In terms of age, Xu Dong is Chinese New Year's Eve one and a half years old today, and it is not too late to start practicing Bigu Gong from now on.

In the cultivation world, some people start to open valleys from the age of ten or twenty, some people do not open valleys until they are fifty or sixty years old, and some people do not open valleys for the rest of their lives.

From the perspective of the cultivation realm, he has already practiced to the middle stage of the Yuanying Realm, and he is about to break through the bottleneck of the sixth level of the Yuanying Realm, and it is indeed a bit late to start Bigu at this time.

There are many people who have already opened the valley when they are still in the mortal realm, and most cultivators choose to open the valley in the foundation building realm, and the reason why Xu Dong did not start to open the valley until the Yuanying realm is mainly related to his thundercloud spiritual root.

As a Thundercloud Spiritual Root Cultivator, his cultivation trajectory was extraordinary, and if the resources in all aspects were sufficient, his cultivation speed would be tenfold, dozens or even hundreds of times faster than that of an ordinary Spiritual Root Cultivator.

For example, for an ordinary spiritual root cultivator to practice to the middle stage of the Yuan Infant Realm, it would take at least one hundred and fifty years to practice, and as for those cultivators with miscellaneous spiritual roots and those without spiritual roots, it was even more difficult to imagine how long it would take.

The reason why a cultivator wants to open the valley is over-exaggerated in some cultivation classics, in fact, the main reason is that it is conducive to cultivation, and a practitioner needs a long retreat in order to break through the bottleneck, and it is obviously much more convenient after the valley is opened.

Because Thundercloud Spirit Root cultivators practice almost without bottlenecks, and it is rare for them to retreat for several days without eating or drinking, it is undoubtedly not so important for these practitioners with special roots and bones to cultivate in the early stage.

According to the cultivation system of the "Lotus 'Flower' and 'Cave' Immortal Records", the practice is divided into nine realms: mortal womb, foundation building, knotting, primordial infant, distraction, out-of-body, merger, Dacheng, and tribulation, and each realm is divided into nine realms.

These nine-layer realms are divided into three stages according to the stages: upper, middle and lower, the next stage is the five-step ladder of mortal fetus, foundation building, knotting, Yuanying and distraction; in the middle stage, there are three steps of out-of-body, merging and Dacheng; in the upper stage, there is only one step of crossing the tribulation.

Cultivation is like this, the more you cultivate to the high-level ladder, the more difficult it is to cultivate, and this is no exception for practitioners with special root bones, but these innate nobles are a little later than ordinary spiritual root cultivators.

Now, since the Holy Infant proposed to ask Xu Dong to practice the Bigu Gong, it was actually equivalent to giving him a signal that in his upcoming cultivation career, there must be a time when he needed to retreat and cultivate for a long time.

Before Xu Dong entered the underground dark room to practice Bigu Gong, he had to make some necessary preparations, such as receiving various pills from the royal treasury, as well as some other necessary cultivation materials.

He brought pots and shovels to the treasury to find Guo Yan, Guo Yan was busy allocating a batch of military materials to the Ministry of War, what tents, weapons, money and food, he was very busy, but no matter how big his head was, he didn't dare to snub the emperor.

"Your Majesty, you are here in person, yo ho, there are two fathers-in-law of pots and pots and shovels, and the old minister is here to ask the emperor for peace. ”

Guo Yi took his subordinates to bow to Xu Dongxing, but Xu Dongyi waved his hand to stop him, "Guo Aiqing, these etiquettes are waived, you quickly open the warehouse where the pill 'medicine' is stored for me, I want to see if there is anything needed." ”

"Your Majesty, you also know that some of the more valuable finished pills are in the underground treasure house, how can there be any good things in this big warehouse, I might as well take the emperor directly to the underground treasure house to find it." ”

Xu Dong noticed that Guo Yan's eyes flickered a little when he spoke, as if he was deliberately hiding something, Xu Dong felt strange, Guo Yan was hiding something as a manager of the general affairs office of the palace.

"Guo Aiqing, you don't know that when a monk chooses cultivation materials, he doesn't always use those good ones, and sometimes he will also choose some low-level spiritual 'pills' and pills. ”

Guo Yan hurriedly said, "I know, I know that I am too familiar with the habits of the previous emperors, and they have never received these low-level pills in the warehouse. ”

Xu Dong said, "I don't mean that I have to use those low-level spiritual 'medicines', but I just look in the treasury to see if there are a few things that I can see, if there are none, it's just that." ”

Since Xu Dong said this, Guo Tong couldn't say anything more, how could a courtier not even listen to the master's words, he had to lead Xu Dong towards the treasury.

Xu Dong followed Guo Tong to the deepest part of the warehouse, and saw a warehouse 'door' with "No. 637, broad beans" written on it, he couldn't help but smile, and used the warehouse with "broad beans" written to store the pills, which itself had a kind of cold humor.

The last time he went into the treasury to receive the spiritual 'medicine', he saw that the 'cocoon' on the 'door' was actually stored in the warehouse, and Guo Tong said that the main reason for doing this was to prevent the people in charge of the treasury from stealing it.

In fact, any of the barns in which such substances were stored were recorded in a booklet, on which the contents of the barn were registered one by one according to the number of the barn.

If you don't look at this booklet, even insiders won't know which barn is in which barn, or even which barn is empty and which is not, so it's not easy to steal.

And this pamphlet is only in the hands of the officials in charge of the treasury, that is to say, only in the hands of Guo Tong and another deputy director of the general affairs office, and only the two of them know the storage situation in the treasury.

