Lei Refining Room One was on the ninth floor of the Immortal Refining Tower in Border City. When Mo Wuji arrived at the ninth floor, the first cultivation room he saw was Lei Refining Room One.

Sure enough, there was a groove outside the cultivation room for placing jade tokens. Mo Wuji casually inserted the jade token in his hand into the groove, and the heavy stone door of the cultivation room automatically opened.

Mo Wuji entered the stone door, and the stone door closed automatically again.

Mo Wuji roughly observed that this stone room was at least two hundred square meters and about ten meters high. The stone room was empty, with only three handles at the entrance: the first labeled "Start Tempering," the second "Stop Tempering," and the last "Open Door."

Besides these, there were no handles for adjusting the level of lightning source.

Although he had never been tempered in a Lei Refining Room before, it wasn't the first time Mo Wuji had used lightning strikes to temper his meridians. After taking a bottle of Meridian Opening Solution, Mo Wuji directly pulled down the "Start Tempering" handle.

A series of rumbles echoed around the room. After about a dozen breaths, streaks of lightning arcs of varying thickness began to descend. Although the Lei Refining Room was large, Mo Wuji noticed that these lightning arcs only fell within a one-zhang (about 3 meters) radius in the center of the room; no lightning arcs fell anywhere else.

The intensity of the lightning arcs was probably no weaker than what he encountered for the first time in the Thunder Marsh. They struck the one-zhang radius in the center of the stone room with crackling sounds.

Mo Wuji didn't hesitate and stepped directly into the area in the center of the Lei Refining Room where the lightning arcs were striking. Hesitation meant waste; every minute of hesitation was consuming spirit stones.

"Pa pa..." The lightning arcs struck Mo Wuji's body, and streams of scorching heat were guided by Mo Wuji into the meridians within his body.

Only then did Mo Wuji realize the difference between the lightning arcs in this kind of Lei Refining Room and those in the Thunder Marsh or from the Six-Legged Thunder Crocodile. The intensity of each lightning arc here was fixed, making it more suitable for tempering his meridians.

As expected, having money was good. Even in the cultivation world, it was the same.

Before the Undying Mortal Technique completed even a single cycle, Mo Wuji's twenty-eighth meridian was opened.

It was a pity he didn't have spirit stones. If he had spirit stones, Mo Wuji would definitely take this opportunity to cultivate. He wondered what kind of experience it would be to temper his meridians and cultivate at the same time.

Lightning arcs continued to fall, and Mo Wuji continued to consume Meridian Opening Solution. The only advantage of tempering meridians inside the Lei Refining Room was that he didn't have to worry about losing his life. If he couldn't withstand it, he could simply avoid the center of the lightning strikes and rest for a while on the side.

This was a privilege that Mo Wuji didn't have when he was tempering with the Thunder Crocodile or in the Thunder Marsh. To temper his meridians using the Thunder Crocodile, he needed someone to help. Even then, he could be directly killed by the Thunder Crocodile if he wasn't careful. In the Thunder Marsh, it was even more dangerous; no one knew when a strong lightning arc, far surpassing ordinary ones, would suddenly fall. A single one of these strong lightning arcs could easily obliterate a weakling like Mo Wuji, who had just begun cultivating.

In the Lei Refining Room, Mo Wuji was being bombarded by lightning strikes to the point of being almost completely disfigured. This was only because he had taken the opportunity to remove his tattered outer robe and throw it outside the lightning strike zone when the lightning arcs first started falling. Otherwise, he probably wouldn't even have clothes to wear when he left. He hadn't thought to bring a spare set of clothes.

The smell of scorched skin filled the Lei Refining Room. Almost every time a lightning arc struck, Mo Wuji couldn't help but spasm.

Even so, Mo Wuji still didn't choose to leave the lightning strike zone to rest for a moment. One reason was naturally that he didn't want to waste the lightning strikes that were falling for nothing while he was resting; these were all bought with spirit stones. More importantly, Mo Wuji was well aware that while the Lei Refining Room was safe and stable, it lacked the life-or-death pressure.

Yin Qianqian hadn't been wrong about at least one thing: it was difficult for someone who hadn't experienced the line between life and death to become strong. Mo Wuji persevered under these lightning strikes in order to touch his own limits. As long as he hadn't reached the edge of death, he wouldn't easily leave to rest.

Sometimes, willpower was more important than talent. The reason he, Mo Wuji, was where he was today might have something to do with talent. But in Mo Wuji's heart, his willpower was the most crucial factor.

The thirty-third meridian, the thirty-fourth meridian...

Mo Wuji consumed his thirteenth bottle of Meridian Opening Solution and guided four lightning arcs that struck his body into his thirty-sixth meridian.

"Boom!" After these four lightning arcs completely opened his thirty-sixth meridian, Mo Wuji felt a wave of relaxation throughout his entire body. Even though he was now charred black and covered in cracks and wounds caused by the lightning arcs, he felt a sense of sublimation after his thirty-sixth meridian was opened.

This feeling was like the joy and comfort he felt when he advanced from Pulse Opening Stage 3 to Pulse Opening Stage 4, no, it was even more pleasant and fulfilling than advancing to Pulse Opening Stage 4.

