Maybe it's because it's dark under the light, or maybe it's because the Ye family thinks that Mercury is just a private garden for them to relax. Anyway, the supervision on Mercury is not strict and there are many loopholes to exploit.

After Zhang Yuan and Lu Meng came down from the airship, Zhang Yuan opened his eyes of insight and looked for a place where he could safely create a new mecha.

As he searched, Zhang Yuan found a natural cave.

The entrance to the cave is very large, more than 5 meters high. Once you enter, you will find a place similar to observation. There are some traces left by tourists in the corner.

Zhang Yuan walked in front, Lu Meng followed closely, and the two walked in the passage one after another. The passage became narrower and darker, and in the end, they could only let one person lean over and crawl through.

"Zhang Yuan, can this place work?" Lu Meng asked in a low voice.

"No problem, follow me closely." Zhang Yuan said confidently.

The two continued to move forward and walked along the winding passage for a full 3 kilometers. Many of them were unpassable to ordinary people. The two were able to continue to pass through with their strong physical fitness and some high-tech equipment.

At this time, they probably had already penetrated more than 500 meters deep. The passage became slightly wider, and the sound of dripping water from time to time came from around them, but the environment was still extremely dark. Even though both of them were holding lighting sticks in their hands, they still felt very dark around them.

"It's time to go further." Zhang Yuan whispered.

After walking forward for about 200 meters, the passage suddenly became very wide. You could still hear the sound of running water and the sound of wind. When the footsteps were stepping on the ground, you could clearly hear the echo.

"Click~"

Zhang Yuan lit up a lighting balloon, and the soft and bright light immediately filled the entire underground space. This space is more than 200 square meters and more than 10 meters high. The ground is flat and dry. There is also a clear stream near the stone wall.

"The rocks around this cave contain thin natural spiritual rough stones, which have no mining value, but can withstand the rhodium magnetic detection light of the sky satellite. At the same time, standing in a specific position, you see, here is this small circle less than 2 meters. The mental field interference in this area is slightly weak. Standing here, we can maintain communication with the outside world, but it may also be detected by the outside world."

Zhang Yuan used red paint to draw a small circle on the ground and wrote the words "Communication Area".

"As for other places, it is a complete blind spot. In this place, we can do anything without worrying about being discovered by the empire."

Lu Meng looked at the big underground cave and smiled and said, "No one interferes with or peeks at it. It's such a paradise."

Zhang Yuan laughed: "It's not something I found for a paradise, but it was created by myself. Look at the Ye family, the entire Birch Shuixing is their back garden. They do whatever they want, and no one cares about it."

Lu Meng spread his hands and said helplessly: "They are nobles, born with authority."

"Are you noble?" Lu Meng's expression made Zhang Yuan's heart slightly move, and he asked: "Why can civilians become nobles so pessimistic? As far as I know, joining the army and accumulating enough military merits can be awarded a medal."

This is what Xia Xiyan told him. She also said that awarding a medal in this way will not only be a title, but also many privileges, such as establishing a space city, developing asteroids, and even cultivating private guards, and also gaining a lot of voice in imperial affairs.

Establishing military merits, becoming a powerful soldier, becoming a nobleman, and contacting more core empire secrets is the greatest motivation for Xia Xiyan to join the Hayue Provincial Army and fight desperately.

Unexpectedly, Lu Meng glanced at Zhang Yuan and said with a smile: "Why, you, the God of War, have you also thought about it?"

"Something is wrong." Zhang Yuan said frankly. He and Lu Meng have lived and died many times. Zhang Yuan could completely reveal his mind to her.

At this stage, he has the intention to do this, but he has not made the final decision because he has far less knowledge of the Crimson Empire.

Unexpectedly, when Lu Meng heard Zhang Yuan's words, he shook his head flatly: "Zhang Yuan, I advise you to give up this idea. The so-called military merits and honors were quite reliable in the early days of the empire, but now it is just a beautiful lie. Those soldiers who awarded honors are just senior thugs of the hereditary nobles. It is a dream to rely on such a small medal to build the foundation of the family."

"Oh?" Zhang Yuan raised his eyebrows, waiting for Lu Meng to explain more.

Lu Meng didn't say much. She shook her head and said, "Actually there is nothing to say, the class has solidified. There are dark nebula, starry beast, interstellar robbers and various fanatical organizations everywhere. The security area is very limited. Since the empire has developed, these areas have been controlled by various nobles, and there is no place for later generations to gain foothold."

"Oh, so that's it."

Zhang Yuan nodded. He ended the topic and began to open his space folding bracelet, walked around the underground space, and put out the energy core, advanced printers, and advanced materials contained in the bracelet one by one.

He waved to Lu Meng: "Come and see my good things."

Lu Meng walked over, circled around the equipment and materials, and looked over the things one by one. After reading it, she pointed to the printed materials and asked, "Zhang Yuan, how many more do you have in this kind of material?"

