95 Blood Whale's Sac!

Levi had always felt that breathing techniques were magical.

However, this Blood Whale Breathing Technique refreshed his knowledge.

He could increase the number of organs in the human body by cultivating the breathing technique.

This was something that Levi had never expected.

The function of the whale sac was straightforward.

Like the hump, it stores a tremendous amount of energy food produces. Food would be replenished through the whale sac in the human body when it was unavailable.

In Levi's eyes, this was similar to a food bank.

He could eat a lot of food at once. After the digestive system digests the food, the excess energy produced is stored in the whale sac. The upper limit of the storage was related to the cultivation base of knights.

In short, for a low-level knight, if he did not use the breathing technique violently, a full whale sac would output energy to his body and last him a week without any food.
