Although the goblins have not invented a program to carry out automatic strikes like the base, many goblins of old and weak women and children are able to use these things.

And there are many old, weak, women and children among the goblins, and with the natural talent of goblins to use firearms, they are distributed everywhere in this steel city to guard work.

And after Colonel Xi and the others came here, they began to constantly detect the surrounding guards, and if they wanted to blend in unknowingly, they must find a blind corner route among these many goblin guards, otherwise they could only attack by force.

After a few days of observation and analysis, Colonel Xi found a blind route, in the absence of a comprehensive scan like a computer of the base, relying on this kind of defense with manpower as a guard, it is a time when everyone is negligent.

And this omission has become a habit in the past thousand years, and the time of every shift change has been fixed, although countless groups of people have been changed in a thousand years, but the habits of this group of people have been perfectly scanned by the scanning system and analyzed by Colonel Xi.

"Tonight we enter this dwarf and goblin underground city, we only have one chance, failure can only leave quickly, so everyone be prepared to fight, this time I will not allow failure, and after completing this mission, dwarves and goblins will not have the strength to attack humans." Colonel Xi also said with a solemn face.

Originally, Colonel Xi was arranged here to prepare to conquer the base camp of this group of goblin dwarves, so that the dwarves and goblin armies in the Luo Tian Empire had no source of back, and there were definitely a lot of metal resources in the inventory of goblin dwarves, and they could steal all these resources once and for all.

Unexpectedly, Colonel Xi, who was about to act, found that the dwarves and goblins had returned to the base camp from the Luo Tian Empire, which delayed the original plan.

And the return of the goblin dwarves also strengthened the guards, so that the tide colonel who had been preparing for many days fell short, and then delayed a lot of time again to find the blind corner route to enter.

When night fell, the goblin guards who had just changed their guard were still guarding the place as usual, but as usual, there was no movement at all. began to slouch.

This dungeon of goblins and dwarves has not been visited for thousands of years, let alone the dungeon, even in the outer mountains, no one has passed, and the comfort of a thousand years has also made the goblin guards on guard.

"Now, start diving in. "Following Colonel Xi's words, under the leadership of Colonel Xi, many rocket angel guards followed one after another.

When he came to the first dead end, Colonel Xi also saw the opportunity, and then stretched out four fingers to gesture at the back, and then rushed in. Quickly came to a hidden location.

And in the rear of Colonel Xi, 4 Rocket Angel guards also chased after him, followed Colonel Xi into this hidden position and hidden.

When Colonel Xi and the others hid in, the original troops also stayed in the position just now and did not move, but waited for the goblins to continue to sneak in when they shifted their targets again.

After the team was scattered, Colonel Xi also took the lead in entering the entrance of the dungeon with 2 Rocket Angel guards.

At this time, the guards at the entrance at night were even more lazy, and there was no movement outside, although the guards were not asleep, they were almost in a state of confusion or laziness chatting with their companions.

Colonel Xi gestured to the two guards behind him, and then quickly sneaked towards another hidden position. When some of the Rocket Angels arrived, everyone was quite close to the group of guards.

Colonel Xi shook a few gestures at the hidden position, and several of the rocket angels in the hidden position pointed their delicate small pistols at the heart of the goblins guarding the entrance.

And under the instructions of Colonel Shio, everyone fired at the same time.

Burst~~

A slight sound. Even the goblins didn't hear any sound, and the sound of the bullets was canceled out by the silencer, but the bullets hit the guards in the heart with undiminished force.

Boom~~

When a goblin guard falls to the ground. Before the other goblin guards could reach the end, they were held by the rocket angels who rushed over, and then placed in the designated position under the orders of Colonel Xi.

Placed in this position of theirs, there was nothing unusual at all from a distance. Their death cannot be seen until they come closer.

And Colonel Xi also left a few Rocket Angel guards here to watch this entrance, and assassinate them once someone arrived.

Although the Rocket Angel guards are not as proficient in assassination as secret spies such as Caton, it is still possible to kill unsuspecting goblins and dwarves, and their hiding position is enough to make it difficult for goblins and dwarves to detect, and when they get close to these corpses, the Rocket Angel guards can lock them in the best position to shoot.

