Doomsday: Unlimited Upgrade Mobile City

400 yards speed, how to chase?

Is the back of Donglongcheng's butt a super rocket thruster?

What kind of ghost technology is that?

Yan Xue stared at him with wide eyes: "He is so fast, is he not afraid of the boiler exploding? Aren't he afraid that the propeller will melt?"

Inside the door to see the door, the layman to watch the fun.

The steel used in the propeller must be resistant to high temperature, and the smelting technology of steel varies from city to city.

The melting point of ordinary steel is 1538.

Above this temperature, steel will melt and deform, becoming molten iron.

The special steel used for rocket propulsion needs to withstand the high temperature of three or four thousand degrees.

The production process of special steel is extremely complex, but it cannot be produced in any city. It is only possible to produce it through cooperation between large groups and alliances.

Special steel is much more expensive than gold!

"City Lord, the other party may be overloaded and want to get rid of us. Let's also start a full-speed pursuit. When the other party's overload is over, we can catch up."

The old adjutant gritted his teeth: "I don't believe it! He uses high temperature-resistant special steel in Donglong City!"

Yan Xue raised his hand: "Go ahead at full speed and drive to 240 yards for me!"

The people around picked up the walkie-talkie: "Turn on the power to the maximum!"

"Inject coolant to make sure the boiler doesn't overload and explode!"

"After the coolant is injected, the overload can be maintained for half an hour!"

The entire Donghai City was busy.

Yan Xue ordered again: "Fortress City also overloaded me! Full speed ahead!"

The 8 fortress cities have pursued at a high speed of 280 yards, but compared with the 400 yards of Donglong City, it is almost every day.

The two sides chased each other, but they couldn't even catch up with the exhaust of Donglong City.

Suddenly, the tail flame of Donglong City in front began to weaken, not as bright as before.

"City Lord! Donglong City has slowed down to 250 yards!"

Yan Xue was refreshed when he heard this: "Okay, Donglong City can no longer be overloaded, and our fortress city can catch up with him immediately."

Yan Xue clenched the rudder excitedly at the thought of being able to grab Wang Cheng, the damn little white face.

Suddenly, Donglong City in front turned the boat and stopped running! Instead, they rushed towards the eight fortress cities.

"City Lord, Donglong City plans to engage in close combat with our fortress city!"

"Oh? Then he is courting death!"

No need for the main city to take action, eight fortress cities can take down Donglong City.

The old adjutant smiled and said, "We can have a drink to celebrate. Donglong City knows that we can't escape, and we plan to make a fish and a net."

However, at this moment, a sudden change suddenly appeared!

Donglong City accelerated and rushed towards the eight fortress cities, as if they were completely dead.

"This Wang Cheng is too bad, he actually let his mobile city besieged."

Donglongcheng rushed to the eight fortresses, courting death!

Yan Xue picked up the walkie-talkie: "Just destroy the power system of Donglong City!"

Stop the fight in Donglongcheng, Wang Cheng will definitely surrender without a fight.

At that time, this little handsome guy raised his hand and surrendered, thinking about Yan Xue, he was still a little excited.

However, it was all too taken for granted.

When Wang Cheng rushed into the encirclement and was surrounded by eight fortress cities.

He opened his mouth and said, "Su Mei, you control the main gun to blast all the opponent's thrusters!"

"learn!"

Su Mei didn't care about anything, the mad city lord led them into the encirclement.

The hull of Donglongcheng was opened, and 12 hunting tooth guns were extended.

12 Tooth Hunting Cannons + 8 Small Cannons.

Su Mei kept controlling the lock: "Lock the No. 1 fortress, lock the No. 2 fortress, lock the No. 3 fortress! Fire!"

Attacking from all directions, Donglong City is like a big hedgehog with thorns sticking out, punching in all directions.

Su Mei destroyed the propellers of the three fortress cities at the same time, and the three fortress cities lost their power and became immobile living targets.

Yan Xue watched all this calmly: "The firepower in Donglong City is quite strong, order to fire! Hit me until they surrender!"

The shells of the 8 fortresses came from all directions.

Su Mei, twin girls.

And Wei Xian and the general public, all closed their eyes and waited for the cannonballs to fall.

8 fortress cities, 64 cannons come at the same time, can Donglong City withstand it?

This garden city will soon turn into ruins under the baptism of cannonballs!

Just hurry up and hit the thick golden projectile.

64 golden projectiles cut through the night sky and landed on Donglong City.

Boom! ! !

The dense explosions shook everyone's ears, and the entire Donglong City was shaking.

When Su Mei slowly opened her eyes, she could already imagine that Donglong City was littered with corpses and a mess.

But the moment she opened her eyes...

Silly.

Donglong City is intact, the botanical gardens, trees, flowers, and buildings are still so beautiful.

People on the street are also alive.

Everyone lay on the ground holding their heads, when they stood up, stupid? !

"Strange, the enemy hit us, why is there nothing in our city?"

Everyone is wondering, what's going on? What about enemy shells? Where did it go?

Only Wei Xian opened his eyes and watched at that time.

Wei Xian firmly believes that the city lord is not a fool, and he cannot let everyone enter the encirclement.

When the shells fell, Wei Xian was shaken inside.

But at that moment, he was like a ghost.

"Energy shield! There is an energy shield on Donglong City! Our city has an energy shield! Damn it!! The city owner is awesome!"

Energy shield?

The crowd went from shock to ecstasy.

Isn't that god-level technology?

Energy shield! God-level technology! I've only heard it mentioned in the big city, no one has ever seen it.

In the main building of Donghai City, Yan Xue's face was almost pressed against the glass.

"energy……"

"Shield!?"

The old adjutant's face can be described as wonderful.

8 fortress cities besiege Donglong City, they can't hurt him!

And Donglong City has already started to counterattack, destroying all the power systems of the eight fortress cities.

The eight fortresses of Donghai City were beaten to pieces that could not be moved.

Yan Xue's legs softened: "The plan is in! The eight fortress cities were led to the front by him."

At this time, the distance between the eight fortress cities and the main city was widened by more than 20 kilometers, and they could not care for each other.

This is Wang Cheng's trick. *
