MTL - Please Smile at Me - Chapter 44 "Nightmare"

An alien race invaded the Earth on June 6, 2128. At the midst of this war, many nations allied with the alien threat and the war nearly wiped out the rebelling humans of the planet. At the edge of mankind's survival, the United Nations Army launched its forces to eliminate the immediate stellar threats that loomed over Earth.

General Seeker Carlean, commander and leader of the mission, risked and gave his life to destroy the immediate stellar threat. The battle was won though Earth lay in ruins. Perhaps mankind will live to see a few years of peace before the alien threat returns to wipe out their existence.

At the immediate aftermath of the stellar battle, the fallen Seeker Carlean awakens and finds himself at aged 17, living the peaceful life he lived 16 years before he died.

So begins a new game in the battle for humanity's survival.

Qin Tian accidentally transmigrated into a sickly body, a body with broken Dantian that was unable to practice Qigong, in another world. Fortunately, God had mercy on him by giving him a level up system. Useless? That was him in the past. Not worrying about practicing Qigong, he was now able to kill Monsters to level up. Easy! Level up when killing Monsters; level up when killing people. An unbeatable sovereign of the clan in the eyes of other people, but in his eyes, he is a glittering big BOSS.

After dedicating her life and curing the sick male protagonist, Jin Hua realized that she was living in a book, and she was the female cannon fodder who burned herself and illuminated others.

Since her death, the male protagonist finally learned to love himself and others, and then tearfully spoiled the female protagonist who was six or seven similar to her, becoming a model couple that everyone envied.

After the rebirth, Jin Hua didn’t want to sacrifice herself to pave the way for others, and took the initiative to hug the thigh of the villain Bamboo Horse, the man who forced herself to be the villain for her, and was finally made insane by the combination of the hero and heroine.

In this life, Jin Hua only wants to stay away from the plot line of the hero and heroine. The goal in life is to chase after Jian Huaiyu, love Jian Huaiyu, and love Jian Huaiyu.

Jian Huaiyu’s life creed is: love Jinhua, love Jinhua, or love Jinhua, love her to heaven.
