I was reborn as a young master in an invincible family of immortals

The black slime that spewed from the swamp beast's mouth, carrying a powerful evil spirit, surged towards us like a black torrent. Wherever the slime passed, the muddy water in the swamp sizzled and emitted a pungent stench, as if even the land itself groaned in pain under its erosion.

We dared not neglect our duties for even a moment, each casting our strongest defensive spells to fend off this deadly attack. I harnessed the spiritual energy from the inherited secret manual to its fullest potential, erecting layer after layer of golden spiritual shields before me. The shields shimmered like sturdy walls, attempting to block the onslaught of the black slime.

Lin Xiao brandished his sword, muttering something to himself. The sword instantly shone brightly, unleashing a series of interwoven sword energies that formed a defensive barrier. He stared intently at the incoming black slime, his eyes etched with determination and resolve. He swung the sword continuously, reinforcing the defensive net.

Su Yao quickly formed seals with her hands, and a soft glow emanated from her body. This light continued to spread, enveloping us all. Enveloped by this light, it seemed as if a secluded space had been formed, capable of cushioning the impact of the black slime. She closed her eyes tightly, concentrating all her energy on maintaining this defensive spell. Sweat gradually seeped onto her forehead, but she ignored it, completely focused on protecting everyone.

However, the power of the black slime was far too great. When it struck our defenses, it emitted a deafening roar, and the entire swamp seemed to tremble violently. I felt a massive force slam into the spiritual shield, causing its golden light to flicker and crack, as if it would shatter at any moment.

The sword net defense barrier on Lin Xiao's side was also under tremendous pressure. The sword energy was constantly dispersed by the black mucus and then constantly re-condensed, but the range of the sword net was gradually shrinking and it was about to collapse.

Su Yao's defensive light was also hit hard. The light became weaker and weaker, her face became paler, and her body trembled slightly, but she still gritted her teeth and tried her best to maintain this last line of defense.

"Everyone hold on! Let's work together to attack its weaknesses. We can't let it suppress us like this!" I shouted loudly, my voice sounding particularly firm amid the noisy roar.

Everyone nodded upon hearing this, their eyes alight with fighting spirit. We knew that blindly defending would lead to our own demise. Only by burning our boats and proactively identifying the swamp beast's weaknesses and delivering a fatal blow would we have a glimmer of hope.

While fending off the black slime, I carefully observed the swamp beast's every move. I noticed that after each spurt of slime, it paused briefly, as if gathering strength for its next attack. Furthermore, there was a darker scale beneath its abdomen, its luster slightly duller than the surrounding scales. Perhaps that was its weak spot.

"Everyone, pay attention to the slightly darker scale under its abdomen. That may be its weakness. When it pauses next time, we will concentrate our attacks there!" I quickly informed everyone of this discovery.

Lin Xiao, Su Yao, and the other Xianzong disciples listened to my words and immediately locked their sights on the belly of the swamp monster. They adjusted their attack preparations and waited for the best opportunity to arrive.

Finally, the swamp monster spewed out another stream of black mucus, and then there was a brief pause as I expected.

"Now!" I shouted, gathering most of the remaining spiritual energy in my body into my palm, transforming it into a blazing spiritual flame, and swooped down towards the dark scales beneath the swamp beast's abdomen. The flame grew stronger as it flew, burning and distorting the air wherever it passed.

Lin Xiao followed without hesitation, his figure rushing towards the beast like lightning, brandishing his sword, each swing releasing a stream of incomparably sharp sword energy. These sword energies shot towards the beast's weak spot like meteors, aiming directly at the dark scale, trying to break it in one fell swoop.

Su Yao wasn't idle either. She took a deep breath and formed seals with her hands again, this time casting a spell to assist in the attack. A silver light flew out from her hand and merged into Lin Xiao's and my attacks, instantly increasing the power of our attacks, making the spiritual flames even hotter and the sword energy even more fierce.

Other disciples of the Immortal Sect also cast their strongest attack spells one after another. All kinds of colorful spiritual lights converged towards the weakness of the swamp monster, forming a powerful torrent of attack.

The swamp monster seemed to sense the danger, and a hint of fear flashed in its huge eyes, but it was too late to dodge.

Our attacks rained down on the dark scale beneath its belly. With a loud bang, the scale shattered instantly under our combined attack, and a stream of black blood gushed out from the shattered area.

The swamp monster roared in agony, its massive body trembling violently as it tumbled madly across the swamp, splashing large swathes of mud and water. It tried to cover the injured area with its claws, but to no avail. The black blood that continued to flow from the wound gradually drained away its strength.

"Keep attacking, don't give it a chance to breathe!" the leading elder shouted loudly, his voice sounding particularly loud in this chaotic battlefield.

We pursued the wounded swamp monster and continued to attack it. Under our fierce attack, it gradually lost its ability to resist and finally collapsed in the swamp, unable to move.

Everyone breathed a sigh of relief, but we didn't have time to rest, because the familiar breath similar to the inheritance was still attracting me.

"Don't relax too quickly, there may be important secrets related to the Shadow Cult and inheritance hidden here. We have to look for them quickly." I said, and then walked towards the direction where the breath came from.

Lin Xiao, Su Yao and other disciples of the Immortal Sect also followed, and we explored the swamp carefully.

As we went deeper, the aura grew stronger. Finally, in a secluded corner of the swamp, we discovered an ancient stone door, sealed by layers of restrictions. The door was engraved with various strange runes and patterns. These runes shone with an eerie light, as if telling an ancient and mysterious story.

And that aura similar to the inheritance came from behind this stone gate.

"This stone gate doesn't look simple. The restrictions on it are very strong. Everyone, be careful." Su Yao reminded softly, her eyes scanning back and forth between the runes on the stone gate, trying to decipher their meaning.

We gathered around the stone gate, carefully examining it and the restrictions placed upon it. The leading elder frowned and said, "This restriction appears to be an ancient Shadow Cult seal. Breaking it won't be easy. However, now that we've come this far, we must find a way to open it and see what secrets lie within."

I looked at the stone door, thinking about how to break it. Suddenly, I remembered that the inherited secret manual mentioned a method for breaking the ancient seal. Maybe I could give it a try.

"I have a solution. Everyone, step back first. I will try to use the method in the inherited secret book to break the restriction on this stone door." I said, and then asked everyone to retreat to a safe distance.

I walked up to the stone gate and began to slowly circulate the spiritual power in my body according to the method of breaking the seal recorded in the inherited secret book, injecting the spiritual power into the runes on the stone gate in a specific way.

As I poured my spiritual energy into it, the runes on the stone gate glowed brighter and brighter, as if reactivated. But at the same time, a powerful recoil force emanated from the stone gate, attempting to push me back. I gritted my teeth, steadied myself, and continued to pour my spiritual energy into it.

Lin Xiao and Su Yao looked at me nervously from the side. They knew that this was a critical moment. If I could successfully break the ban, perhaps I could uncover the shocking secrets behind the Shadow Cult and its inheritance.

After some strenuous effort, the runes on the stone door suddenly glowed brightly, and the recoil force vanished. Then, the stone door slowly opened, and a rich aura of spiritual energy washed over us. At the same time, a mysterious voice echoed in our ears: "Fated ones, you have finally arrived. Within lies the ultimate secret of the Shadow Cult and the truth about inheritance..."

We looked at each other, feeling both nervous and excited, and then carefully walked into the stone gate, ready to face the secret that was about to be revealed. What impact this secret would have on us and the entire world of cultivation was still unknown.
