Dark openings appeared on both sides of the fortress.

Each hole has a diameter of 100 meters.

There are 100 on each side.

That is, there are a total of 200 cave entrances, and a roar continues to come out of the cave entrances, and then a huge suction force comes out, and the direction is where the Demon Domain is located. Under the pull of the suction, the black mist that filled the demon domain tumbled and flowed towards the two hundred holes, and from a distance it looked like two hundred black dragons, each of which was thousands of miles long, thick and thousands of meters, rushing towards the fortress, which could be described as extremely spectacular. And the same thing happened in the other five directions of the Demon Domain, a total of six huge war fortresses, 1,200 huge holes, frantically sucking the black fog in the Demon Domain, as the war fortress absorbs more black fog, the war fortress's ability to absorb the black fog is also increasing, and the speed of absorbing the black fog is also accelerating, it is obvious that the war fortress can convert the black fog it sucks into its own energy.

Six huge war fortresses are like vacuum cleaners.

And the Demon Domain is like a room waiting to be cleaned.

No matter how big the room is, there will always be a day when it will be cleaned by a vacuum cleaner. As the six huge war fortresses continued to suck in, the Demon Domain was decreasing at a rate visible to the naked eye. Because after being sucked by the war fortress, a blank area gradually appeared, and the black fog disappeared, leaking out the scene inside for the first time, the dark blue sea, the blue sky, and then the war fortress began to advance rapidly, and continued to expand the results of the battle, little by little encroaching on the space belonging to the demon domain.

······

The war fortress of the Thunder Sect,

Control Lobby.

"Okay, good! The War Fortress can really absorb the life qi and grow, and it is not in vain that we have worked hard to prepare for three hundred years! As long as there is no protection from the Demon Domain, I will see how the Demon Gate will fight with the six factions of our righteous path. The Master looked at the image in the crystal ball with a deep look of joy on his face.

"Sanse, we can't be too happy, after all, the Demon Gate has been inherited for hundreds of thousands of years, how can there be no backhand? Yang Yi said with a worried look on his face.

"Haha, Thunder, you're a little worried, but don't forget, as the War Fortress absorbs more dead air, the War Fortress can continue to evolve. It's not that we haven't estimated, if we suck up the dead qi of the entire Demon Domain, all the war fortresses of our righteous path six factions fighting may have evolved to the Diamond Research Rank, think about it! The six huge diamond research level magic weapons, what kind of power should they have? Even if the Demon Gate has any conspiracy, what is it in the face of absolute power?" The Master of the Three Colors said indifferently, obviously very confident in the War Fortress, his eyes eagerly staring at the crystal ball.

"......" thought for a while, and Yang Yi didn't speak again.

What the Three-Color Venerable Master said was not unreasonable, judging from the performance of the War Fortress at this time, if he sucked up all the dead qi in the Demon Domain, there would be no problem in being promoted to a Diamond Rank Magic Weapon. If you are a little unlucky, you may even be promoted to a moonlight-level magic weapon, then you will make a lot of money. A large combination artifact like a war fortress is different from a small, tiny artifact, and there is no comparison between the two in terms of cost, complexity, or power.

From the cost point of view: large magic weapons are naturally far more than small and tiny magic weapons, the former may be a hundred times, a thousand times, ten thousand times, ten thousand times, and even more, so large magic weapons cannot be made without large factions; In terms of power: large magic weapons can be said to be killing machines, far from being comparable to small and tiny magic weapons, because in terms of the total amount of energy that can be mobilized, large magic weapons are hundreds, thousands, and ten thousand times that of small and tiny magic weapons, and there may even be more, so the power will naturally be stronger.

Of course, there is another drawback to large magic weapons.

That's complicated.

A large number of manpower is required.

"Master, if there is no dead qi to conceive, will the level of the war fortress continue to decline?" Looking at the magnificent two hundred black dragons in the crystal ball, Guo Tian was naturally shocked in his heart, and couldn't help but ask.

"Yes, the War Fortress can be regarded as a magic weapon, but there is no Demon Spirit, but with the continuous upgrading of the War Fortress, it should soon be able to give birth to a Weapon Spirit, and it can grow rapidly. Yang Yi nodded and gave Guo Tian an appreciative look, obviously very satisfied with Guo Tian's sober mind.

As soon as Yang Yi's words fell, the image in the crystal ball suddenly disappeared.

Didn't wait for everyone to react.

A cloud of black mist appeared in the crystal ball.

Constantly twisting,

Tumbling, changing shapes.

"Hello!" a wave of mental turmoil came from the black mist. Timid, like a boy carved in pink, hiding behind adults and not daring to come out to meet people, such a picture naturally appeared in everyone's hearts.

"Machine Spirit! Machine Spirit actually appeared so soon?" Yang Yi stood up suddenly and exclaimed.

This is the newborn machine spirit?

Everyone was stunned.

How can the War Fortress be said to be a large magic weapon, and the machine spirit is just like this? It's a bit too cheap, right? However, the three-color master was happy, staring at the machine spirit and muttering to himself, "Great, the machine spirit was born so quickly, which proves that the machine spirit still has a lot of room for growth, and now it is really a treasure." ”

"Three colors, I think it's better to destroy it, we all know that magic weapons are below the diamond level, and it is impossible to give birth to a machine spirit, and the war fortress is now only a black iron research level, how can it be possible to give birth to a machine spirit? In order to be safe, we better destroy it, otherwise it will be a big problem if it gets out of control. I don't know how to do it, Yang Yi felt inexplicably irritable in his heart, and opened his mouth to persuade.

"Don't destroy me, I'll listen to you!"

The black mist tumbled sharply, and there was a fluctuation of spirit. (To be continued.) )
