The Daqian army also has experience in attacking Heishi Pass, and it is not meaningful to take human lives to fill it here, which is easy to defend and difficult to attack.

So they used, large trebuchets, bed crossbows, rockets......

But the gains are minimal.

The Wuguo people only left a small opening in the mountain wall for attack, and unless they shot in from here, the blow would not have the slightest effect on the mountain wall outside.

"Use the magic fire to burn them to death for this king!"

King Qi saw that he couldn't attack it for a long time, so he directly asked people to take out the alcohol.

Hundreds of machines resembling bed crossbows were withdrawn, and unlike bed crossbows, they had small clay pots with holes on either side of the pots, which were hung from special crossbow arrows with a ring.

To Yun Yu's surprise, these strange bed crossbows could also adjust their height and orientation.

Each special bed crossbow is operated by four people, an observer, a regulator, a ignition, and a soldier who imbues magic fire.

The four of them have a clear division of labor, observe the direction of the wind, adjust the high and low directions, pour in the magic fire, light the crossbow arrows, and fire the ......

With the appearance of these things, there were gradually casualties in the Black Stone Pass.

Yun Yu could see billowing smoke or blue flames coming from the dark hole.

The smell of burnt flesh and the terrible howl spread throughout the battlefield.

Yun Yu gasped and walked to the rear of the army, unable to bear to look directly at the tragic situation in front of him.

He made alcohol for the purpose of disinfecting and saving more lives.

Now it seems that it has become the god of death on the battlefield to harvest life.

When the emperor asked Yun Yu to make more, Yun Yu also thought that there would be such a day, but he didn't expect that after this day really came, he would be a little difficult to accept.

"Big dry dog thief, aren't you afraid of hurting the heavens and the peace with such a vicious thing?"

Niu Shou could no longer maintain his disdain for Da Qian at this moment, and roared hoarsely.

As long as the soldiers in front of him are stained with the blue flames, they will be burned into a charred black unidentified object, and dousing them with water will cause a bigger fire, so that more people will be engulfed in the flames.

The defenders of Blackstone Pass began to shake in their hearts.

Can such a defense really prevent the army of the Great Cadres!

Watching the robes die miserably one by one, they kept asking themselves in their hearts, if it was they who were engulfed in flames, then could they resist.

Maybe at that time, I just wanted other people to give me a good time!

"You martial arts are not afraid of hurting the heavens and the peace, what do I have to be afraid of, did you ever think that you would have such a day when you provoked the big cadres?"

King Qi is now relieved, and the resentment accumulated over the years has finally been released.

Hearing Niu Shou's voice that life is worse than death, I feel that this is the most beautiful sound in the world.

Yun Yu shook his head, this move could not last long.

Because of the limited amount of alcohol, although it was already made in full force in the last month, it couldn't withstand King Qi's creation.

The Black Stone Pass is not only tall and strong, but also has a very large east-west span, and if you really want to completely break through the psychological defense line of the people of the Wu Kingdom, you may not be able to build a winery on the spot for the King of Qi.

"Lord Wang, it's okay, if you continue like this, it will only increase the number of sins."

It's not that Yun Yu is soft-hearted, but that he has a better way.

"If you don't attack so fiercely, when will you be able to take the Black Stone Pass?"

"There are so many magic fires thrown into the gate, it is enough to burn through the city gate ten times, we can't afford such a waste."

Yun Yu was stunned when he looked at it in the back, this is the invincible King of Qi?

No wonder the seven attacks were not breached.

The reason why the Black Stone Pass is strong is because it was built by hollowing out the mountain, and the mountain stone itself is strong.

But the city gate is not good, and there is still a big gap between the man-made and the natural things.

The gate was still wooden, and if you had burned it with alcohol at the beginning, you might have gone in now.

Anyway, Daqian doesn't need this Xiongguan, does it have a big impact on him if there is a city gate?

If you directly burn the city gate, why should you keep being tough with the city wall?

"Huh!"

King Qi was asked suddenly, as if what Yun Yu said was very reasonable.

Why should I keep fighting with this impregnable wall?

The gates, which looked obviously fragile, were the best choice.

"All of them, retool, storm the gates."

The attack on the gates was effective, and in almost two hours, the gates were burned through.

The structure of the Black Stone Pass determines that it cannot have the existence of an urn city, and once the city gate is broken, there is no need to defend the entire pass.

"Rush!"

King Qi's eyes were bloodshot, and after more than ten years, he was finally able to enter the Black Stone Pass.

The 400,000 army did not need to be commanded by the King of Qi, and the moment the city gate was burned through, there were people who were not afraid of death who rushed in.

An hour later, Heishi Pass was completely occupied by the Great Cadres, and the guard Niu Shou killed himself.

The king of Qi left some people to defend the Black Stone Pass, and he led his people to continue to attack the city.

Without the Black Stone Pass as a barrier, the other cities couldn't stop King Qi and his army at all.

He went down to the Nine Cities in one day, and it was not until it was dark that he could no longer fight, and the King of Qi stopped.

"Hahaha! Yun Boy, thanks to you, otherwise I am afraid that this time I will have to return in vain. ”

King Qi is a little scared when he thinks about it now, when did he decide to be tough with the city wall that is impossible to be breached.

"Since you have promised the prince, you naturally have to do something."

Yun Yu didn't say much, but he instinctively felt that something was wrong.

There are too few guards at Blackstone Pass.

Moreover, the historical artifact that met with King Qi yesterday did not appear today.

Even if the King of Qi captured the nine cities of the Wu Kingdom one after another, he did not find the historical weapon and his 300,000 army.

I hadn't even heard that the city had asked for help from Shiqi, as if the general of the Martial Kingdom had disappeared with an army of 300,000.

"Take a break today, and tomorrow we will continue, and strive to take the entire Wu Kingdom within a month."

King Qi didn't expect the people of the Wu Kingdom to be so vulnerable, and even the defenders in the nine cities together were less than 10,000.

Moreover, the equipment is also very dilapidated, and even the equipment that the army eliminated and did not need is better than the equipment they use.

Yun Yu nodded, and the worry in his heart did not diminish by a point.

Day 2, Day 3, Day 4......

The king of Qi led his army to fight for 800 miles, but there was no opponent.

Sometimes, when the Wuguo people heard that the Daqian army was coming, they didn't even resist and surrendered directly.

This made King Qi very happy, thinking that this was a manifestation of the loss of the hearts of the Wu royal family.

If you can take all the land of Wuguo, you don't need to be educated, and these people can easily become big cadres.

Yun Yu didn't have the optimism of King Qi, he felt that the whole country of Wu was unusually united, and they didn't know what was brewing with the strength of the country.
