Just when Zhao Guangyi was obviously impatient, the craftsman finally put the detonator in the small hole he had chiseled himself, then lit a fire, and found a stone to cover it.

In Zhao Guangyi's unexplained gaze, the craftsman ran towards them like a galloping leg, and the posture was like rushing to reincarnate, silently counting a few in his heart, and then a fierce man pounced on the ground.

Bong！

A huge explosion came, and Zhao Kuangyin was stunned to watch the rubble flying all over the sky, and even several of the gravel exploded at his feet, so frightened that he sat on the ground with his butt hanging on his ass.

"This ...... This...... Is this still gunpowder? ”

"To be precise, it should be called explosives, the second king, let's go forward and see the effect."

As he spoke, Sun Chunming grabbed Zhao Guangyi's hand, which was cold and cold, but there was no movement under his feet.

"Are you sure he won't blow up again? If we blow it up again, we can both ......."

"It's okay, a detonator can only explode once."

Zhao Guangyi nodded, trying his best to pretend to be unfazed, but his weak legs were really a little embarrassing for him, and Sun Chunming almost carried him all the way.

I saw Sun Chunming pointing to the big pit on the mountain, and said with a smile: "Second king, please look, this is the power of the new gunpowder." ”

"Strong, too strong, with this thing, as long as you use a few when attacking the city, what city will not break?"

Sun Chunming shook his head with a wry smile and said, "I'm afraid not." ”

"Why?"

"Because of instability, the purity of nitroglycerin is still not enough, so this detonator is still more afraid of vibration, if it is used on the battlefield, I am afraid that it will pierce itself before it hits the enemy, if it can solve the problem of stability, it can be tied to the arrow to directly blow up the enemy's military formation, my Great Song is really invincible in the world, but unfortunately, now it seems that there is still a long way to go, now it seems that he can only use him to blow up mountains and build roads, and the risk is not small, it is easy to blow up people."

Zhao Guangyi nodded knowingly, and said, "So, the biggest use of this thing at the moment is actually to cut Shu?" Also, this is indeed an artifact of Shu. ”

Since ancient times, there are three roads on land into Shu, one is the Golden Bull Road, one is the rice cang road, and the other is the Yinping Trail, none of which can make the people who go comfortable, the so-called less into Sichuan and no old people out of Shu, this is what is said, because between one in and one out, it is likely to be a lifetime.

Yin Ping Dao will not be said, if it weren't for Deng Ai's inexplicable roll, this road would not exist at all, but Deng Ai can do this, to be honest, it is purely due to luck, and Micang Road is actually not much better, there is no need for enemy troops to defend, just climbing can make it difficult to die, that place, even monkeys can not guarantee 100% safety, let alone war.

The only thing that can be attacked by the army is the Golden Bull Road, but it is only barely able to walk, the so-called Shu Road is difficult, it is said that this is the road, the great poet Li Bai said well, oh my mother, it is too difficult to walk, and it is more difficult to walk than the sky.

On such a difficult Shu road, an incomparably majestic Jianmen Pass was built, and there were one hundred and eight large and small Mantianzhai in front of the Jianmen Pass, which was known as the one hundred and eight large and small Mantianzhai that was difficult for birds to cross, Jiang Wei used an army of 30,000 people, and the Zhonghui who dragged it did not have a temper at all.

Compared with it, what is the Great Wall, Shanhaiguan, this kind of so-called Xiongguan created by man as a last resort, it can't compare to this natural miracle at all, when Sun Chunming traveled to Jianmen Pass in his previous life, he felt that he couldn't beat this place even if he was given an armored division, how could it be lost in the era of cold weapons?

Therefore, this time the Northern Song Dynasty intended to attack Shu, in fact, the whole country did not have much confidence, after all, Meng Chang still had an army of more than 100,000 in his hands, and the loyal army responsible for attacking Shu by land was only more than 40,000 people.

And now with this explosive, even Zhao Guangmei, a person who doesn't understand military affairs, understands that Houshu is over.

