1375 Happy Cooperation

Princess Romanti stared at the door made of some special alloy under her feet. She no longer felt anxious and worried. Instead, she was more excited and looking forward to it.

She had never expected that the Morse code that Angie Prairie had taught her would be used in such a place because she had unintentionally mentioned it and felt that it was fun.

When she heard Chu Nan’s response from below, she almost jumped up in excitement.

Fortunately, her many years of training and experience allowed her to still try her best to remain calm in this situation and continue to use Morse code to communicate simply with Chu Nan.

Looking down at her feet, she was a little surprised to discover that she did not suspect Chu Nan at all.

Clearly, Chu Nan was currently fighting intensely with someone below. Moreover, the situation did not sound good, but Princess Romanti believed that Chu Nan could make the most correct response under such circumstances and find a way to escape.

“Follow my instructions later.”

If anyone else said this to Princess Romanti, she would definitely sneer.

The powerful strength and extraordinary knowledge created by many years of experience made Princess Romanti only have absolute confidence in herself. She had never truly trusted others.

However, when she heard the message sent by Chu Nan through the Morse code, Princess Romanti did not have any objections or disdain. She only felt that it was natural.

She had not thought so much just now. Now that she was squatting down and calmly waiting for Chu Nan’s further actions, as she had nothing else to do for the time being, she suddenly thought of this.

“When did I believe this guy so much?” Princess Romanti frowned slightly.

After thinking for a moment, she felt that this reason could only be attributed to Chu Nan’s special care for Viennelle and the powerful strength and maturity that he had displayed that far exceeded his age.

This guy… never seemed to do anything he was not confident in.

Just as she was recalling the various details she had known since Chu Nan first met, Princess Romanti suddenly felt abnormal spatial energy in the space below.

Looking down, he saw strands of black gas suddenly seeping out of the metal door, as if the door itself was emitting steam, but it was black.

Princess Romanti narrowed her eyes slightly, and her expression involuntarily carried a trace of surprise.

This color, this spatial energy fluctuation, and this method of affecting the surrounding environment were simply identical to the Exterminating Heart Technique!

Chu Nan released this?

Princess Romanti became wary.

She knew that Chu Nan knew part of the Exterminating Heart Technique. She had even personally explained it to him in order to save Viennelle.

However, the Exterminating Heart Technique she had taught Chu Nan at that time was only a very basic internal cultivation method. The ability to affect spatial energy displayed by the strands of black gas coming up from below had clearly exceeded the scope of what she had taught him previously.

“This guy is really a genius.”

Princess Romanti sighed in her mind and suppressed that trace of vigilance. Then, she stretched out a hand and placed it in the black gas. As she quietly experienced the spatial energy fluctuation in the black gas, she listened intently.

Thump! Thump! Thump! Thump!

As expected, intermittent weak knocks sounded from below. Although they were not very coherent, they could still barely analyze the meaning through the Morse code.

“Cooperate with me and use the Exterminating Heart Technique on this door at the same time.”

“Hmm?” Princess Romanti frowned again.

Use the Exterminating Heart Technique on this door? What did he mean?

However, she was only puzzled for a moment before knocking twice and giving Chu Nan a very simple answer.

“Okay.”

The black gas that surged up from under the metal door was also intermittent, proving that Chu Nan clearly could not continuously do what he wanted to do to the door. However, this did not stop Princess Romanti. She pressed her hands on the door and used one hand to sense the fluctuation of spatial energy in the black gas that Chu Nan passed through the door with all his might. Her other hand entered her Internal Breath and began to circulate the Exterminating Heart Technique.

As the most outstanding princess among the descendants of the royal family of the Declan Empire, Princess Romanti’s talent was unquestionable. She quickly understood the subtle difference between the strands of black gas emitted by Chu Nan and the normal Exterminating Heart Technique. After a moment of thought, she activated her Internal Breath and adjusted the spatial energy she controlled to nearly the same posture as the black gas Chu Nan released.

The black gas released from her palm intertwined with the black gas released by Chu Nan and rolled like two black clouds. However, soon, the black gas released by Chu Nan made the corresponding adjustments and Princess Romanti made some adjustments.

Soon, the two black gases were basically adjusted to the same posture. The spatial energy vibration was almost completely synchronized. Then, Chu Nan continued to adjust the black gas he released and Princess Romanti did not hesitate to cooperate.

Because Chu Nan was often interrupted, the steps of the two of them adjusting were not fast. However, after adjusting bit by bit, the spatial energy fluctuation in the black gas that represented the Exterminating Heart Technique gradually became stronger and the frequency of vibration became higher.

Thump! Thump! Thump! Thump! Thump!

Another soft sound sounded from below. Princess Romanti listened intently and understood what Chu Nan meant.

“I’ve adjusted it. Activate it at the same time as me.”

Princess Romanti immediately focused her attention on the door.

After a while, a loud bang sounded from below, as if something heavy had collided with the door. Then, there were a few soft knocks.

“Get ready.”

Princess Romanti immediately activated her Internal Breath and urged the Exterminating Heart Technique with all her might.

A moment later, the dense black gas deep under the door again quickly fused with the black gas released by Princess Romanti.

The two black gases fused into one and quickly enveloped the entire door, even spreading a portion of the passageway wall beside it.

Princess Romanti suddenly felt an extremely powerful vibration in the black gas coming from below. Without thinking, with a thought, the Exterminating Heart Technique circulated again, and the spatial energy around her entered the black gas.

Boom!

The metal door suddenly exploded into dust that filled the sky, revealing the deeper passageway below and Chu Nan’s slightly pale smile.

When his gaze collided with Princess Romanti’s surprised gaze, Chu Nan waved at her.

“Heh, Romanti, happy cooperation.”
