Dugu Bo's breakthrough had been only natural.
Dugu Bo had decent talent. When he awakened his Martial Soul, he possessed Innate Full Soul Power, and his cultivation speed had been extremely fast. It was only later that the toxins slowed his cultivation progress.
Only after finding the Ice and Fire Yin Yang Well and using it to suppress the toxins within his body had he been able to barely continue cultivating, ultimately becoming a Titled Douluo without really understanding how.
If not for the interference of his innate venom, Dugu Bo would have become a Titled Douluo much earlier, and his strength would have been somewhat greater as well.
No matter what, he would not have been stuck at level 91—a deeply awkward level for a Titled Douluo—for decades.
His innate venom benefited Dugu Bo, but it was impossible for it to benefit him much.
Those deadly toxins had fused with Dugu Bo's Life Force and Soul Power and had become an extremely important part of him. Losing that part entirely would kill him. Yet even if he did not lose it, those uncontrollable toxins would still drag Dugu Bo toward death.
Under normal circumstances, Dugu Bo was not only completely unable to use that power within him, but also had to divide his attention to actively suppress it. Being able to use seventy or eighty percent of his Soul Power in battle was already considered good.
For Dugu Bo, it was entirely a negative effect.
It was like how, from an economic perspective, negative assets were still assets. But in reality, most negative assets were purely liabilities; only a select few people's negative assets could truly count as assets.
Dugu Bo's venom was severely distressed property. Throwing it away would bankrupt him, while holding onto it would slowly bankrupt
