Doomsday Superhero Summoning System

The monster siege time on the second day was two hours, one hour longer than yesterday. This only gave the city an extra hour to collect energy.

Just like yesterday, after the monster siege was completed, all the monster corpses outside the city were refreshed by the system. It looked like nothing had happened. Zhou Yan once again took a dozen heroes out to hunt monsters and obtain gold coins.

On the third day, the monsters attacked the city. The lowest level became level 30. At the same time, there were more flying mutant birds attacking. The monsters attacking this time were zombies and mutant beasts.

The monster siege on the third day will last for three hours, and the number is twice that of yesterday. There are more monsters, and it will take time for the heroes to kill them. These monsters are close to the city wall.

It’s just that there are two rows of defense towers on each city wall. These defense towers can attack monsters within a range of 500 meters. They are like cannons. They can kill a large number of monsters with each attack. The only thing is the attack speed.

Not fast, but definitely very powerful.

Although there are monsters approaching the city wall, facing the tall city wall, these monsters cannot jump to the city wall at all. They can only climb the city wall with their claws. However, the soldiers on the city wall are not decorations. They continuously fire various bows and arrows.

, magic, and bullets, so none of the monsters can reach the city wall.

The number of these monsters that can approach the city wall is very small. Without a steady stream of monsters, there is only a dead end. In three hours, at least two to three million energy points were added to the City of Heroes, which made him happy.

In the end, hundreds of thousands of energy points were spent to repair the defensive function of the city wall, and he took a dozen heroes out to hunt monsters.

When he came back, there was another hero beside Zhou Yan, the outlaw Graves. He was already over level 30 at this time. After all, the lowest he hunted were elite monsters of level 80, which gave him huge experience points.

Naturally, it allows him to level up quickly.

At this time, his number of heroes reached 67.

When the fourth day came, Zhou Yan knew that today's battle would be more difficult than the previous few days, but their overall strength was not weak. The level of 10,000 soldiers had reached more than 40 levels, plus most of the heroes'

The levels are all close to level 70, and the lineup is quite strong.

At nine o'clock, the system's voice sounded again, and the monsters outside the city had arrived. The lowest level of today's monsters was level 40, and the highest level did not exceed level 80, but level 75. This did not count the pressure on them.

Very big.

He spent energy points to buy several double experience cards from the city lord's mansion. Each card could last for two hours. He used one without hesitation.

Today's battle will last for four hours. When Zhou Yan fights outside, he has to fight for at least eight consecutive hours a day. For them, four hours is only half of it.

The types of monsters today are very diverse. Some are relatively powerful, some have relatively strong defense, and more are relatively fast. There are also some monsters with long-range attack capabilities.

This caused a certain amount of damage to the city walls and defense towers, and even many of the soldiers on the city walls were directly killed by these monsters.

If there is a war, there are bound to be casualties. He has known this for a long time. You can still buy the soldiers after they die, but he will feel bad if the heroes lose one level.
