On the way back, Su Xiao saw from time to time a small group of Imperial Army patrolling around the black soil fortress. Once he found the tribal army, he immediately fired a firecracker like signal bomb into the sky.

From time to time in the night sky, signal bombs were launched. More than a hundred thousand Imperial troops were divided into several units, and the tribal forces in the nearby areas were cleared up.

Of course, there is a time limit for this kind of cleaning. When night comes, the clearing will be over, and the army will gather in the black soil fortress and guard it.

Not surprisingly, the tribal army will not give up the black soil war zone. After all, it is one of the three major war zones. Moreover, it is not the first time that the tribal army has been defeated.

In this war, the tribal army was very embarrassed. This was not only because of the lack of unity of the tribal army, but also because Carlos personally came to the front line, which made the imperial soldiers move forward.

When Su Xiao followed the army back to the black soil fortress, the black soil wanted to pile up these piles of corpses outside the fortress. These corpses were burned by fire and black smoke rose into the air.

"Get up, be careful. The lasso over there is slower."

"Who saw Martha? Let him be in front of me in five minutes."

"Report that all our sacrificial soldiers have been moved to the black soil fortress. "

the soldiers are busy on the battlefield. Carlos, the head of the army, stands among several officers, who report from time to time.

Su Xiao's troops dispersed after arriving near the black soil fortress, and all the soldiers were free to move.

The recruits climbed up the fortress through the rope ladder. They went to find the clerk in the black soil fortress and wanted to write a letter to their family to tell them that they were still alive.

As for the veterans, they are more willing to send valuable things to their wives and children than letters.

Su Xiao goes to the black earth fortress. He wants to find Nicholas Caesar, the Quartermaster. Unexpectedly, the war achievement shop will be opened soon. At that time, the heads of major adventure groups will also go there. After the war, Su Xiao is not alone in exchanging his meritorious deeds for the holy oak branch.

Fortunately, Su Xiao had a meeting with Nicholas Caesar before, so he was able to walk the way.

Su Xiao climbed up the black soil fortress along the rope ladder. The stone slope outside the fortress has been demolished. That thing has no effect except for facilitating the tribal army to attack the fortress.

Above the walls of the fortress, the ground is wet. Some light red puddles remind people what happened before.

Su Xiao hears the faint smell of blood. Although the corpses on the city wall have been treated and the ground has been cleaned, the smell of blood lasts for a long time.

After inquiring with the soldiers, Sue knew the location of Nicholas Caesar, who had moved back to the black soil fortress with all his possessions.

The stone wall of the whole fortress is about tens of meters wide. The inner side of the fortress wall is hollow, which is used to store materials and live in soldiers. As for the outer side, it is made of obsidian. This side is often attacked by the tribal side, which is not solid.

Su Xiao enters the inner wall of the fortress, which is similar to a large war fortress. There are 16 floors in total. Each floor has a corridor, which runs through the whole floor horizontally, making it easy to walk.

From the 16th floor to the 6th floor, it is used for soldiers to live in. It is divided into a large shop of thousands of square meters. From the 5th floor to the 4th floor, it is used for officers to live in. Here, it is divided into a small compartment. The higher the position, the better the living conditions. From the 3rd floor to the 1st floor, it is used to store materials.

Su Xiao walked into the interior of the fortress, a strong smell of gunpowder came, and large pieces of black gravel scattered in the corridor. This is a masterpiece of the tribal side. They wanted to blow up the black earth fortress before, of course, from the hollow side.

There is a torch on the wall of the corridor of the fortress. The light is flickering and the fortress is cold and wet.

According to the information, Nicholas Caesar lived on the fourth floor, where the senior officers could live.

Su Xiaogang walked to the entrance on the 4th floor and found several soldiers standing in front of the entrance.

"Please show me the officer's certificate."

The soldiers stood upright and serious.

"I'm the team Changbai night. I haven't proved it yet. I'm an officer who was appointed in wartime. "

Su Xiao has nothing to prove his identity. However, he doesn't need identity certification at all. Just after the war, there are many newly appointed officers. These officers have no official certification. As for pretending to be officers, ordinary people won't do that, which is a capital crime.

Several soldiers looked at each other and hesitated.

"I'm sorry, sir. You can't enter here for the time being without the officer's certificate."

A soldier came up to him and said in a low voice, "my Lord, I can't help you, don't embarrass me."

The soldier's words were already imploring.

"That's a good way."

Su Xiao roughly guessed what was going on. Needless to say, these soldiers were planted here by "intentional people". Now that the war in the black soil fortress is just over, the officers are very busy and have no time to come back here. There is only one kind of people who will come here at this time, that is, the contractors who want to exchange their achievements for goods.

Su Xiao is a war achievement shop opened only after he got the position of officer. So are the heads of the adventure regiment. The leader of the adventure regiment can recruit 200 subordinates, which is actually for the adventure regiment. The leader of the adventure regiment will recruit subordinates as subordinates, so that he can help subordinates to open the war achievement shop. Only when the war achievement shop is opened, the war achievement will be displayed.

Now the soldiers who block Su Xiao are likely to be recruited by the leaders to prevent other contractors from seeing Nicholas Caesar.

Even if we can't block everyone or some of them, the military discipline is strict in wartime, and most of the contractors dare not make trouble.

Thinking of this, Su Xiao pushed away the soldiers in front of him and walked straight ahead.

"Wait."

These soldiers didn't shout "stop" or "kill if you dare to get close", but subconsciously shouted "wait". This made Su Xiao more certain that these soldiers were paper tigers.

Su Xiao stepped forward and looked at the soldiers. Now it's them who should be guilty.

"This adult, villain "

a slightly older soldier stepped forward.

"More nonsense, kill you."

In the face of this deliberate obstruction, Su Xiao will not be polite.

“……”

Several soldiers step back. They have a feeling that if they stop Su Xiao again, they will really die. If they die now, they will die in vain, and they will be charged after death.

Su Xiao walked into the corridor on the 4th floor of the fortress. From a distance, he saw a dozen people standing in the corridor, as if waiting for something.

After seeing these people, Su Xiao recognized them as contractors, because there were "Acquaintances", the two brothers and sisters who had met outside the Quartermaster's tent before. Su Xiao sold the "Oxbow Lord's armband" to his younger brother.

A dozen contractors all looked at Su Xiao. The dozen were divided into four groups, which basically represented that there were four adventure groups left in the black soil war zone.
