Mad Doctor No. 9

The plane took off and headed straight for western Sichuan.

On the way, the group carefully analyzed the existing intelligence and formulated a preliminary plan: first, establish a purification camp on the outskirts to treat the people who were affected by the Yin Sha.

Then, organize an elite team, carrying special protective equipment and purification artifacts, to delve into the Nine Nether Caves, investigate the root cause of the core anomaly, strengthen the seal as needed, eliminate hidden dangers, and destroy any potential forces of the Eternal Life Society.

Zhang Tianshi and Yu Xuzi were responsible for dealing with the Yin energy and potential spiritual threats; the military's strongmen were responsible for dealing with physical dangers, while the Eternal Life Society's armed personnel were responsible for combat; Wang Tian, ​​with his extremely Yang and powerful medical skills at his core, played a decisive role at the most critical moment.

A few hours later, the plane landed at a military airport in western Sichuan. The group transferred to a helicopter and soon arrived at the mountainous area where the Nine Netherworld Cave was located.

Nestled among distant mountains, there lies a colossal black hole, like the eye of a demon, constantly spewing forth dark gray mist.

For miles around, the air was bitterly cold, and even the sunlight seemed to dim.

Temporary isolation areas and medical tents stretched as far as the eye could see, with medical staff coming and going, yet the number of people falling into comas was increasing.

The situation is far more serious than we imagined.

The action team did not dare to slack off. Under the command of Zhang Tianshi, they began to set up a purification array and distributed talismans and protective artifacts to medical staff and those who had not yet evacuated, temporarily controlling the leakage of yin energy.

Wang Tian personally took action, using golden needles to puncture acupoints and the power of the stars to expel the Yin energy from the bodies of several unconscious people. However, this was only a temporary solution, as the root cause remained deep within the underground cave.

Wang Tian looked at Zhang Tianshi and the others and said, "We need to go in quickly."

Not long after, an elite reconnaissance team consisting of Wang Tian, ​​Zhang Tianshi, Yu Xuzi, Shan Yue, and Li Ren, carrying the necessary equipment and communication devices, stepped into the entrance of the Nine Nether Caves under the expectant yet apprehensive gazes of countless people.

The cave was pitch black, and the powerful flashlight could only illuminate a distance of about ten meters.

The air was thick and cold, filled with the smell of decay and sulfur, and an invisible spiritual pressure was eroding the spirit of the invaders.

The ground was covered in slippery stones and a sticky, indescribable substance.

"Stay close, watch your step, and watch the surrounding rock walls," Mountain, as the tactical commander, warned in a deep voice.

The two men, carrying specially made high-intensity spotlights and thermal detectors, led the way.

After walking another hundred meters or so, the passage began to slope downwards, and the temperature dropped accordingly.

On the stone walls on both sides, some ancient murals and runes are faintly visible, mostly depicting scenes of suppression, battle, and sacrifice, with a gloomy and terrifying style.

"These are... variants of ancient demon-suppressing talismans, but many of them are already dim and damaged." Zhang Tianshi examined them carefully and said, "It seems the legend is true; something extraordinary is sealed inside."

Suddenly, the lead blademan stopped and said in a deep voice, "Something's happened! There's a strong energy reaction ahead! And quite a lot of it!"

Just then, a rustling sound suddenly came from the darkness ahead, followed by a chilling sound of bones cracking.

The next moment, countless pairs of eerie green eyes lit up in the darkness!

"A Yin Corpse! An ancient corpse controlled by Yin energy!" Yu Xuzi drew his longsword, its blade gleaming with a clear light.

Dozens of ancient corpses, dressed in tattered clothes and withered bodies, yet moving with extraordinary agility, surged out of the darkness like a tide, rushing straight at the group! They had long black fingernails, spewed black smoke, and were fearless in the face of death.

Just then, a loud shout rang out: "Fire!" Without any hesitation, Mountain and Blade unleashed a barrage of specially made submachine guns. The bullets struck the corpses with dull thuds, forcing them back and even shattering some of them, but there were simply too many corpses.

"Summon lightning!" Zhang Tianshi chanted, and several purple talismans shot out, burning in mid-air into several arm-thick purple lightning bolts, which crashed into the pile of Yin corpses, instantly turning seven or eight Yin corpses into charred remains! The effect was very good, but the price was also very high.

Yu Xuzi's sword light was like a rainbow, and he moved with the sword. Each sword strike accurately severed the head of a Yin Corpse or pierced its heart. His swordsmanship was exquisite and his efficiency was extremely high.

Wang Tian didn't use any powerful moves. He simply pointed his fingers like a sword, and beams of starlight shot out from his fingertips, precisely striking the Yin Corpse's brow and chest.

The starlight is extremely yang, and has a natural restraining effect on the Yin Corpse. After being hit, the Yin Corpse immediately stiffens on the spot, and the Yin energy in its body is completely purified, causing it to collapse to the ground with a thud.

His movements were fluid and graceful, seemingly not very fast, but surprisingly efficient. Wherever he went, corpses fell in droves, while he was also able to spare some energy to observe his surroundings.

In just a few minutes, dozens of corpses were cleaned up.

The air was filled with a burnt smell.

"President Wang is amazing!" Zhang Tianshi exclaimed. "So amazing, so amazing." "You flatter me, Tianshi. Only the power of thunder magic can dispel evil," Wang Tian said politely, then frowned and said, "These Yin corpses are just small fry on the outskirts. Further in, there will definitely be stronger guards. Everyone, be careful and conserve your strength."

The deeper we went, the more we went.

The underground cave has a complex structure with many branching paths, but following the energy detection and the guidance of ancient runes, the path leads to the core area, where the yin energy is the strongest.

Along the way, they encountered several more powerful evil beings, including "evil spirits" formed from pure yin energy, giant corpse worms that could spew poison, and even some "enhanced yin corpses" that were clearly modified with modern technology, making them more agile and stronger in defense. It was obviously the work of the Eternal Life Society.

However, with the five of them working together, they managed to get through the challenge without any major incidents. They also obtained several "Yin Sha Crystal Cores" and fragments of Eternal Life Society standard equipment from the enhanced Yin Corpse.

The further they went, the stronger the spiritual erosion in the air became. If the five of them had not been so determined and had such profound cultivation, they would probably have lost their way long ago.

Along both sides of the passage, complete ancient sealing runes emerged, but most of them were dim and some were even broken.

Finally, the group passed through a huge stone door engraved with broken runes and arrived at an extremely spacious underground space.

This place is like a huge underground cave, hundreds of meters high and several miles in circumference.

In the very center of the cave stands a huge pyramid-shaped altar, built of an unknown type of black rock!

On the altar, a dark red, fleshy tumor the size of a human head writhed and emanated an aura of evil and resentment! Countless black chains, formed from yin energy, spread across the altar and wrapped around the tumor, but many of them were broken or had lost their luster.
