Rune 2

Under excitement, Yu Hong did not continue to reinforce the talisman array that night; usually, he would take out the talisman array for reinforcement every night, calculating the time needed and increasing the number of arrays, so they could be reinforced together and be ready by the next day.

But this time, he decided to test the Black Mark enhancement chamber.

With one hand against the stone wall, Yu Hong silently recited in his mind:

"Reinforce the entire safehouse; direction: add a new room, same size as this chamber, extending toward the mountain. Keep the exterior unchanged, enhance the door's strength, integrate seamlessly with the stone wall, and increase resistance to impacts."

A black line flashed, and a countdown appeared: 6 days, 9 hours, 42 minutes.

"Would you like to reinforce this chamber?" Black Mark's inquiry resonated.

"Yes!" Yu Hong responded expectantly.
