Zhao Tai wanted to offer Suzhou and Sizhou to Song Jin, which made Zheng Qingzhi very happy and thought that Zhao Tai was still very reliable.

But even though I was happy, I had a hard time accepting Suzhou and Sizhou.

After all, this is a prefecture and county of the Jin Kingdom. The Southern Song Dynasty directly took it over, which is not very good-looking. They were worried that it would be at odds with the Jin Kingdom, so the Song Army broke with the Jin Army first.

Zheng Qingzhi, Zhao Fan and others discussed and believed that the Mongols were relatively powerful and the Southern Song Dynasty had no chance of winning if they started a direct war. Therefore, they made up their mind to wait for the Mongolian army to attack Kaifeng and both sides suffered losses before launching a surprise attack.

If the Song army entered Suzhou and Sizhou too early, the Mongolian army would realize that the Southern Song Dynasty would take action.

Therefore, Zhao Tai agreed to donate, but the Southern Song Dynasty did not dare to accept it for a while.

Seeing this, Zhao Tai kept sending people to urge him. Zheng Qingzhi could only give Zhao Tai a batch of supplies to reward Zhao Tai for his loyalty, and ordered the Lianghuai Zhisi to be prepared to accept Su and Si.

August is the autumn harvest season, when people are harvesting a good harvest, but the plains of eastern Henan are desolate.

From the beginning of spring, Subutai, who was stationed in Luoyang, continuously sent cavalry eastward out of Hulao Pass to raid the plains of eastern Henan and interfere with the production of the people in the Central Plains.

Due to the plunder of the Mongolian cavalry, during the autumn harvest in August, the harvest in all states and counties in eastern Henan was generally poor.

At this time, in the eastern suburbs of Kaifeng, three thousand Tiger Cavalry soldiers were guarding thousands of carts, escorting rice from the Southern Song Dynasty, and headed for Kaifeng in a mighty manner.

After Zhao Tai received Song aid from the Southern Song Dynasty, he immediately took out a sum of grain and sent it to Kaifeng City, and took the initiative to cheer up the Kaifeng defenders. Once the Mongolian army attacked Kaifeng, he would definitely lead an army to relieve Kaifeng.

Now the situation was obvious. The Mongols would definitely attack Kaifeng. Zhao Tai and the Song Dynasty in the south knew this, so they hurriedly sent money, food and supplies to Kaifeng before the Mongols started to attack.

At this time, the transport team was marching mightily, and several Mongolian cavalry appeared in the wilderness in the distance.

They reined up their horses and stood there for a while, observing from a distance. When they saw a large number of cavalry guarding them, they turned their horses and headed west.

Not long after, Wanyan Chenghu led the Tiger Cavalry Battalion and escorted the grain to the gate of Kaifeng City. The defenders in the city hurriedly opened the city gate to welcome the transportation team from Zhongyi Town into the city.

"Wanyan Chenghu, who has humbled his post, is here to meet the Prime Minister!" Wanyan Chenghu got off his horse and saluted Yi Lapua who came to receive him.

Pu'a was quite excited when he saw the convoy entering the city, "Are these all supplies sent by Duke Zhao?"

Wanyan Chenghu nodded, "Our commander-in-chief knew that there was a bad harvest in the Central Plains and there was a shortage of supplies in Kaifeng City, so he specially ordered his subordinates to send food. He also sent a batch of firearms. I hope the Prime Minister can take good care of them."

When Yilapua heard that Zhao Tai had also sent firearms, he was even more happy and said, "Is it a thunder that shakes the sky? If it is this thing, I will definitely let the Mongols meet and bleed in the city."

Wanyan Chenghu said: "It is indeed a thunder that shook the sky. In addition, my commander-in-chief asked me to tell the Prime Minister that once the Mongolian army attacks Kaifeng, he will definitely lead his troops to rescue him. In addition, the Southern Song Dynasty will also send troops, so the Prime Minister and Your Majesty do not have to worry

, just hold on to the city."

Yilapua sighed with emotion, "Zhao Guorui is really my loyal minister of great wealth!"

Outside Luoyang City, the Mongolian general Subutai led a group of cavalry galloping through the wilderness, chasing an elk.

