"Li Aoxue is your sister... Aoxue... Aotian. Alas, I haven't thought about it for a long time. In this way, Li Daoyou is half of my own in Xianling cave. Ha ha ha ha."

Obviously, he didn't know the relationship between Li Aotian and Li Aoxue in advance. Li Qianhe laughed awkwardly.

"Don't say it's useless. Let's talk about the origin of the blood coffin. To be honest, since the first world war between xuetianzhong and me, I have been very interested in him, including the so-called Wumen."

Li Aotian doesn't plan to talk to Li Qianhe any more. He points to the blood coffin beside him.

"This blood coffin is called Yinming blood jade coffin. I don't know its specific origin. It's not only me, but also the successive leaders of Xianling cave."

"The reason why this coffin is extremely important to our fairy cave heaven is that our mission of Fairy Cave heaven is to protect this coffin well and not let it fall into the hands of outsiders. To be more clear, it is not to let this coffin fall into the hands of the people in the witchcraft sect."

Li Qianhe said solemnly.

"It's really related to Wumen, which I expected. Is there any secret in the blood coffin?"

After taking a picture of the bloody coffin beside him, Li Aotian asks curiously again. He has already tried to explore the bloody coffin with his divine sense, but the bloody coffin can isolate the divine sense. Even with Li Aotian's keen divine sense, he can't get a glimpse of the situation in the coffin.

Hearing this, Li Qianhe shook his head: "I really don't know, because we haven't opened the coffin, and we can't open it at all."

"Can't open... Is it so hard?"

Li Aotian said, and he pressed his right hand on the lid of the coffin. He wanted to push it away with brute force. But what made his face slightly changed was that he pushed it on the lid with his powerful physical strength. It was like a bull in the ocean. It didn't work at all.

"Don't try. Although Li Daoyou's fighting power is amazing, even senior Jiang Li can't help it. According to senior Jiang Li, it may take the fighting power of the holy rank to open the coffin."

Li Qianhe was not surprised by the result of Li Aotian's brute force pushing the coffin, he said with a smile.

"The fighting power of the holy rank... It seems that this coffin has a bright future."

Li Aotian muttered to himself.

"Yes, I'm sure it's not small. My sea blue star is a star of three-level cultivation. If you practice on this star, you can reach the peak of the Taoist king, and you can't cross the threshold of the holy rank. Therefore, according to the conjecture of the past strong people in Xianling cave, this coffin is likely to come from abroad."

"Oh, yes, we can't rule out that it was written by the extraterritorial powers after they came to our sea blue star, but it doesn't matter to us. Our responsibility is to protect it well and not let it fall into the hands of outsiders, especially the people in the witchcraft sect!"

Li Qianhe said firmly.

"There's another point I don't understand. Why did you bring me to the outer cave when you explained to me the origin of this blood jade coffin?"

Li Aotian said strangely.

"I came to the outer cave because of the connection between the blood coffin and this place. Li Daoyou has seen a lot. Maybe he can guess why this place is like this?"

Li Qianhe asked with a smile.

"Well, all kinds of smells here are complicated and chaotic, especially the blood evil spirit, corpse spirit, dead spirit and Yin spirit. If my guess is right, it should be an ancient battlefield. Of course, it may also be a place where a large number of corpses are buried. Can I guess correctly?"

After hesitating for a moment, Li Aotian asked.

"Li Daoyou is really powerful. You can see that. You're right to guess that the outer cave is indeed an ancient battlefield, and there are a lot of corpses buried underground!"

Huang said with admiration.

"That's true... Did you go underground to explore?"

Li Aotian said unexpectedly.

"Well, we'd like to, but it's not that easy. To tell you the truth, there are a lot of prohibitions and arrays under the ground. Let alone us, even senior Jiang Li can't get into the bottom of the earth."

Li Qianhe sighed.

"Since you can't get to the bottom of the earth, how do you know that there are a lot of corpses in the ground, and how do you know that this is an ancient battlefield?"

Li Aotian asked.

"We don't need to confirm this at all, because it was said by the first generation leader of Xianling cave. It has been handed down to this day."

Li Qianhe explained.

Li Aotian frowned: "the first generation leader? How long has it been since the establishment of your fairy cave? "

Li Qianhe shook his head: "I can't remember it clearly, but it must have happened in tens of thousands of years. The first generation leader of our Xianling cave is named Ying Zhen. It's said that he is a saint level strongman from outside China. However, we don't know when he was, because it's too long ago."

"Ying Zhen? Ying... This surname is very rare... "

Li Aotian muttered to himself.

"It's very rare. At least in ancient China, I haven't heard of a few people surnamed Ying, but I can understand that after all, he comes from outside China. The fact that there are few people surnamed Ying in Hailan doesn't mean that there are fewer people in other cultivation stars."

Huang Zheng doesn't think so.

"Yes, by the way, you just said that this jade coffin is related to this place. What is the so-called connection

Li Aotian's topic changed.

"Li Daoyou, follow me!"

With no direct explanation to Li Aotian, Li Qianhe rises in the sky and flies away in a direction. Seeing this, Li Aotian and Huang Zheng follow up.

Although the outer cave of Xianling cave is much bigger than the inner cave, it didn't take much time for Li Aotian to get to the destination. They came to a huge bloody altar built in the desert.

The whole body of the blood altar is round, and it is nine stories high. The area of the lowest layer is nearly 100 feet, and the smaller it goes up. The ninth layer at the top is about 10 feet wide. In the center of the altar, there is a long strip-shaped gravure. It seems that there should be something here.

Looking down at the whole altar from the middle of the sky, people feel extremely magnificent. After all, the whole outer cave is a desert with thousands of miles of red earth. Now suddenly, such a huge altar appears, which is particularly eye-catching.

Li Aotian was not attracted by the magnificence of the bloody altar. As soon as he arrived at the altar, his eyes were fixed on the large number of gold and silver runes engraved on the altar.

Li Aotian recognized these runes at a glance. They are commonly used by Buddhist practitioners. It is precisely because there are a large number of Buddhist texts on the altar that the whole altar exudes a faint breath of Buddha nature
