The Greatest Beast Tamer of Earth

In the year 2050, a huge spaceship suddenly appeared above Earth.

The governments all around the world panicked as they saw the huge spaceship which was one fourth the size of the moon just teleported above Earth, Before they could even understand the situation, one 10 feet humanoid alien came out of it.

He looked like a giant human, but he had a divine glow surrounding his entire body. He had a crystal-like, light purple body that looked even 100 times stronger than diamonds.

He had dark purple long hair, which made him look like a Dragon Ball Z character.

He looked at the screen, and his golden eyes became visible. When he saw the confused faces of all of the humans, he smiled and announced,

"Humans, I am your ancestor Sage Kashyap." he said

People all around the world became surprised, they had many doubts like why are they so weak if they are his descendants and why did he come now when the whole Earth was in World War 3.

"We distributed our life code with an atmosphere changing module device to many universes and galaxies in the hope of recovering our numbers after the last Dimensions war. I wanted to give you more time to grow but the lack of mana have made all your souls, mana heart, brain and even your entire body regress every generation" he continued

People all around the world were shocked when they heard this alien's voice inside their heads again, they had many doubts like they always believed they were the only sentient beings in the entire universe. They were also interested in mana.

The alien laughed when he heard their inner thoughts and said:

"You really are our descendants; you do have the same sense of humor as us."

He then said in a serious tone, "Do you really think you all were born in this perfect environment because of luck?"

"Do you really believe dinosaurs died due to an accident?" he looked at the people again as if confirming if they were really his descendants.

He just wanted to continue when he saw multiple hypersonic missiles coming at him from all the directions. He showed an irritated look and then snapped.

In front of the people and all the governments all over the Earth, all missiles disappeared and then they saw them appearing behind the alien like an army of soldiers.

He pointed his hand towards the Earth and said in a serious tone this time "It looks like you think I am a joke"

He then continued while examining the missiles, "It's an interesting toy you people made with the limited resources you have"

He then smiled and continued "now take it back and remember this lesson while interacting with other species. Your weapon is powerful enough to give many alien species tough time if it hit them, but your ability to transport it is very weak"

He looked at Earth and said "You can do it like this" and pointed his hand towards Earth.

The lethal weapons known for chaos and destruction were usurped by an all encompassing portal, before re-emerging on earth's doorstep through lesser portals.

All people were shocked when they saw thousands of missiles striking towards earth's surface.

All the leaders around the world buckled and quivered in fear. when they saw thousands of their own missiles striking Earth.

All people around the earth panicked and closed their eyes and ears when they saw missiles, they even complained they were innocent and the leaders are responsible for this mess, but soon they noticed that nothing happened.

They browsed the internet to look at the scene again and were shocked to see, all missiles floating just 1 meter above Earth's surface before disappearing.

Sage Kashyap laughed and said "These nuclear weapons are fun, but I don't think you people need this toy, which does more harm than benefit to a planet."

He then chanted a spell.

People all across the Earth felt a change in the environment.

He then said, "I don't want all the work of the Supreme Creator to be destroyed because of your selfish reasons."

"As a result, I am banning the use of nuclear energy for you humans, You will not be able to use it like before." he said

"Now no one will be able to use any nuclear energy-related tools." he continued

All countries that had nuclear weapons were shocked when they checked and found out that all nuclear plants have stopped working, and if what the alien said is true, then they just lost their most powerful weapon.

The leaders of the countries which has nuclear weapons like US, Russia, China, India, and other nuclear countries had the look of disbelief and trembling legs.

The person who was most depressed was Rocket Man Kim Jong-un, he felt like his whole life was a lie.

Some country leaders celebrated when they heard that they do not need to fear the nuclear bomb anymore. They were Japan, South Korea, Ukraine and other countries without Nuclear weapons.

The alien looked at the sad faces of many country leaders and said:

"Don't make such sad faces just because you're losing this lower-level energy source. Think about how to use the new energy, called mana, effectively. It has multiple uses"

"I don't have much time, so I will keep it short. You guys need to return to your roots, as we need more people. You have not even become a Tier 1 civilization in 5 million years."

"The absence of a powerful enemy and the lack of mana on this planet have made you all weak. You would all bring shame to our name if I brought you back now."

"I will awaken the earth's mana core and install a dimensional dungeon system, which will open many portals all around the earth. This will make all of your lives difficult, The awakening of mana core of earth will also result in the awakening of other planets near Earth " he said, pausing.

People all over the world became depressed as they heard him speak. Some people thought will it make other planets habitable.

"Don't make such a sad face. This is important to make you all stronger in less time."

"Becoming stronger also has many benefits, like the fact that as you become more powerful, you will be able to increase your life span."

"You will also be able to stop getting older and even stop getting sick, and can also gain rewards like powerful spell, weapons and other exciting rewards as you clear your trials and become stronger."

"I'm also connecting your Internet to a smart and fair system, which will help you awaken faster and get strong enough to survive in our universe."

"The lack of mana for many centuries have blocked all of your meridians, suppressed your Magic organs like mana core, mana heart and other organs needed to use mana. This has also made you all unable to grow strong by relying on magic or physical power even without mana."

All people around the world made sad faces. They always thought they were evolving to become a more powerful specie but now did they realized they were regressing.

"Magic talent is hereditary, but your parents were also mortals, so how can they pass anything of significance to you?" he continued.

This broke the dream of many people who thought finally its their time to shine and now they could finally become a Wizard.

Sage Kashyap looked at their depressed look and said "That's why we have decided to help you mortals awaken one of the fundamental skills of our species, the Book of Contracts."

Some people were ecstatic about the prospect of becoming powerful, while others questioned why they needed to change their lives when they were content.

The alien heard their thoughts and laughed. Then he said:

"What makes you think that nothing bad will happen? If we can find you, then so can the other species."

"If other species discover you, you will all become their slaves and lab rats." he continued.

All the people got scared when they heard about the cruel reality. Then the alien smiled at their reaction and said,

"Don't think about them for now."

"I am sealing the space around this solar system, which will hide it from other species for 1000 years, after which it all depends on your luck and strength." he continued.

"Gaia (System AI) will explain the rest."

"Good luck! I have high expectations from you all. You all have a generous spirit, which will go well with "The Book of Contracts."" he said.

Then he snapped and disappeared with the spaceship.

Everyone was perplexed when they heard a voice in their heads say,

[Hello, Humans, I am Gaia, a system created by the Supreme Creator, Lord Brahma. I will help you all awaken and become strong]

[I will give the beginner's trial to all the people over the age of 10. Those who pass the trial will awaken the "Book of Contracts" and will be able to make contracts with level 1 Magic Beasts all around the world]

[Remember, one person will only have three chances to clear the beginner trial]

[To start the trial, please say "Awaken"]

Many people all around the world tried, and as soon as they said the word, a screen appeared in front of their eyes.

[Would you like to take the beginner's trial? Please respond with a yes or no]

As soon as the people replied with "yes" as an answer, they saw the text in front of their eyes change.

[Initiating beginner's trial]

Then they disappeared from their place as if they had never been there. All the people around them were shocked and decided to wait until they had all the knowledge.
