After Lei Tiantang finished the introduction of the products, under the arrangement of the host, the reporters could not wait to start asking questions. After all, Lei Tiantang's family can now produce high-quality graphene on a large scale. We all know the meaning of this.

"Mr. Lei, does your production of graphene mean that your company will monopolize the market of high-quality graphene?" The first question is tricky.

Lei Tiantang said with a smile, "how can it be? There are many graphene manufacturers on the market, but our technical level is a little higher. I also welcome you to compete with our company through industrial upgrading, so there is no monopoly! "

"We all know that high-tech products will be restricted in some countries. Will you restrict the sale of high-quality graphene?"

"As I said before, I am not afraid that others will compete with us. Only when the graphene market becomes bigger can I sell more products, so I will not restrict the sale of our products for the time being."

Lei Tiantang also answered the reporters' questions one by one, and then led the reporters to change their dust-proof clothes and began to visit the factory. Lei Tiantang was not afraid that their photos would reveal any secrets. Anyway, the most important equipment was made by him. Even if people knew the specific situation, they could not produce it.

Because they can't pass the test of ultra-high strength materials, Lei Tiantang has not applied for a patent for the equipment, which means that even if the design scheme is known by others, they can only stare at it.

Reporters are also very curious about the factory, so as soon as they come in, they all hold up their cameras and cameras and start shooting from various angles. It's hard to say that there are no part-time commercial spies, because there are a lot of people who pay attention to their company. Lei Tiantang himself has found that there are sneaky places nearby, but Lei Tiantang has not taken care of them for the time being They can't find anything useful. If they keep fishing, there may be some surprise.

The press conference was very successful. Although Lei Tiantang also arranged for people to entertain these reporters, none of them would like to stay for dinner because they wanted to go back and send out the news at the first time. Now we all know the timeliness of the news. If we delay for a long time, the news may become old news.

In the next few days, Lei Tiantang made headlines again. Yang Ma reported him for more than one minute in the news at 7 o'clock every night. After all, this was another breakthrough in the field of science and technology in China.

All kinds of orders, large and small, also swarmed in. Although the company's pricing for graphene was not low, it did not stop these companies and laboratories from purchasing, because we all know very well that if we lag behind at this time, we will not be able to make money.

The factory is also fully engaged in production, these things Lei Tiantang just know about it and then give them to Tian Mingli. He's going to be busy with his own business.

His private laboratory is now almost decorated, waiting for equipment procurement to come back and install, and he will also start the construction of his own underground laboratory.

For him, it is not difficult to excavate the laboratory. He has already planned the standards of the laboratory, so there is nothing to prepare now.

In the evening, he flew back to the company directly from home, and began to dig down from the elevator shaft on the second floor underground of the laboratory. There was no earthwork to deal with, because Lei Tiantang directly used absolute field to press the soil layer from fluffy state to more compact state, and the walls were stronger than those poured with concrete.

It took a short time for Lei Tiantang to deal with the channel 1000 meters down. This range is under his absolute control, so it is very simple to handle. Then he took the processed high-strength alloy from the storage space, and used these high-strength alloys to reinforce the four walls of the passage, although he was not afraid that the walls he handled would collapse, But it's not better to have less trouble. Anyway, the reinforcement work is also very simple, and the opening and hanging are of course easy.

After the passage was finished, he floated down happily. Although there was no light and could not be seen by the naked eye, he opened the absolute field and saw the underground situation clearly in the sea. He did not have any claustrophobia and other reactions. After coming down, he directly started the excavation work of the underground laboratory.

For him, digging an underground space is very simple. It was the same as before. It directly compressed the soil layer, and then made several supporting columns with high-strength alloy in the middle to support them up and down. He had designed them, so they were built very quickly. After excavating the space, he strengthened the whole laboratory with a meter thick high-strength alloy, which was strong enough to withstand any risk, even the largest earthquake and other disasters would not affect the laboratory.

Lei Tiantang temporarily divided the underground laboratory into three floors. The temporary area of each floor was 1000 meters square. This area was enough for him to use in advance. In any case, if there was not enough space in the future, it would be very simple to expand.

The height of each floor has reached a height of 20 meters, which is enough for him to carry out any experiment. The reason why he designed this high is because it is too simple to open and hang, and when the height is high, he will not feel depressed when he is experimenting underground.It took him less than half an hour to finish the three-layer space. If people knew about this speed, it would be crazy. If the excavation of such a large underground space was carried out normally, it would take at least one or two years. Moreover, it would not be possible to build such a large space as Lei Tiantang, because the construction is so difficult.

To tell you the truth, Lei Tiantang had all kinds of ideas in his early design. For example, the honeycomb laboratory in the science fiction film "biochemical crisis" was very cool. He also wanted to build one according to that design. However, these plans were rejected by him because they were not practical, and he used the underground laboratory alone for the time being Those fancy things were not appreciated, so finally decided to make a square space directly, if you want to change in the future is also convenient.

It's not just a matter of digging out space. After all, it's used for various experiments, so we need to plan things like wastewater treatment, vent setting and so on. After the completion of the construction of these channels, nearly two hours have passed. Of course, these channels have been reinforced with high-strength alloy.
