Cao Mengde's speed is unprecedented.

Here, Zhao Yu was learning about the changes in Shenzhou from Cai Bo over the years. In Luoyang, Cao Mengde learned that Zhao Yu had returned, without saying a word, threw down everything, jumped three feet high, dragged Guan Hai to the other courtyard.

"Sir! Sir!"

Before the speed vehicle landed, the door opened forcibly. Cao Mengde jumped down, shouted loudly, and kept his feet: "Sir, you are back!"

In the wooden courtyard hall, Zhao Yu laughed loudly. Before he got up, Cao Mengde rushed over, grabbed Zhao Yu's arm, and shook it hard.

Zhao Yu was so amused and laughed: "Stop! Stop! Stop!"

There was a mysterious sound in his tone, which instantly calmed Cao Mengde's excitement, and then smiled and said, "You are over fifty years old, are you? Why is the lord of a country like a young man?"

Although Cao Mengde was so excited and guilty, he still couldn't hide his joy and said, "It's not that I am like a young man, but I really miss Mr. Xu!"

"Go into the house first, sit down and talk."

So he went into the house and sat down. Uncle Cai hurriedly prepared tea. Zhao Yu said, "You are getting younger and younger after not seeing each other for ten years."

Cao Mengde smiled and said, "Although I have been busy with military and political affairs over the years, I have always put down my practice of the marrow washing sutra. With enough pills to assist me, I have achieved some success. I am naturally energetic and look young."

Zhao Yu nodded slightly.

Cao Mengde has clearly entered the realm of martial arts where the energy is contained and the spirit is seen.

After only ten years of busy military and political affairs, he can achieve such martial arts achievements. Even with a large number of elixirs assisted, it is not a small matter.

Martial arts practice, the pure process of strengthening external divine power is to nourish one's body, and the benefits of the pill are the most convenient. When you are strengthening internally, you must go deep into the word "intellectual". The understanding of the power of the power is the key. Many people are stuck at this level and cannot make progress, and Cao Mengde can still make breakthroughs in his busyness, which shows that he has a strong understanding.

No one can deny that Cao Mengde has extraordinary talent. His wisdom is indeed amazing.

Now he has entered the realm of accumulating energy and seeing the spirit. Even if he is stuck at the level of opening up acupoints, as long as he is not injured by external forces, he will have a lifetime of at least a hundred years. He is only over fifty years old now and will be over halfway through his appearance. His appearance looks younger than ten years ago.

"It's sir, my youth is as young as before, which makes me envious." Cao Mengde smiled.

Zhao Yu shook his head and laughed: "My surface has not changed, but my heart has changed. It's not as good as before."

Then I started chatting.

Zhao Yu talked about what he saw and heard over the years, which also made Cao Mengde very interested.

Zhao Yu said: "The earth is different from the east and west, the environment is different, and the species they are nurtured are also different. Whether it is animals or plants, there are big differences. Especially some strange things, there are heaven and earth. I discovered a place where the yin and yang cardinal converges in the southern continent of Dongshengzhou. Most of the year, thunder is like the sea. There are many mystery in it. If I hadn't been unwilling to neglect my wives and concubines, I would have to sit there and recuperate."

"Oh?" Cao Mengde was very strange: "There is still such a place?"

Zhao Yu said: "There is indeed. And there is more than one place. For example, the Antarctic Ice Field, under its ice layer for billions of years, there are many wonderful places. I also found a space under the ice layer, which is as warm as spring, and there are ancient creatures that have retained and reproduced."

"Oh!" Cao Mengde was particularly surprised.

"It's like the depth of the ocean." Zhao Yu felt a little regretful: "This planet has the majority of oceans, and I have never walked through it. Especially some extremely deep trenches, including ancient creatures. Even the deepest part, where the earth fire meets, I must be careful."

Zhao Yu has been around the world for the past ten years, except for not entering space, and has been there on the mainland and the ocean.

Especially in the ocean, the deepest pressure is huge. In the deepest places, sea water and earth fire converge, and water and fire occasionally explode. Even Zhao Yu has to act cautiously.

"I heard my husband's description of this world, since the large-scale construction of the talisman boat, I have been asking me to explore this planet every year." Cao Mengde said: "However, after all, they are all mortals, and they only explore a rough idea. Understand the terrain and many dangerous places, and I dare not go."

He also said: "The old Taoist priest Zuo Ci also rode a flying boat to the sky and almost died in the sky."

Speaking of this, he couldn't help laughing and was also a little glad: "I was quite moved at that time and wanted to go to Gaotian to see it. Fortunately, I was tied up by affairs and did not go with Zuo Ci's old Taoist, otherwise the consequences would be unimaginable."

Zhao Yu couldn't help laughing and said, "Why do you want to go to Gaotian? The air above the Gaotian is thin, and ordinary people have difficulty breathing. And it is extremely cold, and it will turn into ice after a few breaths. And once you break through the outer air circle and enter the starry sky, you will be lost accidentally and you will not be able to come back!"

Cao Mengde nodded repeatedly: "That's true. The old Taoist priest didn't believe in evil and wanted to go to Gaotian to find the Heavenly Palace. It was really awesome. Mr. and the real immortal faced him. He still fantasized about legends, which was really ridiculous. When he came back, he was cold and shivering. The old Taoist priest forced himself to stay in Gaotian for half an hour. If it weren't for the advanced martial arts, he would have been frozen to death."

Zhao Yu couldn't help laughing: "It's also a blessing for his profound martial arts. To go to the high sky, or even the starry sky, you have to make a lot of preparations. The air in the high sky is thin and extremely cold, so you have to make corresponding preparations. In the starry sky, the strong Yuanqi is surging, which will cause great harm to people. Even if the martial arts are advanced, you will not be able to bear it for long. Therefore, to explore the environment outside the planet, you must be cautious and cautious. At least you must make corresponding modifications to the talisman carriages and ships, such as keeping warm, isolating the strong Yuanqi, such as storing air or producing oxygen, etc.."

Cao Mengde deeply agreed and said, "The Taoist and Mohist Taoist masters began to study this area a few years ago, but the results were not great."

After a pause, Cao Mengde seemed to remember something, and was excited and said, "A few days ago, the old Taoist Zixu told me that they seemed to have some achievements. When I went to Mo Juzi, he said that there was some progress in the war weapon."

"Oh? Is it related to driving to the sky?"

Cao Mengde said: "That's true. The wonder of Taoist patterns is really amazing. Earlier, the Taoist patterns masters of the Mohist school used giant crossbows and chariots to attack them. Later, they had a sudden idea and thought that they could directly use the Yuanqi of heaven and earth to emit powerful power through Taoist patterns. So they kept studying."

"oh?"

When Zhao Yu heard this, he couldn't help but come to the nature and said, "This is a good direction for research."

Zhao Yu pondered for a moment and said, "The wonder of Tao patterns is that one is to gather the original qi of heaven and earth, and the other is to use the original qi of heaven and earth. If more ways to use the original qi of heaven and earth may not be impossible to achieve the goal of using the original qi of heaven and earth as a weapon of war."
