Result

Thankfully, he got to skip one of the hardest parts of integrating poisons into one's body, which was general resistance. Because he needed the poison to work, he couldn't gain general immunity or resistance against it.

Thus, his training time was greatly shortened due to the removal of this step.

Despite that, it took quite some time. Mastering poison techniques took longer than he expected because of the time it took to master a new poison technique because not only did the technique surrounding them need to be mastered, but the poison itself took time to be integrated into the body.

With normal Martial Art techniques, only the technique itself required mastering. It canceled out with the reduction in training time that Rui got by skipping a step.

In the end, it was only four months later that he finally mastered the poison as well as the technique that allowed him to deploy the poison into his own body when he needed to.
