Back at the camp, the security guards of Qingfengju began to make explosives bags, of course, the power of simple explosives is too small, Qin Yu asked Chai Lingwu to get some iron nails, and the fragments were mixed in it, so that an explosion bloomed all over the ground, and the power was great.

One after another spiced explosive packets were made, simple and fast, of course, this thing was extremely afraid of fire, Qin Yu gave a death order, prohibiting fireworks, violators were beheaded, and no one disobeyed this order.

It is not for nothing that Qin Yu only asked the security guards of Qingfeng Ju to make explosive packs, if there are too many people who know about this thing, if it spreads out and is known by people from hostile forces, the consequences will be unimaginable, and the security guards of Qingfeng Ju can make it to prevent these secrets from spreading to the greatest extent.

At least judging from the performance just now, the security guards already have an almost blind worship of Qin Yu, and they will definitely follow Qin Yu's orders.

The weight of the explosives package limits the way and place of use, you can set up an ambush, you can throw it down from the mountain, but if you throw it directly, people with little strength can't do it, and if you don't throw it far, you will blow yourself up.

Qin Yu's subordinates have the strength to throw explosives bags a hundred meters away, and there are only thirty-two people, plus stones, Qin Yu, Cheng Huaimo, and Chi Baolin, and there are only thirty-six people, a small war is okay, but when encountering tens of thousands of Tuyuhun troops, this is not safe.

In order for everyone to achieve the maximum kill and damage to the enemy, after Qin Yu arrived in the next town, he directly bought a clay pot and a basket for measurement, and put some iron pieces and nails in it, and made an earthen grenade, no way, the conditions are limited, and it is black powder, so it can only be done like this.

Qin Yu wanted to get some missiles and machine guns directly, but unfortunately, this goal was still a little far away, but there was no hurry. Just these grenade explosives bags made of black powder are enough for Tuyuhun to drink a pot.

Practicing throwing, making explosive bags, grenades, and buying materials for reproduction, it was delayed for two days, but Qin Yu was not in a hurry, even if Li Shimin knew that he had gone to Tuyuhun, he would not be able to find himself for a while.

Explosives pack bombs were made a lot, and nearly 500 people made these things. One person can make about 300 explosive packs or 600 earthen grenades a day. If it's not for the safety of the people. Qin Yu told the security guards to slow down, and the efficiency would be improved.

In this way, each person carried fifty or so explosives bags, one hundred and ten grenades. Carried by horses, the entire powder magazine was moved.

It's not that Qin Yu doesn't want to continue, but he can't help it, if he delays it any longer, it is likely that he won't be able to pass the border pass, after one person tried to throw out an earthen grenade, the sound of "boom" kept sounding, the security guards of Qingfeng Ju were better, and those who threw this thing for the first time There are still soldiers in the courtyard. Qi Qi was stunned on the spot.

All of them had their legs swinging, even those soldiers were no exception, and it was only now that they understood what Qin Yu had given them, and everyone regarded it as a spell. Didn't you see it explode as soon as you threw it out, and the thunder was nothing more than that.

No way, these people are in contact with this for the first time, so they have this feeling, Qin Yu is regarded as an immortal again, Qin Yu has the heart to explain, but after seeing the fanatical eyes of these people, he finally gave up this plan, even Changsun Chong and others think so, what is the use of explaining.

And what is facing is the entire Tuyuhun, the army is more than 100,000 or 200,000, with the support of this fanatical faith, the combat effectiveness of these people must be soaring, and they are not afraid, this is the perversion of fanatical believers, but Qin Yu is not ready to fool these people, if it is an outsider, forget it, this is a compatriot, Qin Yu doesn't want to mess around, and after the battle, just explain it.

Chang'an, Fang Xuanling finally came back, and the car didn't stop when he arrived in Chang'an, and rushed directly to the palace, accompanied by Lu Ziyuan, the commander of Yongnian County.

In the palace, Li Shimin looked at Fang Xuanling, whose face was full of bruises, and was stunned for a moment, "Fang Aiqing, this is?" ”。

Fang Xuanling didn't care about explaining this, bowed down, and said very anxiously, "Your Majesty, quickly send someone to stop Qin Yunfei, this kid has taken someone to Tuguhun." ”。

Li Shimin was stunned when he heard this, and hurriedly asked, "Aiqing, I'm confused, didn't Yunfei go to Yongnian?" Why did you go to Tuyuhun again? ”。

Fang Xuanling immediately reacted, he was a little anxious, and after calming down, he hurriedly said, "Your Majesty, the things over there were done by the Tuyuhun people, and there was a wave of Tuyuhun soldiers with a number of eight hundred hidden there. ”。

"After the minister read out His Majesty's holy decree, this kid actually misinterpreted His Majesty's meaning and took people directly to Tuyuhun."

"What!" Li Shimin stood up suddenly, and shouted in surprise, joy and anger.

