For Zhang Yuan, the strange spirit stone has always been a mystery.

If it is a naturally generated spirit primordial stone, it should be pure spirit, but it is not in the Grain Boundary Stone, they have a strong exclusive attribute, and they are only effective against the Golden Heaven Domain people, while he, an outsider, is highly poisonous.

Originally, he wanted to get the results of his mastermind research, but now, he himself unexpectedly got the clue of this strange spirit.

Zhang Yuan's heartbeat accelerated slightly: "If these strange spirits are really left by those so-called ancient gods, then this ancient civilization must control extremely developed spiritual technology, and if I can find the ruins, it will definitely be of great benefit to my research in the spiritual field!" ”

Now, he had a clue to the ancient ruins at hand, and that was the Grain Boundary Stone Mine that was currently occupied by the exiles!

The Boundary Stones in that cave contained a large number of Strange Spirit Primordial Stones, and this could not have come out of nowhere.

Zhang Yuanzhen wanted to go to the mine immediately to find out, but reason quickly stopped him.

"No, no, Mi Xiu definitely attaches great importance to that mine, and the defense system he has arranged in the mine is absolutely hell-level, and if it is not good, there is a hunter system. Judging from my current power as a white angel, once exposed, I am afraid that there will be no place to die...... Wait, I'll wait, wait for Ling Xiao to get the high-end equipment and materials, and then I'll improve my mecha. ”

As soon as he thinks his mech has enough power, he immediately doesn't hesitate to head to the Grain Boundary Stone Cave.

And once he did that, then it would be impossible for him to go back to the past, and even if he returned to the Golden Heaven Domain in the future, he would have to go incognito.

Because he is now the core figure of the military in science and technology, the military absolutely monitors him 24 hours a day, and he will no longer disappear out of thin air as before.

So, before leaving, he had to finish his final work.

In the following time, Zhang Yuan began to work frantically, and he continued to draw mecha design drawings, from the ordinary level to the doomsday level, without missing a single one.

And that's not all!

Zhang Yuan wrote another treatise, in which he explained in detail the role and use of strange spirits, and at the same time, he built a spirit infuser.

This paper, coupled with this spiritual infuser, can guarantee the energy of the Color Heaven Domain to continuously cultivate spiritually powerful warriors.

When he completed these design drawings, Ling Xiao also completed the task and delivered all kinds of high-end equipment and materials he needed one by one.

It can be said that the sharpest and most advanced equipment in the Golden Sky Domain, as well as the most precious materials, are basically here in Zhang Yuan. Using these things, Zhang Yuan can completely improve the performance of the White Angel mecha by a large margin.

"Assistant Ling, I recently had a wonderful idea, and I am going to use these things for experiments. This is estimated to take a long time. During this time, I didn't want to be disturbed. ”

"Huh? How long will that take? Ling Xiao asked hurriedly.

"I don't know, maybe a week, maybe a month."

"In this case, if someone with high authority wants to see you, such as General Li or something, how can I refuse?"

"You just said that I was studying the control of energy by mysterious forces, and you told him that I had reached a critical moment."

When Ling Xiao heard this, she immediately understood the importance of this matter, and she nodded again and again: "Oh, okay, I understand." I'm not going to let anyone bother you. ”

After the order, Zhang Yuan entered the studio.

The first step is to modify the White Angel Mecha.

He knew the White Angel mecha extremely well, and he could modify it with his eyes closed, so the speed of the modification was very fast, and the whole process took him 7 days and consumed 40% of the precious materials.

After 7 days, the White Angel mecha was reborn, its defense ability was more than doubled, and it had a very strong self-healing ability. It uses a new energy core, which Zhang Yuan named Supernova, with an energy output rate of 5 times that of the previous one and an energy reserve of 10 times that of the previous one. This guarantees the White Angel's near-perfect endurance combat capability.

In terms of combat, the power performance of the White Angel mecha has increased by 40% again, and the performance of the rhodium magnetic engine has not been improved much, which is too technically difficult, but Zhang Yuan still made a lot of improvements to it, and finally increased its performance by about 5%, slightly narrowing the gap with Mixiu's Dark Knight.

The perfect endurance, coupled with the almost perverted maneuver, has achieved the White Angel's incredible escape ability, so that even if he encounters Mixiu's Dark Knight in space, Zhang Yuan can easily escape even if he can't beat it.

