Liu Chan had been observing these two elders who were quite immortal and chivalrous, which made him think of the Taoist who lived in the mountains and occasionally entered the world. Pen, fun, and www.biquge.info

And the other party's conversation convinced him of this even more, especially the old butler's squinted eyes, which made him realize that these two old men were definitely not idle people.

Qingcheng Mountain!

That's right, it's called Tiancang Mountain now!

Such a place name suddenly popped up in his mind, and this place name is also an important reason why he chose Wuyang City, others don't know the value of the Taoist who built the mountain in the mountain, but if he doesn't know the modern memory of the owner, it is really a vain life in the previous life.

"I don't know the two Taoist masters, but what is the matter with looking for a boy?"

Liu Chan's voice was not loud, just enough to make Qingyun Qingsong in front of him listen to it.

Qingyun was stunned for a moment, and in a blink of an eye, he understood the meaning conveyed by the other party's words, and he didn't know what to do for a while. However, Qingsong Daoren was in charge, and immediately stood up and bowed.

"I don't know that the young master of Zen is here, but the poor Dao and the junior brother are offended."

"It doesn't matter." Liu Chan also returned the salute, "The Taoist chief sat down, just now the kid heard that the two of you seem to be talking about the flood?" ”

Hearing Liu Chan's question, Qingsong Daoren glanced at Qingyun who hurriedly stood up and then sat down in a hurry, and sighed in his heart that his junior brother was still like a child's heart at such an age, but he couldn't help but look at the old man behind Liu Chan who had the same face as his junior brother, but there was a faint sense of sharpness, and his heart was firm about Liu Chan's identity.

With such a world-class master to protect him, he must not be so idle and bored to pretend to be someone else.

Qingsong Daoren nodded and sat down. As the head teacher, he thinks much more than sitting opposite, looking down at his nose and nose, looking at his heart, and always relying on his junior and younger brother to think about everything as in the past. Although he didn't want to enter the WTO, he didn't want to offend the people in power without a head, after all, before that, the master who was beaten by Cao Cao and moved his family to Yecheng is the best example.

"Since the young master of Zen asked, then the poor way will not say those mysterious and mysterious empty theories." Qingsong smiled lightly, "Originally, Xiaodao saw that the people near Wuyang had no way to avoid floods, and thought that most of them didn't know that the flood was coming, so they came to this city and wanted to report to the government, but I didn't expect that it was the young master who had already seen the opportunity and responded, but Xiaodao almost made a joke." ”

Liu Chan couldn't help laughing, he didn't expect that this Taoist with a childish face and two sideburns was quite good at communicating with people, he thought that Taoist people were all difficult to deal with, but now it seems that most of them were harmed by those film and television dramas in later generations.

But this is not certain, after all, Taoism has just started now, and it has not yet departed from the shadow of pre-Qin Taoism, and the hundred schools of pre-Qin princes are precisely serving the king, and there is no such thing as the Tao in later generations, regardless of the world.

"Young Master Zen, Xiao Dao still has some doubts in his heart, I wonder if the young master can answer it?" At this time, Qingsong Daoren asked again.

Liu Chan's face was straight, "It's okay to ask." ”

Qing Song thought for a moment and said, "The thing that built the embankment, that is, cement, really has such a miraculous effect? ”

It is normal for Qingsong to have doubts, since he cultivates the Tao, then alchemy and refining talismans is a compulsory course, while refining, he naturally understands a lot of natural principles, for such things that are somewhat contrary to the way of nature, Qingsong is indeed true If he can't see it, he will always be difficult to believe.

The other party's words happened to be in line with Liu Chan's intentions, and he was worried that he didn't know how to send an invitation to these two.

And after entering his mansion and seeing those things, he believed that there was no cultivator in the world who would not be moved!

He just wants this one to be excited! Because for Liu Chan, these Taoists are concerned about the direction of the war in the south, in fact, even if they don't meet these two people today, these **** will go to Tiancang Mountain to visit! After all, according to the time calculation, the construction of the Great Wall with the support of cement will not take long, so the matching other facilities will be taken out at the same time when it is completed, and no matter how bad it is, there must be corresponding technology!

……

At this time, in a large room named "Basic Chemistry" in the Shu Academy of Sciences, there were several tables with many glass products on them.

In one corner, more glasswork was discarded, and although it was dazzling in the light that sometimes burst out, it could not hide the fact that they were abandoned.

Everyone knows that what is placed on the table is the finished product.

Ma Husi and a group of Mo family disciples were wearing white lab coats and meticulously inspecting the finished glass experimental tools on the table, picking out the defective products hidden in them, and then throwing them out.

The experimental clothes on his body were completely different from the clothes of this era, and at this time Liu Chan sewed them according to the work clothes of later generations, and they were not used to it at first, but later found that wearing such clothes was indeed more safe and reliable.

"All test tube catheters must be inspected and measured, and errors of more than 0.1 millimeter are defective, you know?"

Ma Huhei's stern voice sounded in the room, but he also knew that it was too difficult to identify the error of 0.1 millimeter, after all, the minimum scale of the scale in the laboratory was only millimeters, and no matter how small the unit was, the young master Liu Chan's answer was "It can't be accurately engraved with the existing technology, and the reluctant marking is just a deception."

It's no wonder that Liu Chan, after all, there is no laser at this time, and it is impossible to determine the scale with the help of its wavelength, and even the current scale measuring instruments are divided according to the existing units. But it doesn't matter, as long as the unit of measurement is unified with the scale standard, as long as there is no joke that one millimeter on one side and one meter on that side, and the same length on both sides.

On another laboratory table in the room, there is already a complete set of glass distillation equipment that has been assembled.

Others have been moved to another room in the same "Basic Chemistry Zone," where several Mojia people who have learned the method from him are preparing sulfuric acid. The temperature over there is much higher than here, after all, refining glass only requires part of the process to control the temperature, while refining sulfuric acid requires a boiling furnace to oxidize the sulfur in pyrite into sulfur dioxide gas. Of course, all this knowledge was learned from the basic chemistry course taught by the young master.

As soon as he thought of this, Ma Huhei's face twitched a little, you must know that after each class, the young master will leave some "after-school homework", and he still has a long list of chemical reaction equations that he has not memorized......

"You go ahead, I'll go over there and have a look." For that side, Ma Husi was still a little uneasy, and after checking the few things on his hand, he greeted and walked towards the sulfuric acid refining room.

But as soon as he went out, he saw the figure of the young master walking over to this side, followed by two old men with gray hair and fairy bones.

"Taoist!" Ma Huji immediately understood the identity of the other party.

After all, he used to be a wandering magician, and he was also a man of the Tao......
