The first realm of Middle Third Grade is the Five Extremes Realm. When a Martial Artist completes the tempering of all five viscera within their body, constructing the bridge for their circulation, they will usher in a full-body Blood Exchange.
This is the first Blood Exchange, the Qi Blood Smoke realm. A Martial Artist can temporarily burn Qi blood to speed up injury recovery in battle, and overall elevate combat power, but the price is substantial.
Using it will inevitably lead to a period of weakness, lasting ten days, months, or even longer, depending on the Martial Artist's physique and Qi blood. If too much Qi blood is consumed, at best it shortens lifespan and leaves hidden injuries, at worst it damages the foundation, even leading to death.
Zhou Qing, who is quite proud, has not yet reached the Qi Blood Smoke realm. Among the five viscera, only three are tempered. However, with the consumption of a Grade-Entering Elixir, he forcefully triggers Blood Burn.
