Chu Mu left the Trading place Hall and walked into the plaza.
There were hundreds of people coming and going in the plaza, and Chu Mu immediately used his Soul Sense to search for Chu Ning and Chu Xing.
Back then, Chu Ning and Chu Xing followed Chu Mu to the Sin-Origin Mountain range, where they acquired millions of gold coins. At the time, with Chu Ning and Chu Xing's level, those millions of gold coins were absolutely enough to significantly increase their strength.
Soul Pet Masters often need to make leaps in their abilities. Once they cross a certain threshold, their strength will snowball and continue to grow.
Chu Mu believed that Chu Xing and Chu Ning were not mediocre talents; they just never had an appropriate opportunity to become stronger. After that incident, their strength should have undoubtedly improved, and coming to World City would be the best proof!
