When he saw the letter, Su Zhiyuan was slightly puzzled, this letter was sent by Master Zen Yin.

She and Master Zen Yin hadn't been in touch for a while, and since Yun Ge was sent back, she had hardly contacted Master Zen Yin again, because everyone was quite busy during this time.

But now Master Zen Yin suddenly sent her a letter, which made Su Zhiyuan a little puzzled, and hurriedly opened the letter to see what was said inside.

However, when she read the contents of the letter, her face changed.

"Miss, what's wrong with you? Why did you look so bad when you saw the things in this letter, did you say something bad? Qiu Xue looked at Su Zhiyuan like this, she was really a little worried, she looked at Su Zhiyuan uneasily and asked.

After thinking about it, Su Zhiyuan shook her head slightly, although she didn't know where Master Zen Yin got this news, but she had always believed in the news sent by Master Zen Yin.

"Maybe someone has long been tired of me and Sikong Mubai, so I want to take this opportunity to teach the two of us a lesson." After thinking about it, Su Zhiyuan said with a slight smile.

Since ancient times, open guns are easy to dodge, hidden arrows are difficult to prevent, there are many difficulties and troubles in this former harem, she has survived with Sikong Mubai, like this carving insect skills, she didn't pay attention to it at all.

She took the letter to Sikong Mubai, and Sikong Mubai thought deeply when she saw the letter.

"Then it seems that someone is going to take advantage of the time of the sacrifice ceremony to do something to the two of us, but speaking of which, if this person really wants to do something to us at that time, he is really a smart person, after all, if you talk about it, anything that happens on the day of the sacrifice ceremony can be interpreted as providence, if the will of heaven wants to kill me, it means that what I have done has been so vicious that the sky can't see it." Sikong Mubai said with a sneer.

"Master Zen Yin only sent me such a letter, as for the rest of the nothing, I don't understand, but I have a strong sense of uneasiness about this matter, so I sent this letter to you, I hope you can understand the situation and make arrangements as soon as possible." As he spoke, Su Zhiyuan took the letter back to him, looked at the handwriting on it, and said in a deep voice.

I have to say that the writing of the master of Zen Yin is really beautiful, even if it is written such an anxious thing, his handwriting is as calm as ever, which makes people look at it and calm a lot.

"Now that I know about this matter, you don't have to worry too much, I'll send someone to check if there is anything suspicious on the altar of the Heaven Sacrifice Ceremony." Sikong Mubai called his own people as he spoke, and asked them to check the matter of the Heaven Sacrifice Ceremony.

Su Zhiyuan sighed, he didn't expect that even if Sikong Mubai came out of the prison, there were so many people who wanted to target him openly and secretly.

"It's really embarrassing for you to go through so many such unbearable things with me." Sikong Mubai looked at Su Zhiyuan with some apologies and said.

Su Zhiyuan sighed, where is this?

"Since I chose your day, I didn't think about backing down, no matter what happened, I would follow you, I believe I have the ability to help you, if I don't have that ability, I won't always be by your side." Su Zhiyuan's face looked at him very firmly and said.

However, just as Sikong Mubai's people were about to go to check the situation of the altar, they were rejected by the guards.

"Those people said that it was about to be time to worship the heavens, and no one should approach here at will, otherwise if something happened, who would bear it?" The person sent came back and looked at Sikong Mubai with some frustration and said.

When he heard this, Sikong Mubai nodded slightly, he was not too surprised that he would be rejected.

However, when Su Zhiyuan heard these words, his heart was full of uneasiness.

"I think there must be something strange in this, even if they are worried that someone will do something in it before the festival, but ...... Forget it, I can't say what's wrong right now, but you have to believe me, there is definitely something wrong with this matter. Su Zhiyuan looked at Sikong Mubai with a little anxiety and said.

Sikong Mubai smiled slightly when he saw Su Zhiyuan so anxious, there was a person who had been worried about him by his side, and the feeling of worrying about him was different.

"Okay, I know, since we can't get in now, then we can only watch everything around carefully on the day of the Heaven Sacrifice Ceremony, so that no one has a chance to hurt us." Sikong Mubai said as he reached out and gently touched Su Zhiyuan's head.

He actually rarely does this action, just because Su Zhiyuan thinks this action is too stupid, very much like coaxing a child.

However, recently, Sikong Mubai found that this action could really calm Su Zhiyuan quickly.

"You also stay in the Su family in the past two days, don't run around, I still have some things to do here, I may not have time to take care of you, don't worry, I'll look for you when I'm done." Sikong Mubai said as he reached out and gently patted the messy letters around him.

Although Li Yuanhang's matter, the emperor had already asked him not to investigate it anymore, but Sikong Mubai's heart was still a little uneasy, and he still decided to secretly check the things behind it.

Su Zhiyuan also knew about this matter in her heart, and she didn't stop Sikong Mubai.

"Okay, in that case, then you can go about your own business, and if you need my help, just talk to me." After Su Zhiyuan said this, in order not to disturb Sikong Mubai, he hurriedly left here.

