Originally, in Tang Letian's opinion, this was a big problem, at least a time-consuming problem, but it is no longer a problem. From this point of view, we can see that the ancients were not stupid at all. The reason why Tang Letian performed better and knew more was that he stood on the shoulders of countless ancient people who were superimposed.

"We need all the alchemists to have such a refining disc. As for monks, they don't need it. They can absorb real energy, but the dosage is not large. My Kunlun Sect has more than 870 alchemists. The alchemists make more than 10 or 20 more per month, which is almost enough for monks to use. In this case, the sect will trouble the sect to build more than 800 refining discs. In addition, refining crystals will produce some miscellaneous air, which are harmful. There is no problem in refining one or two crystals, and there is no problem in refining them in an open area. However, under this ground, those miscellaneous airs have nowhere to be discharged and will gather more and more. People will be polluted by miscellaneous air when walking, sitting and lying down. Fortunately, those monks will definitely not be able to withstand the miscellaneous air, so they have to think of some ways to deal with all the miscellaneous air."

Tang Letian's words made several excited elders and Kunlunzi quiet down.

The reason why the crystals they dug out was absolutely harmful is that there were some unknown things in the crystals that would interfere with monks and kill mortals.

The refining crystal extracts useful real energy from it, and the remaining harmful substances will naturally scatter in the surrounding space. This underground space is not too big or small. If every alchemist extracts real energy, then the various harmful impurities released will fill the entire space in no time. This is indeed a problem.

Everyone fell silent and there was no movement for a moment.

Tang Letian really has no choice but to do this. In the future, a group of people will not be stuck in the ground to refine their true abilities. The situation in Kunlun School is very special.

To be honest, Tang Letian also thinks this problem is tricky. There is no way to deal with so much waste gas that is suspended in the air. If they do not need to close the entire underground road address, it is actually very simple. They open the underground road address every once in a while, discharge these waste gases and gases outwards, and exchange fresh gases, and everything will be solved. But the biggest problem is that after the underground road address is blocked, they will not be opened unless they already have the strength to fight against the puppet demons.

Tang Letian was thinking about how to discharge these waste gases, but Kunlunzi suddenly laughed and said, "It's no problem." As Kunlunzi reached out and grabbed a crystal stone companion ore, kneaded it, and soon another refining disc appeared in Kunlunzi's hands.

However, this power supply disk is slightly different from the power supply disk created by Kunlunzi. Some places seem to have completely opposite structures, and the talisman patterns on it are also very different.

Then Kunlunzi grabbed two refining discs, broke a crystal, and the two random power disks were buzzing and rotating. They could really be pulled away by one refining disc, and the remaining harmful miscellaneous air was pulled away by another refining disc.

Then one of the two refining discs showed a real energy bead, and the other refining disc was a turbid colored bead.

Finish.

Tang Letian looked at the turbid bead and fell into deep thought.

Tang Letian laughed, "I want to take a break, you can continue to study."

Tang Letian really didn't want to see Kunlunzi's smug appearance, so he turned around and left.

This incident tells Tang Letian a truth. There may be a huge difference between him and those alchemists, because he has gained thousands of years of knowledge out of thin air. However, compared with a guy like Kunlunzi who has reached the realm of divine travel, his advantage may not be too great, because these guys are too smart and surpass the cleverness of this era. If you reveal a little clue to him, he will understand the truth.

This is a very terrible thing. Originally, Tang Letian thought that talking to the ancients about building warships was a very ridiculous thing and a very boring thing. Because of the huge knowledge differences, many things cannot be explained clearly, but now, he feels that the differences seem to be less terrible and unattainable.

Since Kunlunzi is so smart, Tang Letian has no interest in wasting time and brains on this matter, and let them explore and study the mining of crystal stones by themselves.

The equipment he was working on was about to be completed, and then it would definitely surprise Kunlunzi's sarcastic goods.

Humph...

Tang Letian actually cared a little, caring that others were smarter than him, and Tang Jiuqu was better than him. Although Tang Letian complained a few times, he really didn't take it to heart. After all, luck is an external factor and cannot be changed.

When he returned to his residence, he saw Tang Cihang, Tang Rong'er, Yun Sheng and Zheng Yueru talking outside.

Tang Letian wanted to avoid it, but after thinking about it, he couldn't avoid it. Everyone lived nearby and could never meet each other forever. Besides, they should be waiting for him here, so they walked over immediately.

When Tang Cihang saw Tang Letian back, his expression became particularly unnatural.

Now the entire Kunlun Sect knows that Tang Letian is the reincarnation of the Nascent Soul Infant Sect, this is a great good thing for the monks of the Kunlun Sect, but for Tang Cihang, this is probably a great disaster.

Tang Cihang stood up and looked at Tang Letian. There was a complex emotion in his eyes, as if he was still thinking about who Tang Letian was.

Tang Letian couldn't stand such a gaze. It was not how terrible Tang Cihang was, but the kind of gaze that the father looked at his son but felt that he was looking at a stranger, which made people feel uncomfortable.

Tang Letian switched his mind for a moment. He fully remembered the memory of his master. He naturally knew the original behavioral habits of his master. He immediately smiled and said, "Old man, don't look at me like this. I am your son. Don't doubt this. Don't worry, I remember every stick you hit me since childhood."

Tang Cihang's mouth trembled slightly when he heard this, and then the sad worry finally resolved. He became excited. The old man's three disrespectful words made him feel comfortable. This was the name Tang Letian used to call him. This title was so friendly. When Tang Letian saw him a few times, he called him his father. Originally, he thought Tang Letian had grown up and matured, but later he knew that Tang Letian was the reincarnation of the Nascent Soul, which became a big bump in his heart and could not be solved. Now this kind name made Tang Cihang feel comfortable: "You... you, alas, I taught you a lesson for your own good."

At this time, Tang Rong'er said coldly, "Dad, I've told you a long time ago that this guy is my brother, how could it be someone else? You didn't see that he was living in the same room with his apprentice a few days ago. Is there anyone else in the world that is so shameless?"

When Tang Letian heard this, his face turned dark. Why is this little liar more and more like Princess Lizhu?

It is becoming more and more annoying and annoying, and it is not cute at all.
