The Ming Dynasty started with caution

Emperor Hongzhi showed an incredulous look.

Malaria has caused a sharp decline in population and barren fields throughout the dynasties. Such a serious disease has a cure in my hands.

He looked at the green pill and smelled a strange grass fragrance that made people sick.

It is definitely medicine.

He asked suspiciously: "Have you ordered someone to try it?"

Yan Chengjin shook his head: "It has not been tried yet. There is no one suffering from malaria in Beijing."

It needs to be taken to the army in the south to know. He is not sure. It is this medicine on the elbow.

When Emperor Hongzhi heard this, his fiery eyes faded by half.

All the officials looked at each other, and no one refuted.

Malaria is equivalent to a terminal illness. If you get it, you will die. It would be strange if it can be cured.

Yan Chengjin continued: "This green pill is not pure enough. It needs the help of Zhang Yuanxi, who is proficient in alchemy."

He is a man who keeps his promises.

Since he promised Zhang Sheng, Zhang Yuanxi was taken back to Beijing and sent to the Imperial College, and never came to Liangxiang again.

Zhang Sheng's mouth twitched suddenly, and he said angrily: "Nonsense! When will my son make alchemy?"

That's what only a dog-skinned Taoist would do, isn't this an insult?

I don't believe Yuanxi would do such a thing.

After returning to the Imperial College, Yuanxi didn't know how well-behaved he was, and never mentioned Liangxiang again.

What he didn't know was that Yan Chengjin and Zhang Yuanxi also had a deal. As long as he returned to the Imperial College obediently, he would one day realize his dream of becoming an engineer openly.

Li Dongyang, Xie Qian and others showed sympathetic eyes. My son was just a little bit of a fight, but Brother Qizhao's son even learned to make alchemy.

Yan Chengjin shook his head, making alchemy is so vulgar, it's called chemistry.

This is the essence of the country.

However, the ancients didn't know much about chemistry and went astray.

Chemistry is an orthodox knowledge in ancient times and should be carried forward. Jiajing is a chemistry enthusiast.

It is glorious to make elixirs, but shameful to take them.

"Mr. Zhang, that is chemistry, which cannot be confused with alchemy."

It is not alchemy, Zhang Sheng snorted angrily.

Emperor Hongzhi pondered for a moment and put the green pill back into the box: "The soldiers in the south are in dire straits, let Zhang Yuanxi try it and send the medicine to Liuzhou Prefecture. If it can really cure malaria, I will reward you handsomely!"

Zhang Sheng was worried. If he disagreed, he would disregard the lives of the soldiers in the south. If it can really cure malaria, my son...

"Your Highness!"

Yan Chengjin lowered his head and thought, and agreed to Zhang Yuanxi's request, which was half fulfilled.

In fact, chemistry in ancient times was very developed.

It's just that people in various dynasties used it for the wrong purpose, so it could not be well developed.

Taking this opportunity, it is just right for people all over the world to distinguish chemistry from alchemy.

In fact, chemistry can be regarded as alchemy, but alchemy is not necessarily chemistry.

In the Imperial College, the Five Classics Doctor is teaching at the university.

Zhang Yuanxi shook his head and sighed secretly. The lecture notes of the Imperial College were indeed a hundred times more boring than those of Liangxiang Science College. No, ten thousand times more boring.

Lord Yan always kept his promises. He was respected by Chief Engineer Song and Chief Engineer Wang. He would help him realize his dream one day.

And all he had to do was...

"Yuanxi, come with me." Zhang Sheng appeared outside the teaching building without any warning.

He was the Minister of Rites and in charge of the Imperial College. In order not to alarm the chief priest and doctors, he deliberately wore a Confucian robe.

When he arrived at a secluded corner, Zhang Yuanxi bowed slightly and said, "Father, what do you want from me?"

"The court asked you to make an elixir."

Zhang Yuanxi was confused and didn't react for a long time.

"There is malaria in the south. You and Wang Ji need to make Qingwan."

Lord Yan!

It must be Lord Yan who is mobilizing!

Zhang Yuanxi was very excited, with a light in the corner of his eyes, and choked up: "Lord Yan is really a trustworthy person!"

Hmm? Zhang Sheng's eyes suddenly became as sharp as an eagle's. Why did he feel like he was making a deal?

Five days passed in a flash, and the ten days agreed with Emperor Hongzhi were up.

Yan Chengjin entered the palace to report: "Your Majesty, the refining of Qingwan cost a total of three thousand taels, all paid by the Liangxiang Chamber of Commerce. This money..."

Hu Dalong has taken Qingwan southward, and will be able to reach the southern camp within two months.

