As long as Li Fan's No Extreme Nascent Soul was formed, the Zhenyang Fire could explode in growth. Once enough genuine energy was accumulated from harvesting energy in the Taisu Realm in the future, Li Fan would even have to constantly be mindful of his Dao heart, lest an outburst of emotion ignite the sun and cause the fire to backfire, consuming heaven and earth.
The new cultivational method of the observatory master was, after all, different from the sequence taught by the technique, and he did not possess the Taisu Dao Body's "fuel," so his Zhenyang Qi was too fierce, and the fuel was insufficient. He could not spontaneously combust like Li Fan; instead, he had to constantly feed the fire with more fuel, harvesting Zhenyang Fire seeds every few days, just to keep the true fire alive.
