There is also a Revenge-level aid sentry vehicle and a Night-level raid sentry aircraft.

The aid-type sentry fighting vehicle is green all over, three meters long, two meters high, four tons, and has six and a half meters high wheels. It looks like a green iron box from a distance.

There is a tower-shaped device that is constantly rotating at the top of the vehicle body, which can collect information on the battlefield for summary.

The only attack weapon is four single-hole energy cannons, distributed in four corners, and its power is relatively average.

The raid sentry fighter is a bit like a conventional military helicopter, with huge propellers above it and is quite fast.

The weapons are two integrated machine guns, one particle cannon, and a sentry missile launching slot, which has a relatively powerful firepower output.

"There are too many people, stop fighting, withdraw!" Chen Han shouted.

They have been wasting too much time here, and there is no point in fighting.

Miaoying was also very decisive and directly opened the missile launch port, shot out six incendiary rounds, and sealed the road with flames.

At the same time, the fire pulse also hits the magnetic energy vehicle in the distance, causing an explosion and creating greater chaos.

Chen Han even trotted and climbed onto the roof of the escort truck driven by Ning Bai and lay down, asking the escort truck to take him to retreat.

Miaoying had no place to lie down, so she could only get into the carriage and look at the box.

Since the road behind has been completely blocked, there are no cars in front of the entire right lane, allowing Ningbai to accelerate with all his might.

"Intercept them!" The pilot in the aid chariot issued an emergency command.

The next second, the fighter jets in the air called in two sentry missiles and tried to block the route of the escort van.

Ning Bai didn't see the missile at the first time, but instead pointed to the giant screens of the tall buildings on both sides, with a smile on his bloody face: "Chen Han, Chen Han, look, we are on the news!"

It turned out that the scrolling screens that were originally advertisements turned into scenes of Chen Han and others robbing the city's avenue.

It was probably an emergency interjection, after all, this is too big.

"Little ancestor, I beg you to stop watching and drive well!" Chen Han slapped the carriage and shouted.

At the same time, the left arm moves continuously, and it turns into a storm spiral tube, sweeping hard at the missile that drags the tail flame a hundred meters away.

Under the blockade of hundreds of energy bombs, two sentry missiles exploded directly in the air.

This is also Chen Han's recent discovery of the method of dealing with missiles, which can use dense firepower to detonate the missile in advance.

But it is limited to one or two missiles, and it is still unbearable to deal with too many.

This scene shocked the guards collectively. As pilots, they knew that this operation required an extremely high hit rate.

The pedestrians watching the fun in the distance were even more stunned. Chen Han, the most threatening missile, responded to it like playing, before, now.

But this did not allow them to escape the pursuit, and the fighter planes above quickly fired two more sentinel missiles.

This time Chen Han could not continue to intercept. The storm spiral tube needed to be charged, indicating that the force field chip is still cooling. If you use it forcibly, it will burn directly. You can only shoot the carriage: "It's coming again! Hide!"

"Damn Chen Han! The missile is so fast, how can I hide..."

Ning Bai cursed, but her movements did not stop at all. She quickly twisted the direction ball and controlled the escort truck to swing continuously.

With left and right movements, two sentry missiles exploded three meters behind the escort truck and two meters ahead, respectively, and two large pits were blasted out.

As a shock wave passed, the moving escort truck almost lost its balance. If Chen Han hadn't grasped it firmly, he would have fallen.

But Ningbai did not slow down because of this, but instead increased the speed of the escort truck to the maximum and rushed forward for more than 30 meters.

But the sentry fighter was faster and followed in an instant. The double machine gun and particle cannon aimed at the escort van and Chen Han and swept it.

The escort truck has a good protection ability and can withstand it for the time being, and the cockpit is fine.

However, many weapons in this posture have restrictions on the Damage number and cannot fight back. Chen Han can only be beaten passively.

Not to mention the wonderful shadow in the car, she didn't even have the vision of the fighter plane above.

Looking at the rearview mirror and feeling the "bang bang" sound of bullets hitting the car, Ning Bai's face turned red with anxiety: "Chen Han, suppress it! If there are two more missiles, I can't dodge it!"

Her right hand was just scratched by broken glass fragments and was bleeding, which would greatly reduce her control ability.

"Continue to open! Just enter the tunnel!" At this time, Chen Han's storm spiral tube was also charged, and he lifted it to aim at the sentinel fighter plane and swept it hard, suppressing it.

The sentry fighter jet that dared not take it hard can only climb tactically and make emergency avoidance, and cannot continue to fire missiles.

This gave Ning Bai a chance to breathe, and drove the escort car to run a kilometer, getting closer and closer to the tunnel.

"Be sure to intercept them! You can't let the escort van enter the tunnel!" The sentry chariot chasing two hundred meters behind issued an emergency order again.

Because the tunnel ahead is two thousand meters long and has a height limit of six meters, and the fighter jets cannot enter, it will be very troublesome to track it.

