The next day, the ghost king, who was taught by Bai Yutang and ruined the three views, led his wife and daughter away......

Actually, I don't want to leave, in fact, I want to stay.

The Ghost King wanted to say this, but the development of the Bagua Gate, that is, the Tianji Gate, was too scary: in just over sixty years, it had hundreds of years of accumulation from other sects.

The most devastating thing for the ghost king is the Qilin list, there are ten people on the list, and eight of them are from Tianjimen, not counting Bai Yutang......

"It's such a bully!"

The Ghost King shook his head as he walked.

"Xianggong," the ghost king's wife, Xiao Idiot, covered her mouth, "It should be Mr. Liuyun's sake, right?" ”

The Ghost King nodded helplessly: "How did they cultivate it, and I haven't seen the disciples of the Tianji Sect go out to practice......

"Daddy," Baguio, who had not spoken all the way, finally spoke, "I heard Xiao Fan say that his senior brother Liuyun is best at arranging formations, and the most powerful of them is the Phantom Heart Array, which can make people understand a lifetime in a very short time. ”

"No wonder ......"

The ghost king felt a little tired: I don't know if the world is changing too fast, or if he can't keep up with the pace of the times......

"By the way, Daddy, I heard you just say that the one in front of Xiao Fan is the Beast God......"

Seeing his daughter looking at him, the ghost king sighed: "The origin of the beast god is troublesome......"

While staying in the Ghost King's family to discuss the Beast God, Liuyun and his friends were also talking about the Beast God......

"Master, since the beast god has been resurrected, let's rush over directly and kill him!" Zhang Zhengxin is domineering and leaking.

Liuyun nodded "with satisfaction": "In this case, the task of the beast slaughtering god is entrusted to you!" ”

Zhang Zhengxin was overjoyed: "Really? ”

"Senior sister," Renqing spoke, stretching out his hand and pointing to the sky, "You had a chance a few days ago, but now, if you make another move, you will be in trouble!" ”

After being reminded by his senior sister, Zhang Zhengxin remembered: The countryside is also connected......

"Master," Zhang Zhengxin pouted and complained to Liuyun, "why didn't you say it earlier!" ”

Blame me?

Liuyun was a little speechless: "The Qilin List was released before the Internet, right?" ”

Zhang Zhengxin pinched his fingers and calculated: excluded Zhou Zhou Xian, who had become an immortal, excluded his own junior sisters, and then excluded Duan Zhengning; The only ones who can fight are their own master and Bai Yutang......

"Master, you did it on purpose, in order to rob the monster, your old man ......"

"I didn't plan to deal with the Beast God," Liuyun shook his head with a smile, "Lao Bai, I don't have any kung fu ......"

Zhang Zhengxin muttered: "That ......"

"It's a water unicorn!"

Xiaobai got out of Liuyun's sleeve, jumped onto the table, stretched out his claws to summon an apple, opened his mouth wide, and took a bite......

Zhang Zhengxin was a little confused: "Why?" ”

Xiaobai put down the apple on his paws: "The water unicorn owes Qingyun the cause and effect, and this cause and effect is always owed and not repaid, which will affect growth." ”

"Master," Zhang Zhengxin stared at Liuyun with resentment on his face, "The four of us came here to be a coolie for you?" ”

"Don't say it so ugly," Liuyun gave the apprentice a roll of the eyes, "Tai Chi Bear, you also played, right?" ”

All right!

As soon as he mentioned his great cause of shoveling, Zhang Zhengxin's heart began to tremble: although he can't ride it, as long as he can watch it every day, he will be in a good mood......

"Also," Liuyun looked at Zhang Zhengxin, who was rolling in YY, "Sort out your own spiritual plantation, pick out what you don't want, I'm going to build a fixed secret realm." ”

As soon as they heard the secret realm, Renqing, Zhang Zhengxin, Wang Yuyan and Duan Zhengning pricked up their ears: although the immortals could use space spells, they all knew little about space; The semi-open fixed secret realm is undoubtedly an excellent way for everyone to understand the secrets of space.

Although everyone has also observed the construction of the twin towers, it is a closed space structure after all, and the space is directly fixed inside the twin towers, so it is difficult for everyone to see through the mysteries......

I heard that Liuyun was going to build a secret realm, and the happiest thing was Bai Yutang: after a group of immortals ascended to heaven, the benefits naturally stayed in Tianjimen.

Originally, Bai Yutang thought that the position of the master of Tianji Gate would fall to Zhou Xiaohuan's head, but after the Zhou Immortal Tribulation, Bai Yutang reacted: The mountain of Tianji Gate finally fell on his head......

Although the surface soft power of Tianjimen, such as talents and exercises, is no less than that of the three major schools of the righteous path, it is still a little worse in terms of hard power: the three major schools of the righteous path have been operating for thousands of years, not to mention the territory, and they also occupy the nodes of several major spiritual veins in the world; And Tianjimen, up to now, should only be decentralized, this is the gap.

With the secret realm, the Tianji Gate can be regarded as having the foundation to compete with the three major sects of the righteous path.

Of course, the difficulty of building a fixed secret realm is much more troublesome than that of space magic weapons such as Qiankun Bag, Qiankun Ring, Spirit Beast Bag or Spirit Plant Bag.

The process of making a magic weapon for space is similar to building a house, and it also requires the use of reinforced concrete or bricks to build the frame; And the fixed secret realm, there is no need to build a frame at all, because you live in the energy cover.

Naturally, the difficulty of making an energy shield is much more difficult than building a house.

However, for Liuyun, who was born with spatial supernatural powers, there is no essential difference between building a fixed secret realm and making a Qiankun bag, but the process is a little more cumbersome.

Of course, in order to popularize the secrets of space, Liuyun first did an experiment for a group of young newcomers: blowing soap bubbles......

Although he felt that his master was a little naïve, Zhang Zhengxin still patiently settled on Liuyun and blew the soap bubbles.

"Master, this ......"

"Don't worry," Liuyun took the iron pipe, dipped it in soapy water, and then inserted it into the soap bubbles that had been blown, and blew one, before raising his head and staring at Zhang Zhengxin with a grin, "Although the space is far more complex than this set of soap bubbles together, the basic principles are the same." ”

As he spoke, Liuyun inserted the iron pipe into the soap bubble in the inner layer, and released the gas inside, and the soap bubble on the outside returned to its original size......

"I see!" Zhang Zheng raised his hand proudly, "What Master means is that the larger the space magic weapon, the greater the impact on the outside space!" ”

Liuyun's face darkened directly: I said it, space is far more complex than soap bubbles, how simple are you......

"Master," Wang Yuyan frowned and looked at the soap bubbles on the table, "What you mean should be that the spatial magic weapon has little impact on the outside. ”

Liuyun's face looked a little better......

"One more thing you should pay attention to......"

Liuyun redid the experiment, but the soap bubbles were all blown up by spells, and the inner soap bubbles were blown up by the outer layer of air.

After that, the flowing clouds released the air opening of the inner layer of soap bubbles......

Seeing that the apprentices all looked thoughtful, Liuyun nodded slightly......

Space is far more complex than soap bubbles, not to mention that Zhang Zhengxin and others still don't know anything about three-dimensional geometry, so it is even more difficult to learn. Moreover, the description of multidimensional space involves the imaginary number system, and multidimensional space is also the most cutting-edge discipline in the interstellar era in which Liuyun originally lived.

The next day, Liuyun, who was in a popular science class, took out a specially made teaching tool, a strange-shaped bottle.

After seeing the bottle, Li Yuwei was happy: the origin of spatial mathematics, Klein bottle......
