I only reached the Foundation Establishment stage at eighty years old, and then the system appeared.

Under the protection of his master Tianlang and the five Immortal Emperors, Yang Huizhou honed his combat skills by fighting against all the demonic beasts that appeared in the training map. As long as his life was not in danger, even if he was covered in wounds, Tianlang and the five Immortal Emperors would not make a move.

However, the healing pills he carried were indeed very powerful; no matter what kind of injury he suffered, as long as he didn't die, he could recover after taking them.

This was given to him by the ancestor, who said it was personally refined by Madam Dongfang (actually, it was bought from the system, one point per bottle, ten pills per bottle).

On this day, the group entered a canyon (the author said this kind of place is full of treasures). The high mountains on both sides of the canyon blocked the sunlight, making the canyon seem gloomy.

As the group entered the canyon, a chilling aura swept over them, as if countless eyes were watching them from the shadows. Yang Huizhou gripped his immortal sword tightly, cautiously scanning his surroundings.

"The yin energy in this canyon is so heavy, there must be many powerful demonic beasts here," said a guard at the Immortal Emperor realm. His voice was deep and steady, giving people a sense of reliability.

Sirius nodded and said, "That's right, everyone be careful. Huizhou, you should also be prepared; a monster might come out to attack us anytime soon."

Yang Huizhou took a deep breath and said, "Master Tianlang, rest assured, I am ready."

No sooner had he finished speaking than a lithe shadow leopard darted out of the bushes beside him. It was incredibly fast, like a black lightning bolt, and pounced on Yang Huizhou.

Yang Huizhou reacted quickly, dodging the shadow leopard's attack with a sidestep, then swung his immortal sword at the leopard. The shadow leopard nimbly dodged, then pounced on Yang Huizhou again, and the two instantly engaged in a fierce battle.

"Huizhou, don't just use brute force. Think about the characteristics of the fox clan's techniques and use skillful techniques to deal with it," Tianlang reminded him from the side.

Upon hearing Tianlang's words, Yang Huizhou's heart stirred. He activated the fox clan's techniques, making his body even lighter and more agile, like a cunning fox. He skillfully dodged the shadow leopard's attacks while searching for an opportunity to counterattack.

Suddenly, seizing the opportunity, he darted behind the Shadow Leopard and thrust his immortal sword fiercely into its hind leg. The Shadow Leopard cried out in pain and turned to flee. Yang Huizhou, however, wouldn't let it go, chasing after it and striking again with his sword, killing the Shadow Leopard instantly.

"Not bad, Huizhou, you used that trick very cleverly," Tianlang praised.

Yang Huizhou wiped the sweat from his forehead and said, "Thanks to Master Tianlang's reminder, otherwise I really wouldn't have been able to deal with it."

They continued onward, and before long, they encountered another swarm of poisonous bees. These bees were enormous, their stingers gleaming with an eerie green light, clearly indicating their potent venom. They buzzed as they swarmed towards the group.

"Huizhou, we're counting on you this time. Although these poisonous bees are numerous, they are not strong individually, which is perfect for honing your group combat skills," said a Celestial Emperor.

Yang Huizhou nodded and said, "Don't worry, seniors, I won't let you down."

He channeled his immortal power, forming a protective shield around his body, then, wielding his immortal sword, charged into the swarm of poisonous bees. He brandished his sword, unleashing a crisscrossing array of sword energy that slashed down the surrounding bees. However, the number of bees was overwhelming, swarming in from all directions, and Yang Huizhou gradually found himself struggling to keep up.

"Huizhou, don't just focus on hacking and slashing, try attacking them with immortal techniques," Tianlang shouted from the side.

Upon hearing this, Yang Huizhou immediately used his magic, unleashing streams of flame from his hands towards the swarm of poisonous bees. The bees sizzled and scattered as they were burned by the flames. However, many bees disregarded the danger and continued to charge towards Yang Huizhou.

Yang Huizhou unleashed another ice-based immortal technique, freezing the surrounding space and trapping many poisonous bees inside, unable to move. He then seized the opportunity to swing his immortal sword again, annihilating the remaining poisonous bees.

"Phew, finally solved." Yang Huizhou breathed a sigh of relief and said, "These poisonous bees were really hard to deal with."

"You did very well, Huizhou. In the face of group battles, you must make flexible use of various immortal techniques and skills to achieve victory," Tianlang said.

They continued deeper into the canyon, encountering numerous attacks from demonic beasts along the way, but Yang Huizhou repelled them all. With each battle, Yang Huizhou learned something new, his combat experience grew richer, and his strength steadily increased.

On this day, they arrived at a cave. The cave was filled with a mysterious aura and still had a powerful pressure, as if a peerless expert had once lived here.

"There might be some treasure in this cave, Huizhou, why don't you go in and take a look?" Tianlang said.

Looking at the cave, Yang Huizhou hesitated for a moment and said, "Master Tianlang, the pressure in this cave is so strong, isn't there any danger?"

Sirius said, "There will definitely be dangers, but this is also a good opportunity to train you. Don't worry, we'll be watching outside, and we'll come to your rescue if you're in any danger."

