Wuxian also had experience in attacking cities. Seeing Zhao Tai's confidence, he couldn't help asking: "Guorui, what secret weapon do you have?"

There were only three of them in the tent, and Zhao Tai's plan required their cooperation, so he didn't hide it, "It's not a rare thing, it's just gunpowder."

Wu Xian frowned. Gunpowder has been around for a long time and has been used in military applications for a long time. Wu Xian also knows a lot about gunpowder.

He has also used rockets, muskets, caltrops, poison smoke balls and other items on the battlefield. However, based on his actual experience, it cannot be said that they are useless, but they are definitely not able to influence the situation of the battle.

Zhao Tai could see Wu Xian's suspicion, and Chen Zhong seemed to be doubtful as well.

The Song army used firearms earlier than the Jin soldiers. His feelings were similar to those of Wu Xian, but they were only of some use.

Looking at the expressions of the two of them, Zhao Tai could only smile and say: "Do you think my gunpowder is useless? I said mine is useful. This is a new type of gunpowder. The power of gunpowder depends on the formula and manufacturing process. Don't look at Zhengzhou Chenggao

The wall is thick, let me blow it down for you."

"Collapse?" Wu Xian and Chen Zhong looked at each other, feeling that Zhao Tai was getting more and more mysterious as he spoke.

Seeing this, Zhao Tai knew that it was useless to talk, so he said in a deep voice: "I am going to dig a tunnel directly to the bottom of the city, and then bury gunpowder underneath to blow up a section of the city. In addition, I am also preparing for the artillery carriage.

We have acquired a new type of cannon stone. Don’t worry, we will definitely capture Zhengzhou within half a month.”

Zhao Tai's bold statement of setting aside half a month to capture Zhengzhou before setting out for the expedition was naturally not without purpose.

This was due to the fact that he had already started manufacturing gunpowder in the weapons workshop he set up in Suining.

Zhao Tai knew very well that he was no match for Mongolia now, and there was no way he could fight against Mongolia without using some strange skills.

Gunpowder was invented very early and was also used in the military. However, its main role at this time was to create noise, scare the enemy, or be used in fire attacks. The power of the explosion was very ordinary.

In order to fight against the Mongols, Zhao Tai noticed gunpowder very early and obtained a batch from the Jin Kingdom and the Southern Song Dynasty. However, after using it, he found that the power was average and the effect was very unstable.

This disappointed Zhao Tai. He found that whether it was the gunpowder of the Jin Dynasty or the Southern Song Dynasty, even if it was the same formula or the same batch of gunpowder, it would be different due to problems such as the purity of the raw materials, the manufacturing method, the fineness of the particles, and the uniformity of the ingredients.

When gunpowder explodes, it exhibits different effects.

After Zhao Tai established the weapons room, he began to make gunpowder by himself. He did not adopt any new technologies. He just asked the craftsmen to improve the purity and uniformity of the raw materials, control the fineness of the particles, and then repeated experiments to arrive at the most powerful formula.

Then formulate standards and proceed with production.

The gunpowder produced in this way not only has improved power, but also has a stable effect.

In addition, Zhao Tai was not afraid of the Mongols getting the formula, because he improved the power of gunpowder mainly by relying on management and production techniques. The Mongols wanted to follow suit, but it was difficult to achieve the same effect.

After hearing Zhao Tai's words, the two of them were skeptical, but they had no other choice but to believe Zhao Tai.

When Zhao Tai was under the city of Zhengzhou and preparing to capture Zhengzhou, news that the main force of the Jin army was advancing westward also reached the Mongolian army camp outside Luoyang City.

"Today's attack was good. Although the city gate was not breached, a section of the city wall was occupied for a time. According to this method of attack, the gold thieves in the city will not be able to last long." Wo Kuotai said with a sullen face, summarizing the experience of attacking the city.

Subotai said: "Now the soldiers share the same hatred and want to break through Luoyang as soon as possible, and then march eastward to destroy the Kingdom of Jin."

"If the warriors use their lives, no chickens or dogs will be left after Luoyang is conquered! One day, Kaifeng will be captured, and the money and women in the city will be yours to ask for. I only need Zhao Tai." Wo Kuotai nodded slightly and took a fat piece of oil.

When you put the mutton into your mouth, you will feel as if you are eating Zhao Tai.

After hearing this, the eyes of many princes and nobles immediately gleamed.

Although the Jin Kingdom had been fighting for so many years and had long been impoverished, a lean camel was bigger than a horse. As the capital of the Jin Kingdom at this time, Kaifeng still had a lot of wealth in the city.

Since they destroyed Xixia and obtained a batch of treasures, Mongolia and the Jin Kingdom have been at odds with each other in the past few years. The Mongolian nobles only fought wars, but gained little.

Now, when I think about taking Luoyang and Kaifeng and being able to rob without restraint, I can't help but feel excited.

Just when everyone was red-eyed, the tent curtain was raised, and a general entered the tent, saluted and reported: "Great Khan, Guo Dehai reported that the Kingdom of Jin sent 70,000 troops from Kaifeng."

Wokuotai raised his brows, spit out the meat he had chewed for a few bites onto the campfire, and shouted loudly: "The gold thieves are so bold, they really dare to come to save Luoyang!"

Subotai said in a deep voice: "This must be the disastrous defeat of the Eastern Route Army, which has fueled the arrogance of the golden thieves and made them have the illusion that they have the ability to relieve Luoyang."

"You don't overestimate your capabilities!" Wo Kuotai said bitterly: "If they dare to come, I will destroy them."

Subotai looked at the person who reported the report and asked: "What is the equipment of the Jin army and who is leading it?"

"The equipment of the Jin army is acceptable, and nearly half of them are armored soldiers. Judging from the flags, those who came are the Privy Envoy of the Jin State, Yi Lapua, the Marshal of the Capital Wanyan Heda, the Military Envoy of the Zhongyi Army Zhao Tai, and the Military Guard Military Envoy.

Wuxian." The visitor reported: "The Kingdom of Jin has sent over all its elites."

"Zhao Tai, Wuxian, Heda!" Hearing these names, Wo Kuotai's eyes turned red and he gritted his teeth and said, "I didn't go looking for them, but they came to me to die."

Now there are not many people in the Jin Kingdom who can fight. Monk Chen is surrounded in Luoyang, and almost all the rest come over together.

Subotai said excitedly: "Great Khan, the elites of the Jin army are coming out in full force. If we wipe them out, Kaifeng will fall without a fight."

Wokuotai nodded heavily, "Yes, as long as this Jin army is destroyed, the Jin country will be completely finished. Now that they have left Jiancheng and come west, I should immediately send a cavalry to cut off their retreat and let them

Once it comes out, it will be impossible to withdraw from Kaifeng."

Many generals nodded, and Subotai asked for orders: "Great Khan, leave this task to me! I will contain them first and don't let them shrink back to Kaifeng. It will be difficult to attack then. The Great Khan captured Luoyang.

Then send your troops eastward, join forces with the ministers, and destroy them."

Just as Wokuotai was about to agree, the curtain was raised again, and a gust of cold wind blew in, making everyone look at him sideways.

"Great Khan, the guard general of Hulao Pass has sent the latest military report. About 30,000 Jin troops have arrived at Hulao Pass, building strongholds and building long walls. It seems that they intend to prevent our army from reinforcing Zhengzhou." A man rushed in and reported with a salute.

.

Wo Kuotai was stunned for a moment, his brows furrowed. He pondered for a moment, then suddenly cursed: "Damn it, Jin Bing doesn't want to rescue Luoyang, he wants to take over Zhengzhou!"
