In the end, although Zheng Dong had many questions in his heart because of the issue of authority, under the telling of the prison spirit, he still roughly understood the function of this so-called first-order heaven and earth prison.

There are a total of four buildings in the first-order heaven and earth prison, which are the prison cell, the yafang, and the weapon room, and the building in front of Zheng Dong is the cell, which can imprison a creature that goes against the way of heaven, and refine and squeeze the energy of the creature, which can be used as the accumulation of prison promotion, and can be fed back to the official in charge of the prison, so that he has the ability to imprison some of the creatures.

As the name suggests, the yafang is a place for the yacha to rest, but this is not a simple rest, the yafang has the miraculous effect of assisting cultivation and treatment, the innate yaqi inside, just the first-order yafang, can increase the degree of cultivation and injury healing by three times, and each promotion to the first order will be increased by three times on the original basis, and other wonderful uses will be born when integrating the corresponding exotic treasure when advancing.

According to the different levels of the machinery room, some Heavenly Dao magic tools will be conjured up in it, and they will be used on those creatures who are disgusted by the Heavenly Dao, with all kinds of indescribable wonderful uses. It's a pity that except for the cell that evolved because of the imprisoning of the demon ape, the other two buildings had to be built by Zheng Dong himself.

The primary building only needs to provide an energy called Nightmare Yuan, the first-order machine room needs one hundred and fifty Nightmare Yuan, and the first-order government room needs three hundred Nightmare Yuan, as the building level increases, and then if you want to upgrade, in addition to the need for Nightmare Yuan, you must also provide a base treasure that meets the attributes, the higher the base treasure level, the more powerful the building function will be.

There are three basic ways to obtain the Yuan Yuan, one is the prisoner in the cell, the second is to sacrifice through the guò altar, and the third is to use merit points to make a one-to-one conversion.

The prisoners in the prison are currently only the six-eared demon ape, and because the level of the demon ape is too high, far beyond the range that the first-order prison can bear, so most of the demonic qi extracted from the demon ape is used to consolidate and support the cell, and there are very few that can be converted into a nightmare element, according to the answer given by the prison spirit, the current prison can only provide a little nightmare yuan every day, and it will take at least a year and a half to upgrade the two buildings with this energy alone.

Altar sacrifice, at present, Zheng Dong can count the sacrifice in his hand only the six-eared demon ape, and it is also a high-level sacrifice, the problem is that he is barely imprisoned by the prison cell, once it is released, let alone suppressing the other party on the altar for a minute, and completing the sacrifice ceremony, I am afraid that it will cost his life in seconds.

As for the merit value conversion, it is not within Zheng Dong's consideration, through guò to communicate with the prison spirit, Zheng Dong knows that the merit value is not only the universal currency in this space, but also related to the promotion of his level.

Zheng Dong is a very realistic person, knowing that there is no possibility of upgrading the building in the short term, he began to calculate the current capital in his hands, under the explanation of the prison spirit, he understands that good deeds are used to practice some Heavenly Dao exclusive skills, bad karma is used to manipulate weapons, and spiritual roots are necessary conditions for cultivating immortal Dao, normally speaking, people without spiritual roots cannot cultivate.

The most common spiritual root is the five elements of gold, wood, water, fire, and earth, plus thunder, poison, Ice, acid and other mutated spiritual roots, as well as the light and dark spiritual roots, according to different physiques, the total number of spiritual roots is also different, the full value of each spiritual root is one hundred, called the heavenly spiritual root, more than ninety less than one hundred is called the earth spiritual root, more than eighty is less than ninety is the true spiritual root, more than seventy is less than eighty is the upper grade spiritual root, more than sixty is less than seventy is the middle grade spiritual root, more than fifty is less than sixty is the lower grade spiritual root, everything below fifty is an inferior spiritual root, belongs to the kind of effort of a hundred times and little return.

Zheng Dong's body has all five elements of spiritual roots, among which the fire wood spiritual root is as high as eighty-five points, if there are corresponding matching exercises and resources, there is at least a thirty percent chance of being able to cultivate to the realm of real people, and the name of the true spiritual root is also derived from this.

Zheng Dong, who has been growing up in the market for eighteen years, suddenly came into contact with the fairy road, and the excitement in his heart can be imagined.

Zheng Dong walked out of the cell, and in front of the octagonal altar that he came, he knew that this altar was a passage to the outside world, and it was also an artifact-level building, as long as he had a suitable sacrifice, or a high enough merit value, he could basically get anything he wanted through guò.

With his hands pressed on the altar, Chen Dong prayed silently in his heart: "Heavenly Dao captures the third-class apprentice and begs for Heavenly Dao's mercy." ”

As the prayer ended, the eight-sided altar suddenly appeared with purple light, and an inexplicable force linked Zheng Dong's thoughts with the altar, and four more golden doors appeared in front of him with a shock in his mind, and the words "wealth, law, and land" were written on the doors.

Zheng Dong's attention was focused on the golden gate with the word wealth written, and suddenly the four golden doors disappeared, and there were four more silver doors in front of him, which were written on the doors, spirit stones, spirit medicines, spirit materials, and spirit treasures, as the mind came into contact with the silver gate with the spirit stone written, some information poured into his mind in an instant, and one hundred meritorious deeds could be exchanged for a high-grade spirit stone, a hundred medium-grade spirit stones, and ten thousand low-grade spirit stones.

