They had to admit that Ling Feng's powerful cultivation and terrifying strength, while Ling Feng looked at the entrance of the cave, but said something that shocked everyone: "You guys go in together!" The four of them were very surprised, they didn't expect Ling Feng to let them go in too, you must know that this is the treasure of the Thunder Emperor Zhang Shaojun, a place that countless monks and martial artists want to enter, and they can comprehend the Great Dao of the Thunder Emperor!

And Ling Feng said this as if one person won the prize but shared it with several other people, the next three tests were passed by Ling Feng alone, they only did not help at all, but Ling Feng let them go in together, such a mind, I am afraid that no one in the whole world can match!

"Thank you, senior!" said a few people very excitedly, they came here and were trapped for a hundred years just to get the Thunder Emperor's treasure, and now their wish has come true, to be exact, it was fulfilled by Ling Feng!

After that, Ling Feng walked into the cave, and the four of them followed closely behind Ling Feng, they walked along a road towards the front, it was very quiet, except for their own footsteps, there was no sound at all!

After walking for about a few minutes, they heard the sound of water, and continued to walk for about a few dozen steps, they walked out of this road, and in front of several people there was a space, and in the center of the space was a small pool, a small pool with countless lotus flowers!

The lotus flower is very large, there is no problem at all for a person to stand on it, in this space, it is full of powerful heaven and earth aura, especially near the pool, it is even more terrifying, everyone feels it!

In another place in the space, there were two five sons, one was where Zhang Shaojun rested, and the other Ling Feng guessed that it should be something left by Zhang Shaojun!

Ling Feng walked towards another room, he pushed open the stone door, and was stunned for a moment, this room was actually an alchemy room, and there was a huge Dan furnace in it, which looked very terrifying!

"I didn't expect it to actually be able to refine pills!" Ling Feng didn't expect that this young army would actually be able to refine pills, not only did he smile, but there was also a spirit gathering array near this Dan furnace, the Dan furnace was full of heaven and earth aura, Ling Feng suddenly thought that if the elixir was refined through such a terrifying aura, then it must be of the highest grade or the best!

In order to break through, Ling Feng could use the Dan Furnace in front of him to refine the Dan, otherwise all these spiritual qi would be wasted!

Then Ling Feng was in front of the Dan Furnace and took action, his hands continued to emit chaotic aura, entering the Dan Furnace, and began to make the heaven and earth aura inside become active, and several onlookers were puzzled, they knew that this was the alchemy room, but what was Ling Feng doing?

"What is Brother Ling doing?"

"Do you think he's doing alchemy?

"What are you talking about, Brotherhood Ling will do alchemy?" They were very surprised, alchemy is very difficult, in the whole of China, alchemists are very rare existences, because the alchemy room wants to control the aura to the extreme, and it also needs to learn the fire attribute to control the fire, and the most important thing is that the magic of alchemy determines the quality of the elixir!

Ling Feng ignored the surprised expressions of several people, but stood on the edge of the Dan furnace, running the Chaos Black Flame in his body, and then with a wave of his hand, the Chaos Black Flame had already fallen under the Dan Furnace, and began to burn continuously, Ling Feng began to refine the Dan!

Alchemy also attaches great importance to the quality of flames, and Ling Feng's Chaos Black Flame is the top-level flame in the entire heaven and earth!