Colonel Xi quickly entered the underground passage with the rest of the rocket angels, looking at the location of the dungeon in the underground passage, looking at the unobstructed position at the staircase, his eyes turned to a remote location and continued to observe the terrain.

"Go here. ”

Colonel Xi let out a low sigh, and then took out the equipment on his body and climbed down from the corner of a cliff wall, with such a climbing speed, it was very hidden to go down from this entrance, but it was extremely exhausting.

When Colonel Xi and the others climbed down, Colonel Xi was a little moved and his body was slightly warm, and this physical work could already be done in a state of warm-up.

And just after the warm-up, Colonel Xi watched as the Rocket Angel guards came down, and then began to scan the nearby terrain through a small positioning map.

With the scanning of the small positioning map, Colonel Xi quickly made various calculations in his mind, and when he calculated the route of travel, he quickly blended into the dungeon with all the rocket angel guards.

"Who. I don't know if it's night," a goblin got up in a daze and opened the door, facing the guy who didn't know which guy was still running to disturb his rest at night, and he was going to ask for a good look.

And when the door opened, Colonel Xi's powerful hand directly pushed the goblin in, and at the same time sealed his mouth with the other hand.

Before the goblin could react, a huge force came from his neck, and before he could make any sound, he was torn off by Colonel Xi.

After hiding the goblin corpse under the bed, Colonel Xi watched as the rocket angels in the room were on guard for 4 weeks.

And Colonel Xi also kept pressing various buttons on the small positioning map, and began to scan the arming situation in this underground city.

With the location of this room and enough to scan most of the dungeons, even if you can't achieve what you want.

And under the continuous scanning of Colonel Xi, he finally found a corner of the target location, and looked at the obvious picture on the small positioning map, Colonel Xi also smiled.

Now that the target has been found, Colonel Xi has also begun to look for a safe route, and this is also a crucial moment, as long as this target is in hand, even if the other party finds out, he can quickly fly away from here through the Iron Queen and the Rocket Angel Mecha, and without these target materials, it will not be so easy for goblins and dwarves to start a war now.

It will take a long time for them to continue to excavate more metal materials, and in this time, the Orc Wasteland may have been defeated by the Mysterious Marshal and the Dragon Admiral.

At that time, under the upgrade of the base, the alien race may no longer have the power to fight, and Colonel Xi is quite confident in the large-scale military strength improvement after the upgrade of the base, and at this time, Colonel Xi also let go of any distractions and began to make plans.

With the continuous scanning of the small positioning map, it took Colonel Xi a full 2 hours to figure out the infiltration route this time, and when Colonel Xi confirmed that it was correct, he began to gather all the rocket angel guards around him.

"Now we are divided into 5 teams, led by me and the 4 of you, from these 5 routes one by one to these positions, and then quickly attack, I will quickly take away the resources inside, and then after I open the Iron Queen, everyone will quickly evacuate. ”

After Colonel Xi explained the plan to the Rocket Angel guards, everyone began to act, with the scanning system of a small positioning map, Colonel Xi and the others found the loophole well and rushed to the designated location to hide.

While watching the inventory guards doze off, Colonel Xi also lurked over with a few rocket angel guards, killed these goblin guards who had no ability in a few clicks, and then dragged them to the corner to hide.

"Quickly, quickly take all these minerals. After Colonel Xi took out the weapon wrist given by Wang Chang, he quickly collected all these minerals, and the other rocket angels also carried these weapon wrists.

After the base reached level 7, the weapon center was also able to decipher Wang Chang's weapon wrist and imitate the manufacturing, and when Colonel Xi and the others plundered the entire warehouse, they began to quickly evacuate.

Sneaking out before anyone is detected at this point, because the mission is already halfway completed, and if you can sneak out without being detected, then you won't have to face the attacks of many goblins and dwarves.

After Colonel Xi and the others left this empty mineral warehouse, they walked towards the entrance outside the dungeon, and at this time, the whole city was silent, and many goblins and dwarves were resting, not knowing that their supplies had been stolen. (To be continued......)
