The ruins of the ancient city of the Golden Wolf are vast and immense, enough to accommodate more than 100 million living beings living in it.

After entering the ancient city, the eighty-two disciples all dispersed and began to search for the traces of the 'Bad Blood Demon Clan'.

"Lei Yugang, tell me the details of the three helmsmen."

Yun Qingyan rushed to the depths of the ancient city as he said to Lei Yugang's soul.

"The three of them are all cultivators at the peak of true immortals, and they are called Baiyun Spring, Feng Mo, and Luo Sha!"

"As Zhang Chuxiu said, these three people are one of the few people in the Thundercloud Sect who have no faction!"

"But they don't have factional colors, it's not because of how noble they are, but because they want to be left and right, they want to get benefits from my father, and they want Zhang Chuxuan to win them over!"

Lei Yugang's voice sounded in Yun Qingyan's mind.

Speaking of these three people, Lei Yugang's tone was still a little disgusted.

"But master, because they want to be left and right, and please both sides, so the master doesn't have to worry that they will be unfavorable to you!"

"With their shrewdness, they naturally guessed that 'Zhang Yichen' is Zhang Chuxuan's son! If nothing else, their attitude towards their master will be businesslike. ”

"Neither will please the master nor offend my father's side. will not suppress the master and offend Zhang Chuxuan's faction. ”

After listening to Lei Yugang, Yun Qingyan forcibly suppressed a certain thought in his heart.

"Perhaps, I thought too much." Yun Qingyan muttered in his heart.

……

The Bad Blood Demon Clan is a race that is day and night, and is very good at hiding.

Including Yun Qingyan, eighty-two disciples of the Thunder Cloud Sect had already penetrated deep into the central region of the ancient city.

But none of them found any trace of the Bad Blood Demon Clan.

"I haven't met a bad blood demon clan for so long, it seems that things are the same as we guessed, there are not many bad blood demon clans found here, and their cultivation is not high!"

Inside Yun Qingyan's divine sense, a scene of dialogue appeared.

It was a private conversation between the two disciples of Zhang Chuxuan's faction after they met.

"Yes, definitely! Otherwise, the people who come here to kill demons will not be our immortal disciples, but the true disciples who will directly dispatch them! The other nodded in agreement.

"Since the cultivation of the Bad Blood Demon Clan here is not high, we still continue to act separately, so as not to have a scramble after encountering the prey."

The two who met privately separated again.

Yun Qingyan also continued to go deeper into the ancient city at this time.

Yun Qingyan's divine sense has been put to the limit, and he is looking for a place that is hidden enough to break through.

He wasn't too concerned about this mission.

Thundercloud Fantasy Realm, as long as he is a true disciple, he can participate, and he can completely say that he has broken through to the true immortal and simulates the cultivation of the true immortal in public.

Of course, if he encounters the Bad Blood Demon Clan, Yun Qingyan will not let one go.

In the blink of an eye!

Half an hour has passed!

Yun Qingyan's divine consciousness found a cave with a large volume, long, wide, and high, all over 100 meters!

Inside the crypt, there are seventeen bad blood demon clans.

Each of these seventeen bad blood demon clans exuded a pungent smell of blood, and the black smoke that turned into anger was constantly diffusing from them.

Because the Bad Blood Demon Clan is all day and night, these seventeen Bad Blood Demon Clans are still sleeping in the crypt at this time.

In addition to the seventeen Bad Blood Demon Clans, there are also piles of corpses and bones in the crypt, and there are no less than a thousand human skulls alone.

In Yun Qingyan's eyes, a murderous intent flashed for the first time.

Yun Qingyan followed the entrance of the crypt and quietly sneaked into the crypt out of nowhere.

Rumble!

Yun Qingyan shot directly, and the Origin Sword slashed towards the nearest Bad Blood Demon Clan.

Whew!

In one shot, this bad blood demon clan was cut in two.

A black jade stone fell out of its heart and fell to the ground with a bang.

"Who?"

The sound of movement instantly woke up the other sixteen Bad Blood Demon Clans.

"Terran breath! You are a Terran! ”

"Damn Terran, you actually killed one of our companions?"

These sixteen bad blood demon clans, after waking up, looked at Yun Qingyan with a sinister look in their eyes.

Swish! Swish! Swish!

Sixteen figures rushed towards Yun Qingyan almost at the same time.

As they struck, the black smoke that permeated their bodies became several times thicker at once.

The entire crypt, in an instant, was filled with black smoke from this aura.

Yun Qingyan's attention at this time was no longer on the sixteen bad blood demon clans, but looked at the black jade that fell to the ground in a bit of a daze, "The bad blood demon clan in the pseudo-fairy realm has actually bred demon cores......

Most demon clans, like the human race, have a heart.

The heart is also their root!

A very small number of great demons who have cultivated to the heavens will transform their hearts into demon cores.

The demon core is invaluable, not only can it be directly refined, but it can also be turned into cultivation! It can also be used as the eye of some extremely powerful formations.

In addition, the demon core also has a special ability, and because of this special ability, the value of the demon core has risen infinitely.

After its energy is depleted, it can also inject energy into it and store it for a long time.

This is equivalent to a water bag, open it when you are thirsty and take a sip. After drinking, you can refill the water bag with water.

Suppose Yun Qingyan now has a demon core.

Will he be able to store the excess energy in the demon core? Wait until you need it, and then absorb it?

With a 'whoosh', Yun Qingyan's whole person turned into a phantom, rushed directly to the black demon core, and grabbed it in his hand.

"Sure enough, it's a demon core!"

After feeling the power of the fairy spirit coming from inside the demon core, Yun Qingyan muttered with a little joy.

"If it's not surprising, this is still a mutant demon core!"

Under normal circumstances, it is impossible for the demon clan below the Xuan Immortal to breed demon cores.

Because the demon core is transformed from the heart, and the metamorphosis ...... It often requires extremely advanced cultivation!

The demon core in Yun Qingyan's hand is just the demon core of the pseudo-fairyland, even if it is Yun Qingyan, it is the first time to see the demon core of the pseudo-fairyland!

Obviously, this is a mutated demon core!

The demon core is precious, and the mutated demon core is even more precious!

Because of the mutant demon cores that appeared in the fairy world, almost every one ...... They are all demon cores that can evolve!

"I'll test this demon core with you first!"

Yun Qingyan muttered, and his big hand grabbed directly at the nearest Bad Blood Demon Clan.

"Swallowing the Heavens—"

Yun Qingyan burst out with a roar, and sucked out the energy in the body of the Bad Blood Demon Clan planted by his hand.

The energy in Yun Qingyan's body has reached the limit of what it can hold, and if it is devoured, it will only cause itself to explode and die!

Therefore, at the same time as Yun Qingyan devoured it, the other hand had already injected energy into the demon core.

Bite! The black demon core appeared with a soft roar, storing all the energy that Yun Qingyan devoured with the Heaven Devouring Secret Technique.
