Doomsday Superhero Summoning System

This is an astronomical figure. The further back the City of Heroes goes, the more things need to be built and purchased, and the energy points required for upgrades also increase several times.

After the level of the City of Heroes reached level five, Zhou Yan smiled bitterly. All his crystal cores were used up, and all the crystal cores he had collected since the end of the world were gone.

This is an astronomical amount of money. If these crystal nuclei are used to cultivate evolvers, at least tens of thousands of fifth-level evolvers can be cultivated. However, these crystal nuclei only upgrade the City of Heroes to level five.

After the City of Heroes reaches level five, basically all the buildings in the city are available, including roads, greenery, residential areas, commercial areas, barracks, shops, etc. These are all built by him spending a lot of energy points.

After the fifth level of the City of Heroes, the entire city has reached an area of ​​10 million square meters, which is 10 square kilometers. In fact, for Zhou Yan, this city is a bit too big.

Originally, he didn't plan to let others live in it, but when he thought that the City of Heroes required a huge amount of energy points to improve, he still needed evolvers, but he wouldn't accept everyone, and not everyone could come in.

.

Anyway, no one can enter the City of Heroes without his consent. This is a city taken from the system. Without a pass from the City of Heroes, even a tenth-level evolver cannot enter.

It is still possible to force your way in, unless you can break through the defense on the city gate. Every city wall, including the city gate, is durable. As long as the durability is attacked to 0 points, the defense function will disappear.

However, these durability can be replenished by consuming energy points, and they can also be replenished automatically. As long as the energy points of the city lord crystal are enough, to a certain extent, the City of Heroes will not be destroyed.

It would be difficult for him alone to collect enough energy points, which required the help of other evolvers. He considered turning the City of Heroes into a trading city, and he also had the capital.

Rows of defense towers have been arranged on the walls of the City of Heroes. Now these defense towers have begun to attack the terracotta warriors outside the city. There are still many soldiers on them attacking the terracotta warriors outside the city.

Minions are not just minions, they are also divided into four types: archers, spearmen, sword and shield soldiers, and mage soldiers. Killing these monsters can not only obtain energy points, but also improve the level of the minions.

As the city lord, he can gain a small amount of experience points. Of course, he does not need these experience points, which can be adjusted according to percentages.

He has recalled all the heroes he purchased and is now killing the warriors outside on the city wall. However, when fighting in the City of Heroes, he has no gold coins or materials to harvest.

After all, killing these monsters would already increase the city's energy points. If he had more gold coins and materials, he would almost not want to go out to hunt monsters elsewhere.

Now the City of Heroes can collect energy points within five kilometers. As long as people from the City of Heroes' forces kill monsters within this range, they can increase the energy points of the City of Heroes.

Except for the low-level soldiers who could only stand on the city wall to attack the terracotta warriors, the summoned heroes had long been thrown outside the city to hunt the terracotta warriors. Zhou Yan asked them not to leave the city of heroes five kilometers away.

Just let them go.
