While Fang Qianmo set up his ambitions, Li Yu was patrolling the Pacific Ocean at this time.

Over the Pacific Equator, Li Yu in the Skyhawk was looking at the data fed back by the detector, looking for a suitable reef area.

Fang Qianmo once suggested that Li Yu could buy a suitable island. Anyway, many islands are being listed for sale abroad, but Li Yu rejected this suggestion.

This base set up in the sea is used as a base for the mage team to fight against aliens, so its confidentiality is very high. If you obtain the base by purchasing, it will always leave clues in the eyes of those who are interested, and perhaps one day it will be exposed to the world.

Li Yu’s idea was to build a base under the sea, so that it would be the most concealed, and it would not be possible to choose a place as the site of the base by simply choosing a place.

If the water is too deep, the inlet and exit of the spacecraft will definitely affect the surrounding waters. If it is not controlled properly, it is very likely to cause a small tsunami. It is not possible to have too shallow water. Reconnaissance satellites above the earth are flying all over the sky, and planes flying further down the sky are constantly flying. Maybe the base will be exposed unexpectedly at any time.

Li Yu is not planning to have too many advanced technologies in the base. In the design, the base is an energy shield, and in addition to the energy room, it is the take-off and landing area of ​​the spacecraft, as well as the maintenance area.

Li Yu is not prepared to set more functions, but he will leave enough space. At that time, the base people can add any needs.

In other words, Li Yu is preparing to let the base develop freely. Although the base personnel are positioned as combat mages at that time, Li Yu will not stifle their enthusiasm for research.

The enveloping range of the energy shield Li Yu designed the diameter of 100 kilometers. In this regard, this base is larger than Li Yu's laboratory.

With such a large base, the functions designed by Li Yu are far from filling the base, so the remaining space will be allowed to be played by the members of the base themselves.

The location of the base must also take into account the geological conditions. Overall, there are actually not many places suitable as bases in the ocean.

"Xiao Wei, record the position of this coordinate and list it as a secondary target."

"Okay, Li Yu! The conditions here are actually pretty good, why not choose this place?" Xiao Wei asked curiously.

"The water depth here is only 100 meters on average, which is not suitable. My ideal water depth condition is between 300 and 500 meters." Li Yu explained to Xiaowei.

"Since this place doesn't work, then let's go to the next target area?" Xiao Wei asked Li Yu for his opinion.

"Well, go to the next target!"

The Skyhawk flew quietly and reached its intended target in just five minutes.

This is the tenth goal that Li Yu came out to inspect. It is also one thousand kilometers away from the nearest island. In terms of the surrounding environment, it is extremely suitable as a base.

As the measurement data were summarized, Li Yu smiled on his face, "It seems that this place is more than enough as a base!"

No wonder Li Yu was happy. The average water depth of the target area was 400 meters, and the shallowest part was 350 meters. It was a rare smooth place in a reef area. The terrain was undulating and changed little, so a little transformation was the best base location.

When the final measurement diagram came out, Li Yu decided to put the base here.

This is the location of a sea-understorm mountain range, with an average water depth of 6,000 meters. Li Yu chose the place where the mountain ridge is located, which is an irregular square.

After Li Yu determined the site selection of the base, he began the construction of the base vigorously. The first thing he had to do was to set up the energy shield.

Li Yu finally developed the energy shield technology. Energy protection is essentially an energy field in a high energy state, which can of course be understood as a compression field formed by the electromagnetic field gathering somewhere.

The materials on the alien spacecraft have made a huge breakthrough in Li Yu's energy field research. The practical energy field can finally be put into use, and the base in the ocean is the first to be used.

Previously, the enterprise account also used a simple energy field technology. The technology has defects and is manifested as not being used for a long time. The protection threshold is very low, so it can be said that it has no use.

Strictly speaking, the energy shield technology that Li Yu has developed now is not the most mature technology. The most ideal energy shield technology should be the technology that can be adjusted at will, and the threshold value can be adjusted at will, but Li Yu has not yet been able to develop this technology.

In order to make the energy shield move, Li Yu must arrange carefully calculated nodes.