Zhang Yuan took a look and found that Lu Meng was referring to the core magnetic permeability material of the doomsday-class mecha rhodium magnetic engine, Jade Leng Yu. This thing was taken out by Zhang Yuan from several doomsday-class powerful mechas in the Ash Valley Planet Belt. Originally, he had a total of more than 60 kilograms on hand, but after he built many rhodium-class magnetic engines, only 10 kilograms of these materials were left.

This is because the lava engine adopts a new architecture, which can greatly save materials to leave. These 10 kilograms of jadeite can create at most two rhodium magnetic engines in the upper stage of the Doomsday.

When Lu Meng asked, he touched his nose awkwardly: "That's all. Feilengyu is a strategic material that is strictly prohibited from flowing out of various empires. To synthesize this material, it is said that a thing called the Creation Furnace is needed..."

Zhang Yuan had long anticipated the material crisis. Another purpose of his visit to the Crimson Empire this time was to find high-end materials, because in a place where stars shine, the Crimson Empire's industry is the most developed and the largest exporter of high-end materials and industrial finished products.

The Om Empire and the City of Sky have a considerable dependence on the Crimson Empire in this regard.

Lu Meng squatted down and carefully picked up the jadeite. The surface of this dark green crystal with a crystal-like appearance was wrapped with a solid cold light, which was very delicate. It made people feel deeply attached to it at first glance, as if their minds were attracted to it.

After looking at it for a while, Lu Meng carefully put the Fei Leng Yu back to the suspended base and whispered: "Fe Leng Yu, produced by the Royal Higher Crystal Factory, worth 7 million star shield per gram, produced by the Imperial Royal Family's Creation Furnace powered by giant black holes as its energy core. It is the lowest-end product of the crystal factory."

Zhang Yuan had never heard of these news. When he heard it, he suddenly felt shocked: "Filing Leng Yu is the lowest, so what about going up?"

"Advanced, they are the Ice Emperor Jade applied to the Doomsday Top Mecha, the Sky Blue Stone applied to the lower mecha of the God of War, the Creation Crystal of the Middle Mecha of the God of War, and the Upward... I don't know."

Zhang Yuan was excited when he heard this, and he asked again: "The jadeite from the Aum Empire was imported from the Crimson Empire. Wouldn't they make it themselves?"

Lu Meng explained to Zhang Yuan carefully: "Of course they can make it themselves, but their technology is not as good as the Crimson Empire. The performance of their Creation Furnace is not as good as that of the Crimson Empire. Making the same weight of the Crimson Jade is much more expensive and the quality is slightly worse, which is not as cost-effective as imports. As for the higher-end Ice Emperor Jade, Sky Blue Stone, Creation Crystal, the Crimson Empire will not be exported, and the Aum Empire can naturally make it, but the cost will be relatively high. Correspondingly, the City of Sky is similar. About 150 years ago, the Dark Shura Empire successfully built its Creation Furnace, which is also the fourth Creation Furnace known to the place where the starlight shines. This made the Dark Shura Empire become the fourth interstellar power beyond the three empires."

Zhang Yuan asked again: "Lu Meng, do you know the rhodium magnetic permeability of the Creation Crystal?"

Lu Meng frowned and recalled: "It's about 7 yuan cut (unit). I don't know how much it is. I didn't have the authority to contact such top secrets before, but it certainly won't exceed 8. Because once it exceeds 8, it can theoretically create a pure-power mecha with infinite power. The Crimson Empire does not currently have this thing, and there is no place where the starlight shines."

This answer made Zhang Yuan tremble in his heart. Why? Because the activated steel of the spiritual mirror engine he used on the angel mecha is a spiritual superconductor, which is converted to magnetic permeability, which is only the 10 yuan cut in the theory!

7 yuan cut can create a god-level mech in the middle of the God of War, 8 yuan cut can theoretically realize a pure energy mech, and 10 yuan cut... Zhang Yuan finally knows how wasteful it is to use activated steel to build a doomsday upper rhodium magnetic engine!

He remembered the situation of the Earth Federation again.

"The Earth Federation has destroyed many demon doomsday mechas over the years. Fei Lengcui must have a lot of stock. General Denver drove the doomsday mechas. His rhodium magnetic engine should have Ice Emperor Jade. In addition, the lava engine I designed does not use high magnetic permeability crystals. It has created 60 doomsday mechas, and there is no problem at all... But what about 60 units after?"

If the Earth Federation does not have a Creation Furnace, there will be no continuous magnetic permeable crystals. As long as the demons are undefeated, war will continue to happen. 60 doomsday-level mechas will always be consumed, and the scarcity of magnetic permeable crystals will sooner or later become a big problem.

Create a furnace of creation?

It is absolutely impossible to do it in a short time. This is the foundation of the founding of major interstellar empires, and it is impossible to obtain technical information at all. So how can we solve the shortage problem?
