A deal

Wang Yuelin did not want to believe Mo Qiang but the latter seemed too confident to ignore which was why he pursed his lips and then said in a soft voice, " If you can help me revive these bees then I will give you the queen egg as well as a few slaves one." 

These eggs were left behind by his grandparents who once worked as magma bees keeper but then they were attacked by the hunter and could only freeze these eggs and hide them as for the magma bees which were being raised by his grandparents were all killed as their stinger and wings could be used to make antidotes for many poisons. 

Ever since then Wang Yuelin and his father had been frantically trying to revive these magma bees but despite their fanatic attempts, the research was still where it was years ago. If Mo Qiang was telling the truth, then it meant that she might have developed a potion or fertilizer that can be used to grow trees even in this toxic environment.
