Chapitre 832: Chapter 833: The Cost of High-Level Research

Chu You stared at the four characters for a while, just looking at them as if facing a major decision!

Then, with a thought, he chose high-level fortress research!

It could be seen that there were four high-level research options: battle, punishment, construction, alliance!

Each option was a mysterious and intricate card resembling a magic array, with four cards in total, each corresponding to one of the four high-level research options!

Below these four mysterious and intricate magic array cards was a grey galaxy nebula pattern, and beneath the pattern was a set of grey text displaying: Activate the Spirit of the Fort!

Since these words were greyed out, they could not be activated. So, what was the prerequisite for activating it?

Of course, the answer was to complete all the high-level research projects before qualifying to start this ultimate option!

As his eyes went over the four high-level options, Chu You first chose battle.
