Although the two reached a cooperation on the surface, Chu Yu knew that Qian Hu's words could be half believed.

But it doesn't hurt, Qian Hu needs Chu Yu's combat power, and Chu Yu needs a place provided by Qian Hu where he can meditate and cultivate, use each other, and take what he needs.

As for half a year later, no one can predict what will happen.

But a big mess must be inevitable.

Chu Yu declined Zhang Dahan's escort and came to Senior Sister Bai's residence, and the two began to study the world map of Lingyuan Star.

"Senior sister, you said that if you ask the monk to draw such a map, is it feasible?" Bai Yuejian was also shocked by the modern technology of the celestial civilization, and stared at the map for a long time.

"It's doable, but it's hard. Even if the Yuanying Monk was allowed to use the method of divine consciousness rubbing to travel all over Fengyuan, it would take decades of effort to draw the mountains, rivers, rivers and seas on the entire planet one by one, and it was not guaranteed that all of them would be right.

Moreover, a monk of our level is busy with his own cultivation on weekdays, so how can anyone put in the hard work to do this. ”

"That's right. Alas, I once thought that when I reached the peak of Yuanying, I was already the master of one party, and there was no opponent under the gods. Now on this spiritual source star, I know how big this world is, and my former self is the real frog at the bottom of the well. ”

"It's okay, senior sister, even if we are the frogs at the bottom of the well, we are the ones who are the leading frogs! Now that we have jumped out of the well, we are not necessarily worse than others. ”

"I hope so. By the way, I found this book from the old man surnamed Mo earlier. ”

Chu Yu saw that the book in his sister's hand had nine big characters written on it: "Introduction to Geometry in the Fifth Grade of Primary School".

“？” Rumors are confused.

"There is some knowledge of using numbers to analyze figures, which is beneficial to my research on formations. I heard that in the city of celestial beings, this is only something that children learn, what kind of middle school and university do they have...... It's like our private school there. I don't know what kind of opinion they have about 'geometry' in their university, maybe they have something in common with the ancient formation......"

Chu Yu hurriedly stopped the senior sister from continuing to discuss the formation, and the two turned their thoughts back to the map.

The land and sea area of Lingyuan Star are similar, with a total of three continents, and the Beishan Mine is located on the largest of them.

To the west and south of the mine are vast wilderness, to the north are long mountains, and to the north are the snow-covered polar regions.

Running down from a high mountain to the north, there is a long river that flows eastward called the "Mirror River".

To the east along the Jing River, there are a number of new cities, scattered towns that are connected together to form urban agglomerations until the river flows into the sea.

The names of the small cities variety, but the largest city is in Haikou, called Tianhai. These small cities are all under the jurisdiction of Tianhai City, collectively referred to as the Tianhai area.

Nominally, the Beishan Mine is also part of the Tianhai area.

If Chu Yu learned to shop online, then her address should be written now: Konghai Galaxy, Lingyuan Star, Tianhai Region, Xiaoyucheng, Beishan Mine.

Little Fish City can not remember, huh.

The two discussed for a long time, and there was a big disagreement on the route of escape.

"Senior sister, you are usually quite clever, why are you so confused now! If you enter the city, with the means of heaven and man, any technology may be able to easily find you! ”

"Going into the mountains is a dead end, senior sister! Hidden in the city, not to mention that if we don't have contact with heaven and man, when will we be able to buy a mobile phone? Well, I mean learning technology. ”

To the north or to the east, the two argued for a while, and finally reached an agreement, first north and then east.

The route has been decided, Chu Yu carefully put away this map, and went to the mine as usual the next day, waiting for news from Qian Hu's side while digging.

She made sure of a lot of things through the skinny monkey.

For example, the transfer in Qian Hu's mouth is indeed true, and most people know it, but it is not as accurate as the date Qian Hu said.

"Sister Chu, there are people in the Xiaoman Gang who can untie the slave ring, I have also heard about this, and it is becoming more and more evil, saying that there are people in the mine slaves who want to rebel!"

"Rebellion? Does any of the chiefs know about this? ”

"Then I don't know. If the surname Zou really knows, I don't know how much trouble I will make! ”

This must have been facilitated by Liu Yun and some of the forces she represents, but what good is it for them to do so?

"In short, Sister Chu, you should be careful, now everyone in this mine is in danger, and they don't want to catch fire."

The storm is coming. Chu Yu naturally wouldn't get involved in these things, and her main task now was only to cultivate and cultivate.

But she didn't expect the fire to come so quickly.

First, many people protested in the canteen that there was too little food and were suppressed by the chief; Then it was rumored that someone gathered in the scene to make trouble, and was directly wiped out by Zou Fatzi, and many people died.

When I waited until the next day, I saw that Liu Yun was walking beside the fat man, the slave ring around his neck had already been removed, and he had changed his clothes, with a proud spring breeze on his face.

What a "way to untie the loop"!

