In fact, alchemy has also provided a lot of help for the historical process of China, such as gunpowder, one of the four major inventions, is the product of alchemists, of course, alchemists have also produced a lot of chemicals, such as Ge Hong, although this person is dedicated to alchemy, and he also wrote a book, but he also recorded a lot of knowledge about chemistry, such as the earliest reversible reaction of mercury sulfide, which was recorded by Ge Hong.

But I always eat this kind of stuff that contains heavy metals that exceed the standard, and I am afraid that it is enough to cultivate immortals, but if I want to become an immortal as soon as possible, it is inevitable.

And Lu Chen also remembered that Li Shimin later took this so-called "elixir", and Li Shimin only lived to be fifty-two years old, is it also related to this "elixir"? Of course, this is only a record that Lu Chen has seen in the history books, as for whether it has anything to do with this, Lu Chen can only guess.

However, eating this kind of heavy metal stuff is definitely chronic suicide, which Lu Chen can be sure of, but fortunately, no one has taken this thing now, whether it is Li Yuan or Li Shimin, or even Li Jiancheng, who is sick, no one has taken this thing, which makes Lu Chen feel at ease after all.

It's just that the old immortal in front of him actually opened the road of alchemy, which made Lu Chen a little uncomfortable, and this old immortal lived to be more than one hundred and forty years old before he died, as soon as he met, he directly said in front of others, "There is a problem with your elixir", after all, some people are too faceless, but fortunately, today can be regarded as knowing this old fairy, if you can keep this old fairy and let this old fairy's attention return to medical skills, can you make Sun Simiao no longer worry about alchemy?

"Lu Xiangong, but is there anything wrong with Poor Dao coming this time?" Seeing that Lu Chen finished speaking, he didn't say anything again, as if he was contemplative, Sun Simiao asked in a tentative tone, after all, he could be regarded as uninvited this time, if he disturbed Lu Chen because of this, Sun Simiao would inevitably feel guilty in his heart.

"Huh?" Hearing Sun Simiao shouting himself, Lu Chen hurriedly raised his head, Lu Chen didn't expect that he was so contemplative, and he actually made Sun Simiao misunderstand something, and hurriedly smiled apologetically: "No!" How could it be! Being able to see the old fairy Tianyan, I just feel fortunate to have three lives, but I just suddenly remembered some things just now! I'm sorry that the old fairy misunderstood! ”

"Oh!" Hearing Lu Chen say this, Sun Simiao was relieved, "I wonder if it is convenient to ask Lu County Gong to teach some medical things at this moment?" The eyes in Sun Simiao's eyes were full of thirst for knowledge, "In addition, Lu County Gong can no longer call Poor Dao 'old immortals', compared to Lu Xianhou, what kind of immortal is Poor Dao?" Speaking of this, Sun Simiao looked at Lu Chen with burning eyes.

Hearing Sun Simiao's words, Lu Chen's heart was "groaning", could it be that this medicine king saw something? It is said that people outside the square have some special abilities, what Qimen Dunjia, the number of five elements, does this medicine king also understand these? Lu Chen couldn't help but glance at Sun Simiao suspiciously, "Why did the old Taoist say this?" ”

"Bai Yujing in the sky, five cities on the twelfth floor..."Seeing Lu Chen's suspicious gaze, Sun Simiao stroked his beard that shimmered with silver-white light, and looked at Lu Chen with a smile and chanted.

"How did the old Taoist know about this poem?" Hearing Sun Simiao's words, Lu Chen was shocked again, you must know that when Lu Chen recited this poem, there were not many people who knew and heard it, and this definitely did not include Sun Simiao who was sitting in front of Lu Chen.

"Although Lao Dao is old, he is neither dazzling nor deaf!" Sun Simiao still looked smiling, and said indifferently.

Hearing Sun Simiao's words, Lu Chen immediately understood, they all said that this old fairy is a crane-like figure like an idle cloud and a wild crane, wandering all over the world, hanging pots to help the world, but in fact, this old fairy is very well-informed, after all, he has lived for such a long time, if he has no ability, in this era of war and chaos, it is really enough, Lu Chen nodded, as for how he found out, Lu Chen will not ask, because even if he asks, Sun Simiao may not be able to say, it is better not to ask.

Seeing that Lu Chen was just surprised, he regained his calm expression, Sun Simiao was also a little surprised in his heart, Sun Simiao said this in fact, he also wanted to get some useful news from Lu Chen, and even said that he wanted to know the whole of Lu Chen's poem, if possible, Sun Simiao even wanted to ask for a pill or something in Lu Chen's place, after all, why did Sun Simiao live in seclusion in Zhongnan Mountain for alchemy, and didn't he want to ask for an immortality?

However, since he saw that Lu Chen was not interested in talking about this matter, Sun Simiao did not ask anymore, because he felt that if he continued to ask and made Lu Chen unhappy, then the gain would outweigh the loss this time, so Sun Simiao tacitly did not say anything about this matter.

"Have you ever eaten?" Lu Chen directly changed the topic and mentioned dinner, after all, Sun Simiao's arrival interrupted Lu Chen's meal plan, and the two wild deer were still lying on the ground in the front yard.