I don't know how long the humidity in the south can keep the medicine, so Zhang Yuanxi also went south so that he could refine it at any time.

He didn't care about the mere three thousand taels of silver. This time he came to get a permanent job.

Emperor Hongzhi raised his eyelids. He came to ask me for money before he was cured of his illness.

"It has been two months since Mr. Yan's family supervised the Censorate?"

Seeing Yan Chengjin pondering and not answering, Xiao Jing smiled and said: "Reporting to Your Majesty, February 21st."

Yan Chengjin looked up at Emperor Hongzhi, not knowing what he meant.

Emperor Hongzhi flipped through the memorial and said lightly: "Go back, I know."

...

South, Tuntian Camp.

Forty-eight white tents are hidden in the green mountains and forests, with only a few patrolling soldiers, and the camp is dead silent.

In the tents, many soldiers are lying.

The personal soldiers came to report: "Captain, the old man didn't make it."

This place is really weird. People who stay overnight will fall ill in a few days.

Ma Qin took a deep breath and sighed: "Bury it. Pass on the order of this captain to withdraw and camp three miles away from here."

Three miles away is also considered a jurisdiction, not a deserter.

Now, we can only hope that the court will issue an order to withdraw as soon as possible, or withdraw to Liuzhou Prefecture.

...

Liangxiang's waterway,

A large ship slowly sailed into the bay. It was huge.

The waterway could not accommodate it. The waves hit the surrounding canal boats one after another, almost overturning the two canal boats and a yellow boat on the side.

"brute…"

"Where did this big ship come from? It has six masts. It's so big!"

"It's not a merchant ship from Liangxiang. A merchant ship from Liangxiang has a pass and a business name on the canvas, but this ship has nothing."

The sailors on the boat were confused. Looking at the writing on the boat, it didn't look like a merchant ship from the Ming Dynasty.

The shadow of the big ship covered half of the river, and all the watercraft went into the shadow.

Gao Feng stood at the bow of the boat, a little excited. I, Gao Feng, survived the catastrophe and am back!

Yan Chengjin deceived His Highness, saying that north and south are connected and east and west are connected.

Pooh!

At the end of the east, there is clearly a deserted dense forest, bigger than the Ming Dynasty, and full of jackals and wolves. Fortunately, I took people there.

"Eunuch Gao, I leave it to you to do what the king has entrusted me to do."

"Don't worry, we will report it to His Majesty."

When Gao Feng went to sea, he knew that Yan Chengjin had a plan. He was more thoughtful than the other three.

After spending all his greedy private wealth, he secretly bought a pirate ship in Tianjin Port and hired thirty sailors as retinues before he dared to go to sea.

In the tenth year of Hongzhi's reign, King Shangzhen sent an envoy Dong Min to pay tribute, and it was he who introduced Dong Min to the palace for an audience.

When he arrived at Bajiao Island, Dong Wen recognized him and gave him great courtesy.

Under his persuasion, King Shangzhen also sent a team of people to escort him out to sea.

"Stop the boat quickly!"

The river swayed, and the boats were floating left and right like fallen leaves in the strong wind, uncontrollably.

More and more tank boat owners are cursing.

Gao Feng was very happy to hear this. After two years away, Liangxiang was still so lively.

According to the prince's order, he went to the east to explore and fulfilled the order.

"We are the only ones who came back alive."

Speaking of this, he was a little excited.

Boom!

The boat hit hard, shook violently, and hit the rocks!

The sailor hurriedly came to report: "Father, the ship is broken."

Gao Feng turned around and rushed towards the cabin nervously. He saw river water gushing out of the cabin, and in an instant, it was up to his ankles.

We were about to dock and dock.

"The hole isn't big, just fill it up with some mud."

The sailors opened the lid of the bucket, took out a dark object, as thick as a book, and patched it up on the hole in the ship.

The people on the dock were watching the excitement.

The offended owner of the tanker just wished that it would sink immediately. He was not familiar with the waterways of Liangxiang, so he dared to go on a rampage?

Liangxiang, small courtyard.

Yan Chengjin was tinkering with mosquito-repellent incense. It was not difficult to make incense in the Ming Dynasty, and most of it was sandalwood.

Mosquito-repellent incense was available in the Song Dynasty. It was made from realgar and mugwort leaves, and the formula was not pure.

Zhang Xian came over and said, "Sir, a six-masted ship has arrived at the port and is about to sink."

Yan Chengjin didn't like to join in the fun and concentrated on seeing how he could make incense: "Why do you need to report it to me?"

Zhang Xian was about to say something but stopped: "I'll wait until the next official to see it. The captain of the ship looks like the eunuch of the East Palace, Gao Feng!"
