"Boom~"

A tremor like muffled thunder suddenly came in from outside the window. Immediately afterwards, a slight tremor appeared on the ground. Zhang Yuan stood on the ground and felt a little unstable.

"What's going on? An earthquake?"

This day, he didn't go anywhere, and kept staying in the mechanical assembly room provided by the Holy Warrior Al to enhance the power of the White Angel.

Now that this huge movement suddenly appeared, he was surprised and hurriedly put down his work, and walked towards the door with some stuttering steps.

Outside the assembly room door is a large open space in the forest. There are more than a dozen small buildings with exquisite styles distributed around the open space. In the open space, several silver-white mechas also stood there motionless.

These mechas are in operation, holding weapons in their hands. It can be seen that they were having a fight the moment before, and their attention was all attracted by this unexpected movement.

Al introduced these silver-white mechas to Zhang Yuan, called "Judgment Warrior", which are the mecha models of the violent ranks in the Apostles of Light.

Zhang Yuan's qualification in the Apostles of Light is the White Angel. Although he is the most basic level in the Doomsday rank, his identity is one level higher than these violent judges.

He walked over and asked, "What happened?"

When these silver-white mechas saw him coming, they hurriedly stood up and bent down slightly to salute Zhang Yuan. One of the soldiers said, "The great lord of Kansas used grouting method to deal with the rebels in Blackhawk City. He injected high-energy ions with high temperatures up to 10,000 degrees into the mine, and the noise was very loud."

Zhang Yuan was very surprised: "He actually used 10,000-degree high-temperature ions to grout? He would kill all the miners in the mine!"

"Who said no?" A trial warrior spread his hands: "But the Grand Lord of Kansas has given an ultimatum of 12 hours in advance. Now 12 hours have passed, and the rebels are still fighting to the death, so they have such cruel means."

Is the ultimatum that has only been 12 hours? This news made Zhang Yuan feel nervous. He could feel that Han Sande had lost his patience.

He didn't care about the fate of the miners, he was worried that Han Sande might execute Lu Meng in advance.

"No, I have to get a new mecha right away. The 25% efficiency rhodium magnetic engine is too low, and the angel is too weak, and it must be improved, but this takes time, and the time is not short. What I lack the most now is time. I have a piece of activated steel!"

The structure of the rhodium magnetic engine is too poor, so use material properties to make up. Even if it is a wooden stick, if it is made with an ultra-high energy laser, its lethality will be absolutely amazing.

Activated steel is a mental power superconductor. Using activated steel to key components in the rhodium magnetic engine will inevitably greatly improve energy control efficiency.

Thinking of this, Zhang Yuan returned to the assembly room without saying a word.

There is a thunderous-level Thunder printer there, the main brain also has super printer function, and with activated steel, he will definitely be able to produce a high-efficiency rhodium magnetic engine.

Zhang Yuan was anxious to build a rhodium magnetic engine. After he turned around and left, several trial soldiers from the clearing ground in the forest looked at his departure and whispered.

"Is this the jihadist chosen by Seraph? Are you too young?"

"I don't think this guy looks like a warrior at all. He's stuck in the assembly room all day, but he looks like a nerd."

"I also feel this way. I have seen many selected jihadists. To be honest, this is the most common one. I heard that he only got one angel mecha, hehe."

"Okay, okay, don't talk too much. Even if it's a White Angel, it's a Doomsday-level mecha, which is definitely stronger than you and me. Let's continue to train. If this continues, Dallas will definitely not be able to hide it. The battle is right in front of you." A warrior said.

"What I said," the other soldiers agreed, and several people continued to train.

Zhang Yuan naturally didn't know what these soldiers said. Even if he knew, he wouldn't have any turmoil in his heart. After returning to the assembly room, he said to his main mind: "Enable the A2-type rhodium magnetic engine structural template."

He called the most basic rhodium magnetic engine structure the A0 type. If the current materials are used, the energy conversion efficiency of the A0 type is less than 20%. After that, during the deduction process, Zhang Yuan will rename it every time he completes a small breakthrough.

The so-called a2 engine structural template is that after two small breakthroughs in succession, the energy conversion efficiency of this structure is about 20.7%, which is about 0.9% higher than the most basic version.

This energy efficiency is still quite low, but this is already the best rhodium magnetic engine structure at Zhang Yuan.

"The template has been enabled." A reply came from the main brain.

"Enable the super printer function and start printing the control parts of the engine area a, β, and γ areas."

"The command is received and printing!"

At the same moment, Zhang Yuan felt that his muddle spirit stored in the folding space began to burn at high speed, and one fine part after another was quickly formed.

The rhodium magnetic engine has a very fine structure and it takes a long time to print these parts. During this period, Zhang Yuan was renovating the White Angel Mecha.

The main reason why this mecha is so weak is not structural problems. It is simply because the materials used are too low-level and cannot have too strong loads.

Zhang Yuan did it very simply, which was to replace the parts of the White Angel with more advanced materials, and at the same time optimized the local position of the White Angel.

With a two-pronged modification, this angel mecha is undergoing a complete transformation.

He was very focused on the modification, and I don’t know how long it took. When the modification progress of the angel mecha reached about 90%, he heard the voice of the main brain: "The rhodium magnetic engine parts have been built, and a total of 23,311 points of comminuted spirits are burned, and the remaining comminuted spirits are 12,281 points."

"Very good!" Zhang Yuan was delighted and walked quickly to the fine parts assembly instrument in the assembly room. He held the robotic arm in one hand and took out the rhodium magnetic engine parts with the other hand, and began to quickly assemble them.

