Three months later, the forbidden place "Huangling Cave" on the top of Huangrifeng, Liu Yu was dressed in a plain robe, with a solemn expression and followed the master Zhang Yuanzhen into the stone cave, the cave is not big, about two zhang wide, filled with milky white fog, the concentration of the five elements of spiritual energy is high, and it has reached a state of atomization visible to the naked eye.

Liu Yu followed closely behind Zhang Yuanzhen, walking in the stone cave where the clouds and mist were fluttering like a fairyland, after hundreds of steps, the two turned into a side hole, and then passed through six or seven stone rooms, and came to the bottom of the side cave in front of the "Zhufu Stone Room", this "Zhufu Stone Room" is the closest to the heaven and earth spirit cave "Huang Lingquan" among more than ten stone rooms.

Recently, there are dozens of disciples in the sect who have registered to build the foundation, especially this "Zhufu Stone Room" is almost occupied by the disciples of the eight major families of the Zongmen, and the quota is scheduled to be scheduled for half a year.

"Yu'er, impact the bottleneck of the "Dan Heart Acupoint", open up the "Purple Mansion" is the foundation of the avenue, this step is extremely dangerous, and you build the foundation with the method of "Double Dan Quenching Field", you need to be more and more careful, do not rush it, and must be gradual and gradual. If you can't do anything, you need to know how to make trade-offs, and you must not gamble and lose your life, you know?" Zhang Yuanzhen brought Liu Yu to the stone door of the "Zhufu Stone Room", turned around and said sternly.

"Disciple knows!" Liu Yu bowed his hand and replied with a firm gaze.

"Well, Yu'er, you are resolute by nature, you know all this as a teacher, so I won't say more as a teacher, I wish you to open up the Purple Mansion as soon as possible and ascend to the path!" Zhang Yuanzhen took a deep breath, patted Liu Yu's shoulder, and said solemnly.

Zhang Yuanzhen saw his unusually firm eyes, and knew that Liu Yu did not listen to his words, as the saying goes: "Stay in the green mountains, don't be afraid of no firewood." But at this point, who can really make a trade-off?

After taking this step, you can really embark on the path of the Great Dao Immortal, but if you can't take this step, you are no different from a mortal in the world, after decades of penance, no one will give up easily, Zhang Yuanzhen has seen too many disciples of the sect who lost their lives in order to fight for a glimmer of opportunity.

So he didn't open his mouth to persuade Liu Yu, the authorities are confused, facing the first test of the way of heaven, he can only make his own choice, everything can only rely on himself, whether it is life or death, it is all in one thought, whether he can take this step, can only depend on the will of heaven.

"Thank you, Master, for your words!" Liu Yu bowed his head and bowed again.

"Let's go in!" Zhang Yuanzhen said with a light sigh, when Liu Yu turned around and walked into the stone room, Zhang Yuanzhen waved one hand, and the stone door of the mansion room fell to the ground with a bang, sealing the entrance, and the surface of the stone door floated with incantations and spiritual light, and the guard ban was automatically opened.

The "Zhufu Stone Room" was also filled with thick clouds and mist, Liu Yu walked to the center of the stone room and sat down, took a deep breath, calmed his nerves, and emptied all the distracting thoughts in his heart.

The "Yellow Spirit Heart-Breaking Array" set up in the stone room began to operate, the Dao Dao Array lit up, the spell floated in the air, and the surrounding mist-like aura quickly focused towards the center of the array, forming a milky white cloud, wrapping Liu Yu in it, making it impossible to see the reality in it.

After a pillar of incense, Liu Yu opened his eyes suddenly, first removed the thin Taoist robe on his body, and then took out four exquisite wooden boxes and a blood-colored jade bottle from the storage bag, and placed them on the ground directly in front of them along with the storage bags, respectively, two "Zhuji Dan", one "Heart-Breaking Pill", one "Jiaoying Pill", and a bottle of prepared "Quenching Spiritual Liquid".

Two "Zhuji Dan" were collected by Liu Yu when he went to Huangyuetang the day before yesterday, one was a reward issued by the sect, and one was exchanged by Liu Yu for 5,000 contribution points, "Heart-Breaking Pill" and "Jiaoying Pill" were refined by the ancestor Xuanmu Zhenren, and handed over to Liu Yu at the beginning of the month.

In addition to the "Three-clawed Jiaoying" essence blood and beast pill, several other precious spiritual materials are needed, such as thousand-year-old snow mushroom, thousand-year-old chalcedony, etc.

