As Light Elves, they looked down on Night Elves. Their good upbringing prevented them from deliberately bullying Estelle, but it was impossible for them to approach him and offer him help.

Yu Huang and the others could understand a portion of the Night Elves’ language, but they didn’t know how to speak their language. Therefore, even if Yu Huang wanted to help Estelle, she had no way to do so.

When Estelle saw that no one was willing to help him, he felt ashamed and sad. His hands were twisted together, and his eyes were filled with sorrow.

At that moment, a gorgeous voice came from the Light Elf group at the front. “Come to me.”

Estelle looked up in shock at the Light Elf at the front of the crowd.

It was Donor.

On the second day after Estelle entered the Holy Spirit Academy, he learned Donor’s true identity. After knowing that this handsome and noble Light Elf was the prince of the elves, Estelle no longer spoke to Donor so casually.

The lowly and ugly Night Elves didn’t even have the right to look at the Elven Prince directly. Estelle naturally didn’t dare to dream of being friends with Donor.

But when he saw Donor giving him a kind signal, Estelle suddenly felt a little bitter.

He silently walked through the crowd and sat beside Donor. He carefully pressed the corner of his shirt under his thigh to prevent his rough and tattered fabric from dirtying Prince Donor’s silk pants.

Donor noticed Estelle’s small action and said nothing. He just straightened his back and listened attentively.

The Light Elves sitting at the back were furious when they saw this.

How could that lowly Night Elf sit beside Prince Donor?!

Prince Donor was too kind.

The Light Elves wanted to persuade the prince to stay away from the Night Elf, but because it was class time, they could only endure it.

When Pupu An saw that Estelle had found a translator, he nodded in relief and continued, “Although the Sky Penetrating Array is the most basic type of sacrificial array, it is also the most unique type. Since the creation of the sacrificial array, only the Sky Penetrating Array hasn’t been successfully set up. Does anyone know the reason?”

The students had memorized all the array formations, but the book didn’t explain the principle of the Sky Penetrating Array in detail.

Therefore, when Pupu An raised this question, no one raised their hands for a moment.

Yu Huang had some understanding of the array. She was about to raise her hand when she saw Sheng Xiao raise his right hand.

Yu Huang lowered her right hand.

Pupu An nodded at Sheng Xiao. “Sheng Xiao, please speak.”

Sheng Xiao said in a low voice, “Because although the Sky Penetrating Array is the simplest and most basic array formation, it is only a theoretical array formation. As far as I know, the person who proposed the Sky Penetrating Array was called Black Mountain, a Prime Master from the Cang Lang Continent three thousand years ago. This Prime Master spent his entire life researching sacrificial cultivation techniques. Before he died, he created a theoretical array formation. It was this Sky Penetrating Array.”

“According to the explanation of Prime Master Black Mountain, everyone can use the Sky Penetrating Array, but no one can successfully set it up. Because…” Sheng Xiao looked up at the blue sea and clouds above his head. He said,” The Sky Penetrating Array needs at least four Prime Masters and a thousand Grand Masters to activate the power of the formation. ”

In the three thousand worlds, no one had successfully ordered four Prime Masters and a thousand Grand Masters to sacrifice themselves.

Therefore, no one could use the Sky Penetrating Array.

Pupu An looked at Sheng Xiao in admiration. Di Ruofeng crossed his arms proudly and gave Sheng Xiao a look of approval.

There were 500 students present, but only his student knew the answer. How could he not be proud?

“Sheng Xiao is right.” Pupu An extended his index finger. A wisp of white spiritual power emerged from his index finger and landed on the ground before turning into a spiritual power bead. Then, Di Ruofeng extended his index finger and released his spiritual power.

Their spiritual energy beads mixed together and became an even larger spiritual energy bead.

Pupu An stared at the spiritual energy bead and said, “The so-called Sky Penetrating Array is about gathering four Prime Masters and a thousand Grand Masters and making them willingly sacrifice all their spiritual energy. Their spiritual energy will be like this spiritual energy bead. It will accumulate into a tower and successfully build a bridge to the sky.”
