If there is one good thing about Klaus, it is his dedication when it comes to his training.
He had always given his training his full attention, and at the moment, he was doing the same, making sure he got the best out of it.
Making progress on the path of the Law of Gravity gave him additional strength to seek even more power, and hopefully, he would be able to awaken the second seal on the 'Heaven's Engine' before he returned.
Meanwhile, back on Earth, the warriors were all in seclusion after each had received Klaus's blood.
Some had already taken his blood twice, so this third time was their third chance to become even stronger.
With Efad handing out the blood, every last person who entered seclusion was destined to come out as a monster.
Even the engineers and other non-warriors, but vital members of the Earth Alliance, were given some. With much bigger brains, they would be able to create things much faster.
