One by one, the doors opened …

　　The more he read, the more surprised Tang Huan became.

　　In some of the rooms, there were items such as hammers, pincers, and other tools for forging weapons. There were also various pills and herbs, but Tang Huan had seen most of them with various gems that possessed miraculous powers. In one of the rooms, Tang Huan almost froze the moment the door opened. Compared to the gem, the melted "Cold Jade Stone" was not even worth mentioning.

　　"Creak!"

　　Tang Huan pushed open another thick and heavy door, and a scorching heatwave immediately a.s.saulted his face, causing his clothes and hair to feel as if they were about to ignite. It was a good thing that the wood separating the palace was not ordinary, if not, the entire room, and even the entire palace would have been turned into ashes.

　　He moved to the door and peeked his head out. Unexpectedly, there was a millstone-sized ball inside the room.

　　The whole ball was bright red, crystal clear, and exuding a strong heat.

　　"What is this?"

　　Tang Huan suddenly realized that the "Nine Yang Divine Furnace" in his dantian was ready to make a move, and the "True Fire" in the cauldron was also flickering. This sudden change in events allowed Tang Huan to faintly understand that the heat emitted from the ball might be able to cause his "True Fire" to increase quite a bit.

　　What should he do?

　　Tang Huan thought for a while, then his eyes suddenly lit up. The old man guarding the door only said that he could not bring anything out, he was only absorbing the heat from the ball, and did not take the ball out … Of course, this couldn't be said to be violating the rules of Hidden Edge Hall.

　　Laughing, Tang Huan stripped off his clothes, went into his room and closed the door.

　　"Huh?"

　　A smile that was uglier than crying appeared on his skinny face, "This kid has good eyesight, he actually chose the room where the 'Mysterious Sun Pill Stone' is located. The 'Mysterious Sun Fire Essence' contained in the 'Mysterious Sun Pill Stone' is indeed able to increase the 'True Fire', however, this thing cannot be absorbed too much, otherwise, it would be harmful. I wonder how long this brat will be able to last?"

　　"Wu, he is only a first rank Martial Disciples with four spirit veins open. It would already be quite good if he could stay inside there for half an hour."

　　The short elder lightly stroked his long beard, then closed his eyes.

　　Inside the small room, the naked Tang Huan was already sitting cross-legged.

　　The closer he got to the ball, the hotter it became. Even with the fusion of the true flame, the intense heat still made it difficult for him. In just a few breaths of time, he was like a cooked shrimp.

　　Tang Huan forced himself to calm down and concentrate. Soon enough, a ball of "True Fire" emerged from each of his palms.
