章 421: Chapter 419: Give an inch and take a mile_1

"The Fourth Grade Thunder Sound Sword can stimulate sword qi thunder sound, which has a strong restraining effect on Demon Envoys and Evil Cultivators,"

Lu Xuan muttered to himself in his heart while looking at the silver-white short sword in his hand.

In his eyes, this Thunder Sound Sword was much stronger than the Fish Dragon Sword he encountered earlier. It naturally carried the special sword qi thunder sound, which has a miraculous effect when facing Evil Cultivators and Demon Envoys.

More importantly, according to Lu Xuan's speculation, this Fourth Grade Thunder Sound Sword harboring Buddhist Power might be able to cultivate the Diamond Bodhi Spirit Plant.

The Diamond Bodhi is currently placed in that Incomplete Secret Realm. Since only the Soul Guidance Zen Incense can slightly promote the growth of the Spirit Plant, the Bodhi Spirit Seeds have not shown much change.

Now, with this Fourth Grade Thunder Sound Sword, the Spirit Seeds might sprout and grow roots.
