What he discovered was none other than Tiangang Stone.
The Tiangang Stone is extremely mysterious. It is a strange stone from heaven and earth. It is a treasure even in the divine realm.
At the beginning, his clone sensed the breath of Tiangang Stone in Mizong Mountain.
It's just that the Tiangang Stone is too mysterious. Even his clone cannot determine where the Tiangang Stone is.
It wasn't until Lingyun himself entered Mizong Mountain and saw the golden monkey that he got a glimpse of the truth.
Everyone thought that the golden monkey was the descendant trained by the Black Niu Old Demon.
Only Ling Yun saw the true nature of the golden monkey.
This golden monkey was transformed from the Tiangang Stone.
Tiangang Stone is different from ordinary stones. It is made of the yin and yang of heaven and earth. It is born with spirituality and can absorb the essence of heaven and earth to become stronger and stronger.
When it becomes powerful enough, it can take the form of a living being.
Therefore, it is not the Black Niu old demon who cultivates the "golden monkey", but the Black Niu old demon who has been cultivating with the help of the "golden monkey".
This golden monkey is not a golden monkey, but a Tiangang stone.
Ling Yun must get hold of such a treasure of heaven and earth no matter what.
In addition, the old black bull demon had a fierce battle with Shen Xingye and others before and suffered certain injuries.
Of course, to be precise, it was not Shen Xingye who hurt the old demon Black Niu, but Shen Xingye's sword energy from the top of the sword pavilion.
No matter what, the strength of the Black Bull Demon must be greatly reduced.
This is undoubtedly the best time for Ling Yun to take action.
The most important thing is that before doing this, Ling Yun could not kill a true soul powerhouse.
But now... Ling Yun took out the demon elixir of the Storm Sea Demon with his backhand.
As soon as he took out the demon pill, he felt the evil power in it.
This evil power will invade people's spiritual consciousness, eventually making them lose their sanity and turn them into killing machines.
But as soon as this power entered Ling Yun's body, it was swallowed up and dissolved by the "Eternal Devouring Heaven Jue", purified into pure energy, and turned into Ling Yun's spiritual energy supplement.
This demon pill is Ling Yun's trump card against the old demon Black Niu.
Ling Yun's most powerful killing moves are the "Guiyi Assassination Technique" and "Devil Purgatory Technique".
It's just that these two trump card killer moves will greatly overdraw your vitality.
It's different with the Storm Siren's demon elixir.
This demon elixir contains extremely powerful life energy.
Ling Yun could completely use the "Guiyi Assassination Technique" while extracting the life energy from the Storm Sea Demon Demon Pill to replenish the consumption.
Lost in the mountains.
The angry expression on the old black bull demon's face suddenly disappeared and was replaced by a proud smile.
Although he was injured, he was in a happy mood.
These human beings think that their methods are clever, but they don't know that this is what they deliberately let humans think.
The Earth Spirit Stalactite and the Colorful Stalactite were of extraordinary value, he knew this.
But he also knows that humans are dangerous.
These humans who enter Mizong Mountain every once in a while, although their cultivation is not very strong, they all possess terrifying killing moves.
If he really wants these humans to find nothing, it will only force them to search harder, and maybe they will discover his real treasure.
The real treasure is countless times more precious than the colorful stalactites.
If humans discover this thing, they will definitely use their trump card to deal with it.
In this case, even if he is a true soul-level monster, he still won't be able to withstand it.
So the best way is to let these human beings think they are smart and take away his treasure without having to fight him desperately.
Facts have proved that his strategy is also extremely clever.
These human beings would run away every time they got the Earth Spirit Stalactite and the Colorful Stalactite. They never fought for their lives and did not dare to conduct further exploration.
He was also happy to let these humans go.
But at this moment, he suddenly felt a sudden impulse, and there was some uneasiness in his gut.
He knew that this was a sign that a powerful enemy was coming.
"who?"
