After that, while sending people to block the news, hoping to hide from the cultivation forces in the nearby states as they did last time the vault was opened, the eight major factions sent different numbers of disciples to explore in batches according to the progress of the vault opening, and they all accumulated their own strength, and concentrated on the elite disciples of the Dan period to give special care and training, hoping that these people could contribute to the exploration of the inner mansion after the vault was fully opened.

Although the news of the Xuantian Secret Treasure was closely guarded by the eight major factions in Xuanhe Prefecture, it eventually spread inadvertently, and soon reached the ears of many cultivation forces in nearby states, which naturally triggered the covetousness of these cultivation forces, and they began to secretly unite to exert strong pressure on the eight major factions.

However, the eight major factions were led by Tianyi Zhenren of Tianyi Sect, united with the Qingli Fairy of the Bishui Sect, and several Taishang elders of the remaining factions, and they failed to let the foreign sects get much benefit without showing weakness to the outside world.

The foreign forces were intimidated by the prestige of the existence of Tianyi Zhenren, and they did not dare to easily break out in the territory of the eight major factions that had been operating for many years, and finally bargained and reached an agreement under compromise, that is, the sects in the foreign sects with similar strength to the first four factions of the eight major factions could exchange some rare resources for a small part of the Xuantian Crystal to bring people into the secret vault through trading, and send people to hunt for treasures, and each faction could only send three people to participate after the cave treasure was fully opened, of course, if these sects could find the Xuantian Crystal by themselves, the eight major factions would also let it go。

At this point, the matter of the Xuantian Secret Vault, which had been in an uproar in the outside world, had finally come to an end, and as time passed, the Secret Vault gradually deepened to the extent of opening, and the Eight Great Sects also slowly sent more people into the outer areas, during which they could occasionally find some valuable treasures.

At this time, He Lingfeng didn't know anything about this, since he returned to the sect after participating in the Blue Meeting, he plunged into the secret room to retreat and do penance. And the last time he went out of the customs was a year after the middle stage of advancing to the foundation building, at that time, he only came out to make a slight adjustment, and after consulting a few problems in cultivation with his master, he entered the state of retreat again, and although Wang Fugui felt that He Lingfeng would be able to cultivate the Dan in a few years, he also did not think that He Lingfeng could achieve it when the Xuantian Secret Treasure was fully opened, so in order not to let it be distracted and affect his state of mind, he did not inform the secret treasure of the current world.

Time flies, spring goes to autumn, and it is another year in the blink of an eye.

Just when He Lingfeng was hurrying to cultivate and refining the five-colored spirit stone that the master had exchanged for him in order to get the pill as soon as possible, Feng Wuchen actually visited the Wanhua Immortal Sect one day, and also brought a secret letter from Tianyi Zhenren to He Lingfeng and a few things sealed in a brocade box.

Feng Wuchen heard that He Lingfeng was still in retreat and cultivating, although he really wanted to meet this little brother, he still pressed it down, and did not bother, and hurriedly left these few things for his master to hand over on his behalf, and then said goodbye and returned to the sect, looking very busy.

After more than a month, He Lingfeng went out again, this time, his cultivation had already reached the late stage of foundation building, it seemed that this five-colored spirit stone had a great effect on his cultivation of the cultivator of the five elements spirit root. He first went to meet his master, and by the way, he asked him a few questions in his follow-up cultivation, and He Lingfeng got a few things from Tianyi Zhenren from his master.

Back at the residence, He Lingfeng didn't take apart the other things in a hurry to look at them, but first picked up the jade slip secret letter and probed into it to check it, but only read the first few sentences before his expression changed, and he paused slightly before continuing to look at it with a surprised and solemn expression, and his expression changed several times in the process.

After a long time like this, He Lingfeng waved his hand and popped out a large fireball of beans with a cloudy face, which instantly adhered to the jade slip engraved with the secret letter, and then burst out with a "bang" A cloud of crimson flames destroyed it without leaving the slightest trace.

