Otherwise, for a loose cultivator to reach such a level, the difficulty is simply imaginable.
Under such circumstances, with top experts like Lu Changxiao personally imparting teachings, any cultivator present with a bit of comprehension would gain some harvests.
Even though he himself had already reached the Golden Core Grand Perfection Realm, the space for improvement at present was very limited.
However, strong experts like Lu Changxiao have abundant cultivation experience, and his ideas on alchemy are wild and imaginative, making his every word and action extremely valuable experience for any Golden Core Stage cultivator.
In this regard, even if Lin Tianming had limited room for improvement, he would still glean some benefits.
In fact, some of the experiences would be greatly useful when he advances to the Nascent Soul Stage in the future.
Therefore, from any angle, this opportunity is indeed very rare and extremely important.
