Chapter 1711 (1/2)

”It's really not simple. The art of heaven and earth is the art of space. It not only needs to engrave space runes, but also needs the most appropriate materials to carry them. At the beginning, it was cast with Xumi stone and space stone of space attribute. However, this kind of space material itself is very precious and can't be used on a large scale. It was later that a fish was found that finally found a solution.”

Pei Ju also nodded.

”Fish?”

Yi Tianxing looked at them with interest.

”Yes, it's a very special fish. It's named kunxu fish. According to the exploration, it should have a trace of Kunpeng's blood in its body. The biggest feature of this kunxu fish is that it can eat and is very greedy. Moreover, it swims very fast. It's silvery white all over. It swims in the water like a silver lightning. It's amazing. After catching it inadvertently, I found that, These kunxu fish can swim very fast because of the scales on their bodies. ”

Pei Ju also said calmly.

This kunxu fish is definitely one of the most important discoveries of Dayi in recent years.

On the fish scale, it contains the spatial characteristics, but also has the magical power of hole emptiness, which can naturally gather the power of space and connect the inner and outer heaven and earth. Each fish scale can become a spatial channel to transmit the vitality of heaven and earth and various substances. Very mysterious.

This surprised the people of Tiangong Pavilion. They began to study how to engrave the Runes of heaven and earth cave on the fish scales and then integrate them into various buildings. This attempt surprised the people. Beyond previous imagination.

It not only perfectly carries the runes and constructs the heaven and earth cave, but also makes the cave have air, heaven and earth vitality, connected with the outside world, and even almost identical with the outside world in the heaven and earth cave, which can be called perfect.

It's also a kind of luck to find kunxu fish.

”What is the number of kunxu fish and whether they have been kept in captivity.”

Yi Tianxing's eyes twinkled and asked in a deep voice. It has been known that the key to the method of heaven and earth cave lies in the Kun virtual fish. If there are Kun virtual fish, there will be fish scales. If there are fish scales, we can build heaven and earth cave. Now the key is the number of kunxu fish and the scale of reproduction.

”The number of kunxu fish is not very large. They have been kept in captivity. When they were discovered, there was only one school of fish, about more than 100. Now they have multiplied for decades, only more than 3000. However, to take fish scales, you don't need to kill them. You only need to take down some of them. As long as you board for a period of time, you can re derive new fish scales.”

Pei Ju said slowly.

The number of kunxu fish is difficult to increase for a time, and the spawning cycle is too long. It only spawns once every ten years. Moreover, after spawning, the rate of hatching, breeding and survival is not high. It is lucky that ten thousand fish eggs can survive.

Otherwise, the number will naturally be more than what it is now.

Fortunately, the number of fish scales needed to build the heaven and earth cave is not large. They are all built by means of Sancai array, wumang star array and Bagua array. All they need are three, five and eight fish scales. Otherwise, the fish scales are really not enough.

”Once a decade, kunxu fish lay eggs now.”

Yi Tianxing asked.

”Kunxu fish have laid eggs these days. It is expected that tens of thousands of kunxu fish can be added this time.”

Gongshu Lin said confidently.

”Not enough, the survival rate is not enough. After the pilgrimage, Pei Aiqing can go to the star picking building, draw evolutionary medicine from the building, integrate it into the fish eggs, enhance the vitality of the fish eggs, go to the moon well water for breeding, and water the holy liquid in the colorful animal soul pool. Do everything possible to increase the survival rate and speed up the breeding speed.”

Yi Tian made a decision after a little meditation.

These fish eggs are precious and can't be wasted.

The survival rate must be increased as much as possible. I believe that with these preparations, the survival rate can definitely be raised to a very considerable height. This time, he did not want tens of thousands, but hundreds of thousands, or even millions. Only in this way can we meet the increasing demand of Dayi in the future.

”Yes, Emperor.”

Pei Ju and Gongshu Lin both showed a happy face and promised at the same time.

There is no doubt that kunxu fish scale plays an important role in the Ministry of industry and Tiangong Pavilion, which can be called strategic. Naturally, the more the better. In the future, we can play an important role. This is a strategic resource. The premise is that it must be large-scale.

”Weichen believes that Dayi Xiancheng can be expanded again. Outside Xiancheng, it can be expanded again. The new second ring road can also alleviate the pressure and accommodate more people.”

Huang Chengyan suddenly said.

Just like xuanhuang City, it can also expand the second ring road and the third ring road. This expansion will naturally increase the accommodation space.

”Well, it's feasible. All immortal cities are allowed to expand, and then the second ring road is expanded outside to control the population of immortal city to 4 million.” Yi Tianxing agreed after a little meditation.

After the expansion of Xiancheng, it can accommodate 4 million, but he does not want to reach this figure. Dayi wants to expand, but also hopes to have a steady stream of people who are willing to go to the new immortal city and sit on the town. This is in line with the interests of Dayi. However, we still need to consider various emotions that it is difficult to move people's hometown, relatives and friends and others in Dayi.

”The emperor, the minister has this.”

Just then, Jia Xu, the head of Tiance mansion, came forward and said.
