After leaving the hospital, Zhang Shu sent his sister back to Li Guohui's house.

After lunch, I said hello and said that I would go out for a walk and stop by to see if there was a suitable job.

Seeing that Zhang Ji's spirit had recovered a lot, Li Guohui was also a lot more relieved, thinking that it would be good to go out and go around, just to get familiar with normal life, so he didn't say anything to stop him.

Walking on the crowded streets, Zhang Ji thought about the next road in his mind.

First of all, my sister's school expenses are the most urgent, and the school is about to open in half a month.

Yancheng University has two semesters a year, and each semester requires a tuition fee of 10,000 federal coins, plus Zhang Xiaoting's living expenses for four years, and almost 100,000 federal coins have to be prepared for the whole time.

Even if you can pay it annually, you need to make up the part of the school fee within half a month, at least 30,000 federal coins, and at this time, the entire savings of the booklet are less than 3,000 federal coins.

In his thoughts, Zhang Ji suddenly felt a shade, and couldn't help but stop, just thinking and walking, he unconsciously came to the door of a building.

Compared to the street just now, the crowd density around here is almost half, and when you look up, the name of the building is written on it - [Federal Imperial Guardian Association].

In the lower right corner is a line of small print, Yancheng Branch.

Zhang Ji exhaled deeply, it seemed that he had subconsciously already known the answer, and if he wanted to get 30,000 federal coins in half a month, he was probably the only way he could get his hands on it.

That is to become a [Guardian]!

The Guardian is a profession born out of the global crisis three years ago.

And those three years of difficult history were a great turning point in the fate of mankind.

The first year of the great upheaval is known as the year of calamity.

On the first day of January, twelve mysterious space cracks appeared out of thin air on a global scale without warning, and the world fell into a huge shock that it had never seen before, and the existing worldview was overturned in an instant.

However, twenty-four hours after the incident, the unusually deep spatial rift suddenly broke the peace, and many unimaginable terrifying monsters emerged from it!

Horrific monsters have wreaked havoc around the world, killing and wounding humans in a short period of time, with mortality rates reaching their highest level in hundreds of years.

In the face of a terrifying catastrophe that can affect the survival of all mankind, in just three months, the countries of the world quickly formed a global federation of common defense and defense fronts, and all decisions were made by the world's only authority [the Supreme Council of the Federation]!

With the establishment of the Federation, the passive situation in the world gradually began to retract, and the power of all mankind was revealed at this time, and during this period, an incredible mysterious phenomenon was unearthed.

When a human touched a dead monster with his body, the monster's body gave birth to a strange light and quickly retracted, finally turning into a mysterious template the size of a palm.

This process is like the laws of two different worlds, interacting in this moment!

And then, after the human picked up the monster template, he found that he could actually control the template, release the monster, and control the monster to make any commands!

The monster that was released lost its memories and scars, leaving only some instincts such as fighting and roaring, and this discovery led to the creation of a new combat power in the Human Federation that manipulated monsters in battle, the Guardian!

Under the countless Federation soldiers and Imperial Guards fighting regardless of life and death, the human race finally repelled all the monsters that emerged from the twelve spatial cracks on the last day of the Calamity Year.

That night, the Federation announced to the global human race through video conferencing: The war between humans and monsters is over at this moment!

The atmosphere of celebration filled every corner of the world, and people were in tears and hugged each other.

However, it seems to be a joke made by the infinite universe.

After dawn, thousands of spatial cracks, like nightmares, appeared madly all over the world.

The second year, known as the Year of Chaos, began.

An astonishing number of monsters have frantically poured into the human world.

After the initial chaos, the mature [Supreme Council of the Federation] quickly adjusted the situation, and issued various orders without interruption, mobilizing all the combat forces of the Federation to fight back with all their might!

Humanity will not be easily exterminated!

When the fighting spirit of all mankind was aroused by a huge number of monsters and engaged in a brutal struggle, the situation in the world became more and more stable.

Humanity has gradually gained an advantage in the protracted war, thanks to the emergence of the powerful combat power of the Imperial Guardian, coupled with the large-scale use of technological weapons, the human race has quickly repelled the invading monsters during the year, and built solid and towering military fortresses around each spatial rift, isolating it from human habitation.

As long as more monsters emerge from the spatial cracks, they can be blocked and killed in the fortress as soon as possible!

After the completion of this huge project, the Federation made a sensational decision to take the initiative! Organize battles and researchers to enter the cracks in space and explore the origin of the disaster.

After entering the mysterious world, human beings found that the firearms and technological weapons of the original world had completely lost their effectiveness here!

Only the ability of the guardian can still be used without damage, and what is even more surprising is that the same monster in the other world is much more powerful than the one that appears in the current world.

Moreover, with the subsequent exploration, it was discovered that after the monster killed the human, it was able to increase its own strength, and after a human exploration team was killed, that monster evolved a more powerful ability!

It's like a pact between two worlds!

When humans kill monsters, they can have a monster template and become a guardian.

Monsters killing humans can directly increase their own strength and evolve to become more powerful.

However, neither side can use weapons or abilities far beyond what is known in the other world.

After finally figuring out some of the laws of the other world, human beings launched a reverse struggle, and also built solid barriers around the spatial cracks in the other world!

In this way, humanity has moved the front line of defense against monsters to another world, resulting in peace and stability in the current world, which is an even more difficult human project.

The two barriers in the two worlds, each surrounding the same spatial rift, are like a [verandah] recorded in light years, with the present world at one end and the other world at the other.

At this point, mankind has achieved a phased victory, and the world has finally ushered in a short period of peace.

Then, the world ushered in the third year known as the Year of the Riots.

The situation that was basically stabilized by the Federation suddenly underwent unpredictable changes, and the number of global space rifts began to increase at the original rate of several times!

In just a few months, the number of new spatial cracks has reached the increase of last year!

As a result, the Federation's original combat power has been somewhat compromised, and the [Supreme Council of the Federation] urgently issued a new decree to allow all citizens of the Federation to become guardians on their own, and distribute monster templates to encourage them to defend their homes against monsters.

As soon as the decree was issued, a wave of the era of the Imperial Guardian was immediately set off, during which many powerful and spontaneous Imperial Guardian forces rose.

That year also caused the breakdown of many families, and Zhang's home was also destroyed in the riots.

The crack that exuded purple-black spatial power, the hideous monsters that rushed out of it, the blood all over the room, and the two figures who desperately stood in front of him.

Shaking his head vigorously, he stood in front of the gate of the [Federal Imperial Guardian Association], dissipated these memory fragments from his mind, and walked into the building in front of him with a determined look.

In the middle of the hall, at a row of electronic devices full of technology, the album stopped.

Standing in front of an independent device that can apply for the qualification of the Imperial Guardian, he slowly pressed the application button on the screen.

"Ding!"
