Capítulo 415: Chapter 415: Yaya's Evolution: What is Gravity? (4 Updates)

According to Matthew's idea, the natural choice was to select new orc and troll test subjects.

Then, he would continue to find some "damn" human criminals.

Their physical condition would reach the level of Bay Domain Soldiers after completing the first and second surgeries.

However, just as Matthew was about to make his move,

an unexpected event occurred, forcing him to halt the continuation of his experiments.

After Yaya learned about the "Extraordinary Specialty - Steel Muscle" from Matthew,

she indulged in a lavish meal costing several hundred thousand Gold Coins and then fell into another deep sleep.

Matthew was somewhat worried about Yaya's state and even donated 500,000 to the Goddess Church to have the "Goddess" take a look at Yaya's condition.

Though Matthew only received a "nothing is wrong" response, it was enough to put his mind at ease.

However, after Mira and Sun Sheng left, Matthew went to Yaya's sleeping den and carefully examined her physical condition.
