Royal road

Ge Hong is not the kind of reckless person.On the contrary, he is delicate and patient.After getting the elixir given by Liang Feng, he did not burn the elixir directly according to the doses of one catty of saltpeter, two ounces of sulfur, and three ounces of charcoal, but adopted the halving method to test the effect a little bit.

After a few times, Ge Hong concluded that this recipe can indeed help fuel the fire.As long as it sees fire, it can burn quickly, emitting sparks and white smoke.However, when he put the potion into the alchemy furnace, something unexpected happened.After a loud noise, the alchemy furnace in front of him was exploded, but fortunately, the dose of medicine was not large, and no one else was hurt.

Ge Hong didn't forget that after Mr. Liang gave him the pill, he specifically told him that it was dangerous.This could not be more true.Even the alchemy furnace can be blown up, so is it not dangerous?For alchemists, this is a life-threatening prescription, who would use such a ratio to put the pill on fire?

Facing Ge Hong's questioning, Liang Feng sneered: "This party came from the fire, but Zhichuan is not curious, why does a little medicine lead to the explosion?"

Ge Hong was taken aback for a moment, yes, it was not a one-time experiment for him to experiment with this potion.Why is it usually ignited, but some sparks come out.Put it in the alchemy furnace, but it will make such a big copper furnace crack and smoke, making a loud noise?

Is it because of the different conditions when the medicine meets the fire, or is there some other reason?

Regardless of the people around him, Ge Hong hurried back to the alchemy room.He dug out several doses of potions, and after simply mixing them, he poured them into the medicine bowl, lit a piece of waste paper, and threw it in.

"My lord, be careful!" The smoke in the alchemy furnace hadn't dissipated completely, so Yiyan dared to be careless, and immediately stood in front of Liang Feng.

"It doesn't matter." Liang Feng pressed Yiyan's shoulder so that he needn't be nervous.The flames swished and ignited the black potion in the bowl, a spark was ignited, and then it was completely extinguished like a gust of wind.

Ge Hong looked at the medicine bowl in front of him and frowned.After thinking for a while, he poured in the same amount of medicine as before, got up and found the lid of the medicine bowl, covered the medicine bowl, and used a piece of twine as a guide.

This time Liang Feng reminded: "Zhichuan be careful."

Hearing this, Ge Hong became more determined in his heart, and after lighting the hemp rope, he took two steps back.The twine burned quickly, and the outer thread was burnt clean in a short time. After a while, there was only a crisp sound of "pop" in the bowl, just like the sound of firecrackers exploding.The lid of the medicine bowl was lifted a little, and the smell of saltpeter came out.

"The frying furnace is not because of the medicine, but because of the pill furnace!" Seeing this situation, Ge Hong couldn't guess the reason.No matter how the medicine is burned normally, there will only be some sparks, but once the furnace cover is closed, it will immediately cause a loud noise.The problem obviously lies in the container of Dan Furnace.

Seeing Ge Hong's quick reaction, Liang Feng also smiled slightly: "Zhichuan's expectation is right, it is because of the alchemy furnace. The air is hot and cold, cold and shrink, hot and expand, if there is a sudden change, it will generate energy This power has nowhere to vent, and it will explode the blocking object, so the fryer will be triggered."

This statement is unprecedented.However, Ge Hong is a person who loves to observe, and after thinking about it for a while, he realized that what Liang Feng said was true.Just like boiling water in a large pot, when the water boils, there will be air to lift the lid of the pot.It's just that the water is boiled slowly and the medicine is drawn very quickly, so the different changes have just occurred.

"In this way, this recipe can indeed be used in a fire, but it cannot be used in a furnace!" After discovering a new theory, Ge Hong couldn't help but feel a little happy.

You must know that frying furnaces appear in alchemy, which is not uncommon.But most alchemists would only think that there was something wrong with their operation, or that the alchemy they made was taboo by the heavens.No one had ever thought that it was the reaction caused by the medicine.Both saltpeter and sulfur are commonly used alchemy materials, and charcoal fire is inseparable from the furnace.If these things can be prevented from being mixed together, the probability of frying the furnace will be much smaller.This is a pleasant surprise!

"Its use is not limited to alchemy." Liang Feng's face became serious, pointing to the pill furnace that was blown open, "such a pill furnace can be exploded by this medicine. If it is replaced with a larger dose of medicine Yin, can you also crack mountains and rocks, and attack cities and villages?"

Ge Hong was startled.Cracking mountains and cracking rocks, attacking cities and pulling out strongholds, can it be done with only the medicine in the furnace?However, he came from a alchemy master like Zheng Yin, and he has heard a lot of alchemy anecdotes.It is true that once there was an alchemist whose house collapsed because of the furnace explosion, and there was no bones left.How much medicine can be stored in the pill furnace?If it is multiplied a hundred times, maybe it can really do what the Liang Fujun said.

But this has nothing to do with the Golden Core Avenue he wants.

After a moment of silence, Ge Hong finally said: "Golden Core Dao is only for ascending immortals, and it should be medicine for healing people, not what the Fujun said."

Whether it is to open mountains or pull out villages, they are far from his pursuit.What he wants to do most is to save the world, to accumulate goodness and virtue, and to find the true path to immortality.

Liang Feng shook his head lightly: "There is more than one road? Just like this recipe, it can prevent casualties in the pill furnace, but it can save countless absenteeism and hard work when placed in the mountains. If you encounter a strong city and cannot overcome it, It can live countless lives. But no matter where it is used, the cause of the furnace explosion has never changed. It is like the sun rising and the moon setting, and the stars moving. So, why not Tao? To know'. To study these worldly laws is the only way to find the Dao."

