Sixth Flesh Tribulation
Wang Wei had already reached the peak of the Third Heaven, so he only needed to focus on his Body-Will Fusion. He had much knowledge of the subject, whether from the Desolate Emperor or Wu Hong, so he took time to ensure perfection in the [Beginning] stage of Body-Will Fusion.
Once he met the standard, he did not hesitate to summon the Sixth Flesh Tribulation. This test could be said to be simple but also challenging. A spinning wheel manifested before Wang Wei, and it released an aura that made his heart palpitate. He did not hesitate and plunged his right hand into the wheel.
A terrifying force broke his body arm apart. The frightening part is Wang Wei did not sense any power similar to True Will, but he knew this wheel could erase his arm from existence without any ability to heal. In other words, if he fails this test, he'll permanently lose his limb. Unless he found some extremely rare and valuable Tier 12 herbs, he'll never be able to regrow it.
