"What key technology?" Doyle was surprised.

"Energy compression purification technology, we need more powerful energy. Without energy, any warship is a decoration, and any high-tech weapon is a floating cloud. Regarding this technology, I have handed over to Ruskin, who studies energy. He has made great progress. It is said that he can almost create the lowest energy block." Yang Yu said very cautiously. In fact, this is what he is most worried about, because there is really not much energy on the earth. If you want to build more warships, you can only go to the universe to find energy. The moon is a good choice, but he doesn't want to dig the moon into a bumpy pit, otherwise the earthlings will be looking for the moon in the future.

His intention is obvious. The first batch of warships were regarded as transport ships. The main function was to go to planets outside the earth to find resources to replenish the earth, and then start to build higher-level warships in the second or third year. Therefore, what hinders the development of earth's technology is no longer technology, but countless resources.

"I understand." Doyle pondered, "The foundation of all technology cannot be separated from energy. Ruskin is very talented in energy, and he will not disappoint his teacher."

"I believe him, too." Yang Yu smiled.

Two days later, Yang Yu handled everything, and then he began to retreat.

"We must break through the realm of the soul." He told himself this. Only when he reaches this level can he have the opportunity to fight Cao Qianqiu and not be dumped further and further away.

Before Yang Yu went into seclusion, he found Mr. Qi and Liu Xueyao to manage external affairs together. After so many years of experience, Liu Xueyao has long been the president who managed a small company, but an executor with a perspective on the overall situation. She understood Yang Yu's purpose, and everything she did was basically Yang Yu's idea.

"Old Qi, Brother Yu has gone into seclusion, which may take a month. During this month, we have many things every day. If I don't understand anything, please don't be surprised." Liu Xueyao still respects Old Qi very much. This is the person Yang Yu found. Being polite to Old Qi also represents respect for several other forces. On the other hand, Old Qi is indeed very capable.

"You are welcome. You don't need my advice. I'm here to run errands for you. Some things that are inconvenient for you, so let me go. My old face is still useful." Old Qi smiled. In the Haotian Sect, he admired Liu Xueyao more and more. As Yang Yu's eldest wife, Liu Xueyao can handle internal affairs in an orderly manner and get along with other women like sisters. This is definitely not something that ordinary people can do.

Liu Xueyao smiled and said, "Old Qi, don't make fun of me. There are still many things that have not been dealt with today. You can come here to help me refer to it first and see if I'm dealing with it."

"Okay!" Mr. Qi naturally would not refuse.

In the hall, Liu Xueyao put a lot of documents around her. The ancient emperors probably looked like this. If you think about Yang Yu now, it seems that his identity is no different from that of the ancient emperors. Seeing Yang Yu busy every day, Liu Xueyao also hopes to help Yang Yu and share some pressure for Yang Yu, but some things must be taken by Yang Yu himself. This time, Yang Yu had to stand up, so she took the initiative.

"This matter was handled well, with rigorous thinking. There was no mistake in the middle. This was exactly what Master Yang said before. The interstellar soldiers he recruited in the future were also put into the desert to train. This would allow them to make progress faster." Old Qi praised.

"Old Qi, let's look at the following one. This is about the West..."

Above the sea, three thousand meters below the sea.

Yang Yu sat cross-legged on a stone, and the surrounding sea water seemed to have no effect on him. This was a situation that only after a deep understanding of the laws of water was found. In fact, Yang Yu began to retreat in the sea a year ago. This was not his obsession with cleanliness, but if he was not in the sea, the momentum he occasionally exuded could easily cause chaos in the spiritual energy of the Haotian Sect.

Three thousand meters deep, whether it is deep or shallow, a strange fish with two sharp teeth saw Yang Yu. He had not eaten for a long time. The resources in this sea area seemed particularly barren. When he saw Yang Yu, he naturally treated Yang Yu as food. He ran towards Yang Yu excitedly, but when he bit him, he heard a "cuckoo", and his two sharp teeth were broken.

The strange fish was frightened. He clearly felt the breath of life, but why did he bite it and it seemed to bite the hardest stone? He was so scared that he quickly retreated. At this moment, a momentum spread out around him. Many stones around him turned into powder, and his body was cut in half by this momentum.

The strange fish made a harsh cry. He was really scared. Fortunately, his vitality was very strong. He didn't care about the broken half of his body. Anyway, he could grow back in the future. He turned his head and ran. He ran as fast as he could, and disappeared in the blink of an eye.