"No!" Sun Simiao replied very simply.

"In that case, it's better to meet by chance, I don't know if it's okay to invite the old Taoist to dine together?" Lu Chen sent an invitation to Sun Simiao.

"Since Lu County is invited, how can there be any reason not to obey? What's more, Poor Dao heard that Lu County Gong is also quite proficient in cooking, and today he is going to ask for a meal from the county lord! Sun Simiao stroked his beard and said with a smile.

"This old Taoist priest knows a lot!" Looking at Sun Simiao's smiling appearance with his beard brushed, Lu Chen couldn't help but slander in his heart, but Lu Chen couldn't say this, after all, if you want to save Li Jiancheng, this old Taoist priest is indispensable, and those medical books in the base are estimated to be more useful to this old Taoist priest than to Lu Chen, not to mention that Lu Chen doesn't feel that he is a genius, he can learn everything, Lu Chen also tried to learn it at night when he was fine, it turns out that Lu Chen is really not that material, As for the medical knowledge learned in the special combat team, it was all memorized by rote, and Lu Chen only knew some medical knowledge at most.

"In that case, then ask the old Taoist to move to the front yard! After all, if this venison is delayed for a long time, it will not taste good! Lu Chen got up and made a "please" gesture at Sun Simiao.

"Then the poor way is as it suits the Lord!" Sun Simiao got up and followed Lu Chen to the front yard again, at this time the two wild deer were still lying on the ground, but the arrow clusters on their bodies had been cleaned up.

"This deer antler velvet is a good thing!" Sun Simiao stood beside Lu Chen, looked at the eight-pronged antler on the head of the wild deer, and said in a low voice, "It's rare to see such a huge antler!" ”

"As far as I know, this wild deer is full of treasures!" Lu Chen pointed to the middle and back parts of the wild deer's abdomen, and said meaningfully, "Don't damage this deer skin for my father, my father will be of great use!" Looking at the skins of these two wild deer, Lu Chen suddenly came up with the idea of making a sofa, because of environmental protection and animal protection in later generations, there are very few sofas with this kind of wild animal skin, and now there is an opportunity to make a sofa with pure wild deer skin, Lu Chen said that he has to try anything.

"It's a pity that they are all male deer, and there are no doe, otherwise we can see if there is a deer fetus!" Sun Simiao looked at the two male deer lying on the ground, and couldn't help but say with some regret.

"This kind of thing is hard to find, if you force it, it is really hurtful!" Hearing Sun Simiao mention the deer fetus, Lu Chen remembered how the deer fetus was obtained, which was in the spring, so that the doe was conceived, and when the doe was pregnant for three to four months, the fawn was formed in the mother's body, killing the doe, and directly taking out the doe's body together with the uterus, and then soaking, molding, baking, and drying in wine to obtain the deer fetus.

In Lu Chen's opinion, this method is more cruel than creating a fistula for a black bear and obtaining bile, and Lu Chen is not in favor of obtaining a deer fetus in this way, so after hearing Sun Simiao's regretful tone, Lu Chen couldn't help but say a word.

"Lu Xiangong really has a compassionate heart!" Hearing Lu Chen's words, Sun Simiao praised Lu Chen on the side.

"Compassion?" Lu Chen directly glanced at Sun Simiao strangely, "Maybe, but has the Taoist ever heard a word?" Lu Chen looked at Sun Simiao and asked.

"What?" Sun Simiao asked curiously.

"Snakes and scorpions should be reciprocated, and the mercy of the Daomen will also punish the evil?" Lu Chen suddenly remembered a sentence from Master Tan Zong of Jueyuan in "Shaolin Temple", of course, the original words were "Snakes and scorpions should be returned, and my Buddha is merciful and punishes evil", but Lu Chen has never been very interested in Buddhism, so he directly changed this sentence here.

Hearing Lu Chen's words, Sun Simiao's eyes lit up, "Lu County's words are very good!" Sun Simiao praised Lu Chen again.

"Dao Chief, I don't know much about the Dao Sect below, I don't know if the Dao Leader has any taboos?" Lu Chen looked at Sun Simiao and asked, after all, he knew that Sun Simiao was a person in Taoism, and Taoism was divided into the Zhengyi faction and the Quanzhen faction, but the Quanzhen faction was founded by Wang Chongyang hundreds of years ago, and history said that Sun Simiao was from the Qingcheng faction, and Qingcheng belonged to the Quanzhen faction, but I don't know if the Quanzhen faction at this time was also the same as later generations, unmarried and vegetarian, so Lu Chen asked this question.

"There are no taboos in the poor road!" Sun Simiao replied with a smile, Sun Simiao was still quite moved by Lu Chen's concern about his diet, and said that he was a famous doctor and famous, but if he really wanted to compare with Lu Chen, he was a white cloth, and Lu Chen really had a knighthood, for Lu Chen to be able to care so much about Sun Simiao, in Sun Simiao's opinion, Lu Chen is a corporal of Lixian, and he is condescending.

"So good! I'm afraid that if the old Taoist eats fasting, there will be no good luck! This venison is a good thing! Lu Chen looked at Sun Simiao with a smile and said.
