"Runish formation?"

Amelia was stunned for a moment.

"I know a little, but I don't know much about it..."

From the corner of her eyes, she saw Xu Nuo's brow frowning unconsciously. She seemed to have thought of something and quickly added.

"I remembered it! Victor once obtained a book related to rune formation, which seemed to be obtained at a great price. Which of our dormant places was created by this book!"

"Books related to rune formation?"

Xu Nuo's heart moved slightly.

“Where is it now?”

"Victor attaches great importance to it and specially built a secret room to store it on the second floor of the underground. However, I am not sure if it is still there in the current situation of Victor Castle..."

"Let's go and have a look now!"

Xu Nuo made a quick decision and made a decision.

So he went out again not long after he came back.

During this trip, Xu Nuo didn't want the extra people to know, so he only brought Amelia and asked the remaining people to cover up. No matter who comes to him, he will never be able to see him.

So and this way.

Xu Nuo and Amelia quietly left the Connors Five-Star Hotel.

In order not to find traces, they directly chose to walk from the underground passage.

With ultrasonic detection, he controlled the environment within a radius of ten kilometers. He knew the specific situation without knowing much in advance, so he didn't have to worry about being discovered.

However, considering what was discovered by two other legendary powerhouses before, Xu Nuo did not open the ultrasonic detection to the maximum, but only maintained a range of about 500 meters.

This time the action is very important and will likely determine the outcome of the final battle. Xu Nuo does not want anyone to know, especially when he now suspects that he has an "undercover" side, some things should be more cautious.

Ultrasonic detection is only capable of being able to be sensed before, but now someone can sense it, and one of them is likely to be the second leader of the villain, so it is not too much to be cautious.

Xu Nuo walked forward all the way in the underground world, and it was fine for the first 500 meters, because of his previous behavior, there was no one who followed within a radius of 500 meters.

But it's different from five hundred meters away.

The royal family and the four legendary families all sent people around.

Logically speaking, Xu Nuo has agreed to a dinner party as the representative of the four legendary families, and also to a party from the royal family. This kind of stalking behavior against him should be reduced or even disappeared.

But in fact, this is not the case.

After Xu Nuo agreed and even participated in their invitation, the number of these stalking not only did not decrease, but increased a lot! It was as if I was afraid that he would suddenly disappear!

Five hundred meters away from the Connors Five-Star Hotel, both on and under the ground, there are people from the royal family and the four legendary families, and they are not ordinary people, all two-star or even three-star extraordinary people.

Not only that, they even brought several ultrasonic detection equipment here!

This is the terrible thing about the national power.

No matter what type of extraordinary ability you have, as long as you are discovered at the source, there will always be something that can target you.

This ultrasonic detection device is just one of them.

It is said that at the British Empire Research Department, a project has been launched to study equipment for infrasonic waves!

Once successful, Xunuo's ultrasonic ability will not be completely destroyed, but it is very likely that it will be weakened a lot.

At the same level, people bring special equipment and gain a few advantages before they start fighting. How can you fight?

When Xu Nuo first discovered these ultrasonic detection equipment, he couldn't help but be shocked.

I wasn't discovered just after I came out, wouldn't I?

It was not until later that he realized that he was overthinking.

His ultrasound was not detected.

This is not to say that there is something wrong with their ultrasonic detection equipment, but because Xunuo's ultrasonic waves have reached the level of four-star lv·4 and have a certain amount of extraordinary power. They cannot be detected using normal ultrasonic detection equipment.

Xu Nuo’s ultrasonic detection can even be deceived by ordinary legendary powerhouses. How could these ordinary ultrasonic detection devices be able to detect it?

"But...this is now. If one day in the future, these ultrasonic detection equipment will make breakthroughs and become extraordinary equipment that can detect extraordinary power, it will be different."

Xu Nuo looked deeply at these ultrasonic detection devices.

Just like the previous super bomb, a normal grenade may not even be able to deal with two-star superhumans. However, the super bombs improved by the British Empire Research Department can cause certain damage to four-star legendary strongmen. If there are enough numbers, they can even kill four-star legendary strongmen directly!

The ultrasonic detection equipment in front of him really cannot detect his ultrasonic waves, but if the British Empire Research Department further researched similar extraordinary detection equipment, he might not be able to deceive him.

The combination of extraordinary power and modern technology is also a way to heaven!

However, Xu Nuo quickly restrained his mind. Combining extraordinary power and technology will indeed be a way to heaven, but it is not an easy task to understand this way.

No matter what matters, when it comes to R&D, it takes a lot of time to accumulate, and it cannot be successful overnight.

It's like a super bomb. It took at least thirty years to develop this thing!

When the research department studies the relevant ultrasonic detection equipment, it is not known that it is the year of the monkey and horse month.

No ultrasound was detected, Xu Nuo passed through the stalking location set up by the royal family and the four legendary families very smoothly, and no one found it in the middle.

I continued to move forward all the way, and I didn't encounter any problems in the middle.

Thinking about it, there are only two traces of Xu Nuo’s ultrasonic waves in the entire city of London. Xu Nuo deliberately narrowed his ultrasonic detection range to 500 meters.

Within such a large range, how could such a coincidence happen if you encounter these only two people?

Naturally, Xu Nuo returned to the Victor Castle smoothly.

After Alexander's death, most of the soldiers who had originally surrounded the entire Victor Manor were removed, and only a few people stayed here, barely playing a role in not letting people enter casually.

After all, the fact that this castle is not easy to release and let people see it is so difficult, so I can only block it for the time being and wait until the traces are processed in the future before making other arrangements.
