After Connor found three medicinal herbs in the Precipice Cave, he asked Diana to pluck them and pack them up.
After all, Connor had risked his life to find these three herbs.
Moreover, even if Connor left the herbs here, they would be snatched away by others then, so it was better for Connor to take them himself.
According to what Diana said, these three herbs were all priceless. More importantly, these rare herbs couldn't be bought with money.
After knowing that these medicinal herbs were precious, Connor felt more or less at ease. After all, he had spent much effort finding these medicinal herbs. This should be considered a comfort to Connor.
Either way, Connor's trip to Medicine Kings' Valley was not in vain!
After obtaining the medicinal herbs, Connor did not plan to stay in the Precipice Cave for long. Thus, Connor had Timothy and the others guide them out of Mount Dragon.
