These three long blades were all chain saw blades designed by the master in his early years.
According to the master's design ideas, these three long blades can, at critical moments, activate a motor to make the chain saw blade rotate, achieving the attack effect of the previously repaired [Chain Saw] by Su Yu, greatly enhancing the weapon's damage.
However, there is a downside, which is when encountering Radiation Beasts with scale armor.
Even if the motor is not activated and it's simply used as a regular cold weapon for combat, the chain saw blade's edge would quickly wear out.
In severe cases, the blade might even break during a single battle.
Therefore, later on, every time they venture out for combat, these three fighters always bring spare chain saw blades to replace once they experience wear and tear.
Also, they try to avoid confronting Radiation Beasts with scale armor as much as possible.
But this limits the range Yang Lie's Team originally could hunt even further.
Su Yu, after pondering, came up with his solution.
The master wasn't being lazy when he designed the chain saw blades; he had actually thought it through carefully.
The fighters in Yang Lie's Team are mostly just ordinary people, only eating a bit more Radiation Beast Meat, making their bodies stronger than most.
However, compared to the Radiation Beasts in the wilderness, even those without scale armor are not easy to kill simply relying on cold weapons.
Installing a motor to enhance killing power through blade rotation often increases Yang Lie's Team's hunting efficiency.
It's just that the master was limited by the technical level and couldn't achieve both aspects perfectly.
But Su Yu is different!
He looked at the chain saw blade before him, slightly raised his hand, and removed the blade, his eyes brightening.
His improvement idea is straightforward.
Since the blade can be dismantled, why not go a step further and equip Yang Lie's Team's long weapons so they can switch strategies based on the type of Radiation Beast they battle?
"Use the chain saw blade for Radiation Hyenas and Radiation Giant Ants without scale armor."
"Convert to an Armor-piercing Electric Drill for Radiation Scorpions, Radiation Cockroaches with scale armor!"
Su Yu whispered to himself, and soon, sketched the preliminary design blueprints!
However, when it came to the actual modification.
Su Yu truly realized what it means to have great ambitions but low abilities.
To let a long weapon have multiple applicable ranges involves numerous considerations.
The length of the barrel, the balance of weight, the weight of the spearhead and blades, the motor's installation location, among others...
With Su Yu's current technical level, it's challenging to find this balance.
However, an afternoon's attempt was not in vain.
His Mechanical Affinity, already at level 5, intuitively let Su Yu grasp that if he persisted in his research, he'd find the balance within at most half a month and create the weapon's design blueprint.
Of course, Yang Lie's Team won't actually wait half a month for him in the Sanctuary.
Therefore, Su Yu has another shortcut.
"If I can level up one more time, with a level 6 Mechanic's support, my research efficiency would increase enough that I could complete the blueprints within two or three days!"
Su Yu exhaled deeply, eyes landing once more on the two large boxes of old equipment Yang Lie earlier sent, throwing himself back into repairs!
[You have completed repairing a piece of simple armor. The work difficulty is rated: Simple. You have gained five points of Professional Experience and ten points of skill experience (Basic Mechanical Repair).]
[You have repaired a piece of Basic Armor. The work difficulty is rated: Simple. You have gained ten points of Professional Experience and fifteen points of skill experience (Basic Mechanical Repair).]
[You have completed...]
Soon, it was the morning of the third day.
Su Yu, having stayed up all night, lifted his head, wiped the sweat from his forehead, placed the rare Intermediate Sniper Rifle on the table, screwing in the final bolt of the sighting mirror.
[You have completed a major repair on an Intermediate Firearm. The work difficulty is rated: Extremely Difficult. You have gained three hundred points of Professional Experience and five hundred points of skill experience!]
[Your skill experience is enough. Your professional skill (Basic Mechanical Repair) level has leveled up. Current level: Lv10]
[Congratulations, you have upgraded a professional skill to maximum level, awakening a random Professional Specialization based on the skill's abilities. Drawing... completed!]
[Based on your maxed professional skill (Basic Mechanical Repair), you have gained Professional Specialization (Skilled Mechanic)]
[Professional Specialization: Skilled Mechanic]
[Bonus Effect: Increases efficiency by 20% when repairing, maintaining, or recycling mechanical creations below excellence level, and increases efficiency by 10% when creating or assembling such mechanical creations.]
[Your Professional Experience is sufficient. Your profession (Mechanic) level has leveled up. Current level: Lv6. Professional Core Ability (Mechanical Affinity) level has synchronously increased.]
[Congratulations on successfully learning a new professional skill!]
[Congratulations, you learned: Basic Mechanical Manufacturing (Lv1)]
[Professional Skill: Basic Mechanical Manufacturing]
[Skill Effect: Allows you to attempt assembly of mechanical creations below excellence level without blueprints, consuming parts. Success rate is based on profession and skill levels. Current success rates: Basic Mechanical Creation 30%, Intermediate: 5%, Advanced: 0.1%]
[Note: When possessing blueprints, the success rate increases by one to three times, depending on blueprint quality]
With the final notification sounding.
Su Yu snapped out of the bombardment of lines of prompts.
Looking at his renewed Profession Panel, his eyes were filled with surprise.
"Professional Specialization? And new professional skills?"
Su Yu called up the Profession Panel, carefully browsing the newly unlocked capabilities, feeling increasingly excited.
Let's not even mention the newly opened Professional Specialization.
With this, his repair efficiency can reach a new height.
And for Su Yu, who has a Profession Panel, the higher the repair efficiency, the faster he gains experience.
As for the newfound Professional Skill, [Basic Mechanical Manufacturing], it couldn't have come at a better time!
