After seven years of fiefdom, Li Shimin asked me to return and become the crown prince.

Outside the Prince of Chu's Palace.

A middle-aged Taoist priest in a green robe stood there, looking a little solemn, with a very conflicted expression on his face.

He was the Taoist priest Changyuan of Qingxin Temple.

Their Taoist temple relied on selling fireworks to attract pilgrims, but the fireworks feast that Li Kuan released on New Year's Eve completely reduced their Taoist temple to a spark of embellishment in the fireworks.

In the past, they would give some fireworks as gifts to pilgrims who came to burn incense, and they also attracted many wealthy pilgrims to the Taoist temple through this.

They rely on these pilgrims to support the people in the Taoist temple, but this time, since the New Year, fewer people have gone to their Taoist temple to burn incense.

If it continues like this, the Taoist temple may go bankrupt.

They are competing with several surrounding Buddhist temples, and their incense seems to be on the verge of surpassing their Qingxin Temple. Changyuan is a little curious why the people now like those bald donkeys.

What's so good about some bald donkeys who can only chant scriptures ?

"" Master, please come in!" Zhao Xin came out of the mansion at this time and invited him in.

Entering the banquet hall of the Prince of Chu's mansion, he saw the handsome young man sitting in the main seat with extraordinary demeanor. He hurriedly stepped forward to greet him:"I, Changyuan, greet His Majesty the Prince of Chu!"

Standard Taoist etiquette, this gesture Li Kuan had seen in Li Chunfeng before.

Li Kuan nodded and motioned for the Taoist to sit down.

Liu Xin served tea.

After the Taoist Changyuan drank a sip of tea, Li Kuan asked:"I wonder what your purpose is in looking for me?"

Li Kuan was also a little curious. It seemed that he had no dealings with the Taoist priests of Qingxin Temple.

"Your Highness, I am sorry for being so presumptuous. I just want to ask where the fireworks that Your Highness set off on New Year's Eve came from!" The old Taoist Changyuan did not beat around the bush and directly stated his purpose.

In fact, during this period, except for those sour scholars who liked to beat around the bush, everyone else spoke more directly.

The folk customs were also more simple.

"Fireworks? Of course they were made by the Prince of Chu’s Mansion. Otherwise, do you think others would give them to me? I am not very popular in Chang’an City!" Li Kuan joked to himself. When

Taoist Changyuan heard this, he looked at Li Kuan in surprise and said,"The Prince of Chu also knows how to make elixirs?"

""Alchemy? What does the Taoist priest mean by that?" Li Kuan smiled and shook his head.

"To be honest with you, Your Highness, these fireworks and the deafening sound were all achieved by my master in alchemy. Later, after we improved them, they became the current fireworks. I thought these fireworks were unique to my Taoist temple, but it seems that we are complacent!"

Master Changyuan smiled bitterly and shook his head.

Improvement?

Li Kuan looked at Master Changkong, and his eyes flashed with some different brilliance.

People like Gongshu Ziyu of Lingnan are already stretched to the limit in studying some mechanical things, and occasionally they have to mix some pharmaceutical chemistry things, which makes the people in Lingnan Military Workshop a little too busy.

Now most of the chemical things are made by Li Kuan directly drawing up the formula.

It is almost impossible for people in the military workshop to conduct their own research in chemistry to break through new areas because the research directions are different.

I have to find some talents in chemistry and let Gongshu Ziyu and others focus all their attention on machinery.

Of course, aren't these Taoists who focus on alchemy the best talents? They have read books and like to tinker around. It's best to let them tinker with chemical things.

""Your Majesty, could you let me see the fireworks?" The old Taoist said hesitantly when he saw Li Kuan staring at him.

But he also knew that it was inappropriate to say this so presumptuously.

The recipe of the fireworks belonged to the King of Chu himself. If it were him, he might show it to others.

This would be the foundation of his Taoist temple.

"No, this fireworks formula is confidential for the time being, I can't let you know!"Li Kuan shook his head decisively. The gunpowder formula really couldn't be shown to these people.

Besides, Monk Changyuan was studying gunpowder. If he took one back, he would probably be able to copy one that was almost the same the next day.

The gunpowder formula couldn't be leaked yet.

"This is it!"Chang Yuan was a little disappointed, but he could only sigh and shake his head. It was his honor to have the King of Chu show him. If he didn't show him, there was nothing he could do. It seemed that he should go back and study his fireworks carefully to see if he could improve them.

"Taoist Priest Changyuan, I wonder how many fellow Taoists are there who are studying alchemy with you?" Although Li Kuan noticed Changyuan's disappointment, he asked again.

Huh?

Changyuan was stunned by Li Kuan's question, but still answered:"My three brothers and I are good at alchemy, and the disciples below also know a thing or two! There are probably about forty or fifty people!"

Taoists have self-cultivation and mind-cultivation. Their Qingxin Guan is about alchemy.

Li Kuan's eyes became brighter and brighter as he listened to Changyuan's introduction. (To read exciting novels, go to Feilu Novel Network!)

Isn't this just digging out the nest?

Bringing all these guys to Lingnan for training is definitely the basis for laying the foundation of chemistry. If he gives guidance in the right direction, there may be breakthroughs.

Taoist Changyuan looked at Li Kuan's fiery eyes and felt a little cold. His Royal Highness the King of Chu would not have any bad hobbies, right? I heard that the current Crown Prince has some eccentric hobbies.

The King of Chu would not be the same, would he? He is almost forty years old.

While he was daydreaming, Li Kuan coughed twice and continued to pretend to be knowledgeable and profound;"Taoist Changyuan, although I can't let you see the fireworks, I still have some new things here. I wonder if you are interested!"

"What is it?" Taoist Changyuan was curious and blurted out the question.

"Something that can make you understand the world more clearly, and maybe it will help you refine other things!"Li Kuan did not refine the pill, but continued to add ambiguously:"Now we have refined a liquid medicine that can treat fever, whooping cough and other symptoms!" What Li Kuan said was not wrong, allicin was also refined, and it was not wrong to say that it was a liquid medicine.

When he sees the microscope, I think he will be attracted by the effect of the microscope and will not think too much.

"Where is it?"Chang Yuan Daoist was a little excited. He collected rare treasures from all over the world in order to refine high-quality elixirs. Now he finally had hope.

Moreover, he had heard that recently the Chu King's Medical Clinic had a liquid medicine that could treat fever, pneumonia and other symptoms.

Could it be a new elixir formula developed by the King of Chu?

In this way, he was even more looking forward to the place Li Kuan mentioned.

"

Taoist priest , follow me!" Li Kuan did not waste any time and took Chang Yuan straight to the Chuwang Medical Clinic. Đạo Vô Tâm
