Hero Zhang Han was frustrated in life originally, but he stepped into the Cultivation World by a stroke of luck. Possessing divine natural gifts, he ascended into the disaster-crossing period step by step. He had imagined his life would not have any hardships anymore, but unfortunately incurred the god thunder since he violated the fate. After he woke up, he was surprised to find that he was reborn, going back a few years ago. He found that the world was different from what it used to be after his rebirth and he had a lovely daughter.

For the man’s promise, Xiao Chen returned strongly, the bodyguard of the body of the beauty president, sweeping the enemy of all directions, composing the legend of the king!

Tibbers’ confession:

I am a shadow bear! An extremely powerful shadow bear! A shadow bear that is expected to become the king of shadow bears in the future!

I am arrogant in the shadow world! Bullying the male and the female! No one dares to oppose me! Because the bear or other creatures who opposed me are dead!

However, I never expected that I would fall into the hands of a two-year-old human girl!
It was a sunny afternoon…..Forget it, let’s not mention that day!

I was forced into a contract to become a teddy bear without bear rights! She named me Tibbers!

The one thing I want most now is: more unscrupulous creatures to provoke my master, so that I can often come out and let go…