The White Angel Mecha has been modified, this is Zhang Yuan's own business, but he uses all kinds of equipment and materials to provide Golden Heaven, and he naturally wants to leave something for Golden Heaven.

After thinking about it, Zhang Yuan decided to use the remaining materials to build a rhodium magnetic engine, which was his last gift to Golden Heaven.

The rhodium magnetic engine is almost beyond the limits of mortal intelligence, it is a miracle, and its internal structure is far more complex than ordinary people can imagine. Even if Zhang Yuan wants to build a rhodium magnetic engine from scratch, it will take a lot of effort.

On the eve of the start of work, he deliberately rested for the night and regained his energy before he really started.

Zhang Yuan did not stop for a moment, except for the most basic physiological needs such as eating, drinking, and Lazar, which took up some time, almost all of the rest of the time was devoted to the rhodium magnetic engine.

As time passed, Ling Xiao outside the studio became more and more worried, if it weren't for the fact that there would be some movements in the studio from time to time, she would really think that Zhang Yuan would have died inside.

Every five days, General Li Delin would contact her, and her answer was exactly the same every time, only saying that Zhang Yuan had made some breakthroughs in the field of mysterious power and was practicing in retreat.

She didn't say anything, she was afraid that General Li Delin's expectations would be too high, and if Zhang Yuan didn't succeed in the end, everyone would be embarrassed.

"Dididi~" General Li Delin's communication rang again, Ling Xiao looked at the time, and was surprised to realize that Zhang Yuan had entered the studio for 20 days.

"How is Zhang Yuan's situation now?" General Lee asked, a hint of worry in his voice.

"I'm still in the studio, I haven't come out." Ling Xiao whispered, she was afraid that the loud voice would disturb Zhang Yuan.

General Li continued: "The research of mysterious power is very difficult, let alone the practical use, the entire Golden Heaven Domain, thousands of laboratories, are all stagnant, which shows that this thing is not something that can be made at once, it takes a lot of time to accumulate. You go and tell Zhang Yuan now, your body is important, don't die! ”

Ling Xiao turned her head to look at the studio and said in a low voice: "But general, Zhang Yuan is different from others, he is a genius!" ”

General Li was a little annoyed, and he said in a deep voice: "Yes, he is a genius!" But genius is not God. You know Memphis, right? ”

Ling Xiao was taken aback: "Of course I know." What's wrong with him? ”

Memphis also said that he was going to visit, but somehow it was silent.

Li Delin sighed: "He has also been obsessed with this new field recently, all his thoughts are on it, the state is the same as Zhang Yuan, almost to the state of madness without eating, drinking or sleeping, yesterday morning, he had an accident, vomiting blood and fainting, after waking up, the whole person is crazy, I am afraid that it will be ruined." ”

"......" Ling Xiao was speechless in shock, and it took a long time before she spoke: "General, wait a few more days, right?" Zhang Yuan's physical fitness is very good, and he is still not very different from Memphis, Zhang Yuan eats regularly, and he will rest for a while every day, I don't think his face is too bad......"

Li Delin pondered for a few minutes, and finally compromised: "Hey~ Then wait another week, after a week he is still like this, he must be forced to recuperate!" ”

After hanging up the communication, Ling Xiao looked at the studio where the light was constantly shining and disappearing, and her heart was full of deep worry for a while.

Time continued to flow, one day, two days, three days, and on the fourth day, the door of the studio opened, and Zhang Yuan, who was full of stubble and tired, walked out of the studio.

Ling Xiao bounced up from the chair and rushed up: "BOSS, how are you?" ”

Piao Xue and Lewis also kept an eye on Zhang Yuan's mentor's situation, and also rushed over at this time.

"Mentor, has there been a breakthrough?"

"Mentor, are you all right?"

Zhang Yuan waved his hand, and a heartfelt smile appeared on his face: "I'm very good." ”

He turned his head to look at Ling Xiao, a pair of dark and deep eyes flashed with starlight: "Assistant Ling, you go and contact General Li Delin and tell him that I have a great breakthrough that is enough to change the world!" ”

Zhang Yuan did not hesitate to use the adjective 'great', because the rhodium magnetic engine he built this time is a new architecture, in terms of architecture alone, it is better than the rhodium magnetic core inside the white angel machine, the only deficiency is the material, but even so, the energy conversion efficiency of this rhodium magnetic engine has reached 30.9%, which has completely reached the level of the mainstream rhodium magnetic engine in the Starlight Land.

