Ling Feng's idea was good, but there was a problem: there was a severe shortage of Magic Crystal Warriors!
So far, the core had produced a total of forty Magic Crystal Warriors and eighty Super Warriors, totaling one hundred and twenty units.
All of these were prepared for Yao, who planned to return to her homeland in a month to reclaim her occupied home.
Ling Feng could use these Mechanical Soldiers to enter the underground cave without any problem, but any damage might delay Yao's return journey.
So Ling Feng was very conflicted.
After much thought, he decided to wait, as there was no sign yet that the underground creatures would continue to harass the surface, so there was still time to find a solution.
Leaving two Magic Crystal Warriors on guard here, Ling Feng and the others left Liangdong Village.
After returning to Lingyun Island, Ling Feng went to Gu Li's office.
