A burst of white light flashed, and Li Shang actually returned to Sky City. Xiong He stood in front of him, but Li Shang had a feeling that she was not the one he knew.

"Where is this?" Li Shang asked.

"This is your world." Xiong He replied: "I am Xiong He fifty years later, not Xiong He at that time, I know what you are looking for." ”

The ground around him slowly shattered, and the Sky City was actually shattering.

"There is no cure for this world. I decided to destroy it with my own hands. Xiong He said coldly: "But fifty years ago, there was still a naïve me, I hope you will save her." ”

"I will, but how?"

"You go to a place with me first, and I'll show you the origin of everything." As he spoke, the world around the two of them quickly regressed, but only the two of them remained the same.

"You should know that when a choice arises, different choices will create different worlds, which is also the theory of parallel space." Xiong He said.

"I know." Li Shang replied.

"Before I was born, my mother's family was very good, but my father's family was not good, he was just a poor teacher. For my mother, it was a choice whether or not to marry my father, and it created two worlds. There was a world where my mother listened to the family around her and did not get married, so in that world, I was not born. In one world, my father and my mother got married and gave birth to twins. ”

With that, the timeline came to the very beginning.

In this world, Papa Bear has a wife who loves him very much. He had twins, a boy and a girl. The female is called Xiong He, and the male is called Xiong Xin.

On this day, the two children turned six. They were playing hide and seek at home, and Xiong Xin hid under the bed, waiting for Xiong He to come and find him, when suddenly a white light burst out.

Papa Bear from another world has arrived. It turned out that in another world, Daddy Bear did not marry the person he loved, he became more assiduous, and became a rich businessman step by step. But at the price, he lost his children forever.

So he hired a group of scientists to develop a device for him to another world, and he brutally killed Daddy Bear and his wife in this world, and captured Xiong He to another world. But Xiong Xin survived because he hid under the bed, until he was discovered by the police, and Captain Li of the criminal police team adopted him and changed his name to Li Shang. With the support of his father, Li Shang embarked on the path of mercenary and became an internationally renowned mercenary captain.

Until he was 21 years old, his father died, and before he died, he told him the secret that he was not his own, and Li Shang gradually became depressed and became an alcoholic and gambled. After that, he was discovered by an arms dealer and taken to another world.

"So we're brother and sister?" Li Shang asked.

"It's brother and sister." Xiong He said angrily: "You know everything now, if you don't change this timeline, I in the other world will be imprisoned in the Sky City because I have lost my power." Papa Bear, on the other hand, continued his reign and was killed by the rebels fifty years later. In that world, the earth will deteriorate to the extreme, and virtual projections will no longer blind people, but the earth will be hopeless. So it will eventually perish. I don't have much power left now, and you only have one chance, to go back to a time you want to go back to, and save humanity. ”

"Only once?" Li Shang confirmed it again.

"Once."

"Then you teach me how to operate the nightingale first."
