Mu Hanyan came to Yue Fanchen and found that he was leaning over a stone desk, staring at a letter intently.

"Beichen, Rui'an, when you read this letter, I may no longer be here..."

When Mu Hanyan saw the first few sentences, her head buzzed and her mind went blank for a moment!

This letter was written to my grandfather and father. Could it be that the owner of this cave is my grandmother?

Mu Hanyan calmed herself down and then looked down.

"Beichen, Rui'an, when you read this letter, I may no longer be here.

Originally, I should have returned to Anyun to reunite with you, but just as I was about to leave Beiyuan Wuyuan, I discovered that Hanyan's identity might be much more complicated than we imagined, and the enemies she had to face were also much more powerful than we imagined.

Fortunately, that person was confined by the laws, trapped in the North Abyss Mist Plain. Perhaps, not even the Holy Court knew of his existence. But one day, he would break free from the shackles of the North Abyss Mist Plain. That would be a disaster not only for the entire Holy Court continent, but also for Han Yan herself.

For Han Yan, I must stay and find an opportunity to get rid of this person.

But he is too strong, and I don’t know if I can leave Kitaenchi Kirihara alive. If I can’t go back after all, remember to take good care of yourself and don’t feel sad for me.

My strength improved too late, and I had no choice but to send Han Yan to Blackrock City. As her grandmother, I truly owe her too much. This time, I will use my abilities to protect her, even if it means sacrificing my own life. I will never let her suffer even a single ounce of harm. This, too, can be considered our way of making amends for her.

I left some pills for Han Yan. If you can see this letter, use the Mu family's seal-breaking technique to open the seal, take out the pills and give them to her.

Also, don’t tell Han Yan about this. I don’t want her to feel guilty at all…”

The letter suddenly stopped here, leaving only a few conspicuous drops of ink on the letter paper. Obviously, some emergency had occurred and he had to interrupt it.

Although the letter was not finished yet, Mu Hanyan could still guess the content behind it. Obviously, her grandmother did not want her to feel guilty about it and did not want her to have any psychological burden.

Holding the letter, Mu Hanyan's hands trembled slightly and tears rolled down her face.

Beside them, Zhuang Ping'an and others were silent, but they were extremely shocked in their hearts.

It turns out that the owner of this cave is Mu Hanyan's grandmother. The reason why she stayed in Beiyuan Wuyuan was to protect her and eliminate powerful enemies for her!

"Hanyan, I believe that with our grandmother's strength, nothing unexpected will happen." Ye Lanxuan said comfortingly.

"Yeah." Mu Hanyan nodded. Even though she knew that his words were just comforting, she still felt much more at ease.

Who exactly was this enemy that Grandma was talking about? Why was he restricted by the laws and trapped in the Beiyuan Mist Plain? Calming down a bit, Mu Hanyan began to ponder carefully.

Could it be that they were the ones who forced the Qilin Clan to flee their homeland? Mu Hanyan couldn't think of any other possibility. Only they could make Grandmother so fearful.

Thinking of this, Mu Hanyan's heart trembled slightly.

"Young Master Mu, your grandmother has a high level of cultivation. Besides, she also said in the letter that the other party is restricted by the laws, and her strength should be greatly reduced. I think she will be fine." Mu Hanyan did not avoid others when reading the letter. Zhuang Pingan also stretched his neck to see it. Although he didn't know the origin of the powerful enemy mentioned in the letter, he still comforted him.

Yes, since the opponent was suppressed by the laws and trapped in the Beiyuan Mist Source and unable to escape, his strength should have been greatly affected. Grandmother is definitely not a reckless person. Since she has the courage to fight him, she should be somewhat confident. Mu Hanyan finally felt a little relieved.

As for why she stopped writing before finishing the letter, Mu Hanyan guessed the reason. It was likely that Grandmother had sensed the man's aura and hurried over. Beiyuan Wuyuan was tens of thousands of miles in radius. It would take Grandmother a considerable amount of time to track him down and find an opportunity to strike. Perhaps Grandmother hadn't even fought him yet.

"There is a restriction here. There must be some good stuff hidden here. Brother Zhuang, come and take a look." A young man shouted excitedly.

After all, the study is so small, and although everyone gathered here, most people stayed outside the door.

Zhuang Pingan turned his head and glared at the man. He hadn't known who the owner of this cave was before, and he had entertained some thoughts of treasure hunting. But now that he knew the man was Mu Hanyan's grandmother, he naturally didn't dare to entertain any more evil ideas.

"It's okay, let's go and take a look." Mu Hanyan did not blame the man for such a small matter. She smiled, put away the letter and walked over.

A vase was removed from the stone shelf against the wall, and the unique light of the seal flashed on the wall.

"Young Master Mu, this seal looks mysterious and there must be something good hidden inside!" Several young men were standing in front of the stone shelf and said to Mu Hanyan excitedly.

"Shut up." Zhuang Ping'an shouted and winked at them.

Several people were startled and immediately shut up, looking at Zhuang Ping'an in confusion.

Zhuang Ping'an glanced at Mu Hanyan and seeing that she was not angry, he whispered to them the origin of this cave.

After hearing his words, several people were shocked and regretful. They were shocked that the owner of this cave was Mu Hanyan's grandmother, and her strength was so powerful. Unfortunately, no matter what treasures were hidden in the seal, it had nothing to do with them.

Mu Hanyan ignored them and slowly made hand gestures.

Ancient families with a long history like the Mu family all have their own secret sealing methods. Although outsiders can also break them, it takes a lot of effort, while it is much easier for family members to break them. During the time at the Mu family, Mu Hanyan certainly learned such methods.

Not long after, he saw a flash of light before his eyes, and a jade box about one foot long appeared out of thin air. When he opened it, he found that it was full of pills, roughly counting hundreds of them.

Qingxin Zhenyuan Pill, Taiyi Jianyuan Pill, Dragon Blood Resurrection Pill, Nine Transformations Holy Energy Pill... Looking at those priceless top-grade pills, the people around were drooling.

However, no one recognized the pill in the middle. Compared to the other pills, this one was clearly different. It was crystal clear, like a jade carving, and its light was as clear as a flowing spring, giving people a sense of clarity and ethereality.

"What kind of pill is this?" Mu Hanyan looked at the pill in confusion.

To be honest, she is now a master in alchemy. When she was in Longyan College, she read a lot of fragments of ancient books on the experiences of her predecessors, but she knew nothing about this pill.

"I seem to have heard of this elixir somewhere." Ye Lanxuan looked thoughtful, but couldn't remember where for a moment.
