The Invincible Mercenary King (by Matt Watt) novel Chapter 689

Chapter 689 

Haylans explanation, Dr. Steinberg and the other doctor looked at each other in astonishment. 

entilation syndrome was indeed a rare condition in internal medicine. They had never encountered it in the clinical nce As such, it was reasonable that they did not know much about it. 

ceing the patient’s breathing normalize, the flight attendants and the air marshall heaved a sigh of relief. 

Along as the patient was fine, that was all that mattered. 

Alright, the patient is fine now. You guys may take over from here 

Haylan felt relieved after seeing the patient’s breathing stabilize. He pressed a few acupoints on the patient’s body and transmitted a strand of vital energy to him. After stabilizing the condition of his lungs, he immediately turned around and deft. 

After he left, Dr. Steinberg immediately took over and pressed the bag. 

Haylan turned around and said to Dr. Steinberg. “The patient’s breathing has stabilized. When his emotions calm down, and his breathing is back to normal, there’s no need to put on the bag anymore.” 

After saying that, he waved his hand and left without looking back. 

Upon hearing those words, Dr. Steinberg’s expression slightly changed. He quickly loosened his grip on the bag, afraid of holding it too tightly. He appeared somewhat apprehensive and nervous. 

Haylan looked calm when he returned to his seat. 

At this moment, Reign was still gazing out the window. When she saw Haylan return, she heaved a sigh of relief and resumed observing the scenery outside. 

“How is it? What disease?” Yvonne asked curiously. 

“It’s just hyperventilation syndrome, not a big deal,” Haylan said indifferently. 

“Hyperventilation syndrome? What disease is that?” Yvonne looked puzzled. 

“In layman’s terms, it’s exhaling too much air,” Haylan said. 

“Exhaling too much air can cause disease too?” Yvonne was even more puzzled. 

“Not only can it cause disease, but it can also be life–threatening if it’s not handled properly.” Haylan said. 

“Damn it, such a thing can be life–threatening too? Will I get it when I pant during my usual exercise?” 

That won’t happen.” 

“That’s good” 

Hearing this, Yvonne heaved a sigh of relief. 

At this moment, Haylan spoke again. “However, intense exercise might cause pneumothorax, and if pneumothorax aggravates, it can be life–threatening.” 

“You…” 

Hearing what he said, Yvonne glared at Haylan on the spot. “Will you die if you don’t scare me?” 

Following that, she pulled Reign’s hand and said coquettishly, “Rei, take care of this departmental head of the security department. He’s scaring me.” 

Reign turned around and said, “Can you guys stop making noise? I’m a little tired now and want to rest. 

When Yvonne heard this, she could only stick out her tongue and stop talking 

Secing Reign’s worried expression, she had initially thought of cracking a joke to cheer her up. 

She did not expect Reign to be so heavy–hearted that she did not want to joke. 

“I’ll sleep for a while. You guys don’t disturb me.” 

Reign was gloomy with worry. She ignored Haylan and Yvonne and closed her eyes tightly to sleep after lowering the seat. 

It took 12 hours to travel from Longhard Kingdom to Whileal Kingdom, even if taking a flight. 

Now, all she wanted was to sleep well and recharge her energy. By the time she landed, she would have the strength to take oh all the tasks. 

Seeing Reign’s weary and worried expression, Haylan’s heart ached. 

Reign was just a woman but had to take on so much. Now, she most probably has to face her younger brother’s demise. ħ
