Jinan City.

Kublai Khan stood in front of the map with his hands behind his hands, looking thoughtful.

At this time, after listening to his subordinate's report, he felt a little uneasy in his heart.

"Something's wrong!" The more Kublai thought about it, the more he thought about it, and the more he thought about it, the more inappropriate it was for Zhao Tai to station troops there.

Tasi asked: "What did the prince discover?"

Kublai Khan said with a stern face, "Based on my understanding of Zhao Tai, this guy shouldn't just watch the Great Khan besiege Kaifeng. He will definitely not sit back and wait for death, let alone resign himself to fate. He will definitely take action."

Tasi asked: "Your Majesty, do you mean that Zhao Tai will attack the Khan secretly?"

Kublai Khan shook his head, "Then he is seeking death! What I can't figure out now is that with Zhao Tai's strength, he has no ability to rescue Kaifeng, but he stationed troops in Shanzhou and made a gesture of reinforcing Kaifeng at any time.

You know, once the Great Khan captures Kaifeng, Zhao Tai will die, but he is as stable as Mount Tai in Shanzhou. This is a bit abnormal!"

Hearing this, Ta Si also frowned, "I heard the prince say so, and it's true. Zhao Tai should be in a hurry now, but he is very calm. There must be some trick up his sleeve."

When Kublai Khan thought of this, he looked serious and said in a deep voice: "What tricks Zhao Tai has, we must find out clearly, otherwise I will feel uneasy. Tasi, you immediately send a spy horse to watch Zhao Tai to death for me."

Tasi saluted, "Yes!"

…

Shanzhou, along the Yellow River.

Soldiers from Zhongyi Town and Wuwei Town were patrolling along the river, while many civilians were carrying bricks and stones to build piers and platforms on the river embankment.

These piers are located every twenty miles. After they are built, they can station a sentry, who will then be responsible for monitoring the river section and providing warnings.

At this time, more than a dozen civilians were raising the height and capping the pier. In the woods in the distance, two Mongolian scouts quietly watched the busy crowd.

"Which number is this?" the leading scout asked.

The subordinate next to him took out the pamphlet and said, "This is the twentieth one!"

"From Shanzhou to Tengzhou, one or two hundred miles away, there is a pier every ten miles along the Yellow River!" The leading scout muttered to himself, "Jin Bing's posture is completely defensive. This situation must be dealt with.

Let the prince know as soon as possible!"

At that moment, several scouts were divided into two teams, reported all the way back to Jinan, and continued to infiltrate southward.

…

In Shanzhou City, Zhao Tai and Wuxian stood in the festival hall, looking at the map.

Zhao Tai smiled and said: "There is news from Kaifeng that Wo Kuotai has been building the equipment for a month and wanted to attack Kaifeng in one fell swoop. However, it was struck by thunder and thousands of troops were lost. The attack failed again."

Wu Xiandao: "The Commander's Sky-shaking Thunder is really powerful. Not only is it amazing in sound, but it is also powerful. Once such a sharp weapon is released, the rules on the battlefield will change!"

Zhao Tai nodded, "It's already November. If this continues, I think Wo Kuotai will probably not be able to capture Kaifeng before the Yellow River thaws. Then our chance will come."

At this time, the two were talking when Wang Bin suddenly walked into the festival hall and saluted: "Commander!"

Seeing him in a hurry, Zhao Tai couldn't help but ask, "What's the matter, sir?"

Wang Bin said in a deep voice: "There is news from Kaifeng that the Mongols used thunderbolts against Kaifeng City!"

Zhao Tai was shocked, "The Mongols imitated it so quickly?"

Wang Bindao: "According to Wanyan Heda's letter, the power and explosion time of the Mongolian thunderbolts are unstable and not as good as the thunderbolts sent to Kaifeng by the commander-in-chief. However, their number is astonishing. Wanyan Heda's letter, please

The commander-in-chief sends troops to support Kaifeng as soon as possible!"

