Some of the industrial equipment in the underground space was in full operation, and the silent laboratory was also running at full power after Ivan moved in.

A technology often needs the support of an entire industrial system.

Fortunately, the people who built this kind of civilization vault have taken this into consideration. There is a perpetual motion machine underground that can provide power for more than three thousand years and a large piece of industrial equipment.

Ivan, who has perfected space technology, first made several small sets of space equipment to practice his hands, and experimented with the space recovery function of the Spear of Thorns later.

Two of the good spatial warehouses were given to Li He and Xiao Luo when Li He was about to leave.

The two space warehouses are both wrist guards. The volume is not very large, but it is not too small. It is a small space of 5 by 5 by 5. However, just these two successful spatial warehouses consume a lot of precious materials.

Space equipment is extremely treasured no matter which civilization it is in.

It was Lee Hyuk who saw Victor the last time, and Victor did entrust Lee Hyuk with a heavy responsibility. If it weren’t for Lee Hyuk's strong opposition to me, Valkyria would take the Salvation Crusaders and swear to Lee Hyuk like Ivan. Allegiance.

Now the Holy War of Salvation, including the lieutenant, Valkyria, is also under Li Hyuk's command.

"Your Excellency, haven't you noticed that the sword in your hand is very special?" Valkyria said.

"What's special?" Li He asked, looking at the sword in his hand.

"Some shadows of the heart of steel." Valkyria said.

"Yes, my lord, there are indeed some shadows of the Heart of Steel. No, to be precise, this is an upgraded version of the Heart of Steel. After all, the Heart of Steel is an antique, whether it is material, function, or embodied on the sword. Craftsmanship, the heart of steel in the holy city cannot be compared to your invincibility, my lord."

Old Ivan said cherishedly.

Li He was speechless. On the surface, he said it was a fair deal, but in fact, he was scammed by that guy unknowingly.

This is all right, because this sword shaped like a heart of steel, the people of the Salvation Crusaders actually depend on themselves.

And Li He still had to clean up this mess. After all, the power of the resistance was scarce, and nothing was precious.

With the space warehouse dedicated to him by the old Ivan on his wrist, Li He straightened his white robe, which was a bit ostentatious.

Li He threw Victor's third into the space warehouse. The benefits of space equipment are immediately revealed, and it is much more convenient with it. And because the space warehouse is forcibly tore off a space that has no time to flow in a similar plane, and then forcibly seals this unstable space in some special materials, so that this space is stabilized, and then a stable space is solidified. Open and close the program, this is a spatial warehouse.

Because all the things stored in the spatial warehouse are placed in a stable and similar plane, even if this thing is filled with him, his weight in this world will not increase by a bit. Moreover, some obvious features are hidden inside, which saves the risk of exposure and can save a lot of trouble. Even if you find it, the overall defense of the underground space is amazing, and there are layers of defenses that separate every area. That is a vault in civilization. If it is breached so easily, what is it called a vault?

"I'm going to the Holy City to do some things." Li He said.

The place where Victor was resurrected was in the holy city, and I don’t know how it would be resurrected.

But it is certain that Victor, who is weak in the Holy City, must need help. Li He also needs to continue trading with him, and arm himself as soon as possible with the knowledge and power of this civilization, so that he will be able to fight against Karl Suther in the future.

"What about the Salvation Crusaders, my lord?" Ivan and Valkyria asked at the same time.

"Stay here for now." Because I ate two first-level battle groups in an instant, I wouldn't be stupid enough to continue to want to send it here if I can't figure out what is going on here in the Holy City. Human head.

"By the way, Xiao Luo gave me the map." Li He reached out his hand and took a steel plate with dense patterns, which is actually composed of a series of passages.

"This is the overall map of the underground space. If someone comes, you can fight if you can't fight, but if you can't fight, you will be a little bit tricky, and hide deep underground. At a depth of a few hundred meters, even some super units may not necessarily find you." Li He handed the map to the two and said.

"Counsel...well, sir, if we need our strength, sir, please do not be polite." Valkyria said. How did the Jihadist Salvation Army survive so many years? It's not just trying to survive, but even more daunting. It is estimated that no one can beat these rebels.

"Relax, complete the transformation of the thorn weapon system as soon as possible. You will be required to play sooner or later." Li He waved his hand and said.

"Following in the footsteps of adults is my glory."

There was a word from Li He in the wind.

"Remember my promise, Ivan, if you understand the meaning of that word, I will help you become a god."

That word?

Ivan flipped through all the books in the underground space library like crazy, and even used a computer, but he couldn't even find the shadow of that word.

Out of absolute trust in Li He, Ivan did not have any doubts, but in addition to the experiment, he put his limited energy into the history and literature of Zuan with infinite enthusiasm.

Valkyria is already a god, at least he can't fall too much. Ivan looked at Valkyria and thought.

"Let's go, let's go back."

Valkyria took Ivan's arm and said.

"Wait, let me check the piranhas in the river." Ivan said.

"Vice general, lead someone to protect Your Excellency Ivan."

"Yes, sir." The lieutenant took a few people and carried out a small boat from the inner city.

The boat was put into the water, and Ivan, like his instructor, went to fish in the river. Valkyria watched from the shore, pulling out his spear and rubbing it lightly, while waiting quietly.

A figure with huge wings fell from the sky, and a beautiful mechanical girl came out of his arms.

The two stood on the horizon, looking at the huge city in the distance and exclaimed.

"Master, it's so big."

"Well, it's really big."

The holy city of Zuanxing is far more magnificent than any city in earth civilization.

If we have to say it, then the ancient temples of the earth civilization Shenhe period are comparable to each other.

Zu'an civilization is not open-minded, but sometimes feudal civilization can produce miracles one after another.
