The big guy travels through the book and becomes the female supporting role, torturing the scumbag a

Today's blast furnaces are already capable of producing very good quality steel. I have also studied ancient military equipment and plan to improve it and create some firearms that are simple to use and have good power.

I originally wanted to take it one step at a time, but now it seems I have no choice but to speed things up. Fortunately, I have trained some craftsmen, and even if I don't go to Hejian Prefecture, I can have them oversee the production of improved weapons."

Xie Ying couldn't help but give him a thumbs up: "You're really good. You brainwashed them so quickly?"

Situ Yuan corrected him dissatisfiedly: "Don't talk nonsense, I just used knowledge to influence them."

Xie Ying rolled her eyes at him in disdain, then continued to ask, "What weapons have you improved?"

Situ Yuan said, "It's nothing. As long as you have good steel, you can make good quality sabers, arrows, spearheads, and armor. In addition, good steel can also be used to make cannon barrels. Have you heard of the Tiger Crouching Cannon?"

This mortar was used during the Ming Dynasty. However, due to the lack of high-quality steel, the barrel had to be made very thick to prevent it from exploding. Even so, the barrel's lifespan was short. Furthermore, the shells were also inferior, resulting in limited damage.

If alloy steel is used to make the gun barrel, it can be made thin enough to reduce the weight of the entire barrel and facilitate movement. The improved artillery shells can also greatly increase the lethality.

"As long as we set up mortars on the city walls, we can stop the enemy cavalry. The fragments from the shells will not only kill the cavalry and horses, but also terrify the remaining horses, making it difficult for them to continue fighting."

Xie Ying nodded with satisfaction: "That sounds good, but if they choose to attack in winter, will their artillery shells be affected?"

Situ Yuan analyzed: "Although the winter in Hejian Prefecture is cold, it is not extremely cold. It is probably only minus five or six degrees Celsius, so it won't have much impact.

Even if the enemy wanted to attack, they wouldn't choose a cold weather day, as their cavalry and horses are also afraid of the cold."

Xie Ying finally felt relieved. "So, as long as we have these improved weapons, we will have a huge advantage. Even if the enemy really attacks, we don't have to be afraid of them."

Situ Yuan said, "That's right, so the most important thing now is to find the thief! Hejian Prefecture has been relatively stable over the years. It doesn't make sense that it was suddenly breached by the enemy, with the garrison commander and the prefect dying tragically.

There must be traitors colluding with the enemy! If these traitors are not found, Hejian Prefecture will never be stable."

At the end of his words, he clenched his fists tightly, and his whole body was filled with murderous intent.

"The traitor should indeed be arrested." Xie Ying sighed softly, "Unfortunately, I can't leave for the time being, so this matter will have to be done by someone else."

Situ Yuan quickly said, "I will write to my grandfather. There must be a traitor in the army. He must be found."

Xie Ying thought of the plot in the book and couldn't help but ask, "Did you know that your grandfather had a younger brother?"

Situ Yuan immediately understood what she meant: "Do you suspect there's something wrong with him?"

Xie Ying raised her lips sarcastically. "Anyway, the story I know is that your grandfather and uncle died tragically, but that man and his son survived and later adopted their grandson to your father. In the end, your adopted brother helped Chu Jiangtian rebel, and angered your father to death."

Situ Yuan's expression instantly turned extremely ugly: "Really? Then he is indeed a big suspect."

Seeing that he had murderous intentions, Xie Ying stopped provoking him.

Anyway, she has said everything she needs to say.

Situ Yuan knew all this and would definitely not let that family have an easy time.

As it turned out, her guess was right.

Situ Yuan took action quickly.

First, he asked the craftsmen to create improved military equipment samples and presented them to Emperor Taihe, which made Emperor Taihe very happy.

Then Situ Yuan took the opportunity to persuade Emperor Taihe to send several craftsmen to the Hejian Prefecture Arsenal to assist the Arsenal in building new blast furnaces, smelting steel, and creating improved military equipment.

At the same time, Situ Yuan also found out about the situation of his great-uncle and told Xie Ying privately.
