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

The cracks in time and space twisted and flickered like a broken mirror, and the figure of the old national teacher gradually solidified. He stroked his beard, his expression as serious as if he had just swallowed a fly.

"Teng Junze, Fan Mengmeng, are you okay? I..." Before he could finish his words, he was stunned by the mess in the laboratory.

"This... who the hell did this? Did bandits rob the national treasury?"

Teng Junze coughed lightly and signaled Fan Mengmeng to explain with his eyes.

Fan Mengmeng shrugged helplessly and simply recounted what had just happened, omitting the thrilling part where Aqiang almost blew up the space-time rift.

After hearing this, the old imperial teacher's expression changed from shock to contemplation, and finally settled on a meaningful expression.

"Although the process... uh... was a bit tortuous, the result is good." He paused, his eyes landing on Teng Junze. "However, before repairing the space-time rift, I have one final test for Junze."

Teng Junze raised an eyebrow, a sense of foreboding washing over him. "What test?"

The old state teacher smiled mysteriously and waved his sleeves. A complicated formation diagram appeared on the wall of the laboratory. The lines were intertwined and the symbols were obscure and difficult to understand, which was dazzling to look at.

"This is an ancient magical formation called the 'Qian Kun Lock'. If Jun Ze can break it within one day, I will fully trust your plan."

Fan Mengmeng gasped. This formation was a hundred times more complicated than any circuit diagram she had ever seen!

She looked at Teng Junze worriedly, but he just smiled faintly.

"National Master, are you... serious?"

The old imperial teacher stroked his beard, a hint of cunning in his smile, "Of course."

Teng Junze took a deep breath, walked to the formation diagram, and looked at it with a sharp gaze.

Fan Mengmeng's heart was in her throat. This was a crucial battle that would determine whether they could return to their respective time and space!

"This...this thing, why does it feel even harder than the Nine Linked Rings?" Teng Junze muttered to himself, extending his finger and lightly touching a symbol on the formation diagram...

Teng Junze was not frightened by the childish name "Qian Kun Lock", nor was he confused by the tangled lines.

He narrowed his eyes and carefully observed the formation diagram as if scanning a QR code.

This thing may seem confusing at first glance, but if you look closely, hmm... it seems a little familiar?

"Wait, why does the structure of this thing look a bit like the 'magic square' recorded in the 'Nine Chapters on the Mathematical Art'?" Teng Junze touched his chin, feeling that he had grasped something.

In order to please the old imperial teacher, he had read through all the ancient books in the imperial teacher's collection. He didn't expect that they would come in handy now!

"666, you are worthy of being the man I like!" Fan Mengmeng looked at him with stars in her eyes and gave him some flattery at the right time, which made Teng Junze very motivated.

He took a deep breath and began to try to crack it.

His fingers moved across the battle formation, as if commanding thousands of troops, sometimes tapping lightly, sometimes swiping across, leaving a trail of afterimages.

Fan Mengmeng was dazzled and felt like she was watching a high-tech magic show.

As time passed, the symbols on the formation diagram began to flicker and emit a faint light.

Just when he was about to succeed, Teng Junze suddenly stopped and frowned.

"What's wrong?" Fan Mengmeng's heart suddenly rose to her throat.

"It's a bit tricky," Teng Junze pointed to a node in the center of the formation diagram, "This place can't be solved using conventional methods."

The atmosphere froze instantly, as if you could hear a pin drop.

Fan Mengmeng felt like her breathing had stopped. Was she going to fail?

At this moment, Teng Junze's mouth suddenly curled up into an evil smile.

"If conventional means don't work, then let's go against the norm!" A cunning flashed in his eyes, and he stretched out his hand and poked that node hard...!

"Hey? Wait! What are you doing--" Fan Mengmeng exclaimed.

Before Fan Mengmeng could finish shouting "What are you doing--", she saw the "Qiankun Lock" emitting a dazzling light, and then a light gate appeared out of thin air!

"Oh my god! It really works!" Fan Mengmeng was stunned. This operation was too wild!

