Without the need for a systematic body shape, Wu Yan could feel that when he brought North Star and others back to this world, the degree of spiritual energy recovery increased again.

This is due to the upgrade of his Emperor Sword Yuanshen.

He was able to use this to determine the Magic Academy of the British Empire, and his research on magic must be more powerful than before.

But he didn't care.

As long as he continues to develop technology, there will be no god in this world. Without God, he will be an invincible existence.

In the underground space of the Ming Dynasty Palace.

Wu Yan began to use the key points of sword control to sacrifice and refine his heroic sword.

After obtaining the secret of sword control, he summoned the hero sword and kept leaving the hero sword outside since then.

Although it is a bit strange that Wu Yan is the Emperor of the Ming Empire, he is the Emperor of Wu after all, and the supreme commander of the Ming Empire's military. He has had many unparalleled deeds in the personal expedition, so it is normal.

Not only that, Wu Yan also arranged for people to create legendary stories belonging to the heroic sword, and promoted them with settings such as the national hero sword, the national protection sword, and the human emperor sword, which is also to help the heroic sword upgrade.

With the gifts from Xuanyuan Sword before, the heroic sword that can absorb relevant forces and improve itself has made significant progress in this regard.

But after all, the time is still short, and the legend of the hero sword has not really spread, so the effect has not been truly revealed.

What really improves the hero sword is Wu Yan’s sacrifices and refining over the past few days.

The Nine Yang divine power in the Dantian and the power of the Emperor's sword in the sea of ​​consciousness surged out of Wu Yan's body like a trickle of water, and then entered the heroic sword floating in front of Wu Yan.

The heroic sword, which should have been integrated, now seems to have meridians in it, allowing the power of the Nine Yang Divine Power and the power of the Emperor's Sword to operate along the mysterious trajectory.

The material characteristics of the sword body began to improve in such tempering, just like an ordinary weapon put into the fire and tempered for thousands of times. And more, the heroic swords were like sponges, absorbing the power that Wu Yan had put into it.

But if it were just like this, this sword-controlling technique would not have become the fundamental method of the Emei Sword Sect.

As Wu Yan continued to invest his strength into the sword body of the Hero Sword, the Hero Sword also gave Wu Yan feedback.

A little spark-like energy floated up from the sword body of the hero sword, and then flowed into the golden trickle of the hero sword from Wu Yan's body, and returned to Wu Yan's body.

This is a kind of retrograde and a kind of reverse tempering.

When Wu Yan was sacrificing the Hero Sword, the Hero Sword was also sacrificing his Nine Yang Divine Power and the Power of the Emperor's Sword, and then gave back the most essence and purest spark to Wu Yan.

Wu Yan, who was sitting cross-legged on the ground, felt the spark entering his body, and a slight arc was drawn into the corner of his mouth.

The spark did not enter Wu Yan's dantian, and merged with his Nine Yang divine power, nor did it enter Wu Yan's sea of ​​consciousness, and merged with his imperial sword and soul.

But it seemed to melt on his body.

The skin, flesh, bones, and even the meridians in it can all be enjoyed by this spark.

Wu Yan had practiced "Yi Jin and Marrow Cleansing Chapter" before, and essentially improved his roots and bone talents. However, "Yi Jin and Marrow Cleansing Chapter" is a martial arts level skill after all, and at his current level, it can no longer bring essential help to him.

Now, using Emei sword control technique to sacrifice and refine heroic swords is equivalent to that he is sacrifice and refine himself.

The stronger the hero's sword, the higher the talent of his roots and bones will be. Whether it is practicing the Nine Yang Divine Power or practicing the Emperor's Sword and the Yuanshen, it will have twice the result with half the effort.

Of course, there is another relatively insignificant function, which is to improve Wu Yan's physical fitness.

One night passed.

Wu Yan finally stopped practicing sword control.

Judging from his current internal energy recovery speed, there is another "fire source" Fire Qilin next to him to help him recover. You can imagine how much Nine Yang divine power was spent on a night of sacrifice and refining.

The heroic sword floating in front of Wu Yan still floated in its original place after losing Wu Yan's power supply.

There was also a golden sulfur flame-like light above the sword body, which kept wandering and flowing like breathing.

"For a while, the quality of the heroic sword should be able to surpass the sword of the Emei Sect's Yunzhong Qizi, but it will take longer to reach the level of the Tianlei Double Sword."

The strongest ranking of the magic sword in the Shushan Movie World is the Nanming Lihuo Sword, which can be described as an immortal sword. After all, it is a weapon brought back by the Emei Sect Baimei True Man from the "Immortal World". It also combines the Nanming Lihuo left by Baimei True Man, which is also called the Emei Fire.

Then there is the Emei Sect’s Twin Sword of the Mountain-Standed Treasure Heavenly Thunder, and then there is the Sword of the Qizi of Yunzhong.

