“Uh…” Lin Xiao nodded somewhat awkwardly, saying, “These two prescriptions are both for refining Invisibility Pills. If we have the ingredients for one of them, it could be useful for our operation this time. Moreover, this pill formula can also be given to the Zi family.”
“Invisibility Pills?” Upon hearing this, Zi Huang was startled.
He had heard of Invisibility Pills, which could make one’s figure disappear, proving quite useful for many operations.
In combat, they could play a significant role, and at the very least, they could be used to escape.
Of course, for someone at the Martial Emperor level, low-grade Invisibility Pills wouldn’t be of much use.
But for the Zi family members below the Martial Emperor realm, they would be immensely valuable. Such a pill formula was obviously extremely rare and precious.
To think that Lin Xiao not only possessed such a formula but had two of them.
And he was casually offering to give it to him.
It seemed that Lin Xiao’s background was likely not simple.
“Just write it down, and I’ll send people to find the ingredients,” Zi Huang promptly nodded in agreement, clearly intrigued by the Invisibility Pill formula.
Lin Xiao nodded, then took out pen and ink to write down the prescriptions, along with a separate copy of the pill formula and refining method.
To be precise, there were two formulas for Invisibility Pills of different grades.
Naturally, the higher the grade, the better. However, to account for the possibility that the Zi family might not have the corresponding ingredients, Lin Xiao wrote down both.
After all, the ingredients for Invisibility Pills were extremely rare. Even with two formulas, Lin Xiao wasn’t confident the Zi family could gather all the materials for either one.
Still, since Zi Ling was the Zi family’s spirit controller, giving the formula to the Zi family was akin to giving it to Zi Ling. There was no harm in giving it away, and it could also earn Zi Huang’s favour.
Afterwards, Lin Xiao and the other person left the Zi family’s main hall.
As Zi Huang had instructed Ling Hu not to open the jade bottle in front of others and to refine it immediately upon opening, Lin Xiao didn’t get to see what was inside Ling Hu’s black jade bottle.
Soon, Ling Hu went alone to a room to refine it.
Lin Xiao returned to his own room. Half an hour later, Zi Ling hurriedly arrived and poured out a large pile of stones from her storage ring.
Looking at these stones, Lin Xiao’s face darkened. They were indeed from the Zi family, dazzling and varied, appearing rather “special.”
However, the quality of these stones wasn’t high and likely wouldn’t be of much use for cultivating his Heaven-Sealing Stone Hand.
“I’ll take them for now,” Lin Xiao said, somewhat speechless, waving his hand to store the stones in his storage ring.
“Uh, not very useful?” Zi Ling paused, saying awkwardly.
Lin Xiao nodded honestly.
“The Zi family’s special stones are just those…” Zi Ling said, then took out a thumb-sized fruit from her storage ring. The fruit was extremely hard, entirely white, and octagonal in shape.
As soon as it was taken out, an intense cold aura emanated from the octagonal fruit.
“This is… an Icy Octagon?” Lin Xiao exclaimed, his eyes lighting up.
The Icy Octagon was a fruit borne by a short herb growing in extremely cold regions. The plant took ten years to grow, one year to flower, and a hundred years to bear fruit.
In other words, an Icy Octagon took over a hundred years to mature. Once it did, it would absorb all the yin-cold energy within a hundred-mile radius.
The Icy Octagon primarily had a high degree of cold attributes, with fewer yin attributes.
Still, it would undoubtedly be of great use to the Blue Corpse Puppet.
“This thing is quite extraordinary. It’s been in our Zi family for some time, but we didn’t know its use. You recognise it?” Zi Ling asked curiously.
“It’s a fruit grown in extremely cold regions. For most people, it’s indeed not very useful unless they have a yin-cold attribute talent. But for the Blue Corpse Puppet, it’s highly valuable,” Lin Xiao replied.
“Well, that’s good. It wasn’t much use to me anyway,” Zi Ling said, quietly relieved.
“…”
Lin Xiao was speechless. If it had been useful, would she have taken it back?
“Refining this Icy Octagon will likely take some time. Let’s have the Blue Corpse Puppet refine it now.”
With that, Lin Xiao took out the Blue Corpse Puppet, gave the command, and inserted the Icy Octagon into its mouth. A faint cold aura began to emanate from the puppet’s body.
“It seems there’s real hope for a breakthrough through refining,” Lin Xiao nodded to himself.
Looking at the motionless Blue Corpse Puppet for a moment, Zi Ling said, “By the way, I’ve received the Invisibility Pill formula. If we find the ingredients, I’ll send them to you right away.”
Lin Xiao nodded. After Zi Ling left, he sat cross-legged in a corner some distance from the Blue Corpse Puppet and took out the pile of stones again.
“Although these stones aren’t of high quality, they have some unique properties. No need to waste them.” Lin Xiao slowly closed his eyes, circulating the Heaven-Sealing Stone Hand technique and beginning to refine the pile of stones.
Though the stones weren’t of high quality, they were equivalent to refining half a regular stone mountain. They would suffice for cultivating for a short while.
Half an hour later, Lin Xiao had almost finished refining the pile of stones.
But when he was halfway through refining a fist-sized, oddly shaped grey stone, he suddenly discovered another black stone hidden inside it.
This black stone, only half the size of a fist and irregularly round, felt different from the previous stones after refining.
As he refined it, a vast, ocean-like surge of stone energy poured into his hand sea.
“This is… high-quality stone?” Lin Xiao was shocked.
He hadn’t seen this type of stone before, but refining it instantly revealed its exceptional quality, comparable to Heavy Mountain Strange Rock, if not of a higher grade.
“A stone within a stone. This stone’s origin is likely not simple. It seems I underestimated it.”
Lin Xiao sighed, a surge of joy rising in his heart. This time, he had stumbled upon a treasure.
Immediately, Lin Xiao closed his eyes and focused on refining the black stone. Waves of stone energy continuously poured into his hand sea, tempering it.
…
Half a month passed in the blink of an eye. During this time, Lin Xiao had been refining the special black stone.
His hand sea progressed rapidly, advancing from the equivalent of a third-level Martial Venerable’s cultivation to a fourth-level, then to a fifth-level, and finally, upon completing the refining, to a sixth-level Martial Venerable.
Jumping three levels of Martial Venerable in one go filled Lin Xiao with unexpected joy.
“The petrifying power is roughly equivalent to my elemental force. With sixth-level Martial Venerable petrifying power, fifth-level Martial Venerable elemental force, and mid-tier fifth-grade spiritual power, I could probably hold my own against a first-level Martial Monarch.”
Slowly opening his eyes, Lin Xiao muttered to himself with delight. But as he came to his senses, he suddenly felt a chill and quickly glanced at the Blue Corpse Puppet nearby.
