When Changyu had just recovered from the joy of obtaining an inheritance, he immediately realized a big problem:

Zhang Qing was in too much of a hurry before, but he didn't leave the means of emergency contact and the results of the treatment of drinking water.

That's not a good thing!

Zhang Yu picked up a spirit rune in his hand and hesitated, because he didn't have the means to contact Zhang Qing directly, and it would take a while to send the spirit rune to the Chashan Sect, and it would be even more difficult for the Chashan Sect to forward it again.

What's more, judging from the fact that Zhang Qing can't fiddle with the Biyan Ice Front Formation and walks away directly, Zhang Qing's face is not too thick, so he forwards it to let others know that Zhang Qing is afraid that he will kill his heart!

Thinking about it, although there must be a lot of danger during this period of time, Zhang Yu can only accept his fate, and the problem of communication means can only wait for Zhang Qing to be in a good mood or think of himself as a substitute ghost.

As for the water,

There is no shortage of food, I already know the general situation of the fire reef, Linggu and Lingyu have prepared a lot, and all kinds of seasonings can be stuffed as much as possible, but the meat depends on the demon beasts that emerge from the two spiritual veins under the fire reef, and they belong to the sky to eat.

But in terms of drinking water, Changyu really didn't prepare much!

Although Zhang Yu had prepared a lot of things a long time ago, he didn't often run out of the safe range of the Chashan Sect, and his survival experience in the wild was still a little insufficient, until he arrived at the fire reef and saw the salt that had crystallized, and he realized that this was a salt lake.

Zhang Yu's face was heavy, and his brows were furrowed for a while before he released his brows in a trance.

Zhang Yu untied his frowning brows not because of anything else, he thought of a way to desalinate the salt water!

Changyu took out some silt from the salt water lake and kneaded it into two mud plates, washed his hands, and burned the two plates with a blue flame ball to make two rather ugly pottery plates.

That's right, Chang Yu thought of the method of making the water purifier suggested in his previous life, and saw that the silt was very easy to burn into clay, so Zhang Yu was a little bolder, pinched a whole flat silt board, and once again drove the fireball in the Biyan Ice Front Array to prepare to burn a piece of flat glass.

Looking at the blazing blue flames, Zhang Yu pinched the spell and cast a little more heat, but he was quite complacent in his heart, he was a human being in two lives, and it was not easy for him to remember what he glanced at in a hurry thirty or forty years ago.

The salt water purifier in Changyu's memory is a flat plate tilted down, and then two plates are placed underneath, and some salt water is poured into the plate placed at the high end of the flat glass.

The sunlight shines through the flat glass to dry the salt water in this plate into water vapor, and then the water vapor re-condenses into distilled water on the flat glass, and falls into the empty plate under the influence of gravity.

Changyu's pride disappeared when the fireball was extinguished—the silt slab seemed to have been burned too much by the flames, and it became crumble.

"What's going on?"

Zhang Yu scratched his scalp for a while with some confusion, and only when his scalp was about to break did he suddenly react - the glass is made of sand!

Zhang Yu smiled bitterly and went to prepare the sand again, but there was a wry smile in his heart, he had been in this world for twenty years, and some memories had begun to be plausible!

Thinking that most people have just taken the college entrance examination for a few years, and the knowledge they have learned has been returned to the teacher, Zhang Yu has raised his vigilance in his heart:

You can't just hold it up because you're a traverser, the two worlds are different existences, Changyu is at most more mature in the three views, but the two worlds add up to only forty years, are you more mature than those Jindan Ancestors and Purple Mansion monks?

After several experiments with sand and gravel, Changyu finally made a qualified flat glass, although it was a little rough and excessive, with a lot of potholes and the same dark green as a beer bottle, but it could pass through the sun!

"Wait, I seem to remember that the dark green of the glass is because there is something in the sand and gravel that is too high. ”

Zhang Yu frowned, although the monk had a lot of advantages over mortals, it was obvious that the Qi cultivator could not forget it.

When Changyu thought for a long time and got nothing, Changyu broke the jar and was about to use it, and suddenly realized that this water purifier is not just boiling water with sunlight?

It's not that we lack that bit of fuel, why are we worried about connecting the fire veins with a lot of spiritual power as fuel?

In a blink of an eye, Zhang Yu found that he had completely complicated the simple problem, and the already low sense of accomplishment was gone.

Let's practice honestly.

When Zhang Yu pushed to the old man's shed made of bamboo, built a small shed with mud and grass and then began to cultivate, preparing to slowly replace the shed in the future, the eyes that had been staring at Zhang Yu above the fire reef finally moved to the side.

"This kid is quite honest, but he's still a bit nerdy, and he shouldn't leave his post without permission. ”

If Zhang Yu heard Zhang Qing's words, or knew that Zhang Qing was on the side, he would definitely regret it.

Zhang Yu had been struggling with the problem of how to contact Zhang Qing for a long time, if he knew that Zhang Qing was on the side, he would have told Zhang Qing about it by talking to himself, and Zhang Qing would have given a solution!

There is no regret medicine in the world, not to mention that Zhang Yu doesn't know where Zhang Qing is.

Zhang Yu's cultivation was also premeditated, Zhang Qingtang's Purple Mansion monks were afraid of the fire poison accumulated by the cultivation here, although he practiced Qi Cultivator was a fire spirit root, but there would be no water poison!

Therefore, Zhang Yu's cultivation is to take Wen Jiao out of the spirit beast bag, and part of the divine consciousness is cultivating the Panlong incarnation method in Wen Jiao's body, and the main divine consciousness is slowly cultivating in his own body.

After a week's cultivation, Zhang Yu's own cultivation is not a big problem, and the water poison is not perceived, it may be absorbed by Wen Jiao, or it may be that the predecessor has been cultivating for the dead ghost Uncle Jin and consumed a part of it.

Zhang Yu glanced at Wen Jiao lying on his shoulder again, this thing that was not the size and thickness of a little thumb was swollen at this time, no different from a silkworm baby, it was obvious that he was "eating and supporting" with Zhang Yu's synchronous cultivation, it was still possible that Uncle Jin's water spirit root was full of qi cultivation and the monk absorbed a lot of water spiritual energy!

It seems that after that, his cultivation slowed down, and Zhang Yu weighed it carefully, if it was in the outside world, the cultivation of the monk and the incarnation outside the body could be thought to be very different, but in this place where there were both auras of water and fire, Zhang Yu could only grasp it with both hands, and both hands should be hard.

Anyway, Changyu still has a whole set of array mages here to digest and absorb, the Biyan Ice Front Array still needs to be mastered, the alchemy furnace has to be erected, the shack has to be transformed, and it is not impossible to delay his own cultivation to make up for Wen Jiao's shortcomings.
