The reason why I felt like this was because before that, Guo Xiama had been ravaged by the Mongols for too long and had been angry too many times.

So when he saw the Song army's artillery fire and started to hit these Mongolians this time, the general would naturally feel extremely happy.

I guess you gave a lumberjack in the Southern Song Dynasty a chainsaw. The carpenter's mood was probably what he was like now! At this moment, there were only bumpy bullet troughs left on the battlefield. After the smoke of gunpowder was gone, the bodies of six or seven thousand people fell outside the fortress, ranging from 1,500 to 2,500 meters.

At this moment, all the Mongolian generals turned their attention to Temujin, wanting to see what means this Khan would use to seize the fortress in front of him.

At this moment, in the Thunder Fortress, everyone's eyes turned to a warrior named Chen Sigou... This guy was on the 36-meter-high watchtower. The reason why he occupied this good position was because this guy was born with a loud voice.

The four looking outposts on the watchtower would turn around and tell Chen Sigou about the enemy movements they saw.

Then this guy with a thick neck and a big voice would inform the enemy of the situation down through the iron horn in his hand.

Now he was on the top of the tower and shouted downwards: "The enemy retreated from all sides... and re-arranged the formation ten miles away!"

"There is a large amount of metal light flashing in the south, and it is suspected to be an enemy artillery. It stops from moving from 12,000 meters away... 3,500 meters away from the other side of the Lightning River in the northwest, vehicles began to move forward, with a number of 300!"

Hearing his words, Yu Jie in the command room below stared at the combat map on the table. Bu Yucheng quickly marked the position Chen Sigou said just now.

At the same time, the bloody hand Liu Ming next to them looked at the picture, and then said without hesitation: "The Mongols started attacking me from the south, preparing to use a large number of artillery to attack the Thunder Fortress."

"The one who provided them with cover were three hundred large vehicles in the northwest. They wanted to release smoke to cover the fortress and take the opportunity to cover the Mongolian army in the south to rush over and fire."

"That's right!"

Yu Jie nodded and immediately agreed with Liu Ming's judgment.

Yu Jie looked at the map marked with countless marks and said softly: "...Let the first, second, fifth, and second, prepare for the cannon."

When Liu Ming heard his words, he immediately became energetic and asked Yu Jie: "Our heavy artillery?

Are you trying to attack the enemy's artillery positions southward?”

"No" Yu Jie smiled and shook his head and said, "Since they plan to use smoke to block our sight, then just stop looking at anyone, let them see the smoke of our Song army!"

"Let the heavy artillery on the northwest city wall prepare red phosphorus smoke bombs..." "Yes!"

Liu Ming immediately accepted the order without hesitation and walked out with a smile.

In fact, Liu Ming's qualifications and level are higher than the two commanders in this fortress and a little older.

But this is the case in the army. As the commander-in-chief of the fortress, Yu Jie has to listen to anyone in the fortress during battle.

After hearing the order that the red phosphorus bombs were ready to be loaded, the young men also smirked and pulled the red phosphorus bombs out of the underground ammunition depot, and placed neatly around the gun positions.

What is this red phosphorus?

Do you still remember Shen Mo was using the trick of the mother Li in Fengle Tower in Lin'an?

That thing is red phosphorus! This chemical can emit irritating gas when burned, which is extremely irritating to the mouth, nose and respiratory mucosa.

In addition, excessive inhalation can lead to severe breathing difficulties, heavy smoke for a long time, and even death.

In previous wars, the Mongols often used two methods to offset the range and power advantages of Shen Mo's army's weapons: one was night attack and the other was smoke covering.

Just imagine, after so long, how could Shen Mo's army not come up with a countermeasure?

So this time, when the Mongolians pushed hundreds of trucks of oil-drinked wood, charcoal and pine branches, covered with wolf dung that was easily smoked, and were preparing to re-use the same trick.

They didn't know that they were about to face the scene and ushered in another dangerous smoke! Liu Ming, the commander-in-chief of the artillery, who was standing on the north wall, always looked up at the top of the watchtower.

On that watchtower, except for a loud messenger and his iron horn.

There are also large observation telescopes fixed on the platform in four directions, southeast, west and north, and are operated by four looking-up hands.

In addition, there is a weather vane made of silk at the top of the spire.

At this time, Liu Ming quickly calculated the relationship between the location, distance, and wind direction of the enemy's fireworks in his mind.

His purpose was to throw the red phosphorus smoke bomb directly into the position of the enemy's smoke-discharge troops.

At the same time, the smoke generated by red phosphorus cannot blow back to the Thunder Fortress along the wind direction.

Otherwise, the toxic smoke will also cause damage to the defensive forces in the fortress.

After calculating, Liu Ming reported the precise coordinate data to the artillery team, and then he ordered twelve artillery cannons loaded with red phosphorus smoke bombs and fired immediately! As the firing order was issued, one, two or five high-level artillery fired the red phosphorus cannon shells at the enemy group.

Then, in the northwest of the Thunder Fortress, the smoke convoys that had just lit the firewood on the car and were about to rush forward were immediately shrouded in a strange light yellow smoke!......For many years, Shen Mo's arsenal has made a lot of preparations for the Mongolian tactics.

The cannon-fired flares and red phosphorus smoke bombs are specifically used to restrain the Mongolian army's shielding tactics.

In ancient times, unlike modern armies, they could be equipped with infrared observation equipment that could see through smoke and night vision equipment that could still see the enemy's movements in the dark.

So the way Shen Mo thought of to deal with the darkness was to use cannon flares to illuminate the sky.

As for the smoke... Since you can't see through or disperse it, then you can use poison to fight the poison! If you want to cover me with smoke, so that I can't see clearly, I will use poisonous smoke to add another layer to you! In this way, no matter whether it is the artillery position of the Mongolian army or the charge troops who come up under the cover of smoke, they will lose their combat effectiveness under the smoke.

At the place where the red phosphorus smoke rose, if they didn't run away, they could really cough to death in the smoke!... This is the case this time. With the strong northwest wind, the Mongolian army's smoke-drafted carriages lit the flames and were running forward happily.

Prepare to stuff the burning smoke truck under the nose of the Thunder Fortress along the wind.
Chapter completed!
