Duckweed Lake was covered by a natural concealment array, which greatly interested both Ye Haifei and Ye Yunshan.
Ye Haifei was especially interested. He was also a sixth-stage array master, second only to Ye Jingyu in the Ye Family in his mastery of arrays.
He was eager to study the array. Although he only had about a month left before descending to the lower realm, he would study it for as long as he could.
He might need to set up arrays in the Mortal Realm, after all.
He could record it now and study it in the Mortal Realm later.
That would make the hundred-year term less difficult to endure.
Ye Jingcheng took out a jade token and began forming hand seals.
The jade token immediately filled with spiritual light, which spread into the surroundings.
At the same time, the water level in the lake began to fall.
Miraculously, the spirit fish placed there earlier suffered no harm as the water receded.
Before long, a single droplet of water was revealed.
That droplet was none other than Water Heaven.
"It seems Water Heaven is dead." Unable to sense Water Heaven activating Treasure Radiance, Ye Jingcheng could not help sighing.
For the Ye Family, the more large grotto-heavens like this they had, the better. If it could advance, that would be even better.
Of course, even if it could not advance, they could still use it to advance the Blood Spring.
They simply had to handle it properly, or they would destroy a grotto-heaven.
"Come on, let's take a look inside together!" With that, Ye Jingcheng took the lead and flew toward the grotto-heaven.
Ye Haifei and Ye Yunshan followed behind him.
But the moment he entered the grotto-heaven...
Ye Jingcheng saw a streak of mysterious light slash toward him.
