Mortal cultivation of immortals is divided into several stages, namely: Qi refining, foundation building, enlightenment, fusion, heartbeat, Jindan, Yuanying, out-of-body, distraction, merger, cave void, Mahayana and tribulation.

After crossing the thunder tribulation, you can achieve positive results and soar in the day!

Building a foundation, as the name suggests, is the foundation of the avenue, and it is a hurdle to truly enter the right path of cultivating immortals, and its importance is naturally self-evident.

Originally, it would take Shen Ling nearly two months to build a foundation, but with the assistance of the Phantom Spirit Bead, his cultivation speed increased by five or six times, and with the addition of refining the full copy of the Quenching God Sword Sutra, he was about to build a foundation!

That is, in the blink of an eye, the spiritual power in the dantian was agitated and launched an impact on the meridians of the whole body!

Each impact brought Shen Ling a huge sense of pain, and it became more and more intense, and the whole person was as unbearable as if he had been torn repeatedly!

Shen Ling couldn't help but be secretly surprised, and a cold sweat broke out.

The Heavenly Illusion Sect also has many disciples to build a foundation, but no one has suffered like him, what's going on?

No matter what, the most urgent thing at the moment is to get through this difficulty!

Shen Ling's mind was still sober at the moment, and after he stood up with difficulty, he looked at Xu Kun solemnly:

"Kunzi, I'm going to start building the foundation, you stay here, don't let the idlers wait in."

"What? Building a foundation? Xu Kun was stunned for a moment, and immediately showed a happy expression, "Cousin, congratulations..."

Shen Ling gritted his teeth in pain, "Don't gossip too much... How many spirit stones do you still have? ”

"There are also thirty medium-grade spirit stones and fifty low-grade spirit stones."

Xu Kun hurriedly took out a bag and handed it to his cousin.

"With my eighty medium-grade spirit stones, it should be enough, right?"

"Cousin, why do you want so many spirit stones?"

"Of course, it's a spirit gathering array..."

The Spirit Gathering Array is a formation that is driven by spirit stones, and is mainly used to supplement the spiritual power of immortal cultivators. Generally speaking, it will not take too much spiritual power when building the foundation, unless the immortal cultivator himself has some kind of "birth defect", which causes the spiritual power to recover too slowly, not enough to achieve the strength of reshaping the physical body and meridians.

Of course, Shen Ling didn't have this kind of "birth defect", the reason why he wanted to set up the Spirit Formation was entirely because the spiritual power in the dantian was rapidly depleting and was about to be exhausted!

Once the dantian is exhausted, not only will it fall short, but the spiritual power will instantly backfire, the light dantian will be abolished, and the heavy one will explode and die!

Shen Ling didn't have time to figure out the reason why his spiritual power was consumed too quickly, and if he delayed it any longer, I was afraid that his life would be confessed!

"When I'm building a foundation, don't let outsiders disturb me." As he spoke, he divided the spirit stone into several parts and arranged them in a formation on the spot.

"If it were Master..."

"Master, it's even worse, I don't want him to worry about it."

As he spoke, Shen Ling sat in the eye of the Spirit Gathering Array, and the aura was slightly drawn, and pure spiritual power began to stir out from the inside of the spirit stone and drill into his body.

The spiritual power in the dantian was replenished in time, and Shen Ling felt a little better.

However, the meridians of the whole body are still suffering from constant impact, and there is no sign of the formation of "immortal embryos" in the dantian, which is far from enough to break through the qi refining period and build a foundation.

At this time, Shen Ling's mind had already settled, and his spiritual sense had shrunk to a point, no matter what happened in the outside world, he would be "indifferent".

Seeing that his cousin had already entered the state, Xu Kun didn't dare to be sloppy in the slightest, and stood aside nervously, waiting quietly.

An hour passed.

The Spirit Gathering Array dimmed, and the spirit source contained in the spirit stone was about to be exhausted.

Shen Ling actually hasn't broken through yet!

Xu Kun was so anxious that he scratched his ears and cheeks, pacing back and forth, not knowing what to do.

"Go and ask Master? But my cousin told me in advance not to disturb Master... Alas, it's over, it's over, it's hard for my cousin to be... Going to die on the foundation? ”

When Xu Kun thought of this, he couldn't help but feel sad, and slammed his chest.

