Twenty days later, when Changying Group held more than 100 mineral resources and nearly 10,000 tons of various rare metal resources in its hands, Lin Dong also came out of retreat.

Although Lin Tianfeng was not there, this time there were a few smart robots left by Lin Tianfeng, and Lin Dong's workload was greatly reduced.

As some in the Changying Group speculated, this time he was designing the entire Earth Defense System.

Compared with the previous aerospace aircraft and even the space station, the earth defense system is larger in scale and more advanced in technology, and if there is no help from the four robots, Lin Dong alone is afraid that it will take more than a year to complete the "replication and research and development" of the entire technology.

But this speed is obviously not going to work. I don't know if it's the butterfly effect caused by the appearance of this encyclopedia in his mind, the wreckage of an alien UFO that should have appeared many years later has now appeared in the solar system, so will the day when the real alien flying object appear far away?

If Lin Dong didn't know about this matter, it would be fine. Once he knows this, he can do what he can, and if he doesn't do it, then his conscience will definitely be disturbed.

It can't be done, and it can't be ignored anyway.

Fortunately, it's not that difficult now. He is not alone now, and the thick foundation of Changying Group is enough for him to do things well enough.

Coming out of the office, Lin Dong only had a day off before devoting himself to the next job. He first classified all the resources exchanged during this time, first urgently and then slowly, and then called all the senior executives of the subordinate subgroups of Changying Group together for a meeting!

As soon as Lin Dong called for a meeting, this time it was not as dull as the last time, everyone was very excited, except for Lai Tongguang, everyone else knew that once Lin Dong came out of "retreat", then it was definitely time to start dividing tasks and cakes. As long as Lin Dong came up with the technology, none of them would be unsuccessful or cause a sensation!

When the personnel arrived, Lin Dong asked the secretary to distribute the printed materials and hard disks to the CEOs of each group, and then explained:

"For the next year, your current production research tasks will be relegated to a secondary position, and the main energy will be used to familiarize yourself with the technology I have given you, and to carry out production. Of course, your production tasks are different, there are production equipment, there are mineral refining machines, there are precision processing machines, in general, in the coming year, our main work is to produce the core part of the earth defense system. And Lao He, the focus of your work is to contact some of the remaining non-core components with domestic and foreign manufacturers for processing and production. Price comes second, and the focus is on production efficiency! ”

Although it is necessary to put the current production task in a secondary position, which indicates that the speed of the group's profit will slow down, no boss has any objection. No matter how big it is to make money, it must have a safe environment to make money. If the earth is really invaded, then it will make a lot of money?

It's a small chance of something like this, but there's always a chance, isn't it?

After assigning the task and leaving no one behind, Lin Dong immediately dismissed the meeting and moved on to the next task.

He went to Tengjiao Group.

As usual, what Tengjiao Group wants to do is to produce the base frame and main weapon system of the Earth Defense System. As a super-large extraterrestrial flying object, this Earth Defense System is based on three large kinetic attack systems that orbit with the Earth in geosynchronous orbit. Each kinetic attack system is much larger than the space station, the largest extraterrestrial vehicle available today. Such extraterrestrial flying objects cannot only operate by the gravitational pull of geosynchronous orbit, but also need to be driven by great energy.

After Tan Judong got the information, he quickly returned to Tengjiao Group. At this time, Xu Xiaofeng had been discharged from the hospital and conducted his research in Tengjiao Group, and after seeing the information, he looked puzzled: "Such a big guy, the kinetic energy is not easy to solve!" It's the largest scale of our flower planting batteries, and I'm afraid it will take many groups to drive ......."

When this question was handed over to Lin Dong, Lin Dong only said one sentence: "No battery, use a new drive engine energy crystal!" ”

Specifically, Lin Dong did not explain. Xu Xiaofeng didn't ask.

Two months later, when the Tengjiao Group produced the base frame of the defense system, two aerospace planes quietly landed in the Tengjiao Group.

Dozens of huge boxes were moved by robots into a secret workshop.

Looking at the neatly cut transparent spars in an open box in front of him, Xu Xiaofeng was puzzled: "Isn't this crystal?" ”

"It looks like it, but the content is too different." Lin Dong waved his hand: "This will be our Changying Group's new energy application foundation energy spar in the future." This palm-sized piece of energy spar can drive an aircraft carrier to run for more than several years! ”

Sure enough, it's much more energy than nuclear fuel!

Xu Xiaofeng's mouth was open, until all these energy crystals were transported away, and he couldn't close it, which is too sci-fi!

There is still an endless stream of companies that come to Changying Group to exchange technology. In the eyes of many people, the threat of aliens is too far away, and it is the most normal to get the benefits. Changying Group's technology is already the best in the world. Although the exchange is only for the authorized use of technology, this is enough, even if you can't eat meat or gnaw bones, it's okay to drink some soup, right?

In this booming exchange and silent mining and production process, a year has passed quietly.

Tengjiao Group.

The senior management of Changying Group is all here.

Five larger, weirder, and more sci-fi aerospace planes than the Donghuang are lined up, and these aerospace planes are more impactful than the Donghuang, and they have a forward-exiting weapon system on the nose, which looks very deterrent.

Of course, what is more important is that they are larger, not only for combat use, but also for greater transportation.

Without rhetoric, Lin Dong waved his hand, and the five aerospace planes flew straight into the sky, instantly becoming a small black dot The Xingtian aerospace plane with a new engine and energy spar installed not only has strong kinetic energy, but also has a powerful weapon system, and is an advanced space combat transport aircraft.

Three days later, Changying Group suddenly announced in a high-profile manner: The Earth Defense System has been successfully assembled, and will conduct an experimental shooting on an upcoming asteroid a week later to test the performance of the defense system!

As soon as the announcement came out, the world was shocked!

Changying Group actually completed the assembly and launch of the entire earth defense system in a silent process, and everyone thought that Changying Group was still in the stage of accumulating resources!

This efficiency is heaven-high!
