Yun Ruofei nodded casually, and the angry Xuanyuan Yu snorted coldly, flicked his sleeves and left, but he didn't see the corners of Yun Ruofei's mouth slightly raised behind him.

"Dad, how long can you stay here this time?"

"When this matter is over, I'll go back, your mother is still waiting for me at home!"

Mu Ange pouted, "My mother definitely misses us more, why doesn't my mother come?"

Seeing his youngest son like this, Mu Hancheng's hands itched, and he couldn't wait to slap him, who knew that this kid seemed to have eyes behind him, and he ran fast.

"Your mother has a serious business, do you really think everyone is as idle as you?"

"I knew you must be idle!"

"Hey, you stinky boy, aren't you looking for a beating!"

Mu Ange smiled, and Mu Hancheng was not angry, "How are you doing here?"

"Dad, you don't know it's fun here, my brother has separated and synthesized spiritual liquid from other medicinal materials, and made a mecha driven by spiritual power, and also made a high-radiation crystal energy cannon, which is super powerful, and can bombard a Yuanying monk, as long as the mental power is enough, even the distraction period is not a problem!"

"Regular, Dad knows that you like to study weapons, just like your mother, but you must know that the more things you study, the more powerful it is, the more dangerous you are, you must protect yourself, and the self-defense weapons that your mother made for you are always with you!"

Mu Zhengze nodded, "Dad, don't worry, in addition to the self-defense weapons that my mother made for us, I have also made a lot of them myself, so there will be no problem!"

"When are you going to go back to Blue Star?"

"Two years at the earliest, three years at the slowest, I still have a few experiments here, I'll go back when the experiments are completed!"

"Me too!" Mu Ange raised his hand, "Dad, I also have a few experiments, don't believe me, I'll take you to see it later!"

"Dad, I have established several factories in the Yuanyang Continent, specializing in the production of cars and helicopters, and I have made money, I now have hundreds of millions of low-grade spirit stones, as well as tens of millions of medium-grade spirit stones, aren't you and my mother also cultivators, these are all for you to use!"

Mu Hancheng looked at his youngest son dumbfounded, "Car, helicopter?"

Mu Ange nodded, "I changed the energy drive, the spirit stone drive, which is different from the energy drive over there, low-carbon and environmentally friendly!"

Mu Hancheng nodded, he didn't expect that he hadn't seen him in the past few years, and his youngest son would give himself such a big 'surprise'.

"Don't play too big!"

"I know!"

Mu Ange said that he was measured, the corners of Mu Zhengze's mouth twitched next to him, and he didn't know whether to say it or not, but in the end, Mu Zhengze didn't say it in the end, but he knew that his father would know sooner or later, but it was only a matter of time.

Mu Zhengze and Mu Ange's father came to Yuanyang Continent, as good friends of the two, Mo Yun and the others naturally wanted to visit, but after seeing Mu Hancheng, everyone muttered a little in their hearts, because this Uncle Mu's cultivation was actually lower than that of his two sons.

However, they just buried this matter in their hearts, no matter how low Uncle Mu's strength is, the strength of Mu Zhengze and Mu Ange in the future is enough for their families to walk sideways in the Yuanyang Continent, Mu Hancheng doesn't know what these teenagers think. Because he is not low in strength, but hides his cultivation.

"Dad, you see this is the spiritual liquid that I refined from various medicinal materials during this time, because many medicinal materials are limited, so I studied it later, and directly refined the spiritual liquid from the air, and a thousand liters of air can refine a hundred drops of spiritual liquid!"

Mu Hancheng looked at the transparent glass bottle in Mu Zhengze's hand, which was a liquid like water droplets, crystal clear, and looked particularly beautiful.

"At the beginning, I extracted the spiritual liquid from the spirit stone, and then extracted the artificial spiritual liquid from the medicinal materials, and then I thought that there is also spiritual energy in the air, why not extract the spiritual energy from the air, so that there is no need for spiritual stones, I have done an experimental comparison, a thousand liters of air in the Yuanyang Continent can refine a hundred drops of spiritual liquid, and a thousand liters of air in our Blue Star can condense twenty drops of spiritual liquid, although our Blue Star lacks spiritual energy, but the air is inexhaustible, although it takes some energy, but compared with the spiritual liquid, it is definitely beneficial and harmless！”

Mu Hancheng patted Mu Zhengze's shoulder, his son is only twelve years old this year, although he is only a minor teenager in terms of age, but he knows that his son is not a child, and he knows even more than him.

"Dad, this is the spiritual liquid I prepared for you and your mother, and you and your mother are also cultivators, which is good for your cultivation!"

Mu Zhengze took out a few tubes of spiritual liquid from the storage ring again, "This is the spiritual liquid that I specially prepared according to the bodies of my grandparents and grandparents, which can prolong life, you can bring it back when you go back!"

"They must be happy to see these gifts!"

"Dad, there are 10 million medium-grade spirit stones here, which I honor you and my mother, and there are all kinds of jewelry in it, all of which contain aura, and long-term wear is good for the body, you can also help me bring it back!"

The corners of Mu Hancheng's mouth rose slightly, and he nodded, "I heard Professor Fang say that you went to that Vientiane Secret Realm two years ago, and did you encounter any danger in it?"

Mu Ange's eyes lit up, and then he remembered that there seemed to be something, and said excitedly, "Dad, you definitely can't guess what we have gained in the Vientiane Secret Realm!"

Mu Ange didn't intend for his father to guess, in his opinion, his father would definitely not be able to guess, so he said, "Dad, my brother and I have made a contract with a demon pet in the Vientiane Secret Realm!"

"Dean Yun and Elder Xuanyuan both said that these two demon pets have the blood of the Divine Beast White Tiger in their bodies, although they are very small, but they are very precious!"

As soon as Mu Ange waved his hand, a majestic white tiger appeared in front of Mu Hancheng's eyes, and Mu Ange said to Mu Zhengze, "Brother, you release the big tiger too!"

Mu Zhengze nodded helplessly, expressing his helplessness about his younger brother's behavior showing off to his father.

"Dad, this is our demon pet, the big tiger, the second tiger, and the twins, are they a good match for me and my brother!"

Mu Hancheng nodded, "Zheng, An Ge, although you have now stepped into the ranks of cultivation, but don't forget that you are Blue Star people, no matter how strong you are, you can't do anything to ordinary people, let alone be a traitor!"

"Dad, my brother and I were taught by you and my mother, and besides, my brother and I have no intention of staying in the Yuanyang Continent to practice, our main goal is still in Blue Star!"

"No matter how you choose, neither your mother nor I will interfere, as long as you have a clear conscience!"

Mu Zhengze and Mu Ange nodded.

"Dad, do you want to go outside?"

Mu Hancheng shook his head, "Your mother and I came to Yuanyang Continent more than ten years ago, and we stayed for more than half a year, so we won't go out!"

"Dad, you visited my brother's laboratory, do you want to go to my factory to have a look, it is all new energy drive, safe and pollution-free, I think if it is after Blue Star announces the cultivation in the future, we can also replace the energy drive!"

"Let's talk about this later!"
