With three superpowers at his fingertips, he could dominate the 1970s.

After a period of family reunion, the weather is getting colder and colder.

Su Wenhao took Su Wenbin and his wife to Bei'an County, while his uncle and aunt went to handle business in Gangcheng. Su Jinglun looked at the empty mansion, then glanced at Jiang Zhiyu, and sighed, "They said they'd let us live separately, but look at this, is there even a soul in sight?"

Jiang Zhiyu pointed to herself: "Am I not human?"

Then she pointed at her grandfather: "Aren't you human?"

Su Jinglun is about to make a move again.

Seeing the old man choke on his words, Jiang Zhiyu went over and took his arm: "You can just stay here and relax. My parents will be back tonight. Whatever you want to eat, just ask Aunt Ma to cook it for you. Go out for a stroll, play chess or tai chi with some other old men. Life is so comfortable."

Su Jinglun sighed, "Alright, go do what you need to do. The jeep at the door has been waiting for ages, stop dawdling. Do you think your grandpa needs your comforting words?"

Jiang Zhiyu hugged her grandfather again, then turned to see her grandmother tending to her herbs in the garden, still as carefree as ever. She waved to her grandmother before heading out the door.

Once in the jeep, she asked, "Old Zhuge didn't tell me where I was going?"

"The former director said you should go to the Second Administration Bureau; someone is waiting for you."

Jiang Zhiyu then said no more.

......

Upon arriving at the Second Administration Bureau, Jiang Zhiyu went straight to her office.

Inside sat Zhong Dingwen, Yan Nantian, and Zhuge Yunhe. All three looked rather grim, and a pile of documents lay spread out on the table.

Jiang Zhiyu pushed open the door and entered: "Director Yan, it's been a long time."

He nodded to Zhuge Yunhe and Zhong Dingwen again.

After she sat down, Yan Nantian finally spoke: "You're such a busy person, I always have to ask you three or four times to see me."

He handed over a stack of documents: "This is the latest information we've gathered. The 'little devils' are frequently sending spies to Mount Tai, who knows what wicked scheme they're plotting. Three groups have already gone, and when we arrived, we didn't even see a trace of them."

He paused, his expression grave: "So the reason we've come here is that these people might be individuals with special abilities. It's also related to the anomalies that Senior Xu Yunzi sensed."

Jiang Zhiyu picked up the documents, flipped through them, and clicked her tongue. She glanced at Zhuge Yunhe: "Xu Yunzi is really going against the little guy."

Zhuge Yunhe's lips twitched, but before he could speak, Jiang Zhiyu added, "This ill-fated relationship is something you can't sever."

Yan Nantian then said solemnly, "Senior Xu Yunzi must have sensed what they've done again."

Zhuge Yunhe then spoke, "They're messing with the earth's veins again. My senior brother said there was something strange about the veins, and I sensed it too. I wanted to go with him, but he stopped me."

Then he looked up at Jiang Zhiyu and said, "I'll go with you this time."

Yan Nantian pushed all the remaining documents in his hand over: "These are some other documents about that area. Take a look at them first, and destroy them after you're done. This is a backup."

Zhuge Yunhe put the documents into a file folder, then turned to Zhong Dingwen: "Keep an eye on things at the bureau. If they've sent a lot of people this time, it can't be a single operation."

Yan Nantian clenched his fist: "These people, their desire to destroy our country remains undiminished; they only think of evil schemes and cause sabotage."

He stood up: "Alright, now that the documents have been delivered, I'll be going. Our department has been really busy lately."

He gave Jiang Zhiyu another deep look: "This matter is also related to you."

Jiang Zhiyu asked in surprise, "What does this have to do with me?"

Yan Nantian laughed heartily: "That's a matter of utmost importance. The things you brought back, the technological breakthroughs one by one—even if we try to keep it a secret, some minor details will inevitably leak out. Wouldn't they get anxious then?"

Jiang Zhiyu nodded knowingly: "That's because our country's scientists are amazing. They worked tirelessly, sacrificing countless hours, to achieve this technological breakthrough."

Yan Nantian nodded: "So recently our bureau has been in a complete mess, with all sorts of intelligence coming in non-stop, it's really a tangled mess."

......

Two days later, Jiang Zhiyu and Zhuge Yunhe arrived at the foot of Mount Tai.

Jiang Zhiyu used her mental power to sense it and felt a little uncomfortable.

Seventeen reminded him in his mind: "Host, the magnetic field here has indeed been disrupted; it must be a problem at the mountaintop."

The two climbed upwards. Zhuge Yunhe, being older, was panting heavily halfway up. Jiang Zhiyu, on the other hand, didn't feel anything; upon reaching the summit, she felt refreshed and invigorated.

Zhuge Yunhe had already begun scouting the surrounding area. After walking only a few steps, he called out to Jiang Zhiyu.

"Girl, my senior brother has been here before. Look, there are remnants of an array here."

Jiang Zhiyu leaned closer to take a look and saw several shallow marks on the ground, which were almost invisible unless you looked closely.

"You mean Xu Yunzi set up an array here?"

"Yes, it must have been interrupted by an external force during the formation process." Zhuge Yunhe said, taking two steps forward, squatting down, and pointing to a dark brown mark on the ground. "Look, there's a faint bloodstain on the ground."

Jiang Zhiyu's heart tightened. Something had happened to Xu Yunzi.

Seventeen then reminded him, "Host, head southeast."

Without a word, Jiang Zhiyu grabbed Zhuge Yunhe's sleeve and headed southeast. After walking about a hundred meters, they saw freshly dug pits on the ground. The soil was new, and its color was distinctly different from the surrounding withered yellow leaves.

