Was the seed of the thousand-vine sunflower poisonous?
No, it was not, but it contained very pure energy. The energy was purer than the Level 3 vicious beast meat, and Tang Ling had eaten it unprepared, hence the pain.
It was not a major problem anyway. As Tang Ling cursed Tang Feng for being a sinister person, he endured the pain and gobbled down the whole pot. He then used the eating method that Su Siao taught him and exercised his bowels before he entered the cultivation state.
The magnificent light had set over the mountain before the chill of the night arrived unannounced. The river murmured ceaselessly, and together with the numerous buzzes of the insects, the melody of nature welcomed the Purple Moon.
When the first moonbeam shone on Tang Ling, he finally opened his eyes. The thousand-vine sunflower seeds were really powerful. Even though it was just a pot of soup, he was able to clearly sense the growth in him.
