Immortal Doctor Expert in Urban

The palms of two Hidden Kill experts struck Lin Fei's dantian.

A bizarre scene unfolded. After the two Hidden Kill experts' palms hit Lin Fei's dantian, not only did Lin Fei not cry out in pain, but instead, the two experts screamed continuously: "Ahhh!~~~"

With their screams, their bodies convulsed continuously, as if electrocuted.

They indeed felt as if electrocuted. When their palms struck Lin Fei's dantian, a terrifying force suddenly appeared, capturing their palms.

Under this terrifying force, their entire bodies couldn't help but convulse.

After the force from their bodies was completely drained by the terrifying power at Lin Fei's dantian, they collapsed to the ground as if exhausted, falling unconscious.

This left Yue Ling and the three old masters dumbfounded. What was going on?

The dantian is considered the most crucial part for martial artists. If the dantian is attacked, it can be devastating, ruining martial arts or severely injuring primordial qi.

The two Hidden Kill experts clearly struck at Lin Fei's dantian, and both had the strength of masters. If they attacked Yue Ling in such a way, even he, with the strength of the Ninth Layer Grandmaster, might have his skills ruined.

Yet, not only was Lin Fei's martial arts not destroyed, but the two Hidden Kill experts also fell to the ground.

This was beyond baffling!

Yue Ling suddenly thought that Lin Fei must have used some technique to trick the two Hidden Kill experts.

Clink, the sound of chains falling to the ground was heard. The chains binding Lin Fei were shaken off by Lin Fei and fell to the ground.

Seeing this, the three old masters showed joy in their eyes, realizing that Lin Fei had not lost his martial arts.

Anger gathered in Yue Ling's eyes as he said to Lin Fei, "It seems you don't want your martial arts destroyed. In that case, I will kill this old man now."

"Wait, Squad Leader Yue, that's not correct!" Lin Fei said to Yue Ling, "You want to ruin my martial arts, which I also agree to. They suddenly collapsed to the ground, but isn't that unrelated to me?"

Yue Ling recalled his two subordinates convulsing and secretly thought: Could it really be an accident?

However, Yue Ling quickly dismissed this idea, saying coldly to Lin Fei, "Lin Fei, don't think I'll believe what you say."

"Since you are unwilling to have your martial arts destroyed, I will kill this old man!"

As soon as he said this, Yue Ling's short knife suddenly sliced towards Qin Chuan's neck.

Whoosh!——

Before it could make contact, a silver needle shot out like a meteor.

It hit unerringly on the back of Yue Ling's hand holding the short knife. The silver needle pierced deep, causing him to cry out in pain: "Ah!~~~"

Pained and numb, Yue Ling's hand opened up, and the short knife fell down.

At the same time, Lin Fei, who had shot the silver needle, had a sharp gleam in his eyes. In the next moment, Lin Fei was already in front of Qin Chuan, grabbing the falling short knife.

"Grandpa Qin, duck your head!" Lin Fei shouted to Qin Chuan.

Qin Chuan immediately lowered his head, allowing Lin Fei to see Yue Ling drawing another short knife from his back and stabbing toward Qin Chuan's lower back.

At this critical moment, Master Yuan and Master Xiao saw the flash of Lin Fei's knife light.

It was like lightning breaking through clouds, emitting a blinding radiance.

The two masters felt a suffocating killing intent sweeping out!

Swish!

As Lin Fei's knife light passed, Yue Ling's eyes opened wide, filled with extreme fear and deep suspicion.

Immediately, with a thud, Yue Ling fell straight backward. A line of blood suddenly appeared on his neck, growing thicker and thicker until blood spurted out, covering the ground.

Yue Ling died with his eyes wide open, seemingly unable to believe he would die to Lin Fei's throat-slitting strike.

In the glow of the fire, Lin Fei's short knife remained sharp and clean, as if it hadn't killed anyone.

Yet, Master Yuan and Master Xiao knew in their hearts that the reason no blood was seen on Lin Fei's short knife was his attack speed was too fast.

As Lin Fei's knife sliced through Yue Ling's throat, no blood was left, and the deep blood line appeared with the spurting blood only after Yue Ling fell.

Master Yuan and Master Xiao's minds were unsettled for a long time; this was perhaps the fastest knife they had seen in their lives!

Shua.

At this moment, Lin Fei's short knife, like a flash of lightning, severed the chains on the hands of the three old masters.

Amidst the sparks, all the chains on the three old masters were severed.

"Grandpa Qin, Grandpa Yuan, Grandpa Xiao, are you all right?" Lin Fei asked the three old masters with concern.

The three old masters finally came back to their senses and hurriedly said to Lin Fei, "Lin Fei, we're fine!"

If it weren't for Lin Fei, they might have already died.

Lin Fei could also see that the three old masters, though wounded, only had flesh wounds, not threatening their lives.

"Three masters, let's leave now!" Lin Fei said to the three old masters.

The three looked at Yue Ling lying dead on the ground, then at the two unconscious Hidden Kill experts, and nodded at Lin Fei.

Then, the three masters followed Lin Fei out of the cave.

Under the dim moonlight, the four began their descent.

On the way down, Lin Fei asked the three old masters, "How did Hidden Kill know you knew about my grandfather's whereabouts?"

Hatred flared in Qin Chuan's eyes as he said, "It was all because of Huadu Medicine King Dong Qingshan. He told Hidden Kill that we knew the whereabouts of Medical Saint Lin."

"After we return, we must find Dong Qingshan and take revenge."

Lin Fei said to the indignant old masters, "Masters, Dong Qingshan is already dead."

"Dead?" the three old masters exclaimed in surprise.

Lin Fei nodded, "Yes, Dong Qingshan was killed by Yue Ling."

The three old masters clapped in approval, "Serves him right!"

"Masters, do you know why Hidden Kill is looking for my grandfather?" Lin Fei asked the three old masters.

The three old masters exchanged glances, then looked back at Lin Fei, and said, "Lin Fei, didn't your grandfather tell you?"

Lin Fei looked bewildered, "Tell me what?"

Qin Chuan said, "Martial Saint Heart Sutra."

"What is that?" Lin Fei couldn't help but ask in confusion.

"It's a martial arts secret, the essence of the life-long martial skills of the ancient Martial Saint Lin Qingyu, revered for centuries by martial artists as the Martial Arts Holy Scripture. Whosoever obtains the 'Martial Saint Heart Sutra' can become a Martial Saint, not only becoming number one in the world but also able to pursue the path of longevity, living several hundred years without dying, becoming a legend of immortals."

Lin Fei was stunned: Could there really be such miraculous martial arts in the world?

Qin Chuan continued, "Sometime ago, it was rumored in Huaxia that Medical Saint Lin obtained the 'Martial Saint Heart Sutra' of the ancient Martial Saint Lin Qingyu. Though Medical Saint Lin repeatedly denied it, many martial arts experts continue to pursue him."

"To stay away from trouble, Medical Saint Lin has been secluded in Kunlun for many years, yet now, trouble arises again."

Lin Fei frowned slightly, "So, this time, Hidden Kill came for my grandfather's 'Martial Saint Heart Sutra'?"

Qin Chuan nodded, "Indeed."
