MTL - The Mightiest Leveling System - Chapter 4 Crazy upgrade

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.

One of the world’s top killer who was fed up with his life tried to retire and live as a security guard at Jiang Yuan University. He only wanted to adapt to the life of an ordinary citizen and blend into the society. However, he didn’t expect that a random encounter with a beautiful girl, who was also the prettiest girl in the university, will become the key to a fierce pursuit, and at the same time, all kind of beautiful women, as well as powerful enemies came into his life.

Let’s watch over the journey of this Versatile Security Guard. Let’s see how he will obtain various beautiful flowers and eliminate his enemies and step on the head of powerful villains.

I only wanted to be a small security guard, Xu Taping said while lying in the lap of a beautiful flower.

Jiang Chengxuan accidentally traveled to the world of cultivating immortals, and accidentally obtained the inheritance of cultivating immortals.

However, the aptitude is really low, and he has been practicing hard for a hundred years, but he still cannot be promoted to the foundation building state.

Just when he was disheartened and silently came to a mortal city, ready to end his life here, Goldfinger finally arrived belatedly.

It is detected that the host has achieved the achievement of cultivating immortals for a hundred years, and I hereby reward one longevity fruit, which can increase one’s lifespan by serving it.

The next achievement task is now posted.

Ask the host to clear the level a hundred times. After completing it, you can achieve the achievement of breaking through the level one hundred times, and you can get one chance to successfully clear the level.

Ding!

Ask the host to complete a hundred times of spell practice, and if you achieve it, you can get a jade talisman for the inheritance of the perfect spell.

Ask the host to complete the achievement of making talismans a hundred times…

Ask the host to complete a hundred enlightenment achievements…

Please host…

Unknowingly, when Jiang Chengxuan heard the prompt from the system again, he was told that there is no achievement worthy of you to complete, because your existence itself is already an achievement that can never be surpassed.