Guo Tong used the key to open the lock on the 'door' of the warehouse, pushed open the heavy 'door' of the warehouse, and a strange smell came to his nose, Xu Dong shrunk his nose, and recognized that this was the smell of the pill' after mildew.

He walked in and looked at the goods stored on the shelves, sure enough, they were some middle and low-grade pills, but these pills had already been moldy, he took one in his hand and took a closer look, it turned out to be a waste pill that had been practiced.

"Hey, how is it a waste pill. Xu Dong was puzzled, "Guo Aiqing, how can there be a waste pill that you have put into the treasury, don't you even recognize the waste pill?" ”

Guo Yan's face changed, "Your Majesty, I'm ...... I ......"

Xu Dong calmly did not squeak, and inspected all the goods on several rows of shelves, and to his surprise, all the waste pills stored on these shelves were there, and there was hardly a genuine pill

This also found the reason why the pill is moldy, according to common sense, the genuine pill will not be moldy, only those discarded pills that lack heat due to the lack of production techniques are easy to mold.

"Guo Aiqing, what's going on, why is it all waste pills in the royal treasury. ”

"Your Majesty, I'm ...... I ......"

Seeing that Guo Tong couldn't answer for a long time, Xu Dong quickly understood a little in his heart, obviously he could rule out the possibility that someone entered the warehouse to secretly change 'sex', and the biggest possibility was that Guo Yan himself did something inside.

Now it can be guessed that it was Guo Yan himself who stole the beams and changed the pillars, and exchanged the genuine pills in the treasury with the waste pills, maybe he took these genuine pills to the market and sold them, and maybe there would be other uses.

Xu Dong asked sharply, "Guo Yan, you tell the truth, did you do this, where did you 'go' those genuine pills, and why did you do this." ”

Guo Yan's face turned from white to black, and then from black to white, "Emperor...... Your Majesty, Old ...... Old minister......"

"Guo Yan, you don't want to tell the truth, do you, I have my own way to make you speak, you just wait. Xu Dong threw down a sentence at Guo Yan, and walked towards the 'door' of the warehouse angrily.

Seeing Xu Dong's angry face, the pot and shovel asked anxiously, "Your Majesty, what's wrong with you, who made you angry, and what happened." ”

Xu Dong issued an order to the guards outside the 'gate', "You go into the warehouse and arrest Guo Yan, he has committed a capital crime, you must take good care of him, don't let him escape." More than a dozen guards listened to the emperor's order and rushed into the treasury like a whirlwind.

"Pots, shovels, and shovels, you go to the Ministry of Justice, the Ministry of Officials, and the Ministry of Rites respectively, and let Xu Li, the secretary of the Ministry of Officials, take charge of the three-hall trial, and there is a big cat behind Guo Yan's case, let Xu Li dig it out for me. ”

After such a major event as Guo Yan, Xu Dong originally wanted to personally supervise the trial of the three halls, but the matter of practicing Bigu Gong was tight, so he left the royal treasury and came to the "Hua'jing' Palace" located at the southern end of Chunyang Palace.

He walked into the "Essence Hall" with heavy steps, walked through the secret passage to find the entrance to the underground treasure house, took out the golden key from the treasure bag, and opened the heavy golden lock hanging on the "door" of the stone vault.

"Squeak. With a bang, he pushed open the two heavy stone 'doors', and walked into the underground treasure house, where several chests made of pure gold were placed against the wall, and these cabinets emitted a dull golden light.

These cabinets were all stuffed with cultivation items, one of them was stacked with exercise cheats, one cabinet was filled with magic tools, another cabinet was filled with formation tools, and another cabinet was full of talisman making tools.

Xu Dong's gaze fell on the innermost row of cabinets, because this cabinet contained high-grade pills, and his intention to come to the underground treasure house in a hurry was to find the pills he used when he was in Bigu.

These pills are not scattered like in the treasury, but are placed in the cabinet in an orderly manner in a 'jade' box, Xu Dong picked up a 'jade' box and looked at it, only to see the words "Bigu Dan" written on the lid of the box.

Seeing this box full of Bigu Dan, the 'yin' clouds on his face gradually dissipated, and the depression that had arisen just now because of Guo Yan was suddenly squeezed out of his 'chest' cavity, because he found what he wanted without much effort.

He had seen in a book dedicated to explaining Bigu that if you want to practice Bigu Gong, you must use Bigu Dan, and the cost of refining Bigu Dan is extremely expensive, and several of the top spiritual 'medicines' will not be found in the market.

The last time he refined the "Nourishing Soul Pill and Tranquility Pill", it was because he couldn't get the three flavors of the top spiritual 'medicine' and took a lot of pains, he was afraid that Lian Bigu Dan would follow in the footsteps of the last time, and now this box of Bigu Dan was in his hand, which was equivalent to letting him eat the reassuring pill.

He picked up two boxes of pills, one of which read "Qianxun Transformation Treasure", and the other box said "Sangong Pill", he didn't know what two pills were these two, and he had never heard of the names of these pills.

Just as he was about to put these two boxes of pills back on the shelf, a voice sounded in his heart, "Bring them with you, these two boxes of pills are very useful to you, and you will need them when you practice Bigu Gong." ”

The Holy Child did not appear, but spoke in the original body of the ambergris, "This box of 'Scattered Gong Pills' can disperse your exercises in a short period of time, and the 'Thousand Hiro Transformation Treasure' can quickly retrieve your exercises." ”
