Fang Ce felt that the time was almost up, and some things should be done properly, so he left the palace directly.

The most troublesome thing is that the carriage that came to pick him up did not send him back!

This makes me more infuriating.

What a sin!

Running back to Jingyang from Chang'an City is simply torture, there is no money on him, is there anything to take a taxi in this era.

It's maddening that everything has to be walked.

There was no way, Fang Ce went directly to Fang Xuanling's house and found Fang Yiai, who directly got him a carriage without saying a word and sent him back to Jingyang.

However, Fang Yiai was going to go to Jingyang with Fang Ce, but was directly stopped by Fang Xuanling.

Fang Xuanling looked at his nephew, and suddenly felt a little strange.

I haven't seen this nephew for a few days.

It's like a different person.

The current Fang Ce seems to have some secrets with His Majesty, and the two of them communicate a little too much.

Even His Majesty has talked to him many times about what reward to give Fang Ce.

The key is that His Majesty didn't say anything, just said that Fang Ce's current merits can already be compared to Guogong.

How to reward you.

Fang Xuanling was confused.

It's only been a few days?

The merit is enough to be crowned a national prince?

How much of this self has he done? How old did you get to be a national prince?

What did Fang Ce do?

Later, Fang Ce moved to Jingyang, and then His Majesty sent 100,000 yuan.

You don't need to look at it to know that His Majesty has a task handed over to Fang Ce, but it's hard to say.

At this time, Fang Ce was probably carrying out His Majesty's important task, so he directly didn't let Fang Yiai go with him.

Fang Ce actually refused.

Gunpowder is still a black technology in this era, so it's better not to be known about this kind of thing.

One less person knows, one less risk.

Making a fortune in a muffled voice, this is what Fang Ce should do.

Returning to his own Jingyang territory, Fang Ce devoted himself to research at one time, and he was studying how to make the explosive power of gunpowder more powerful.

It's impossible to add tribulus terrestris to it, this thing belongs to the controlled product, you don't have iron ore, you can't make it yourself, you can't buy it.

The key is that there are only 100,000 yuan, and there is not much money!

In the end, Fang Ce thought of something.

Realgar!

Realgar is a thing that turns into arsenic when exposed to high temperatures.

Imagine that kind of scene, the gunpowder explodes, the high temperature heats the realgar, and it directly turns into arsenic, and it is everywhere, and if you are not killed, you will be poisoned.

It's beautiful to think of that kind of scene.

As for why not just use arsenic?

How can there be so much arsenic, this thing is highly poisonous, and every pharmacy must register to buy and sell arsenic.

What do you want to do to clean the arsenic of the entire Chang'an?

No one cares about this kind of thing.

After all, realgar is not a regulated product.

After thinking clearly, Fang Ce found someone to buy realgar.

Then it went straight into production, and they were responsible for packing everything to scale, and the final production part was done by Fang Ce.

After doing this for a few days, Fang Ce felt very tired and was ready to find a few people to help him.

But after thinking about it, Fang Ce gave up, these people are not safe.

After all, they are all homeless, and no one can guarantee whether their net worth is innocent.

So the plan ran aground.

However, it didn't take long for someone to visit him.

Fang Ce felt angry.

Because there is too little, it is not long before he can make such a little gunpowder, how can he kill a million Turks at that time?

The point is that people are constantly bothering themselves.

It's just unbearable.

"Under Li Chunfeng, come to visit Fang Jushi."

Fang Ce doesn't want to see it.

This guy is actually Li Chunfeng, who was originally a Taoist.

But he is a special official, which is very troublesome.

When you meet such a guy, if you don't see him, you won't give him face, and you will wear small shoes for yourself in the future, what should you do?

After all, people are Taoist priests, and I would like to say to Li Shimin, Fang Ce is the disaster star of the Tang Dynasty in my opinion.

After finishing the calf, Li Shimin will definitely kill himself quickly.

There's not much self-protection right now, so don't go too far.

"Daoist Li, what's the matter with me?"

Fang Ce tidied up his clothes, he hadn't taken a shower for several days, and when he was sleepy when he made gunpowder every day, he lay down, and then woke up and continued to make.

It's too much of a stretch to do the same thing over and over again.

"Fang Jushi is alchemy?"

Li Chunfeng's nose was sharp, and he felt that Fang Ce's body seemed to have the smell of pills.

"Well, you're right, I'm practicing an elixir that can make people soar in the day, and all diseases will be eliminated."

Fang Ce continued to talk, and he didn't brag, the bomb was put under his feet and ignited, will it soar in the daytime?

Dead people, are they not sick?

There's nothing wrong with that.

"This ......"

Li Chunfeng originally came to discuss the math problem with Fang Ce.

I didn't expect Fang Ce to actually do alchemy.

This was a big surprise to him.

He Li Chunfeng is a Taoist priest and a big man in the arithmetic world, and he will also go to Guozijian from time to time to teach.

Today, he is the second in arithmetic, and no one dares to call him first.

It's such a terrible existence, I have to be a Taoist priest.

You say it's funny or not, the key is that you are still famous as a Taoist.

is like Li Bai, who was originally a dashing ranger, the second in the world in swordsmanship, but he didn't write poems properly, and then won the title of poet immortal, completely overshadowing his name as a sword immortal.

If Li Chunfeng had concentrated on arithmetic, he would probably have been a famous mathematician.

"Immortality?"

Li Chunfeng was obviously more interested in pills than in arithmetic.

"Immortality is not immortal, but immortality can be immortal."

Immortality doesn't exist, don't you get old, when will you die, won't your face be forever? Will it still be old?

"Then let's study it well in the future, and when the time comes, I will call Sun Daoyou and Yuan Daoyou over to study it together, maybe there will be some breakthroughs?"

Li Chunfeng was very interested in alchemy, and pulled Fang Ce eager to bring him into Taoism.

Fang Ce was also speechless, Yuan Tiangang, this is the number one god stick in the Tang Dynasty, Sun Simiao, this is the King of Medicine.

Why do you say that Li Chunfeng, a great astronomer, mathematician, and Sun Simiao, a great medical scientist, are mixed up with this great god surnamed Yuan?

Although Yuan Tiangang also studied astronomy, he studied it for and deception, and in the end, his fame was on par with Li Chunfeng and Sun Simiao.

For atheists, Yuan Tiangang is a liar and a god, but in the eyes of people in this era, Yuan Tiangang is a god.

However, Fang Ce didn't believe this, so he felt the need to pull Li Chunfeng on the right track.