The joy is that Qin Yu took the guards to kill the eight hundred Tuyuhun soldiers, and the surprise is that after Qin Yu received the decree, he really did what the holy decree intended, and led people to Tuyuhun, which made Li Shimin have the idea of wanting to slap Qin Yu a few times, Qin Yu is such a smart person who ignores the hidden meaning of the holy decree, but Li Shimin can't be blamed, how uncomfortable and uncomfortable it is.

The anger was because Tuyuhun had infiltrated the Tang Dynasty unknowingly, and there were eight hundred soldiers, which was worth it, even though these people were destroyed by Qin Yu, Li Shimin could not control his anger, and shouted angrily, "Fu Yun!" ”。

"Your Majesty, Fu Yun is not worried, but Qin Yunfei and these boys have all gone to Tuguhun, and they are all guards, and the only soldiers who can fight are the five hundred Yulin Army brought by the minister, Your Majesty, quickly send someone to recover this kid." Fang Xuanling bowed and hurriedly spoke.

Li Shimin's brows furrowed when he heard this, Yu Lin Jun was a royal guard, but now he actually left with Qin Yu, what is this called.

Seeing this, Fang Xuanling hurriedly explained the situation that day briefly, of course, what Qin Yu said, after Li Shimin heard this, the suspicion in his heart disappeared in an instant, his fists were clenched tightly, and he looked at Fang Xuanling without blinking and asked, "Qin Yunfei really said that?" ”。

"Yes, Your Majesty." Fang Xuanling bowed and answered.

"Whew." Li Shimin exhaled a long breath and said in a deep voice, "Descendants of Yan and Huang! Yellow Blood! I finally got it! I see! He is not loyal to me, but to the Tang Dynasty and this nation! ”。

After Li Shimin finished speaking, he looked up to the sky and sighed, with a little loss, but he smiled again for a moment. "Hahaha, this world is still mine, Qin Yunfei is loyal to the Tang Dynasty, and he is also loyal to me!" , At this point, he was immediately paused, and then shouted at Yang Gonggong, "Quickly send someone to the frontier and inform the general guarding the customs that when you see Qin Yunfei, you must bring this kid back to me, he can't die!" ”。

"Yes. Your Majesty. Gonggong Yang hurriedly bowed in response. Hurriedly ran out. Find someone to go to the border pass.

"Your Majesty, Tuyuhun entered the Tang Dynasty by a secret passage, and this secret passage must be destroyed." Fang Xuanling suddenly thought of something, and hurriedly spoke.

Li Shimin heard this. was taken aback, this is not good news, of course it is not because of Qin Yu, but Tuyuhun actually dug a secret passage to avoid the inspection of the border guards, and when he thought of this, a cold air came out of Li Shimin's back.

Can you not be cold-cold, if there are so many secret passages, Datang will be defenseless for Tuyuhun, and Tuyuhun will invade on a large scale. Datang is in danger, as soon as he thought of this, Li Shimin's fists clenched tightly, and he shouted, "Tuguhun!" ”。

"Someone. It is rumored that Li Jingcheng bit gold and came to see me! Li Shimin took a deep breath, and then opened his mouth to drink.

Not long after, Li Jingcheng bit Jin Qiqi and came to the palace to meet Li Shimin, Li Shimin said directly, "I want to lead troops to destroy Tuyuhun, how many soldiers and horses do I need, and how much time does it take to prepare?" ”。

Li Jing was slightly stunned when he heard this, bowed, and then said, "Your Majesty, to destroy Tuyuhun, you need to mobilize at least 100,000 troops, and it will take at least a month to prepare for heavy preparations." ”。

"What? One month? When Li Shimin heard this, his brows suddenly twisted, obviously, Li Shimin couldn't accept it at this time.

Li Jing bowed, and then said, "Your Majesty, it is not difficult to prepare the weapons needed by the 100,000 army, but it is estimated that it is a little difficult for the grain and grass ministers, and now the weather is getting cold, once it is winter, if you don't prepare more clothes to keep out the cold, it will be difficult to survive the night on Tuyuhun's side." ”。

"I'm afraid that before the troops are dispatched, they will begin to lose their troops, even if they have clothes to keep them warm, their combat power will be reduced by at least thirty percent, Tuyuhun is different, they have already adapted to the local environment, so, minister, it is not recommended to send troops now."

When Li Shimin heard this, he sighed for a long time, what Li Jing said was the truth, Li Shimin also led soldiers, so he naturally knew this, but this breath did not come out, and Li Shimin couldn't swallow the breath in his heart.

"Your Majesty, for now, let's solve that secret passage first." Fang Xuanling saw that Li Shimin was a little irritable, thought about it, and then bowed down and said.

Li Shimin sighed for a long time, then nodded, and said to Cheng Yanjin, "Zhijie, you lead the troops to the border pass and destroy the secret passage, Fang Aiqing, you tell Zhijie the location." ”。

"Yes, Your Majesty." Fang Xuanling bowed, and then told Cheng Yanjin the location of the secret passage, as for the location of the secret passage, it was offered by the Tuyuhun general, there was no way, this person was frightened by Qin Yushi and the others, for fear that if he didn't tell it honestly, he would be killed without hesitation.

