Unconsciously, Zhou Shu had been on the back crossing line for several days.

He guarded the back crossing line vigilantly, and was also shocked by everything on the back crossing line.

Mountains, lakes, deserts, rivers, and even grasses, trees, mud and stones have a mysterious meaning. From the perspective of a sword, it means that there is a sword everywhere, and everything in the world can be used as a sword. Then, there are formations everywhere across the boundary, guiding the sword intent in the world and all things in the world one by one, like a river returning to the sea, and finally concentrated in the furnace.

It seems that the furnace is not fire, but the sword intent between heaven and earth, nor is it Ou Ting making a sword, but the heaven and earth making a sword.

Or the reason for the formation was activated, the furnace was no longer visible at this time, surrounded by flames, and the sound of forging could be heard from time to time. However, the sound was not noisy, but it was as clear as a song, which made Zhou Shu feel quite enjoyable.

"Heaven and earth are the furnace, and they are born naturally. The master is the master. This is Zihen's fortune and Caiying's luck."

Zhou Shu nodded slightly, and the expectation in his heart became more and more.

Suddenly, Zhou Shu stood up and looked into the distance, with a hint of chill flashing in his eyes.

Someone is coming again.

In the past few days, he had driven away several people, and they all saw that the sword formation that crossed the boundary was gone. They thought something had happened and wanted to come over to find out the truth. Of course, Zhou Shu would not allow it. He was polite first and then soldiers. Most of the people knew Zhou Shu's power, and one who didn't know soon also knew.

As the figure got closer and closer, Zhou Shu stumbled slightly, "Is it him?"

Although he knew each other, Zhou Shu would not relax his vigilance and quickly met him and blocked him from the boundary.

Zhou Shu frowned, "Come on, what are you doing here?"

"I'll help you, Brother Zhou!"

You Chongzhi had a look of dust on his face and his eyes flashed, showing that he was quite excited.

Zhou Shu said in surprise, "Help me? I don't need anything to help."

You Chongzhi was stunned for a moment and soon understood, "Brother Zhou, don't you know yet? You will be in trouble soon after crossing the line!"

Zhou Shu seemed to be thinking, as if he felt something, "Let me tell me."

"A locust tide!"

You Chongzhi said things urgently, but he didn't notice that Zhou Shu's face changed a few times.

So that's it, so that's it.

It is a good trick to kill people by using a knife. This locust tide is a knife. If he dies in the locust tide, the Ten Thousand Soul Sect will not be criticized and punished. However, for the sake of himself, he would have to let forty-seven Acropolis be buried with him. This is too expensive.

Does the city lord hate himself so much? Or is it for another reason?

Of course, Zhou Shu would be fine as long as he went back to the main city, but now, he had to protect the back and cross the line, for the sword, and for Ou Ting.

Ou Ting faced a locust tide for himself to forge his sword. How could he suffer a catastrophe?

No matter how difficult it is, I have to fight.

Zhou Shu looked at You Chongzhi with a calm expression, "Thank you, but you should go back. You can't help me alone. Moreover, if you come, it will affect Bai Yujing's status in Crescent City, which will be very unfavorable to your You family."

"Don't worry about this, just me will not affect anything, and it is supported by my second brother, hehe."

You Chongzhi smiled a little proudly, "Brother Zhou Dao, I am not here to help you alone. I have gathered people from the Three Realms, and of course there are many true immortals in the Crescent City. There are more than 2,000 in total, so many people can definitely help!"

"More than two thousand people?"

Zhou Shu had many accidents.

You Chongzhi nodded and said, "It was my second brother who reminded me to find people. It was not difficult to find them. I found that there were actually many true immortals who wanted to resist the locust tide and gain the benefits of resources from it. However, the Crescent City generally did not arrange them because these things were done by the Golden Immortals. Many true immortals could only do it spontaneously if they wanted to go. As a result, they often fed floating beasts. This time I said I wanted to organize them, and many people voluntarily signed up. I couldn't help but want them!"

Zhou Shu felt aroused. If there were so many people, he might not be able to defend himself and cross the line. "You can talk about the locust tide in detail."

"I won't talk about it anymore. There are some jade slips here, so you can take a look."

You Chongzhi handed over the second brother's jade slip, "Although the locust tide is not a secret, the specific information is only available in the management of the Crescent City. I don't know how my second brother got it. It's very detailed and useful. Only after reading this can I have confidence."

Zhou Shu read it roughly, felt aware of it, and said slowly, "Thank you, your second brother."

Unexpectedly, in the critical moment, Bai Yujing stretched out his hand. Linglong Pavilion must have known what was going on, and they knew earlier than anyone else, but they had no movement. They even had the idea of ​​notifying Zhou Shu for a while, and they were waiting for the locust tide to swallow the place.

Although I don’t have any friendship, I’m still a little disappointed from this incident.

You Chongzhi nodded seriously, "Yes, my second brother is really attentive. He helped me think of everything I didn't expect."

Zhou Shu smiled slightly, "Thank you even more, thank you for rushing, let's go down first."

"What do we have to thank for?"

You Chongzhi frowned deliberately, but he felt happy in his heart, "Those true immortals will arrive soon after the day after tomorrow, and the locust tide will be in forty-five days. In short, we will start preparing now. I have a plan. That's it... Brother Daoist, do you have any opinions?"

Zhou Shu nodded slowly, looking at the jade slip, as if he was in deep thought.

You Chongzhi waited quietly, turned around and looked at the furnace surrounded by flames, as if thinking, "The point is the place where the master is making swords? Brother Dao, let's protect this place and never let the locust tide hit, otherwise the master and the sword will be in trouble."

Zhou Shu's expression was calm, "Of course, but every place that crosses the line is very important."

The world is the furnace, and the key to making a sword is to cross the boundary after the entire rear. Zhou Shu is very sure that no matter which place is damaged, it will affect the effect of forming a sword in the end. If possible, it is best to keep the entire rear cross the boundary intact.

You Chongzhi nodded slightly, "There is only 50,000 radius behind the border. We have enough people and we should be able to do it."

Zhou Shu was silent, but there was a tide in his sea of ​​consciousness.

Do what he is best at.

The deduction calculations are carried out quickly, and after crossing the boundary in the sea of ​​consciousness, they are divided into many small pieces, and each piece is complicated to operate, such as playing a chess game, how to set up a formation, how to build defenses, how to use the real immortal... Soon there were hundreds of plans.

Afterwards, many information about floating beasts was inputted, and a huge locust tide took shape in the sea of ​​consciousness, and began to impact the latter cross-border.

Continuously simulated one battle after another.

These battles end in an instant, and all they get is the result, that is, a string of numbers.

Although there are inevitable errors every time, as long as you simulate enough times, you can get close to the reality.

I don’t know how long it took, but it repeated many times. Several near-perfect plans were displayed. Zhou Shu still did not stop. He continued to make detailed modifications around these plans, and simulated them again and again until the final result was obtained.

According to the results, it is impossible to achieve 100% perfect unless unexpected situations occur.
