At night, in the underground base, Zuo Zhicheng, who had finished today's cultivation, was wearing gloves and holding a blade about fifty centimeters long in his hand, and was constantly grinding with a whetstone. On the wall behind him, more than three meters long Chopping Red Dust and Extinction Yuan were hung there.

On the test bench, there is a large jar, and under the jar is a brazier, and I don't know what liquid is burning in the jar.

After grinding the blade in his hand a little, Zuo Zhicheng put the whetstone, then took a brand new silk cloth and began to wipe the blade to remove the oil stains and dirt on it.

The jar is sodium hydroxide, nitrite acid and trisodium phosphate, what Zuo Zhicheng is doing now is to do a layer of oxidation treatment on the blade, through guò sodium hydroxide, nitrite acid and trisodium phosphate composed of oxidant to form a dense and smooth ferric oxide on the surface of the dagger, which is equivalent to turning the whole dagger black, eliminating reflection, and can also play a role in preventing rust.

While the oxidant was waving, Zuo Zhicheng looked at the platform on the other side, where a mouse was squeaking in the cage.

I saw that his eyes were staring at the rat deadly, and his eyes revealed a cold color. Unfortunately, the rat didn't seem to feel it at all, and didn't react at all, and still crawled as before, squeaking a few times from time to time.

"Still useless?" While thinking like this, Zuo Zhicheng frowned, and a murderous aura surged out. The mouse's body stiffened, as if it had seen a cat, and it didn't dare to move, and even began to pretend to be dead.

Obviously, Zuo Zhicheng used the method of "Nourishing Qi Haoran" before, which was useless to mice, but with the murderous aura that he was used to, he could directly scare the rats.

Zuo Zhicheng slowly recalled the feeling of using the murderous qi just now, changed his mind again, and used the qi cultivation Haoran on the mouse.

Still doesn't work.

Until now, Zuo Zhicheng has been unable to break through to the realm of human appearance. On the contrary, the deterrent power of the murderous aura became stronger after he practiced the qi. And in his opinion, the role of murderous qi is very similar to that of human appearance, so he wants to use the feeling of using murderous qi to cultivate the cultivation of human qi.

After all, Zuo Zhicheng is from the modern era, and he has no absolute sense of respect for the ancients, cheats, and teachers, how to be effective and how to come. felt that the murderous aura was useful, and began to find a way to integrate that killing and cold will into the cultivation of qi.

"One more time."

Squeak squeak! This time, the mouse did not react, but turned its head to look in Zuo Zhicheng's direction, as if it felt something.

This kind of progress seems to be much faster than the way of simply cultivating Qi Haoran. Zuo Zhicheng guessed that it might be because of the cold killing intent, which was more suitable for him than pure tranquility, emptiness and the like, and it was also more able to let him swing his mind.

It's just that I don't know what changes will occur in the cultivation of Qi Haoran in the future after the cultivation of Qi Haoran is mixed with the murderous energy.

About half an hour later, Zuo Zhicheng used a large pair of tweezers to pick out the blade in the jar, and the blade turned completely black. Carefully wipe off the liquid little by little.

Zuo Zhicheng looked at the blade in front of him and nodded slightly, much better than the previous ones.

He then soaked the blade into another jar filled with a white solution, which was a co-boiled fat and sodium hydroxide, hydrolyzed into sodium fatty acids and glycerin. And high-grade fatty acid sodium is the raw material of soap, so this thing can actually be regarded as soapy water.

Zuo Zhicheng soaked the blade in soapy water to form a thin film of iron stearate on the surface of the blade to improve the corrosion resistance of the blade.

After ten minutes, the blade was taken out, the temperature was cooled, the solution was wiped off, and then the blade was loaded with a black wooden handle, and a long dagger with a pitch-black body had appeared in front of Zuo Zhicheng's eyes.

Slightly swept the dagger in his hand, Zuo Zhicheng nodded with satisfaction, the quality is naturally not as good as those military daggers used in the previous life, but in terms of the current environment, it is not bad to be able to use such a dagger.

After putting all the things away and putting them away, Zuo Zhicheng began today's translation work. In the first volume of the Tao Sutra, Zuo Zhicheng counted it, and there were about two hundred and eight life clusters.

Zuo Zhicheng remembers very clearly that when he was in the ancient tomb, the old man once said that there were only more than 200 recorded life clusters in the Western Wei Dynasty, which means that this Taoist scripture has recorded almost all the recorded life clusters at that time.

But at the same time, it also shows one thing, that is, this Taoist scripture is probably also compiled during the Western Wei Dynasty. It's not a secret book handed down from ancient times, otherwise there wouldn't be only two hundred records of the fate.

However, if the Southern Holy Gate is a sect that has been handed down from the era of gods and demons, then why is there only more than 200 records of life clusters in this secret book, shouldn't it be a record of all 1o24 life clusters?

Although he felt strange, the clues in front of Zuo Zhicheng were far from enough to judge these things, and he could only translate these two Taoist scriptures first.

However, so far, the translator has not found the part of the life cluster he has, the night sea, so there is no way to see if his life cluster is still there for the time being.

But an hour later, Zuo Zhicheng's eyebrows raised: "This is ...... Night sea? Finally found the location of his life record, Zuo Zhicheng was also slightly excited.

So about four hours later, Zuo Zhicheng pondered repeatedly, and barely translated the entire content of the night sea part. However, after all, this is related to his left eye, Zuo Zhicheng still plans to think about it for a few days, confirm that the translation is correct, and try the cultivation content little by little.

Zuo Zhicheng silently calculated the time, it was almost two or three o'clock in the morning, and he ended today's translation work. He put together the Taoist scriptures and the translations he had recorded, put them into a sandalwood box, lifted up a stone slab under his feet, carefully uncovered the silk threads at the entrance of the cave in the order he had set, and then put the sandalwood box inside.

If a stranger comes in and opens the slate directly, and reaches for it without seeing the silk thread, the concentrated sulfuric acid hidden in the cave will directly spill out, completely destroying the two Taoist scriptures and the translation materials.

Of course, for the sake of insurance, Zuo Zhicheng still copied a copy and buried it in the courtyard of Xiaolan's house.

After all, these two cheats are absolutely priceless treasures for people in this era, and Zuo Zhicheng can't be too careful.

So after hiding the two cheats, Zuo Zhicheng changed into a coat, put on a mask, and dressed himself up as a ghost fist again.

Next, naturally, I went to the place where the sun fire was, and found a way to investigate the reason for the growth of the other party's strength, and find out if there was any psionic food, and if so, where it came from.

Ten minutes later, a black shadow burst out of the small courtyard, like a ghost in the night, quickly streaked across the night sky, and disappeared into the vast night