Although the combat effectiveness of Yunzhong Qizi in the movie "Shishou" is very strong, based on Dan Chenzi's notes on the practice of sword control, Yunzhong Qizi only has not practiced his home. His practice of just one or two hundred years is far inferior to Wu Yan now.

Even if they practice magic power.

After all, Wu Yan's Nine Yang divine power is not only extremely high in magnitude, but also has a quality that is about to reach the flame power of the nine major countries of Marvel, and the flame power is comparable to the thunder power of Thunder God.

"Thanks for your hard work."

Wu Yan patted the fire kirin, who had been sleeping next to him for a night, acted as a source of light and heat, and stood up and left the underground space.

He has something to do today, or to go and take a look.

It has been more than a month since Beichen was brought back by him. After introducing him to Annie, Annie did not wonder about Beichen's magical abilities, but began to calculate Beichen's abilities as soon as possible, which could help it can bring.

After the relevant plan was determined, Annie conducted targeted training for Beichen. After some experiments, she finally started the violent soldier model of artificial intelligence combined with superpowers.

The Ming Empire, Xinjing.

Ming Academy of Sciences.

Wu Yan's arrival did not cause much noise, because today's actions have a certain level of confidentiality.

Apart from his confidant, there are only the scientist assistants under Anne in the Ming Academy of Sciences, who are qualified to participate in today's actions.

By the time Wu Yan arrived, the relevant materials were ready.

"Let's get started."

Wu Yan nodded to Annie and Beichen at the same time.

This is a warehouse-style building with a large space. Within thousands of square meters of space, the middle area is empty and neatly stacked with neat materials.

Wu Yan, Annie, Beichen and others were all standing behind the second-story fence more than 20 meters high.

After hearing the instructions, Beichen took a deep breath and closed his eyes.

Over the past month of training, she has already remembered the drawings designed by Anne in her mind.

In the world she should have existed, Wu Yan used her superpowers to build a moon underground base and spacecraft experience when she was guiding her to join her body. She also returned to the training center for more than a month.

It was not that she remembered her memories in another world, but that she could feel that she seemed to be born to do these things, which was her instinct.

The metal ingots stacked on one side were also extracted from iron ore by Beichen before using her superpowers.

The metal extracted by electromagnetic force is not pure iron or pure steel, but alloys with higher strength and value.

Because Beichen can not only extract iron ore, but also extract metals from other metal ores, and then perfectly fuse according to the ratio given by Anne.

It is possible to obtain high-light alloys without the need for smelting. It is simply a cheat.

Although the distance was more than 100 meters, the metal ingots were still perfectly controlled by Beichen. The regular shape disappeared and the metal ingots began to deform, as if they had completely melted.

More metal ingots flew up and threw them into it under the control of Beichen's superpower. A large ball of metal solution appeared in the air in the middle of the warehouse.

There was no exclamation. Everyone present had seen Beichen's ability before, but almost everyone's eyes were filled with envy, appreciation, amazement and other emotions.

Wu Yan and Annie were the calmest in the audience.

Even though he was following Wu Yan and had superpowers, Xiaoye was amazed at the moment that Beichen's superpowers were powerful.

Of course, Riven, who is studying with Annie, actually has superpowers, but she cannot compare with Beichen's superpowers at all.

The metal solution kept swimming and floating, but it was completely confined to a region without any outflow.

The floating height begins to decrease.

The irregular shapes gradually began to become regular.

When the metal solution becomes solid and eventually lands in an open area in the middle of the warehouse, it becomes a fighter.

If someone from another world travels over, you will definitely mistake it for F16 at first sight, and the cockpit is completely exposed and there is no take-off and landing wheel below.

But in fact, it's just a similar appearance.

Slap sex.

Wu Yan applauded.

In an instant, there were thunderous applause from the audience. Although there were less than one hundred people in the audience, it seemed as if tens of thousands of people were applauding at the same time during a concert.

This is Wu Yan's emperor's charm. He even applauded. How can others not applaud to death?

"very good."

After applauding, Wu Yan patted Beichen's head and said, "Thank you for your hard work."

In terms of feeling, it seems that there is no difference between treating the Fire Kirin?

"It should be my lifelong glory for your Majesty." Beichen was also very excited because she succeeded in one go.

"Let's have a break." Wu Yan said again: "Don't worry, we have a lot of time."

The main body of the framework for building a fighter jet is actually not a big deal for Beichen's superpowers.

But even if it is just the main body of the framework, it is actually too precise and consumes a lot of mental power.

Beichen nodded and said, "Please rest assured that within three months, I will definitely be able to have enough carrier-based aircraft carriers."

The Ming Empire still has only one aircraft carrier. The Royal Shipyard of the Ming Dynasty managed by Li Hongzhang is currently building destroyers, frigates and battleships that the aircraft carrier formation needs to be equipped.

Generally speaking, an aircraft carrier can be equipped with 80 to 100 carrier-based aircraft, but not all fighter aircraft are fighter aircraft, and they also need helicopters, reconnaissance aircraft and other models.