The position accuracy of the node's cloth cover is extremely high. After determining the position, the installation project is handed over to the intelligent robot. Underwater, the specially developed horizontal construction robot is not affected by the slightest seawater.

According to Li Yu's design drawings, dozens of robots began construction.

Li Yu was not idle either. He was modifying the laboratory drawings. The drawings designed by Li Yu had already considered the geological conditions in advance. The target area he chose was not much different from the design conditions, but it also required subtle adjustments.

The construction speed of the robot is very fast. After only three hours, the nodes were arranged. Li Yu personally went to the seabed to arrange the main control system and energy center of the energy shield.

The energy center is two dark energy reactors, and the main control system is an optical brain. The nodes have been connected by energy channels. When everything is in place, Li Yu returns to the Sky Eagle and then orders to activate the energy shield.

The dark energy reactor is normally started under the control of the main control system. The surging energy flows into the energy node along the energy channel. The energy node lights up at the same time, and then a slightly blue energy shield rises from the ground and closes at fifty meters away from the sea.

The energy shield looks a little blue, mainly due to the effect of sea water, and the expansion shield itself is colorless.

Next, what needs to be done is to empty the sea water in the shield. Through the several entrances and exits left specifically, the sea water was quickly drained, leaving only some remaining sea water in the depression.

After the seawater was discharged, what Li Yu had to do was level the ground, which was almost the same as the laboratory process in Tibet at that time. The difference was that the base occupied much larger area and had a large floor drop.

The leveling plan Li Yu did not choose the entire ground level, but divided the terrain into three levels according to the clever design of the drop. Li Yu is not short of engineering machines. After putting the required robots into construction, Li Yu returned to the laboratory. The next construction will take half a month according to the progress.

When he returned to the laboratory, Li Yu ignored Fang Qianmo, who was full of fighting spirit and focused on studying the second-generation spacecraft. Although Fang Qianmo told the country that the design of the second-generation spacecraft had been completed, it only determined the technical indicators. What Li Yu did next was to study each technology in detail.

When leaving the No. 001 factory, Li Yu ordered the construction of ten Skyhawks, but the order was cancelled when the alien spacecraft was discovered on Venus.

Li Yu is now studying the performance and manufacturing methods of alien spacecraft materials.

After Li Yu's detailed research, the materials used in the outer shell of the alien spacecraft are similar to his treatment of the materials. Li Yu's current alloy material with the best performance must be processed through a force field during the treatment process, which greatly reduces the atomic spacing of the alloy, thereby improving the performance of the alloy.

The main elements used by alien spacecraft are iron elements, but the atomic arrangement and spacing of iron elements are very different from normal iron elements.

The main element is iron. In addition to the above reasons, there are other elements in the alloy. The structure of one of the elements makes Li Yu extremely interesting because he does not conform to the laws of the periodic table of elements on the earth.

A long time ago, Li Yu discovered that there were other ways of expressing the existing periodic table of elements.

Since the Russian chemist Mendeleev invented the periodic table in 1869, there have been more than 170 periodic tables of various types. In summary, they mainly include: short form table (represented by Mendeleev), long form table (represented by Werner), specialty table (represented by Porta); plane spiral and circular table (represented by Damkev); three-dimensional period table (represented by Laith's conical column stereoscopic table), etc.

No matter how these forms change, they reflect two-dimensional content. There are only more than one hundred elements on the periodic table, and there are now 3,040 nuclides discovered in nature.

With the development of science and technology, humans have become more and more aware of nature and have discovered more and more elements. At first, the periodic table of elements became less and less able to meet people's needs, so various periodic tables were developed.

Li Yu deepened his research on elements, especially after fusing spatial runes, his understanding of elements became closer and closer to the essence. After summary, Li Yu believed that elements that have been formed can actually be added to the table of simultaneous elements in a three-dimensional way.

In this way, the format of the periodic table of elements will undergo huge changes. Li Yu is developing such periodic table of elements, but the progress is slow.

The discovery of alien spacecraft greatly promoted the development of this process. With actual evidence, Li Yu's materials science research has made great progress.

In the periodic table of elements, iron elements are divided into different elements. Their chemical properties are not much different, but their physical properties are different.
