After figuring everything out.
Lu Chenxing immediately sought out Lu Changfeng.
"Grandpa Patriarch, I need a batch of artifact-refining materials."
Artifact-refining materials?
Lu Changfeng looked at him, his face full of confusion. "Little Chenxing, are you thinking of trying artifact refining? But your spirit root..."
Everyone knew that spirit roots containing fire and wood attributes suited pill refining, while metal and fire attributes suited artifact refining.
Lu Chenxing had a single-attribute wood spirit root.
Taking up pill refining on the side would be fine.
He could draw on the power of earth fire.
But artifact refining?
Lu Changfeng hesitated rather than agreeing immediately because he feared Lu Chenxing would stray down the wrong path.
With his cultivation aptitude, he had no need to waste time and effort on auxiliary paths.
Focusing on advancing his cultivation realm was the best choice.
Lu Chenxing was no fool, and he had no intention of refining artifacts himself.
"Grandpa Patriarch, I have a use for them."
Lu Changfeng suddenly remembered that this darling grandson before him was a reincarnated mighty cultivator, and he held many secrets.
Many of them might already lie beyond his understanding.
So.
"All right. Since you've asked, Little Chenxing, Grandpa will get them for you."
Seeing Lu Changfeng agree, Lu Chenxing immediately broke into a sweet smile that could almost melt anyone's heart. Then he gave his requirements.
Tier-one spiritual materials.
He also needed successfully refined law artifacts as reference samples.
That would make it easier for Great Xia to research, reproduce, and then mass-produce them.
Then they could be transported back to be sold.
Lu Changfeng immediately had people arrange the purchases.
Half a month later.
Lu Chenxing broke through to the Qi Refining eleventh layer, drawing ever closer to Foundation Establishment.
But something unexpected happened as well.
His cultivation stalled.
Great Xia had exhausted its spirit stones. Without spiritual Qi, cultivation was impossible, and without cultivation, all they could do was stare helplessly.
"They used up all those spirit stones?"
Heavenly spirit roots cultivated quickly, and naturally consumed spirit stones quickly as well.
What was more, four people with heavenly spirit roots were cultivating simultaneously. He had transported quite a few spirit stones back, but even that supply could not withstand such consumption!
So far, the greatest problem Lu Chenxing faced.
Was resources.
The Lu Household was merely a Foundation Establishment force.
Its supply of resources could not be endless.
Sending batch after batch back to Great Xia like this.
How long could it keep that up?
So Lu Chenxing could not count entirely on the Lu Household. He had to find a way to earn resources himself.
He had yet to reach Foundation Establishment, so relying on strength was clearly not feasible.
Great Xia's artifact-refining production chain was the best option.
At his request, Lu Changfeng had purchased large quantities of tier-one artifact-refining materials at an enormous cost.
Had it not been for Lu Chenxing.
He would never have mobilized resources like this.
Once everything was ready, they still had to wait for the passage between the two worlds to open.
Without the slightest progress in his cultivation, he endured an agonizing half month.
Lu Chenxing could hardly wait to transport the batch of artifact-refining materials he had received back, along with tens of thousands of spirit stones he had wheedled out of Lu Changfeng.
Upon receiving this batch of spirit stones, Great Xia immediately resumed cultivation.
They also began establishing an artifact-refining production chain at once.
Based on the artifact-refining theories they had previously researched, they built a secret base.
They gathered every expert in Great Xia whose field had any connection to this area, putting the entire nation's strength into producing and manufacturing law artifacts.
It was just like researching nuclear weapons back in the day.
They spared no effort.
Of course, they had everything they needed when it came to law artifacts.
The samples, relevant knowledge, and other things Lu Chenxing had transported back were very comprehensive.
Great Xia's research progressed very smoothly.
As for the cultivators.
There were four in total, and Zhang Weiguo remained far ahead.
His cultivation had reached the Qi Refining ninth layer.
The other three had identical aptitude, but differences in comprehension led to slight differences in their progress.
Ke Yan, a fire-attribute heavenly spirit root, Qi Refining seventh layer.
