"If they keep growing, they might disturb the current cultivation civilization, leading to infighting and weakening the entire Myriad Emperor World."
"A battle between Science & Technology and Cultivation?" added Wang Wei with shining eyes. "That would be an interesting sight to see."
If it were before, Wang Wei might be sure cultivation would win. However, after seeing the development of the Science and Technology World and the Quantum Realm, he was not so sure.
"Who do you think would win?" asked Wu Hong, also intrigued by the notion.
