Xu Fu was stunned, and then the only bit of resentment left in his heart dissipated in an instant, and was replaced by an uncontrollable surprise.

This stubborn tiger begging for saltpeter, does it also want to refine the elixir?

If this stubborn tiger has the intention of seeking immortality, whether it is going out of the sea to seek immortal streams, or taking the self-cultivation and refining medicine stream, then they can be regarded as copying.

It's still that sentence, it's cooler than directly serving the first emperor!

If there is any need for refining immortal medicine, there is no need to spend any effort to persuade the First Emperor to ask for it, and directly let this favored stubborn tiger son definitely try everything.

"Childe wants saltpeter, but do you want to try refining immortal medicine?"

Xu Fu suppressed the excitement in his heart, and asked hesitantly.

The corners of Zhao Zihu's mouth twitched slightly, and he said in his heart: [I refine your melon skin elixir, do you really think that everyone is like you, and you are crazy and even deceive yourself? 】

However, thinking so, he didn't want to hit the self-confidence of these old gods.

After all, Li You led the fleet to the sea to find new vegetables and grains, and he had to rely on their sailing experience.

If these words wake them up and stop them from asking for medicine, they may not want to go to sea, how dangerous it is!

Therefore, Zhao Zihu not only could not hit their self-confidence, but also tried every means to strengthen their belief in seeking immortal medicine, so that it could be used by Li You's fleet.

"Hmm, I'd like to give it a try."

Zhao Zihu nodded noncommittally.

Xu Fu was even happier in his heart, and asked, "I don't know how to try it?" Tell me what to say......"

As he spoke, he raised his hand and pointed at his companions and said, "All of you are experts in this way, so you may be able to solve your son's doubts, or you can avoid some detours!" ”

Zhao Zihu resisted the urge to roll his eyes, but a bold idea floated in his heart, and after a moment of silence, he said: "I heard that there is a Shennong who tastes a hundred herbs, so there are today's grains and herbs. ”

"Although I don't know whether this is true or not, the edibility of the grains and the medicinal properties of the herbs must have been discovered by the ancient sages after tasting......"

Xu Fu and the old gods all listened to it and expressed their agreement with Zhao Zihu's statement.

Shennong tasted a hundred herbs, and single-handedly determined the five grains and many herbs, which is too mysterious.

What is certain is that it is definitely not the work of Shennong alone!

It's just that people are accustomed to worshipping heroes, so they put the credit on Shennong's head intentionally or unintentionally, or Shennong took all the credit on his own head in order to consolidate his dominance.

Of course, there is nothing wrong with this, and no one but historians will delve into it, let alone the point......

The focus is on Zhao Zihu's later words: "In my opinion, refining immortal medicine is the same, before refining, you need to find out the characteristics of various heavenly and earthly treasures." ”

"Otherwise, all kinds of heavenly materials and earth treasures will be added to the Dan furnace in one go, and they will be refined indiscriminately, I am afraid that in another ten thousand years, no one will be able to refine the immortal medicine."

"It is never advisable for an actor to know what he is doing but not know why."

"If you want to successfully refine the elixir that makes people immortal, you need to carefully understand the characteristics of various alchemy materials, and it is best to record them in a book......"

"Then, combined with the characteristics of heaven and earth, carry out reasonable compatibility refining, so that we can make progress, even if we fail, we can sum up experience......"

"Therefore, I want to start with saltpeter, soak it in fire and water, blow it in the sun and wind, and use various methods to figure out its characteristics...... Then I will ponder the next kind of heaven and earth treasure......"

Xu Fu and the old gods were stupid, and they pulled their beards one by one and fell into a stupor.

This kind of scientific alchemy method really opened their eyes, and they felt enlightened when they heard it.

One word, absolutely!

"Ahem......"

Zhao Zihu coughed lightly, waking Xu Fu and the others from their stupor.

Then, he suddenly looked serious, waved his hand and saluted solemnly: "Zihu alone, after all, he has caught his strength, I don't know if you gentlemen, are you willing to help Zihu to explore the characteristics of the world's heavenly and earthly treasures, and work together to refine the elixir that can obtain immortality?" ”

Xu Fu and the old gods looked at each other for a moment, all of them were in high spirits, and they waved their hands together and said: "Thanks to the son, I will not give up, and I will do what I want~!" ”

Zhao Zihu bowed his head and said angrily: "Good! Great goodness! In the future, there will be Mr. Lao! ”

"This matter is huge, if you gentlemen still have friends who are proficient in this way, you might as well introduce them together, and I will make offerings to them!"

When Xu Fu and the others heard this, they were even more overjoyed, and they waved their hands again and said, "We will write a letter later, and invite those who are proficient in this way to serve the son." ”

This is a good opportunity for those medicine friends to arrange for them to enter the body, and fools will miss it.

