Once they had confirmed that Hua Min'er and the others could significantly strengthen the defenses of the array formations Ling Tian had set up by incorporating the Heaven Locking Pillars into the Externalized Small World, things became simple. While cultivating various secret arts, Hua Min'er and the others also made sure to nurture the Heaven Locking Pillars. After all, the higher their grade, the more effective they would be at strengthening the defenses. Naturally, they would also be harder to destroy when facing the Lord of the Universe.
Nurturing the Heaven Locking Pillars took time, and so did cultivating secret arts and improving their realms. Ling Tian and the others therefore hoped the Lord of the Universe would wait a little longer before launching the final battle. They knew, however, that the initiative lay with the Lord of the Universe, and there was no forcing the matter. Fortunately, they were in good spirits and were content to let things take their course.
Time drifted by. In the blink of an eye, more than a hundred years passed.
During this time, the Lord of the Universe did not attack Ling Tian and the others. The fact that he had delayed this long already satisfied Ling Tian greatly. In particular, with a thousandfold time acceleration inside the Eastern Emperor Bell's main space, the grade of the Heaven Locking Pillars nurtured by Hua Min'er and the others had improved considerably. Incorporating them into the Externalized Small World would further strengthen its defenses, and their higher grade would make them even harder for the Lord of the Universe to destroy.
"Heh, another hundred years have passed. Though your strength hasn't improved all that much, Ling Tian, it's still improved somewhat. More importantly, the Heaven Locking Pillars have risen in grade by quite a bit.
