The time humans can endure asphyxiation before dying is four to six minutes, but for the majority, there aren’t significant issues within four minutes. A few can endure up to six minutes.

However, for an untrained person, asphyxiation beyond six minutes will lead to irreversible brain damage due to lack of oxygen.

The asphyxiation mentioned here doesn’t include holding one’s breath, which typically doesn’t equate to oxygen deprivation. Holding your breath involves storing enough oxygen in the lungs to supply the body’s needs.

It requires strong lung capacity to support it.

Generally, an untrained person can hold their breath for about a minute, with two to three minutes being common, and even four minutes. Trained individuals can hold their breath for over ten minutes, even reaching 20 minutes.

Wang Feng’s nose and mouth were taped, causing forced asphyxiation for about three to four minutes.

After being rescued by Lu Chuan and Yang Lin, Wang Feng felt dizzy, and his vision blurred, but it didn’t cause irreversible damage.

"How did you find this place?"

Wang Feng struggled to sit up; the feeling of surviving the ordeal wasn’t as pleasant and beautiful as imagined.

When Wang Feng’s nose and mouth were taped, and he couldn’t breathe, a lifetime of memories seemed to flash quickly before his eyes just before he passed out.

Parents, relatives, classmates, first love...

Then his entire being sunk uncontrollably into darkness, deeper and deeper, as if in a bottomless abyss, struggling desperately but finding no way out.

Everything ceased to exist with the blackout before his eyes.

Upon waking, he saw the faces of Lu Chuan and Yang Lin.

"We found this building based on the surveillance video when you and Wu Lei left Huijia Garden District three days ago, in that vehicle."

Yang Lin quickly explained the process, and Wang Feng took a deep breath.

Leaning against the chair back: "Brothers, believe me, cherish the freedom of breathing air, each breath is a gift from heaven."

"Stop being sentimental, kid. What about these two people?"

The two people lying on the ground include Wu Lei, who took Wang Feng, and another bald man whose identity is unknown.

Wang Feng’s eyes fell on the unconscious two on the ground and looked at Lu Chuan: "Old Lu, you’re impressive now, when did you learn this skill?"

The two lying on the ground, Wu Lei was a small follower with no combat skills, but the bald guy was different.

This bald guy was a bodyguard for the Number 4 figure, not in Haizhou City, but hired from abroad by Number 4, who used to be a mercenary.

Wang Feng had seen him in action, extremely ruthless, with incredible strength, speed, and precision, yet he couldn’t last a single move against Lu Chuan.

Lu Chuan waved it off: "It’s just average, I occasionally practice a couple of moves at the Criminal Investigation Team, dealing with these small fries isn’t more than a move."

Lu Chuan spoke disdainfully, glancing casually at the two on the ground, seizing the chance to show off in front of his roommates.

At this moment, Zhang Hui came over to check on the two, Wu Lei showed no signs of waking, but the bald man was struggling to regain consciousness.

"Wang Feng, let me introduce you, this is Zhang Hui from our Criminal Investigation Team, Brother Hui led the team to find you this time."

Wang Feng had heard Lu Chuan mention Zhang Hui during their past meals together, but never met him before.

"Hello Brother Hui, I’ve always heard Lu Chuan mention you, having the chance to meet now, and causing you trouble for my matter."

"Nonsense, with you executing such dangerous tasks, this little we’ve done is only right."

Zhang Hui actually admired Wang Feng greatly.

Just graduated, yet went undercover, that’s no ordinary feat.

Especially since Wang Feng, having undergone systematic education and graduated from Public Security University, had habits that clashed with those of the criminal elements.

But going undercover required assimilation with the enemy, meaning words, actions, and one’s worldview conflicted with the norm.

Every word needed careful weighing, every action pondered and studied.

Plus, sometimes forced to do uncharacteristic things, taxing psychologically.

The bigger resistance came from family, as undercover work couldn’t be disclosed to them, for their protection, and to portray the undercover role more realistically.

Facing misunderstandings from family and relatives, the pressure was unimaginable.

"Old Wang, why did they want to kill you, is your identity exposed?"

Clearly, Wu Lei and the bald man wanted Wang Feng dead, they wouldn’t kill without reason, dealing with Wang Feng likely meant his identity was exposed.

Wang Feng nodded, then shook his head: "I’ve always been a cop, just got dismissed, which they knew for a long time."

"My contact with the higher-ups was one-way only, very cautious, they shouldn’t have found out."

"They targeted me this time because Wu Lei felt I threatened his position."

"In Number 4’s circle, while Wu Lei wasn’t of significance, he was trusted, not involved in business, but looked after Number 4’s comforts."

"Last week, I captured a video of him having an affair with one of Number 4’s mistresses, planned to use it to negotiate with him, but didn’t expect the bastard to act out in desperation, wanting to kill me."

"And what about the bald guy?"

"Baldy is Number 4’s bodyguard, hired from a security firm abroad, in cahoots with Wu Lei, he also slept with Number 4’s old mistress."

"Both feared exposure of their deeds, so they conspired to kill me."

Just because of this?

Yang Lin and Lu Chuan felt Wang Feng’s situation was unfair.

Undercover work was going smoothly, but got exposed over such matters, it wasn’t worth it.

"What’s your plan now?"

"Can you continue with the undercover work?"

Zhang Hui pointed at the two on the ground, who certainly couldn’t be released, needing to be arrested, indicating Wang Feng’s real identity could be exposed to Number 4.

Meaning Wang Feng’s undercover operation was a failure.

"I definitely can’t continue undercover, but I recorded videos of these two torturing me over the days, and they thought they had me figured out, so they revealed much about Number 4."

As Wang Feng spoke, he removed a shoe, revealing a small recording device from behind his right heel.

In fact, after taking Wang Feng from Huijia Garden District three days prior, the two had intended to kill him that night.

However, they never acquired the videos Wang Feng took of them and Number 4’s women in the affairs. 𝘧𝓇ℯℯ𝑤ℯ𝘣𝓃ℴ𝓋𝑒𝑙.𝑐𝘰𝑚

Wang Feng threatened that should he be killed, those videos would be sent to Number 4’s phone, thus the two hesitated to act immediately.

Knowing, as confidents, just what kind of person Number 4 was all too well.

If his affairs with Number 4’s old mistress were to be uncovered, even retaining an intact corpse would be fortunate.