At this time, someone outside the courtyard gate shouted:

"Big brother, I'm here to bring you wine!"

"It's... Is it a skinny monkey? ”

Xu Kun was stunned for a moment, secretly thinking that Li Chengfeng had already bowed to the two of him, and he was definitely not an "outsider", so he hurriedly opened the courtyard door.

"Big man?" Li Chengfeng carried the wine jar and said with a smile, "It's really time for you to come and drink two cups together?" ”

"What to drink... Hurry up and let me in! ”

Xu Kun grabbed Li Chengfeng's collar and dragged it over, and then flew up and closed the door.

Li Cheng took the risk of falling, and was about to turn around and scold him, but when he looked up, he saw his eldest brother Shen Ling meditating in the courtyard, and there was a circle of spirit gathering arrays around him that shone with a dim light.

"Big brother in... Building a foundation? Li Chengfeng was surprised.

Xu Kun sighed, "It's been built for more than an hour, and the Spirit Gathering Array is about to fail, cousin, he is more than lucky!" ”

"Is it so hard to build a foundation?"

Although Li Chengfeng has not built a foundation, he has been in Qianji Palace for a long time, and he has never eaten pork and seen pigs run.

For ordinary immortal cultivators, foundation building is far less terrifying, and everything is a matter of course.

Besides, the eldest brother's sword cultivation talent is there, and there can't be any accidents...

"Don't be stunned, think of a way?" Xu Kun urged.

Li Chengfeng put down the wine jar, hurriedly approached Shen Ling, and after taking a closer look, his eyes fixed on the Spirit Gathering Array.

"Big brother's breath is very stable, it doesn't seem like he has encountered any bottleneck, the problem is in these spirit stones..."Li Chengfeng said with his chin propped up.

"Impossible, these spirit stones are all given by the sect, there will be no problem..."

"There is no problem with the spirit stone itself, but you see, the spirit source inside is about to be consumed, and some more will have to be replaced. The foundation built by the eldest brother must be extraordinary, and a huge amount of spiritual source is needed, and the medium-grade spirit stone is still a little hot, so it is best to have some high-grade goods. ”

Xu Kun was embarrassed:

"Top-grade spirit stones? Don't say it's me, even my cousin doesn't have half a piece of it! ”

"I have ten yuan here, and I'll use it for my eldest brother first."

"What, you... You have? ”

Li Chengfeng took out ten high-grade spirit stones and carefully added them to the Spirit Gathering Array. It is worthy of being a top-grade spirit stone, the purity of the spirit source is ten times higher than that of the medium-grade, and the entire spirit gathering array has been resurrected with full blood.

"These ten spirit stones were given by the master, and they are usually of little use, they are all dusty, I can't imagine that I can help my eldest brother today..."

"Skinny monkey, you're so interesting, I finally didn't make friends with your brother in vain!"

Xu Kun showed gratitude.

The price of a high-grade spirit stone is equivalent to fifty times that of a medium-grade spirit stone, so it's no wonder that he will be impressed by Li Chengfeng.

"As long as the eldest brother is safe and sound..."Li Chengfeng said with a serious expression.

The two of them quietly guarded Shen Ling, and before they knew it, it was getting late, and the lone star was shining.

Those ten high-grade spirit stones actually gradually dimmed!

"It's evil!" Li Chengfeng's eyes widened, "Ten high-grade spirit stones are not enough for the eldest brother to build a foundation?" He... What the hell is he building? ”

"Brother Chengfeng, do you still have spirit stones on you?" Xu Kun sneered.

"It's gone... I can also get my hands on those belongings, and the rest of the spirit stones are all middle and lower grades, which is not enough time to insist on a stick of incense, if it really can't work, I can only ask for help from the master and uncle..."

"No, my cousin told me that I don't want to bother my master."

"It's... The eldest brother's temper is also quite stubborn, if he knows that we begged the master and them, he will definitely not be able to spare you and me. ”

Li Chengfeng looked distressed and shook his head slowly.

Suddenly, his eyes lit up!

"Why don't you try your luck in the Medicine King Palace?"
