Lin Yang took in every shift of expression on Dugu Bo's face.
He could more or less guess what Old Poison was thinking.
Extreme Poison... was not entirely impossible.
After all, that Snow-Colored Swan Kiss was still growing at the Ice and Fire Yin Yang Well.
The Snow-Colored Swan Kiss was an extremely unusual immortal herb. It contained no toxins itself, yet it was known as the "grass of deadly poison."
That was because it could amplify toxins hundreds or thousands of times. Even the slightest trace of poison would become lethal under its effects.
In theory, simply having Old Poison eat the Snow-Colored Swan Kiss would allow him to attain extreme poison.
The problem was that no one could withstand such terrifying toxins.
But if he could condense a poison-attribute Soul Core while also controlling the effects of the Snow-Colored Swan Kiss, the two-pronged approach might work.
Of course, Dugu Bo already had a Pill Pearl.
But a Pill Pearl was a Pill Pearl. Ultimately, it was different from a Soul Core, and its effects were weaker as well.
Trying to use a Pill Pearl to contain extreme poison would be courting death.
Lin Yang did not voice any of these thoughts.
It was not that he distrusted him, but that he feared he would chase quick results.
The Soul Core Method would become commonplace in later generations, but no one in this era had tried it yet. If he attempted it rashly, it would be too late for regrets.
After his Nichirin Blade martial soul awakened extreme gold, Lin Yang could clearly feel that his cultivation had slowed considerably, though it remained within an acceptable range.
After all, his Sun Breathing operated without interruption every day. Little by little, it added up to a very substantial accumulation.
