[Do you wish to upgrade to a top-tier military structure -- ancient elven tree?]
[Yes][No]
Mike looked at the ancient elven tree and with a thought, an information panel appeared.
"Yes!"
He had just made his choice, and in an instant, the earth rumbled and trembled.
The ancient tree behind Jonia began to undergo significant changes.
A large ball of green light bloomed from the entire tree.
Mike had already felt this green aura countless times! It was the rich life force!
The life force continued to revolve around the ancient elven tree, and the size of the ancient tree began to expand bit by bit!
The roots began to spread in the soil, taking root in deeper soil.
The leaves of the entire tree branch also became more lush and beautiful.
In the end, the green air continued to dissipate.
The ancient elven tree had doubled in size compared to its original level 3 appearance.
