After a salvo, the sun and Poseidon fortress got rid of the attack of the giant wolf spacecraft and flew to the moon.

Outside the crater, Wang Dali frowned.

"Optimus Prime, you're kidding. Where's the fortress?"

Wang Dali is really worried. You can't joke at this time.

"Yes, the passage is in the crater!"

Poseidon said, suddenly the fortress emitted a powerful laser, which exploded in the center of the crater. Suddenly, the bottom of the crater slowly opened, revealing a huge and deep cavity.

Wang Dali looked at the big screen and his eyes widened.

"I wipe, there is a base under the crater?"

I can't think of it.

Two giants flew into the cavity, and the cavity led to the dark depth. Where the spacecraft passed, it immediately lit up a very bright light.

Wang Dali saw that a huge passage led to the depths of the earth. I don't know how many kilometers it was, and there was no end at all.

The four walls of the passage are all silver gray metal. There are transverse passages everywhere. It is an underground maze extending in all directions.

This is completely a fortress of steel, its vast, I don't know how to describe it.

"The bunker is gone, and the baby suspects that the moon is empty -"

"It feels like a steel fortress in the moon -"

"It's amazing. I didn't expect such a scene in the lunar crust --"

"Is such a big steel fortress built by mechanical civilization?"

"The blockhouse of mechanical civilization is completely unimaginable -"

On earth, hundreds of millions of viewers are Sparta! The world in front of you is a magnificent steel fortress. It seems to be as big as the moon?

"Optimus Prime, what fortress is this? Why is it so magnificent?" Wang Dali's voice trembled. The vastness of the fortress has overturned the imagination.

"Ha ha, this is the Planetary Fortress I said. In fact, the moon is a star fortress. Long ago, our mechanical civilization arrived here and built such a fortress inside the moon. Its purpose is to protect the earth!"

Optimus Prime also had some feelings. It was too long ago. He learned all this from the leadership module. Otherwise, he really didn't know.

The chase of the giant Sirian spaceship flew around the moon without its door.

The wolf man's Mothership bombarded the surface of the moon, and the craters collapsed, revealing the silver gray surface of the metal fortress.

"Attack, break it!"

The commander of the giant wolf star man roared that he came to the earth this time to conquer the earth civilization. All the spaceships just now have to be destroyed. Otherwise, why would the earth civilization be enslaved?

The terrible anode magneto-optical guns bombarded the lunar fortress, and the vibration rang through the whole moon.

Wang Dali and his party were deep in the lunar fortress and still felt the shaking of the whole lunar fortress.

"The situation is urgent. The giant Sirians are attacking the fortress!" Optimus Prime looked up and said, "Poseidon, how long can this fortress resist?"

"More than three hours, if you don't make any counterattack!" Poseidon said.

"Then fight back quickly!" Wang Dali said.

"You must go to the command center of the lunar fortress. Only by starting the wisdom center can you fight back!" Poseidon said.

"Hurry up!"

Poseidon fortress and the sun spacecraft flew into the depths of the moon and came to a huge apron. A spherical command center was suspended above the apron.

Enter the command center.

Optimus Prime took out the leadership module and pressed it into the intelligent central system of the center. Suddenly, the whole command center became bright and the light spread to the whole lunar fortress.

The rumbling sound came from the core of the moon.

"What's that sound?"

"It is the star nuclear furnace of the fortress, which can provide inexhaustible huge energy!" Poseidon said.

"Moon god, can you fight back?" Optimus Prime took back the leadership module, reloaded it into his heart, then looked up and ordered.

A mass of light appeared in the center of the command center and condensed into a metal mask.

"This is the moon god, the wisdom center of the moon fortress?" Wang Dali was surprised. He really felt metallic and deserved to be a mechanical life.

"If you detect a threat, you can fight back!" the moon god hurriedly said.

"Fight back immediately!" Optimus Prime quickly gave the order.

The surface of the moon suddenly roared, and anode magneto-optical guns were raised. Almost at the same time, they began to condense full power energy.

Boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom

Countless dazzling magnetic lights rushed out from the surface of the moon and directly hit the giant Sirian spacecraft in the sky.

Whether small or medium-sized spaceships or huge motherships, they were hit in an instant and soon exploded.

Earth people and various observation instruments observed that there was a huge explosion on the surface of the moon. Countless spaceships and motherships disappeared completely after the explosion.

"I wipe it. It's too powerful. This is a volley of the lunar fortress?" Wang Dali was shocked.

"The first round of volley is over, and the enemy is completely wiped out!" said the moon god.

Optimus Prime was also shocked. It was too powerful. Did the giant Sirian fleet be completely eliminated? The earth crisis was lifted under a round of volley from the lunar fortress!

"Long live -"

"Victory -"

"Damn alien invasion, declared bankrupt -"

People cheered one after another. This is a day worthy of being remembered by all mankind. This is the independence day of all mankind!
