Chunan almost thought he had developed auditory hallucinations under the strong pressure of Dr. quelsaros and director Romon.

The noise was very slight, but it was obviously the sound of regular knocking on the metal door behind you.

It sounds... Like someone is knocking at the door!

"What the hell..."

Chunan shook his head gently, raised his hand and took another blow from Dr. quelsaros, and hit the door again.

This time, he didn't fly in a hurry. Instead, he leaned close to the door, measured his head and put his ears on the door. It looked like he was overwhelmed and wanted to have a rest close to the door. In fact, he was concentrating on listening to the sound from the other side of the door.

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

After listening, Chu Nan immediately determined that the percussion sound was definitely deliberately knocked out, because these percussion sounds have a special rhythm. Of course, people who don't know can't understand it. Chu Nan was a little confused at the beginning, but after thinking about it, he immediately understood it.

This knock is actually in the way of Morse code!

Once you want to understand this, you can contact the paragraph just now. After being translated through the Morse code, it actually represents a very short sentence.

"Chu Nan, are you in there?"

"Boom -"

At the same time, Chunan reluctantly dodged away from the slap that director Romon secretly hid under Dr. quelsaros, forced them back, and flew back to the door. His left hand pressed on the door, but his right hand was behind him, bent his fingers and knocked.

"Bang -- Bang -- Bang..."

Of course, Dr. quelsaros and director Romon won't give Chu Nan much comfortable time. Chu Nan's percussion was also carried out by means of moss code. It didn't last long, and only one sentence could be delivered reluctantly and completely.

"I'm Chu Nan. Who are you?"

The last two strokes were knocked out by Chunan forcibly staring at the attack of Dr. quelsaros and director Romon, which made him pay a painful price. He was slapped by director Romon, resulting in serious internal injuries and a mouthful of blood gushing out.

Fortunately, he had calculated this situation before deciding to do so. He not only operated the fire skill of life in advance, but also simultaneously launched the hymn skill of the goddess to minimize the damage caused by this blow to himself, and it took only two blinks to recover. Then he did not hesitate to adjust his internal breathing to seven turns, condense the energy of the whole body space and blow it away.

At this time, Dr. queer didn't laugh hard. Instead, he didn't laugh hard again.

"Ha ha, boy, that's right. Fight me like a man!"

"Boom -"

Chunan's fist accurately collided with Dr. quelsaros's fist. A terrible force surged out of the two people's fists, and the huge energy impact shattered the space inside the whole channel.

Dr. quelsaros's huge body was shocked by the powerful impact contained in Chunan's fist and flew backward at a high speed below the channel, together with director Romon, who didn't expect him to be hit and caught off guard for a while.

Chu Nan was also hit and flew. His body soared up and hit the door again.

"Bang -"

After the loud muffled noise, Chu Nan heard another faint knock from behind the door.

"Bang Bang..."

Chu Nan listened attentively and soon got the meaning of this sentence by confirming the Morse code.

"I'm Romanti, Chunan. Are you okay?"

Chu Nan was stunned.

It's Romanti's daughter.

When judging that the knocking sound is in the way of Morse code, Chu Nan's first thought is Angie Belle, because it is obvious that only those who also come from the Earth Federation will understand the Morse code. Besides Angie Belle, how can another person from the Earth Federation suddenly appear here.

But now... Judging from the response, it was the Royal daughter of Romanti, which was beyond Chu Nan's expectation.

"I'm fine. Why did you get down?"

Chunan only had time to type out such a short sentence. Dr. quelsaros and director Romon had killed again.

Just now, Chunan gathered seven turns of internal breathing and mixed almost all the space energy in his body. Dr. quel Saros was more alert to Chunan, and the attack was not as compact as before, and the same move of director Romon became more cautious.

Although this makes their attack more troublesome for Chu Nan, it also gives Chu Nan more "free" time than just now.

Chu Nan put on a posture of being unable to get rid of the blockade. His back was tightly close to the metal gate. While he looked very embarrassed to respond to the attack of the two people, he took time to knock on the gate behind him from time to time and had a short communication with the Royal daughter of Romanti outside the door.

"How do we get in when we hear the sound coming down?" Princess Romanti asked again.

"Only this door. Cooperate with me."

"How to cooperate?"

"Follow my instructions later."

Time was pressing, and naturally there was no way to have a detailed talk with the Royal daughter of Romanti. Chu Nan explained to the Royal daughter of Romanti in a few words, then took a deep breath, condensed his internal breathing, adjusted it to seven turns again, matched with the space energy swarming out, and his body shape moved. He would pass the attack of Dr. quelsaros and hit somewhere in the middle and lower part of his huge body.

Based on the feedback data obtained from his previous attacks, it can be inferred that this part should be the weaker part of Dr. quelsaros's huge body transformed into the third form.

In fact, as he predicted, Dr. quelsaros obviously didn't expect that Chu Nan had resisted them with his back against the metal door for a long time. Now he suddenly flashed and found a gap in his extremely narrow space and hit the punch with great accuracy.

After being hit by a punch, Dr. quelsaros's huge body shook violently, and a mouthful of unknown liquid mixed with red, green and black ejected from the position of his head. The position hit by Chunan's punch also sank down. It was probably made of muscle tissue, and things like armor fell off one after another, revealing the tender red and new growing skin inside.

With the help of this fist, Dr. queirnan could not help but draw back. He was also very cautious.

While both of them retreated, Chu Nan clapped his backhand on the metal door behind him, and a black gas seeped out of his palm.
