Zhang Zhe saw that Ren Xiaoyao didn't have too many strange looks, thinking that Ren Xiaoyao knew about it, so he continued to spread the word: "In the Medicine God Sect, in addition to the sect tasks on the surface, many elders in the Dan stage and even elders in the Yuan Infant stage will issue some hidden sect tasks, and the hidden alchemy task is the other most common one. The ordinary hidden task is only to help people from other sects refine some ordinary pills and earn some spirit stones, and only ordinary disciples in the sect will accept them. However, the task of refining this hidden rare elixir is a high-level hidden task, referred to as the dark gold task, and it is not something that ordinary people can take. Since Senior Brother Ren dared to challenge Hua Ye, he must have attained a lot of alchemy, and now he happened to meet one of the few people who could issue hidden tasks, as long as Senior Brother Ren was interested, this dark gold task could be issued to Senior Brother Ren. ”

The words "Rare Dan Fang", "Ancient Dan Fang" and "Improved Dan Fang" deeply attracted Ren Xiaoyao.

Ren Xiaoyao got a large amount of elixir from the Qingyun space, and he was worried that there was no suitable pill to refine. Ordinary pills can be refined, but the effect of ordinary pills on cultivation cannot satisfy Ren Xiaoyao. Ren Xiaoyao has been paying attention to the news of some rare Dan Fang since the foundation was built.

Now that he encounters this hidden task, he can come into contact with the rare Dan Fang, how not to make Ren Yao excited. In fact, the task is secondary, and what Ren Xiaoyao is most concerned about is that by doing this hidden task, he can obtain a rare Dan recipe. In this way, Ren Xiaoyao would be able to refine a large number of rare pills.

However, Ren Xiaoyao has just experienced a catastrophe, and his vigilance is not ordinarily strong, and he still has some doubts about the benefits of this door-to-door delivery.

"There should be some restrictions and dangers in taking on these hidden missions!" Ren Xiaoyao asked in disbelief.

"Restrictions are there, of course, but there are no dangers. This restriction is also simple, there are no sect contribution points for hidden tasks, and the materials and Danfang are provided by me, and Senior Brother Ren is responsible for refining. You can only take one kind of alchemy task at a time, and hand over one furnace of elixir for every two furnaces of materials, and each furnace of elixir has to bet 10,000 lower grade spirit stones, and when the pill is returned, each furnace of pills will return 9,000 lower grade spirit stones. As for this danger, although the Rare Dan Fang is a treasure of the sect and is not allowed to circulate, there are also formal ways to obtain it. As long as you spend a million sect contribution points, you can go to the Tibetan Dan Pavilion to obtain a rare Dan recipe. However, one million sect contribution points are equivalent to one million lower grade spirit stones, and not all foundation building monks can afford it. There is a workaround here, and this workaround is to ask your master to teach you this pill. In this case, even if someone else finds out that you know this pill recipe, you can use the excuse that it was taught by your master. The Medicine God Sect does not restrict disciples from helping others refine pills to earn spirit stones, as long as you can prove that the source of your pill is legitimate, there is no danger. "Everyone who is new to hidden missions has a defensive mentality, and Zhang Zhe is used to it, so he explained the limitations and dangers in detail again.

After listening to this, Ren Xiaoyao pondered for a while, and felt that it was unlikely that there was a conspiracy in this.

"What is the maximum number of furnace tasks that can be taken at one time?" asked Ren Xiaoyao.

"You can take as many as you want, 1,000 furnaces, 10,000 furnaces, you can do it. However, the time limit for each mission is one year, and if you don't submit the mission within one year, the spirit stones will be confiscated, and you will forever lose the opportunity to take the hidden mission. Zhang Zhe saw that Ren Xiaoyao was already moved, his face was happy, and he added.

For every 10,000 lower grade spirit stones, 9,000 lower grade spirit stones will be returned, and the remaining 1,000 lower grade spirit stones, of which 500 will fall into Zhang Zhe's hands, which is one of the two major sources of spirit stones obtained by Zhang Zhe by issuing hidden tasks. Another source of spirit stones is naturally bribery like Ren Xiaoyao's previous one.

"I don't have so many spirit stones on me now, when I have enough spirit stones, I'll come back to take the task in a few days. Ren Xiaoyao made an excuse and did not immediately take on this hidden mission.

Many people who are new to hidden tasks also go to investigate first and then pick them up, which is not unusual, Zhang Zhe also understands and does not ask much.

After leaving the Hall of Merit, Ren Xiaoyao returned directly to Luochen Peak, and when Qiu Caizhang was in the cave mansion, he asked about the hidden mission.

Qiu Caizhang has been a Mixed Medicine God Sect for many years, so he is naturally clear about this matter, and even Qiu Caizhang has three rare pill formulas in his hand that are suitable for the use of foundation building monks, and they are all given to Ren Xiaoyao.

The three rare pills that Qiu Caizhang gave to Ren Xiaoyao were the Ning Yuan Pill that he had given to Ren Xiaoyao before, the improved Gathering Spirit Pill and the Huixin Pill that could make people smart. Ren Xiaoyao took these three kinds of Dan recipes and was overjoyed, because the materials used in these three Dan recipes were not rare, and Ren Xiaoyao had them, and they had a lot of them.

