Du Changsheng buckled all the gems, took out a bag and carefully put them in. Then he began to buckle the green gems. In this way, he buckled all the five kinds of gems: red, blue, yellow, purple and green. Then he left with Qi Tian.

"What's the use of these things?"

"You'll know in a moment."

When he came to the front of the underground palace, Du Changsheng suddenly stopped, sat on the ground with his knees crossed, opened the bag of red gems, poured out the gems inside, and suddenly a black flame burned on his hand.

These red gems immediately flew into the air. Du Changsheng waved his hand and directly covered the black flame. The remaining four kinds of gems were also made in the same way. Qi Tian looked at the gems wrapped in the black flame in the air and understood something.

"I seem to understand. Aren't you going to refine them and merge them?"

Du Changsheng nodded, but did not speak. At the moment, his mind was divided into five parts to check the condition of each gem. The red gem was the first to melt, and the red liquid was flashing. The other four kinds of gems were also melted into a pool of liquid one after another.

"Melt!"

With Du Changsheng's hands closed, the five kinds of liquid began to gather. However, as soon as they came into contact with each other, they gave off a dazzling light and an ancient breath. Qi Tian could not help feeling that he wanted to kneel down.

A moment later, the light dissipated, and a colorful column appeared in the air, surrounded by bursts of halo. The five colors were arranged in a clear order. Before Qi Tian had time to appreciate it, he was directly grasped by Du Changsheng.

"Don't look at it. It's the key to the power of the source. Now we can look for the power of the source."

"Well, it's really possible to find the source, but you're not one of us."

Qi Dun turned around, and his face turned red like lightning.

"Well

Du Changsheng spewed out a mouthful of blood and flew out directly. The column in his hand also rolled to one side. Qi Tian immediately went to pick up the column and began to play with it.

"Immortal God, why is your brain not working after you are reborn? It's so easy to trust people. "

"You know who I am?"

The immortal God looks at Qi Tian in surprise. If Qi Tian is still in the temple now, it's not strange to know his identity. But now that he has left the temple, why does he know his information.

"Are you surprised? To tell you the truth, when I saw you for the first time, I knew your identity. A little god level guy should have such a powerful spirit. Do you think it is possible? Plus the law of immortality, it's not hard to guess who you are

While talking, the blood devil emperor walked slowly in front of him, squatted down, stretched out a hand to hold his head, suddenly five fingers mercilessly grasped, and a soul was directly grasped by the blood devil emperor.

"I have existed since ancient times. It's easy to kill you. The reason why I let you escape again and again is to let you take out the key to open the source."

The immortal God's face became very blue. I didn't expect that I had been missed by the blood devil emperor for a long time. The reason why I didn't kill myself was to let me take out the key.

"Ha ha, although you have got the key now, you don't know the way to use it, so you still can't find the source."

"You're right. We can't find the source, but you can, can't you?"

"Do you think I'll tell you?"

On hearing this, the blood devil emperor did not have the slightest anger on his face. Instead, he suddenly took a look at the body on the ground, which had turned into the body of Mo Qilin. He reached out and pointed at the body. The blood immediately began to emerge, and the body dried up at the speed visible to the naked eye.

"It doesn't matter. You'll say it sooner or later."

The blood devil emperor suddenly released a stream of stinking blood, which gathered into a cage in the air. Then he directly threw the spirit of the immortal God into it, and the immortal God immediately sent out bursts of wailing.

When the blood devil emperor heard his wailing, his face even showed a look of enjoyment. This blood prison was made by him using filthy blood, which is very powerful for the damage to the spirit.

"I'll give you three days to think about it. If you don't plan to say it, I'll sacrifice you to the ancient god of Mount Tai."

After the blood devil emperor finished, he turned into a red light and disappeared in the same place. Qi Tian looked at the struggling immortal God in the cage, waved the key to him, and then came to him.

"The immortal God has come to such an end. You can't help but sympathize with people. You are really down in the world when you use the body of an animal."

Qi Tian said, releasing a magic gas, which directly blasted on the spirit of the immortal God. The spirit of the immortal god suddenly began to illusory. Qi Tian was also slightly stunned. He didn't expect that he was so vulnerable."I'm sorry, I didn't know you were so weak that you almost broke up your spirit, but This kind of feeling is really cool, the God of eternal life has become my prisoner

Qi Tian laughs and walks out. The immortal God's eyes are full of anger. At the moment, he wants to rush out and tear him up. However, the cage is a little bit of encroachment on his spirit. If he doesn't find a way out, he will disappear in three days.

Outside the cave, the blood devil emperor and Qi Tian stand on the ground, looking at the colorful key. The blood devil emperor takes it and puts it into his arms. Qi Tian just turns his mouth, but doesn't say anything.

"By the way, if the immortal God really doesn't say it, do you really want to sacrifice him to the ancient god of Mount Tai? How can we find the source then? "

"What are you afraid of? Now that we have the key, even if he doesn't say it, we'll go to find it by ourselves. Is there such a big place under the cave that we can't find it? "

"You have a point. What shall we do now?"

The blood devil emperor looked up at the sky, and suddenly a strange light flashed in his eyes. Qi Tian also showed a trace of evil smile when he looked at him. Although he didn't say anything, he could guess what he was going to do with the blood devil emperor for so long.
