But such a practice was not without its disadvantages. As Tang Luo's Sea of Consciousness was repeatedly opened to seal away painful memories, it developed resistance against the Charming Eyes.
In other words, the time and difficulty it took for Yun Xiu to seal these painful memories were increasing.
Initially, it only took a moment, but a month later, it required the time it took an incense stick to burn.
Often, by the time the sealing was complete, Yun Xiu's Spiritual Power would be nearly depleted, necessitating a period of rest and recovery.
According to Tang Luo's judgment, after several more attempts, his body's resistance to the Charming Eyes would surpass the total amount of Spiritual Power within Yun Xiu.
At that point, even if Yun Xiu exhausted all her Spiritual Power, she would be unable to seal his memories of pain; the method, akin to a painkiller, would be rendered useless.