No matter how solid your Jianmen Pass is, I can't fight it, this is not to repair the Sichuan-Shaanxi Highway, it doesn't require cars to walk, as long as people can walk, no matter how big the mountain is, I just blow it up.

As for the instability of the detonator, it will definitely kill people, and in the overall situation of Zhengshu, it is nothing, no matter what, it is less than attacking the sword gate and killing people.

Isn't such a great achievement the first achievement of Shu? Such a great achievement, no matter what, can also suppress Zhao Pu.

Zhao Guangyi was overjoyed when he heard this, and said with a smile: "You spent millions of dollars to develop this so-called explosive, hehe, it's worth it." ”

Sun Chunming said humbly: "If the problem of stability can be solved, then it can really be called a battlefield artifact, to be honest, I don't know what this thing is used for other than cutting Shu." ”

"It's enough to be able to cut Shu, hahahahahaha, good, good, good, but ...... Guanzhong is Wang Quanbin's territory, if this thing is handed over to him directly, this credit is not big, how to do it, in order to monopolize this credit? ”

Sun Chunming sighed helplessly in his heart, for the entire Great Song Dynasty, it is undoubtedly the best choice for this thing to be sent directly to Wang Quanbin, as a veteran of the battlefield, Wang Quanbin will definitely be able to give full play to the usefulness of this thing, and call Hou Shu Dad.

But in this way, Zhao Guangyi can get a treasure offering at most, and most of this credit is still on Sun Chunming, which is definitely not in the interests of Zhao Guangyi, so not only can this detonator not be handed over to Wang Quanbin, but even have to hide the news and try not to let him know.

As for how many soldiers will be lost because of this, Zhao Guangyi really doesn't care.

This is also the reason why Sun Chunming is reluctant to come to Zhao Guangyi to offer treasure, he originally had another plan, but now in this situation, he can only be selfish, so Sun Chunming said: "The lower officials think that there is no need for the second king to say anything to the Privy Council about this kind of road construction, as long as he orders one or two prefects, when General Wang Lao attacks Jianmen to attract the attention of the Shu army, he will choose a random road to blow up, and then send 10,000 soldiers to appear directly in Mianyang, then the Jianmen Pass will naturally be broken." ”

Zhao Guangyi laughed when he heard this, but said: "In that place in Guanzhong, Wang Quanbin has been in business for more than eight years, and there are people who are loyal to the army everywhere, and there are not many Zhizhou that I can directly call, not to mention that I have nowhere to find soldiers, this credit, I'm afraid you don't want me to share it with Ling Lang." ”

Sun Chunming hurriedly said: "Xia Guan just put forward an idea, how to plan as a whole, naturally all depend on the second king, you to decide." ”

"Hehe, there is no more suitable person than him, so let's do it, I will let my brother send Lu Duoxun to be a transfer envoy, and the governors of Guanzhong Prefecture will cooperate with the construction of the road, and when the road is completed, let him and Han Chongxun go, although your son is young, he is also a national warrior promised by his brother, and it is not impossible to share him with such a credit."

"Thank you, the second king, for your support."

Zhao Guangyi patted Sun Chunming's shoulder with a smile and said, "Between you and me, you're welcome, I remember that Ling Lang was born in Tongju, and he hasn't officially relied on a jinshi yet." ”

"Uh...... Be. ”

"Wait for the matter of cutting Shu, let him rely on it again, with his talent, high school should be a bag to pick up things, I am in the Hanlin Academy, leave a good position for him, obviously a talent, what's the point of mixing in the Privy Council all day long."

"This ......"

"What? Brother Chun is unwilling? Or do you think I'm going to treat him badly? ”

"No, no, no, the lower official understands, I'll tell him when he comes back."

Zhao Guangyi smiled when he heard this: "Well, you, you are also a father, tell him well, no matter how willful your own children are, can you really not listen to Lao Tzu?" Okay, it's cold, let's stop blowing the cold wind here, let's go back. ”
