“Enemy attack…!”

Many lookouts saw the dark mass in the distance.

Suddenly, a loud whistle sounded on the wall. Han Feng also raised the telescope to look. He smiled and thought, "The barbarians are finally here."

"Pass on my order, all troops, take your positions and prepare for battle!"

"Report to General Peng immediately, the enemy is attacking, the number is unknown!"

He stood on the wall, but the enemy's attack never came.

He frowned and looked through the telescope again... vaguely, the enemy seemed to be setting up camp.

These barbarians are so cunning. They are just standing outside the range of the cannons and cannot see each other's deployment clearly. I'm afraid the barbarians are waiting for the snow to stop.

He still didn't leave.

Until it gets dark.

The telescope became useless, and I could only see about 300 meters below the pass by relying on the lights on the wall.

Han Feng frowned slightly and walked towards the command post on the wall. "Call ten captains to me!"

…

…

General Tuoba Jian of the Huang Kingdom stood outside the camp, also holding a telescope and looking at the dim Yanshan Pass in the dark night.

Standing beside him were the four commanders of the Heavenly Blade Army. At this moment, the commander of the First Army, Tuoba Lan Ce, put down his telescope and whispered, "General, the enemy is in the open while we are in the dark. Can we push the red cannon out?"

“…Then push it out!”

"Every army, listen up! Before dawn, this general will stand at..." He raised his whip and pointed at Yanshan Pass, "This general will stand inside the walls of Yanshan Pass!"

Generals such as Tuoba Lan Ce received the order and rode back to the base. At a command, eighty red cannons were pushed out of the barracks under the protection of hundreds of soldiers.

Four hundred thousand Tiandao soldiers stood solemnly on their war horses in the dark night!

"Remember, place the red cannon 500 meters away from the wall and wait for the order to fire!"

In the flying snow, eighty pitch-black red cannons, pushed by the soldiers, slowly approached Yanshan Pass.

In the command post at Yanshan Pass, Han Fengzheng said solemnly, "Cook, send out your scout battalion and make sure to find out the enemy's strength! Zhao Dayuan, you have to guard the arrow tower for me. Although the enemy has no cannons, they are good fighters. I'm worried about a surprise attack. Tell everyone to keep their eyes open!"

"Duan Xiong, your unit will be responsible for patrolling the city walls and protecting the gunners. Sun Dong, I'll leave the firing to you. We have plenty of ammunition, but we can't waste it..."

After Han Feng arranged all the necessary defenses, the captains of each thousand men took the order and went out. He stood on the observation tower with a frown on his face, raised the telescope and looked into the night again.

Too bad this thing can't see anything at night.

But it's not a big deal. The enemy can only attack by force. Now the guards at Yanshan Pass have sufficient supplies, and there are 30,000 soldiers led by the cavalry captain Wu Chang stationed at the pass.

The muzzle of this red cannon can be adjusted, and it can also hit the enemy if they are close, so no matter how hard they try, the enemy will not be able to break through Yanshan Pass!

Thinking this, he turned back to the command post, but then he heard the roar of artillery fire, and then felt a shock under his feet -

He frowned suddenly. Who the hell is this?

How did the shells land on the wall of our own house?

Just as he was thinking this for a few breaths, the roaring sound continued to ring out.

He stood up suddenly, and before he even left the command post, he saw a messenger running towards him:

"General, the enemy has artillery, and the wall is under attack!"

Han Feng walked out quickly. Sun Dong was yelling, "Gunners, take your positions! Get ready to fire!"

The lookouts were so tired from holding their telescopes, but they couldn't see the enemy at all. Where should they fire their guns?

Everyone was at a loss, except Miao Renfeng, who was hiding under the arrow embankment, watching with a sly look in his eyes.

Zhao Dapao turned his head and looked at him without saying anything.

At this moment, a ball of fire flashed in Miao Renfeng's telescope, followed by a "whoosh!" sound, and a shell fell from the sky and landed behind him.

Zhao Dapao was so frightened that he pounced on Miao Renfeng and knocked him to the ground, thinking that he would definitely die here.

But……

He slowly turned his head and saw the shell lying on the wall. He immediately laughed out loud, "It's a dud. We are so lucky!"

Miao Renfeng was already sweating coldly. He pushed Zhao Dapao away with lingering fear and said, "Get in position. I might be able to find them."

He stood up again, raised the telescope, and said viciously: "These damn barbarians, where did they get the red cannon?"

"I'm afraid they made it themselves."

"I don't believe it. I'm afraid someone secretly sold it to them... Be careful,"

At this moment, he caught sight of another flash of fire. "Five hundred meters, three quarters to the right, shoot him with a cannon!"

The barbarian gunner fired the shot, which hit the wall of the pass and burst into a brilliant firework.

He grinned, "Reload, we're going to blow Yanshan Pass to the ground!"

His lookout widened his eyes at this moment - through his telescope, he clearly saw a flash of fire in front of him, and then he saw a cannonball coming at him at a high speed.

He opened his mouth wide, followed the shell with his eyes, and then...

“Ah… run…!”

He started running, and just after he took two steps, there was a loud bang behind him. The shell hit the red cannon. He suddenly felt a heavy hammer hitting him from behind. He was blown away by the blast and fell ten feet away, dead.

“Hit!”

Following the explosion, Miao Renfeng roared excitedly!

"real?"

"Why would I lie to you? I have a way."

Han Feng just happened to come over and asked, "What's the solution?"

"Ah, General, when the enemy fires a shell, there's bound to be a flash at the muzzle. We can only determine the enemy's position based on that momentary flash. We have a lot of guns, so if we bombard that general location, even a blind cat might stumble upon a dead mouse."

Han Feng patted Miao Renfeng on the shoulder and said, "This general will remember your achievement!"

Afterwards, Han Feng taught this method to all the gunners, which made the Huang people depressed.

How the hell did they find us?

We had conducted experiments before the expedition. Logically, we were the only ones who could see the other side, but they couldn't see us. However, due to the fierce bombardment from the other side, more than 20 of the 80 red cannons were lost!

Tuoba Lan Ce's heart was bleeding. The king had obtained this red cannon with great difficulty. Yanshan Pass was not captured, but the red cannon was lost. I was afraid that the king would chop off my head!

"Back off, back off... Push the cannons forward, relocate at any time, and blast the wall for me!"

This became a mobile war, and the barbarians' cannons hit the wall directly, but the cannons on the wall had lost their accuracy.