As Zheng Dong's mind focused on the elixir silver gate, six kinds of elixirs appeared in his mind, Xiao Pei Yuan Dan exchanged ten pills for each merit value, taken during the Qi training period, and a small amount of conversion to enhance the true qi, and the ten merit values of the Great Pei Yuan Dan were exchanged for one pill, which could greatly enhance the true qi of qi training, and could also be used to break through the advanced barrier.

Wupin Detoxification Pill, which can solve all kinds of mundane poisons, each merit value is exchanged for a bottle, and there are fifty grains inside, and the inferior detoxification pill can be used to treat internal injuries with a grain of huàn per merit value, and each merit value is worth one bottle of Shengjisan, which can be used to treat external injuries, and Cao Huan Dan is worth one grain per merit and can be used to treat internal injuries.

Inside the spiritual material gate are some refining tools, alchemy, and array materials, with Zheng Dong's existing hundred merit value can be exchanged for hundreds of varieties, he simply took a look at it and withdrew, as for the Lingbao Gate, he simply couldn't push it open, he thought about it carefully and understood, the heaven and earth spirit treasure is a rare thing, it is estimated that the hundred merits he has, even the lowest level of the spirit treasure to exchange huàn requirements have not been met, so it is not open to him.

Exiting the Golden Gate of the word Cai, the Golden Gate printed with the word "Ludi", even if Zheng Dong's mind collided with it, it still could not be opened, which undoubtedly proved his previous inference, but he was not discouraged, after all, the most important thing for him at present was to get an immortal cultivation method as a stepping stone for him to embark on the immortal road.

The golden gate of the law word is also divided into four silver gates, which are exercises, techniques, formations, and runes, Zheng Dong directly linked his consciousness to the silver gate of the exercises, and instantly a huge library appeared in Zheng Dong's mind, and there were tens of thousands of jade slips in a dazzling array of them, but except for dozens of scattered faint light, most of the rest of the jade slips were gray, he tried to touch it, and his whole mind was bounced away, obviously not because he had few merits, or because of the level, those exercises were not open to him.

Zheng Dong browsed the jade slips with a glimmer of light in turn, and now except for a "Xuan Bing Duel" that is suitable for the cultivation of the ice spirit root, the rest of the exercises are all corresponding to the five elements spirit root attributes, and each line has six or seven kinds of exercises, what makes Zheng Dong frustrated is that these exercises are all a single cultivation system, and his fire wood is eighty-five points, and it is a pity in his opinion to give up that system.

Among the five elements, the gold system has the strongest single attack, the water system and the wood system are biased towards healing, the earth system focuses on defense, and the fire system is the most destructive, hesitated for a moment, and finally Zheng Dongyi gritted his teeth and chose the fire system exercises, he has always believed that the fist is the truth, and in his opinion, the treatment of the wood system can only be in an auxiliary position at most.

There are as many as eight fire exercises, without the guidance of the teacher, others may hesitate, Zheng Dong directly chose one of the "Six Yan True Fire Decisions", the reason why he chose this exercise is very simple, because among all the fire exercises, the "Six Yan True Fire Decisions" requires the highest merit value, eighty-five merit points, and most of the merit values required for the rest of the exercises are between thirty and fifty, the Heavenly Dao Altar is not a worldly profiteer, you get what you pay for, and the most expensive must be the best.

Immediately after Zheng Dong entered the elixir door again, he exchanged for twenty small Peiyuan pills, one each of the lower grade detoxification pill, Shengjisan, and grass return pill, and there were still ten merit points left for emergencies, after completing this qiē, Zheng Dong whispered: "Break" Under the shock of the divine soul, his soul instantly withdrew from the prison space of heaven and earth and returned to his body.

Zheng Dong's body was still lying in the crack of the ground, and a jade slip, three porcelain bottles and a brown pill appeared out of thin air beside him, indicating that the qiē he had just experienced was not illusory, and the dust raised in mid-air had not yet dissipated, and he felt that he had been in the prison of heaven and earth for at least half a day, and the outside time seemed to have just passed a minute.

He struggled to sit up, but with a slight movement, his internal organs seemed to be burning, a stream of purple-black dirty blood gushed out along his mouth and nose, and a violent cough accompanied by heart-rending pain, let Zheng Dong know that he had been hit hard under the pressure of demonic energy, and his internal organs were broken.

"How can the Xianjia pill be a little wonderful, even if one doesn't work, it's a big deal to exchange ten more pills, I don't believe that I can't cure my internal injury. Zheng Dong muttered to himself as he picked up the brown grass pill and put it in his mouth, just about to swallow it, but he didn't expect the grass pill to come into contact with the saliva in his mouth, and it immediately melted into a cold air current, sliding down his throat and flowing through his whole body.

The pain where the air flow passed disappeared in an instant, but the air flow dissipated between a few breaths, Zheng Dong jumped up from the crack in the ground, and suddenly felt that the whole body was comfortable, not only was the serious injury completely healed from death, but the whole person was in an unprecedentedly good state, Zheng Dong was immediately overjoyed, the grass returned to the pill so magical, doesn't it mean that as long as he has a breath in the future, he can instantly recover as before.

Zheng Dong, who lacked the necessary attempts, didn't know that the reason why the Cao Huan Dan had such a miraculous curative effect was related to his mortal body, if he entered the Qi training period, his body would be one hundred and ten times stronger under the nourishment of the aura and true qi, and the effectiveness of the Cao Huan Dan would be greatly reduced, and when it came to the foundation building period, this primary healing pill would be completely ineffective.