The size of the rhodium magnetic engine is generally not large. If the adult's head is as big as that of an adult, it can be called a large rhodium magnetic engine. The one Zhang Yuan wants to build is a medium-sized one. After assembly, it will be a 13m-sized ball.

In his calculations, it should be about the same power as the rhodium magnetic engine on the mid-doom mecha.

However, there are 27,382 parts of such a small size, which are as thin as hair. The largest one is only as big as an adult's thumb, making it very difficult to assemble.

Zhang Yuan did not dare to be careless at all. During the assembly process, he activated his mechanical heart, and his pure spirit began to burn at an ultra-low speed of 0.01 points per second.

About three hours later, Zhang Yuan assembled a thin hair energy conduit, and the spherical rhodium magnetic engine was roughly in place.

Everything is ready, only the core area parts are left.

‘Hu~’ He took a deep breath, calmed his mind, and then took out the activated steel.

This thing looks like an ordinary stone on the outside, and no one will pick it up when thrown on the ground. Only Zhang Yuan knew that this thing represented the most advanced technology of the powerful Eternal Empire tens of millions of years ago.

Take the small grinder, carefully grind the 'stone' into nano dust, then throw it into the Thunder printer and start printing the parts.

Time passed minute by minute, and one small and fine part after another was generated in the printer. After about half an hour, the activated steel was consumed, and Zhang Yuan saw a lot of strange things.

Assembling core parts is the last and most challenging step, success or failure is here!

Turn on the fine parts assembly instrument again and install the activated steel parts one by one into the a2 type rhodium magnetic engine. This process is very strict in assembly accuracy and does not allow any error.

Zhang Yuan focused on it, and he clearly felt the energy flowing away in his body.

It was obvious that this work did not take any effort, but Zhang Yuan felt sweat beads oozing out of his forehead and back, and his arms were sore and painful, and he couldn't control it.

"It's almost done! It's almost done! Hold on!" Zhang Yuan kept saying in his heart. Whenever he felt that his arms were really unable to control, he would stop and rest until he made sure that his arms had resumed precise control before starting again.

The light outside the window gradually darkened and gradually became brighter, and the sound also went from noisy to silence, and then from silence to noisy, the sound of birds singing, and the sound of the training of the judge soldiers, each sound came into Zhang Yuan's ears, but Zhang Yuan did not react at all.

Occasionally, there will be rumbling explosions in the sky. Whenever these sounds appear, Zhang Yuan will immediately stop the assembly work and will continue to assemble after the surroundings return to calm.

After the light outside the window became bright and dark twice, Zhang Yuan assembled the last part on the rhodium magnetic engine.

With an inaudible vibration, a slight white glow appeared on the surface of the a2 rhodium magnetic engine. The light flashed for about 0.1 second and disappeared. Then, the silver ball with a diameter of 13 cm appeared in front of Zhang Yuan.

The surface of the ball is very smooth, just like a mirror.

In the eyes of others, the ball did not show any mental fluctuations, and looked similar to a stainless steel ball. However, in Zhang Yuan's eyes, the ball showed a faint mental fluctuation. During this fluctuation, Zhang Yuan felt a strange sense of intimacy, as if the ball was a part of his body.

This is the spiritual binding function of the main brain. This rhodium magnetic engine uses a large number of super printer parts, which can only be used by Zhang Yuan. For others, this is no different from scrap iron.

Zhang Yuan reached out to grasp the ball and concentrated his mind to perceive the situation of the rhodium magnetic ball. After a moment, he felt a slight movement in his heart, and it was actually fused with the rhodium magnetic engine.

Immediately afterwards, something even more strange happened.

Zhang Yuan suddenly found that he was very sensitive to the changes in the energy in his surroundings. Where is the temperature high? Where is the temperature low? Where is the energy concentrated? He could perceive it one by one. He also felt in his heart that he could control these energy.

He tried to do this, and then something wonderful happened.

"Hu~" A white flame like glass appeared around the rhodium magnetic engine, and about one meter away from the flame, a white cold frost mist appeared in the air.

The reason for this is very simple, because Zhang Yuan absorbed the energy in the air around the rhodium magnetic engine. Because there is not much energy in the environment, he can only generate this ordinary flame. But if there is a doomsday energy core around him, then the rhodium magnetic engine can exert its power to destroy the world.

Zhang Yuan was very excited and full of pride: "Main brain, calculate the performance of the rhodium magnetic engine"

"It is being analyzed and analyzed and completed. The current energy conversion efficiency of the rhodium magnetic engine is 42.3%. The stable output power of the rhodium magnetic engine is 228,100 horsepower, the ultimate output power is 378,292 horsepower, and the limit time can last for 0.8 seconds (revitalized steel superconducting performance support!)."

As soon as this data came out, Zhang Yuan couldn't help but feel ecstasy.

The real data is a long way higher than the power he calculated, and the stable output power is the same as the mid-term of the Doomsday, while the extreme output power is close to 380,000 horsepower. This is the data of the mecha in the first stage of the Doomsday. Although it only has 0.8 seconds, it can only issue one move, and considering the mecha energy core and mecha performance, there are many restrictions, but this is enough to become his killer weapon!

He put away the rhodium magnetic engine and whispered: "With you, I finally have the power to fight back! I finally become a real strong man! You are all silver-white, as bright as a mirror, full of spirituality, so I will call you 'spiritual mirror'."