This new rhodium engine has the perfect potential for improvement, which is why Zhang Yuan named it 'Genesis 1' to distinguish it from the A-type rhodium engine he was using before.

In Ling Xiao's impression, Zhang Yuan has always been a calm and introverted person, the kind of calm person who won't blink an eye when the building around him collapses, and now, he is so excited, then he has definitely done a great thing.

"I'll contact General Lee now!"

A few seconds later, Ling Xiao was able to communicate with General Li.

"What's going on? Something happened to Zhang Yuan? Li Delin's voice was a little panicked.

"No, it's not, and I don't know what to say. BOSS, explain it to General Li yourself. Ling Xiao gave the communicator to Zhang Yuan.

Zhang Yuan took the communicator and greeted: "General Li, how are you doing lately." ”

As soon as Li Delin heard Zhang Yuan's voice, he was full of anger, and his heart settled down, and he smiled: "Haha, Zhang Yuan, you are terrible now, the originator of the mecha is you." ”

During this time, thanks to the maneuvering skills provided by Zhang Yuan, the combat effectiveness of the military mecha warriors has increased by leaps and bounds, and he is in a very good mood, and his attitude towards Zhang Yuan is naturally very good.

Zhang Yuan smiled slightly and said, "General Li, aren't you curious, why did I contact you today?" ”

"Oh, could it be that you've broken new ground? Or are you having trouble with your research? Don't worry, tell me if you have any difficulties, and I will do my best to help you. Li Delin immediately patted his chest and promised,

Zhang Yuan shook his head and didn't speak, he passed the hologram of the rhodium magnetic engine over: "There is no difficulty, it is to make a new thing." ”

Li Delin quickly received the image, he looked at it for a while, and couldn't understand: "What is this?" It's round, it's black, and there are so many dense holes on the surface, I look a little like a black ant nest. ”

Zhang Yuan laughed: "General Li, the full name of this black ant nest you see is 'Thinking Following Energy Control Amplifier', and after it is activated, it can burst out with a controllable energy output of up to 230,000 horsepower. With this thing, the mecha warrior can directly condense energy and cut the battleship into two sections with a single sword. ”

"Click~Click~Click......."

There was a chaotic sound on the other side of the communication, mixed with the shouts of many people, Zhang Yuan listened carefully, and could barely distinguish some of the sounds.

"It can't be!"

"So fast?"

"It's not as big as a soccer ball, and it can split a battleship?"

"What is controllable energy output?"

Not to mention the movement on General Li's side, the three people around Zhang Yuan were also stunned.

Piao Xue and Lewis only felt that this thing was awesome and more calm, while Ling Xiao was dumbfounded, and she could now fully understand why Zhang Yuan used the word 'great' to describe his achievements.

It's not just greatness, it's a miracle!

The chaos lasted for a full five minutes before it stopped, and then General Li Delin's hoarse voice sounded again: "Zhang Yuan, you swear now, every word you just said is true!" ”

"General Li, do I look like that kind of person? From the time we recognize it now, have I lied to you once? Zhang Yuan's voice was very calm.

Li Delin's panting voice came from the opposite side of the communication: "Zhang Yuan, you wait for me for two minutes, and I will immediately arrange the highest-level military meeting now." This is too important for me to do alone!"

"No problem."

Zhang Yuan hung up the communication and waited for General Li's notice.

Ling Xiao jumped over directly: "BOSS, how did you do it?" Do you know? Memphis has driven itself crazy in search of a breakthrough. You're good, you just made the finished product, how do you let other people live like this? ”

In front of her was the rhodium magnetic engine described by General Li as an 'ant's nest', Ling Xiao circled around this engine, wanting to reach out and touch it, but she was afraid of breaking it, not to mention how interesting the cautious appearance was.

Zhang Yuan nodded: "Sort of, for this thing, I worked hard, and I almost ran out of oil." ”

Ling Xiao immediately raised her head to look at Zhang Yuan carefully, and saw that he was indeed much thinner than some time ago, and blamed herself for a while: "BOSS, it's my fault that I didn't take care of you." ”

Zhang Yuan waved his hand, and was about to say a few words of comfort, when the communication rang, it was General Li Delin, after connecting, General Li's voice came: "Everything is ready, Zhang Yuan, come, show the miracle to the generals!" ”