Looking at Liu Yun with two celestial guards showing off her might in the shelter, Chu Yu finally understood what kind of calculation she was playing.

first spread rumors, and then pacified the trouble, this operation naturally made her gain the trust of Zou Fatzi, and turned from a slave to a master.

This Liu Yun is willing to feed the tiger with his face, but he is also a character.

This also made Chu Yu more cautious about this Elder Liu. That day, Chu Yu refuted her face, and the ghost knows if this person will hold a grudge.

Can you hide or hide, now Liu Yun has become a celebrity in the eyes of Zou Fatzi, and it is really unwise to provoke again.

After a few days of nervousness, Qian Hu finally came to the news.

After Chu Yu and his senior sister rendezvous, they slipped to the entrance of Mine No. 1 in the night.

The large entrance to the cave was blocked by planks and seals, and the tunnel looked even more eerie in the darkness of the night.

The two of them cautiously flipped over the enclosed objects and headed into the depths.

Chu Yu had already prepared, took out a flashlight from his clothes, and swept it around to illuminate it.

"Where did it come from?"

"Stole."

“……”

"I also snatched a pair of watches from Xiaohuzi, senior sister, look! It's pretty too, why don't you try it on? ”

"Okay, okay, I don't wear it. Let's go. ”

Nothing to say for a while. In the dark tunnel, only the footsteps and breathing of the two could be heard.

The deeper you go, the hotter and hotter the air becomes, with the occasional audible ticking of water droplets sliding down the top stones.

After less than ten minutes of walking, the two men were blocked in their way - the main road was blocked by piles of boulders and wooden blocks, and it seemed that the two of them could not clear it alone.

"It seems that this is the reason for the closure, and there must have been a landslide before." Senior Sister Bai gently tapped on the rocks.

"I think I can blow it up with spirit stones." Chu Yu rolled up his sleeves and was about to rush over.

"Stop, stop, you want this place to collapse! There should be a side road nearby, let's go another way. ”

The Netherworld Technique that the two of them are cultivating now has been improved by the Netherworld Technique, and one of the conditions for the cultivation of the Netherworld Technique is that it requires an environment with heavy Yin Qi. If you want to find a sufficient amount of Yin Qi, the deeper the cave, the better.

That's why they keep going deeper.

Chu Yu and Senior Sister quickly found a winding branch road on the right side of the main road and walked towards the depths of the formation.

"Senior sister, the purity of yin qi here is very high, we should have found the right one!"

"Well, although it's not as good as the 'Yin Absolute Valley' in our sect, it's enough." Bai Yue's face also showed joy.

"This is a broken mine, how can it compare to the holy land in our sect. Alas, when it comes to the sect, I miss my cave again...... I don't know if Xiao Ling is doing well, she shouldn't have been captured by the heavens. ”

"Your spirit snake hasn't been cultivated to the point of transformation, so you must not be able to hold the mine manuscript." Seeing that she was in a good mood, Bai Yue actually made a joke.

"Oh yes, when it comes to this, I thought of it a long time ago, the method of lifting the slave ring ......" Chu Yu whispered on the face of the senior sister.

“…… If you don't say it, I forgot about it! Or you little girl has a lot of ideas. ”

"Hehe, so it's not a big deal about this Tianren technology!"

The two laughed and continued on their way, and soon reached the end of this branch.

"Alright, this place is deep enough, let's retreat here. It's a pity that there is no Bigu Dan, otherwise it can save the time of daily eating. ”

"It's okay, it's good to wait until you return to the foundation building realm, and you can go without eating for a few years."

"You said it lightly, don't forget that we don't even have a level of qi refining right now. Since Qian Hu said that the exchange is indeed a thing, we will limit it to half a year and try to make as many breakthroughs as possible! ”

Half a year is not short, but it is not long for cultivators. When you reach a high level of practice, a retreat can be years.

Time is of the essence, and every second counts. Chu Yu and Senior Sister sat opposite each other, their eyes slightly closed, and their minds gradually immersed in cultivation.

Bai Yuejian arranged three improved small maze arrays in advance to prevent accidents. In this Beishan mine, no other cultivators with mana have been found, and in the depths of the abandoned mine, they are not afraid of being discovered, and the exercises are running at full capacity, and the efficiency is more than a step faster than before!

The rolling yin qi poured into the body like a tide under the operation of the spirit formula, rushing to the acupoints and expanding the veins, swimming through the body, sinking in the dantian, and turning into a stream of origin spiritual power!

Chu Yu was surprised to find that after passing the threshold at the beginning, the cultivation of this spirit spirit technique had become more and more "silky", and the speed was amazing.

If you keep it up at this rate...... In less than half a year, you can reach the first level of gas refining, and even higher!

Whether it was because of the special practice of the Soul Spirit, or because the celestial beings on the spaceship had accidentally helped to transform the body, it was unknown.

Time flies......