The war between Meng and Jin led to a sharp decline in the population around Luoyang. The fields outside the city were barren and overgrown with weeds. Various birds and beasts replaced humans and began to multiply on a large scale.

If the rulers of the Central Plains dynasty saw this scene, they would feel sad in their hearts: "The country is broken by mountains and rivers, but the city is full of greenery." However, for the nomads, they really long for such a desolate scene with wild beasts everywhere.

Because the Mongolian army slaughtered Luoyang after conquering it, there were less than a hundred households in Luoyang city. Subotai was stationed here and had no internal affairs to deal with, so he went hunting outside the city with his subordinates every day.

At this time, he shot an arrow while running, and the elk running in the distance fell down in response.

"The marshal has shot!" the Guards cavalry galloped to the struggling elk and cheered loudly.

Subotai heard the sound and sheathed his bow and arrows quite proudly. At this moment, a group of cavalry galloped up to them.

"Reporting to the marshal, we discovered that the Jin people are rushing to transport food to Kaifeng." The leading cavalry saluted and reported.

Subotai frowned. It seemed that the Jin people expected that Mongolia would besiege Kaifeng, so they tried their best to rush supplies to Kaifeng.

Kaifeng is a big city, and the more supplies there are in the city, the harder it will be for the Mongolian army to fight.

Therefore, Subotai must not let the Jin Kingdom continue to send money, food and materials to Kaifeng.

Thinking of this, Subotai said in a deep voice: "Now that the autumn is high and the horses are fat, the warriors have been recuperating for a long time. It seems that it is time to destroy the Jin. Send the order, the cavalry will come out of Hulao Pass and cut off the transportation of the Jin.

Passage, and then send someone to inform the Khan of the situation here."

On the Mongolian grasslands, thousands of war horses gallop in the vast wilderness, and countless cattle and sheep eat rich pastures on both sides of the winding rivers.

Ogedai's army retreated to the grasslands. After resting for more than half a year, Mongolia can be said to have strong troops and high morale.

At this time, in a camp where craftsmen gathered in the Mongolian royal court, Wo Kuotai and the Mongolian Prime Minister Yelu Chucai were studying firearms.

Last time Mongolia suffered a loss in firearms, many people were frightened by Zhao Tai's new firearms, which seriously affected the Mongolian army's combat effectiveness.

After Wokuotai returned to the grassland, in addition to letting his troops rest and recuperate, he immediately summoned a large number of craftsmen to set up a firearms institute to specialize in the study of firearms.

Mongolia conquered the north and south and captured a large number of craftsmen. After several months of public relations and research, we finally got some clues.

"Great Khan! The Firearms Institute has changed the formula many times, but the effect has never been satisfactory and failed to meet the requirements of Great Khan!" Yelu Chucai had a trace of depression on his face.

After Wokuotai returned to the grassland, he asked him to summon craftsmen to study explosive firearms.

After hearing Wokuotai's description, Yelu Chucai was also shocked by the Jin army's sky-shattering thunder. However, he ordered craftsmen to imitate it and constantly improved the gunpowder formula, but it could never achieve the effect described by Wokuotai.

Recently, the Firearms Institute has conducted many tests, and the explosion power is average. Sometimes, the power is improved, but when the craftsmen follow the same formula and make it again, the power is no longer good.

This made both Yelu Chucai and the craftsmen of the Firearms Academy confused, and they couldn't find the problem at all.

Wo Kuotai stared at the thunderbolt that was about to be thrown out by the trebuchet, and said in a deep voice: "Humph, now I know that what Zhao Tai used is a firearm, not a magical thing. Since it was made by man

If he can create something, then Ben Khan will definitely be able to create it. If you continue to study, I believe you will succeed one day."

Seeing this, Yelu Chucai could only nod his head, let the craftsman light the thunder, and then launch it quickly.

The Mongolian Thunderbolt is similar to Zhao Tai's. They put gunpowder into a clay pot and then wrap it with several layers of cotton.

In several months of experiments, although the Mongols did not succeed in creating a thunder that was as powerful as the Jin Army's thunder, they also learned some rules during the experiment.

The power of the thunder is not only related to the gunpowder formula, but also whether the gunpowder is tightly wrapped.
