Yun Lei's breakthrough to the mid-stage of the Nascent Soul Realm, along with Qing Lei's absence for many years, leaving his cultivation level unknown, placed significant pressure on Li Zhirui. That is why he strove to cultivate every minute he could.
In reality, Li Zhirui's cultivation speed was already extremely fast, but cultivating in the Nascent Soul Realm concerns the Spiritual Soul and requires meticulous attention without the slightest negligence.
Moreover, the Spiritual Soul has a limit to what it can bear. Thus, to break through, one either needs to acquire some rare heavenly or earthly treasure to hasten the process or else proceed to cultivate step by step honestly and earnestly.
Based on Li Zhirui's own calculations, if he could maintain his current pace of cultivation, he would be able to break through within five years.
The question remained whether he would have the peaceful environment necessary for his development in the meantime.
