Looking at the spiritual veins in front of him that had turned into a pile of debris, Cao Fan secretly sighed in his heart the high price he had paid for using the law of time.

It seems that his next focus is to try to find more spiritual veins.

However, before that, he had to work with Tu Penghai to lay a spiritual vein at the core of the Cangyun Sect's Sect Protector Array.

During the time when Cao Fan entered the Taishang Nine Realms of penance, Tu Penghai always maintained a high degree of vigilance and guarded the safety of the sect.

Seeing Cao Fan out of the customs, Tu Penghai was a little dumbfounded while being excited.

Ten days ago, the sect master was only a fifth-level cultivator of Qi training, how could he reach the realm of Qi Cultivation Great Perfection at such a point.

Thinking of Yu Xiaochuan, who was almost as perverted in his cultivation, Lao Tu couldn't help but sigh that the talent of this master and apprentice was really good.

Recalling that he himself was still complacent in five years from the fifth level of Qi cultivation to the Great Perfection of Qi Training, and even became a disciple of Tianjiao who ranked in the top three in the sect's qualifications because of this, Tu Penghai couldn't help but feel that his old face was a little hot.

However, this is definitely a great thing for the Cangyun Sect, Tu Penghai happily congratulated Cao Fan on his cultivation, and even prepared to hold a small-scale celebration to celebrate.

Now is an important stage of the Great Cultivation of the Whole People, and of course Cao Fan doesn't want to engage in these bells and whistles. Even if he succeeded in building the foundation, he was not going to hold any celebrations.

He directly told Tu Penghai about laying the spiritual veins at the core of the Sect Protector Great Array, and shocked the latter again.

With the spiritual vein, the Cangyun Sect really looks like a big sect.

It's just that the spiritual veins are really extremely rare. Every new spirit vein, once discovered, will immediately be directly controlled by the nearby fourth-level great sects.

Even if there are spirit stones, they are difficult to buy at auction.

This kind of important strategic resource, no sect will take it out for auction.

Tu Penghai didn't ask Cao Fan about the origin of the spiritual vein, the sect master could get the spiritual vein, so he just had to lay it out.

Laying the spiritual vein is much faster than arranging the Great Sect Protector Array, all Cao Fan and Tu Penghai have to do is to choose a suitable location, cast a spell to make a long and deep enough tunnel, release the spiritual vein, and then use a few simple formations to guide the spiritual power generated by the spiritual vein to various formation nodes in time, and finally spread to all corners of the entire internal area of the sect.

The collection of the spiritual vein is the most difficult, after all, it is a hill that stretches for five miles, and at least it has to be collected by a half-step Yuan infant powerhouse with some auxiliary formations or powerful talismans such as giant power talisman and mountain moving talisman.

Only the largest five-star storage bag can hold an entire spiritual vein.

It's not too simple to place the spiritual vein, just calculate the landing point and follow the normal method of taking things.

After the spiritual veins were arranged, the two of them also set up several other concealment formations, completely hiding the aura of the spiritual veins at the core of the formation.

It's still far from the time to expose the spiritual veins of the Cangyun Sect.

A few hours later, all the people in the entire Cangyun Sect who were in retreat and cultivated felt a significantly enhanced aura atmosphere.

Everyone thought that the sect had activated some new spirit gathering arrays, and hurriedly took advantage of the rich aura to cultivate with all their might.

Tu Penghai knew that Cao Fan was going to attack the realm of the foundation building period, and he had to protect the Fa by his side no matter what.

Yu Xiaochuan almost died when he hit the foundation building realm before, and Tu Penghai was very worried that Cao Fan, who was a master, would also encounter the same dilemma.

Cao Fan chose to build the foundation on the peak of Tianwu Peak.

After he took the four-star Zhuji Dan, he activated the Heavenly Fortune Creation Technique.

There are also seven spirit gathering arrays arranged by Tu Penghai around him, plus the aura support provided by the spirit veins, the aura atmosphere that Cao Fan used to impact the foundation building realm is almost perfect.

Above Cao Fan's head, a rapidly rotating vortex of spiritual energy kept rolling the spiritual energy mist towards Cao Fan's body.

Above the aura vortex, the air currents in the air were also swirling rapidly, and they were soaring.

Soon the peak of the Heavenly Mist Peak formed a very shocking spectacle, and the spiraling cyclone reached thousands of feet, and later the entire sky was completely obscured.

Countless Heaven and Earth Spiritual Qi Essence descended sharply through this huge cyclone, merging into the lowest spiritual energy vortex, and then instilled into Cao Fan's body.

Cao Fan obviously felt the impact of the powerful spiritual qi flow, and could only do his best to run the exercises at high speed, transforming all kinds of spiritual qi entering his body into heavenly luck spiritual power and converging it to the lower dantian.

Tu Penghai was stunned from the sidelines.

If he hadn't seen it with his own eyes, he would never have imagined that a Qi cultivation period cultivator would have such an earth-shattering momentum when he was impacting the Foundation Building Realm.

Attracting a large amount of heaven and earth aura to converge, this is a vision that only existed when the Great Perfection Monk of the Jiedan attacked the Yuan Infant Realm.

Because the potential value of the law cultivation had already reached the requirements of foundation building, Cao Fan did not have an overfill of spiritual power in his body.

The Heavenly Fortune Spiritual Power in his body was constantly compressed and condensed under such circumstances, which was something that countless monks dreamed of.

The spiritual power that each realm dantian can hold is limited, and if the transformed true element is more condensed when breaking through, the easier it will be to cause a crushing advantage in the face of opponents of the same level.

Refined to a certain extent, it can even easily skip the challenge.

"It's still a little bit off. Cao Fan said to himself.

Tu Penghai was already numb from shock, and he inhaled so much aura at once, not to mention a Qi Cultivation Great Perfection cultivator, even a strong person who built the foundation of the Great Perfection Realm couldn't bear it.

In this case, Cao Fan is not enough.

Oh my God, what kind of anti-heaven existence did the ancestor bring to the Cangyun Sect!

Thunderclouds suddenly and quickly condensed in the sky, and there was even a faint sound of thunder in the clouds.

Tu Penghai's eyes widened, although he had been shocked many times by the various visions caused by the sect master's foundation building this time, but what was this now?

Could it be a thunderstorm?

It's impossible!

As we all know, monks will only attract thunder tribulation when they break through to the Yuanying realm, and even Tu Penghai himself has never experienced thunder tribulation.

It should be said that he didn't even have a chance to see the half-step Yuan Infant Realm's cultivator's tribulation process.

And today, the sect master is just building a foundation, and he actually ......

"It came at the right time.

Elder Taishang, you hurry up and retreat, so as not to be affected by the thunderstorm!"

Cao Fan suddenly hurried to Tu Penghai.

Tu Penghai nodded, and his figure flew backwards hundreds of zhang away, leaving the top of Tianwu Peak.

If this was a thunderstorm, he was so close to the sect master at the moment, he would definitely suffer a punishment thunderstorm.

His cultivation during the Dan period should be fine, but it will inevitably affect the power of the thunder that the sect master has been subjected to.

If the sect master has a good deal because of this, he will be unable to escape the blame for his death.

"Boom!"

A purple thunderbolt tore through the clouds at once, and it slashed down towards Cao Fan's head at an extremely fast speed.
