End of the World Crisis, My Husband is from Ancient Times

"Here..." Fan Mengmeng repeated, her fingertips lightly touching the vermilion door, feeling the mottled texture on it. A chill spread through her fingertips and spread throughout her body. "I think... the entrance is here."

Teng Junze looked around. The courtyard was ordinary. Aside from a few withered trees and a dry well, there was nothing special about it. "Mengmeng, are you sure? There doesn't seem to be anything unusual here."

Fan Mengmeng didn't answer directly. Instead, she walked to the center of the courtyard, closed her eyes, took a deep breath, and felt the subtle energy fluctuations in the air around her. After a moment, she opened her eyes and pointed at the dry well. "If I'm not mistaken, the entrance is at the bottom of the well."

Teng Junze was slightly surprised. "The bottom of the well? But the well is dry, and..." He walked to the side of the well and looked down. There was nothing at the bottom except mud and some gravel. "It looks very ordinary."

"Ordinary spatial layouts often hold hidden mysteries," Fan Mengmeng explained. "Ancient people loved to conceal important places with sleight of hand. This well may seem ordinary, but its location, right in the center of the courtyard, aligns with the ancient feng shui principle of 'hiding wind and gathering energy.' Furthermore," she pointed to some subtle marks around the wellhead, "look at these marks. They look like the remnants of some kind of mechanism."

Teng Junze observed carefully and indeed found some subtle incisions. If Fan Mengmeng hadn't pointed them out, he wouldn't have noticed these details at all. "You're right, I was negligent." A hint of admiration flashed in his eyes. This seemingly fragile woman always brought him unexpected surprises.

Fan Mengmeng pulled a small detector from her bag. It was something she'd brought back from the modern era, capable of detecting certain unique energy fluctuations. The needle on the detector began to swing violently, pointing toward the bottom of the well. "The entrance is right down there," she said firmly.

The two approached the wellhead cautiously. A powerful energy wave emanated from the bottom of the well. Fan Mengmeng felt a palpitation in her heart, and an inexplicable sense of danger enveloped her. "Junze, be careful..." Before she could finish her words...

A powerful gust of air suddenly erupted from the wellhead, sending Fan Mengmeng stumbling backward. Teng Junze quickly caught her. "Mengmeng, are you okay?" he asked with concern, a hint of self-blame in his tone.

Fan Mengmeng shook her head, her face pale. "I'm fine, it's just..." She looked up at the wellhead, where a transparent energy barrier had appeared, shimmering with a pale blue light, like an invisible wall. "It seems like something is blocking the entrance."

She tentatively reached out her hand. As her fingertips touched the barrier, she felt a sharp pain, like a static shock. She quickly withdrew her hand, her fingertips slightly red. "This barrier..." she murmured, her brow furrowed.

Teng Junze also reached out and tried, but was similarly repelled by an invisible force. "It seems ordinary methods won't break through," he mused, a hint of worry in his eyes. Although he had complete confidence in Fan Mengmeng's abilities, facing this unknown barrier, he couldn't help but feel a little uneasy.

Fan Mengmeng bit her lower lip, trying to recall the knowledge of energy and magnetic fields in modern physics. Energy barrier... magnetic field... there must be a way to break it! She closed her eyes, her mind racing, various formulas and theories intertwined and collided in her mind.

Teng Junze stood quietly by, waiting patiently. He knew Fan Mengmeng needed time to think. He didn't have the modern knowledge that Fan Mengmeng had, so at this moment he could only choose to trust her and give her his utmost support.

Time ticked by, the air around them frozen in silence. Suddenly, Fan Mengmeng's eyes snapped open, a glint of light in them. "I've got it!" she said firmly, a hint of excitement. "Magnet! We need to find a magnet!" She glanced around, searching eagerly.

"Magnet?" Teng Junze was a little confused, not understanding why she suddenly mentioned this. "Are there magnets here?"

Fan Mengmeng didn't answer. Instead, she walked straight to a pile of rocks in the corner of the courtyard and began to carefully search. "It must be there..." she whispered to herself as she searched. Teng Junze watched her busy figure, puzzled, but still stepped forward to help.

Finally, under an inconspicuous rock, Fan Mengmeng found a black stone with a faint metallic sheen. "That's it!" She picked up the stone, her eyes gleaming with hope. She handed it to Teng Junze, "Try it."

Teng Junze took the stone and felt a chill in his hand. He looked at Fan Mengmeng in confusion. "What is this?"

"Magnet," Fan Mengmeng explained, "was also called Cishi in ancient times. Try getting close to that barrier."

Teng Junze did as he was told, bringing the magnet closer to the barrier. A magical scene occurred: the pale blue light began to fluctuate slightly, as if being pulled by some force. Fan Mengmeng's eyes lit up, and she quickly searched the surrounding area for similar stones.

"Mengmeng, what are you looking for?" Teng Junze asked in confusion as he looked at her busy figure.

"I need to find a stone that repels this magnet," Fan Mengmeng explained. "If I can find it, I can weaken the barrier."

Although Teng Junze didn't understand the reasoning behind this, he still chose to trust her and searched among the rocks with her. Time passed, and the air around them seemed to freeze in a state of tension and anticipation. Suddenly, Fan Mengmeng let out a cry of surprise. "Found it!"

In her hand, she held a rough, off-white stone, faintly emitting a strange energy. She brought the stone close to the black magnet, and an invisible repulsive force suddenly emerged between the two stones, causing them to tremble slightly.

"That's it!" Fan Mengmeng excitedly placed the two stones on either side of the barrier. A miracle occurred: the blue light on the barrier gradually weakened, and the previously indestructible barrier began to become transparent, allowing a faint glimpse of the scene behind it. Teng Junze was once again impressed by her wisdom, his eyes filled with admiration.

As the energy barrier weakened, the entrance gradually became visible, but strange runes began to flicker around it, emitting a faint red light, like a warning signal. Teng Junze reached out to touch it, but was stopped by Fan Mengmeng.

"Wait," Fan Mengmeng said solemnly, "these runes..." She carefully observed the shape and arrangement of the runes, and a sense of uneasiness rose in her heart.

The entrance was right before her eyes, yet it was filled with unknown dangers. Fan Mengmeng took a deep breath, her eyes determined. "Let's go in." She reached out to push the entrance, only to find...
