Even though Jaden had been able to react on time, he was not able to escape from the bullet completely. So, his shoulder was scratched by the bullet.
Still, Jaden was able to retreat behind the wall, and managed to dodge a fatal shot. And even though he could feel the pain from the bullet grazing past his shoulder, he felt relieved.
It was also at this moment that Jaden finally understood that even though he was currently strong, that did not imply that he was stronger enough to be able to ignore the bullets. If someone found him in an open space, and opened fire using an AK-47, he would definitely die.
Jaden took a deep breath, as he listened to the other party, preparing to shoot once again. It was clear that the moment that he showed himself, the guy would not hesitate to attack him at all.
Having understood that, Jaden retreated. He looked around, before finding a shelf not far away from where he was. On the shelf, there were several books.
