"This spear." Wu Han walked up to the first weapon. With a single glance and a touch of his divine-level sense, he already understood its nature.
"Made from the fang of a Spirit Serpent, roughly at the seventh stage of Qi Condensation. The venom was potent, it seeped into the fang itself, still toxic even now. You carved it with too much force, though. Still, good quality work."
"Correct." Rong nodded. It was expected of a disciple of a doctor to recognize something poisonous.
"The second one," Wu Han continued, moving to the next spear, "is made from pure silver. That keeps it light, but you reinforced the tip with Cold Steel to harden it. It lost most of its Yin property, but now it's both light and durable."
"You've got sharp eyes." Rong's voice held a note of grudging respect.
Not many could tell pure silver from cold-steel alloy, the colors were nearly identical. Some merchants even scammed buyers by selling silver and calling it cold steel.
"And this one…" Wu Han stopped at the last spear, a pitch-black weapon that reflected light like polished glass. His expression didn't change, but his silence made Rong chuckle.
She crossed her arms, confident. The boy would never know this one. The material didn't even exist in their entire Azure River Country.
Wu Han's eyes widened. He reached out and lifted the weapon, nearly stumbling from its sheer weight.
"Done already?" Rong smirked, eager to collect her win. Oh, she was going to enjoy ordering the Miracle Doctor's disciple around, even if she hadn't decided how yet.
"Obsidian…" Wu Han's calm voice froze her where she stood.
He turned the spear over, studying its reflection and craftsmanship, then laughed softly.
"You actually made a spear out of obsidian?"
"You— how did you?" Rong was speechless.
Obsidian was said to come from volcanoes.
She'd heard of it from a traveling merchant, a woman who'd crossed two continents before selling her a single shard of the rare material.
Only a few people in the entire country possessed it.
"I found some in my master's bag," Wu Han lied smoothly. "He uses one as a surgical knife."
It wasn't true, of course.
He'd never seen or heard of obsidian in any of the minds he'd absorbed. This one, he recognized only from his own world, a guess, but an educated one.
But really, a spear? He almost laughed outright.
Yes, it was sharp, yes, it looked magnificent, but obsidian was one of the worst materials for a weapon.
It would shatter the moment it struck something solid.
Still, the tip wasn't what interested him most.
Before Wu Han could respond, Rong blurted out, "I'm not trying to cheat you, alright? I don't even know what that pole's made of."
She didn't dare contradict Wu Han if he made a guess, she didn't even know the truth herself, and saying anything wrong might offend his master.
"That means I got all three right, didn't I?" Wu Han asked, slipping the spears into his bag with an easy motion.
"Yes, yes… ah, damn it." Rong rubbed her temples, realizing what she'd just admitted. "Did I just get hustled?" She let out a long sigh. "Alright, kid. What do you want?"
She'd underestimated the knowledge of the Miracle Doctor's disciple and got played for it. But she was a woman of honor, a deal was a deal.
Wu Han smiled and pulled out various materials from his ring: rare woods, refined metals, even some spirit ores.
"Whoa…" Rong's eyes widened, her face lighting up with joy.
For a blacksmith, it was a dream, enough material to craft masterpieces. Ideas spun through her head so fast she almost forgot to breathe.
"What kind of spear are we talking about? The best I can forge from all this, or something specific?" she asked, already guessing the answer.
The boy's calm gaze told her enough.
He wasn't just rich; he was sharp. There was no way he'd come here without a design in mind.
Wu Han smirked. "I want you to craft me a spear that can withstand this level of damage."
He waved his hand, and from his storage ring floated out the ruined spear from his battle with the Iron-Scaled Thunder Wolf.
Once a fine weapon, it was now just a melted chunk of twisted metal, a pole with a shattered tip, burned black from lightning.
Rong's expression hardened. She examined the remains carefully, her eyes narrowing with professional focus. When she spoke again, her tone was serious.
"I'm going to need more than a favor to make this work. Two hundred spirit stones. That's my price. Normally, I wouldn't even accept an order of this magnitude."
The job would take weeks of nonstop work, leaving her unable to handle any other commissions. It was risky as a business move, but for a blacksmith, also very tempting.
"Sure." Wu Han pulled out another two hundred spirit stones from his ring, making her blink in disbelief.
"How rich is your master, really?" she muttered. Spending three hundred and fifty stones on four spears was either insanity or proof his master had deep pockets.
"He likes to say kindness doesn't need a price," Wu Han said, fabricating the lie smoothly. "Still, he earned plenty anyway, so he gave some to me."
He even managed to look grateful while talking about his own alternate self. The audacity.
"Haha! Fine," Rong laughed, shaking her head. "If it's done and I can't find you, I'll deliver it to the Luo Clan myself."
"That'd be a pleasure," Wu Han said with a faint smile. "But I'd rather come and pick it up myself."
"Works for me." Rong didn't mind at all. She was already eager to start.
Maybe she'd get chewed out for delaying other orders, but who would dare complain about someone taking a commission from the Miracle Doctor's disciple?
After securing his new weapon order, Wu Han stepped out of the store.
He summoned the obsidian spear and looked at it with a smile, almost a laugh.
The handle hadn't reached full purity yet, but since it was black, she must have made an educated guess and forged the parts together simply because they matched in color.
Unknown to her, that guess was a mistake.
Even if she had realized it, she wouldn't have been able to make proper use of it anyway.
Because the identity of the material used for the shaft was—
Tungsten.