In fact, if Liu Yu didn't hand over the "Three-clawed Jiaoying" essence blood and beast pill, he would really not be able to gather these spiritual materials for refining the "Jiaoying Pill" in a short period of time.

Master Ancestor Xuanmu Zhenren only refined four finished pills this time, one each from the Xiahou family and the Huang family, and one was accepted by the sect master. The grain of Xiahou's family was given to Xiahou Wu, and half a month ago, Xiahou Wu had successfully advanced to build the foundation of the four mansions with this Dan.

After a while, the surface of Liu Yulu's skin in the clouds and mist condensed into droplets of liquid spiritual energy like "dewdrops", and when Liu Yu cast the "Yellow Spirit Breaking Heart Determination" that had been cultivated, the pores of his whole body opened, and he began to absorb the spiritual energy from the semi-liquid clouds around him at a rapid pace.

A large number of clouds and liquid spirit beads poured into the body from Liu Yu's pores, nostrils, ear holes and other parts of the body. It was then transported to the dantian through the meridians around the body, and the dantian expanded rapidly, and soon reached the limit that the dantian could accommodate.

At this time, a wooden box on the ground automatically opened, and a crimson "Zhuji Dan" floated from it, flew into Liu Yu's mouth, and slid down to the heart of the abdomen, and the surface of the elixir gradually liquefied, exuding a red medicinal power.

Liu Yu immediately controlled this medicinal power, introduced it into the dantian along the meridians, and merged with the vigorous spiritual power in the dantian to form a special spiritual power, blasting towards the Danxin acupoint in the middle of the dantian.

This special spiritual power, under the control of Liu Yu's spiritual sense, accurately hit the Dan Heart Acupoint. Suddenly, a strong anti-shock force was generated, spreading rapidly to the surroundings, and the inner wall of the dantian was instantly impacted by a strong shock wave.

However, the "Huang Ling Heart Breaking Array" combined with the "Huang Ling Heart Breaking Array" in the stone room had already formed a spiritual power barrier in front of the inner wall of Liu Yu's dantian, blocking and absorbing a concussive force.

As the melting of the "Zhuji Dan" accelerated, the impact of Liu Yu's spiritual power on the Dan Heart Acupoint became stronger and stronger, and the power of the anti-shock force was also getting stronger and stronger.

"Senior sister, do you say that Senior Brother can he succeed in building the foundation this time?" At this time, in a green bamboo room in Muyuan Courtyard, Tang Zhi held his head and asked Murong Yu who was sitting opposite worriedly.

"Senior Brother Liu, he has always been blessed, and he should be able to take this step. Murong Yu was silent for a moment and said comfortingly.

"Building the foundation" is the first test of the Heavenly Dao, who can say that there is 100% certainty of getting through, besides, Senior Brother Liu's qualifications are too mediocre, and it is even more difficult to take this step, Murong Yu is actually not very optimistic about Liu Yu, but he still comforted Tang Zhi against his will.

"I hope that the senior brother can be the same as the senior sister and successfully open up the "Purple Mansion". Tang Zhi took a deep breath and said, after her father was killed, her senior brother was still as good to her as before, Tang Zhi and Liu Yu were already like brothers and sisters, after Liu Yu followed his master to the "Huangling Cave", Tang Zhi's heart has been up and down.

"That's right, Zhi'er! How are your "Qi Reservoir Veins" dissolving, and when will you be sure to advance to the ninth level of Qi cultivation. "Murong Yu had completed the foundation building ten days ago, and now he was a monk of the three mansions of the foundation building, and he didn't know how to enlighten Tang Zhi for a while, so he changed the topic and asked about Tang Zhi's cultivation.

"Senior sister, don't laugh at me, there is still half of the "Qi Reservoir Vein" left, and it will take two years to say the least. Tang Zhi couldn't help but sigh deeply, he and his senior brother had the same spiritual root qualifications, and now that the senior brother had retreated to build a foundation, and his cultivation was only at the eighth level of qi cultivation, thinking about himself was really uncompromising.

Since she was a child, her father strictly urged her to meditate and cultivate, but at that time, she was willful and playful, and never took it too seriously, which always made her father angry.

Tang Zhi's eyes appeared in front of him, his eyes couldn't help but redden, and he said silently in his heart: "Dad, don't worry! Zhi'er will definitely practice hard in the future, advance to build a foundation, kill that pair of dog men and women, and avenge you." ”