Zhou Musen, a wood-attribute heavenly spirit root, Qi Refining sixth layer.
Li Changhong, a metal-attribute heavenly spirit root, Qi Refining sixth layer.
As the four advanced in cultivation, they absorbed spiritual Qi from spirit stones faster, and their consumption of spirit stones increased accordingly.
The tens of thousands of spirit stones Lu Chenxing had sent back this time.
Were actually exhausted in less than a month.
There were still two days until the end of the month, so they could only stop cultivating.
Even without cultivating, they did not sit idle.
Under Ji Chang'an's orders, they assisted with artifact refining, as well as research into pills, talismans, formations, and numerous other auxiliary paths that had yet to be mastered.
With cultivators demonstrating the transformations of spiritual power in real time.
They could see the problems more directly.
The precision machinery of Great Xia's technological civilization could detect, analyze, resolve, and optimize them immediately, accelerating the pace of breakthroughs.
Meanwhile.
Lu Chenxing's cultivation had likewise stalled once again.
He could not help inwardly clicking his tongue.
His earlier vision of a million Great Xia cultivators cultivating simultaneously and providing him with feedback had been wonderful, but in reality, it came with many problems.
The most immediate was resources.
Without resources, even if Great Xia had a million cultivators.
They could only stare helplessly.
Since he needed to receive Great Xia's artifact-refining results, Lu Chenxing would have no opportunity to use the passage to transport spirit stones next month either.
That meant his cultivation would make no progress for the next month and two days.
But there was good news: he had already reached Qi Refining perfection and was about to enter Foundation Establishment.
He immediately shared this good news with the elderly patriarch.
After examining him and confirming it, Lu Changfeng immediately summoned the other two Foundation Establishment cultivators of the Lu Household to gather in the lineage's main hall.
Lu Changfeng, Lu Changgeng, and Lu Xuanming.
The Lu Household's three Foundation Establishment cultivators surrounded Lu Chenxing, staring at him as though he were a monster.
Counting the time.
Eight months.
He was only eight months old.
He was still four months away from turning one.
Qi Refining perfection.
Only a single step away from the Foundation Establishment realm.
"This is too freakish. How long has it even been? Little Chenxing is already about to stand on the same level as us."
"Now this is a truly monstrous heaven's chosen!"
"Patriarch, with Little Chenxing's heavenly spirit root aptitude, a mid-grade Foundation Establishment Pill should guarantee his breakthrough, shouldn't it?"
Lu Changfeng said thoughtfully.
"Let's play it safe and get a high-grade Foundation Establishment Pill!"
The Lu Household already had a mid-grade Foundation Establishment Pill in its treasury.
A high-grade Foundation Establishment Pill would have to be purchased at the market.
This task once again fell to Lu Changgeng.
Thinking of the law artifacts that would soon be delivered, Lu Chenxing hurriedly stopped him, asking him to wait two days before leaving.
Lu Changgeng was going to the market.
He could conveniently take along all the law artifacts refined by Great Xia and sell them.
Part of the proceeds would still be exchanged for artifact-refining materials, while the rest would be exchanged for the resources needed for cultivation.
Lu Chenxing was filled with anticipation.
He wondered how great a surprise Great Xia could bring him.
According to the letter, Great Xia seemed to have mastered artifact refining already, truly living up to its reputation as a world-renowned industrial powerhouse.
They dared to state outright that they had a ninety-nine percent success rate.
Clearly, they were utterly confident.
He hoped that batch of artifact-refining resources would ultimately generate returns several times, a dozen or more times, or even dozens of times their cost.
Then things would really take flight.
Two days amounted to no more than a session of meditation to rest the mind.
They passed in a flash.
Once again, it was the lineage's main hall.
The Lu Household's three Foundation Establishment cultivators and Lu Chenxing made four people.
Lu Chenxing waved his hand, and ripples suddenly spread through the space directly ahead. Then law artifacts emerged one after another, piling up into a small mountain before them.
Beside him.
Three mouths gaped wide.
And remained open for a long time.
