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

Led by Li Yunfei, the five flew westward for over 100,000 miles and finally entered a mountain forest spanning tens of thousands of miles. Through their divine senses, they could detect the presence of many Venerable Realm demonic beasts.

However, the aura released by the five suppressed the restless group. Soon, they arrived above a deep canyon. The five exchanged glances and then plunged into the canyon.

The canyon isn't very deep. At the bottom, it's about 20,000 to 30,000 meters deep. There's no sunlight here anymore, but since everyone here is a Venerable One, their vision is fine.

Li Yunfei led the group to a stone wall, made a hand seal, and ripples appeared on the stone wall. Li Yunfei went in first, and the others followed.

Upon entering, they discovered a huge grotto filled with incredibly rich spiritual energy. Deep inside, there was a small opening, which they followed down cautiously.

The cave was very long, and it took them an hour to walk through it. Along the way, they encountered several traps, killing formations, and illusion formations.

Trapping formations and illusion formations are relatively easy to break, as they don't have much offensive power. Anyone with a basic understanding of formations can easily break them. But killing formations are a different story.

These formations should all be at least at the Void Returning Realm level, having withstood at least tens of thousands of years of erosion, and still possess the power of the Nascent Soul level.

For example, Yang Hongbo recognized the killing formation they were facing now. Due to the passage of time, it was missing a corner, which greatly reduced its power, but it still had the destructive power of a peak Nascent Soul cultivator.

Although the killing formation was greatly reduced in power, it was still too lethal to the teammates who were at the low level of the Nascent Soul stage. In just a short while, these people were covered in blood.

Left with no other option, Yang Hongbo released Tianlang, who surrounded the four people from the front and back, blocking the subsequent attacks for them.

The incomplete formation was quickly broken, and the four hurriedly thanked Yang Hongbo. Yang Hongbo waved his hand, saying, "We're teammates, isn't it only natural to help each other?"

"That's not how it works. If you don't save us, we'll at least be missing an arm or a leg, and even if we find the treasure, we won't be able to do anything about it. If we do find the treasure later, Venerable Yang should take the lion's share first, and we'll just get a small cut!"

Since the four of them had reached an agreement, Yang Hongbo couldn't change it, so the five of them continued walking forward.

Soon, a larger grotto appeared ahead, with a pool of water in the middle, blocking out an entrance to the cave behind it.

The water in the pool was very yellow and turbid, making it impossible to see what was in it or to use one's divine sense to investigate.

Just as everyone was about to fly over, Yang Hongbo suddenly stopped them. He took out a magical artifact and commanded it to fly to the other side. Just as it flew over the pool, a fleshy vine emerged from the pool, wrapped around the artifact, and dragged it into the water.

Then, a huge creature appeared in the pool—a giant toad. Its body was covered with pustules, from which yellow pus was flowing. That must be why the water in the pool was yellow.

This toad actually possessed the cultivation level of the early Nascent Soul stage, which made everyone feel troubled. They quickly looked to Yang Hongbo, who had the highest cultivation level.

"You all retreat back to the cave first, and let my pet and I figure out a way to kill this monster."

"Then Venerable Yang, be careful!" The four people stepped back.

After the four of them retreated to a safe place, Yang Hongbo patted Tianlang's head and said with a solemn expression, "Tianlang, this toad is not simple. It has the cultivation of the early stage of the Nascent Soul realm, and its pus has corrosive power. We have to be careful."

Sirius let out a low growl, his eyes flashing with ferocity, as if responding to Yang Hongbo.

Yang Hongbo formed hand seals and chanted incantations, unleashing a barrage of spells like meteors towards the toad. The toad, not to be outdone, spewed out plumes of yellow poisonous mist, which clashed with the spells, producing a sizzling sound. Wherever the poisonous mist reached, it corroded small pits into the stone walls.

"Tianlang, attack!" Yang Hongbo shouted, and Tianlang charged towards the toad like an arrow released from a bow, its sharp claws viciously grabbing at the toad's body. The toad reacted extremely quickly, flicking its long tongue and sending Tianlang flying.

Taking advantage of the opportunity, Yang Hongbo launched another attack, slashing a massive flaming sword at the toad. The toad shrank back, dodging the attack, and then lashed out at Yang Hongbo with its long tongue like a whip. Yang Hongbo dodged to the side, and the tongue struck the stone wall, instantly splitting it open with a large gash.

"What a formidable creature!" Yang Hongbo thought to himself in surprise, his hands constantly changing hand seals as he shot ice arrows at the toad. Suddenly, the pustules on the toad's body burst open, spewing out streams of yellow liquid that melted the ice arrows.

"Tianlang, attack its eyes from the side!" Yang Hongbo shouted. Upon hearing this, Tianlang quickly circled around to the toad's side, leaped up, and pounced on the toad's eyes. Sensing the danger, the toad immediately closed its eyes, its long tongue also curling towards Tianlang.

Just then, Yang Hongbo seized the opportunity and unleashed his strongest spell—Nine Heavens Thunderclap. Dark clouds filled the sky, and thick bolts of lightning struck the toad. Struck by the lightning, the toad trembled, and its long tongue moved much more slowly.

Taking advantage of the opportunity, Tianlang clawed at the toad's eye. The toad cried out in pain, its long tongue flailing wildly. Yang Hongbo launched another attack, unleashing a series of sword energies aimed at the toad's vital points.

