Driven by instinct, she moved and undulated at the quick pace of his penetration. Her vagina contracted and twitched to cater to his penis, and her lewd liquid splashed everywhere every time they become one, making the cloth and boulder under her completely soaked.

"How great! Little Sister, your cunt is so tight." Lan Ziyu felt as if his penis was caressed by countless hands each time he embedded himself deeply into her vagina. The pleasure made him lift his head and roared. "So tight! So good! Urgh~! I'm cumming!"

As he reached the peak of happiness, he pressed himself on her and pushed his member to the deepest of her being. His back muscles tightened, and he shot out all the hot semen stocked in his testicles. The fluid filled Zhou Min's uterus quickly. There was so much it overflowed and spilled out from the entrance of her vagina.

He pulled out his manhood with reluctance even if he was not done ejaculating. As soon as he pulled it out, he spurted the white and turbid semen on her breasts. Then, another wave came, and he shot it on her face before she could react.

Once again, Zhou Min cried and begged him to stop, but Lan Ziyu continued to exercise himself on her while exploring all her sensitive places. Her pleading elated him, causing him to put more energy during their bed sport.

When Zhou Min woke up finally, she laid on a bed and her clothes were already changed. For a moment, she was disoriented, not knowing where she was and how long she has fainted. As for the culprit who caused it all, he was nowhere in sight.

She moved a bit, but there was no energy to continue. Not to mention her lower body hurts like hell. She knew she went over her limit.

When she was thinking about that sex machine, the entrance of the tent opened. Lan Ziyu, dressed in his silvery armor, walked in with a stern expression. His eyes swept the bed and noticed that Zhou Min was awake. Happiness flit through his eyes, but a gloomy facade quickly replaced it.

He strode in slowly to her. Then, he looked down, towering over her. "Speak! Why aren't you in the palace? When did you leave and how long have you been here?"

The onslaught of questions spoken in a cold voice rendered her speechless from fear. She lowered her head and remained silent.

"What? A cat got your tongue? If you're not speaking, it means you're guilty…" His cold tone became sterner. However, when he saw her face filling with tears, all the anger vanished and he sat down quickly, full of concerned. Without hesitation, he hugged her against his armor. "What are you crying for? I didn't mean to reprimand you, but it scared me when I thought you came to the war zone alone. What if something happened…"

Lan Ziyu didn't want to think further. If something happened to his sister, what would he do? No matter how much he thought about it, there was only fear, and it suffocated him. The mere idea of a life without her filled him with an unprecedented coldness as if he was trapped in ice.

"Lan Min, promise me you will be careful and keep yourself safe. Don't put yourself in danger and make me worry again!" Lan Ziyu grabbed her shoulders and stared into her eyes. Zhou Min turned away, not daring to promise him because she knew her time was up. Lan Min's death is near.

"You told me you won't leave me, but you broke your promises again. It was hard to find you, but you almost killed me. Imperial Brother, you're a liar, a jerk! Let's break up…. Yeah… break up…"

"Take back those words!" Lan Ziyu flew into a rage. His tone was no longer full of doting. His eyes turned bloodshot and there was madness within as he looked at Zhou Min. If Zhou Min said another wrong word, she might turn into a corpse. The terrible feeling made her whitened from fear.

"You can hit me, curse at me or even kill me, but don't ever say you will break up or leave me. Don't say that… Take back those words…"

Zhou Min hurried and said, "I take them back, but… Big Brother, can you tell me what is the situation outside?" She finally realized how much Lan Ziyu was crazy in love with his precious little sister. She didn't dare to think about what will happen when Lan Min died. Since he didn't want to leave, she had to plan how to make him continue to live when this body dies.

This was part of Lan Min's wishes and changing the mission goal wasn't an option. She had to consider the possibility that Lan Ziyu decided to follow after his little sister when she dies since his love for her has reached the point of madness. She couldn't allow that even if she knew his life would only be crueler with days and nights lost in the pain of losing a cherished person.

When he saw Zhou Min stared back at him with earnest, he pulled her into his embrace again. "I can promise you anything as long as you don't leave me."

"I want you to promise me three things. Even if you have to use a lifetime, you still have to fulfill it. You can't die as long as it isn't done! I won't forgive you if you break your words again and don't even think to be with me after!" Zhou Min grumbled while pouting.

"Three things and it takes a lifetime?!" When he heard her demands, logic told him there was nothing wrong with Zhou Min's words. However, for some reason, there was an uneasiness in his heart. His intuition was warning him that something is amiss and he must not agree to her conditions.

"Big Brother, can't you even agree to that? I… Don't you love me? Or, was everything you said just deception?" Zhou Min panicked when she saw him hesitate. Therefore, she had no choice but to urge him with that kind of crafty tricks.

"I love you!"

"Then why don't you agree? Are you trying to deceive me with sweet words? Go away! I don't want to see you right now-"

"No! I agree. I listen to you, so what do you want?"

Hearing his answer, she threw herself at him with a sweet smile hung on her face. Next, she stretched out a finger. "First, I want you to merge the other two kingdoms into our empire and become the sole ruler of it. This would be my betrothal gift! Second, once the world is united, find the heaven silkworms and the flowers of darkness. I want those things for my bridal gown. Third, since we are blood-related siblings, Heaven won't allow us to have children. So, I want you to find a suitable child to cultivate as the heir of the empire."

Zhou Min was confident Lan Ziyu won't suspect anything. On the contrary, her requests would make him endlessly happy. As she expected, he smiled right after hearing her words. The happiness let him ignore the uneasiness in his heart. He stroked her head while gazing into her lovely but headstrong countenance. "Even if you don't say it, I will still send you the best betrothal gifts! As for your last request, we can ask the branch families to let us adopt an orphan in the clan, so he can become our child."

"It's a promise then!" Zhou Min chirped.

"Yes, it's a promise!"

"Then, you must swear!"

"Why do I have to swear? Don't you believe me?" He was a bit annoyed that she didn't trust him.

"Who told you to have bad records? I can count at least five times when you left me behind or abandon me. This time, you have to swear. If you don't complete the three requests, even in death we won't meet again!"

"Lan Min, do you know what you're saying?" Lan Ziyu became suspicious by her insistence and was also dumbfounded that she would force him to swear.

"Aren't you already in the process of uniting all three countries? Or are you thinking this was an impossible task? Or is our love only amount to that? Easy and cheap?!" Zhou Min once again played the emotion card. She also let Lan Ziyu see her tears and her despair.

"You don't believe my love for you…"

"No! I'm scared of the secular world… I am scared that one day, they will force me to leave you again. Once separated, it will be like the other five times – you are gone and I am left alone!" Zhou Min showed her fear and vulnerability. The sight made Lan Ziyu's heart clenched in pain.

"It's my fault. My estrangement has turned you fearful. Fine. I will swear that from now on, I will use my life to complete your three wishes. If I can't realize them, even in death, we will not see each other again!"