After watching Su Zhiyuan leave, Sikong Mubai's face, which had been smiling just now, changed.

He hadn't been aware of what Su Zhiyuan said, but if she hadn't brought a letter from Master Zen Yin today, he would have been kept in the dark on the day of the incident.

"You go and send some more people, and on the day of the Heaven Sacrifice Ceremony, you must remember to protect Miss Su's safety, and watch if there are any suspicious people around." Sikong Mubai looked up at the few secret guards standing in front of him and said.

"Your Highness, if there is any suspicious person, shall we take it immediately?" Several of the guards didn't seem to understand what they were going to do right now.

Sikong Mubai thought about it, he didn't have any evidence in his hand now, if he wanted to take down the person directly and make a big fuss, it would be easy to be framed, but if he didn't take it directly, he was afraid that he would let it go.

"When the time comes, I'm afraid I'm going to bother you to keep an eye on it, if there is evidence, I will take them down directly, if not, I have to keep an eye on it a little more." Sikong Mubai said with an unkind face.

The day soon came to the time of the sacrifice ceremony, and Yun Guifei could have come as a concubine, but she took a leave of absence, saying that she was not feeling well and refused.

Su Zhiyuan knew that in the past, Concubine Yun would appear at the Heaven Sacrifice Ceremony, and that was because the emperor wanted her to be by his side.

But now that the emperor has forgotten about Concubine Yun, she is naturally happy and leisurely, and she is unwilling to get involved in these things anymore.

Su Zhiyuan didn't care about these details, since Yun Guifei liked it, then let her go, as long as she was safe.

The emperor and the crown prince came here one after the other, and when they saw the emperor, everyone knelt down and shouted long live.

The queen stood by the emperor's side, and accepted everyone's worship with him, she squinted her eyes, even if she was reprimanded in public a few days ago, it was still her who could stand beside the emperor and accept the worship of ten thousand people, not those show girls.

"This festival is held every year, in order to pray to the heavens, praying that I will have a smooth wind and rain in the past year, and there will be no disasters and no difficulties!" As he spoke, the emperor was already standing on the altar.

After lighting the fire that needs to be lit, you can put all the offerings on it, and after the teacher has finished reciting the prayers, you can throw some of the offerings into the fire.

It was not the first time that Su Zhiyuan had participated in such a ceremony, but today her heart was extremely nervous, not because of anything else, but because of the letter from Master Zen Yin, which made her whole person highly concentrated now.

Although Sikong Mubai was standing behind the emperor, his eyes were still observing in the crowd.

He and the crown prince, as children of the royal family, are also one of the candidates for the succession to the throne, and after the emperor comes down, they will go forward separately to pray.

However, at this moment, he noticed that there seemed to be a person beside him who had been aiming at him, and he was still flustered.

With his many years of experience, Sikong Mubai immediately sensed that there was something wrong with this person.

He hesitated for a moment, and his eyes swept over the people he had arranged in the crowd, and sure enough, those people also noticed this person at the same time after receiving Sikong Mubai's gaze.

After the emperor finished speaking, he was the prince, and after the prince finished speaking, he was Sikong Mubai, and just when he was about to step forward to speak, there was a "boom", but the altar suddenly exploded.

The moment the altar cracked, Sikong Mubai flashed to the side with his instinct.

The crown prince was standing behind the emperor at this time, so he was not affected, but at the moment when the emperor exploded on the altar, he didn't have as good skills as Sikong Mubai, but there were few people in front of him, and he was hit by the stone that broke on the altar.

After the emperor was hit, he took a few steps back and stumbled a few times, but in the end he fell to the ground because his body balance was really bad.

The emperor, who usually chokes on a mouthful of water to make the people around him nervous, was knocked to the ground by such a sudden scene at this moment, and the people around him instantly became nervous, and the next moment he shouted to arrest the assassin, shouted to escort the driver, and passed on the voice of the imperial doctor, one after another.

Su Zhiyuan stood not far away, quietly observing all this, she saw that just when Sikong Mubai was about to take the stage, the suspicious person who had just been noticed suddenly gave a look to the people around her.

Not long after he gave this look, the altar suddenly exploded, and the exploded stones were straight towards Sikong Mubai.

But fortunately, Sikong Mubai's body has always been relatively athletic, so he reluctantly avoided it.

"Your Majesty, how are you? How could such a thing happen suddenly, how could this good thing explode? When Su Zhiyuan stepped forward, he heard someone talking.

yes, how could this altar explode? When Su Zhiyuan heard this, the corners of his mouth hooked up a sneer.

It seems that Master Zen Yin sent a letter, and it was this matter that made her pay careful attention, Su Zhiyuan frowned when she thought of this.

She and Sikong Mubai glanced at each other, and with just one look, they exchanged their thoughts.

Now the two of them don't have much time to worry about anything, Sikong Mubai immediately went to the emperor's side after relieving himself, and he squatted down to check the emperor's current situation.
