Of course Luo Xiu had space.
They arranged the time for tomorrow, and that evening, Old Jiang had someone deliver the Advanced Golden Lion blood.
The Advanced Golden Lion blood was stored in a white box—not ordinary.
It was a professional liquid nitrogen storage box specially for rare beast materials like organs, blood, and meat.
It released liquid nitrogen at -196C, preserving cells and tissues intact for freshness even after long storage.
A century ago, famous human cryopreservation technology was based on this.
If humans mastered resurrection, bodies stored in liquid nitrogen could be revived with all cells activated.
"However, once the liquid nitrogen box is opened, it must be used within six hours!"
"So you wait to open it until after you comprehend 'Jingdao' (Force Path)!"
Luo Xiu was currently only a Intermediate Warrior, far from comprehending Jingdao.
Beast blood like the Advanced Golden Lion's greatly aided Jingdao cultivation.
Using certain Jingdao manuals, one's strength could become like a lion's—called the "Mad Lion Power."
Combined with Warrior force, it evolved into "Mad Lion Force," with punches amplified by hundreds or even thousands of times.
Jiang Gengyao's Hidden Strength was Golden Mad Lion Hidden Strength, one of the fiercest among Hidden Strength Warriors.
"Wait to synthesize after comprehending Jingdao!"
After safely storing the Golden Lion blood, Luo Xiu started planning tonight's synthesis and tomorrow's schedule.
From tomorrow until the Martial Examination's end, about ten days, Luo Xiu would stay in Imperial Capital.
The Warrior Rookie Camp had a special Martial Examination venue, so Luo Xiu wouldn't need to return to Su City for exams.
"So tonight, I have to synthesize what I can!"
"Eh, if only I had a storage ring like in Xianxia …"
Luo Xiu fantasized.
Ding!
A sudden alert sounded in his mind.
"Huh?"
He looked up and saw the Synthesis Panel before him had completely changed.
Originally two synthesis slots, now there were sixteen—an eightfold increase.
Below every two slots was a small golden box, like the previous Synthesis Panel, but now these sixteen slots formed an enlarged version of the original!
"An upgrade?"
"A Intermediate Synthesis Panel upgrade!"
Luo Xiu remembered that when he upgraded the Mystic Yang Infinity Elixir, the Synthesis Panel had warned that he needed to reach Warrior level to upgrade from basic to Intermediate Synthesis Panel.
Now, the Synthesis Panel in front of him was clearly Intermediate.
"Whoa, such a big change?"
"Sixteen slots?"
"Do all sixteen have to be filled with the same item?"
Luo Xiu thought so, and instinctively placed Power Elixirs in the slots.
After placing two, a golden box lit up.
He then added two more, and another golden box lit up below the first two golden boxes.
"I get it!"
Luo Xiu realized the sixteen slots could synthesize all at once or in pairs, fours, or eights—like a tree structure.
To verify, he placed sixteen Power Elixirs into the slots.
Instantly, the Intermediate Synthesis Panel revealed its full function:
Sixteen synthesis slots, eight golden boxes below them, four below those, and so forth, forming a hierarchical tree, with one large golden synthesis box at the bottom.
Boom!
Before Luo Xiu could react, the largest golden box emitted golden light.
Then a Elixir exuding rich fragrance appeared in the box—none other than the Mystic Yang Infinity Elixir!
"Sixteen Power Elixirs synthesized directly into a top-grade Mystic Yang Infinity Elixir!"
"Unlike the basic Synthesis Panel that required pairwise synthesis…"
"This is so convenient!"
It saved Luo Xiu a huge amount of synthesis time.
Synthesizing two at a time versus all sixteen at once takes very different durations.
"This Intermediate Synthesis Panel retains pairwise synthesis but expands up to sixteen!"
"This upgrade is truly thoughtful!"
Luo Xiu smiled happily but currently had no extra Power Elixirs to synthesize.
He hadn't bought any last time and used all his stock this time.
Luckily, he still had the 12 million Jiang Gengyao transferred plus some savings—buying thousands more Elixirs was no problem.
"Too bad, the Martial Arts Hall only sells a maximum of 1000 Elixirs per transaction!"
Luo Xiu tidied up and prepared to visit the Martial Arts Hall to buy more Elixirs.
He mainly wanted to test whether upgrading the Synthesis Panel allowed upgrading Mystic Yang Infinity Elixir to even better Elixirs.
If so, his strength could soar again.
While preparing to leave, a thought suddenly flashed through Luo Xiu's mind.
"No, what was I thinking before the Synthesis Panel upgrade?"
He vaguely grasped something—the upgrade was related to an idea he'd been pondering.
He had been thinking about one question, but after the upgrade, he momentarily forgot.
Standing at the door, he racked his brain.
Suddenly, he noticed the liquid nitrogen storage box carefully placed in the corner!
"Storage ring!"
"Yes, storage ring! I was just thinking about a storage ring!"
Luo Xiu immediately recalled.
Looking at the empty synthesis slots before him, he suddenly had a possibility in mind:
"What if I don't synthesize but just put things into the Synthesis Panel—would that work?"