Jiang Zhiyu looked at the shape of the pit and her heart skipped a beat. Had Xu Yunzi been buried?

Seventeen immediately interrupted her wild thoughts: "Host, this isn't a place to bury people. There's a nauseating smell down there."

Jiang Zhiyu's heart sank. She took out a shovel from her spatial storage, handed one to Zhuge Yunhe, and the two began to dig.

When they had dug about 70 or 80 centimeters deep, the shovel hit something hard. Zhuge Yunhe immediately pulled Jiang Zhiyu aside: "Don't move, I'll handle it."

Jiang Zhiyu clearly saw that it was a black iron nail, about the length of a forearm, with a dark, eerie glow. The nail was densely covered with tiny runes, as fine as mosquito legs, which were even slightly wriggling, as if they were alive. The soil around the nail had an abnormally charred black color and emitted a pungent, fishy stench.

Zhuge Yunhe's expression changed drastically.

He crouched down, his hand hovering about an inch above the nail, feeling the chilling aura emanating from it, his fingers trembling slightly.

"The pulse-suppressing nails." His voice was extremely low. "The exact same pulse-suppressing nails as the ones my senior brother removed 46 years ago."

Although Jiang Zhiyu had never seen the actual object, he had heard Xu Yunzi describe it in detail. Cast from a special alloy, it was soaked in the essence and resentment of the caster. After being driven into the dragon vein's acupoint, the earth's energy leaked out little by little, as if a hole had been punched in it.

She frowned. "Are they using this trick again?"

Zhuge Yunhe didn't answer, his gaze fixed on the nail. After a long while, he finally spoke, his voice hoarse: "That's not all. Look at the runes on this nail; they're more complex than what my senior brother described back then, and the resentment is much stronger."

Seventeen quickly added, "Host, about twenty meters below this nail lies the main underground water vein of Mount Tai. It's been driven in for some time, and the earth's energy is slowly seeping out. If it's not removed, over time, the mountain springs in this area will turn yellow and dry up, the rock strata will become loose, and the risk of landslides will increase."

Jiang Zhiyu took a deep breath, reached out and covered the Zhenmai Nail, tightened her mental energy, and directly put the entire nail and the surrounding contaminated soil into her space.

The ground suddenly collapsed, creating a sizable pit and revealing the dark gray rock layer underneath.

"If they're planning to cause trouble, there must be more than one spot," Jiang Zhiyu said, patting the dirt off her hands. "Let's find them quickly."

......

Following the clues from the first location and the faint traces on the ground, the two quickly found the second burial site.

Using the same method, the shovel dug through the soil, and another Pulse-Suppressing Nail lay there quietly. The runes writhed faster than the first one, and the resentment it emitted was even stronger.

Zhuge Yunhe, watching from the side, turned ashen-faced: "Two already. They're trying to completely destroy the fortune of Mount Tai, the foremost of the Five Sacred Mountains."

Jiang Zhiyu also stored the second Suppressing Pulse Nail into her spatial storage. The moment she put it in, she clearly felt the ground beneath her feet tremble slightly.

The two continued their search along the trail, eventually finding themselves deep at the base of a mountain. There, they found a natural horizontal stone beam, serving as the load-bearing structure of the mountain.

Jiang Zhiyu squatted down for a closer look and gasped in shock.

Three pulse-suppressing nails were prominently nailed to the stone beam, arranged in a triangular pattern. Each nail was thicker than the ones previously discovered, and the runes on the nail heads did not wriggle but instead moved directly across the iron surface, like three black snakes slowly crawling.

Seventeen also urgently reminded, "Host, the thermal expansion and contraction of these three nails, along with the seasonal temperature changes, will continuously widen the cracks in the rock. Over the years, this will tear apart the mountain structure. The key is that the damage is not yet visible to the naked eye, but the internal rock layers will continue to crack. Moreover, they are nailed to the load-bearing stone beams; once the beams break, half the mountain will collapse."

Without hesitation, Jiang Zhiyu reached out and covered it, her mental energy tightening sharply. The three pulse-suppressing nails were simultaneously pulled out and stored in her spatial storage. Three finger-thick holes were left in the stone beam, the rocks at the edges of the holes already blackened, and a faint, foul odor seeped out.

"These holes can't be left standing," Jiang Zhiyu said, turning to Zhuge Yunhe. "Have the comrades from the Taishan Management Office come and seal these cracks completely with grout; we can't let them pose any further risks."

Zhuge Yunhe nodded, his face as black as the bottom of a pot. He squatted down beside the stone beam, touching the blackened holes with his hand. A layer of dark gray powder clung to his fingertips; he rubbed it, and his voice lowered further: "The rock has been eroded. They've been driving them in for at least two or three months."

Jiang Zhiyu stored the eroded rubble into his spatial storage, then looked back in the direction he had come from: "Senior Xu Yunzi's formation was interrupted, and he bled. This means he had already discovered these things and was preparing to counterattack, but his plan was thwarted by the enemy."

Zhuge Yunhe stood up, his gaze following the faint footprints on the ground: "Let's go, follow the tracks. Since my senior brother made his move, he must have left other clues."

......

The two continued their search along the roadside tracks, straying further and further off course, leaving the stone steps of the scenic area behind, their feet on withered grass and pebbles. There were indeed footprints on the ground, and the grass they had trampled hadn't fully recovered.

Following the footprints, we arrived at a natural cave. The entrance was partially hidden by bushes, making it almost invisible without careful observation.

Jiang Zhiyu used her mental power to probe into the cave and immediately pulled Zhuge Yunhe to stop outside the cave.

There were people inside, and quite a few of them.

She lowered her voice and said to Zhuge Yunhe, "Wait a moment, let me put some poison in first, then go in and see who it is."
