He nodded. Zheng Jiawu's request was reasonable, and Gu Ran naturally wouldn't refuse.
A Source Energy Stone vein, as of now, was the only stable supply channel for his own Source Energy Stones, and it naturally had to be well-maintained.
Putting all your eggs in one basket was obviously an unwise move, as it left one vulnerable to being choked off at a critical moment.
This simple truth was of course understood by Gu Ran and others, but the problem was that, at present, there was no second force or individual capable of stable output of Source Energy Stones, which made expanding the trade sources an impractical solution in the short term.
Fortunately, whether it was Zheng Jiawu or the power behind him, they were all clear-headed, which relieved Gu Ran.
