The driver laughed, "Young man, you have a good sense of humor. Why would you need brightness on such a gloomy day?" With a screech of brakes, he added, "Alright, this is where I drop you off. That's Old Bald Mountain ahead, and the Turtle Stone is right on the peak. The entire mountain is a graveyard. I’m already taking a big risk bringing you out here this late; otherwise, no one would dare use this road."

Zhou Huan leaned out to look ahead, then pulled out a large bill and said, "Big brother, thank you for your dishonesty. Take this money and have a safe trip."

The truth was, before getting in, Zhou Huan had agreed with the driver to be dropped off at the foot of the mountain. However, the man stopped about a kilometer shy of the base. Zhou Huan wasn't a fool, so he decided to play a trick on the driver to teach him a lesson about keeping his word—he handed him a massive bill worth two billion from the Underworld currency.

The driver took the money Zhou Huan offered, stuffing it into his pocket without even looking. Then, he pulled out his own wallet and casually handed Zhou Huan a paper note.

Zhou Huan stared intently and instinctively took two steps back. In his hand was a colossal bill worth one and a half billion from the Heaven and Earth Bank.

"Brother, I’m not short on cash. Go ahead and spend that well. However, you still owe me some Renminbi. This Underworld money is only good for burning offerings on the mountain; it's useless right now. Why would you try to pay for a cab ride with that? Are you looking for trouble?" The driver’s tone was sharp, which instantly angered Hong Kun. Hong Kun raised his hand, intending to yank the driver out of the car. But as soon as Hong Kun opened the door, he immediately froze, both hands raised.

"Driver, what are you trying to do?" Hong Kun panicked. He had intended to hit the man, but instead, he’d been cornered. The driver had a gun pressed against Hong Kun’s head.

With a cigarette dangling from his lips and the gun firmly in hand, the driver forced Hong Kun while yelling at Zhou Huan, "Listen up, young masters, don't try any of your weird tricks with me. I saw your type yesterday. You can ask around—who runs this route in the taxi business? You try to cheat me, and when that fails, you try violence, is that it?"

The corner of Zhou Huan’s mouth quirked up. "It seems you truly are a man, a genuine man. Fine, I’ll give you Renminbi." Zhou Huan casually tossed a crisp hundred-yuan note to the taxi driver. As the driver reached for the red bill, Zhou Huan’s movements were astonishingly fast. He delivered a heavy punch straight to the driver’s face, followed by a kick. The driver crumpled to the ground, instinctively raising the gun to aim at Zhou Huan.

"Young master, stop right there! Aren't you afraid I'll blow you away today?" The driver, now on the ground, was visibly frantic.

Zhou Huan leisurely approached the driver, squatted down, and slowly reached out to grip the gun in the man's hand. He slowly raised it, examined it closely, and remarked, "Brother, the quality of this gun is terrible. Have you ever seen a real firearm without proper sights?"

As soon as Zhou Huan finished speaking, small beads of sweat dotted his forehead. The driver looked at him with a panicked, helpless gaze. "How are your eyes so sharp? Who are you?"

"It doesn't matter who I am. I only ask you one thing: your actions tonight seem rehearsed. Has someone settled a score with you recently?" Zhou Huan pressed.

The driver let out a long breath and sat cross-legged on the ground. "Sigh, I won't lie to you. This huge fifteen-hundred-million bill was also given to me by someone else, maybe yesterday. A person with their head completely covered, mumbling when they spoke. Why cover your head in broad daylight? When they got out, they handed me this kind of money. But what’s strange is that the fellow ran incredibly fast; before I could react, he was gone. So, I learned my lesson. When I picked up your fare tonight, even though it was late, I brought this toy gun just to give myself courage."

The driver's story brought a laugh from Zhou Huan. Hong Kun, who had been thoroughly frightened, also started chuckling, stepping closer. "Big brother, I give up. You really put on a convincing performance; you almost fooled me."

