In fact, the above worries are also unnecessary. The magic weapon used by the cultivators was not tempered day and night, and the unit cells inside the magic weapon were filled with aura. It's just that ordinary cultivators don't know why they want to refine magic weapons. Therefore, to see the magic weapon of the cultivator, you only need to look at its physical properties. In other words, the above set is still applicable to the Dharma Weapons of cultivators.

Besides, after Yun Zhong learned the secret of the refining weapon, he immediately began refining the flying sword. He has a lot of refining materials in his hands, and the materials for a flying sword must be more than enough, plus he knows the secret of the magic weapon, so Yun Zhong should be able to refine a ninth-rank immortal weapon. But that's not the case. It's one thing to know to say it, it's another thing to do it. Yunzhong put all his energy on moving the unit cell, but after a long time, Rao is Yunzhong's deep skills also felt a little unbearable. In the end, only the refining of the flying sword was made to the fifth rank, and it was a so-so immortal weapon. This is a genuine immortal artifact, and there is a saturated aura in it.

It seems unscientific. Yun Zhong couldn't help but think like this, if the magic weapon could be mass-produced, and then the cultivator could inject the aura into it, wouldn't the immortal weapon be mass-produced. However, the various methods of processing materials in modern society cannot meet the requirements at all, and there is no quenching, tempering, annealing, normalizing, in any case, that can achieve the purity of the unit cell to one thousandth. This is countless times lower than the percentage content of the lowest magic weapon. Yun reimagined that in order to mass-produce magic weapons, it was imperative to change the existing production model.

The time at school is always very short in Yunzhong's opinion, and it's time for the holidays. Yun Zhong decided to go to Chen Fengya's hometown, Xian County, Hebei Province, this time to see what the ancient tomb where Yin Danjue was found was there. Before Weipu went home, he was still a disciple. Yun Chongqian said everything, and finally sent him away.

Chen Fengya knew that Yun Chong had a flying sword that could fly to the sky, so he didn't want to buy a train ticket this time, and kept begging Yun Chong to take the flying sword back. Yun Zhong was tempered by him, and in the end he just agreed. The speed of the flying sword is also really unambiguous, and it didn't take long for it to come from Changsha to Xian County. Chen Fengya found his location in the sky, and then pointed out a hidden place for Yun Chong, so that the two of them fell to the ground.

The two of them were not in a hurry to go home, and slowly groped their way to the location of the ancient tomb. Since it had been almost ten years, Chen Fengya couldn't quite remember the exact location of the ancient tomb, so the two of them were looking for it while walking. Finally, in a piece of barren grass, he finally found the tomb robbery cave discovered by Chen Fengya.

Yun Zhong drilled into the ancient tomb one by one, and Chen Fengya followed. Since the ancient tomb and the outside were figured out, the two of them didn't feel depressed. But there was no light source in the tomb, it was pitch black, and nothing could be seen. The clouds are so heavy that they can't do it, but Chen Fengya's skills are too shallow, and he only feels that the things in front of him are vague. Seeing this, Yun Zhong took out two night pearls the size of a fist from the Immeasurable Qiankun Ring, and then placed them in the corner of the ancient tomb. The Night Pearl glowed white, and everything in the ancient tomb was presented to the two of them.

The marble tomb floor and walls are made of hard stone. As you can see from the walls, there should have been four night pearls in it, but they were later stolen by tomb robbers. There is a platform inside the tomb, which is more than a meter higher than where you first entered. Above the platform lay a coffin, which had no lid. In front of the coffin is a stone tablet with the life of the owner of the tomb.

The owner of the tomb was a woman, who seemed to be no more than twenty-five years old when she died. Strangely, the cause of death of the owner of the tomb is not stated on the tombstone, but only a lament for the untimely death. Yun Zhong walked onto the platform and looked at the tomb owner in the coffin. I saw that her face was normal, as if she was still alive. It's just that as soon as he got closer, he felt a chill coming from the corpse, and he didn't know if Chen Fengya noticed it back then. Yun Zhong knew that this chill was the reason why the tomb master had cultivated the Yin Dan Jue. Fortunately, she was a woman, and her yin qi was originally heavier than that of men, so she lived until she was twenty-five years old before she died. If it weren't for Yun Chong's timely discovery, I'm afraid that Chen Fengya wouldn't have lived to be twenty years old.

Chen Fengya stood beside Yun Chong, looked at the tomb owner, thought for a while, and then said, "Why has she been dead for so long, but her body has not decayed at all, as if she is asleep." ”

Yun thought for a while and said, "Cultivating people is also human. Since the owner of the tomb is dead, and the body still shows no signs of decomposing, there must be some embalming treasure in her body. After speaking, Yun Chong's eyes flashed, and then he couldn't help but let out a soft "huh".

Chen Fengya hurriedly said, "What's wrong?"

Yun Chong said: "I didn't expect the tomb owner to hold the evil bead in his mouth, no wonder, no wonder." ”

Chen Fengya has been groping by himself all these years, and he doesn't know anything about the things in the cultivation realm, and naturally he doesn't know about the evil beads. So he asked, "What is the use of the evil bead, is it used to prevent corrosion?"

Yun Zhong said: "I can't help it. As long as the bead is held in the mouth before dying, then the person can continue to live until there is a cure for her. It's a bit like today's freezing technology, but it's more sophisticated. ”