It's a pity that this Tuyuhun general still did not escape the fate of being beheaded in the end, Li Shimin carefully inquired about Yongnian's aftermath, and even the face of the Tuyuhun general was not seen, and he directly ordered someone to push this Tuyuhun general out of the noon gate and behead it to show the public.

And at this time, Cheng Biting Jin and Li Jing also knew about the amazing move made by Qin Yu and others in Yongnian, and what surprised them even more was that Qin Yu actually ran towards Tuyuhun with less than 3,000 people, this time Cheng Biting Jin was not light, without saying a word, he ordered 10,000 troops to rush towards the border pass that day, and only brought three days of dry food, Cheng Biting Jin was ready to arrest Qin Yu and others back at this time.

It's a pity that Qin Yu and his entourage have already arrived at the border pass, and the border pass general doesn't know Qin Yu, but he knows Cheng Huaimo and Changsun Chong and others, so he hurriedly raised his hand and signaled the border pass soldiers to put down the weapons in their hands, no way, who told Qin Yu and his party to carry weapons and wear armor.

The general guarding the pass looked at Cheng Huaimo and Sun Chong and the others with some doubts, and asked, "What are you Xiaolangjun doing here?" ”。

Qin Yu smiled slightly, then rode forward, raised the holy decree in his hand, and said, "Your Majesty has a decree and orders me to wait out of the customs to face the battle." ”。

The general guarding the pass sent someone down to take the holy decree in Qin Yu's hand, and after taking a closer look, he was stunned for a moment, the holy decree was true, but at this moment, no one from Tuyuhun came here to disturb him, so he naturally didn't understand.

Seeing this, Qin Yu immediately shouted, "The general doesn't have to be confused, Tuyuhun has infiltrated the Tang Dynasty, a few days ago, we have already destroyed a wave of 800 Tuyuhun soldiers, the general doesn't believe it, you can send someone to check ten miles south of this place, there is a secret passage that Tuyuhun secretly dug." ”。

The general guarding the pass was shocked when he heard this, if what Qin Yu said was true, then he was guilty of dereliction of duty, and if he was not good, he would lose his head, thinking of this, the general guarding the pass, hurriedly led people out of the customs, came to Qin Yu and the others, frowned and asked, "What General Dingyuan said is the truth?" Is there really a secret way? ”。

"That's true, but the general doesn't have to worry, those who sneaked into the Tang Dynasty have been destroyed by Qin, and the general only needs to destroy the secret passage." Qin Yu smiled and nodded and said.

The general pondered for a moment, then nodded, and said in a deep voice, "Okay, please also ask General Dingyuan to take the last general forward." ”。

Qin Yu nodded indifferently, and then took a general to the secret passage dug out by Tuyuhun, of course, accompanied by a hundred security guards and Zheng San, came to the place, Zheng San pointed to a place covered with weeds, and the security guards immediately opened the weeds, and a hole appeared in front of everyone in an instant.

The general still didn't believe it, Qin Yu said, gritted his teeth, and then sent someone down to see if it was really the same as Qin Yu said, this is the secret passage dug by Tuyuhun to infiltrate the Tang Dynasty, an hour later, the soldier came back with a frightened face, bowed down and said, "General, there are indeed Tuyuhun soldiers stationed on the side of the secret passage, the number is more than 100, I didn't dare to stay longer." ”。

When the general heard this, his face turned dark, Qin Yu shrugged his shoulders indifferently, and then said to the security guards, You go and put ten explosive bags and blow up this secret passage.

The security guards bowed in unison and said, "Yes, General." Immediately ten people came out, with ten explosives bags into the secret passage, after some arrangement, Qin Yu took everyone away, and after the security guards came out, then ignited the fire, when the general guarded the pass did not know why, "boom boom" A series of explosions came, the ground suddenly shook a few times, and the secret passage that still existed just now was sealed by the soil in an instant.

"This, this." The general opened his mouth wide and pointed to the secret passage that disappeared without a trace.

"Some gadgets, okay, Qin still has a will, it's inconvenient to stay for a long time, say goodbye." Qin Yu smiled slightly, and then rode away, the general guarding the pass was stunned, glanced at Qin Yu with fear, and then rode away.

Qin Yu and his entourage went out of the customs smoothly, and two hours later, a fast horse galloped over, holding a token and asked, "Has Qin Yunfei and Little Master Qin been here?" ”。

"It's here, it's already out." The general guarding the pass naturally knew the token in the hand of the man on horseback, and after being slightly stunned, he spoke.

"Ah, how is this good, Your Majesty wants you to block Grandpa Qin, and you must bring him back to Chang'an." , The soldiers who came to intercept Qin Yu shouted with a tangled expression.

"What!" The general was taken aback when he heard this, opened his mouth and shouted, patted his head after speaking, and said helplessly, "What can I do about this."
