Shen Nanzheng did not doubt Zhao Hai's words. He knew that Zhao Hai cultivated the blood sea god-killing technique, so it was impossible for him to switch to other cultivation techniques. This was because the blood sea god-killing technique was a cultivation technique that could be cultivated from the Dharma reserve realm all the way to the divine Dharma realm. However, if one were to switch to other cultivation techniques, it would be extremely difficult for them to cultivate to the Dharma cultivation realm in their entire life. Hence, ordinary people would not cultivate the blood sea god-killing technique.
