Doomsday Superhero Summoning System

"We're finally here." Looking at this tall stone gate, it is six meters high and ten meters wide. Two giant dragons are carved lifelike, with teeth and claws showing, majestic. Two golden rings are inlaid on the stone gate, divided into two stone gates on the left and right.

There are four vigorous and simple characters at the top, which I don’t recognize.

Yes, I just don’t know it. He didn’t learn the writing at that time, so he could only understand that the last character should be “dian”, but he didn’t understand the first three characters.

"Open!" Zhou Yan asked two tall tank heroes to step forward and push the door open. After going through countless hardships, they finally welcomed the rightful owner.

"Rumble!!!"

No matter how heavy the stone gate was, it could not withstand the powerful strength of the heroes, and it was quickly opened.

It was bright inside, very big and wide, with hundreds of civil and military officials standing on both sides. They bowed respectfully to their superiors, and there was a pool-like place in front of it. In the center of the pool was not a dragon chair, but a

A coffin.

Those pools had a pungent smell and were sparkling white. Zhou Yan could see what they were as soon as he looked at them. It turned out to be mercury.

A pool full of mercury, how much manpower and material resources it takes to collect it. As expected of Qin Tiandi, only he can collect it.

The coffin in the center is very huge and is made of huge rocks.

"Whoosh!"

As soon as they entered the main hall, hundreds of motionless civil and military figures of officers and soldiers immediately moved, turned their heads with red eyes, looked at Zhou Yan and the others, and then all attacked them.

Zhou Yan was shocked when he saw them. They were all bosses, the lowest were gold level bosses, most were platinum level bosses, and there were actually ten diamond level bosses.

"This is the boss's nest." Zhou Yan smiled, this is a big harvest.

There are hundreds of bosses, and they only have more than a hundred people. On average, one person has to face more than three bosses. This is not a problem for them. Zhou Yan is just worried about the last boss, Emperor Qin Tiandi.

Whether he will suddenly lift the coffin board and jump out is something that must be paid attention to.

When the battle begins, the heroes form a defensive formation. With so many human shields, the heroes behind do not need to worry at all, so they can just deal as much damage as they want.

Gain magic use, attribute improvement, attack improvement, attack speed acceleration, and at the same time restrict enemies, reduce their speed, attack, action, limit skills one by one, allow skills, knock-up skills are used continuously, heroes focus fire to attack a target, very

A boss can be eliminated quickly.

This is their advantage. Under the numerous fire attacks, not many bosses can survive for too long in front of them. This is the result of dozens of ADCs and mage heroes attacking together. If they are not strong, they will not be worthy of their status.

One boss after another fell, the heroes recovered when their health was low, drank medicine when their mana was insufficient, and always maintained the heroes' health above 90%. In short, they did not let them break through the tanks' defensive formation.

The assassins have already been dispatched. They use their speed to fight these bosses in the hall, and even with the cooperation of several of them, they can display greater strength.

The number of monsters is decreasing, but their strength has not decreased at all. With this increase, Zhou Yan is more confident in the upcoming battle.

There are still three hundred, two hundred, one hundred bosses left, and there is a sudden change.
