Level 9 is the upper limit of all buildings, generally speaking, the first 3 levels only need normal resources to upgrade up, level 4 to level 6, then you need some conditions to upgrade, level 7 to level 9, in addition to reaching certain conditions, you will also need a lot of special materials.

The same is true for the Soul Tower, after Liu Zhi upgraded the Soul Tower to level 3 through resources, he encountered a situation, when level 3 was upgraded to level 4, a heart that lost its motivation was needed, and most importantly, the stronger this heart, the more effective it was for the promotion of the Soul Tower.

Looking at this explanation, Liu Zhi immediately set his eyes on the mechanical fish man who was dismantled, and Liu Zhi's side has dealt with a lot of things, this mechanical fish man has not been decomposed yet, and a large number of machines have been dismantled from the mechanical fish man one by one, and carefully put aside.

But soon Liu Zhi shook his head, the heart of the mechanical fishman could not be used, he had already seen that the power source of the mechanical fishman was not the heart, and the fishman placed in the mechanical body was just an ordinary hero, and he did not have much of a strong heart.

At this time, Ryuji's thoughts turned to Toga's corpse, although Toga's body was bitten off by a shark, he could be sure that the heart was still in Toga's body, maybe that heart could be used.

Thinking of this, Liu Zhi was also excited, and he didn't look too much, and he upgraded the Abyss Demon Reef to level 3 on the spot.

When he had finished his work, he took the Staff of Death, jumped into the Sun Carriage, and headed for Toga's corpse.

However, Ryuji didn't notice that after he gave the order, a large amount of resources hoarded in the Hades Palace were sent to the Abyss Demon Reef.

This is actually the focus of Liu Zhi's upgrade, after all, the next enemy will definitely come from the sea, and the Hades Sea area is the main battlefield, and the main building, the Abyss Demon Reef, must be upgraded to the highest level that can be improved.

When the Abyss Demon Reef was upgraded to level 2, there were some more reefs on the surface of the sea in the Hades Sea, and the location of those reefs even affected the current of the entire sea.

At level 3, a trace of electricity appeared on the extra reef on the sea surface, and these currents centered on the reef of the Abyss Demon, and a power grid was laid in the entire sea area.

Then, in the power grid, it seems that something under the water is constantly blowing up, and those things look like some parts of the mechanical fish-man, which are stimulated by the electric current, and actually explode on their own.

The grid swept back and forth in the waters of Hades three times, because no one controlled it, and no one noticed, before it slowly calmed down.

At the same time, in the depths of the sea, a huge shark up to 1,500 meters long is swimming slowly, this shark uses the mouth as the dividing line, the upper body is completely mechanized, it looks as if it is carrying a cruise ship on its back, and the lower part is no different from an ordinary shark, and the whole shark looks quite strange.

At this time, in a room at the head of the shark, a fishman about the height of a normal person is sitting on a chair, more than half of the fishman's body has been mechanized, and the only thing that has not become a fish-man is the head of the fish-man.

He played with a radar-like object in his arm until he put it down after a long time.

"The mark is gone, and it looks like they've spotted our target and have begun to clear the space."

"Lord Scale, should we ......?"

At this time, a fish-man standing next to him couldn't help but ask, this fish-man was a little out of place with the fish-man in the whole room, because he didn't have any mechanical appearance on his body, but instead wore all kinds of strange gold ornaments on his body to decorate.

"It's not in a hurry, the black pearl is charging, there is no way to open the passage for the time being, and we are far away now, the ability of the passage is limited, at most we can only send one more unit of troops over, last time the troops of one unit were folded in it, I don't think it will be useful to send another unit over.

Now what we have to do is complete the task in a short time, and then we will deal with it when I return with the army. ”

None of the other fishmen present said anything about Crazy Scales, only the fishman with gold ornaments looked at Crazy Scales with some concern.

"Lord Crazy Scale, will there be a problem in this way, you can stare at that space for a long time, what if we go over like this, and the things in the space are snatched away."

Crazy Scales glanced at the fish-man, and a trace of disdain appeared on his face, "What's there in that space, I'm staring at that space, it's all for the great cause of the empire, it's the closest base-type space to the most Fireblade City, as long as we can grab it, we can secretly lay nails near Fireblade City, if it's handled well, I can at least bury seven units of troops over there, you know, what the seven units of troops represent, and what does this mean for the great cause of the empire." ”

was robbed of such a white by the wild scales, and the face of the fishman with gold ornaments all over his body became not very good, but he couldn't say anything, so he could only chat there without embarrassment with a blue face.

Finally, after the fish-man left, Crazy Scale's face became ugly.

"Who leaked the consumption, have you lived enough? Forget it this time, if there is a next time, I will take you all and feed the sharks. ”

The faces of several of Crazy Scale's subordinates became quite ugly when they heard this, but they didn't dare to say anything, for fear that one of them would become the source of power for the huge shark at the moment.

After venting his dissatisfaction, Crazy Scale's face finally calmed down a lot, he looked up at his subordinates, and finally his eyes fell on a fishman, this fishman's body is also half mechanized, but he is a little strange in his mechanization, he is mechanized in all fours, and at the same time there are a large number of weapons and tools on his back, it can be seen that he is the kind of person who plans and then acts.

Scaly thought for a moment and pointed at the fish-man, "Zhisu, we still have some time to come back, the matter over there can't be delayed any longer, I'll give you three units of troops, you go and deal with this matter, remember, if you can't get something, then you have to stop the person occupying that space from taking it away." ”

The fish-man named Zhisu immediately stepped forward, and he didn't ask what to do, but just nodded affirmatively, turned and left the room.

Not long after, the giant mechanical shark opened its mouth, and three mechanical boats that looked like turtles swam out of the shark's mouth and slowly swam in the other direction.
