When the old King Huainan led the Huainan King's personal guards and the city guards to the ancestral tomb of Emperor Yu, they looked at the big pit that had been blown up by the thunder at the scene, and they were stunned on the spot.

Although they had already expected that the grassland people would use the Heavenly Thunder in the Ancestral Tomb of Emperor Yu.

But they didn't expect the thunder planted by the other party to be so powerful.

They couldn't see the Broken Dragon Stone at all now.

You must know that the broken dragon stone that seals the entrance of the underground palace can weigh more than a thousand pounds at times.

It is said that hundreds of people and hundreds of horses were dispatched to transport this piece of broken dragon stone, which shows how heavy this broken dragon stone is.

And at the beginning, it was difficult for any gold stone to destroy this broken dragon stone when it was carved, and in the end, it was an experienced stonemason who used a special technique to dig it down from the mountain.

And the dragon carvings on it took a lot of craftsmen years of painstaking efforts to carve.

But just such a piece of Broken Dragon Stone was blown to pieces by the thunderstorm, and not even a slightly larger piece was left.

"How much thunder did these prairie barbarians use to blow this place like this?"

Lu He's mouth looked at the big pit in front of him incredulously.

"It's over, it's all over, this broken dragon stone has been completely blown up!"

Old King Huainan immediately began to feel the world spinning after seeing the situation in front of him clearly, and he felt that his breathing began to become rapid.

"Your Highness, you don't have to worry so much, although the broken dragon stone has been blown up, but the corridor of this underground palace seems to have been buried by rubble."

Seeing this, Zhang Fengmu immediately reminded.

Old Huainan Wang's breathing suddenly stagnated when he heard this, and then he immediately observed it carefully.

And after he observed carefully, he found that the situation at the scene was indeed as Zhang Fengmu said, and the corridor of the underground palace was indeed completely buried by rubble.

"Hahaha! I didn't expect it, I didn't expect these grassland barbarians to bury the thunder so much, causing the tunnel of the underground palace to be buried by the broken rocks, it is really immortal, my Dayu Dynasty! ”

Then the king of Huainan burst out laughing.

"Your Highness, it's not time for us to be happy, don't forget that the steppe army is already here!"

Lu He was not too happy.

Lu He's words were like a scoop of cold water, and he immediately woke up the happy old Huainan King.

"Indeed, there are so many grassland barbarians, once they come here, they will definitely mobilize all the people to clean up these rubble, and now the stones blocking the road are not big, and it should not be difficult to clean up."

The old Huainan King, who was still excited just now, calmed down all of a sudden.

"Yes, we must find a way to keep the steppe barbarians out of the Imperial Tomb, and once they enter the Imperial Tomb, they will definitely arrange for people to dig it immediately."

Lu He pursed his lips and said with some concern.

"But now we only have more than 3,000 people, and the other side has more than 20,000 people, so it is impossible to stop the opponent's attack!"

Zhang Fengmu then said a little depressed.

"We are small, but that doesn't mean we can't stop them!"

Lu He shook his head and said.

"What are your plans, might as well come out and listen!"

At this time, the old Huainan King was also helpless in the face of 20,000 grassland cavalry.

"Actually, I don't have a plan or anything like that, but I believe that the people in the city must have discovered the fact that the grassland barbarians are planning to attack the ancestral tomb of Emperor Yu, and they will definitely come to stop each other at all costs."

Lu He immediately analyzed it for the old Huainan King and Zhang Fengmu.

"What does this have to do with us blocking the steppe army?"

Zhang Fengmu asked puzzled.

In his opinion, even if those people from Jinling City arrived, they might not be able to stop those grassland barbarians.

And the purpose of the grassland army's trip is the ancestral tomb of Emperor Yu, so they are the real target of the other party.

"In this case, as long as we can hold off these grassland barbarians for a while, then after those people in Jinling City arrive, our pressure will be greatly reduced!"

Lu He continued.

"It's easy for you to say, but how are we going to hold back the 20,000 steppe army?"

Zhang Fengmu couldn't help but look disdainful when he heard what Lu He said.

"I've got a way to do this!"

At that moment, a voice suddenly sounded.

The surrounding city guards, the soldiers, and the guards of the King of Huainan immediately drew their weapons and protected the old King of Huainan and Lu He in the middle.

"Don't worry it's us!"

At this moment, Li Yi and the others came out of the surrounding mountains and forests.

In order to prevent being discovered by the steppe people, they took refuge in the mountains and forests after briefly dealing with the scene.

