Clearly, to upgrade the Fortress Spatial Skill Strengthening research project to level 10, the consumption of all sorts of resources was astronomical!
Take Gold Coins for instance, aside from the fifth level where Chu You used a free upgrade card, and besides the first level which had already been upgraded, the total Gold Coin consumption amounted to: 49 million!
Therefore, Chu You still had over 100 million Gold Coins on him!
As for Scientific Research Acceleration Cards, 1,450 days were consumed, out of a total of 3,880 days of acceleration cards, leaving Chu You with: 2,430 days.
Chu You knew that if he accounted for the Research Acceleration Cards and the consumed strategic resources and converted them into Gold Coins, that number could be close to 80 million Gold Coins!
This was high-level research! This was full-level high-level research!
One thing must be clear!
