Zhao Ding didn't know what was happening in the capital.

But what Zhao Ding knows is that he has been free recently.

I thought I could use this to kill Nanchen, but I didn't expect that Nanchen himself was in civil strife, and even sent hundreds of thousands of troops to station in Qingcheng, as if he was afraid that Zhao Ding would take the opportunity to attack.

Is he Zhao Ding that kind of person?

All right......

yes!

But unfortunately, this time Nan Chen sent his old rival, who knew his tricks very well. No matter how he sent troops to test, he always stayed in the city and refused to come out.

As a result, he still can't find a chance.

"Oh, it's hard. Being a prince is really hard."

Zhao Ding lay lazily under the pavilion of Prince Yan's Mansion, turned over lazily on the wicker chair, and continued to sleep.

Beside him, Lu Tao held her white and soft little hands and carefully squeezed his legs.

Feeling Lu Tao's little hands.

Zhao Ding couldn't help but sigh again: "Oh, the life of a prince is so comfortable and unpretentious."

"The prince has done it, has he done it?"

However, before Zhao Ding could lie down for long, Zhang San ran over with excitement on his face.

"What happened?"

Zhao Ding glanced at Hu San suspiciously.

Recently, with the help of his eighth brother Zhao Zhe, a large number of refugees have been sent. In addition, during the battle with Wen Liang, many Nanchen soldiers were captured, allowing him to build a lot of things, such as cement factories, brick and tile factories, etc.

Construction has already started, and every process is so fast that he still doesn't know what Zhang San is talking about.

"Is it the one with mold?"

Drawing by Zhang Sanbi.

"Moldy?"

Zhao Ding was stunned and looked at Zhang San in surprise.

Zhang San said helplessly: "Your Majesty, you asked us to use the mold spots on the moldy food, and then mixed the juice made from grinding rice with the juice made from boiled potatoes, and then let us put the mold spots in it to culture

, let us later..."

"Holy shit, is it true or false?"

Upon hearing this, Zhao Ding was immediately startled. He stood up from the wicker chair and grabbed Zhang San: "Let's go, let me go with you, Lord. I'll make a fortune."

"Get rich?"

Zhang San looked suspicious.

But when he thought about the effect of that thing, Zhang San still nodded very pertinently.

Maybe you can really make a fortune with the function of that thing!

…

A back city, a factory hub, a certain warehouse.

A group of people were wearing simple masks, and several large vats were filled with unknown liquids. Beside these liquids, baskets could be seen everywhere, containing various rotten fruits with green mold, as well as unknown fruits that had already been eaten.

How long for food.

Zhao Ding took out a mask and put it on his mouth.

Then he followed Zhang San and walked into the warehouse.

I have to say.

The taste is really sour and refreshing.

Fortunately, in the few years since he first came to Youzhou, Zhao Ding had suffered all kinds of hardships, and he didn't care about the taste.

"Your Majesty."

Watching Zhang San leading Zhao Ding towards him.

The soldiers guarding the warehouse immediately bowed and shouted.

"Open the door."

Before Zhao Ding could finish speaking, Zhang San stepped forward and shouted.

As the warehouse door was opened.

A stronger and pungent smell suddenly hit my nostrils.

Everyone in the warehouse is working nervously. Everyone has a workbench with various bottles and cans placed on it.

It's very much like those laboratories in previous lives.

It is true that when Zhao Ding arranged these things, he did refer to the laboratory. Of course, it was billions of times simpler...

"Your Majesty."

"Hello, Your Majesty!"

Seeing Zhang San leading Zhao Ding in, everyone put down their work and looked at Zhao Ding to say hello.

Zhao Ding simply nodded, then looked at the old man leading him, and asked nervously: "Doctor Zhang, has the penicillin been extracted?"

That's right, the thing Zhao Ding got was penicillin.

This thing is called a miracle drug in a sense.

Especially in this era when medicine is extremely underdeveloped, if it is really figured out, it will be equivalent to Zhao Ding gaining a golden mountain for nothing.

After all, there are a lot of minor frictions between countries these days.

One can imagine the demand for something like this.

The old man known as Dr. Zhang heard what Zhao Ding said, and immediately grinned and said: "Your Majesty, of course he got the penicillin, otherwise I wouldn't dare let Butler Zhang report it to you."

"Where is it?"

Zhao Ding couldn't wait to search in the room: "Take it out quickly and show it to me. Who is that? Go get a sick chicken and let me try the effect of the penicillin we got!"

Hearing Zhao Ding's words, Doctor Zhang suddenly said with some embarrassment: "Your Majesty, those sick chickens and ducks you sent over last time are all dead."

"Oh, dead?"

Zhao Ding was stunned, "Didn't you get me penicillin? How could those chickens and ducks die?"

"It's done."

Doctor Zhang also looked at Zhao Ding with a puzzled expression, and then said with a proud expression: "Your Majesty, I have to say that this thing you asked us to come up with is so good that it kills every one of them, just in the past few days.

I asked people to go to our dungeon in Youzhou, capture a few death row prisoners, and feed them to them. They were even more effective than the arsenic, and they would die in less than an hour and three quarters."

Zhao Ding: "Huh?"

Doctor Zhang: "Huh?"

Look at the puzzled look on Doctor Zhang's face.

Zhao Ding immediately closed his eyes in pain, and shouted helplessly: "I asked you to extract this penicillin to save people, why are you fucking killing people for me? How can you do it?"

I!!!"

For a moment, Zhao Ding didn't know what to say.

Doctor Zhang also looked at Zhao Ding with an innocent look on his face: "Your Majesty, didn't you ask us to develop poison? We just did it according to your instructions. The things we extracted are really good. They are better than Hedinghong.

Arsenic, it’s much better.”

Just when Dr. Zhang was speaking.

Zhao Ding couldn't help but look inside the room.

When I saw workers carrying baskets of dead chickens and ducks out.

Zhao Ding was speechless.

How could such a life-saving poison be turned into a deadly poison by these bastards?

Amitabha.

Zhao Ding muttered silently in his heart.

Looking at the look on Zhao Ding's face, Doctor Zhang still said with excitement: "Your Majesty, after my unremitting efforts and experiments, I finally mastered a sufficient dose. Just this small cup is enough to knock over an adult.

, and it works extremely quickly, and there is absolutely no possibility of waste, even a silver needle cannot detect it!

If we see someone unhappy in the future, give him a drink, and I guarantee that he will die without knowing how he died!"

As he spoke, Dr. Zhang excitedly took out a small cup of transparent liquid from the workbench behind him and dangled it in front of Zhao Ding.

"Hehehe~~~~"