The phrase "extending knowledge lies in investigating things, and then knowing things" comes from "Book of Rites·University", but Zheng Xuan interpreted it as "knowledge in the depth of the good will bring good things, and know in the depth of evil will come to evil things." .Ge Hong actually does not agree with this statement. It is obvious that cause and effect are reversed, which is contrary to the meaning of the text.However, he was poor since he was a child, and he has never worshiped a famous teacher. Although he felt wrong, he couldn't refute it.

And when Liang Feng interpreted "gewu" as studying the laws of the world, it was the only way to reach true knowledge.Ge Hong felt a little enlightened.What he loves most in life is observation.Without this meticulousness, how can we find out the source of various diseases and the pharmacology of the golden elixir?

It's just that what he pays attention to has always been the effect that the golden elixir can bring, not why these mineral medicinal materials change and merge into one.It's like seeing a leopard in a tube, or a blind man touching an elephant. He is complacent when he only has a corner, and mistakenly thinks that he has glimpsed the true knowledge of the world.Isn't this a sign of being obsessed with skills and neglecting the way?If you want the method of golden core to become a real Dao, I'm afraid it's not enough to only scratch the surface.

"But this way, can it save people's lives?" Ge Hong couldn't help asking the most critical question.

Hearing what Ge Hong said, Liang Feng was not discouraged, but felt a sense of emotion.If he didn't have this kind of heart to save the world, how could Ge Hong leave two works handed down from generation to generation?

"If there is a medicine that can kill insects without harming the seedlings, tens of thousands of acres of fertile land can be free from pests. If there is a medicine that can penetrate into gold and iron and make it indestructible, countless soldiers can live because of it. The reason why the road is a road is precisely Because of its broadness and comprehensiveness, as long as you have a short way, why worry about not being able to save the world?"

Chemistry is an important science related to people's livelihood.If we can start now, we will break away from the primitive and ignorant religious beliefs and enter a benign development path like mathematics and medicine.The changes brought to this world will also be amazing.

Hearing the person in front of him speak so solemnly, Ge Hong's heart was moved after all.If he was a few years younger, he might still be obsessed with his official career, and he only wanted to be an official and shine on his family.If he was a few years older, he might be hurt by the troubled times, completely abandon the mundane, and devote himself to the way of immortality.

But it just so happened that he met Liang Feng at this time.Hearing these heart-warming words.He still has ideals, pursuits, and a heart of helping the world that does not want to be extinguished.

Sighing lightly, Ge Hong said: "Fu Jun is really not like a member of the Shi family."

What Buddhism seeks is never the present world, but the afterlife, salvation, and liberation.Therefore, as a Taoist believer, Ge Hong has never put Buddhist believers in his eyes.In his opinion, these are all chaotic people who betray the principles of the world and are not worthy of close friendship.However, the Liang Fujun in front of him was really beyond his expectation.

Although he has the name of a Buddha, but this person's various actions have never retreated in the slightest, but are full of vitality.This is the case for his own details, his unscrupulous guidance, and the Chongwen Museum opened by Fuzhong, which is not like those pedantic and decadent children of aristocratic families.

How could such a person believe in Buddhism?

For the people of the world, what to believe in is a question worthy of entanglement.But for Liang Feng, he never had such worries.

"Whether Buddha, Zhongni, or Lao Tzu, they are all born and grown in the world. Even if they are bestowed by heaven, what they see is nothing but the things of this world. Only the eyes are far and near, and the views are different. Dao produces all things, and nature exists in various forms. What the sages saw is like walking in the Tao, which seems to be different, but in fact they lead to the same destination." Liang Feng smiled slightly, "I am not a sage, so I dare not criticize the way of the sages. Only by listening, can you be wise."

This idea is really shocking.But Ge Hong could not find a way to refute.Why isn't he using the Confucianism he learned to explain the ultimate principles of Taoism.If there are really thousands of paths leading directly to the truth in this world, why should he care what the person in front of him believes in?

Seeing that Ge Hong's expression was shaken, Liang Feng made a decisive decision and bowed: "Please also ask Zhichuan to stay in Lucheng and help me find the root of this great way."

This is not helping him, it is clearly helping himself to gain the Tao.Ge Hong only felt his heart beating, and finally pulled back his sleeves, and bowed in the same way: "Your Majesty Meng will not give up, Hong is willing to do his best!"

Liang Feng let out a long breath: "I never thought of a pill recipe, but it's really my luck to be able to replace it with a good material! But alchemy in the mansion will eventually be inconvenient. Why don't we build another temple in the west of the city for Zhichuan Qingxiu."

"Mr. Laofu is bothering you. It's just that alchemy is cumbersome, and I'm afraid several Taoist boys are needed." Ge Hong thought for a while, and said simply.

"This is easy to handle. I will find some talented children to work in the temple. But the gunpowder side has a very important issue and needs to be kept secret." Liang Feng warned again.

"Gunpowder?" Originally born from the fire, and ignited by the flame, it is quite appropriate to change the name to gunpowder.After chewing on the word, Ge Hong nodded, "Don't worry, Fujun, I know this myself."

Ge Hong also personally participated in the battle, so he naturally knows the significance of sharp weapons for warfare.If this gunpowder is used well, I'm afraid it can turn things around.

"That's good!" Finally reassured, Liang Feng smiled and asked Ge Hong to wash up.On the side, Yiyan frowned, looking at the dark, cracked alchemy furnace.Is what this Taoist practiced really that powerful?

Suppressing the doubts in his heart, Yiyan turned his gaze back, followed Liang Feng closely, and walked to the front yard together.
