The Black Beast’s Useless Concubine - Chapter 2525

Outside the planet, there is a dead and boundless darkness.

Unknown planets are connected, woven into shelters of life, and countless cosmic races explore, develop, multiply, and fight against the empty darkness.

The little nameless clan can gain power for hundreds of years, and the powerful clan of billions of years can disappear in an instant.

Cultivation and inheritance, Tianjiao contends for glory, and heroes rise.

The human race started strong and went to the end.

No. 5 Broken Star, 732 Island Town, Wang Yu started his cultivation.

A few years later, the human race has bloomed in every corner of the world.

Countless human race arrogance looked up at the only human race god emperor.

“God Emperor Wang Yu, how can I cultivate to follow in your footsteps?”

The god emperor looked back and was slightly surprised. “Cultivation is not just repetition over and over again. It will become natural after you have fully practiced. All of you are more talented and savvy than me. I believe I don’t need to say more about it.”

The arrogance of the human race looked at the figure of the god emperor floating away, and remained silent.

“Proficient, what is that…”

What?! The sticking to her daily, eating her tofu (taking advantage of her ) is a cross-dresser?

Not to mention that he is the Evil Highness!! She had slept beside him, and was touched by him, what a big loss!

Ah–!

Softly on his chest, listening to his pounding, strong heartbeat, her face turned red. Her greatest desire was to be in his arms.

She never dared to dream before, dared not wish for, and thought that in this life there was no such chance. This had been in her most secret heart of hearts, she longed for his warmth, longed for his love.

Even though he had hurt her before, he had given her more tenderness than others.

Being teased, loved, laughed at… had infiltrated into her bloodstream. Love, she did not know when it had taken root, for when she discovered it, it had grown into a towering tree, no longer able to be split open or cut off.

His hug, his warmth, she would not allow him to give it to others. If they were not only for her, she would rather not have them.