Mo Wuji, who had originally planned to take a short break after opening his thirty-sixth meridian, changed his mind after the thirty-sixth meridian was truly opened. He felt incredibly good at the moment, even better than before entering the Lei Refining Room. He decided to use up all of his Meridian Opening Solution before leaving.

After swallowing his fourteenth bottle of Meridian Opening Solution, Mo Wuji suddenly felt a trace of unease because he didn't feel the fiery burning sensation he had felt before after drinking this bottle of Meridian Opening Solution. Apart from a slight burning sensation in his throat, there was no other reaction.

Without any other reaction, he couldn't induce the lightning arcs to temper his meridians and finally open his meridians.

Several lightning arcs fell, and Mo Wuji could only let them strike his body. Apart from physical injuries, he gained nothing.

A bad feeling welled up in his heart. Mo Wuji drank five more bottles of Meridian Opening Solution in succession. Just like before, there was no difference; apart from a slight burning sensation in his throat, his meridians didn't react at all.

The lightning arcs continued to fall. Mo Wuji forcibly circulated the Undying Mortal Technique, guiding the lightning arcs to forcibly strike a possible meridian location.

"Puff!" As soon as the lightning source was guided down, Mo Wuji spat out a mouthful of blood, and his whole body collapsed to the ground, convulsing uncontrollably.

More lightning arcs were about to fall. Mo Wuji struggled to crawl out of the area in the center of the room where the lightning arcs were striking.

The pain of needles piercing into his bone marrow attacked again, and Mo Wuji spat out several more mouthfuls of blood. Fortunately, he had already crawled out of the center of the lightning strikes; otherwise, he would never have been able to crawl out in this lifetime.

The pain and damage caused by forcibly guiding the lightning arcs to strike his body's meridians made it impossible for Mo Wuji to stand up. He lay on the ground, unable to move at all. Although the lightning arcs were still falling constantly and his spirit stones were still being consumed, he had no ability to pull down the "Stop Tempering" handle.

After lying on the ground for more than an hour, Mo Wuji finally recovered a bit of strength. He crawled to the side, took out healing pills from his package, and swallowed several pills in succession.

After swallowing the healing pills and resting for another half hour, Mo Wuji managed to stand up with difficulty. He staggered to the door, pulled down the "Stop Tempering" handle, and then collapsed to the ground.

Wasting spirit stones was secondary. What he was thinking about now was why his Meridian Opening Solution had lost its effect. Could it be that he was only naturally capable of opening thirty-six meridians?

He had long known that true geniuses could open ninety-nine spiritual meridians. Although Mo Wuji didn't know the difference between spiritual meridians (灵络, lingluo) and meridians (脉络, mailuo), he knew that the difference between opening thirty-six meridians and opening thirty-six spiritual meridians was probably not small. In the cultivation world, as long as someone had spiritual roots and could cultivate, opening thirty-six spiritual meridians seemed to be the most ordinary talent.

Almost every cultivator could open at least thirty-six spiritual meridians or more.

A strong sense of unwillingness welled up in Mo Wuji's heart. If he really only had the potential to open thirty-six meridians, then he probably wouldn't even be able to cultivate to the later stages of the Pulse Opening Stage, let alone pursue higher realms.

He didn't know how long had passed when the warning sound of "leaving" rang out in the Lei Refining Room. This meant that Mo Wuji hadn't started cultivating in the Lei Refining Room for a long time, and if he didn't cultivate again, he would have to leave the Lei Refining Room.

Only then did Mo Wuji suddenly wake up from that extreme disappointment. He shuddered, and even felt some lingering fear in his heart. He hadn't felt so disappointed and sad even when he couldn't cultivate. Instead, he had worked hard to find a way to cultivate.

Now that he could cultivate, and was even a cultivator at Pulse Opening Stage 4, he was being defeated by the fact that he could only open thirty-six meridians. This wasn't like him. He had once said, "So what if I have mortal roots? I still won't give up," let alone the fact that he was still a mortal with cultivatable roots.

He had to find new ways to open up meridians. If that really didn't work, then he would follow the original plan and choose to cultivate martial arts, like Yuan Zhenyi.

Thinking of this, Mo Wuji suddenly felt invigorated, and confidence returned to him once again.

So what if I have mortal roots? So what if I have only thirty-six meridians? I just won't give up, I absolutely won't give up.

Even if I really grow old in mediocrity in the end, so what? I was already lucky to survive here. Since that's the case, what do I have to worry about, what do I have to be concerned about?

Mo Wuji regained his composure, got up, put on his tattered outer robe, picked up his package, and opened the stone door of the Lei Refining Room.

There were actually seven or eight people standing outside the Lei Refining Room. A man and a woman were surrounded by the crowd. Mo Wuji recognized the man; he was the handsome young man who had given three spirit stones to the young boy earlier. The beautiful woman was also the one who had always been by his side.

The people outside the Lei Refining Room were stunned by Mo Wuji's appearance. Mo Wuji was charred black all over, his hair was like it had been burned by fire, and wisps of smoke were still rising from his body. The bloodstains on the corners of his mouth and chest mixed with the black ash from the lightning strikes made him look like he had crawled out of a pile of corpses.

The only thing that was out of sync with his overall appearance was his eyes. His eyes were calm and unwavering, as if the whole world had exploded, and he would still be this calm.