The five Celestial Emperors also said, "Young Master, please go in with peace of mind. We will protect your safety."

Yang Huizhou thought for a moment, nodded, and said, "Okay, then I'll go in and take a look."

He cautiously entered the cave. The cave was dimly lit and filled with a pungent odor. Yang Huizhou channeled his immortal power, conjuring a ball of light in his hand to illuminate the surroundings.

He slowly made his way through the cave passage when suddenly, a huge stone monster emerged from the wall beside him. The monster was enormous, its body made entirely of hard stone, and it swung its massive arms at Yang Huizhou.

Yang Huizhou dodged the stone monster's attack by sidestepping, then swung his immortal sword at it. However, the sword struck the stone monster, only sending up a shower of sparks, and did not cause it much damage.

"This stone monster's body is so hard that ordinary attacks are useless against it. I need to think of another way," Yang Huizhou thought to himself.

He carefully observed the stone monster's movements and noticed that it was somewhat sluggish. So, using his agility, he quickly circled the stone monster, searching for its weakness. Suddenly, he discovered a crack in the stone monster's ankle, seemingly a vulnerable spot.

Seizing the opportunity, Yang Huizhou dashed to the stone monster's feet and thrust his immortal sword fiercely into the crack. The stone monster roared in pain, trying to stomp on Yang Huizhou, but Yang Huizhou nimbly dodged. He continued his attack on the crack, and soon the stone monster's ankle was severed, its massive body crashing to the ground.

Yang Huizhou breathed a sigh of relief and continued deeper into the cave. He hadn't gone far when he encountered another group of ghosts. These ghosts were elusive and exuded a sinister aura. They circled around Yang Huizhou, occasionally emitting sharp cries that disturbed his concentration.

"Hmph, you think you can stop me?" Yang Huizhou sneered, circulating his immortal power to form a golden shield around his body, blocking the ghost's attacks. Then, he unleashed his immortal magic, and bolts of lightning fell from the sky, striking the ghost.

The ghosts were struck by lightning, letting out screams as their bodies gradually became transparent. Taking advantage of this opportunity, Yang Huizhou used his magic again to destroy all the remaining ghosts.

After a grueling battle, Yang Huizhou finally reached the end of the cave. At the end of the cave, he discovered an object shaped like a winter melon. This object emitted a soft light, and its surface had strange patterns, as if it contained boundless power.

"What is this?" Yang Huizhou asked curiously as he approached, wanting to take a closer look.

Just then, the melon-shaped object suddenly emitted a bright light, enveloping Yang Huizhou. Yang Huizhou felt a powerful force surge into his body, and his body began to tremble uncontrollably.

"Ah!" Yang Huizhou cried out in pain. He tried to struggle, but he couldn't move.

Upon hearing Yang Huizhou's cry, Tianlang and the five Immortal Emperors who were guarding outside tensed up. Tianlang said, "This is bad, Huizhou might be in danger. Let's go in and check on him quickly."

They rushed into the cave and reached its end. Seeing Yang Huizhou enveloped in light, Tianlang said, "Don't panic, everyone. This might be Huizhou's opportunity. We'll protect him and wait for him to absorb this power."

Everyone nodded and quietly stood guard beside Yang Huizhou. After a while, the light gradually dimmed, and Yang Huizhou's body stopped trembling. He slowly opened his eyes, which gleamed with excitement.

"Master Tianlang, seniors, I feel that my strength has improved a lot," Yang Huizhou said.

Sirius laughed and said, "It seems this melon-shaped object is a treasure, bringing you quite a stroke of luck. How are you feeling now?"

Yang Huizhou stretched his body and said, "I feel full of power, and my understanding of immortal techniques and cultivation methods has become much deeper."

The five Immortal Emperors also offered their congratulations: "Congratulations, young master, on obtaining such an opportunity, which has greatly increased your strength."

Sirius said, "Alright, now that Huizhou is safe and has gained an opportunity, let's leave this canyon. It's fraught with danger, and we shouldn't linger."

Everyone nodded and left the cave together, flying towards the edge of the canyon. On their way out of the canyon, they encountered some more attacks from demonic beasts, but Yang Huizhou easily repelled them all. His strength was now vastly different from before, and he seemed to handle these demonic beasts with ease.

After a period of flight, they finally left the canyon. Looking back at the canyon, Yang Huizhou was filled with emotion. This experience had helped him grow considerably and made him understand the cruelty and opportunities that coexist in the Immortal Realm. He knew that the road ahead was long, and he needed to continuously strive in his cultivation to gain a foothold in this Immortal Realm.

"Master Tianlang, seniors, this experience has been very rewarding. I've decided to continue training to improve my strength," Yang Huizhou said firmly.

Sirius nodded and said, "Good, it's good that you have this determination. However, you must remember that safety comes first. Don't fight back if you encounter danger; ask us for help immediately."

The five Celestial Emperors also said, "Young Master, rest assured, we will always protect your safety."

Thus, under the protection of Tianlang and five Immortal Emperors, Yang Huizhou continued his journey of training in the Immortal Realm, striving towards a higher realm.