In addition, the tunnel is relatively narrow and there are high-speed magnetic energy vehicle tracks at the top. If a fight occurs inside, it is easy to cause a collapse accident, which will be troublesome at that time.

"Understand! I will intercept with all my might!"

The sentry fighter jets that received the order no longer evade and continued to suppress them at the risk of being hit, and the only two sentry missiles remaining were ready.

At the critical moment, he had no time to lock the missile, unlocked the missile, aimed at the fifty meters in front of the tunnel entrance, and prepared to delay the time.

"Hide!" Chen Han slapped the carriage and reminded Ning Bai.

Ningbai didn't say anything and kept paying attention to the high point.

After calculating the time, she suddenly braked and stopped seventy meters in front of the tunnel entrance.

She was not sure to rush into the tunnel before the missile landed, so she could only stop in advance.

Chen Han, who was not steadily caught, fell down from the top of the car and rolled several times.

Ningbai's choice was extremely correct. The escort truck stopped for a second and the missile exploded in front of him.

"Damn..." Chen Han, a little confused, quickly got up from the ground. Before he could say hello, Ningbai started the escort truck again.

Seeing this, Chen Han could only quickly turn up and disappear on the city road together.

"Fuck! They went in, I lost my target! Repeat..." The sentry fighter plane hovered above the tunnel entrance and reported, and there were also some sounds that seemed to be slapping the control plate with a slap...

"I received it, and our department will chase you next. You will fly to the other end of the tunnel immediately. This time, be sure to block them in the tunnel!"

New orders are issued by the commanding aid chariot.

At the same time, turn on the tracking radar on the top of the tank to scan the tunnel and capture the escort van signal until a fast moving red dot appears on the virtual screen.

"Locked up, all the mecha teams follow me!" The chariot pilot sneered, drove the chariot and was about to rush into the tunnel, with two other mecha teams following closely.

The fighter planes above quickly flew to the end of the tunnel, opened all the muzzles, and waited for the escort truck to come out, forming a momentum of siege on both sides.

As the aid chariot penetrated deeper, the back of the escort chariot was soon seen in the tunnel, and the speed was significantly slower.

Just as the chariot driver wanted to launch a tentative attack, the escort truck suddenly stopped.

Immediately afterwards, Ao drove the Fal Knight Ag and appeared from the side, with his left hand spear and his right hand spear.

He has been waiting here for a while, just to be responsible for cutting off the rear when Chen Han and others retreat.

Before the chariot driver could react, Aao raised his shield to block the front.

As the front of the car collided violently with the spear and the shield, the sentry chariot was forced to stop.

"Note! There is a third mecha! They have accomplices!" The chariot pilot shouted and began to adjust the angle of the muzzle above and fired continuously.

However, these energy bombs were not very effective on the gun cavalry and shield. Instead, Aao shot a close-up gun and slid the chariot backward for nearly one meter and directly turned off the fire.

There were cracks in the bulletproof glass in front. If it weren't for the sufficient protection, the pilot inside would have to be out of the way.

Fortunately, the two mecha groups behind arrived at this time, and the firepower of the shotgun in their hands almost formed a barrage in the narrow tunnel.

"Kill him quickly! There is something wrong with my engine and it takes time to restart the system. Pay attention to the firepower intensity and don't blow up the tunnel..." The pilot in the chariot was operating quickly while commanding.

The Sentinels immediately surrounded the chariots to protect the fire, and the shotgun in their hands became even more fierce.

The escort truck was affected by a lot of ammunition, and the damage became even worse, and the rearview mirror was broken.

"Boss, you go first!" Ao held up the Knight Shield and directly activated the defense matrix chip.

The next second, a blue energy wall similar to a curtain expanded in front of Aao, blocking most of the firepower in the front.

"Received." Chen Han killed a sniper bullet with an outward sentry and patted the carriage.

Ningbai kicked the half-baked door open, held her small schoolbag and jumped off, leaned against the tunnel on the right to a hole that was more than three meters high and two meters wide.

The underground waterway directly leads to WH City. It was the escape route they found after studying for a long time. Aao hid inside for a night, and there was also an alloy door that had just been unloaded on the ground.

"Go down quickly." Chen Han chased Ning Bai with his gun, and each carried an escort box.

"Oh~" Ning Bai dragged the long tail sound, looked at the dark underground waterway.

Then I took out a skateboard from my schoolbag and slid down the stairs into the underground waterway.

"We're going down, you have to retreat in a minute." Chen Han shouted in the channel and walked into the underground water channel without looking back.

Miaoying followed closely behind, and before going down, she still shot out four high-explosive missiles to support Aao.

Chen Han and others had no worries about leaving Aao.

Immediately cancel the defense matrix that was still consuming mecha energy, and wield the Knight Spear to pierce a sentry mecha that happened to come.

At the same time, the electronic pulses of the shoulder close-to-proof gun and the head are constantly bombarding the nearest body.

Although the mecha team of the WH City Guard has a powerful weapon such as sentinel missiles, they are afraid of blowing up the tunnel and dare not use it at all.
