Explosive Mechanic had four forms and five levels.


    The four forms were Laser Cannon, Flying Bullet Cannon, Lightning Cannon, and Light Blade Cannon.


    The five levels were weak, normal, tough, good, and elite.


    It was a weak grade. Without the blueprint, it lost its position. Now that it has upgraded to a normal grade, Ye Zhongming looked at its stats.


    “Attack form 1, Laser Cannon (unlocked), two units of energy needed (level 2, number of attacks 5, strength 100 PA, range 100 meters. Fire rate 0.1/second.)”


    “Attack form 2, Flying Bullet Cannon (unlocked), 15 units of energy needed (level 2, number of attacks 10, strength 80 PA, range 200 meters. Fire rate 1/second.)”


    “Attack form 3, Lightning Cannon (unlocked), 80 units of energy needed (level 2, number of attacks 5, strength 200 PA, range 80 meters, area covered 50m^2. Fire rate 0.2/second.)”


    “Attack form 4, Light Blade Cannon (unlocked), 900 units of energy needed (level 2, number of attacks 3, strength 350 PA, range 300 meters, area covered 70 m^2. Fire rate 0.1/second.)”


    “Use two forms at most each time. Cooldown time: 10 hours for one form, 15 hours for two forms.”


    “Durability: 1000, launch time follows durability. Inject energy to repair durability. 1 durability= 100 units of energy.”


    Facing such data, Ye Zhongming’s heart jumped.


    As compared to the previous explosive mechanic, the four states changed.


    First was the level. Its attack level became level two. This fits the normal grade.


    The level increased, and so did the strength. He didn’t understand what PA meant, but it didn’t stop him from comparing it to the previous value.


    The 50 PA attack for four terrified the level seven Neal. Now that it reached 350 PA, it would threaten a level eight lifeform. It might even be able to hurt a level-nine lifeform.


    The three differences were required energy, attack range, and fire rate. This was an all-rounded upgrade.


    This meant that he had to use more sacrifices.


    Finally, the upgrade notification spread again. It went from a normal grade to Tough Grade!


    “Attack form 1, Laser Cannon (unlocked), three units of energy needed (level 3, number of attacks 10, strength 150 PA, range 100 meters. Fire rate 0.1/second.)”


    “Attack form 2, Flying Bullet Cannon (unlocked), 20 units of energy needed (level 3, number of attacks 15, strength 110 PA, range 200 meters. Fire rate 1/second.)”


    “Attack form 3, Lightning Cannon (unlocked), 120 units of energy needed (level 3, number of attacks 5, strength 250 PA, range 90 meters, area covered 80m^2. Fire rate 0.2/second.)”


    “Attack form 4, Light Blade Cannon (unlocked), 800 units of energy needed (level 3, number of attacks 3, strength 450 PA, range 350 meters, area covered 100 m^2. Fire rate 0.1/second.)”


    “You can use three forms at one time. Cooldown time, one form 7 hours, two forms12 hours, three forms 20 hours.”


    “Durability: 2000. When firing, consume durability. To recover durability, inject energy. 1 durability= 100 units of energy.”


    The Tough Grade Explosive Mechanic’s strongest attack reached 450 PA. Ye Zhongming was pleased. He was also happy with the other aspects.


    But like before, he faced a choice. Should he continue?


    Ye Zhongming hesitated longer as he found it tough to make the choice.


    Finally, the gambling nature in his bones exploded. He decided to continue!


    He tossed more items in. The energy was amassed, and he started to upgrade.


    Until... He heard a delightful notification.


    “Upgrade success, Tough Grade Explosive Mechanic upgraded to good grade!”No?v(el)B\\jnn
