Later generations who want to continue opening apertures can hardly find suitable materials.
They had no choice but to change the aperture opening secret techniques and start opening apertures from scratch.
The aperture opening secret technique recorded in the Hunyuan Heavenly Scripture is called the Chaos Aperture Opening Secret Method.
Using this secret method to open apertures only requires the crystal core of a Chaos Beast.
Opening the first aperture requires a one-star Chaos Beast crystal core, and the second aperture requires a two-star Chaos Crystal Core.
The third aperture requires a three-star crystal core, and the ninth aperture requires a nine-star Chaos Crystal Core.
As for opening the tenth aperture, it requires the crystal core of a Chaos King Beast.
Although Chaos Crystal Cores are also very precious, there are still targets to be found after all.
On the Chaos Continent, the number of Chaos Beasts is as numerous as the hairs on an ox.
As long as you are strong enough, you can kill as many as you want.
Having a target makes things easier.
He was afraid that some aperture opening secret techniques would require finding some unknown materials.
That would be too difficult.
It would completely depend on luck.
It is entirely possible that you may not find the corresponding materials in your entire life.
Zhang Yuhe silently recalled the contents of the second volume of the Hunyuan Heavenly Scripture.
He suddenly discovered a problem.
This cultivation method seems to be going against Chaos Beasts.
Not only does the aperture opening secret technique require the use of Chaos Beast crystal cores, but even the promotion of natal magic treasures requires Chaos Beast crystal cores.
Moreover, in the second volume of the Hunyuan Heavenly Scripture, there is also a recorded Dao technique.
It also requires the assistance of Chaos Beast crystal cores to be able to cultivate.
The first volume of the Hunyuan Heavenly Scripture records the Nine Heavens Hunyuan Sword Formation supernatural power.
And in the second volume, a Dao technique is recorded.
It is called Chaos Returning to Emptiness.
Dao techniques are the sublimation of supernatural powers.
To cultivate Dao techniques, you not only need to comprehend the laws to perfection, but also need to open the origin of the Dao.
In addition, you need the corresponding materials and formation support to be able to cultivate successfully.
However, this matter is still too early for him.
Whether it is opening the origin or perfecting the laws, those are things for the distant future.
For the current Zhang Yuhe, it is more practical to open the first aperture first.
As long as he opens one aperture, then he can start comprehending the first law.
Opening the first aperture requires a one-star Chaos Beast crystal core, and promoting the natal magic treasure requires nine one-star crystal cores.
Anyway, Lian Zhengyu told him before that he could take any materials from the treasure vault to promote the natal magic treasure to a celestial artifact.
Then it shouldn't be a big problem for him to take one more one-star crystal core, right?
Thinking of this.
Zhang Yuhe stood up and quickly flew towards the treasure vault.
...
Zhang Yuhe quickly arrived at the sect's treasure vault. After he showed his identity jade token.
He quickly received ten one-star Chaos Beast crystal cores.
The smoothness of the process was completely beyond his expectations, and he did not encounter any difficulties.
The senior brother in charge of guarding the treasure vault didn't even ask and directly threw the things to him.
"This sect is not bad."
Zhang Yuhe silently gave the sect a good review.
Although the Dao Saint Sect is currently in a period of decline, the disciples are still very united.
The dog-blood incident he imagined did not happen.
He took a Chaos Beast crystal core in his hand and checked it.
He saw that the surface of the crystal core emitted a chaotic and violent aura.
Through the crystal core in his hand, he could imagine the power of the Chaos Beast.
According to normal classification, one- to three-star Chaos Beasts correspond to the early to late stages of True Immortals.
However, when actually fighting, unless the immortal body is newly formed.
Otherwise, even the late stage of True Immortals may not be able to kill a one-star Chaos Beast.
Because Chaos Beasts are too tough.
According to descriptions in the classics, Chaos Beasts are not only huge in size, but also have thick skin and flesh.
The key is that they are almost immune to the supernatural powers and law damage of monks of the same rank.
To kill Chaos Beasts, immortals must either have strength that can suppress Chaos Beasts.
Or they must comprehend the laws to a higher realm, or comprehend some special laws.
Of course, the best way is to cultivate an immortal body.
Even if it is only the initial formation of an immortal body, you can rely on brute force to crush Chaos Beasts below three stars.
It is a pity that it is too difficult to refine an immortal body.
According to Zhang Yuhe's plan, he put the cultivation of the immortal body at the very end.
This thing of the immortal body is not afraid of your strong talent, nor is it afraid of your high comprehension.
Without the corresponding natural treasures to assist, even gods will be useless.
...
After Zhang Yuhe left the treasure vault.
He was thinking about whether to find a place to open the first aperture first.
Suddenly, his expression changed.
A crystal clear mirror appeared in his hand.
Immortal Transmission Mirror.
The common communication tool for immortals, in the same sea area, can achieve instant communication.
Zhang Yuhe pinched the magic formula and pointed his finger towards the Immortal Transmission Mirror.
Xie Mingyuan's projection quickly appeared in the mirror.
"Junior brother, are you ready? We are about to set off."
"Okay, I'll wait outside the mountain gate."
Zhang Yuhe put away the Immortal Transmission Mirror and quickly flew towards the outside of the mountain gate.
After a while, a stream of light streaked across from a distance.
An exquisite flying boat appeared in his sight.
Zhang Yuhe leaped onto the flying boat in one step.
Xie Mingyuan pinched the magic formula, the flying boat turned into a stream of light, and continued to fly into the distance.
Standing on the flying boat, Zhang Yuhe asked.
"Senior brother, I wonder if the two ancestors, Wu Yingguang and Xiong Yuanzhong, are still in the sect?"
As far as he knows, Yufan Heaven has given birth to a total of three ascended monks.
But apart from Xie Mingyuan, he has never heard of the other two's news.
That's why he asked.
Xie Mingyuan was silent for a long time before slowly opening his mouth and said.
"Senior brother Wu Yingguang died in the Immortal Fall Cataclysm on the Chaos Continent as early as 800,000 years ago."
"As for senior brother Xiong Yuanzhong."
Speaking of Xiong Yuanzhong, Xie Mingyuan seemed to be in a very heavy mood.
He paused for a while before continuing to say.
"When I first arrived in the Immortal Realm, senior brother Xiong was already in the late stage of True Immortal."
"I was able to gain a foothold in the Immortal Realm entirely because of senior brother Xiong's guidance along the way."
"It's a pity that 100,000 years ago, senior brother Xiong suddenly and unexpectedly fell when he went out to find opportunities."
"After much investigation, I suspect that the Ouyang family killed senior brother Xiong."
Speaking of the Ouyang family, Xie Mingyuan's tone was obviously filled with endless hatred.
"Senior brother, are you sure it's the Ouyang family?"
"It's almost certain."
"Take it slowly, we will definitely be able to avenge senior brother Xiong in the future."
Although Zhang Yuhe had never met Xiong Yuanzhong himself, he was also an ascended monk of the Dao Saint Sect of Yufan Heaven.
As long as there is a chance, he naturally cannot easily let go of this revenge.