Zhao Zihu nodded with satisfaction, and then pulled back the words and said: "You gentlemen have saltpeter in your hands, prepare more for me, and I will take it back to the tent to test it slowly." ”

Xu Fu said: "We have to do this kind of experiment, so why do you need to do it yourself." ”

Zhao Zihu was more hesitant than him, and said solemnly: "If I don't participate in it myself, and I don't understand the hardships and dangers, how can I strengthen the heart of refining medicine and immortality!" ”

Xu Fu was speechless for a moment, and waved his hands in respect.

Then, from his luggage, he took out a wooden box the size of a volleyball, opened it and showed it to Zhao Zihu: "Childe, please see, the powder in this box is the refined nitrate powder extracted from saltpeter." ”

"How much does Childe need, the old man will give Childe ......"

Syllable--

Zhao Zihu didn't wait for him to finish speaking, he directly closed the wooden box and took it all out of his hand: "Give it all to me." ”

Xu Fu: "......"

This is refined nitrate, why do you want so much?

Even if you eat it as a meal, you can't eat so much in one meal, right?

"Gentlemen, get busy, I'll go back first."

Zhao Zihu ignored Xu Fu's speechlessness, and after saying goodbye, he left with Shi Shiran holding the wooden box.

Xu Fu was helpless, and shook hands with a group of old gods, until Zhao Zihu's footsteps completely disappeared, then he smiled bitterly, and muttered in a low voice: "It's really not a good man~!" ”

The old god stick standing beside him had a listener, frowned and glanced at him and said: "Brother Xu, Zihu Gongzi has such a heart to refine medicine and seek immortality, and we can be like a fish in water under his tent, we should be happy, how can we ...... How can you speak disrespectfully? ”

When the rest of the old gods heard this, they also looked at Xu Fu with disgust, as if they were dissatisfied with him slandering Zhao Zihu, the big gold lord.

Xu Fu smiled bitterly again, pursed his lips and lowered his voice: "Brothers, if you really be a stubborn tiger of the Qin people's clan, do you have any heart to refine medicine for immortality?" ”

"I don't know what he had in mind, but ...... He definitely didn't have the heart to refine medicine for immortality, and nine out of ten had another purpose, so he casually made up a set of rhetoric to fool us! ”

The old gods were stunned, and they were all speechless.

Now they all know that Zhao Zihu sent a fleet to sea, saying that it was to seek immortals and ask for medicine, but in fact, the purpose was not pure.

Zhao Zihu already has a history of deception.

Therefore, when Xu Fu said this at this time, they couldn't help but believe it.

"That'...... The method of testing the characteristics of heaven and earth treasures, summarizing them, and then using them to make them reasonably compatible with each other to refine immortal medicine, is it also fooling us? ”

An old god crouched and asked helplessly.

Xu Fu shook his head: "No, this method is very useful, we should practice it,...... One day, maybe you can use this method to refine the elixir of immortality! ”

When the old gods heard this, the haze in their hearts suddenly disappeared, and their faces were full of excitement.

What is the purpose of that rotten and stubborn tiger, they don't bother to dig into it.

They just want immortality!

As long as they can live forever, whether they are used at sea or used to refine medicines, they are willing.

Everything is immortality!

……

……

What purpose can Zhao Zihu have?

It's actually quite simple.

It's actually quite complicated.

Chemistry!

It's a good piece of knowledge!

Those old gods who are crazy and deceive themselves may not be able to do anything else, but they are definitely good at chemistry.

Isn't there a legend?

It is said that it is gunpowder, which is inadvertently made by these alchemists when they are alchemy.

All kinds of strange things were stuffed into the Dan furnace and made a big bomb......

This legend, Zhao Zihu really listened to it as a legend before.

But today, he believed!

Feel the credibility, at least more than ninety out of nine!

If you don't believe it, you can't do it.

Xu Fu, the old god stick, has brought out all the purified refined nitrate.

Isn't this a must-have for making gunpowder?

If you put some sulfur or something into the Dan furnace, and then put a fire below, it will really hell if it doesn't explode......

It would be a waste to make good use of such an awesome group of talents, mobilize their subjective initiative, and summarize the knowledge of chemistry thousands of years in advance.

A waste of brutal genius!

"I've seen Childe's ......"

When Zhao Zihu was thinking wildly, he was already walking crab steps, and when he returned to his felt tent, someone waved his hand and saluted.

