The next day, Qiao Long submitted the list of applicants for Black Medicine advancement to Ono Shinsyo.
It was approved immediately, with the date set for three days later—the ninth.
During those few days, Gaoxin did not train. Instead, he studied his abilities.
Ever since he exchanged for B-grade High-Energy Digestive Bacteria, his eating efficiency had increased tremendously.
Ordinary food basically began breaking down the moment it entered his stomach.
Besides his intestines, his stomach and even his esophagus had been occupied by that colony of bacteria. They could also secrete entirely new high-energy gastric acid, increasing his digestion speed.
However, this placed a tremendous burden on Gaoxin's body.
His stomach and intestines often ached faintly. Clearly, even he could not endure the gastric acid produced by this bacterial colony.
Fortunately, the bacteria would not kill their own host.
When they noticed that their living environment was beginning to deteriorate, they proactively lowered the concentration of their digestive acid, keeping it at a level Gaoxin could barely endure.
In fact, because Gaoxin's stomach was constantly damaged and inflamed,
the high-energy bacteria even proactively adjusted their "synthesis tendency." After Gaoxin ate, they would primarily secrete high-quality proteins and nutrients that aided the body's healing.
And this was merely their instinctive response toward their symbiotic host.
Gaoxin tried it out. If he had an urgent, powerful enough desire, he seemed to be able to communicate with the bacteria, ordering them to adjust their decomposition tendencies.
For example, when Gaoxin wanted to heal, he could order the bacteria to maximize their tendency to synthesize the nutrients required for the human body's self-healing.
When Gaoxin wanted to train, he could order the bacteria to maximize their tendency to synthesize the nutrients required for human growth.
When Gaoxin wanted to fight, he could order the
