Rob's thoughts followed the convoy from afar. After more than ten minutes, the convoy entered the bush.

The largest bush near this place is the rift valley where Rob was entered, leading to the rift cave. This convoy is going to come into the underground.

This discovery cheered Rob.

If it is on the flat ground, the only way to defeat this team is to ambush and attack. Rob's current number of components is still too small, so it is difficult to attack this team.

Each of these two hundred human guards has the strength of a level 3 or above swordsman, and is also well-trained and has a strong frontal attack, even if they are five war gods of war structures, they may not be able to defeat the opponent. Even if they are taken, the losses will inevitably be heavy.

But if this team enters the ground, there are many tactics to use.

Some time ago, in order to find a suitable place to build a stronghold, Rob almost moved the entire underground. He released the detection structure to survey the general terrain. Even those native-born and wise rats were not as familiar with the underground situation as he is now.

After confirming that the other party was about to enter the ground, Rob immediately retreated from Leng Gang's God of War. Leng Gang had ten minutes left to use. If you want to attack the other party, it is very important to understand the other party's movements in a timely manner, so Rob decided to leave the remaining usage time until necessary before using it.

Putting all the components in place, Rob rode on Jirasha and ran out of the hole. He had to arrange the trap before the other party reached his position.

As soon as he walked to the iron gate, a small black shadow rushed out of the cave above. Without taking the stairs, he jumped down from the three-story cave that was thirty meters high. In the air, the figure that shrank into a ball suddenly striking, and the fall momentum disappeared. Then the whole figure flipped and fell skillfully on Jilasha's back.

The little figure who fell on Jilasha's back was half-squatting, staring at Rob stubbornly with his lips pursed. The only one kitten girl who dared to stare at Rob like this in the entire Tiejian Castle was naturally the only kitten girl. When Rob went to the Ratman's Ancestral Tomb some time ago, he was afraid that the breath of death would erode her, so he refused to take her there. Unexpectedly, he stayed in the Ancestral Tomb for more than a month. After returning, he felt that the abandoned kitten girl had never said a word to Rob until now.

But now when Rob wanted to go out again, she immediately followed.

Rob was not going to the kind of place that had a great impact on creatures this time. After glanced at the kitten girl, he ignored her and did not drive her down.

Rush, before the rest of the people could react, Rob had already left Tiejian Fort and ran towards the entrance of the cave.

The ground shape here is already very familiar with. When he was detecting the structure and exploring the terrain, he deliberately remembered the important route. What he was going to now is a must-pass way to enter the underground from outside.

The caves in the underground cave are well connected and are almost connected, but if you want to pass the carriage, there are very few routes to choose. No matter which one you choose, it will inevitably lead to the bank of the underground river in the end.

One of the passages is attacked by years of flowing water, forming a smooth slope. When people stand on the slope, they can slide smoothly to the bottom of the slope. This is the only passage nearby where carriages can be passed. If the convoy is about to come down, this slope is a must.

The first time Rob arrived at the slope, he released the fifth God of War, including No. 7. At the same time, he released the Leng Gang God of War, switched in as fast as possible, and then extended his soul to the ground.

The other party was a heavy-duty convoy, and each carriage was full, so the speed was naturally not enough. At this moment, it had just entered the range of the rift and was walking towards the bottom of the valley. It would take some time before it could enter the ground. It was very abundant when it was left for Rob.

For safety reasons, Rob took out a special detection construct. This construct does not have much ability. Its only function is to carry the soul, let Rob transfer his mind to it and observe the situation through it.

Rob only made two such a structure, each of which is the size of a fist. This is also the smallest size that the soul structure can be reduced. If it is small, it will not be able to carry the soul fire.

The six-legged soul detection structure quickly ran towards the entrance, and after being tied to the opponent's team, then conducting reconnaissance at any time.

Then the war god components such as Jirasha and No. 7 began to quickly arrange traps.

...

Angateson was very energetic, urging the team forward while carefully sensing the situation around him.

When he was on the ground before, he felt vaguely being spied. Although he didn't find anything in the end, he became alert. In fact, an elite team like them was sent to escort supplies, and what he wanted was a foolproof one. Unless he sent a large army to cooperate with the masters to encircle and suppress, ordinary thieves would die more or less.

But Angateson was not careful because the supplies escorted this time were too expensive. Twenty cars of magic crystals of each system were of great value, but they were consumables after all, and it was no big deal to lose them. But if the magic crystal cannon was lost, their entire team might have to be buried with him.

The magic crystal cannon is an invincible weapon for siege. It is a highly regulated weapon in any country. If someone finds that it owns even a component, it will be treated as a crime of treason.

And the cannon itself is extremely precious.

The purpose of spending so much manpower and material resources to transport the cannons here is to knock on the gate of Black Iron City.

As the gateway to the northwest land, Black Iron City was built at the beginning of its construction towards the standard of a war fortress that never falls. The inside of the city wall is a cast steel inner core, and the outside is surrounded by large stones that have been treated with anti-demonic treatment. There is also a circle of defensive magic towers inside the city wall. Unless it is a forbidden spell cast by the great magician, once the defense is opened, there is no external attack to break the defense of Black Iron City except for the magic crystal cannon.

In order to win the Black Iron City in one fell swoop, the organization spent a lot of manpower and material resources to transport the magic crystal cannon here, just to be foolproof. Even if it is blocked by conventional siege, there is a final means to break the city.

Therefore, this magic crystal cannon is crucial to the entire organization's plan.

Angateson was ordered to transport the cannon, and only he and the other two in charge knew what was loaded inside. Along the way, they didn't even walk the main road, all of them came from small roads in the mountains and waded through the mountains and rivers.
