The Royal daughter of Romanti stared at the door made of special alloy. Her heart was no longer anxious and worried, but more excited and expected.

She never thought that the Morse code that Angela Belle gave her was actually used in such a place because she thought it was fun because Angela Belle accidentally mentioned it.

When hearing Chu Nan's response from below, she almost jumped up excitedly.

Fortunately, years of training and experience enabled her to keep calm as much as possible in this situation and continue to communicate with Chu Nan simply by using the Morse code.

Looking down at her feet, she was surprised to find that she didn't doubt Chu Nan at all.

Obviously, Chu Nan is now fighting fiercely with people here, and it doesn't sound very good, but the Royal daughter Romanti believes that Chu Nan can make the most correct response and find a way to get out of trouble.

"Follow my instructions later."

If someone else said this to the Royal daughter Romanti, she would scoff at it.

With the strong strength and extraordinary insight created by years of experience, the Royal daughter of Romanti will only have absolute confidence in herself, and she will never have real trust in others.

However, just now she heard the news delivered by Chunan through the sound of the moss code, but the Royal daughter of Romanti didn't have any idea of disgust and contempt in her heart, just took it for granted.

She hadn't thought so much just now. Now she squatted down and waited for Chu Nan's further action, but she suddenly thought of it because there was nothing else to do for the time being.

"When did I trust this guy so much?" The Royal daughter of Romanti frowned slightly and raised two eyebrows that were slightly stiff for girls.

After thinking about it, she thought that this reason could only be attributed to the fact that Chunan had taken care of vianne Nair before, and the strong strength and maturity far beyond his age during the period of contact with Chunan.

This guy... Doesn't seem to do anything uncertain.

While recalling various detailed pictures from Chu Nan's first meeting to the present, the Royal daughter of Romanti suddenly sensed the change of spatial energy in the space below.

When I saw the black steam coming out of the gate, I looked as if it was black.

Romanti's eyes narrowed slightly, and a trace of consternation hung involuntarily in her expression.

Such color, such as like as two peas, the energy fluctuation of space, and the way of influencing the surrounding environment are just like those of the vanishing heart.

Is this released by Chu Nan?

There was a trace of vigilance in the heart of the Royal daughter Romanti.

Chu Nan knows some devoid mental skills. She knows them. Even these devoid mental skills were explained to Chu Nan by herself in order to save vianne Nair at that time.

However, the vanishing mind method she taught Chu Nan at that time was only a very primary mind method, and now the influence ability on space energy reflected in the plume of black gas from below has obviously exceeded the scope she taught Chu Nan before.

"This guy is really a genius."

The Royal daughter of Romanti sighed in her heart, pressed down that trace of vigilance, then stretched out a hand and put it into the black gas. While quietly experiencing the spatial energy fluctuation in the black gas, she listened attentively.

"Bang Bang Bang Bang..."

Sure enough, there was an intermittent weak knocking sound below. Although it was not very coherent, it was still able to reluctantly analyze the meaning through the Morse code.

"Cooperate with me and use the devoid mind method on this door at the same time."

"Huh?" Princess Romanti frowned again.

Use the devoid mind method on this door? what do you mean?

However, she just wondered for a moment, then knocked on the door twice and gave Chu Nan a very simple response.

"OK."

The black gas pouring up from under the metal door was also intermittent, which proved that Chu Nan obviously couldn't continue to do what he wanted to do to the door, but it didn't hinder Royal daughter Romanti. She pressed her hands on the door, with one hand fully aware of the fluctuation of space energy in the black gas that Chu Nan came up through the door, and the other hand adjusted into the breath and began to run the vanishing mind method.

As the most outstanding Royal daughter of the generation of royal children of the imperial family of the dikelan Empire, there is no doubt about the talent of Royal daughter Romanti. She soon figured out the subtle difference between the continuous black Qi emitted by Chu Nan and the normal vanishing mind method. After a little consideration, she has activated internal breathing and adjusted the space energy under her control to be close to the same posture as that emitted by Chu Nan.

The black gas emitted from her palm was intertwined with the black gas emitted by Chu Nan, rolling like two black clouds, but soon the black gas emitted by Chu Nan made corresponding adjustments, and the Royal daughter Romanti also made some adjustments.

Soon, the two black gases were basically adjusted to exactly the same posture, and the spatial energy vibration was close to complete synchronization. Then Chu Nan continued to adjust the black gas he released, and the Royal daughter Romanti did not hesitate to make the adjustment.

Because Chu Nan is often interrupted, the adjustment steps of the two people are not fast. However, with a little adjustment, the fluctuation of space energy in the black Qi launched by the devoid mind method gradually intensifies, and the vibration frequency also becomes higher.

"Knock Knock Knock Knock Knock Knock Knock Knock Knock Knock Knock Knock Knock Knock Knock..."

There was another light noise below. The Royal daughter Romanti listened attentively and understood Chu Nan's meaning.

"It's adjusted. Start it together with me."

The Royal daughter of Romanti immediately improved her spirit and completely focused on the gate.

After a while, there was a loud "bang" below, as if some heavy object had hit the gate, and then there were several slight knocks.

"Ready."

Royal daughter Romanti immediately launched internal breathing and tried her best to urge the vanishing mind method.

A moment later, the strong black gas under the gate was again integrated with the black gas released by the Royal daughter Romanti.

The two black gases were combined into one, which quickly covered the whole gate, and spread part of the past together with the adjacent passage wall.

The Royal daughter of Romanti suddenly felt a strong vibration from the black Qi coming from below. She didn't think about it. Her heart moved, lost her mind method and turned around again. The energy of the whole body space entered and merged into the black Qi.

"Boom -"

The metal gate suddenly burst into pieces, showing a deeper passage below and a slightly pale smiling face of Chu Nan below.

They collided with the surprised eyes of Romanti's Royal daughter, and Chu Nan raised his hand to greet her.

"Hey, Romandy, have a nice cooperation."