Zhao Zihu retracted his thoughts, looked at the person who saluted, and saw that he was tall and fat, and obviously he was also a courtier, so he waved his hand and saluted back, and asked, "Dare to ask Mr. ”

The man waved his hands again and replied: "In Xia Zhang Cang, the official residence of the imperial history, under the edict of His Majesty, he will come to the prince's account to listen to it." ”

Zhao Zihu suddenly bowed his head, but then said strangely: "When my father gave the order last night, I was also beside me, saying that I asked Zhang Yushi to come to my account this morning to listen to it, why did he only arrive now?" ”

When Zhang Cang heard this, he had a serious posture, and he immediately broke his work, and said with a lewd smile: "I came here in the morning, but I heard that Gongzi was having something good, and Cang really couldn't bear to disturb it, so I changed to come at night." ”

This guy is also a wonderful person who is well-informed and interesting.

Zhao Zihu was happy, and said, "Good!" I heard that you are a disciple of Xun Sheng, the junior disciple of Master Han Fei and Li Xiang, is it true or false? ”

Zhang Cang waved his hand and said: "It's true that it's Master Xun's apprentice, but it's not a high-level apprentice, and it's not false that it's Mr. Han Fei and Li Xiang's junior disciple, but because of the succession of apprentices, they have never met and don't know each other." ”

But he is honest and does not cling to anything.

Zhao Zihu bowed his head and praised: "Very good! Your achievements will not be weaker than Master Han Fei and Li Xiang in the future! ”

"Go back and rest tonight, what I want you to do, you still need to cooperate with a thing, and when that thing is made, I will ask someone to find you......"

"Yui."

Zhang Cang didn't say a word, waved his hand in response, and turned to leave.

However, just after walking a few steps, he turned around and said, "I heard that Gongzi has good wine here, can you give Cang a can?" ”

Zhao Zihu, no wonder this guy is wide and fat, and he is also a foodie.

"Wait, I brought back half a jar from my father last night, and I gave it to you, it's too little."

Zhao Zihu put down the next sentence and got into the felt tent with the wooden box.

Leaning slightly, he came out with a clay pot and stuffed it to Zhang Cangdao: "This wine, for you to drink, I will treat you well, right?" ”

Zhang Cang held the wine jar with both hands, smelling the wafting fragrance of sweet wine, and couldn't help but bow his head repeatedly: "Childe is really atmospheric!" ”

Zhao Zihu said with a smile: "Don't blow rainbow farts, drink my half can of fine wine, you have to be mentally prepared, you will have your drudgery in the future." ”

Zhang Cang raised his eyebrows, and didn't ask what the drudgery was, but only asked, "Can you get the credit?" ”

Zhao Zihu nodded: "You can get the credit, the great credit, if you do it, you can at least be a master, or even a lord." ”

Zhang Cangran: "Then I am willing to die." ”

Zhao Zihu smiled: "Okay, it's best to be prepared to die like this, because I want you to go to sea with the fleet that went to sea to ask for immortal medicine." ”

The arrogance on Zhang Cang's face suddenly froze: "......"

I'm just showing my loyalty and being polite.

Can we not play this big?

Zhao Zihu saw that he was confused, but he was happy, patted him on the shoulder and said: "Male husband, fame and fortune are not fighting with your life, don't retreat from the battle...... I'm optimistic about you~! ”

After that, he ignored the constipated expression on Zhang Cang's face, turned around and went straight back to the felt tent.

Zhang Cangmu sent him to disappear into the curtain, looked down at the wine jar in his arms, and suddenly felt the sweet aroma of wine...... It doesn't smell good!

We are not the illiterate common people, we need to fight for wealth with our lives.

We are all talented and learn skills, what can't we do to earn credit, why do we have to play with our lives?

It's not worth it!

……

……

In the felt tent, the bath water is still there, but after washing, Xiang Liyue has fallen asleep on the couch.

Maybe it's because of the stuffiness in the tent, there seems to be fragrant sweat on the forehead of the mature sister Qiong.

Zhao Zihu took Xiang Liyue's bath water, and took off his armor to wash.

Then, he poured all the boxes of refined nitrate powder given by Xu Fu into the huge bathtub and slowly stirred it with a scabbard.

The refined nitrate powder gradually dissolved in the already cold bath water, and as Zhao Zihu continued to stir, it slowly seemed that a cold air was rising.

"Hmm, I didn't expect the saltpeter ice-making method circulating on the Internet to really work~!"

Zhao Zihu saw that there was an ice cube in the bath water, and couldn't help muttering.

And at this moment, Xiang Liyue's exclamation suddenly sounded behind him: "Childe, you are ...... Do you know how to do immortal arts? Can you condense the bath water into ice on a sweltering summer day?! ”

Zhao Zihu bared his teeth and turned around and said: "Yes, you have received countless blood from me today, and I am afraid that I will be able to become an immortal in time!" ”
