After dinner, the soldiers chatted for a while, then they all went back to their tents and closed their eyes to rest.

It is the soul of the whole Yongfeng leading army to be relaxed, strict in discipline, and forbidden. It is also what every Yongfeng leading soldier must do.

As time went by, the two camps gradually fell into silence.

Only a team of patrolling guards were carefully guarding against the surrounding movement.

Although it is rare to attack the camp late at night, it is still common for warriors to sneak into the camp and cause damage.

At one o'clock in the night, the soldiers in Yongfeng's defense line had already woken up from their sleep.

Quietly carrying a huge piece of wood and sandbags, the fort gate will fill several trenches.

And then they retreated back into the line.

The adventurers who had been in the back of the fort also found the abnormality. They all looked at the top of the fort curiously.

Because above the fortress there were bursts of murmuring birds.

After a while, they saw a large group of carrier pigeons flying from the top of the fort. At this time, they seemed to be carrying a heavy weight on their claws.

However, these carrier pigeons are flying very smoothly, flying fast into the sky and disappearing into the night.

At Mingguang army station, the soldiers were sleeping in the barracks.

For them, the strength of this battle is too different. As long as they have enough spirit and get up in the morning and crush them directly, they can successfully attack the defense line and get a reward.

At this time, the sentinel soldiers are also around the campfire to bake the fire, look relaxed, talking in a low voice.

At this time, none of them realized that there was a dark cloud floating slowly in the sky above their heads, and the dark clouds stopped moving just above the Mingguang army station.

If you look closely, you will see what dark clouds are there in the sky? But a gray and black carrier pigeon, is constantly fluttering its wings in the sky.

There were regular and buzzing whistling sounds, but because the distance was too high, the Mingguang army below could not hear anything.

What carrier pigeons bring is not a love letter or a care, but a grenade wrapped in black iron, filled with a lot of gunpowder and scrap iron.

When all the homing pigeons have reached the predetermined position, Xiaozhi makes a burst of cooing in the middle.

"Goo Goo!..."

Then Xiaozhi then dive down and go, at the same time the grenade in his claw also brushes down from the sky.

The trigger device of these grenades uses impact. As long as the impact is strong enough, the explosive will be ignited and explode.

At such a high altitude, it is obviously more practical to use this trigger mode than to use a fuze.

However, this also increases the difficulty of transportation, we must be careful, or it may explode on the way.

This batch of hand grenades were produced temporarily. These are the only ones. If they are not, the battle plan of the whole defense line will be affected.

It can be said that soldiers carrying grenades are more nervous than those on the front line.

With the whistling sound, the grenade fell quickly.

The ordinary soldiers below still do not know, death has opened his hands to them, exposed fangs.

However, as the distance approached, some high-level warriors found something unusual. They seemed to hear the whistling sound in the air, and quickly walked out of the camp and looked into the sky.