Originally, they wanted to take this opportunity to take advantage of the Yin Prairie people.

But what they didn't expect was that the first to come was the old Huainan King and his party.

"It's you!"

When they saw clearly that it was Li Yi and the others, they finally breathed a sigh of relief.

Although they had sent some people to follow Li Yi to the Ancestral Tomb of Emperor Yu in advance, they thought that Li Yi and they had been killed by the grassland people because they saw the huge explosion crater on the ground and the blood on the ground at the entrance of Emperor Yu's Ancestral Mausoleum.

"Lu Shuai, Your Highness also asks for forgiveness for not being able to complete the task you have assigned, it is really a crime that deserves death!"

After Tang Minghu saw Lu He, he immediately stepped forward and hugged his fist on one knee.

"I'm not doing it well, and I ask Lu Shuai to forgive me!"

The city guards and soldiers who followed behind Tang Minghu also knelt down on one knee and then lowered their heads with shame on their faces.

Seeing the soldiers of the city guard camp blaming themselves so much, Li Yi's face also felt hot pain.

When he borrowed troops from the old Huainan King, he made it clear that he wanted to stop the movement of the steppe people.

But now they've messed it up.

"This matter was not so easy, and now seeing you alive means that you have wiped out all those steppe barbarians, and this is already a victory."

Old Huainan Wang saw that everyone was full of shame and chagrin, and he immediately stood up and comforted.

Although he was also very angry in his heart now, he could not speak out to blame these people at this time.

After all, they had fought desperately against the steppe people before, and if they reprimanded them for doing things badly, they would definitely hurt their morale.

Although the old Huainan King comforted everyone, they were still reluctant to get up for a long time.

Especially Tang Minghu, he didn't even dare to raise his head.

In his opinion, as a manly husband, he should spit a nail in one mouth, originally they vowed to prevent the grassland barbarians from destroying the imperial mausoleum underground palace.

But now they let the grassland people completely blow up the broken dragon stone at the entrance of the underground palace.

This is the loss of trust, which seems to him to be an unforgivable fault.

"Although we were not able to stop the actions of the steppe barbarians this time, it is not all your fault, I believe that you have done your best before, and I also believe that you are brave and fearless when killing the enemy."

Seeing this, Lu He immediately jumped off the horse, and then helped Tang Minghu up.

Seeing that the old King Huainan and Lu He did not blame themselves, the soldiers of the city guard camp finally felt better in their hearts.

"Boy Li, you just said that you have a way to hold back the grassland barbarians?"

Old King Huainan saw that the grassland army was coming, and his heart was already very anxious.

"That's right, although I can't defeat all these grassland armies, there are still some ways to stop them from entering the Ancestral Tomb of Emperor Yu, but this method is only temporary."

When Li Yi saw the old Huainan King asking him, he immediately said.

"Is there any way you can tell me specifically!"

Seeing Li Yi's confident appearance, Old Huainan Wang couldn't help but ask curiously.

"Actually, it's very simple to drag down these grassland troops, but you have to pay some price!"

"At what cost?"

As soon as the old Huainan King heard that he needed to pay the price if he wanted to drag down the grassland army, his face changed slightly.

In fact, it is not that the old King Huainan is reluctant to pay the price, but Li Yi said that his method can only temporarily drag down the grassland army.

Therefore, he had to test whether the price he paid was equal to that of dragging the steppe cavalry.

"Actually, the price is not big, but it depends on whether the old King Huainan can accept it."

Old King Huainan couldn't help frowning when he heard this.

As a vassal king who has been in Zongzheng Temple all the year round, they always speak in a foggy way when they talk on weekdays.

In fact, it's not that they deliberately pretend to be deep, it's just that when their identity reaches their level, every word they usually say may become a handle for others to attack them.

Therefore, they sometimes have to choose to speak in this way to avoid those with bad intentions.

And the old Huainan King now understood the meaning of Li Yi's words at once.

"Say, what pot are you going to let me carry?"

The old Huainan King didn't want to play any more dumb riddles with Li Yi, so he asked bluntly.

Li Yi was immediately surprised when he asked this.

He didn't expect that he would be heard by the old Huainan King just by saying such a sentence.

"Actually, it's nothing, now the only feasible way to drag down those grassland barbarians is to order all the grass and trees around Emperor Yu's ancestral mausoleum."

Li Yi immediately said his own method directly.

"What? Are you going to destroy the ancestral tomb of Emperor Yu? ”

After Zhang Fengmu heard Li Yi's method, he immediately jumped up like a cat whose tail had been stepped on.

