Qi Zhiheng returned to his house in the herb garden and entered the attic in the space, preparing to find a way to shield his great-grandfather from the lightning tribulation.

I finally found the Hidden Thunder Array among a bunch of array books. This array is also divided into levels. The Hidden Thunder Array is used to hide the lightning tribulation attracted during the Foundation Establishment stage. To put it bluntly, it is an illusion array.

Qi Zhiheng studied the formation and discovered that it was truly intricately linked, with each element interconnected! It was incredibly profound and exquisite...

Okay! Actually, he just doesn't understand it! He'd rather refine a hundred batches of medicine than study this book on formations!

Qi Zhiheng took the book on formations to his father. Formations were too difficult; it was better to let his father handle it. After all, his father was the pillar of the family. Who else could they rely on?

Qi Zhiheng comfortably shifted the blame! He still had health issues to address!

Back in the front hall of the house, Qi Zhiheng found his family there. He exclaimed, "Father! I've found a way to shield myself from the lightning tribulation!" As he spoke, he stuffed a book on formations into Qi Zhenhe's arms.

Qi Zhenhe opened the book, glanced at the contents, and turned the pages without saying a word.

After an incense stick burns...

Qi Zhenhe suddenly spoke up: "Father! Come and take a look at this book on formations!"

Qi Zhiheng thought to himself: Sure enough, his father is amazing. He couldn't understand the array book after reading it for a long time, but his father found the crux of the problem in an instant!

Qi Dong asked, "What's wrong? What happened?"

Qi Zhenhe said matter-of-factly, "It's nothing, I don't understand it at all, I'll leave it to you, Father!" After all, he was his father!

Qi Dong reluctantly accepted the book on formations. He wasn't interested in any formations; he just wanted to focus on growing and refining herbs!

Qi Dong flipped through two pages, feeling utterly overwhelmed.

The three men in the house sat facing each other, staring at each other.

Yang Yao suddenly spoke up: "Let me see the book."

Qi Dong always listened to his wife and immediately handed her the book on formations.

This is a beginner's book on formations, and the content is relatively simple, but the men of the Qi family seem to have no affinity for formations.

After Yang Yao took the book, the family went about their business.

Qi Zhiheng didn't have much hope for his grandmother's desire to learn the book on formations. After returning home, he wanted to see if there were any other ways to resolve the tribulation.

After searching all day without any results, Qi Zhiheng was somewhat discouraged. Did he really have to continue studying those messy arrays?

Qi Zhiheng returned home with a heavy heart.

However, Qi Zhenhe's face showed no sign of distress.

Upon seeing Qi Zhiheng, Qi Zhenhe took a sip of tea and smiled slightly, saying, "Zhiheng, you've come."

Qi Zhiheng asked, "Father, you look so happy, is there some good news?"

Qi Zhenhe did not answer his question directly, but smiled and said, "Come with me."

The two went to the backyard.

Qi Zhiheng could hear Qi Dong flattering Yang Yao from afar: "Wife! You're really amazing..."

Qi Zhenhe called out, "Father, Mother."

Qi Zhiheng also called them grandpa and grandma.

The two approached Yang Yao, and Qi Zhiheng noticed that Yang Yao was fiddling with some stones and flags.

"This is..." Qi Zhiheng exclaimed, his eyes widening. "A battle flag!"

Qi Dong said proudly, "This is all thanks to your grandma! We should be able to set up the Hidden Thunder Array in a couple of days."

Qi Zhiheng was also shocked! He never expected that his grandmother was not only good at handling domestic affairs, but also learned formations so quickly! He had been troubled by not being able to find a substitute for formations, but now he had finally solved a major problem!
