Doomsday Superhero Summoning System

It can be seen from Diana's words that there are a lot of zombies inside. In this case, it doesn't matter if the double experience card is used. The levels of the six heroes must be upgraded as soon as possible to help him complete more tasks.

I took out the double experience card and used it directly.

System: "If you use the double experience card successfully, within two hours, the experience value of killing monsters will be doubled."

Two hours is not bad. He has five of them and saves the remaining four for later use.

Xin Zhao and Sword Master are very powerful in close combat. Facing the tide of zombies, it is still easy to deal with them with their current strength. With the help of Diana and Ai Xi, Zhou Yan is also on the sixth day.

There are heroes around to help them kill zombies together.

The strength of these zombies is very ordinary, but after being forcibly modified, their strength has become much stronger.

It would make sense if these zombies were evolved zombies. The evolved zombies themselves have some parts of the mutated beast's body, so they are much more powerful.

But just by looking at these zombies, you can see that they are not comparable to evolved zombies, which are much more powerful than these zombies.

There are still a lot of zombies, but no matter how many there are, there is no order at all. They all move based on instinct. In addition, they move very slowly, as if they have not recovered from surgery.

With the blessing of double experience, the six heroes continued to improve level by level, and they soon rushed into the depths of the monster.

"Why are there so many zombies?" They had gone a little far here, but there were still many zombies they saw. He really didn't know how many monsters there were here.

"More is not a good thing. This way we can upgrade faster," said Diana.

"Didn't you go deeper inside before?" Zhou Yan asked.

"No, why did you go in when you saw there are only zombies here? You all said there was something strange inside, so why didn't I see anything different inside?"

Diana had heard Zhou Yan always saying that there was something wrong inside, and originally wanted to go in and take a look, but there were all zombies like this inside. Although it was very weird, there was nothing special about it.

"Keep fighting in. I think our big movement must have disturbed the guy inside, and he will definitely make some movement next." Zhou Yan said.

"Can you guess this? What if it's not what you said?" Diana didn't believe what Zhou Yan said.

"No, I'm already right." Zhou Yan smiled.

"Already guessed it???" Diana was full of doubts.

"Look ahead." Zhou Yan pointed to a place in front.

They looked ahead and saw a huge black shadow slowly coming towards them. Although it was still far away, the black shadow could still be seen.

"It's not very clear, but from the outside, this monster is quite big." You can hear the monster's huge footsteps in the distance, and you can also see the trees in the distance shaking constantly, some of which are smaller.

The trees fell down directly.

"What kind of monster is this? It's at least eight or nine meters high. I don't know if this monster is different from other monsters." They were all waiting for this monster and wanted to see its strength.

how.
