"52 million..." Li Ming let out a long breath, the metal energy storage balance reaching a new high.
Originally he had over 9 million left, this time he extracted 43 million, and according to the price comparison, it was a slight loss.
However, it saved time and energy, and he was about to enter the old lair of the Torch Organization; obtaining such a large amount of metal energy beforehand allowed him to feel much relieved.
"Hmm... It's just the right time to upgrade." Li Ming had already planned for many days and did not hesitate; one tall and one short figure stepped out from both sides of his body, respectively the Thunderbolt Guard and Taipo.
These two mechanical guards needed 20 million metal energy for a total upgrade, each equivalent to a top-tier A-Level Controlled Object.
Previously, due to insufficient accumulation, it had been put off.
But he hadn't forgotten that the benefits of upgrading the guards were quite substantial.
