Although the mecha team of the wh city police force has powerful weapons such as sentinel missiles, they dare not use them for fear of blowing up the tunnel.

This made Ao even more unscrupulous, relying on the high durability and high armor of the aircraft to run rampant.

There is no more room for the Sentinel to hide in the tunnel. If it is stabbed by the knight's spear, it will be scrapped.

The pilot in charge was anxious in his eyes, but for a while he didn't have a good way to deal with it.

After a minute, I think it's almost done.

Ao didn't show any interest in fighting either. He held up his spear shield and stepped back a few steps. His missile port was fully opened, and he aimed at the top of the tunnel and fired the four prepared blasting missiles.

This kind of missile has a particularly obvious effect on buildings and is generally used when attacking fortresses.

After the connection explosion, the upper wall pillars were damaged and nearly ten meters collapsed. Large pieces of rubble fell from above. Occasionally, a Sentinel was hit.

Before the chaos ended, Ao fired two more smoke missiles, and the tunnel was suddenly filled with a large amount of red smoke.

After doing this, Ao turned back and got into the entrance of the underground passage.

It would take a few minutes for the red smoke to completely dissipate, long enough for him to run far away.

"Damn it! I can't see anything!"

"Lost target...repeat, lost target..."

The Sentinel did not have an infrared module and relied on the naked eye to detect enemies, causing the pilots to fall into chaos.

"What's going on?" The Sentinel fighter at the other end of the tunnel shouted on the public channel. He had been in position for a long time.

"Everyone be quiet! Be alert to your surroundings!" the chariot driver roared, and then calmly explained to the sentinel fighter, "There is a small problem, we are solving it, they may rush to you at any time, be sure to stay on guard

Nice tunnel entrance!”

"Understood, I have locked the entrance of the tunnel. More mecha teams are coming. The blockade will be completed soon. Please pay attention."

As the sound of the Sentinel fighter jets stopped, the channel immediately became quiet.

At this time, the mecha team in the tunnel also readjusted.

"First team, take cover, second team, search their positions." The commander issued the order again.

"Understood." A group of mechas began to move slowly along the tunnel in a defensive formation.

The other team of mechas stayed behind with weapons in hand, ready to join the battlefield at any time.

"No enemies were found on the left..."

"There is no trace of the enemy in the central part, only an empty escort vehicle..."

"There are no enemies on the right, repeat..."

They were afraid, they couldn't see anything around them, and Chen Han and others were silent, so they might be hiding somewhere.

Two minutes later, the mecha team, which was advancing at a snail's pace, finally reached the entrance of the underground passage, and the smoke began to dissipate.

"Report, I found that the underground entrance was forcibly destroyed. Do you want to go in and take a look?"

The pilot in charge was frightened by this news. The width and height of the entrance to the underground passage seemed to be just enough to accommodate the mecha.

Thinking of this, he immediately opened the virtual screen, called up the structural diagram of the tunnel's interior, and took a closer look.

When he discovered that the right side of the tunnel was connected to an underground waterway, his face suddenly turned pale and he slapped the control panel: "Damn it! They may have left the tunnel and entered the underground waterway!"

"ah?"

"What?"

The surprised voices of several Sentinel pilots sounded on the public channel.

"Stop screaming and chase after me!" the pilot in the tank roared.

If the enemy escapes in this way, their people will suffer a big loss.

A few seconds later, the leading sentinel commander led two teams of sentinels into the hole.

But soon they encountered new troubles. The underground waterways were crisscrossed and chaotic, and could lead to any part of the city.

Without accurate tracking methods, trying to find someone inside is like looking for a needle in a haystack.

At the beginning, they could also use their experience to search for some clues and follow closely behind.

But as they went deeper, they got lost without paying attention, and even the waterway map was useless.

In desperation, they could only report the current situation truthfully to their superiors.

After receiving the news, the senior police officers of Wh City were shocked.

They have been responding to the robbery with all their strength since the robbery occurred. After all, it was the Ao Group involved.

But they didn't expect that things would develop like this and that they would be out of control.

In order to regain control of the situation, they directly dropped hundreds of mechanical dogs into the underground waterways and used remote control to replace manual searches.

At the same time, hundreds of mecha teams were dispatched to guard the exits of most underground waterways.

As long as the mechanical dog finds any clues below, the mecha team above can immediately provide support.

With the dragnet being laid out, the top brass of the security force breathed a sigh of relief.

They believe that it is only a matter of time before they find the robbers and others, and then they will be able to give an explanation to the Aoshi Group...

After Ao got rid of the tracking of the mecha team, he quickly found Chen Han and others.

"Brother A'ao, we are here." Ning Bai shook her twin ponytails and waved with a smile.

The blood on her face has dried, and there is no trace of the ferocity she had just now.

"Be quiet, there is an echo here..." Chen Han hit Ning Bai on the head with the muzzle of his sniper rifle.

This made Ning Bai purse his lips, as if he was dissatisfied with Chen Han's actions, but for a while he didn't dare to talk back...

Ao quickly came to Chen Han: "Boss, I threw them away. I don't think anyone will catch up within ten minutes. Where is our goods?"

"Yeah." Chen Han nodded and shook the box in his hand, "It's all in here."

"Why are there two? Do you want to open it and check? See if there is a tracker or anything inside." Ao looked at the box in Miaoying's hand again.

"It's encrypted and can't be opened." Chen Han shook his head.

He had tried it just now while waiting for Ao, but the box required a password.

"The eldest sister said that if the box is specially encrypted, it may be destroyed automatically if it is opened by force. We have to bring the battleship back first." Miaoying mentioned.

After these days of getting along, they all learned to call Maki Qianye the eldest sister.

"It's actually encrypted. It's interesting. Let's evacuate quickly and leave this crappy place as soon as possible." Ao shook the knight's spear in his hand.

"Well, speed up." Chen Han used his body to project a virtual map.

In addition to the zigzag routes inside, there is also a red marking point, showing the interstellar airport in wh city, fifteen kilometers away from here.

Their fighter planes are parked there, and this underground waterway leads directly to the interstellar airport, which is the best escape route.

As long as they get on the fighter plane, they can leave the planet, return to the battleship, and successfully complete the assessment mission.