"Alright, driver, here’s another two hundred. Tell me clearly what the person you drove yesterday looked like or any distinguishing features?" Zhou Huan asked. The driver sat on the ground, thinking for a moment, then recounted the details. Zhou Huan’s first reaction was to secretly bless that scoundrel. He then asked the driver, "Where did you take him yesterday?"

"To the Howk & Lake Business Hotel. But now that I think about it, I’ve driven him there more than once," the driver recalled.

Zhou Huan thanked him politely. "Thank you, master. Keep the money. We still have to go up the mountain, so you should leave first. Just leave me one of your business cards; if anything about that person comes up, I’ll ask you, and you certainly won't miss out on any benefits."

"That sounds great, thank you, brother—you are a pure man!" The driver was ecstatic, hopped back into his car, honked twice as a sign of respect, and then sped off.

"Master, he still owes us a kilometer of the trip," Hong Kun pointed out.

Zhou Huan laughed. "A kilometer is a kilometer. We can use the time to observe the surroundings. If there's trouble when we come down, we won't have an easy escape."

"Master always thinks things through thoroughly," the master and disciple headed up the path toward the mountain. Since it was an overcast night, they relied solely on the beam from their cell phone flashlights to illuminate their steps as they climbed.

The mountain path at night was exceptionally difficult to navigate. The only small mercy on Old Bald Mountain was the near absence of large trees, which allowed their phone lights to function with maximum effectiveness, even if the beam didn't reach far ahead. The mountain wasn't excessively high; its defining characteristic was the abundance of scattered stones. Even the winding ascent path was littered with rock fragments, and a single misstep could send pebbles tumbling down with a clattering sound.

"Ouch!" Hong Kun stepped on something round, causing his body to slip, nearly sending him tumbling off the stone cliff. Zhou Huan's strong hand clamped down on Hong Kun’s arm, and with a powerful pull, he hauled his apprentice back up.

"Good thing you aren't too heavy; otherwise, I might have pulled both you and the master down," Zhou Huan said, a reminder mixed with affection for his student.

Hong Kun, shaken by the fright, also felt apologetic; worrying his master about his safety was certainly improper.

Tense but helping each other, the two finally reached the mountaintop. The summit featured a ten-meter-square clearing, though the ground was predominantly stone.

"Master, look at that large rock," Hong Kun shone his flashlight toward a massive, oval-shaped stone over two people tall. It had an extra protrusion at the front, another at the back, and four distinct outcroppings at the corners—it truly resembled a turtle.

Zhou Huan swept his flashlight around the stone before confirming, "It looks like we’ve arrived. This is the Turtle Stone. It’s unsettling, why would that old man choose to bury his grave here?"

The two moved close to the stone and searched for a long time but couldn't find the supposed tomb.

"Master, are you sure that spirit you spoke to didn't just spout nonsense?" Hong Kun showed some doubt regarding the old ghost's words.

Zhou Huan shook his head. "Since he needed our help, he wouldn't speak carelessly. If he said his grave was here, it probably isn't a falsehood. But I suspect his 'grave' might not be a tomb, but rather the location of the remains." With that, Zhou Huan pulled out a stack of talisman papers and a bundle of spirit money from his bag. "Burn these. If there are any lonely spirits around, this will surely draw them out."

Hong Kun followed the old method, lighting the paper money and the talismans together while reciting the soul-summoning incantation.

Zhou Huan swept his flashlight back and forth. It appeared the only place this massive stone could conceal a person or a corpse was in the large fissure at the very bottom. However, this crevice was completely inaccessible, making it impossible to retrieve anything from inside. The only option would be to move the stone above it and then send someone down.

Hong Kun's chant was powerful, and soon, several bizarre spirits appeared on the mountaintop—their bodies a sickly green, completely limp on the ground.

"Hoo-hoo, hahaha!" The spirits suddenly laughed, "After being dead for so long, we finally see the light! This is damn refreshing!"

When Zhou Huan turned to look at the spirits, they were already scrambling forward to snatch the spirit money Hong Kun had burned.
