He saw that win and destroy stretched out his hand, and a golden light flashed, which had been shot at Zhou Bai.

Zhou Bai poured out a pale yuan Shen force and grabbed the golden light.

Then I saw that the golden light was reflected by a flying sword that was like a crystal, in which there were golden streamers.

It is the free Geng gold flying sword created after the upgrade of Chengying sword.

Yingzao said, "the sword embryo of Chengying was preserved, and then 21 precious materials such as Taibai sand and star stone were added. On the basis of the original Rune of Chengying, 180 runes of the third realm were added, which made this free Geng gold flying sword."

"But because of this, now this flying sword doesn't have more than 3000 yuan divine power, and it can't be fully driven."

"And since it's the relationship of flying sword, next don't forget to refine flying sword by Yuan Shen sacrifice. Have you learned from Yuan Shen sacrifice?"

"Well, the snake has taught me." Zhou Bai controlled yuan Shenli to rotate the flying sword, and he could see the faint Rune flashing under the crystal material.

Zhou Bai said in the sea of knowledge, "Tina, come and refine this flying sword."

Because the flying sword belongs to the long-distance attack, it often needs to attack beyond the scope of the yuan divine power. Therefore, in order to prevent the flying sword from being captured, there is the yuan divine sacrifice.

As the unique power of the yuan God, the yuan God's continuous output is needed to maintain. Only after reaching the fourth realm, the yuan Shen is strengthened again, can the yuan Shen force survive for a period of time after leaving the connection of the yuan Shen.

However, when the way of heaven was distorted in the past, you can get out of your body and attach yourself to the flying sword, so that you can come and go freely, and carry out flying sword assassination across a very long distance.

But now the way of heaven is distorted, and there is a risk of distortion when the yuan God comes out of the body, so the way of using the flying sword has also changed, becoming the method of the yuan God's sacrifice and refining.

The so-called method of refining the yuan God is to inject a part of the yuan God power into the flying sword. Through special materials and runes, the yuan God power injected into it can continue to exist for a long time after leaving the human body.

Although the structure of Rune and flying sword still needs more than 3000 yuan divine power to launch, it also enables monks to use flying sword from a long distance in the third realm. The only thing to do is to refine flying sword with Yuan divine sacrifice every day and inject yuan divine power into it.

Of course, the distance of this flying sword still can't be compared with the distance of the flying sword of the yuan God out of the body before the distortion of the heaven.

But in the third realm, the combat distance of flying sword can also be increased to more than 300 meters. With the improvement of cultivation, this distance can continue to rise.

Christina said, "is it OK for me to practice this flying sword? Didn't you use him to practice Xinghe Tianbao sword?"

Zhou Bai said, "no problem, there are my sword moves and extraterrestrial powers in the flying sword, plus the 500 meter distance of Tianhe starburst sword, even if I don't practice it with the yuan God, I can manipulate it. After you practice it, we can use this free Geng gold flying sword from a long distance together. Within 300 meters, the flying sword can exert our two powers at the same time."

So Christina began to refine the flying sword with the Yuanshen sacrifice.

At the same time, Zhou Bai looked at the results of his ten day retreat.

For ten days, I almost didn't even have time to sleep, and I survived with extraordinary food and physical resilience.

But it also brought fruitful results, which made Zhou Bai's laziness value exceed 1million points, and finally became the last star of the decline chart 'decline disaster'.

Zhou Bai observed his consciousness of the sea, and he saw that the yuan God, who had turned into a wheel and combined with the divine map, had changed greatly at the moment.

Zhou Bai could clearly see that a pale figure similar to him was sitting in the middle of the sea. There was a tiny wheel rotating on the belly of the figure, which was the star point of the nine pictures of natural disasters.

"Is this the God of natural disaster?" Zhou Bai secretly said, "even if the new field of natural disasters has not been opened, I don't know what kind of power that Guihai Heisha will have."

"But no matter what, I shouldn't use this for the four schools' big match this time. It's just a group of little kids. With my current strength and physical quality and Tianhe starburst sword, it's enough to defeat them."

A moment later, the flying sword sacrifice was finished, and Zhou Bai followed Ying Zao into the flying car and went to the position of Beihai city.

The speeding car went northward at supersonic speed all the way, crossing countless wilderness, mountains and rivers, and saw that the ground below gradually began to appear snow, and finally there was white snow all over the sky. What appeared in front of Zhou Bai was already a snowfield.

When the flying car slowly stopped, what appeared in front of Zhou Bai was an endless mountain range.

Zhou Bai looked at the snow capped mountains below curiously and asked, "why did you stop? Is it here? I didn't see the city."

Win Zao smiled and directed the car to fall: "Beihai city is different from Donghua city. It's an underground city."

Zhou Bai exclaimed, "underground city?"

He saw the flying car falling towards the mountains below. After turning left and right for a while, he came to a brightly lit outpost. He stepped down from the flying car and several soldiers greeted him.

Win and destroy said, "I'm win and destroy of Donghua road school. This is my student Zhou Bai, who came to participate in this four school competition."

Next, identity verification and physical and mental examination were carried out. After confirming that there was no problem, Ying Sui and Zhou Bai, led by several soldiers, entered an elevator.

The elevator they took was completely surrounded by visible transparent glass. At the beginning, they could only see black rock formations, but after falling for dozens of meters, their eyes were empty, and there were no rock formations to block their vision. What appeared in front of them was an extremely empty underground world.

The whole underground seemed to be hollowed out. Tall buildings appeared in front of them. The surrounding rock walls were full of high-speed elevators up and down, and above the rock walls were all kinds of artificial light, making the whole underground space as bright as day.

Win Rui said, "the whole Beihai city is an underground fortress dug 1500 meters underground. It is divided into seven floors. Each floor can be regarded as a city. What you see now is the first floor."

Zhou Bai looked at the scene outside in surprise and said in his heart, "how much effort and materials it takes. I'm afraid this place is more expensive than Donghua city when it's sold."

Win and destroy then said, "four days later, the big match of the four schools will officially begin. I'll take you to our resting place first. This time, all the special courses have come to participate and watch the war, and the principal has also come."

"Zhou Bai, I know you are very good, but the big ratio of the four schools is a team competition, and you can't win alone. You must unite and cooperate with other students."

Zhou Bai nodded, "by the way, what about the dream? Is she back?"

Win Zao was slightly stunned and shook his head, "if Meng Ruo Cun doesn't participate in this four school competition."
