The reunion between Zhen Huan and the emperor's Ling Yunfeng is a scene carefully planned by Zhen Huan.
Zhen Huan actually understands that the emperor still has feelings for her, and Ling Yunfeng's reunion is the result of her step-by-step layout, and the emperor can't resist this feeling.
Zhen Huan carefully planned a meeting with the emperor.
She took advantage of the emperor's thoughts and guilt for her, as well as his obsession with Chunyuan, to make him leave the palace on the day of the second dragon in February, go to Ganlu Temple, and then meet her on Lingyun Peak.
On Lingyun Peak, the time and place are favorable, and the emperor is deeply in love.
And Zhen Huan's purpose is to give birth to her and Guojun Wang's child.
In order to lay the foundation for her survival in the palace, and also to give her family a blessing.
The most important part of her plan is to give birth to the child in her womb, and at the same time let the emperor have no suspicion.
She wants to protect her family, as well as her children.
In order to achieve such a goal, she made the emperor mistakenly think that she was pregnant with the emperor's child.
The success of this matter is very important to Zhen Huan, because it is related to her status and safety in the harem.
Being pregnant with the emperor's flesh and blood can make Zhen Huan's harem status stable.
It is also possible to fight for opportunities for her family.
Although Zhen Huan knew that the emperor was not a completely ruthless person, she understood that only feelings were not enough, and the royal blood could ensure her safety. Therefore, she did not hesitate to use the emperor to give birth to the child in her womb.
Zhen Huan knows that the emperor is a person who likes the new and hates the old, amorous and selfish.
She can't get the same sincerity as before, she doesn't love him anymore, she just uses his feelings to achieve her goals.
So on Lingyun Peak, when Zhen Huan went to bed, she was so disgusted that she cried, this was her sadness for her helpless fate, and it was also her hatred and disgust for herself.
She hated herself for having to make such a sacrifice in order to survive.
She hated herself for having to make such a betrayal for the sake of her family.
She hated herself for having to make such a compromise for the sake of her children.
Her tears are the blood in her heart, the wound of her soul, and the sorrow of her fate. 
Behind these tears, it is also related to the hairpin that the emperor took out.
The emperor brought Zhen Huan a token of love with him to explain his intentions.
The hairpins are full of nostalgia and represent their past and emotions.
The appearance of the hairpin was also unexpected by Zhen Huan, she didn't expect the emperor to devote himself wholeheartedly to this relationship. The lingering of the past resurfaced under the stimulation of things and people, which made Zhen Huan cry.
At the beginning, Zhen Huan cherished this hairpin very much, but when she decided to leave the palace and cut off contact with the past, she did not leave with it.
The emperor brought it here, which shows that the emperor was prepared as early as when he came, and wanted to meet Zhen Huan and express his longing for many years.
This made Zhen Huan very emotional, she understood that fate could not be changed at will, and her connection with the emperor could not be completely severed after all, which made her feel very sad when she fell in love with Yunli.
Zhen Huan looked at this hairpin and sighed that fate made people, she gave her sincerity back then, but she was regarded as insignificant by the emperor.
Now she is like ashes, but she sees the emperor putting on an affectionate attitude.
Zhen Huan was terrified and held back her grief and wept.
Zhen Huan didn't want to have an affair with the emperor again, and this time the relationship was reluctant.
She needed to endure great pain to complete this dedication.
In addition, when Zhen Huan had intimate contact with the emperor again on Lingyun Peak, she felt nauseous, and this was because she was pregnant.
She is pregnant with the child of King Guojun.
King Guojun's flesh and blood, she vowed to protect it to the end. So hide the truth and not let the emperor find out.
Zhen Huan must hide from the sky and make the emperor think that she is pregnant with her own flesh and blood. Her sacrifice was to protect the safety of the bloodline of the king of the county in her womb.
Fate makes people, Zhen Huan can't completely get rid of the emperor. There is no hairpin, which means that even if they no longer love each other, the bond between the two is still there.
Fate tied Zhen Huan and the emperor tightly together, even if the relationship has passed, she will be forced to continue the relationship. The cruelty of this fate made Zhen Huan's eyes red.
This scene is full of emotional interweaving and dramatic tension, and it also makes us the audience deeply immersed in it.
