My reborn husband and son are thinking about how to kill me every day.

"It's done?" Ji Yunshuang was pleasantly surprised and immediately stood up, saying, "Then I'll go take a look now."

The oil tank she asked Qiu Lao to make was actually called the "Fierce Fire Oil Tank," which was a type of continuous-fire flamethrower invented by ancient people in her time.

However, the era she traveled to was still entirely the era of cold weapons.

People fought entirely with swords and guns.

If they were to manufacture the incendiary tank, it would be a devastating weapon for their army.

"Not only are the oil tanks finished, Ambassador Lu said the repeating crossbows are also ready. However, they may not be able to make the quantity you need in a short time unless we provide them with more help."

The Ambassador Lu mentioned by Wei Shen is Lu Wuzheng, whom Ji Yunshuang appointed after he was promoted to the rank of Lieutenant General and established the Weapons Bureau.

The position of Ambassador of the Ordnance Bureau was mainly responsible for the manufacture and maintenance of ordnance.

Wang Erniu was appointed as the deputy commissioner of the Ordnance Bureau, mainly to assist the ambassador in the manufacture and maintenance of military equipment.

After their promotions, both of them felt a bit dizzy and incredulous.

Before enlisting in the military, the two were only thinking about how to survive! They never expected that they would become officers so soon after joining the army.

However, Ji Yunshuang also told the two that their current official positions were only bestowed upon them by her, and the imperial court might not necessarily recognize them.

But that's alright. As long as they achieve results, the imperial court will not only recognize them but also give them higher positions.

The two of them now trust and admire Ji Yunshuang the most, and they believe everything she says without a doubt.

Recently, both of them have been working with great enthusiasm, even trying to save time for eating and sleeping, and devoting it as much as possible to the production and research of weapons.

Upon hearing this, Ji Yunshuang's joy deepened. She turned to Lu Yinheng and said, "Come with me to try out the repeating crossbow."

The repeating crossbow that Lu Wuzheng made this time was different from the one he made at home last time; this time it was a straddle crossbow.

The crossbow is cocked by stepping on it with both feet, and then triggered by a rope to shoot the enemy.

This crossbow had a longer range than the arm-drawn crossbow. In Ji Yunshuang's view, it was practically the earliest sniper rifle.

Most importantly, the crossbow has a low learning curve; it can be learned to use in just a few days, making it more suitable for new recruits.

When Lu Yinheng was a general in his previous life, he discovered that it would take at least five or six years to train a soldier into an archery expert, which led to a severe shortage of archers in the camp.

He had tried many times to change this problem.

Unfortunately, he was unable to accomplish this in his previous life.

When he saw the booklet that Ji Yunshuang gave to his second brother, he paid the most attention to the blueprints for the crossbow.

Now that he heard that the crossbow had been made, he was actually even more excited than Ji Yunshuang.

Upon arriving at the makeshift armory, they immediately went to see the newly manufactured crossbows.

He held it up and gestured, saying, "It's quite small; it should be usable even on horseback."

Ji Yunshuang nodded and said, "It is smaller than a crossbow. You can ride a horse and try it out later."

More than the crossbow, she was concerned about the oil tank. Therefore, she planned to check the oil tank first before trying out the crossbow.

Her weapons bureau was set up temporarily, and the premises were very rudimentary. However, Fu Ci had all the tools that Ji Yunshuang needed brought over.

Although the venue was rudimentary, it has now been transformed into something quite presentable.

Qiu Guyou saw Ji Yunshuang and a hint of smugness on his face. "Come and see, did I do the right thing?"

Ji Yunshuang was quite satisfied with the appearance. The oil tank that Qiu Guyou made was exactly the same as the one in the blueprint.

The key now is to see if the cabinet is completely sealed, and whether the liquid poured in can be sprayed out.

But it must be said that this old man's forging skills were truly superb, and he was also very clever.

Ji Yunshuang made no attempt to hide her admiration and appreciation, "This is exactly what I wanted, Master Qiu, you are amazing."

Qiu Guyou looked at Ji Yunshuang with disdain. He pulled off the gourd containing wine from his waist, removed the cork, took a sip, and said, "What else is difficult? Just bring it over. Let's see if there's anything in this world that this old man can't make."

Looking at him, Ji Yunshuang inexplicably thought of the eccentric old man in a famous TV series, and she wanted to laugh a little.

She suppressed a laugh and said, "No rush! Right now, it just looks exactly as I requested, but whether it's successful or not, we'll have to test it to know."

"How do we test it?" Qiu Guyou also became interested. To be honest, although he had made the oil tank according to Ji Yunshuang's requirements, he didn't really understand what it was for.

Because in this era, not only were weapons backward, but even kerosene had not yet been discovered.

Qiu Guyou never imagined that Ji Yunshuang intended to pour oil into the container and use it to attack the enemy.

Ji Yunshuang also knew that people in this era had not yet discovered oil. Therefore, it was certainly impossible to use oil for experiments at the moment.

She said, "Have someone bring water. Let's check if the oil tank is leaking first, and then test the range."

Wei Shen hurriedly said, "Master, I'll go fetch water."

Just as Ji Yunshuang and the others were fetching water to test the blazing oil tank, Xie Liang finally put down his chess piece, intending to meet his newly accepted female disciple.

Upon hearing that Ji Yunshuang had come to the Weapons Bureau, Xie Liang brought Fu Ci directly here.

When the two arrived, Ji Yunshuang was testing the high-temperature oil tank.

The water sprayed from the nozzle hit the two men directly.

Xie Liang reached out and wiped the water from his face, then stepped forward and asked, "What are you doing?"

"Master, Third Senior Brother, you've come at just the right time. Take a look at the new weapons I had made."

She needed the two of them to help her solve the problem of raw materials, Ji Yunshuang called out to them affectionately.

Fu Ci stared at the smile on her face, momentarily stunned. She wasn't angry about him sending people to follow her?

She didn't notice? Logically speaking, it's impossible that she didn't notice!

Fu Ci was completely baffled. He suppressed his questions for the moment, "What kind of weapon is this?"

Xie Liang also looked with great interest at the strange-looking thing in front of Ji Yunshuang.

"This is called a 'fierce fire oil tank'!" Ji Yunshuang explained to the two of them. "Look, you fill it with oil, then light it, and it can burn the enemy."

Ji Yunshuang's words made the blood boil in everyone present. At the same time, everyone had their own thoughts.

With such a magical weapon in the army, wouldn't they utterly defeat the Qi army?

Wei Shen and the others looked at him with admiration.

Fu Ci felt his blood boil again. If this weapon really worked, they wouldn't have to worry about the Qi army, or even the other sides.

However, a question arose in his mind again. How could she know so much at such a young age?

While Xie Liang was excited, he also sighed inwardly, realizing that he really couldn't teach this disciple.

This disciple knows more than he does.

Lu Yinheng was also excited, but amidst his excitement, he looked at Ji Yunshuang with some worry.

Isn't it too dangerous for her to be so sharp and outspoken?
