"By the way, what is azure gold?" Asked the fat man.

He has personally experienced the strength of the four golden lock arrays. If he can learn this array and find the materials he needs, it will be of great use at the critical moment.

"It's a rare kind of refined gold and silver, but it should be sold in the capital. I'll look for it when I go back." Gu Fenghua replied.

She had learned the array with her brothers for a long time. Although it was difficult for her age, she had a better understanding of the array than ordinary people.

The next journey, several people did not idle, while practicing, while studying the four golden lock array. As soon as they got to the capital, they finally studied the array thoroughly.

Only then did they know that this array had to rely on their own holy spirit to motivate them. With their current strength, if they set up the array alone, they would not be able to give full play to their power. Only when four people join hands can they give full play to the power of the array.

Fortunately, they are friends who live and die together and can hold their backs to each other, so it doesn't matter.

After studying the array thoroughly, a few people had nothing else to do and went back to the capital with ease.

Originally, several people should go to the college to report after finishing their training, but thinking about Liu Zihan, Gu Fenghua went home first. The carriage drove to the middle of the way, and Bai pangzi and others also went home. After all, I'm only a teenager. I feel homesick after I've been away for such a long time.

"Miss is back. Please report to your excellency. Miss is back." As soon as he saw Gu Fenghua coming back, the porter cried excitedly.

"Miss is back, miss is back..." then, the prime minister's house was full of cheers.

"Fenghua, you are back!" Without waiting for the news to reach the study, Gu Tianci walked out of the hall quickly.

At this time, he should have stayed in his study. The reason why he stayed in the hall was obviously that he was waiting for Gu Fenghua to come back every day and wanted to see his baby granddaughter at the first time.

"Grandfather." Gu Fenghua was moved. Looking at his grandfather's white temples, he felt sad. If she hadn't grown up, she would have bumped into her grandfather's arms as a child.

"Just come back, just come back." Gu Tianci looked at Gu Fenghua with tears of joy in his eyes.

"I've suffered a lot in this training. Look at how thin you are." Gu Tianci looked at Gu Fenghua's face and said painfully.

"I didn't suffer much. Actually, I'm fat." Gu Fenghua embarrassed said.

After sitting in the carriage for such a long time and eating the meal carefully prepared by the fat man every day, she is actually a little fat. But in my grandfather's heart, I will always be the child who has to feed and can't grow fat without feeding.

"It's better to be fat. It's better to be fat. If you hadn't grown up, I'd like to feed you more fat." Grandfather said with a smile.

Gu Fenghua is secretly glad that he has grown up.

Gu Tianci looked up and down at Gu Fenghua. Seeing that she was as good as before, and there was no sign of injury, he was relieved. His eyes turned and fell on Liu Zihan: "is this little girl?"

After only one look, he couldn't move his sight any more, and his eyes were full of doubts and surprise.

Liu Zihan is not comfortable with him. He hides behind Gu Fengyun, but he can't help but peep out his head and look at Gu Tianci. His eyes are also full of doubts.

"Grandfather, let's go back to the study." Gu Fenghua thought of the strange feeling when he saw Liu Zihan for the first time.
