As the major legions of the Yanhuang Empire entered the human realm one after another to cultivate, the news of the skyrocketing spiritual energy concentration in the human realm soon spread throughout the Yanhuang Empire, and countless people were shocked.

The human realm suddenly became what people called the human fairy realm, a holy place for cultivation. Countless cultivators are fanatical about it, wanting to enter this human realm and start their own demonic lives.

For a time, the conscription offices in the major cities of the Yanhuang Empire became crowded.

Everyone wanted to follow a legion of the empire and enter the human realm that was said to have ten times the aura of the Four Directions Continent to further study.

And this is what Su Yu had thought of a long time ago, he issued an edict as early as the second day when the aura of the human world skyrocketed, raising the threshold for conscription.

Originally, you only needed to realize the true realm to join the army, but now the requirements have been raised to Nirvana nine turns or above. The number of recruits was limited to five million,

From the very beginning, Su Yu gave a definition to the human world, the world that belongs to the elite of the Yanhuang Empire, the cradle of the future main force of the Imperial Legion, is naturally not something that ordinary people can enter if they want to.

If we don't set a higher threshold for the human realm, the human world will be crowded by these fanatical people of the Four Continents, which will cause all kinds of riots.

And although Su Yu's general threshold was much higher, the number of recruits still reached the upper limit of the number of recruits in two days, five million.

Coupled with the original number of the major legions of the Yanhuang Empire, the number of warriors who poured into the human realm at one time was as high as 25 million.

And settling these two five million elites also made Su Yu spend a lot of energy, and he built a huge city outside the existing six cities in the human realm, and attacked the city.

The size of the garrison was twice as large as the other six cities combined, barely enough to accommodate all 25 million warriors.

Although he was a little tired in order to settle these warriors, Su Yu was still somewhat relieved to see these two five million warriors whose strength was above the ninth turn of Nirvana rapidly becoming stronger in the human realm.

Twenty-five million Nirvana Nine Turns, after cultivating in the human realm for a year, it is estimated that all of them can reach the lower legendary realm.

"Tsk. Su Yu felt perverted when he thought about it.

Twenty-five million Legendary Realm powerhouses were enough to match the number of medium-strong people who were famous in the Endless Star Sea, which was something he had never dared to think of before.

It took Su Yu a full week to settle these warriors. In the past week, there has been a lot of good news from the scientific research city and the manufacturing city.

After receiving Su Yu's encouragement, the young man who developed the laser cannon worked non-stop, day and night, to complete all aspects of the laser cannon in five days.

And Zhuge Liang not only installed the laser cannon on the lightspeed spaceship according to Su Yu's order, but also placed the laser cannon on the tank developed before, replacing the main gun on the original tank.

As a result, the tank, which was once declining in role, now has new combat effectiveness, and the tank corps will once again become a heavy weapon on the battlefield.

This made Su Yu have to praise Zhuge Liang a lot.

Jiang is still old and spicy, although Zhuge Liang has not made much contribution to the laser cannon, but he will make full use of this research result.

And just when Su Yu was about to leave, Zhuge Liang stopped Su Yu.

"Emperor, please stay. Zhuge Liang temporarily remembered something.

"What's wrong? What else do you want to tell me?"

Zhuge Liang took out two lumpy metals from the space ring, placed them in his left and right hands, and said.

"A handyman found this ore in a pit, and the ore that had just been found was dark green and fluoresced strongly under the light of the purple light. And it exudes some unknown energy. ”

Fluoresce under violet light?

Su Yu's mind flashed a mineral from the textbook of his previous life.

"Could it be...... So possible. Su Yu smiled bitterly and denied what he was thinking.

It stands to reason that it shouldn't be that horrible thing.

Zhuge Liang continued.

Chen felt that this mineral was a bit weird, and it was extremely difficult to refine it with the normal equipment of the Scientific Research City, so he asked the guards of the Scientific Research City to refine this mineral with Gang Qi. ”

"After the refining is completed, these two pieces of metal are in the hands of the minister. Zhuge Liang gently raised the lump metal in his hand and continued, "After this mineral is refined, the energy emitted is becoming more and more intense, and it has a certain amount of harm to ordinary people. ”

"What's more, if the two pieces of metal collide, they will explode. ”

As soon as Zhuge Liang finished speaking, Su Yu was stunned, looking at the metal in Zhuge Liang's hand, speechless.

Isn't this the core uranium of nuclear weapons in the previous life!

Dare to love such a thing in this human world!

It was found in the thatched pit in the toilet of the Scientific Research City!

A series of exclamation marks appeared in Su Yu's mind, and sure enough, everyone in the scientific research city was a demon, even the miscellaneous servants.

He has been completely conquered by the demons of the Research City.

This is also due to the fact that the scientific research institute has already mastered the nuclear bomb system, otherwise if people know that the core element of the nuclear bomb system of the Yanhuang Empire is found by a miscellaneous servant from the toilet......

Su Yu smiled a little bitterly, I'm afraid that the coffin board of those great people in the previous life can't be suppressed!

"Emperor?" Zhuge Liang looked at Su Yu's reaction and called cautiously.

Only then did Su Yu come back to his senses, his face was red for a while and white for a while. I couldn't tell if it was a surprise or a shock.

"Study it well, study it in the direction of the internal reaction of the ore! I will let the department in charge of minerals look for this mineral." This mineral will be called uranium in the future. Su Yu finally stabilized his mood and led the way for Zhuge Liang.

He didn't know much about uranium, so he could only help Zhuge Liang get here.

Uranium is a rare metal and one of the key elements in the manufacture of nuclear bombs, but this does not mean that scientific research institutes that have mastered nuclear fission technology do not need to continue to study uranium. If the shaft is used properly, it is still very useful!

Axis is used in industry to realize automatic production control and non-damage inspection, in agriculture to use radiation to cultivate improved seeds, to prevent pests and diseases, etc., in medicine for sterilization and disinfection, clinical diagnosis and treatment, in geological exploration work to find minerals and so on.

It can be said that the advent of each new rare metal represents a new improvement in Imperial technology.

Hearing Su Yu's words, Zhuge Liang nodded thoughtfully, and then left respectfully.

And Su Yu left this place with emotion.

He still didn't pay much attention to this matter for the time being, but he was a little speechless about the process of discovering uranium in the scientific research city. The properties of uranium have just been discovered in the Science City, and it will take some time before the uranium element is fully utilized.

It didn't take long for Su Yu to come to Manufacturing City.

He personally improved a lot in all aspects, and handed over the drawings of the second-generation tank with the main gun to the manufacturing city to ask them to start manufacturing, and by the way, he also looked at the latest progress in the manufacturing city.

In the short space of a week, another huge troop carrier was built in the manufacturing city.

One troop carrier can accommodate a million fighters.

To date, the city has built a total of six troop carriers capable of carrying six million soldiers.

Su Yu nodded in satisfaction.

The focus of the attack on the Longshan Continent is still those thirteen saints, and six million warriors are enough to sweep away other enemies except those thirteen saints.

The soldiers of the Blade Force are still working hard as ever to cooperate and have various battlefield abilities.

And the students in the Yanhuang Martial Arts School all studied hard and cultivated.

Everything in the human world is developing at a high speed and in an orderly manner. Everything seemed to be peaceful, but Su Yu knew that it was just the eve of the storm.
