After entering the Offline Training Ground (you must have God's Blessing), you will receive the following message.

Click "Level Up" to continue, and it will cost you a certain number of Red Stones. If you don't have enough Red Stones, there will be another dialogue informing you to purchase them with EP.

After proceeding, you will receive Red Stones in your inventory. Confirm the following dialogue to complete your upgrading.

Tips: You can only exchange Red Stones for EXP once per day.

2. Exchange Red Stones for Experience with Garrison
If you don't have God's Blessing to enter Offline TG, you can talk with Garrison (Cronus 259,480) for the exchange.

Before you reach level 75, you only need to give him 1 Red Stone a time. However, after level 75, the exchange rules change. 1 Red Stone for the 1st exchange, 2 for the 2nd, 4 for the 3rd, 6 for the 4th and 8 for the 5th. Then the round repeats, 1 for the 6th and 2 for the 7th, and so on.
Tips: You can only exchange Red Stones for EXP once per day.
