Explosion rune

They saw a golden piece of paper inside.
Long Chen suddenly waved his hand, and his Spiritual Strength formed a barrier around the two of them as well as the case.
That was an ancient talisman. But because of how long it had existed, it was on the verge of breaking apart. When Guo Ran had opened the case, the talisman had instantly changed color, about to crumble. If Long Chen hadn't summoned a barrier, then a single breeze would have broken it.
"It's eroded, but the design on it is still clear. You should record it. Perhaps it'll be useful," said Long Chen.
Guo Ran examined the rune and was startled. "Boss, this is an explosion rune."
"It's a rune that possesses an immense explosive force. I also have a kind of explosion rune, but its power is limited. However, it seems this rune's tier must be shockingly high. The lines are incomparably complicated. If I used it, perhaps even rank three Celestials would be unable to block it," said Guo Ran excitedly.
