Li Yanfeng was surprised and turned to look at Shen Feng: “What a good policy, quickly say it!”

“General, please come with me!”Shen Feng led Li Yanfeng to the stack of Chengmen Street and immediately stopped in front of the dozens of barrels of Yanzhou stone fat.

“Does the general know what’s in there?”Shen Feng pointed his finger at the barrel.

Li Yanfeng smiled faintly: "This is the stone fat produced in Yanzhou City, ink making, which is very common here."

"General Li, this stone fat can not only be used to make ink, but also to kill the enemy!"Shen Feng gently knocked on the barrel with his hand, his eyes flashed, and looked at Li Yanfeng and said.

Li Yanfeng was surprised: “This stone fat can be used to kill the enemy?”

Shen Feng nodded: "Now the enemy and I are widowed, belong to asymmetric warfare, we can not only seek to kill, but should pursue face-to-face killing, so as to maximize the preservation of our own strength and eliminate the living power of the enemy!"

"Asymmetric warfare ... point of killing, surface killing, living force" Li Yanfeng stabled.

Shen Feng smiled darkly, and he just confiscated his mouth and blurted out some of the theoretical terms of modern war.

"I mean, now the two sides of the power difference is huge, we want to use these Yanzhou stone fat, piece by piece to kill those Turkic cavalry, our side can minimize casualties, in order to hold on until the reinforcements arrive!"Shen Feng explained it again.

Li Yanfeng understood this time, and was somewhat surprised: "It is something that makes ink, how to use this Yanzhou stone fat to form a piece of anti-Turbital cavalry?"

Shen Feng was close to Li Yanfeng, and took his own thoughts and dishes out.

“Is that really possible?”After listening, Li Yanfeng will doubt.

“We’re fighting alone now, so what’s the point?It could be amazing!”

Li Yanfeng nodded, the situation in Yanzhou City is indeed not optimistic, and now it is also a desperate situation, if the more than a thousand soldiers of the army with the khanate of the 50,000 Turkic army hard, a moment of kung fu will be lost, and it is not enough to last less than two days waiting for the arrival of the aid of the new side.Shen Feng's strategy, although he heard for the first time, he may be able to achieve strange results.This Shen Feng identity is somewhat mysterious, but he can cut down the first level of the Turk prince in the chaotic army, and Li Yanfeng has a feeling of not being able to say to him in his heart.

Li Yanfeng nodded his head, looked at Shen Feng and said, “As you say, let’s try!”

"General Li, in order to make full use of this Yanzhou stone fat to kill the enemy, we also need to make some equipment, I will draw the picture for you, please the city's craftsmen overnight!"Shen Feng then said.

Li Yanfeng nodded and returned to his Chinese army account with Shen Feng.

Shen Feng drew a pattern of several things on the familiar cowhide and showed it to Li Yanfeng.These things are strange in shape, and Li Yanfeng is the first time he has seen it.

“What are these things, and what are they used for?”Li Yanfeng looked at Shen Feng and asked, also with curiosity.

"Wait until I'm done, show it to General Lee!"It takes iron nails, wood, bamboo, ropes, and cowhide to make these things, and there is no shortage in the city?”Shen Feng asked.

"These things are stored in the military treasures in the city, and there are also treasures in the store in the city, there is no shortage!"Li Yanfeng quickly replied that although Yanzhou is a border city, it is also an important trading transit station in the western region of Datang, with many merchants and many goods in the city.This is also the reason why the khan of Shuo Ye Khan first attacked here, and the shortage of materials on the Turk side came to plunder.

The artisans in the city and the army were all gathered together, and immediately after getting the drawings of Shen Feng, they began to work overnight, so it was not complicated to do these things.At the moment, everyone is doing their best.

After doing a batch of things, Shen Feng took one of them every time and showed everyone how to use it.

After watching it, everyone, including Li Yanfeng, was stunned.

“Are these things you thinking about?”Li Yanfeng asked.

Shen Feng smiled, "Some of them I have seen and learned in foreign countries."

Li Yanfeng was surprised in his heart and gave birth to a lot of admiration for Shen Feng.

"General Lee, please order the whole city to bring all the stone fat here!"

Li Yanfeng immediately ordered that the sergeants and craftsmen in the city began to get busy, and a barrel of Yanzhou stone fat was transported from all parts of the city.

At dawn the next day, the khan himself supervised the battle, and all 50,000 Turkic soldiers and horses rushed to Yanzhou City.

This time, in addition to the cavalry, the Turkic array also brought a lot of ladders, building vehicles and other siege heavy weapons, followed by a large number of heavy infantry.

This time, the city of Yanzhou is inevitable!

General Shuo Ye Khan's tent is located on a mound not far from Yanzhou City, condescending, watching the vast army horse marching towards Yanzhou City.

Shen Feng and Li Yanfeng stood on the wall, watching the black pressure of a Turkic army horse close to Yanzhou City, but also with the siege heavy weapon, the face is heavy.

When the first troops of the Turks could see the gate of Yanzhou, they suddenly found that there were many stone piles on the outer space of the city.

These piles are made of small pieces of rubble, more than half the height, such as graves.Somewhat oddly enough, behind each stone heap dug a groove filled with black-brown liquid.

The first unit of the Turks consisted of heavy infantry and heavy cavalry, and it was necessary to first open a passage to the Yanzhou city walls for the attacking forces behind them, and also to cover them.

These infantry and cavalry marched slowly, and did not care too much about these stone piles, but only when the Tang army came to pay tribute to the fallen.

Seeing the advance troops of the Turks gradually approaching, the stone piles were all located in the Turkic army.

Shen Feng smiled coldly, turned to look at Li Yanfeng, and nodded his head.

“The arrow!”Li Yanfeng waved the flag in his hand.

On the wall of Yanzhou, hundreds of archers picked up the bows and arrows in their hands, and the arrows were wrapped in linen covered with stone fat.They roasted the arrows on the torch beside them, and the stone-fat linen began to burn.

The archer will fill the long bow, and then throw the arrows.

Countless rockets sprang up from the walls and flew like scattered meteors at the first Turkic troops.

However, the range of these rockets is very limited, when they reached the first unit of the Turks, it was already the end of the strong, the infantry cavalry of the first head team was in armor, and the arrows were beaten on the body as if they were hit by a small stone, and there was no more lethality.Many rockets are on the ground, but the arrows are still burning.

The Turkic soldiers laughed in their hearts: Tang Jun is wasting arrows in vain!