After a fierce battle, the toad finally collapsed, unable to hold on any longer. Yang Hongbo and Tianlang were also exhausted and panting heavily, both bearing injuries of varying degrees.

"Finally, we've dealt with that monster." Yang Hongbo breathed a sigh of relief and asked Tianlang, "How badly are you injured?"

Sirius let out a low growl, indicating that he was alright. Yang Hongbo took out some pills and gave them to himself and Sirius to help them recover their strength.

"Let's keep going," Yang Hongbo called out to the four people hiding in the cave. The four cautiously came out and breathed a sigh of relief when they saw that the toad was dead.

"Venerable Yang, you are truly amazing!" someone exclaimed.

"Yes, if it weren't for you, we wouldn't have been able to get through here at all," another person chimed in.

Yang Hongbo smiled and said, "We're all on the same team, no need to be so polite. Let's continue deeper into the cave; perhaps there are even more treasures waiting for us."

The group continued forward along the cave entrance, remaining highly vigilant the entire way. They hadn't gone far when a hissing sound suddenly came from ahead.

"Everyone be careful, there might be danger," Yang Hongbo warned.

No sooner had the words left his mouth than a huge snake emerged from a crevice in the rocks beside him. This snake was dozens of feet long, its body as thick as a water bucket, its scales gleaming with a cold light, and it hissed as it flicked its tongue.

"Another Nascent Soul stage demon beast!" Everyone was shocked.

"This snake looks even more dangerous than that toad. Everyone be careful," Yang Hongbo said solemnly.

The giant serpent opened its blood-red maw and lunged at the group. Yang Hongbo and Tianlang quickly rushed forward and engaged the serpent in a fierce battle. The serpent's body was incredibly agile, sometimes coiling and sometimes attacking, making it difficult for Yang Hongbo and Tianlang to defend themselves.

"Don't just stand by and watch, attack together!" Yang Hongbo shouted. Hearing this, the four of them unleashed their spells, bombarding the giant snake. Enraged by the attack, the giant snake roared, its body trembling, sending everyone flying.

"This can't go on; we need to find a way to stop it," Yang Hongbo said.

"Venerable Yang, I have an idea," one person said. "We can distract it, and then you can find an opportunity to attack its vital point."

Yang Hongbo nodded: "Okay, let's do it that way."

The group acted according to plan, with the four of them spreading out around the giant snake, constantly launching attacks to draw its attention. Yang Hongbo, on the other hand, quickly circled behind the giant snake, looking for an opportunity.

While the giant snake's attention was drawn to the four people, Yang Hongbo seized the opportunity and unleashed a sharp sword aura, slashing towards the snake's vital spot. The giant snake sensed the danger and tried to dodge, but it was too late. The sword aura struck the snake precisely at its vital point, and the snake let out a scream, its body convulsed, and then it collapsed to the ground.

"We've finally dealt with this giant snake." Everyone breathed a sigh of relief.

"Let's keep going. We don't know what dangers await us ahead," Yang Hongbo said.

The group continued deeper into the cave, encountering numerous traps and monsters along the way, but they overcame them all. However, when they reached a spacious stone hall, they suddenly heard a deep roar.

"What's that sound?" one person asked in alarm.

"It sounds like some kind of powerful monster," another person said.

The group cautiously approached the source of the sound, and as they entered the depths of the stone hall, they saw a gigantic bear standing there. This bear was several meters tall, incredibly strong, with fur like steel needles, and exuded a powerful aura.

"Another giant bear at the Nascent Soul stage!" Everyone's hearts sank.

"Don't panic, everyone, let's go together," Yang Hongbo said.

Everyone unleashed their spells, bombarding the giant bear. The bear roared, wielding its massive claws to deflect all the attacks. Then, the bear pounced on the group with incredible speed.

Yang Hongbo and Tianlang quickly rushed forward and engaged the giant bear in a fierce battle. The giant bear was extremely powerful, and each attack put immense pressure on Yang Hongbo and Tianlang.

Left with no other option, Yang Hongbo had to use a defensive magical artifact. Now, the giant bear's attacks were no longer effective against him.

"Everyone, try to attack its eyes and nose; these are its weak points," Yang Hongbo shouted.

Upon hearing this, the four adjusted their attack direction, aiming their attacks at the giant bear's eyes and nose. The giant bear was somewhat flustered by the group's attacks, but it quickly regained its composure and launched another attack.

After a fierce battle, the group gradually became exhausted. The giant bear, however, fought with increasing ferocity and ferocity.

"If this continues, we'll all die here. We need to find a way to escape," one of them said anxiously.

"Don't panic, everyone. I have a magical treasure that might be able to subdue this giant bear," Yang Hongbo said.

As he spoke, Yang Hongbo took out a shimmering magical artifact, chanted incantations, and then threw it towards the giant bear. The artifact transformed into a massive light screen in the air, enveloping the bear within it. The bear was trapped by the light screen and unable to move. Then, the artifact slowly shrank, taking the bear into its pouch.

"Alright, let's go!" Yang Hongbo shouted.

Taking advantage of the opportunity, the group quickly ventured deeper into the cave. The road ahead was uncertain; they didn't know what dangers awaited them, but they knew that only by continuing forward could they possibly find the treasure and escape this perilous place alive.
