After Gongsun Lian finished speaking, he couldn't wait to return to the barracks and draw a route for digging tunnels, which could have a surprising effect in the battle.

Seeing that Gongsun Lian was leaving, Li Xiaoyue hurriedly shouted, "Mr. Gongsun stays, I have other ideas." ”

"As soon as you hear a trick, you forget about it." Gongsun Lian hurriedly stopped and patted his head, but when he saw that Li Xiaoyue still had Li Laohan by his side, it was a matter of confidentiality, so he had to bite the bullet, "Uncle Li, I have something I want to say to Mrs. Li in person." ”

Originally, when he saw Gongsun Lian, Li Laohan was still smiling, but when he heard that Gongsun Lian was going to talk to his daughter alone, he immediately restrained his smile, and his eyes were a little more guarded.

"Gongsun boy, you are crazy! In front of me, you want to talk to my daughter alone! What is your purpose? Do you know that doing this can be regarded as abrupt to my daughter? ”

When Gongsun Lian heard this, his face was embarrassed, he really wanted to give himself two slaps, and he knew that he should not say such things in front of Li Laohan.

"Uncle Li, what I'm going to say is serious, it's very confidential!" Gongsun Lian explained, making amends for his behavior.

Li Xiaoyue couldn't cry or laugh, and patiently explained to her father, "Dad, there's nothing between me and Mr. Gongsun, don't think about it." What we're talking about is really the right thing. ”

When Li Laohan heard this, his eyes looked at his daughter with a bit of sadness!

Does the daughter want to repeat it again, don't kiss her father for the sake of a man?

Li Xiaoyue couldn't stand an iron-clad old hero looking at her with such a gaze.

"Dad, it's a matter of military secrets, I can't say it." Li Xiaoyue explained, hoping that the old father could understand.

Hearing this, Li Laohan was even more unhappy, because of this matter, his daughter actually broke up with him.

Li Laohan was reluctant to talk about his daughter, but he was not so polite to Gongsun Lian.

"Gongsun family boy, the Covenant Kingdom is coming, are you sure you don't need my help?"

"Besides, Lihua Village in Lanshan County is my home, do you think I won't swear to defend Zhenxiguan to the death?"

In two sentences, Gongsun Lian was speechless.

Gongsun Lian bowed and saluted, "Uncle Li, don't be angry, it's the little nephew who is rude." It's just that this is not the place to talk, let's go to the open space outside and talk as we go. ”

Li Xiaoyue and Li Laohan also noticed that since Gongsun Lian arrived, Qin Yuyao began to probe his brain.

Qin Yuyao thought that she was doing it very secretively, but in front of Li Laohan, Gongsun Lian, and Li Xiaoyue, these "jing" foxes, there was nothing to hide.

"Okay, just go out for a walk, it's strange that I haven't been in touch with my old relationship for a long time, and I don't know what happened. You often go to the capital, talk to me about it. ”

"Yes, Uncle Li." Gongsun Lian should get down, and the three of them went out together.

Li Xiaoyue held a fishing rod and carried a bucket, and was picked up by Niu Dazhuang in the back.

Everyone else thought they were going fishing.

Niu Dazhuang carried a bucket and a fishing rod and ran over to pack the boat first, and only the three of them were left on the empty road behind.

Li Laohan couldn't help but ask: "Say, what do you want to discuss?" ”

Gongsun Lian hurriedly replied respectfully: "Here's the thing, Li Niangzi was inspired by the explosion of fireworks and firecrackers, and suggested that the ratio of gunpowder be improved in order to increase the lethality of the explosion and the sound of the explosion...... If it is combined with the tunnel, and those explosives are still on the way of the cavalry of the Pact country by surprise, the effect will definitely be better! ”

When Li Laohan heard this, his eyes widened in shock, and he looked at his daughter suspiciously, "Xiaoyue, do you know about military affairs?" ”

Li Xiaoyue shook her head, she was just a woman who circled around men and children, and she didn't know much about military affairs and hadn't studied it.

"I don't know! Our shop in the county opened, and when the firecrackers exploded, the bamboo outside collapsed into my hands! ”

"It didn't bleed, but it pierced the epidermis! At that time, I was thinking that if the firecrackers were more powerful, my hand would bleed, and I wouldn't even be able to save this hand! ”

Li Laohan blinked, "Gunpowder is in everyone's hearts, and it is regarded as a sound and a lively thing." Xiaoyue, you think too much! ”

Li Xiaoyue smiled, "At that time, I was thinking that the reason why the firecrackers didn't cut my hand was because of the small power. ”

"Since the power is small, there must be a reason! It's nothing more than that the materials inside are not good, or the ratio is wrong. A few more combinations, a few more experiments, and there are often unexpected results. ”

Gongsun Lian thought so, "Uncle Li, I was inspired by Xiaoyue, and after I went back, I studied with the old craftsman. ”

"The truth is also as Satsuki's guess, different combinations of materials, different proportions, and different powers."

"After many experiments, we finally found one that reached the most powerful ratio with the current conditions."

Li Laohan was skeptical, "How powerful is it?" ”

Gongsun Lian replied: "Throw ten zhang away, and the place where you land is ten steps away, you will either be killed or injured." The sound of the explosion was very loud, and even if it was lucky enough to escape, the war horse would lose its combat effectiveness because of the fright. ”

"Phew!" When Li Laohan heard this, he gasped, "That's really amazing!" Throwing these explosives out of the tunnel by surprise can indeed have an unexpected effect. ”

Gongsun Lian also felt that this method was very good, "It is precisely because of gunpowder and firearms that the little nephew and the young general have some confidence." ”

After pondering for a moment, Li Laohan thought for a moment, and then looked at Li Xiaoyue, "Xiaoyue, did you have a better idea when you stopped Gongsun Lian just now?" ”

Li Xiaoyue nodded, "Yes, the tunnel does have a lot of wonderful uses, but it also has a lot of shortcomings. ”

"First of all, digging tunnels is time-consuming and laborious, and requires a lot of manpower and material resources. Failure to maintain confidentiality is often counterproductive. If you are caught by the enemy, you may be able to go straight to the city along the tunnel! ”

"Secondly, even if you can dig tunnels and throw out gunpowder on the road that the cavalry must pass, the people sent out may not be able to run more than four legs on two legs, and these people may not be able to come back."

"So in view of the above situation, I don't recommend digging tunnels out of the city. Instead of wasting time and effort digging tunnels, it was better to improve gunpowder. ”

"When the Covenant invades the Great Zhou, it will inevitably attack Zhenxi Pass, five miles outside Zhenxi Pass, is a valley that does not have a big undulation, if we can bury the explosives on the road that must be passed, and there are horses or soldiers trampling on the place where the explosives are buried, there will be an explosion, so the effect is better?"

Li Xiaoyue's words made Li Laohan and Gongsun Lian stunned at the same time.

If it can really achieve what Li Xiaoyue said, in the future, they will not be afraid of the invasion of the treaty country at all, and it is guaranteed that they will not return.

After a while, Li Laohan came to his senses and looked Li Xiaoyue up and down.

"Is this still my daughter? Why do I feel like I've changed my head? What others can't think of, you can come up with? ”
