In addition to the three-eyed musket, Lin Xu also built the first cannon in Daning!

This kind of artillery refers to the red cannons from the previous life. Although the red cannons seem to be a bit low-level, with the current craftsmanship and materials, it is impossible to create such high-end thermal weapons.

However, the cannons he designed and manufactured were much stronger than the Red Cannon in terms of power and mobility!

A more important point is that when he made artillery, he used complex annealing, quenching and other processes to deal with different parts of the artillery, and also used high-strength alloys. Therefore, this artillery basically does not explode the chamber, avoiding the situation where he injured his family due to the explosion during combat!

Using this kind of artillery combat, whether it is frontal combat or siege, its power is conceivable!

It is no exaggeration to say that in Daning, which is mainly composed of cold weapons, the three-eyed flintlock guns and cannons are all dimensionality reduction attacks!

However, Lin Xu also faced a problem, that is, although the three-eyed muskets and cannons were made, they can only be regarded as laboratory products at present. There is still a long way to go before mass production and to equip Lin Shanjun soldiers as conventional weapons!

In addition to the breakthrough in firearms, Lin Xu also made a huge breakthrough in the medical field, that is, after continuous research, he finally created the first syringe in Daning!

Although the shape is a bit rough and cannot be compared with those syringes that cost a few cents a day in the 21st century, the syringes made by Lin Xu can also be injected normally intravenously!

He took the local dogs at home to experiment several times. After confirming that there was no problem, he brought a syringe and artemisinin to inject Fang Jinglan!

Although Fang Jinglan was still unsure of this strange treatment method, he still chose to believe in his third brother!

As a result, after several treatments, his condition improved significantly!

After diagnosis, Doctor Xi confirmed that Fang Jinglan's condition was indeed gradually degrading. This really surprised and happy them. At the same time, they were admired by Lin Xu's magical treatment!

When Fang Yulin saw that Lin Xu could really cure his father's illness, his attitude towards Lin Xu also took a 180-degree turn. Every time he saw Lin Xu, he would scream "third uncle, third uncle", which was so sweet and smooth!

......

That afternoon, Lin Xu was staying with Zhang Lie and others in Linshan Village, continuing the mass production process of public relations fire guns and cannons. Chen Qingyu suddenly ran into the laboratory and said, "Sir, something happened to Mr. Guo!"

"What happened?"

"He took the troops in the palace to the post station to fight with people!"

"Who did Lord Guo go to war with?"

"It is said that this person is the third son of Lord Liu Mingju!"

"Mr. Guo took the troops from the office to fight with Mr. Liu's third son?"

Lin Xu refined the words Chen Qingyu said for a while and asked in confusion: "Qingyu, are you right?"

"Sir, this is what the County Magistrate Wu sent to say!"

"Where are people?"

“It’s just outside!”

Lin Xu took off his gloves, raised his legs and walked out.

Outside, a soldier was waiting anxiously, but Lin Xu knew this person, his name was Otian.

"Oda, what's going on?"

"Sir, that's the case. Today, Lord Liu Mingju's third son passed by Jiangling and lived in the post station! The postmaster received the reception according to the rules, but Mr. Liu San despised the standard of reception too low, so he actually asked his followers to tie up the postmaster and beat him up! After Lord Guo heard the news, he took the mansion soldiers to the postmaster and confronted Mr. Liu San!"

"Do you confirm that he is Lord Liu's third son?"

"He has a Investigation and Relationship issued by the Ministry of War, and a road guide. It is written very clearly. It is sure that it is Mr. Liu San!"
