Lin Dong didn't think too much about Jiang Hongwei's happiness. He directly asked He Dongcheng to come again in China, and then sent a group of mining personnel in the front to mine the metal Taihe Gold Mine at the same time. The pressure on the personnel was a little too high.

Of course, the people who asked for this time were very active. Because two of the employees were hit by stray bullets, they went back to China to recuperate, but they were treated with five-digit medical expenses, bonuses and full salary!

The other injured security team members also have full paid rest. This time, as long as the security guards who participated in the battle, the reserve team members who actively applied for, and the stretcher team members, each person will receive a reward of 10,000 yuan, and those who perform well will be double or even three copies!

After the news of such a high bonus reached the country, many of those who did not come regretted it. They just walked around the battlefield and received such good treatment. Who doesn’t want to go? Besides, in order to set a model, Changying Group directly took a lot of photos and sent it back to the country, and promoted the security team members and mining personnel who performed heroes during the battle. For this reason, they also held a special celebration meeting, which made those who did not come envious!

"Mr. Lin, this is the first batch of metal powder!"

A series of mining processes were originally very water-consuming projects. Afghanistan is very short of water, especially in the area where Lin Dong was looking for, and it is very difficult to find a suitable water source.

Even the drinking water in the camp was found by digging wells. However, the small water source needs to be supplied to tens of thousands of people to drink, and it is not very abundant. Fortunately, there is underground water source in deeper underground places. Lin Dong lacks anything, but there is no shortage of machinery. There is no problem with digging wells, and the water quality is good.

But if this water is used for mining ore dressing, it will be a bit difficult.

Of course, this is not difficult for Lin Dong. Dysfunctional ore dressing is really not a big deal for Lin Dong. However, the forming is not a metal block, but a metal powder. And the purity is not very high.

Of course, this is actually enough. These metal powders will be sent back to the country and then deep-processed to form metal ingots, and then sent to the metallurgical factory to process into the required alloy for further processing.

Lin Dong looked at the metal powder sent by Xia Guangcheng, which was different from the metal ingots formed in his memory. The metal powder was covered with a little silver ash, but he immediately "recognized" it. This was indeed the metal called Zhu that he was looking for this time! Zhu's interpretation in Chinese characters was originally very small, so there would be idioms that were full of slight considerations.

However, the Zhu here refers to the current metal that seems gray and white, but is actually bright white, and its content on the earth is very small, which is one of the reasons why it is named with the word "zhu".

However, this is what makes nature amazing. Although there are very few ore of this metal in any other place in the world, there is such a very high-quality ore in Afghanistan.

Just like the metal rhenium mentioned above, there is no pure metal ore in the world. However, later, metal rhenium appeared on the four northern islands and later on the South China Sea. This was what Lin Dong told Ji Bing. It should have been discovered more than ten years later.

The characteristics of this metal slurry are relatively obvious, which are resistant to high temperature and high pressure and corrosion. It uses slurry to form a coating on the surface of the metal and can resist the erosion of various cosmic rays. It is a very excellent space material.

Because it is a later metal, it has not been applied yet. If Lin Dong had not had this information in his mind, he would not have found this mine here.

In parallel space, this mine was discovered by French geologists, but due to geographical reasons, the ownership of this mine was finally given to the United States. China still paid a high price to buy a very small portion of metal from the United States. This metal is quite a lot in the asteroid belt, but there were no large mines on Earth until many years later.

Of course, Lin Dong doesn’t care about so many things in this life. There are so many good things on the earth, and there are so many good things occupied by the United States. Lin Dong has no psychological burden to do such things as intercepting the truth!

Trucks of supplies were taken to the camp, and a considerable number of them were sent to the Taha tribe, which allowed the elders of the Taha tribe to truly understand the trustworthiness of the Changying Group.

And the day after the Taha tribe obtained the road construction permit, Lin Dong began to purchase materials, bidding for construction teams and application for various procedures through Changying Group. Because it was a special matter, within a month, the first truck of materials for the road construction had been pulled to the port, preparing to pass the customs and start road construction!

With the architectural level of China, you can imagine that this asphalt road of hundreds of kilometers may not be fully connected in a long time!

Lin Dong did not wait until the entire line was completed and stayed in the camp for half a year. He returned with the first group of security personnel and mining employees who had changed defense. Their return was about ten tons of metal baht powder that had been initially processed.

According to Lin Dong's calculations, these roughly processed metal baht can eventually get about five tons of metal baht. However, even these five tons, as of now, the most important function of Changying Group's 10-year-old stake is to process it into alloys and then apply it to spacecraft. Pure metals cannot fully reflect their role.

In the operating room of Tengjiao Group, Xu Xiaofeng looked depressed: "I have clearly tried all the data in the research room, but once the simulation experiment is reached, it cannot withstand radiation and high temperatures. The existing materials have almost been tried. Do you have to wait until Mr. Lin comes back?"

Now, under the guidance of Liu Zongyi, he has successfully completed the motive manufacturing of the small aircraft and passed the verification and has been successfully applied on a domestically produced small aircraft.

But Xu Xiaofeng was obviously not satisfied. Now that Changying Group has given him such great support, he has a stronger idea of ​​studying space motivation.

However, although space motivation is not a particularly science fiction technology now, it is very difficult to find motivational materials that require high temperature, high pressure, corrosion resistance and freely shuttle back and forth in the sky.

Xu Xiaofeng has tested a lot of materials, and there are always problems of one kind or another.

Space motivation is indeed not that easy to study!

Nowadays, China, the United States and the Russians have corresponding technologies, but the confidentiality of the technology is equivalent to the core secrets of the country. In Xu Xiaofeng's opinion, these technologies are not very perfect, and are only used on large detectors, space shuttles and space stations, and do not meet the technology he requires to apply on space shuttles.

I have to keep working hard!
