After giving the order, Eugen returned to the edge of the city wall with a confident smile on his face.

From this position, he could see the whole picture, and every battle that took place on the battlefield could fall into his eyes, and above the moat outside the city walls, Tariq's soldiers were like reptiles, trying to climb up the ladder to the city walls.

The soldiers of the Guardian set their swords in their path, and the Guardian Walls were on guard to stop the fierce reptiles that climbed upward.

For everyone on the field, this is a matter of life and death, an accident, a mistake, a long sword stabbed in secret, can bury their lives.

Each of them was in the middle of it, fighting for reasons they understood or didn't understand, and Eugen, he stood higher up, watching what was happening before him.

This battle seems to have nothing to do with him, and he is the one who sees it most clearly.

What he could see was where the light could reach, and what was buried in the dirt, hidden under the snow, mixed in.

There are certain laws that are difficult to sort out, hidden secrets, victorious fighters, and hidden dangers of defeat, and Eugen sees all of them more clearly than others.

Right now, in the midst of the sight of Tariq and the Saxon soldiers, there were Eugen's prepared planes, countless powders sealed with animal skin and white wax, in clay pots, buried in the mud and snow on both sides of the moat.

If Tariq were standing in Eugen's position, he would clearly see two marks, the marks left by the freshly turned dirt.

After Tariq saw this, he only had to think about it a little, and he must have been able to guess something and adjust his tactics.

It's a pity he couldn't see it, and as for the Saxon soldiers, they saw it, but they didn't think about it.

In modern warfare, another extremely important tactical idea that has arisen along with positional warfare is mine warfare.

Landmines are definitely one of the nightmares of all land arms, and there are dangerous traps hidden on seemingly unremarkable roads, waiting for reckless boys to break into them for unknown reasons.

Acquired by Margaret's previous efforts, the warehouses of Lybor City were stockpiled with large quantities of gunpowder, which were closely guarded as important strategic materials.

This time, Eugen ordered the men to take out half of the gunpowder from the warehouse, seal it all and put it in clay pots, and make simple earthen mines.

In the past few days, two thousand ordinary citizens of the city of Lebor had participated in the production of nearly 50,000 earth-made mines.

At the moment all these mines were buried on the banks of the moat, and the section of the moat in front of the city wall was completely encased in these earthen mines.

Because of the large number of mines, in some places there are even several stacked and buried together, resulting in a protruding packet on the ground.

The mines are connected to each other by a wire that is wrapped in solidified ash and separated by paper to give the leads a simple waterproof treatment.

At the left and right ends of the moat, a little further away from the battlefield, there were two guards who had long been hiding there, holding fire in their hands and their eyes fixed on a corner of the city wall.

That's where the signal is supposed to be sent, and what they have to do is to light the lead under their feet with the fire in their hands when the signal appears.

The lead is also hidden in the mud on the inner wall of the moat, about two centimeters above the ice surface, and the lead is placed here to conceal and waterproof.

The two soldiers waited for the battle, and finally, on the section of the city wall in their eyes, a brightly colored red banner appeared, and the bright red was churning in the wind, like a flame hovering in the air.

The two soldiers looked at each other and leaned over to light the pinky fuse.

呲呲呲......

With a burst of green smoke, the fire spread quickly along the bank of the moat, and the fuse burned extremely fast, burning out a distance of more than ten meters in the blink of an eye.

Eugen will not fall twice in the same place, and the same method can be used again and again.

Just as the Saxon soldiers were all gathered on the frozen moat, Eugen ordered the pre-buried fuse to be lit, and at the same time, a row of dozens of guards carrying large barrels appeared on the city wall.

The soldiers tilted the barrel slightly, and the brightly colored oil poured down and flowed onto the ice formed by the moat, gradually covering the entire length of the moat.

The grease on the ice was so smooth that the Saxon soldiers had to be careful when they walked on it, or they would slip and fall to the ground.

Before they could understand Eugen's intentions, the left and right ends of the moat erupted into a violent roar.

Thundered!

The loud sound shook the earth like a thunderbolt, and as the mines exploded one after another, the sound was higher and higher, and sometimes the sound of several mines converged as if to overturn the earth.

Wow! With the explosion of the mines, the fire oil on the ice immediately burst into flames when it came into contact with the open flames, and the flames on both sides rushed towards the center like demons, covering the entire section of the moat in the blink of an eye.

Rumble! Rumble! Rumble!

The explosion continued, starting from the left and right sides of the moat, and spreading towards the middle, and on both sides of the river burst out a grand fireworks, and the flames connected together to form a curtain of fire that penetrated the sky.

Eugen stood on the tall building, the light of the fire reflected in his pupils, like two red elves dancing in it, and the corners of his mouth pulled into an indifferent smile, as if admiring the beauty in front of him.

The explosion blew through Eugen's body, raising his hair back high, sending the smell of burning gunpowder in the air, and he took a deep breath, as if swallowing a flame into his stomach.

The explosion was accompanied by the painful wails of Saxon soldiers, the screams of despair, and the screams of helplessness.

Wrapped in flames, they were like a flock of sheep with no way out, and they could only scurry blindly in place, wrapped in flames, and let out their last roar before dying.

The ladders that had been erected on the city wall fell to the ground one after another, as if to herald the attack of the Saxon soldiers, which was crumbling and crumbling in the flames that would not stop everywhere.

At this time, Simon walked up to Eugen, silently handed him a new musket, and asked in a low voice, "Who to shoot?" ”

True, concise and crisp style, Eugen smiled softly, did not answer, just raised his hand and pointed downward, then put the new musket flat on his face, and began to aim.

Simon did the same, pointing his muskets at the bottom of the city walls.
