Chapter 355: Extraordinary Proficiency - Time Retrospection! (4 more)

January 13th.

Bay Territory, laboratory.

Elder Feld, lying on the experimental platform, gave Matthew a look that said "go ahead, do your best."

The improved anesthetic potion was injected in minute quantities into Elder Feld's body.

He quickly entered a state of numb slumber.

The sharp scalpel gently sliced open the skin, cut through the muscle, and tried to avoid the blood vessels as much as possible.

The main focus of the Second Heart's modification was the blood vessels.

Matthew could "see" that, although the incision was not small, the bleeding was not too heavy.

Hit Points decreased by 2, then stabilized.

Feld was still in a healthy state, the surgery not yet finished, trying to avoid using the Blood Activating Elixir if possible.

Matthew took out a test tube:

"Second Heart, advanced level potion, excellent quality."

"After use, it will strengthen a part of the tissues and blood vessels like a heart, Constitution +1!"
