Doomsday Superhero Summoning System

A level 1 minion only requires 100 energy points, while a level 10 minion requires 10,000 energy points. This is a bit uneconomical. It is better to just buy a level 1 minion and upgrade slowly.

Even though he has a lot of crystal cores now, if he wants to build this city of heroes well, the crystal cores he has now may still be a drop in the bucket, so he will save what he can.

Naturally, the City of Heroes also sells other items, such as defense towers, defense artillery, defense crystals, etc., but these items are in a dark state and have not been unblocked. Many of them even show question marks, so we can only wait until the heroes are upgraded.

We will talk about the level of the city later.

He took out a lot of crystal cores and directly filled the crystal energy of the City Lord's Mansion to 1,000,000 points. Then he purchased 1,000 level 1 soldiers at one time, and then upgraded all the buildings in the City of Heroes to level 2.

The current City of Heroes has only a few buildings: four walls (including the gate), the City Lord's Mansion, floor tiles, and the City Lord's Crystal.

The four walls can only be upgraded together, and upgrading to level two requires 40,000 energy points.

Upgrading the City Lord's Mansion to Level 2 requires 50,000 energy points.

It takes a total of 10,000 energy points to upgrade the floor tiles in the entire city to level two.

As for the City Lord Crystal, upgrading to Level 2 is the most expensive and requires 100,000 energy points.

There are only these four buildings in the first-level City Lord's Mansion. Zhou Yan upgraded them one by one, consuming a total of 200,000 energy points. Including the energy points for purchasing minions, a total of 210,000 energy points were consumed.

System: "The City of Heroes has been upgraded to Level 2 and new buildings have been unlocked. Please check by yourself."

"brush!"

The entire City of Heroes seemed to be upgraded, shrouded in a golden light, and then we saw that the City of Heroes had become larger, and the city lord's palace was also larger and more imposing.

The area of ​​the City of Heroes has also increased from 10,000 square meters to 100,000 square meters, an increase of ten times at once.

Moreover, when the City of Heroes expanded before, all the blocking buildings disappeared, including those terracotta warriors who appeared at a loss on the edge of the city wall because of the emergence of the City of Heroes. They were all turned into energy points, which made Zhou

Yan didn't expect it.

After looking at the conditions required to upgrade the City of Heroes to a third-level city, there are many more than before. First, it is necessary to establish roads leading to the four city gates with the city lord's palace as the center.

There are also other buildings that need to be built, at least four. These houses have fixed locations, just on both sides of the road, so he only needs to consume energy points to build them directly.

You also need to purchase at least two defense towers and place them in the city lord's palace to protect the energy crystal. The number of soldiers must reach 1,000, the total number of heroes must reach 20, and all buildings in the city must reach level three.

These conditions are not difficult. Anyway, as long as you have energy points, you can keep improving the city.

It cost a total of more than half a million energy points to upgrade the City of Heroes to level three. Then I looked at the energy points required to upgrade the City of Heroes to level four. It was estimated that it would be at least two million points.

He was still able to come up with this. After purchasing all the things he needed, he upgraded all the buildings that needed to be upgraded, and finally consumed 2.35 million energy points.
