After Jiajia left, Ning Beichen returned to the cave behind the waterfall.
Ning Beichen walked further into the cave, and after about ten minutes, he encountered a dark underground river. Beyond the river, there was no further path.
Without much hesitation, Ning Beichen jumped into the underground river and swam along it. He eventually emerged from the river into a cave that was half-submerged in water.
Indeed, Ning Beichen found a half-rotted wall inside. The wall bore a formation diagram and a broken saber was inserted into it.
Unfortunately, the formation diagram was shattered, and Ning Beichen was unsure if he could still enter.
Ning Beichen tried but found that without the formation diagram, he could not access the dimensional space. He could only regretfully memorize the formation diagram on the broken wall, hoping to repair it in the future.
However, Ning Beichen was not entirely empty-handed. He had found a broken saber. Although broken, its material was extraordinary, and Ning Beichen planned to bring it back for Liu Yilin to study.
Ning Beichen left relatively quickly this time. In less than half a day, he had left the waterfall in the back mountain and returned to Jiajia's house.
Ning Beichen spent another night there. The next day, after helping Jiajia pack her belongings, he left with her.
This time, Ning Beichen did not head directly to his next destination. Instead, he took Jiajia back to Haizhou New City and explained Jiajia's situation to Liu Yilin.
Liu Yilin agreed without hesitation, solving Jiajia's housing problem and using her connections to help her enroll in school. After her education, she could join the group for work.
Ning Beichen also detailed his experiences during this period to Liu Yilin and they discussed various issues together.
Suddenly, Ning Beichen began to understand why his master had asked him to protect Liu Yilin.
A prodigy like Liu Yilin would be a tremendous asset to anyone who possessed her.
Ning Beichen wondered how his master had recognized Liu Yilin's unique qualities.
Recently, besides exploring blessed lands, Ning Beichen had another matter that worried him greatly: his master had not been heard from since his departure, and there was no trace of him.
This was unprecedented. Although his master sometimes left for periods, it was usually for ten days to half a month, and he would never be gone for more than two months.
Yet, his master had been gone for over a year without any news, completely vanished without a trace.
This caused Ning Beichen considerable anxiety, making him restless.
His master was not only his teacher but also his closest kin. His master's prolonged absence suggested he was in trouble, perhaps even in danger.
Ning Beichen and Liu Yilin had discussed his master's disappearance, and they eventually reached a grim conclusion.
It was highly likely that Ning Beichen's master had gone to another dimension or even the Mortal Eradication Realm.
Although Ning Beichen had great confidence in his master's strength, if his master had truly gone to the Mortal Eradication Realm, Ning Beichen's confidence waned considerably.
While Ning Beichen was practically invincible here, he was well aware of his own limitations.
He had only just entered the realm of a Mortal Eradicator. He was unsure of the strength of individuals in the Mortal Eradication Realm, but he was prepared for the worst: anyone from that realm could potentially match him.
This was not an act of self-deprecation but a necessary assessment.
Individuals born in the Mortal Eradication Realm had a significant head start.
Even though Ning Beichen believed that even those born in the Mortal Eradication Realm needed to cultivate diligently and wouldn't be strong from birth.
However, people in the Mortal Eradication Realm were not bound by laws. They did not need to go through the trials of life and death or the Cycle of Heaven to find a way to break through limitations, as Ning Beichen had.
Of course, there was no true fairness in the world. Those with good family backgrounds and advantageous conditions were inherently superior to most.
Consider not just those from the Mortal Eradication Realm, but even people in this world: the children of the wealthy, officials, or celebrities, and even their descendants, born with golden spoons, already had an advantage over ordinary people. How could ordinary people compete?
While you were meticulously planning how to spend ten yuan on a meal, some people were concerned about whether a ten-thousand-yuan dinner tasted good, if a hundred-thousand-yuan handbag was a limited edition, or if a million-yuan car was easy to drive. Even when doing business, they aimed to make at least a hundred million.
So, talking about fairness with them was inherently absurd.
Ning Beichen was not so naive as to believe he was truly superior to people from the Mortal Eradication Realm.
However, worrying about this was futile. What he needed to do now was to diligently improve his cultivation and help those around him do the same. Only by becoming stronger could he handle these troubles.
Afterward, Ning Beichen handed the broken saber to Liu Yilin for her to study its material and composition, and he also gave her the dream beast.
Although this dream beast was not particularly impressive, it was excellent for guarding the house. If an enemy tried to infiltrate stealthily, they would experience the sensation of entering a dream.
However, these were external aids. The most crucial thing was to help Liu Yilin improve her strength, to become a Grandmaster or even a Mortal Eradicator as soon as possible.
Upon his return, Ning Beichen did not leave immediately. Instead, he and Liu Yilin used high-tech methods for alchemy.
Ancient alchemists faced immense challenges, such as requiring extremely high flames and precise control of heat. However, in modern society with its advanced technology, these difficulties were easily overcome.
In this modern era, there were no limits to the intensity of flames, and heat control was simple, managed by computers that could regulate it to the second, giving them a significant advantage over ancient practitioners.
Therefore, the difficulty in alchemy lay only in the formulas and materials, as refining a mature pill required numerous trials and could not be successful on the first attempt.
Initially, Ning Beichen and Liu Yilin focused on refining simple elixirs to accumulate experience. Once they gained sufficient experience, they would proceed to refine those requiring rare heavenly treasures.
About a month later, Ning Beichen and Liu Yilin emerged from the laboratory, clad in dust-free suits, holding numerous pills.
"I never imagined alchemy would consume so much wealth. Fortunately, we have substantial savings, otherwise, even as CEO, I couldn't sustain such expenses."
Emerging, Liu Yilin looked at the bill in her hand and remarked.
