The sky-shattering thunder that was emitting black smoke fell, but there was no explosion.

Seeing this, Wo Kuotai couldn't help frowning and said with a dark face, "Failed again."

Yelu Chucai also had a stern look on his face, "It's the same recipe, why didn't it explode?"

Zhao Tai actually didn't make much improvement in the formula. He mainly improved the craftsmanship in making gunpowder.

A few days ago, when the Mongolian Firearms Institute was testing a formula, an explosion occurred, killing several craftsmen on the spot.

When Yelu Chucai learned about it, he was not surprised but overjoyed. He thought he had used the right formula, so he hurriedly asked the craftsmen to make more than ten samples according to the formula, and informed Wo Kuotai that the Firearms Institute might have found the formula for Zhentianlei.

Today, Wokuotai came here specially to check. Unexpectedly, the first test launch failed again.

Wo Kuotai said with a dark face, "Continue to test fire! Not every firearm of Zhao Tai's will explode."

Hearing this, Yelu Chucai could only wave his hand, "Continue the test firing!"

After hearing the order, the craftsmen immediately loaded the trebuchet with a thunderbolt, then ignited it and fired it.

The sky-shaking thunder that was thrown out this time did not go away, but made a muffled "bang" sound in the air, and finally exploded.

Outside the camp, the Mongolians grazing herd heard the noise and couldn't help but look towards the firearms yard, but they quickly went about their own business.

Obviously, they are used to the noise coming from the Firearms Yard.

At this time, the craftsmen tested several bombs in succession, and the explosion power was average, and the power of each bomb was not uniform.

Wokuotai frowned and said, "The craftsmen say it's the same formula, but the power is different. What's the reason?"

While talking, the craftsmen shot the last one, and this one fell to the ground, but it did not explode.

When Wokuotai saw this, he thought it was a misfire and was about to turn around and leave. But as soon as he turned around, an earth-shattering explosion suddenly sounded. The craftsmen who went to check were directly blown away by the air waves, and countless pieces of soil were splashed around, rising up all over the sky.

of smoke!

When Wo Kuotai saw this scene, he was immediately overjoyed, "That's it!"

Although the power was still inferior to the Jin Army's Sky-shaking Thunder, the explosion still left many craftsmen stunned.

At that moment, Wokuotai couldn't help but stepped forward quickly. Yelu Chucai and others hurriedly followed behind them, and they all came to the explosion site. They saw a dustpan-sized hole in the ground, with smoke still coming out of it.

Yelu Chucai couldn't help but ask, "Great Khan, are the Jinren's firearms so powerful?"

Wo Kuotai said in a deep voice: "It's bigger than this."

Yelu Chucai was a little frightened when he heard the words, "Such a powerful force, if it is used to attack a city and is shot into the city with a trebuchet, what will it be like?"

Wokuotai said: "Our Mongolian cavalry is invincible in the world, but attacking the city is more difficult. If such weapons can be manufactured on a large scale, who in the world can stop our Mongolian army."

Yelu Chucai said: "Yes! This is truly a divine weapon."

Wokuotai was quite happy, but he thought that the power of the Thunderbolt made by the Mongolian army was not stable, so he couldn't help but solemnly ordered, "The Firearms Institute must find out the reason why the formulas are the same but have different powers. In addition, we must continue to improve the quality of the firearms."

The power reaches the same level as the Jin Army."

Yelu Chucai said: "I will find out the cause as soon as possible and then mass-produce it. As for increasing the power, I think we can make the Thunder Sky Thunder bigger. It contains more gunpowder, so the power will naturally be greater."

Wokuotai nodded, but then said: "Increasing the amount of medicine will increase the weight of the thunder, which will affect the range of the trebuchet, causing our artillery group to be easily suppressed by the Jinren artillery group. "

Yelu Chucai said: "The humble position will allow the craftsmen to research a trebuchet with a longer range and greater power."

Wokuotai nodded after hearing this, "I am planning to eliminate the Jin in the near future, and to do so we need to attack Kaifeng Fortress. I hope that by then, the Firearms Institute will be able to produce qualified thunderbolts and trebuchets."

At present, the Firearms Institute has not solved the problem of unifying the power.

In addition, the Firearms Institute has not developed standards for the trebuchets that project thunderbolts and the fuses that control the explosion time of thunderbolts.

Therefore, it is definitely not realistic for the Firearms Institute to carry out mass production in a short period of time.

Yelu Chucai understood that there was a difficulty, but he still saluted and said: "I accept your order."

Wo Kuotai nodded, "Go and see how gunpowder is made."

Yelu Chucai asked people to clean up the scene and deal with the craftsmen who were killed, and then prepared to take Wokuotai to continue to inspect the firearms yard.

At this time, a group of cavalry galloped over, and the leader reported, "Great Khan, Marshal Subotai has sent a messenger."

The cavalryman dismounted and presented a sealed letter. Wo Kuotai immediately took it and opened it to read.

Not long after, after reading the letter, Wo Kuotai couldn't help frowning and said to Yelu Chucai: "I will inspect the firearms courtyard another day. The Prime Minister will go back to his account with me first."

The next group of people left the firearms courtyard and returned to the big tent. Many Mongolian nobles who had been summoned had already gathered in the big tent.

At this time, Wokuotai shook the letter in the air and said loudly: "I have just received the news that the Jin people are rushing to Kaifeng to transport food and ordnance. Kaifeng is a strong city. If there are sufficient supplies in the city, it will definitely be detrimental to me. Destroy the Jin. Now that autumn is coming to an end, and all the ministries have rested and reorganized, and their troops are strong, I decided to go south again to destroy the Jin."

In the big tent, many Mongolian nobles were silent for a moment after hearing the words. Apparently, they did not expect that Ogedei would suddenly summon them and announce the destruction of the Jin Dynasty.

After all, autumn has not passed yet, winter has not yet arrived, and everyone is still immersed in the autumn of the grassland.

Kublai Khan asked: "The Great Khan, Subotai, was stationed in Luoyang and harassed eastern Henan with his cavalry. Didn't he say that the grain harvest in the Central Plains was bad? Where did the Jin people transport grain and enter Kaifeng?"

Wokuotai said in a deep voice: "The grain harvest in the Central Plains is indeed poor, and Kaifeng cannot obtain supplies nearby. According to Subutai's report, Zhao Tai should be the one transporting grain to Kaifeng."

Kublai Khan frowned and pondered for a while, "Subotai's harassment of eastern Henan has had a certain effect. Kaifeng cannot obtain supplies from eastern Henan, and the city should be short of supplies. But now that Zhao Tai is transporting money, grain, and supplies to Kaifeng, it will undoubtedly It will affect our plan to attack Kaifeng. The Great Khan wants to send troops in advance, I have no objection."

Wokuotai was very happy to see Kublai Khan's support, "Kaifeng City has high walls and thick walls. If there are sufficient supplies in the city, it will be difficult for us to break through. Therefore, I decided to take advantage of the lack of supplies in Kaifeng City to go south in advance and encircle Kaifeng." "

In the past, when Mongolia attacked the Jin Kingdom, they waited until winter entered and the Yellow River froze before starting their attack.

Now that the Mongolian army has broken through the Guanhe defense line and occupied Luoyang, they have a stable stronghold on the south bank of the Yellow River. They do not have to wait for winter and can suddenly surround Kaifeng when the Jin Kingdom is not ready.

Kublai Khan asked: "How will the Great Khan prepare to attack when he goes south this time?"