Wu Xian's heart trembled, and he looked at Zhao Tai, waiting for Zhao Tai to make up his mind.

After the Mongolian army saw the thunderbolt last time, the huge power of the thunderbolt shocked Mongolia.

Wokuotai returned to the grassland and ordered Prime Minister Yelu Chucai to set up a firearms institute to study thunder.

Under the supervision of Yelu Chucai, the Firearms Institute spent more than a dozen craftsmen and finally managed to imitate a thunder that could be put into the battlefield.

Although the Mongolian army's craftsmanship was not up to standard and the raw materials were not uniform, resulting in unstable power, they were ready for war.

Under Wo Kuotai's urging, Yelu Chu took a batch of firearms and craftsmen to the south, transported the raw materials directly to outside Kaifeng, and made them on the spot to bombard Kaifeng.

This made Kaifeng's city defense immediately tense, and Wanyan Heda sent personnel to ask for help.

Zhao Tai walked a few steps back and forth in the festival hall and suddenly stopped, "Send someone to tell Wanyan Heda that I have sent troops and reinforcements will come soon!"

When Wu Xian heard this, he couldn't help but said: "Commander, do you want to send troops?"

Zhao Tai nodded, then shook his head, "Brother, please lead your troops to Caoxian County, but the march must be slow. If you encounter the Mongolian army on the road, retreat immediately. The Mongolian army retreats, and then slowly move forward!"

…

Inside and outside Kaifeng City, artillery and stone were intertwined, and the artillery battle between the Mongolian and Jin armies had lasted for more than ten days.

On the back of the city wall are the defenders' artillery groups, and lined up outside the city are the Mongolian army's artillery groups.

Wanyan Heda stood at the top of the city. Under the city wall behind him, he threw his pole and swung it. Black shadows rose into the sky and roared towards the Mongolian artillery group outside the city, knocking a trebuchet to the ground.

fall apart.

"Okay!" Heda punched the city wall with his fist, and just as he let out a sigh of praise, he suddenly heard someone beside him reminding him loudly, "Be careful!"

Heda raised his head and saw a thunderbolt flying straight over and hitting the tower in the blink of an eye.

The Mongolian army's sky-shaking thunder hit the tower and penetrated directly, causing the tiles to crackle and fall to the ground.

Just when everyone thought it was a dumb thunder, there was a violent explosion inside the tower. The explosion of flames and air waves directly blew away all the doors and windows of the tower, and the roof completely collapsed.

At this time, the artillery groups of the two armies were firing at each other. The Mongolian army's artillery group had a numerical advantage. In the sky, cannon stones and thunderbolts fell like hailstones.

The city head of Kaifeng, as well as the streets and houses near the city wall, were riddled with holes.

However, the Jin Army's artillery group on the back of the city wall was within the blind spot of the Mongolian army's artillery group. The stones thrown by the city wall were blocked by the city wall. The Jin Army's artillery group did not suffer any losses. The gunners did not have to worry about the cannon stones whizzing by overhead.

Zhentian Lei controlled the artillery cart to launch rounds of counterattacks.

For the Jurchens in the city, Kaifeng is their last hope. Facing the attack of the Mongolian army, it is useless for them to be afraid. They can only go into battle together, men, women and children, operating the artillery carts and carrying the stones shot by the Mongolian army.

, and smashed the stones out one after another.

For a time, there was a fierce artillery bombardment inside and outside Kaifeng City.

The Mongolian army surrounded Kaifeng. Thousands of artillery carts continued to throw stones and thunderbolts day and night. The walls of Kaifeng City were smashed, the towers were knocked down, and the houses on both sides of the streets collapsed one after another.

The loud sound of thunderous explosions resounded throughout the city and beyond.

"Marshal Du, come down to the city!" Under the collapsed city tower, the Jin Army generals urged loudly.
