During my escape from famine, I survived by eavesdropping on the whispers of food.

Qin Shuangshuang was shocked and said to him, "You only stayed in that tent for a short while, how come you're telling me you're going to war in the middle of the night? Even if you did go to war, you might not be able to repel those people."

Have you thought it through?

Lu Jun nodded and said to him, "Don't worry, no matter what, I have to fight this battle. If I don't go, no one will be able to lead them."

At this moment, Qin Shuangshuang couldn't help but cover her mouth and say to him, "Don't forget, even if Lord Lin can't get out, it's not your turn."

Jin Danian is right here, isn't he? I know you want to fight the enemy together, I understand that, but have you thought it through?

"There are swords flashing and guns clashing outside. What if you get hurt?"

After much deliberation, Qin Shuangshuang felt that with a formidable enemy at hand, the fate of the nation rested on the shoulders of every citizen.

In order to protect the names and people in this area, I believe this expedition is meaningful, and we must go out no matter what.

Qin Shuangshuang had no choice but to say to him helplessly, "Then you should take good care of yourself."

She then went over to help everyone serve the soup.

Lu Jun then stepped forward and said to her, "Didn't you praise the things I made for you before? This time I plan to use them to fight the enemy."

Qin Shuangshuang thought about it and felt that the thing was indeed very good. She said to him, "Alright, you should make as many of those things as possible as soon as possible, so that they can be put to use later."

Lu Jun nodded, "I think so too. I plan to take action tonight and see if my precious weapon will come in handy tomorrow."

Seeing his enthusiasm, Qin Shuangshuang thought that since he had helped her buy time before, she should help him this time as well.

Qin Shuangshuang then took the initiative to say to him, "Since you are so keen on making that thing, I will help you."

When Lu Jun thought about how she would help him, given her skillful hands, he figured they would be able to create many of those weapons tonight, so he agreed without hesitation.

Late at night, Lu Jun and Qin Shuangshuang began manufacturing arrows inside the tent. Qin Shuangshuang watched as one arrow after another was attached to the arrows. These arrows were indeed much stronger than other ordinary arrows.

Because it can kill in one strike.

It could even prevent the enemy from getting up again, and because of its sharpness, it could potentially kill two enemies at once.

Qin Shuangshuang felt that this thing had a lot of merits, and the two of them were busy and happy inside the tent.

Jin Danian, who was outside, noticed this scene and his eyes lit up with interest. The two men were assembling weapons. He walked over and sat down next to them, asking, "What is this thing?"

After Lu Jun explained it to him, Jin Danian suddenly realized and said to him, "This thing is indeed a good thing. If it can really play a huge role tomorrow, we may make more weapons like this in the future. This will make it much easier to defend against enemies in the future."

Lu Junyi thought that his weapon had gained Jin Danian's approval, and he nodded in agreement, telling him, "That's also my intention. After all, I find the weapons on the market to be too monotonous."

Some of them are even prone to breakage halfway through the journey, so I thought I'd reinforce them as much as possible to see if I could double their effectiveness.

Lu Jun's words made Qin Shuangshuang suddenly realize something. Qin Shuangshuang did not expect that Lu Jun had such creative ability. If this were in modern times, he would probably be able to make a fortune. However, that would have to be in the modern era. Even in the 21st century, he might not be able to make a fortune.

……

By the next day, the enemy had already attacked.

The old man, riding a tall horse and wearing a hat made of animal hide with a long beard, held a crescent-shaped sword in his hand and looked down at the people on the city wall with an arrogant air.

The other side couldn't help but spout nonsense, saying, "I never thought that you people from the Central Plains would be so ungrateful. We've already reached the city walls, and you still have the nerve to close the city gates. If you ask me, wouldn't it be better to surrender sooner?"

Why must we resort to knives and guns? Are you really going to sit here like cowards, hiding behind closed doors, refusing to come out and play the hero?

The professors present burst into laughter, while Qin Shuangshuang, Lu Jun, and Jin Danian stood atop the city wall.

Looking at the arrogant people of the Waler Kingdom below the city wall, Jin Danian clenched his fist and said to Lu Jun, "Since the lord has already given you all the power yesterday, what do you think we should do now?"

The soldiers are all waiting for your orders!

Lu Jun touched his chin, scrutinizing the armor. He was wearing a suit of armor, and Qin Shuangshuang beside him was also wearing armor. Although it was bulky, she was already quite slender, and now she looked quite dashing in it.

Qin Shuangshuang looked down at the people below the city wall. There were probably several thousand people, but their army only had four thousand men. What should they do? It seemed that this was going to be a tough battle.

Lord Lu Jun told him, "We don't need to go out for now. Although they're already here, they should try out the weapon we were working on last night."

When Jin Danian thought of what he had made last night, he nodded without hesitation and said to him, "Okay, okay, I'll go get the things over here."

Qin Shuangshuang quickly saw several waves of zombies and came up with the weapons she had made the night before, placing them one after another in front of them.

Qin Shuangshuang thought that this was the perfect time to test the power of that thing. Sure enough, at Lu Jun's command, everyone fired the weapon. Then, the soldiers below the floor fell one after another, completely powerless to fight back.

Before long, Qin Shuangshuang saw their reinforcements arrive. As soon as the reinforcements arrived, they hurriedly used their shields to protect all the soldiers in front and behind them.

Even now, what Lu Jun made might not be able to penetrate that shield. Lu Jun glanced at the enemy soldiers on the city wall and saw that many of them had died, and some had even had an arrow pierce through the bodies of two people.

At this moment, Lu Jun suddenly exclaimed that the weapon he designed was indeed very good.

The enemy's Khan, seeing that his brothers had suffered some casualties, shouted at him from downstairs, "Since that's the case, then don't blame us."

Then, Qin Shuangshuang watched as they pushed several carts over, and then tried to light kerosene balls and throw them at the city wall. Qin Shuangshuang thought that those things wouldn't be so easy to block when thrown.

Just when everyone was at a loss, Lu Jun spoke up, "Since they want to throw fireballs inside now, let's give them a taste of their own medicine and let them see what we're made of!"

As soon as he finished speaking, Lu Jun clapped his hands, and several soldiers carried up a scarecrow. Qin Shuangshuang looked at this scene and suddenly wondered if this person was also a reincarnated person like herself.

This scene is too much like the story of borrowing arrows with straw boats.
