Lu Kang was lucky, the explosion happened at his feet, the big white horse he was riding was blown up, Lu Kang was overturned to the ground, the thick soil completely buried him alive, and several personal soldiers dug him out with all hands and feet.

Lu Kang coughed violently a few times, his face was as white as earth, and the serial explosions tended to stop, but the resulting shock still made people feel like the world was spinning. Rao is Lu Kang is well-informed, and he didn't understand what was going on just now.

Is it an earthquake? It's not quite like, although Lu Kang has not experienced an earthquake, but he also knows from the book that the earthquake is just a shaking of the ground and mountains, and it will not have such a great lethality.

If it was an earthquake, it would never have been so powerful, let alone an earthquake that is rare in a hundred years could happen here so coincidentally? If it wasn't an earthquake, it must be Liu Yin's masterpiece.

Thinking of this, Lu Kang couldn't help but feel a chill, although it was not clear what kind of weapon Liu Yin used, but if this powerful weapon was really mastered by the Shu army, it would definitely be a nightmare for the Wu army. In modern times, the most powerful weapons are nothing more than catapults, crossbows, siege engines and the like, and I have never heard of any weapon that can make a loud noise and be deadly, and it is simply an unfathomable power to kill and injure so many people at once.

The earth-shattering explosion also made Zhang Xianhe, who had already passed through the valley, shocked. Even if they tried to break their heads, they couldn't figure out what was going on behind them. The voice. It's like a thunderbolt. But how could there be thunder on this staring day? What's more, the thunder did not come from the sky at all, but seemed to burst out from under the earth.

Zhang Le over there was already laughing, it was not the first time that Zhang Le had seen such a large formation, the last time he was on the top of Jingjun Mountain, Deng Ai had tasted the power of stone thunder, and this time it was replaced by Lu Kang.

"Hahaha. This time it's enough for him to drink a pot of Lu Kang, not to blow up his intestines and stomach, but also to blow up his missing arms and legs, it's really relieving! ”

This stone thunder array was arranged by Liu Yin earlier, although Liu Yin was not sure that the Shu army would be defeated, but it would not be wrong to plan ahead of the rainy day.

Although Liu Yin commanded three battalions of officers and soldiers, the firearms such as stone thunder grenades were only in the hands of the Liu family's private army under the command of A Jian. First, Liu Yin was worried about the leakage of the gunpowder formula, after all, this thing was Liu Yin's unique secret weapon. It is safe only in the hands of the most trusted people, and the second is that these firearms are only the primary application of gunpowder, and before the birth of musket artillery, the application range of these weapons is still greatly reduced, except for the use of specific places, it cannot be used in a wide range of all-weather use, and the third is that the production is also limited, and it is not enough to equip the whole army. Therefore, Liu Yin attaches great importance to firearms, and specially compiles a song for soldiers as firearms in the private army, which is personally controlled by Ah Jian.

This time, the stone mines were buried in the valley east of Yuxian County, which was naturally carried out by Ah Jian himself, and Ah Jian had already buried all the stone mines before the two sides of Wu and Shu entered the war. This place is the only way to go west to Yun County, and Liu Yin's hope is useless, but it turns out that Liu Yin's vision is still outstanding.

Before that, Liu Yin secretly told Ah Jian, asking him not to be in a hurry to arrange the detonation of the stone mine, and after the Wu army's front team passed, the fuse was lit when the team entered the valley, and Liu Yin's target was directly aimed at Lu Kang.

If Lu Kang can be solved, it can be regarded as revenge for Zhuge Zhan, and at the same time, the crisis of Wu army's invasion will be eliminated by half, although Yong'an will not be able to get it back for the time being, but Chengdu is really safe.

Of course, whether it can be achieved or not, it depends on luck, after all, what Liu Yin planted is only a stone mine, not a precision-guided bomb.

After the stone mine detonated, Liu Yin immediately ordered the Tiger Cavalry Battalion to charge, and at this moment it was the time when the Wu people were frightened, and they could be caught off guard by seizing the opportunity.

Deng Pu, Zhang Le, and Zhao Zhuo immediately led a cavalry to rush over, but Zhang Xianhe Bu Yan couldn't resist the enemy and retreated in a hurry. The cavalry of the Tiger Cavalry Battalion had a poor level of cavalry and archery, and the impact power was not as fierce as the Yongliang cavalry of the Wei State, otherwise, none of the vanguard troops led by Zhang Xian and Bu Xian, which was mainly infantry, would have a chance to escape. However, Rao was like this, and the Wu army was beaten up when he first entered the camp, and fled back to the wolf-ridden valley in embarrassment, colliding with the Wu army's brigade.

Liu Yin took it when he saw it, and he didn't chase after it, and when he saw that the tiger cavalry battalion had attacked near the valley, he immediately withdrew his troops from Mingjin.

The biggest advantage of the cavalry is that it has strong mobility and comes and goes like the wind, but it is only a moment, and the tiger cavalry battalion has already withdrawn and moved away in the direction of Wangqi County.

Zhang Xian and Bu Yan went to see Lu Kang in disgrace, only to find that Lu Kangcai was really discouraged, and it is no wonder that Lu Kang was dug out of the soil by his own soldiers, and it is strange that he is not discouraged.

Lu Kang was not intimidated by Shi Lei, although he still did not know what weapon Liu Yin used, he still ordered the Wu army to advance towards Yuxian, but this time he was much more cautious, step by step, and only after finding out the truth did he march again.

Liu Yin's tiger cavalry battalion was much faster, and soon caught up with the large army, and from a distance, you could see the tall city tower in Yuxian. Yu County is the seat of the county seat of East Guanghan County, and it is also the only way from Jiangzhou to Chengdu, so its strategic location is very important, and the city is strong, much larger than the general county seat.

And this time the entire army of grain, grass, baggage, and ordnance are piled up in Yun County, so that Zhang Zun led the troops to guard in Yun County, the defeated Shu army in the field is now in urgent need of a city to settle down, seeing the tall city wall, the heart of the Shu army is naturally a lot more steady.

However, what makes all the Shu army strange is that outside the east gate of Yu County, there is actually a large camp, from a distance, it seems that there are a lot of people and horses, it stands to reason that Zhang Shoucheng is not possible, how can it be impossible to put troops outside the city, can it be said that the Wu people sent troops to make a detour to attack Yu County?

Everyone sighed in their hearts, there were interceptions and chasing soldiers in front of them, and it was really not easy to enter Yun County.

However, the sharp-eyed soldier saw that it was not the flag of the Wu army flying in the barracks (to be continued). )
