For a few seconds, David did not open his eyes and was ready to accept the pain. But surprisingly, he did not feel any pain and did not hear any explosion or anything like that.
Only then did David decide to open his eyes. But he was surprised. In front of him he can see a person that he is familiar with.
That person is the first Warrior he rescued and beside that person he can also see there are many other Warriors from the Warrior Association.
The moment David realizes what is happening, he is unable to maintain his consciousness. As you know all this time, he kept him away using his full willpower.
But the moment he noticed the warrior from the Warrior Association came to that place, he was unable to maintain that consciousness. Somehow, his tense body became relaxed and, with this, he was unable to maintain consciousness.
