Twenty days later, when Changying Group was holding more than 100 mineral resources and nearly 10,000 tons of various rare metal resources in its hands, Lin Dong also went into seclusion. .

Although Lin Tianfeng is not there, this time, Lin Dong's workload has been greatly reduced with several smart robots left by Lin Tianfeng.

As some people in Changying Group speculated, this time he designed the entire earth's defense system.

Compared with the previous aerospace planes and even space stations, the earth's defense system is larger in scale and has more advanced technology. Without the help of four robots, Lin Dong himself would probably take more than a year to complete the "replication and development" of the entire technology.

However, this speed is obviously not good. I wonder if it is the butterfly effect caused by the encyclopedia in his mind. The wreckage of alien UFOs that should have appeared many years later has now appeared in the solar system. So, will the day when real alien flying objects appear still be far away?

It would be fine if Lin Dong didn't know about this. Once he knew about this, he could do something within his ability. If he didn't do it, his conscience would definitely be uneasy.

If you can't do it, you can't ignore it no matter what.

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

After leaving the office, Lin Dong only took a day off and then devoted himself to the next work. He first classified all the resources he exchanged during this period, first and then slowly separated, and then called all the senior executives of the sub-groups of Changying Group together for a meeting!

When Lin Dong called for a meeting, this time was not as dull as the last time. Everyone was very excited, except Lai Tongguang, everyone knew that once Lin Dong was "in seclusion", he would definitely start to divide the tasks and cakes. As long as Lin Dong took out the skills, no one would be unsuccessful and would not cause a sensation!

When the staff arrived, Lin Dong asked the secretary to distribute the information he had printed long ago and the hard drives to the bosses of each group, and then explained:

"In the next year, your current production and research tasks will be placed at a secondary level. The main energy will be used to familiarize yourself with the technology I gave you and to carry out production. Of course, your production tasks are different, including production equipment, mineral refining, and precision processing machines. In general, in the next year, our main job will be to produce the core part of the earth's defense system. Lao He, your focus is to contact some of the remaining non-core components for processing and production. The price is secondly, the focus is on production efficiency!"

Although the current production tasks are placed at a secondary level, it means that the group's money-making speed will slow down, but no boss has any objections. No matter how big the money-making matter is, it must have a safe environment to make money. If the earth is really invaded, then that's all that money?

Although the chance of such a thing is relatively small, there is always this chance, right?

After assigning the task, Lin Dong immediately disbanded the meeting and went on the next task.

He went to Tengjiao Group.

As usual, what Tengjiao Group wants to do is to produce the foundation and main weapon system of the earth's defense system. As a super-large extraterrestrial flying object, this earth's defense system is based on three large kinetic energy attack systems that operate along with the earth in geosynchronous orbits. The scale of each kinetic energy attack system is much larger than the largest extraterrestrial flying object now. Such extraterrestrial flying object cannot operate only by the gravity of the geosynchronous orbit, but also requires extremely energy-driven.

After receiving the information, Tan Judong quickly returned to Tengjiao Group. At this time, Xu Xiaofeng was discharged from the hospital and conducted his research in Tengjiao Group. After seeing the information, he looked puzzled: "A guy with such a big kinetic energy is difficult to solve! It is the largest scale in our flower planting batteries. I am afraid that many groups will be needed to drive..."

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

Specifically, Lin Dong did not explain. Xu Xiaofeng was also tactful and did not ask.

Two months later, when Tengjiao Group produced almost the same frame for the defense system, two aerospace planes quietly landed on Tengjiao Group.

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

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

"It looks like it, but the contents are too different." Lin Dong waved his hand: "This will be the new energy-use basic energy crystal for our Changying Group in the future. This piece of energy crystal as big as a palm can drive an aircraft carrier to operate for more than a few years!"

It is indeed much more energy than nuclear fuel!

Xu Xiaofeng's mouth opened his head, and it was too sci-fi to fail to close the energy crystals until they were transported away!

There are still a steady stream of companies to exchange technology for Changying Group. In the eyes of many people, the threat of aliens is too far away, and the benefits you get is the most normal. Changying Group's technology is already the best in the world. Although it is only for technical authorization, this is enough. Even if you can't eat meat or chew bones, can you drink some soup?

Just as the prosperous exchange and silent mining and production process, a year passed quietly.

Tengjiao Group.

All the senior executives of Changying Group are here.

Five airplanes that are larger, more weird and more sci-fi are lined up. Compared with the Donghuang, these airplanes have a more impactful feeling. They have a weapon system that comes out of the front on the nose, which looks very deterrent.

Of course, what is more important is that they are larger, not only useful in combat, but also have a greater transportation effect.

Without bold words, Lin Dong waved his hand and five aerospace planes flew straight into the sky, instantly becoming a small black dot Xingtian aerospace plane equipped with a new engine and energy crystal not only has strong kinetic energy, but also has strong weapon systems. It is an advanced space combat transport aircraft.

Three days later, Changying Group suddenly announced in a high-profile manner that the earth's defense system has been successfully assembled and will conduct experimental shooting of an asteroid that is about to fly in a week to test the performance of the defense system!

Only once the announcement was released, the world was shocked!

Changying Group actually completed the assembly and launch of the entire earth defense system in a quiet process. Everyone thought that Changying Group was still accumulating resources!
Chapter completed!
