Love watched helplessly as her husband Sima Chao married the princess to fulfill his ambition, and she couldn’t help but feel heartbroken.

Sima Chao hugged her into his arms and coaxed softly: “Afu, you are the only one in my heart. If you can stay in the country, I will definitely set you right.”

Love believed him because she was obsessed with him.

It wasn’t until Sima Chao was worried about his princess wife who was about to enter the house that he killed her flesh and blood with his own hands. Only then did Love realize how much sincerity a person who was cruel to his own children could have towards her.

It’s just that he is lying and she is obsessed with it.

Love finally saw clearly the person next to her. She was completely heartbroken and died in despair the day before Sima Chao married the princess in glory.

Starting over, Love decided not to make the same mistakes again, but when she opened her eyes, she saw the whole house was filled with joy, and she actually returned to her wedding night with Sima Chao.

Sima Chao, a great hero of a generation, fought against the princes and unified the world, which was his lifelong ambition. For this reason, he did not hesitate to let down his beloved.

He thought: If she could live in the world, he would give her the highest status in the world, and it would not be too late to slowly repay the deep love he owed her.

As everyone knows, if you miss it, it will be difficult to get it back. When he turned back to her, she had already turned away.

He won the world and had everything, but he only lost her.

When Sima Chao saw her smiling broadly at the man beside her, he finally became anxious, his eyes turned red, and he regretted it.
