章 308: Yin-Yang Spirit Concentration Technique, a Terrifying Upgrade

The five shiny gift bags were so beautiful and dazzling in Su Yi's eyes. However, the price had gone up a little too much, right?

He looked at the price of each gift bag that was more than 300 spirit stones. If converted into money, this would be worth 300,000 yuan.

However, he was not disappointed. After all, almost all of these gift bags were things that could not be bought even with spirit stones. Take the immortal-grade mental cultivation technique and immortal-grade spell method among the two gift bags as an example. If these two things were added together, they would probably be priceless.
