Soon, news came from the barracks.

The traitor was captured, but he was the remnant of Lei Ben's old department, and now he helps the enemy to pass on important information.

The Baituguan camp also temporarily adjusted the plan to attack the enemy.

Although there is a certain risk of postponement, if they can get the help of General Qiao, their chances of winning will be improved by a few points.

In the past ten days, Yi Mingxue has barely left the mine for half a step.

The weapon blueprint she gave this time was the one she used the most in the last days.

She gave the name herself.

The principle of this crossbow is equivalent to that of firearms in later generations, but because the technology of this world cannot make bullets, Yi Mingxue replaced it with a wolf tooth nail with equally strong lethality.

Although the entire crossbow body is not as light as a firearm, it is quite a powerful existence compared to other more bulky cold weapons.

When the first wolftooth crossbow is successfully assembled.

The engineer captain who led the team couldn't wait to give it a try.

He held the crossbow in one hand and pulled the trigger.

I heard a crunch crack piercing the air, followed by a thud.

A small wolf tooth nail actually hit the target accurately ten zhang away, and directly penetrated the three-layer arrow target.

The eyes of the dozens of sappers present widened in disbelief.

"This! What a crossbow bolt! ”

"If this hits the enemy, I'm afraid that three people can be annihilated on the spot!"

The crowd erupted in cheers of excitement.

"Great! We've got a chance to win! ”

"Such a powerful thing, if we can equip it with one hand, I'm afraid we won't be able to win the battle?"

"Quick, send a message to the General. Say that the armament has been greatly improved! ”

With the encouragement of this crossbow test, the enthusiasm of the craftsmen became even higher.

Especially when everyone learned that these armaments were for soldiers to use on the battlefield.

I worked even harder.

In the end, everyone worked together, and it only took eight days to complete the production of 500 wolf-tooth crossbows.

After the weapons have been upgraded and transformed, the combat power value of Qiao Xin's troops has skyrocketed.

In a few days, he really pulled out the camp and galloped to the aid of Baitu Pass.

In the end, only about 1,000 people were left in the big camp, led by Ji Rongshan, who was responsible for guarding the checkpoint on Qiyang Mountain.

……

Yi Mingxue returned to Fengyun Town.

During this time, the town became calm.

It was like the last silence before darkness came.

On this day, Yi Mingxue received a letter from the fourth Yi Tianlei.

In the letter, he changed his usual recklessness, and revealed his cautious earnestness between the lines.

But after Yi Mingxue read the letter, she was silent.

Yi Changle, who was looking at the side, twisted his eyebrows, "What's wrong?" What did the fourth child say in the letter? ”

She is now taking the place of her senior brother and teaching the new students who have been admitted to the college in recent years.

Speaking and doing things are becoming more and more mature and steady.

Yi Mingxue handed out the letter in her hand, "Look at it yourself." ”

Yi Changle quickly took the letter and read it carefully.

"The fourth is going to be a soldier? Isn't he wandering the rivers and lakes with his brothers? ”

Yi Qingqing just came in from the flower hall on the side, and quickly walked into the house when he heard the words.

"Third sister, is it the fourth brother who sent a letter?"

"Yes! But he's got a big idea now! Yi Changle said a little angrily.

"It's okay to wander the rivers and lakes, but at such a young age, you want to join the army. There are no eyes on the battlefield, in case there is something three long and two short......"

Yi Changle didn't dare to continue thinking about it.

This is the biggest concern for all military families. Especially now that it's a time of war.

Yi was lightly frightened, and hurriedly looked at Yi Mingxue with an anxious face.

"Eldest sister, what now?"

"What can I do! I think I should just tie people back! He is not yet twelve years old, and even if he wants to go into battle to kill the enemy, it will not be his turn! Yi Changle said angrily.

That expression is like a heartbroken old master.

But what Yi Mingxue was thinking about was something else.

In the original book, Yi Tianlei was in the army shortly after the troubled times.

But at that time, because of Yi Changle and the male and female protagonists, he became the deputy general of a rebel army by mistake.

In the end, he was chased and broken out by the troops led by the new prince, that is, the male protagonist.

Yi Tianlei was also beheaded for public display.

Yi Tianlei has the talent and talent to lead troops to fight, if he is destined to take this path.

It's better to help him choose a good team, maybe it can work wonders.

"The third, you write to the fourth. said that the matter of joining the army was to be discussed, but let him take the time to come back first. ”

Yi Changle didn't expect her eldest sister to agree to the fourth child to become a soldier.

Immediately objected, "Big sister! I can't let him go. He is a simple-minded and well-developed Tie Hanhan, who is afraid that he will die when he goes to the battlefield. ”

Yi Mingxue understands her calf care, but she also understands that Yi Tianlei is only afraid that her mind has been decided.

"You have the best relationship with him, don't you know him? He is a master who does not make decisions easily, and once he makes an idea, ten cows cannot be pulled back. ”

Yi Changle's expression became even more anxious, "Yes!" But he listens to you the most. As long as you don't let him go, he won't go. ”

But Yi Mingxue shook her head, "What would happen to you if I didn't let you take the exam?" ”

"I ......" At this time, it was Yi Changle's turn to be silent.

It is her ambition to pass the pre-palace examination and contribute to the prosperity and revival of the world.

If the eldest sister forcibly stops her, she ......

You can't give up no matter what!

Seeing that she was no longer silent, Yi Mingxue softened her voice and comforted her two younger sisters.

"We have to believe in the fourth child, he has been practicing martial arts in Leijiazhuang for so many years, and he is no longer a child in our eyes."

The matter was a foregone conclusion.

However, the battle began to become more and more tense.

A few days later, in the middle of the night.

Yi Mingxue received an urgent military report from the dark web.

A large force of the enemy army has captured the county head. Now, it is calling Huzhou County.

And if they want to take Huzhou County, the first checkpoint they need to overcome is Qiyang Town!

From the perspective of military fortresses, Qiyang Town is undoubtedly the throat of Huzhou County.

With its steep mountains and vast forests, these natural creations have given the local people a natural barrier.

Therefore, there will be an old city wall and a garrison.

However, in Qiyang Town today, there are only more than 1,000 troops in Ji Rongshan's hands.

This is compared to the tens of thousands of enemy troops.

It's like using a mantis arm as a car and hitting a stone with an egg.

What to do?

This was the only reaction in Yi Mingxue's mind after reading the military report.

Yi Changle was awakened by the movement in the eldest sister's room from his sleep.

So I got up and went to check.

I saw her eldest sister getting dressed and getting ready to go out.

"What's wrong?" The little girl rubbed her sleepy eyes, and couldn't help but be a little worried when she saw this.

Yi Mingxue instructed without raising her head while putting on her shoes.

"The enemy army is coming, I have to go to the military camp in Qiyang Town. Stay at home these days, and keep your doors and windows. ”

When Yi Changle heard this, he suddenly fell asleep and woke up.

She couldn't help but start dressing and putting on shoes.

"It's so late, I'll go with you!"
