To be able to upgrade a vehicle to the second star, instead of the original 100 kg of steel, 50 kg of aluminum, and 10,000 level 5 rank O mutation crystals, all that Henry required at this point was three level one bronze rank mutation crystals.
Since that was the case, Henry did not hesitate to begin the upgrade. He upgraded every vehicle that he had upgraded previously to the first star, increasing and making sure that they had already reached the second star.
Of course, there was no way that he was going to allow the ordinary vehicles that he had upgraded to be at the same level as the vehicles that the core members of the territory possessed.
So, he went ahead and upgraded The attack system together with the defensive system of the vehicles. For that reason, he spent yet another five level four mutation crystals for each vehicle to improve the attack system, before spending yet another for the defensive system.
