in their hearts, wanting to develop a therapeutic device of the same level as the manufacturing chamber?

In short, after the last catastrophe, the current Chen Chong and the people behind him are very worried about a similar disaster happening again.

Now, the country can no longer afford such losses.

Zhang Yide looked at Chen Chong's face, and probably understood Chen Chong's difficulties, to be honest, prolonging life is what every human being yearns for, not that a group of people died, and the people behind were frightened.

Who isn't crazy in the face of death?

I'm going to die anyway, so why don't you fight before you die?

Zhang Yide can understand the psychology of these people very well, not to mention others, it is Zhang Yide himself, when he faces a terminal illness and has little time left, if he catches the opportunity to live, even he himself can't say whether he will die and grasp this life-saving straw.

"I see. Zhang Yide patted Chen Chong's shoulder and comforted: "Don't worry, I have a number, californium is not the only element that the United States can produce." ”

Needless to say, Chen Zhong had already understood the meaning of Zhang Yide's words, and the middle-aged uncle's eyes lit up, so he nodded and said, "Since you have a heart, that's good." ”

"Hmm. Zhang Yide didn't continue the topic, turned to look outside the house, and asked, "By the way, what are we going to do next, is someone coming to pick us up?"