The eyes of the black bull demon burst out with cold light, shooting all around.
The group of humans had clearly left, who would come to attack him?
Almost at the same time.
A sharp sword light came through the air.
Ling Yun, who had gathered his breath and sneaked into Mizong Mountain, no longer concealed himself at this moment, and directly unleashed his trump card killing move to attack the Black Bull Old Demon.
The Guiyi Assassination Technique! What Ling Yun performed was the Guiyi Assassination Technique.
For a Heavenly Soul-level being like the Black Bull Old Demon, Ling Yun's other methods are meaningless. The only ones that are effective are the Guiyi Assassination Technique and the Heavenly Demon Purgatory Technique.
However, the Demon Purgatory Technique has too many consequences, so the Guiyi Assassination Technique is more suitable.
In an instant, Ling Yun's spiritual power surged by 50%.
His spiritual power is 150 billion kilograms.
A sharp increase of 50% would be 2300 billion catties.
Adding in the physical strength of one trillion kilograms and the dragon bone sword's thirteen hundred billion kilograms, Ling Yun's power reached forty-six hundred billion kilograms at this moment.
If it were at the peak of the Black Niu Demon, Ling Yun's power would still not be a match for the Black Niu Demon.
But now, the old demon Black Niu fought against Shen Xingye and others, which consumed a lot of strength, and the power he unleashed was only about five trillion kilograms.
He vaguely suppressed Ling Yun a little, but he couldn't crush Ling Yun.
Bang! The two sides collided.
The old black bull demon took a few steps back, while Ling Yun was sent flying dozens of meters.
"Human, you are so brave."
The old black bull demon was shocked and angry, "I can see that your cultivation level is not very high. The previous blow was a secret technique. This kind of secret technique cannot last long.
If you surrender, I will spare your life..." Normally, he would not have spared Ling Yun.
But now he is indeed injured. It is not cost-effective for him to fight Ling Yun at this time.
Ling Yun ignored him.
As soon as he cast the Guiyi Assassination Technique, all the spiritual energy in his body was drained.
At this moment, the "Eternal Heaven Swallowing Jue" was running wildly, swallowing the life energy in the Storm Sea Demon Demon Pill, and replenishing its consumption in the blink of an eye.
This storm siren's demon elixir definitely comes from the Zhuzhao level true soul storm siren.
Only this level of Storm Sea Demon Demon Pill can have such powerful life energy, which can replenish Ling Yun's consumption in an instant.
Then, Ling Yun launched the second Guiyi Assassination Technique against the old Black Bull Demon.
The expression of the old black bull demon changed.
This situation was undoubtedly beyond his expectation.
But he quickly calmed down.
Even so, Ling Yun still couldn't hurt him.
But this second Guiyi Assassination Technique is still just the beginning.
Next, Ling Yun relied on the demon elixir of the Storm Siren to launch eight consecutive assassination spells against the Black Bull Old Demon.
Without the Storm Sea Demon Demon Pill, Ling Yun would not have been able to perform the Guiyi Assassination Technique like this.
Such frequent use has undoubtedly brought Ling Yun's understanding of the Guiyi Assassination Technique to a new peak.
Buzz! The Guiyi Assassination Technique is advanced.
Ling Yun's Guiyi Assassination Technique finally broke through the limit at this moment and was promoted to the second level.
The first level of the unified assassination technique increases spiritual power by 50%.
At this second level, the increase in spiritual power is doubled.
The power of pure spiritual power reaches three trillion kilograms.
His ultimate strength has also increased to 530 billion kilograms! This is undoubtedly a huge leap compared to before.
This is also one of Ling Yun's plans.
The old demon Black Niu never imagined that Ling Yun's power would suddenly increase dramatically.
Caught off guard, his demon power was pierced by the Star Dragon Sword with a pop.
Then, Ling Yun's Star Dragon Sword pierced the chest of the old demon Black Niu and passed out from behind the old demon Black Niu.