And the reason why he reacted this way was because the laws of the Dayu Dynasty stipulated that all areas within ten miles of the imperial tomb were part of the imperial tomb.

And every grass and tree in the imperial tomb is forbidden to be cut down and destroyed by all the royal people, and those who violate the order will be punished with the crime of great disrespect.

In other words, these plants and trees around the ancestral tomb of Emperor Yu cannot be cut down at will, and once discovered, it is a capital crime.

But now it's good that Li Yi has burned all these plants and trees like a fire, which is simply bold and reckless.

But the old Huainan King was not angry when he heard this, but he touched his beard and thought about the possibility of this matter.

"Now there are 20,000 people in the grassland army, and it is impossible for us to prevent them from entering the Ancestral Tomb of Emperor Yu, but if we can set all the surrounding plants and trees on fire, this will inevitably lead to a mountain fire in the entire Zhongshan Mountain, and the Ancestral Tomb of Emperor Yu in the midst of the mountain fire will be protected by the mountain fire."

Li Yi pointed to the surrounding trees and said loudly.

And the old Huainan King and Lu He looked around one after another, and felt that although Li Yi's method was a bit extreme, it was really useful.

Once the mountain fire burns, the ancestral tomb of Emperor Yu surrounded by a sea of fire will be unbearably hot, and if the wind direction does not change, the ancestral tomb of Emperor Yu may be shrouded in smoke from the mountain fire.

At that time, no matter how bold these steppe barbarians were, they would not be able to risk their lives to rush in.

Because whether it's the heat or the smoke, it will kill them.

"Although your plan is good, but look at the surrounding grass and trees, they are still green, I am afraid it is not easy to cause a wildfire, right?"

Zhang Fengmu saw Li Yi talking eloquently, he couldn't help pouting and said.

"Master Zhang Xingwu may not understand the knowledge of this grass and trees, these trees planted on Zhongshan are all pine trees!"

Jingzi was seeing Zhang Fengmu questioning Li Yi everywhere, and he immediately stood up and said for Li Yi.

"What about pine trees? You see, the leaves of these pine trees are still green, how can this be ignited? ”

Zhang Fengmu saw that Jingzi was saying this, and he immediately pulled a pine branch beside him and said loudly.

"Pine trees are very easy to ignite, even green leaves can ignite, and pine trees contain a lot of oil, so when burned, a lot of smoke will come out!"

As Zhang Fengmu's boss, Lu He couldn't stand it anymore, and he explained directly.

Zhang Fengmu couldn't help but blush when he heard this.

He originally thought that he had seized the loophole in Li Yi's plan, but he didn't expect that the other party had already thought of this.

This somewhat embarrassed Zhang Fengmu.

Li Yi didn't care about this, he just stared at the old Huainan King and wanted him to give an answer.

In fact, he could have done this directly, after all, it was not difficult to set fire to the surrounding trees, but anyone with hands and feet could do it.

But after all, this matter is against the laws of the imperial court, and there is no need for him to be sentenced to death in order to protect the ancestral tomb of Emperor Yu from being destroyed by the grassland people.

"If the old King Huainan is unwilling to bear this charge, I can bear it!"

Just when the old Huainan King was hesitating, Mu Junhe held his sword and said with a disdainful face.

When the old Huainan King saw Mu Junhe say this, he suddenly felt that his cheeks were a little red.

You must know that although this Mu Junhe has severed relations with the royal family, in the final analysis, he is still in the Nanyu lineage.

Although this matter is a capital offense for outsiders, it is not a problem at all as a person of the Mu family.

And once this matter spreads, it is likely to become a beautiful talk for them to break the enemy with wit.

Therefore, when this troubled era is about to arise, the old King Huainan does not want such a good opportunity to slip away in vain.

"Junhe, you are a junior after all, of course this kind of thing is fought by us elders!"

Old King Huainan looked at Mu Junhe with a smile.

"Humph! Old fox! ”

Seeing that the old Huainan King had such an attitude, Mu Junhe couldn't help but sneer.

The old King Huainan was not angry at all.

"In this case, you have quickly set fire to the surrounding trees, and we will let the grassland people watch the Ancestral Tomb of Emperor Yu go further!"

Immediately, the old king of Huainan waved his hand and ordered everyone to start lighting the fire.

All of a sudden, whether it was the personal guards of the King of Huainan or the city guards, the soldiers took out their own fire folds and began to set fire around the ancestral tomb of Emperor Yu.