Only then did he let out a sigh of relief, looked at the brocade boxes, and after opening them one by one, he saw that they were all as mentioned in the letter, several pills to enhance the cultivation of monks in the foundation building period, as well as a small bottle of Shenyu liquid that would help to form pills, and then casually put them into the storage bag pinned to his waist. And this Yellow Rank Seven-Rank storage bag was also given to him by the master that day along with the pile of five-colored spirit stones, otherwise it would be really difficult for him to carry such a large number of things with him.

Then He Lingfeng paced back and forth in the hall, his brows furrowed, as if he was thinking about something important, and only stopped after almost a cup of tea, and sat back on the chair in the room, although his eyebrows were not fully stretched, but his expression had turned calm, and there was still a faint look of expectation, as if he had made up his mind.

"It seems that it is necessary to speed up the progress of cultivation, and it is necessary to reach the realm of Yudan......" He Lingfeng said in a low voice with a determined look in his eyes.

So, in the next few days, He Lingfeng asked his master for some questions that needed to be paid attention to, but Wang Fugui's master was a single spiritual root of the earth attribute, and monks with different attributes of the spiritual root would also encounter different problems, so in addition to this attribute, Wang Fugui could not guide He Lingfeng, a disciple with five attributes, on the matter of the elixir. As for the monks of the Five Elements Spiritual Root, the process of attaining the Dan is slightly different from that of ordinary multi-Spiritual Root monks.

However, fortunately, the matter of advanced knotting in the foundation building period is considered to be the category of low-level monks in the Tianhua cultivation realm, and it is not a secret thing, and many classics that guide the monk's cultivation path have records of their experiences and coping methods in this regard, and the inheritance hall in the sect happens to have these contents in three or four books. Therefore, He Lingfeng soaked in the Inheritance Hall and consulted for a few days in succession, and finally found some content worthy of reference and reference, and finally felt that everything was ready.

After He Lingfeng explained to his master that he was going to attack the realm of the Death Barrier this time, he hurriedly returned and walked into the secret room without hesitation.

The cold comes and the summer comes, the cicadas chirp and the leaves fall, the four seasons turn several times, and two and a half years have passed in the blink of an eye.

At noon on this day, He Lingfeng, who was sitting quietly in the secret room with his eyes closed, suddenly had an aura coming out of his body, and the red, gold, yellow, green, and blue five colors of spiritual light flashed alternately, repeating the cycle, looking extremely mysterious. He Lingfeng, who was the person concerned, was not surprised by this, but his hands quickly pinched the trick, and with his movements, the five-colored spiritual light flashed faster and faster, and finally after a while, after reaching a certain peak in its flickering frequency, the brilliance suddenly disappeared and fell silent.

And He Lingfeng, who had been nervously casting spells, finally exhaled a pale white turbidity and slowly opened his eyes, but saw that there were also five-colored spiritual lights flickering in the two black pupils, which were the same as before, but this time, after only a moment, they were completely hidden, and there was no abnormality in the slightest, and his eyes also returned to their former clarity. But his whole person seems to be very different from before the retreat, not only does his skin look much more delicate and moisturized, but his complexion is also a little whiter again, and even his body has a faint sense of indifference that does not eat the fireworks of the world.

This change was naturally brought about by He Lingfeng's successful advancement to the Dan Formation Period.

As early as half a month ago, He Lingfeng had cultivated all the exercises of the Five Elements Attributes to the peak of the late stage of foundation building, and the Five Elements Spiritual Liquid refined at the bottom of the dantian space was also in a saturated state over time. Therefore, after resting for three days, He Lingfeng spent two days very carefully adjusting his physical and mental state to the best, and only then did he take out the Juyuan Pill obtained at the Qinglan Meeting and the Shenyu liquid sent by Tianyi Zhenren and take it one after another, and after the medicinal power was completely refined, he began to carefully impact the realm of Jiedan.

However, the secret method of condensing Dan and the secret method of turning Dan used this time were a set of methods that He Lingfeng pondered after consulting many classics, referring to the secret method of knotting Dan in the "Five Elements True Sutra", and then combining it with the secret method in the five Five Elements Exercises he practiced.

He condensed all the five elements spiritual liquid in the dantian space into a solid state, and then calcined and refined it with the dantian true fire, and only after three full days did he condense it into a five-color pill slightly larger than his thumb, and then fused the seed of the dantian true fire into it before he could be considered a successful pill.
