Upon hearing this, Mo Tianfeng hesitated for a moment. He knew that if he told Xu Yuehuai how to break the seal, she might leave the ancient tomb and never return. However, if he didn't tell her, he worried that Xu Yuehuai would kill him.

In the end, after weighing the pros and cons, Mo Tianfeng reluctantly chose to compromise. He took a deep breath of the cold air and slowly said, "The seal on that cave entrance is no ordinary object; it requires a special key to open. And the location of this key is known only to me."

Upon hearing this, Xu Yuehuai's heart stirred. She scrutinized Mo Tianfeng, a sly glint in her eyes. She said calmly, "Alright, since you say so, I'll trust you this once. You'll come with me to find this key, but you must promise not to make any underhanded moves."

Mo Tianfeng nodded, a complex emotion flashing in his eyes. He knew he had no other choice but to rely on Xu Yuehuai's strength to find a way out.

The two walked together deeper into the ancient tomb. The places they passed through were eerie and terrifying, filled with unknown dangers. Xu Yuehuai held a long sword and vigilantly observed her surroundings, fearing that some traps or mechanisms might suddenly be activated.

Mo Tianfeng followed silently behind Xu Yuehuai, his face expressionless, but his eyes revealed an indescribable worry.

Suddenly, a faint sound caught Xu Yuehuai's attention. She immediately stopped and listened intently. Not far ahead, a stone door slowly opened, revealing a dark, secret chamber.

Mo Tianfeng pointed to the secret room and said in a low voice, "The key is inside. Go in and get it yourself."

Xu Yuehuai frowned, looking at Mo Tianfeng warily, and said, "Aren't you going in?"

Mo Tianfeng shook his head, a strange smile playing on his lips, and said, "I can't go in, that's the rule."

Although Xu Yuehuai was puzzled, she didn't dwell on it. She took a deep breath and mustered her courage to enter the secret room. The room was pitch black, with only a faint candlelight barely illuminating the surroundings.

She walked cautiously, afraid of triggering some mechanism. Suddenly, she felt her footing give way, and she plummeted downwards. Xu Yuehuai was startled and immediately drew her longsword, preparing to deal with any potential danger.

However, when she landed, she found herself unharmed. Looking up, she saw that she was standing in a vast underground palace. Strange statues and murals surrounded the palace, giving it a mysterious and eerie feel.

Xu Yuehuai looked around, trying to find the so-called key. However, she didn't find anything suspicious. She couldn't help but wonder if Mo Tianfeng was lying to her.

Just as she was about to leave, she suddenly noticed something strange. The eyes of the statues seemed to be staring at her, and they turned as she moved.

Xu Yuehuai's heart stirred. She slowly walked to a statue and observed it carefully. Suddenly, she noticed something seemingly hidden in the statue's eyes. She reached out and gently pressed the statue's eyes.

With a "click," a small compartment in the statue's eye popped open. Xu Yuehuai was delighted. She carefully reached out and took a small key from the compartment.

She carefully returned to Mo Tianfeng's side, holding the key. Mo Tianfeng's eyes flashed with surprise and resentment when he saw the key in her hand. He hadn't expected Xu Yuehuai to actually find it.

"Alright, now you can tell me how to break the seal, right?" Xu Yuehuai said calmly.

Mo Tianfeng took a deep breath to calm himself down, and then slowly said, "The seal on that cave entrance is a complex magic array. The runes on the array need to be activated in a specific order. I will tell you the order, and you can break it yourself."

Upon hearing this, Xu Yuehuai felt a mix of nervousness and anticipation. She nodded, indicating that she understood. Then, Mo Tianfeng explained the sequence for breaking the seal to Xu Yuehuai.

Xu Yuehuai's heart felt heavy, as if a huge boulder was pressing down on it. She gripped the key tightly in her hand, its cold touch traveling through her palm to her heart, calming her down slightly. Remembering the order of activation Mo Tianfeng had instructed, she took a deep breath and walked towards the dark cave entrance.

She proceeded with extreme caution, each touch of the runes on the magic circle causing her to feel an invisible force surging within her. She could clearly sense that force emanating from the magic circle, like an invisible hand trying to drag her into an endless abyss.

With a "click," the last rune was activated, and the entire magic array suddenly burst forth with dazzling light, as if day had arrived. Xu Yuehuai subconsciously closed her eyes, and when the light subsided slightly, she slowly opened them, only to see that the entire ancient tomb was shrouded in a faint halo.

However, the light did not bring her the joy she had expected. Instead, the entire tomb began to shake violently, as if something terrifying was about to awaken.

Xu Yuehuai looked at Mo Tianfeng in horror, only to see a crazed smile on his face and a bloodthirsty glint in his eyes.

"Hahahaha!" Mo Tianfeng laughed loudly, his voice echoing in the ancient tomb. "You triggered a hellish trap, we're all going to die! None of you will survive! Although I can't leave here either, you'll all be buried with me!"

Xu Yuehuai's heart sank to the bottom. She glared angrily at Mo Tianfeng and demanded, "Are you crazy? Why would you do this?"

Mo Tianfeng's laughter grew even more maniacal. He shook his head and said, "Mad? I'm not crazy! I just want everyone to die with me! This world is too unfair, why should I bear this pain alone?"

Xu Yuehuai gripped her longsword tightly, a resolute glint in her eyes. She knew she had to find a way to stop this madman.

"Mo Tianfeng, what you're doing will only cause more innocent people to suffer. Wake up!" Xu Yuehuai shouted.

However, Mo Tianfeng seemed not to hear her words and continued laughing. He pointed at the shaking ancient tomb and said, "Look at this ancient tomb! It's about to collapse! We're all going to die here!"

Xu Yuehuai's heart tightened. She thought of her lost companions—Qi Guze, Qi Ziang, Tie Chunsheng, and the secret guards. How were they now? Were they also caught in this crisis?

She couldn't let Mo Tianfeng continue like this. Xu Yuehuai took a deep breath, swung her long sword, and charged towards Mo Tianfeng.

"You wanted to die but harmed innocent people. Take this!" Xu Yuehua shouted, her long sword slashing towards Mo Tianfeng with a sharp whistling sound.

A hint of surprise flashed in Mo Tianfeng's eyes; he hadn't expected Xu Yuehuai to attack him so decisively. He dodged Xu Yuehuai's attack with a swift movement.

"Hmph, you think you can defeat me like this?" Mo Tianfeng sneered. "I am the master of this ancient tomb! Everything here is under my control!"
