Chương 337: Breaking Through the Mid-Level Aperture Tempering Realm

Inside the secluded chamber of the Primordial Sword Sect, the formations around the courtyard had already been activated.

Chen Fei sat cross-legged, circulating his elemental energy within his body. The thirty-six acupoints in his body were resonating with each other, and this resonance was constantly growing stronger.

The thirty-sixth acupoint had only been opened for a few days, and at Chen Fei's current cultivation speed, it would take at least a month to fully fill it with elemental energy.

However, over the past few days, as the synergy between the acupoints continued to strengthen, the newly opened acupoint was absorbing elemental energy at an accelerating rate, increasing at an astonishing speed.

"Begin!"

Chen Fei's eyes suddenly opened wide, and his Zhongyuan Sword Art surged to its limits. The method of breaking through was surging within him, causing the thirty-six acupoints to tremble slightly.
