Doomsday Superhero Summoning System

To put it bluntly, there are not many monsters that can block any hero's attack.

The attacks brought about by the equipment upgrade are absolutely terrifying. In addition, the heroes are all above level 90, so they are only within ten levels from reaching full level.

It can be said that the current heroes have already reached their peak period, not to mention that their current ranking has reached the diamond level.

As for Zhou Yan himself, his strength should have been described as terrifying. Even if he faced the attack of three heroes, he could remain invincible. However, if five heroes attacked together, he would have no choice but to escape.

If he wants to leave, no one in the world can stop him. He has too many ways to save his life, and he can even use the summoner skill to revive.

It's just that the resurrection skill comes at a high cost. It takes ten levels to use it once!

The more advanced he is, the more he understands how difficult it is to upgrade. He definitely doesn't want to exchange a tenth level for a resurrection.

After staying in other countries for nearly seven or eight months, the teleportation arrays in many countries were built. The losses abroad were absolutely huge, and even many small countries were basically wiped out.

A large part of the land was occupied by foreigners, and then they established their bases and even cities.

There are also some friendly, highly civilized aliens looking for cooperation with Zhou Yan's City of Heroes. Of course, if they hadn't seen Zhou Yan's City of Heroes as powerful, they wouldn't have cooperated with him.

The cooperation between the two parties is very simple, which is to trade the items they each need. They can bring various items from the high-tech civilization in the universe, weapons and armor, advanced technology, etc.

Zhou Yan was naturally happy to accept that the things they traded used crystal nuclei. Some friendly aliens told him that these crystal nuclei also had a great effect on them.

A large part of the reason they came to this planet was to collect these crystal nuclei.

Crystal nuclei are the basis for evolvers to improve their strength. Zhou Yan also understands that although many aliens are technologically advanced, their physical fitness is not that strong. They want to improve their own strength by absorbing these crystal nuclei, coupled with high-tech

With help, the strength will become stronger.

This planet is not the only one in the world that has this thing. Even if Zhou Yan refuses to cooperate, they can still find other planets. Currently, he does not have the ability to leave the planet, so in the face of their request, both parties cooperate happily.

Sooner or later, he will step outside the universe one day, and it is not impossible to even find a route back to Earth.

I didn't dare to think about it before, but as long as I have the strength, everything is not impossible.

Zhou Yan has made friends with many foreigners. Naturally, these foreigners are not enemies. The enemies have already died in his hands. As long as they are hostile forces, he will not show mercy.

This time he will go to the Elf Forest. This name is naturally the name of the elves themselves. They have regulated this area to their territory, but they seem to be in trouble. Several beautiful elves have come to him for help.

His current reputation is not only famous among humans, but also famous among other races. He knows how many alien races he has wiped out. How could they not know about such a major event?

This is also the reason why the elves are looking for him, because their current opponents are a group of ferocious races. These races are very aggressive. The elves are unable to defeat them, so they can only ask Zhou Yan for help.
