If Tiangong Fortress exists as a mobile city, then it is the best way to go underground. Once the fortress is completed, it will be moved directly with the superstructure, just like devouring the city. It will carry a large number of residential living areas, which can not only be used to arrange goblins, but also serve as peripheral protection.

Yuan Chenfei sighed: "So, in addition to solving the problems of the Demon Cannon and the Sky Screen system, I have another Tiangong Fortress now, right?"

Qu Wei immediately said: "The Tiangong Fortress should not have been built yet, so don't worry about it."

"On the contrary, I think the one that needs to worry about the most is it." Yuan Chenfei said.

"Hmm? You mean..."

"As long as Tiangong Fortress completes the infrastructure, it is likely to be a acropolis of the Golden City. When all attacks aim to destroy the Golden City, when we think we are about to complete the mission, a fortress suddenly appears..."

Qu Wei took a deep breath: "I understand, thanks to your reminder. What should I do now?"

"Since you already know the enemy's arrangement, of course you are going to get it done."

"But you don't know how to get into Tiangong Fortress!"

"No, I think I already know." Yuan Chenfei said as he moved his direction and walked towards the Demon God's Fortress.

The Tiangong Fortress must be under the Demon God Fortress.

The reason is very simple. As a battle fortress where the goblin tribe can attack outside, the goblin tribe has no reason not to transplant super killer weapons like the Demon Cannon.

A powerful battle fort must have strong firepower, and the Demon Cannon is the best choice.

And this is why the Goblin tribe was able to release the core crystals - the transformed demon cannon is getting rid of its dependence on the City of Monsters.

At this moment, Yuan Chenfei arrived in front of the Demon God's Fortress Base.

There are only two goblin guards at the door of the Demon God's Fortress Base.

However, unlike the Giant Camp, this place is definitely a defensive measure that is loose on the outside and tight on the inside.

But there are not many guards, there are many eyes of breaking the delusion, monitoring the fluctuations of space, and there are many eyes of the sky.

It can be imagined that there must be external monitoring of goblins inside, and even if you use hypnosis, you cannot pass the level.

"It's a little troublesome."

Yuan Chenfei lowered his head and thought for a moment.

If this is the case, I'm afraid I'll have to make some sacrifices.

Yuan Chenfei walked away.

Half an hour later, he returned here and watched the Demon Fort base and released a silver phantom.

"Xiaoyin, it's up to you now." Yuan Chenfei said.

The silver phantom nodded and began to make a teleportation alchemy array.

A teleportation alchemy array is soon completed.

Yuan Chenfei took out the remote control and pressed it.

boom!

A large explosion suddenly rang out.

The alarm sounded instantly throughout the sky.

"Attack!"

"Discover space fluctuations!"

"There is an enemy who is teleported into the city!"

The call of goblin soldiers sounded from all directions at the same time, and strong spatial fluctuations swept across the world, and all devices equipped with spatial fluctuations issued a whimpering alarm at the same time.

Yuan Chenfei has activated the secret magic ball, and the next moment, the scene of the Flower God Fortress reappears.
Chapter completed!
