Doomsday Superhero Summoning System

The boss's health finally began to decrease rapidly, especially after the heroes destroyed all the remaining zombies, and Zhou Yan prevented the boss from breathing at all.

As long as the hero's health is not enough, he will be summoned back directly, and then a new hero will be summoned to appear. It is such a round-robin battle that the boss is defeated without saying anything.

Even if the boss had other means, Zhou Yan didn't give it a chance to activate it. Qin Tian and Simaco simply went out to the door and replaced two heroes. In this way, the death of this boss was closer.

It seems that Zhou Yan was favored by the goddess of luck, and he was upgraded. This was also thanks to the fact that there was a hero outside who was killing monsters. His experience points were almost full and he was finally upgraded.

Resurrected with full blood, clearing all negative status, Zhou Yan himself also increased his output.

Now there are four powerful heroes, Zhou Yan, Diana, Juggernaut, and Xin Zhao in front, and three long-range heroes Ashe, Sivir, and Tristana behind. The boss's health has finally been reduced to 20%.

To be honest, this is the most difficult boss they have ever encountered, bar none.

The heroes had to change twice to defeat the boss to this point. They had to attack this boss for at least forty minutes. This is how powerful the platinum boss is, and this is how terrifying the forty-level platinum boss is.

After all, Zhou Yan's level is still too low. If they were all above level 40, they would never have spent so much time.

He still had a few double and triple experience value cards that he had not used yet. He originally wanted to find a place with many monsters to use them, but he never found a suitable opportunity.

After all these things are resolved, it's time to upgrade properly.

Fifteen percent.

Ten percent.

The boss's health has dropped to its final percent health. As long as they complete the last wave, they can successfully kill this platinum boss.

"Everyone, please work harder." Zhou Yan said.

"The boss is about to launch an offensive again." Ai Xi observed from a distance.

"Release the ultimate move." Zhou Yan had reserved this move for a long time just to interrupt the boss.

A series of attacks bombarded the boss. The boss who was about to launch a move was instantly attacked to pieces, and he probably couldn't even find his direction.

"here you go."

This round of ultimate attacks finally severely injured the boss. The boss immediately lost 5% of its health, leaving only the last 5% of its health.

Even so, they will not underestimate the enemy. Failure often happens when you relax your guard the most.

"It's a pity that this armor is gone." Although the armor on the boss is made of meteorites, after such a violent attack, there are some signs of damage. It is not the iron pieces that are broken, but the silk threads connecting those patches.

Dropped.

Therefore, their attacks can directly hit the boss's body through those gaps, which can cause greater damage to it.

"discipline!"

"Ignition!"

"Thunder Step!"

Zhou Yan released his skills continuously, then rushed in front of the zombies, attacked the Greedy Hydra with all his strength, and finally killed the platinum boss.

"boom!"

The boss finally fell.