At this moment, Yang Yu naturally didn't know what was going on. In his mind, countless soul powers began to condense, and gradually a phantom became more and more solid. This was the soul he had been looking forward to for a long time, the second life of the warrior. He had taken no less than three Star Soul Pills and dozens of Big Soul Pills, but he always felt that something was missing.

He has been in seclusion for more than twenty days.

The power of the soul became more and more concentrated, and the phantom became smaller and smaller. A soul villain gradually took shape. The arms, arms and head could be seen very clearly, but it was obvious that the soul villain's eyes were still tightly closed.

Yang Yu knew that it was time to be critical.

A pill suddenly appeared. This was a level 8 item he exchanged in the system. It was called the Soul Pill, which was an upgraded version of the Star Soul Pill. The exchange price in the system was 300,000 points. If there were not enough redemption points, he would not be able to put it down. This was the most suitable pill for him.

Making up his mind, he swallowed the soul pill in one mouthful.

The majestic soul power rushed straight into the sea of ​​souls, like a river breaking a dam. The villain in the soul suddenly moved. He opened his mouth and sucked it. Countless soul powers were swallowed by him. His body became more and more real and more vivid. His eyes, nose, and even eyebrows appeared. After everything was solidified, the villain of soul suddenly opened his eyes and saw a divine light rushing straight into the heavenly court. Yang Yu instantly felt that everything outside was different.

"It's done!" Yang Yu murmured to himself. He was extremely excited. He didn't expect to break through like this. However, looking back on the hardships along the way, it seemed natural. When his mind moved, the soul villain flew out directly.

This is, the soul!

The soul is the condensation of the soul, which can leave the body and travel through space. As soon as he reaches the outside world, he feels the strong power of heaven and earth. The endless laws seem to be right in front of him. In front of the soul, all the laws of heaven and earth seem to be without clothes.

"As expected, we warriors can understand any laws in the future." Yang Yu smiled, but when he was proud, he felt that the situation had changed, the spiritual energy of the world outside became extremely unstable, the sea suddenly rippled, and the huge pressure made the surroundings very gloomy, and he even felt something locked in him.

He quickly reached the sea and was stunned.

What he saw was dark clouds in the sky, thunder rolling, and the spiritual energy in the radius of nearly a hundred miles was mobilized, and the spiritual energy was turning into thunder and lightning. This was not the most terrifying thing, mainly because the core of the lightning was him.

Yang Yu didn't want to be struck by lightning. He quickly flew out more than ten miles away, but as soon as he stopped, the lightning gathered in the sky again and could not even be shaken off. This reminded him of two words: Passing the tribulation!

Not bad, this is a tribulation!

"Brother, why do you have a heavenly disaster?" Xiaoshui didn't know when it appeared.

"Yang Yu, don't hide anymore. The heavenly tribulation is a test for the heavenly creatures in the universe. Like the twelve starry sky beasts, they have to experience several heavenly tribulations in their lives, and they can be judged as heavenly creatures by heaven and earth. This is an affirmation of the human bloodline on earth and your cultivation. In the universe, not everyone in the Rakshasa tribe can experience the heavenly tribulation." Jiuzhao stood in the distance and shouted at Yang Yu, how could such a large-scale spiritual energy mobilization be hidden from him, but he was also thundered.

Yang Yu didn't know whether to be happy or cry, but now he didn't have time to think about this. He had to welcome the heavenly disaster with all his heart. When he calmed down, the world became extremely lively.

The satellite locked in Yang Yu, and the world was broadcasting the scene of Yang Yu's tribulation.

A naughty child pointed to the TV screen and said, "I have passed the tribulation and become an immortal. Lord Yang has passed the tribulation and become an immortal. We are really an immortal clan. I want to become an immortal, I want to practice, I want to join the Haotian Sect."

"Is this... the legend true?" an old man with white beard said to himself, "How could there be a real heavenly tribulation? Is this the rhythm of becoming an immortal?"

A student party seemed to go crazy: "It's really about experiencing a tribulation. Those online novel writers are all written by real, my mother! They are simply predicting the uncertainty!"

Don’t you know that a group of online writers have been sweating profusely. How could they know this? They just wrote it based on imagination. But now they are verified by Yang Yu personally, which makes them very excited.
Chapter completed!
