Doomsday Superhero Summoning System

In the lobby of the City Lord's Mansion, there is one thing that is the most special, which is the red energy crystal. The crystal is glowing with light, filling the entire City of Heroes with a warm feeling.

It is simply two extremes from the gloomy environment outside the City of Heroes.

This crystal was very familiar to Zhou Yan. It was the most important crystal in every base in the League of Legends. It just lacked a defense tower. However, when he learned about the City of Heroes, he discovered that it was not that there were no defense towers, but that he had not purchased them.

Through understanding, the crystal of the city lord's palace is also the most important place in the entire city. Once the crystal is shattered, his city of heroes will no longer exist. This does not mean that the city of heroes will disappear, but it still needs to be completed again.

It takes twelve systematic tasks to regain the City of Heroes.

You know, it took him half a year to complete this city of heroes, and he encountered countless dangers. He didn't want to complete it a second time.

The current City of Heroes is only a first-level city. To upgrade to a second-level city, many conditions are required.

First: Upgrade all buildings in the City of Heroes to Level 2.

Second: At least 10 heroes and 100 soldiers are required to garrison.

Third: Consume 10,000 energy points.

First of all, let me explain that the source of energy points can be obtained from monsters. As long as you kill monsters within a hundred meters of the City of Heroes, you can obtain energy points.

The number of energy points is related to the level, quality, and type of the monster.

I don’t know where it comes from. It can also be improved by completing system tasks, city lord’s mansion tasks, and by absorbing the energy of the crystal core.

"Fortunately, I kept a lot of crystal nuclei, which really came in handy now." Zhou Yan couldn't help but be lucky.

He has been collecting crystal nuclei. Although he has used a lot, the total amount is still quite a lot.

You have to know how many crystal cores he got from selling equipment, and he also killed those small bases that were not instantaneous along the way. The number of crystal cores harvested from them was not a small amount, and there were also various kinds of crystal cores harvested from destroying alien bases.

He also sold all the weapons.

He can say that absolutely no one has more crystal nuclei than him. He alone is equivalent to the total number of crystal nuclei of many powerful forces. Zhou Yan is definitely the richest person in the world.

It is not difficult to upgrade to the second level Hero City. He has more than ten heroes, and in the Hero City, he can summon all the heroes he purchased.

As for the soldiers in the city lord's palace, he read the introduction carefully, and immediately became happy after seeing it.

In the city lord's mansion, the level of the minions can also be upgraded, but if you want to upgrade, you need to consume energy points to upgrade. He can also purchase level 10 minions at one time.

Level 10 minions can be directly purchased in first-level cities, but the price is much higher than level 1 minions.

There are not only minions, but also elite captains, centurions, captains of thousands, and captains of ten thousand. However, because the current City of Heroes is only a first-level city, only minions are unlocked.

As for the others, they can only be unlocked after the level of the City of Heroes increases.

The tallest among the soldiers was only the captain of ten thousand men, and there were no generals. Zhou Yan actually wanted to understand this. With these heroes, there would be no need for generals at all.
