Six red cannons were pulled apart on the city wall with white cloth for covering them.

The gun barrel made of pig iron was dark and cold. After the shells were loaded quickly, they aimed at the locations of the catapults and fired!

Rumble!

Six deafening roars in succession, the barrel of the red-clothed cannon emitted the true blue-black smoke.

The shells streaked across the sky like a meteor, flew over the Liao army's positions, and headed straight to the location of the catapult cart in the rear of the Liao army.

But the artillery of this era is both powerful and accurate.

The bulky red-clothed cannon wanted to hit the target, except for relying on the gunner's experience, the rest can only be left to God's will.

However, the huge launch cost of the red-clothed cannon was destined to make it impossible for the court to invest too much in training the gunners' firing skills, so when the cannon was shot out, it almost completely closed its eyes and relied on the will of God.

Under such a premise, its accuracy can only be described as miserable.

The volley of six red cannons and six shells, only two of which were slightly more reliable, but they only injured two catapults. The other four cannons killed dozens of people, but the catapults were still intact.

The role of gunpowder in the current red cannon is to push huge solid shells to fly out of the barrel, causing physical damage with the potential energy of the shell itself, and gunpowder hardly participates in the explosion.

Therefore, the power it causes is extremely limited.

And, it is very troublesome to fill.

In one stick of incense, you can only shoot one volley.

The efficiency and unreliable power make the red-clothed cannon still unable to occupy the protagonist on the battlefield even though it has been around for many years.

Today, Li Chen really saw its limitations.

There were eight catapults on the opposite side. After a round of volleys of six red-clothed cannons, they all had the ability to throw stones again. Seeing that the second round of stones were about to hit, the red-clothed cannons on his side were still filling in ammunition.

This efficiency can only be effective when fighting positions and facing huge and inactive targets.

For example, the Hall of Supreme Harmony during the rebellion in the capital.

Li Chen frowned and pulled Wu Qingcang, saying, "Immediately find a group of sharpshooters with extraordinary arm strength to come over, carry the Great Qin divine thunder with arrows, and destroy the Liao army's catapult car!"

The city wall is far away from the catapult cart, and it cannot be effectively killed by ordinary means. The only deterrent red cannon also proves that its accuracy is really unreliable, so Li Chen cannon can only be treated as a live horse.

Before, Chen Tong sent a batch of Qin divine thunders, so Wu Qingcang was not unfamiliar with this thing. When he heard Li Chen's attention, his eyes lit up and he immediately ordered someone to prepare.

At this time, the second round of projection of the catapult was already running.

"Your Highness, this is really not a place to stay for a long time. A gentleman does not stand under a dangerous wall. Please come down to the city wall!" Xu Wei said anxiously.

Gripping his teeth, Li Chen glanced at the Liao army that was still rushing towards him like a tide, and said angrily: "Let's go, go down first!"

He knew that staying here at this time would not only not help, but would also drag him down.

Smart people should make the right choice at the right time. Those who know that the dangers are extremely dangerous and forcefully show the protagonist's halo and heroic character are all cerebral palsy settings.

If Li Chen raised his arms and forced himself to boost morale on the front line, the next moment, the archers and catapults of the Liao army would take him as a target and pounce on him like a mad dog.
