Even if he doesn't have to cover the entire area, it's still a huge investment.

It's not necessary at the moment.

But this idea provided him with ideas for future renovations.

The seller who sold the earthquake tower asked for a replacement defensive tower.

However, Cheng Shen took the initiative to contact him and finally got it for 30 gold.

Then he bought some materials needed to upgrade the defense tower.

Abyss stones, energy stones, hellfire crystals, etc...

The more than 40 golds were quickly depleted.

After the money is spent.

Cheng Shen looked at the pile of materials in the warehouse with a sense of accomplishment.

He earned this all with his own hands.

Without relying on any external force,

He thought that being able to do this in the last days would be considered a success, right?

Start upgrading!

first.

It is a lightning tower that has been upgraded to level six.

It now requires 20 copper ingots and 8 gold coins to upgrade to one level. When it exceeds the tenth level, the requirements have increased to 30 copper ingots and 10 gold coins.

Cheng Shen only upgraded it to level 10.

There are not many copper ingots.

He also sets aside 50 units to upgrade the territory center.

A level 10 lightning tower is enough.

【Lightning Tower】

【element】

[Level: Excellent]

【Level:10】

【Attack:170】

[Attack speed: 1.5]

[Range: 75]

[Characteristics: Each lightning bolt can bounce five times between close targets, and the damage of each bounce is -15%. When it comes into contact with standing water, the number of lightning bounces is doubled, and it is no longer subject to the effect of diminishing damage]

…

After all, the Lightning Tower is a sophisticated defensive tower.

The improvement is limited.

Breaking through level ten only increases the number of ejections by one.

However, the basic attack has been improved a lot.

Before level 6, it only adds 10 attack points per level.

After level six, you can add 20 points.

If you break through level 10, 30 points will be added.

A basic attack of 170 points is already quite powerful.
