If Lu Shu's actual aptitude was one of his closely-guarded secrets, then his system and celestial map were secrets which he had to conceal no matter what.
Till this day, he still did not understand the use of that flame in his heart. The little sapling on his palm grew along with his strength, and now there were leaves on it as well.
Lu Shu wasn't sure what the flame would turn into. He didn't know what the sapling on his palm would become when he completed lighting up all the stars.
The only thing he could do now was to wait patiently and keep all his secrets close to his heart.
That scene made Lu Shu raise his guard once more. Lu Shu realized that the secrets within his body were far greater and deeper than what he had imagined.
Luckily there were so many people here so there was no need to exhibit so much of his strength.
