Shelter No. 73 does not have currency, primarily because there is no market circulation, and as for contributions to the Sanctuary, they can only be used personally and cannot be transferred.
Therefore, the trade between the residents of the Sanctuary is mostly bartering.
The two weapons Su Yu traded to Yang Lie were a Chain Saw and a double-range shotgun, which, after repairs, was considered top-tier among Basic Firearms.
What he ultimately received in the trade was a third of the mechanical creations and parts from the next three hunts of Yang Lie's hunting team.
For Su Yu, this price was already quite a substantial return.
In addition, Yang Lie generously gave Su Yu ten boxes of Nutrition Meals as a sweetener, hoping Su Yu would notify him first when similar good items were repaired in the future.
Su Yu naturally did not refuse this.
There was actually a small incident; Yang Lie originally wanted to help his nephew by giving Su Yu five boxes of canned meat he traded from other collection points on the ruins, but Su Yu firmly refused.
The canned meat not produced by the Sanctuary had ingredients of overly complex origin.
It could either be untreated Radiation Beast Meat or even parts of other races or deceased Scavengers.
Yang Lie understood Su Yu's refusal, patted his shoulder, left ten boxes of Nutrition Meals, and then departed with the two weapons. It wasn't long before he returned with a cart.
Mechanical parts and damaged creations — this type of item is collected by every hunting team member to maintain their personal weapons and equipment.
As for a Hunting Team Leader like Yang Lie, his inventory was naturally larger.
He directly delivered three half-person-high large boxes to Su Yu, counting towards the first hunt's share.
Su Yu certainly welcomed it without hesitation.
He moved the three large boxes into his repair shop and, after waving goodbye to Yang Lie and closing the shop door, Su Yu's eyes gleamed as he looked at the three large boxes in front of him!
During the trade, he specifically reminded Yang Lie.
To bring as many damaged weapons as possible, with fewer parts, since his repair shop already had a significant inventory of parts.
The rationale for this is the source of the Mechanic's experience, which Su Yu discovered mainly comes from three activities.
Repairing, recycling, and self-assembling.
Among them, self-assembling weapons yield the most experience, followed by repairing, and finally recycling.
Unfortunately, Su Yu currently did not have many blueprints, and they were mostly basic mechanical weapons.
Assembling one could take half a day, yielding only around a hundred experience points.
In the same amount of time, repairing weapons yields more Professional Experience than assembling weapons, let alone recycling them.
Therefore, without mastering high-level blueprints, focusing on repairing weapons is essential for quick upgrades.
And indeed, Yang Lie responded appropriately.
Two out of the three large boxes were filled with various damaged mechanical creations.
"First, let's start sorting these out!"
The damaged mechanicals retrieved from the ruins mainly fall into five categories.
Close combat weapons like the Chain Saw Su Yu repaired yesterday.
Long-range combat weapons like shotguns.
Then, there are shield-type auxiliary defense weapons, wearable armor-type mechanical protectors, and vehicles.
However, mechanical protectors and damaged vehicles are too rare.
In his three years in the Sanctuary, Su Yu only encountered them once, and only the core mechanics of the Sanctuary were qualified to participate in their repair and recycling.
Obviously, the damaged mechanicals brought by Yang Lie did not include the last two types.
But to Su Yu's surprise, he found two Mechanical Energy Shields in those two large boxes.
However, just as Su Yu was delighted,
With his Mechanical Affinity already enhanced to lv2, Su Yu keenly detected that the core units of these two Mechanical Energy Shields had been completely blown apart.
There was absolutely no possibility for repair.
The shield panel data given by the system subsequently confirmed this.
Seeing the big "Unrepairable" notice, Su Yu sighed.
While knowing that if these Mechanical Energy Shields could be fixed, they wouldn't have been left to gather dust at Yang Lie's home until now before being brought over.
He couldn't help but feel a bit disappointed.
Next, Su Yu discovered a peculiar item he suspected was overlooked.
It was a Metal Disc of unknown construction, looking fairly exquisite overall, which, after wiping, revealed a dark golden sheen.
The disc had unique embossed golden patterns, seemingly imbued with some magic. When one's attention was focused on it, Su Yu found his Spirit involuntarily drawn in, nearly putting him to sleep.
No matter how Su Yu examined it, he couldn't discern the mysteries within the disc.
If it were the past, Su Yu might have assumed it was a part from some special weapon and left it at that.
After all, in this world, Transcendents among humans do exist.
A Physical Body Transcendent like Yang Lie is just one kind; there's another type, with more special, eerie, and mysterious capabilities—the Spirit-based Transcendents.
Their weapons also often have similar mind-bewitching effects; hence, Su Yu wasn't too surprised.
However, this time,
Under the influence of the Mechanic's unique Mechanical Affinity, Su Yu did not discard the small disc.
He somehow felt that inside it, there was something important, but he lacked the technology to unravel it!
"But that's okay."
Su Yu exhaled, his eyes focusing on the two categories of weapons neatly arranged in front of him.
Melee mechanical implements and long-range firearms.
His eyes shone with determination!
"Once I'm done repairing and recycling this batch of weapons, the experience gained should be enough to further upgrade my Mechanic level and core ability, Mechanical Affinity."
"By then, maybe I can unlock the secret of this disc!"
Su Yu sprang into action, raising his hand.
"Nuonuo, let's get to work!"
