The charge drum is a preparation for group combat.

It only works if humans hear it, that is to say, as long as humans hear it, it will work!

This war drum is obviously not suitable for human infighting, but is specially made to deal with zombies.

The final imperial seal is what really moves him!

Absorb the royal energy of the world?

Wouldn't that be a good opportunity to improve your own mark?

Moreover, the Tang Dynasty royal family did not discover the use of royal energy, and only used it as a symbol of imperial power. Doesn't this mean that the royal energy in the jade seal has never been consumed?

Picking up the jade seal, the mark on the back of his hand immediately flashed silver!

The power of the seal resonates with the royal aura within the jade seal.

Suddenly, a rich royal aura emerged from the jade seal and transformed into a huge illusory golden dragon. With a long roar, it drilled into the mark on the back of Ao Xin's left hand!

The seal gradually became perfect, and this jade seal absorbed all the royal aura in the world.

The amount contained is enormous.

It took the golden dragon several hours to completely integrate, and the mark became more and more complete.

At this time, Ao Xin finally figured out what the mark was.

That is the character "王"!

Moreover, the bottom horizontal line is already one third completed!

His talent for domineering color has been greatly improved. Because he possesses domineering talent, he can almost vaguely feel the slow growth of the domineering color power in his body!

The imperial seal was handed over to Ao Chen. Although the royal energy inside had been completely absorbed by him, after leaving the secret realm, he could still use this seal to absorb the royal energy from other ancient cities on Blue Star.

He had only searched all the ancient cities in Yuzhou before, and it was obviously impossible that Yuzhou was the only city with royal aura!

After storing all the items in the underground space into Ao Chen's treasure space, Ao Xin summoned a flame cloud, and the two of them flew back to the ground on the flame cloud.

The trip to Chang'an ended successfully. They first found Zhang Wenqian and her group, took Liu Jingshan with them, and flew south.

He first had to go to the ruins of the ancient city of Shendu to pick up Zhou Xingjian.

In the sky, Liu Jingshan, who was riding on the Flame Cloud for the first time, felt a little nervous.

Although the young man in front of him was more than 20 years younger than him and was the son of his former college roommate.

But the sense of oppression that Ao Xin brings is extremely strong!

His powerful domineering aura gave him the majesty of a king, and even if he just stood there and said nothing, people would still feel awe.

This feeling was even more stressful than when he first faced his mentor or when he first started working and faced the company boss!

He sat there silently, not knowing why Ao Xin wanted to take him away.

Ao Xin didn't say anything except telling him that he was Ao Kang's son, which made him feel a little uneasy.

Fortunately, Ao Chen was quite lively and she took the initiative to talk to Liu Jingshan.

"Uncle Liu, tell me about my dad's college days!"

Ao Chen rolled his eyes and said with a grin, "For example, did he have a secret crush at that time?"

The corner of Ao Xin's mouth twitched when she heard this. If her father knew that Ao Chen was asking about his gossip behind his back, the little girl would be beaten.

He once again summoned a flame cloud and placed it under his neck. He lay comfortably on the cloud with his eyes closed, while also listening to the gossip about his father in the past.

"Your father, he was..."

There was a look of reminiscence in Liu Jingshan's eyes. His college days were more than 20 years ago.

"Your dad was the most handsome boy in our school back then!"

Liu Jingshan thought of the handsome boy back then. Now seeing the looks of Ao Xin and his sister, he found that they were even better than his father!

I think Ao Kang’s wife is also a school beauty.

When Ao Kang got married, he was invited. Unfortunately, he was in America at the time, doing a very important experiment with his supervisor. He didn't have time and therefore didn't come back.

Unfortunately, the Internet was not well developed back then and they didn’t have a group, otherwise they would have been able to see Ao Kang’s wedding photos.

After chatting with Ao Chen for a while, his nervousness disappeared a lot.

At least, judging from the attitude of his daughter Ao Kang, it was not a bad thing for them to take her away.

Ao Chen laughed as he listened. It was the first time he heard many of his father's embarrassing moments in college.

When they were having dinner together in the evening, Liu Jingshan dared to ask them why they took him away.

Ao Xin said, "To be honest with you, Uncle Liu, I'm also a medical student. I often hear my father talk about you at home. He says that your achievements in pharmacology are among the best in the world!"

Liu Jingshan quickly said modestly, "You're too kind, too kind. I'm just luckier."

Ao Xin said:

"We found many medicinal pills in this secret realm, and we even have the recipes and refining methods!"

"But the technology is from the past after all, and this secret realm is obviously different from our ancient times. It's more like a fantasy version of a parallel dimension, so it's not easy for us to fully master these methods."

"You happen to be very knowledgeable in pharmacology. Would you be willing to help me research these pills?"

Liu Jingshan immediately replied, "Yes! This is within my professional scope. However, I don't have the equipment, so it's difficult for me to perform medicinal analysis."

Ao Xin took him away, so he had no choice but to agree.

Moreover, studying this mysterious elixir was exactly what he was interested in. Otherwise, as the top-performing clinical medicine student in the school, he would not have pursued a pharmacy degree at the same time and eventually chosen to be a pharmacy graduate student.

"We'll arrange the equipment for you after we leave the secret realm. Don't worry."

Ao Xin had originally planned to rebuild the power system and set up a laboratory in the Beast Base after leaving the secret realm. Ao Kang had been preparing for this for a long time.

"My father moved all the medical equipment out of Biancheng a while ago. There should be what you need. For the rest, we can go to other cities to look for it. If that doesn't work, we can find a way to make it. It's not impossible."

When one's strength increases, manual labor can often replace machinery. However, rebuilding those high-precision experimental equipment requires more than just physical strength.

We need to find more professional talents.

But don't worry, his reputation has already been established. When the time comes, if you invite him, there won't be many people who will refuse!

Well...it's no use refusing. If you force me to come here, this is not a society ruled by law!

As for whether the original forces of those people will release them?

Ao Xin felt that this was the easiest problem to solve.

After flying for several days, they finally arrived at the ruins of the ancient city of Shendu.

At this moment, Luo Qingyan was leading his subordinates to fight against a wave of zombies.

Popularity will attract zombies, and no matter how far away the zombies are, they will smell the scent of living people.

The army of martial corpses led by dozens of spirit corpses made it very difficult for humans to fight.

However, after a few months of development, their strength has also improved significantly.
