Doomsday Superhero Summoning System

Zhou Yan didn't expect that his skills were so terrifying. He looked at his mana and found that he had consumed 500 points!

You know, his current mana points are only 1900 points, and he lost so much in an instant. The mana cost of this skill is really amazing, but it is also very powerful, and the attack range is more than 100 meters.

This skill is so powerful that when it appears, it is like thunder falling from the sky. It is indeed a thunder that shakes the sky.

Looking at the cooldown time of this skill, it turned out to be twenty minutes. He found that his skills all had extremely long cooldown times, but he still had skill points. If he upgraded the Thunder Nine Heavens, the power would be increased, but it would consume more.

The mana value will also increase, and the gain outweighs the loss.

He gained a large amount of experience points and gold coins. The attack range of this skill is very far, up to several hundred meters away. He now has both long-range attack and melee combat capabilities, which can be regarded as a full-career development type.

Character.

After the smoke and dust cleared, a large hole appeared in the distance. This was all caused by his Thunderous Nine Heavens attack. The power of this skill was so powerful that all the monsters inside were naturally killed. There seemed to be one among them.

Only a small BOSS.

This move is completely a ultimate move. Almost all of his skills are ultimate moves with long cooldowns. This skill is pretty good. His other summoner skills have longer cooldowns. He doesn’t know if it’s intentional.

Aimed at him.

The heroes naturally noticed this and asked Zhou Yan when he got this skill. It was so powerful. However, Zhou Yan also told them the weakness of this skill. It requires 500 mana to be used once, and it has a long cooling time.

Up to 20 minutes.

These two limitations mean that this skill cannot be used as often as their skills, which I have to say is a bit uncomfortable.

He can also wear equipment that increases skill cold shrink, but he doesn't have to. Anyway, he can just use this skill as a ultimate move.

Zhou Yan rushed all the way to Ai Xi's side. Ai Xi was very confused and asked: "Why are you here?"

"I'll give you a good thing, otherwise your summoning time will come soon." Zhou Yan smiled mysteriously, and then directly put the time turntable into Ai Xi's hand.

"What is this?" Ai Xi looked at it in confusion, and immediately shouted: "You actually got this!"

System: "Whether to use the time turntable on Ice Shooter Ashe? Once used, it cannot be restored."

"yes!"

System: "Congratulations to the summoner for summoning the hero Ice Archer Ashe, the summoning time limit has been lifted."

"You..." Ai Xi's moving eyes kept looking at Zhou Yan. She didn't know whether it was to express gratitude or something else. They were so bright and moving that Zhou Yan immediately hugged Ai Xi and said in her ear: "I just want to

Let you always be by my side."

Such an affectionate confession made Ai Xi flustered for a while. She immediately blushed, pushed Zhou Yan away, turned to one side and said, "The zombies are coming, I have to help Diana."

After saying that, he resumed his bow and arrow posture, and continued to attack the zombies in the distance.

Zhou Yan smiled and also attacked the zombies.

As time goes by, there are more and more zombies, but there is a benefit to so many zombies, that is, they have all been upgraded. Because Zhou Yan just upgraded, he has not been upgraded.