This is not a method of breaking the formation, it is clearly a violent demolition!

She couldn't help but give Teng Junze a thumbs up: "Boss, you are really awesome!"

Teng Junze raised his eyebrows, with an expression that said "don't do this!"

He casually brushed off his sleeves, turned to look at the old imperial teacher, and waited for his evaluation.

The old imperial teacher stroked his beard, a hint of surprise flashing in his eyes.

He originally thought that Teng Junze would follow the traditional solution step by step, but he didn't expect that this kid would take a different approach and use such an incredible method to open the Qiankun Lock.

However, the results are good.

He coughed lightly and was about to speak, but saw Teng Junze suddenly cover his chest with his hands, his face pale.

"What's wrong?" Fan Mengmeng quickly stepped forward to support him, "Did you consume too much energy?"

Teng Junze shook his head, pointed at the light door, and said weakly: "It seems... I opened the wrong one..."

"Huh?" Fan Mengmeng was confused. "What do you mean by opening the wrong door?"

The old national teacher's face darkened, and he quickly walked to the light door and stretched out his hand to explore.

He withdrew his hand and uttered two words with a serious expression: "Demon Realm..."

Fan Mengmeng: ???

Teng Junze leaned weakly against Fan Mengmeng and said weakly, "Mengmeng, I...I seem to have gotten into trouble..."

The old imperial teacher's face was darker than the bottom of a pot, and his beard was twitching with anger.

"The Demon Realm? You opened the door to the Demon Realm? Why don't you go to heaven?!" The old national teacher puffed his beard and glared, almost suffocating.

Fan Mengmeng quickly took out the quick-acting heart pills she had brought from the modern era and handed them to the old Imperial Master: "Old man, calm down, calm down! Here, have some chocolate to calm your nerves!"

The old imperial teacher looked disgusted and said, "What the hell is this? I don't eat these weird things!"

Fan Mengmeng thought to herself: This is chocolate imported from Belgium, what a waste!

Teng Junze coughed twice at the right time and said weakly, "Master Imperial Master, actually... I did this on purpose."

"Did you do it on purpose?" The old national teacher and Fan Mengmeng said in unison, both looking at him as if he were a fool.

Teng Junze forced himself to sit up straight and explained, "To break this Qiankun Lock, one must inject powerful spiritual energy into it to unleash its true power. And this door to the demonic world is the key to unlocking the true treasure house."

"You're being mysterious again!" The old Imperial Master was skeptical. "How come I've never heard of such a statement?"

Teng Junze smiled mysteriously, "That's because only the Chosen One can know the solution." He paused and looked at Fan Mengmeng affectionately, "And Mengmeng is that Chosen One."

Fan Mengmeng was confused: "Ah? What does this have to do with me?"

Teng Junze pointed at the light gate leading to the demon world and said, "Only Mengmeng's blood can open the true treasure house."

"Huh?" Fan Mengmeng's eyes widened. "You don't want me to die, do you?"

Teng Junze smiled gently: "Of course not, I just need a drop of your blood." As he said, he took out an exquisite knife.

"Wait!" The old national teacher suddenly said, "Why does this routine feel a little familiar to me?"

Teng Junze: “…”

Fan Mengmeng: “…”

"Ahem," Teng Junze cleared his throat. "Master Imperial Master, you worry too much. Without further delay, let's open the treasure house quickly." As he spoke, he handed the knife to Fan Mengmeng.

Fan Mengmeng looked at the gleaming knife and swallowed her saliva: "Well...how about you do it?"

"Mengmeng, believe me." Teng Junze held her hand gently.

"not me……"

"Mengmeng..."

Fan Mengmeng looked at Teng Junze's deep eyes and finally compromised.

She gritted her teeth and stretched out her finger...

"Wait!" A shrill voice suddenly sounded.

Everyone looked in the direction of the sound and saw a man in gorgeous clothes walking towards them.

He looked at Teng Junze and Fan Mengmeng with a sinister look on his face, and a sneer appeared on the corner of his mouth: "Want to open the treasure house? It's not that easy!"