Leaving Luochen Peak, Ren Xiaoyao returned to the Hall of Merit again, handed over 100,000 spirit stones, and took over the refining task of ten furnaces of rare pills from Zhang Zhe. What was refined this time was the Yuan Ling Pill, which was an elixir that was beneficial to the cultivation of the foundation building cultivators, and it belonged to an improved elixir.

The main purpose of Ren Xiaoyao taking on the task of refining this pill was to obtain this pill. As for why he only received ten furnaces, firstly, Ren Xiaoyao still didn't trust this Zhang Zhe and didn't want to expose his net worth too much, and the other reason was that Ren Xiaoyao didn't have time for alchemy recently.

In addition to this hidden task, Ren Xiaoyao also took on the sect task of refining the Qi Refining Stage Pill of hundreds of furnaces in order to obtain contribution points. Ren Xiaoyao did this, in addition to obtaining contribution points, the main purpose was to paralyze Hua Ye of Du Tianfeng, making him think that he had not received the sect task in the foundation building period, but had to take the sect task in the qi refining period.

After leaving the Hall of Merit again, Ren Xiaoyao didn't go anywhere, and went directly back to his cave.

In the back mountain of the Medicine God Sect, Ren Xiaoyao returned to the cave mansion that he hadn't returned to for nearly nine years, with a wry smile on his face.

Where is this cave, it is simply a barren mountain, overgrown with weeds, if it weren't for Ren Xiaoyao to make some marks in advance, he wouldn't have been able to find the location of his cave. Moreover, judging from the marks left by Ren Yao before, this place has not been destroyed.

Ren Xiaoyao identified the direction, came to a small flat slope overgrown with weeds, dug a large pit more than two meters deep, and finally revealed a big hole. This hole was deliberately covered up by Xiaoyao nine years ago, because there was a fine spiritual eye fountain inside.

When he came to the bottom of the cave and saw that the spring of spiritual eyes was still there, Ren Xiaoyao's heart was at ease.

The immediate priority now is to build a decent cave house. Ren Xiaoyao left the cave, returned to the ground, identified the direction, and spent more than an hour laying down the Qianyuan Circulation Array, the general direction of the Spirit Eye Spring was the center of the Qianyuan Circulation Array.

The Qianyuan Circulation Array is a defensive array, which can be resisted for a while by connecting with the attacks of Monk Dan, and it is also the most powerful defensive array in Ren Xiaoyao's hands at present, so it will naturally be used to protect the cave.

After setting up the Qianyuan Circulation Array, Ren Xiaoyao took out the Ninety-Nine Eighty-One Array Instruments again, and was busy for more than three hours before he gave down a complete set of Ninety-Nine Gathering Spirit Array. The Ninety-Nine Gathering Spirit Array was laid out in the Qianyuan Circulation Array, and although the two did not have a combined effect, they did not interfere with each other.

As soon as the Ninety-Nine Gathering Spirit Array was set up, Ren Xiaoyao clearly felt that the aura in the air was slowly becoming richer, and the aura concentration was still slowly increasing.

After laying these out, Ren Xiaoyao shook the spirit beast bag and released Ren Bi'er, treasure hunting mouse Xiaobao and thin monkey Xiaohuang. As soon as Ren Bi'er was released, she complained to Ren Xiaoyao about the black queen in the spirit beast bag, and happily pulled Xiao Huang to play.

Ren Bi'er originally wanted to pull Xiaobao to play with her, but as soon as Xiaobao came out of the spirit beast bag, he recognized this place, squeaked excitedly, and immediately ran into the ground, and there was no mouse shadow. Ren Xiaoyao knew that this little treasure was extremely sensitive to treasures, and knew that there was a spiritual eye spring here, and now he must be soaking in that spiritual eye.

Ren Bier is simple, you can play anywhere. The Qianyuan Circulation Array and the Ninety-Nine Spirit Gathering Array under Ren Xiaoyao are not very spacey, and they can see Ren Bi'er at any time, and Ren Xiaoyao is relieved to let her play by herself.

Next, Ren Xiaoyao began to arrange the cave mansion. Although Ren Xiaoyao doesn't care, the cave mansion must have the appearance of a cave mansion after all. To the east, Ren Xiaoyao carved out several large medicine gardens and sowed some ordinary elixir seeds. In the middle of the Qianyuan Circulation Array, Ren Xiaoyao used some simple earth-based spells, combined with some ordinary wood in the storage bag, to build an ordinary house of more than 300 square meters.

In this house, there is an alchemy room, a cultivation room, a utility room, a kitchen, a bedroom, and so on. Although each room seems to be empty, as far as the whole house is concerned, it is finally functional.

When building the house, Ren Bier also helped on the side, but Ren Bier didn't even have the strength to move a brick, all she could do was that I liked that there was a tree here, I liked that the house was bigger, and I liked to open a window here.

Many of the facilities in the room are actually unnecessary, but because Ren Bier likes it, Ren Xiaoyao is also happy to change and add them.

Of course, Ren Xiaoyao naturally knew that the house was just an ornament, and the most important role of the house was to cover up the fountain of spiritual eyes. Underneath the entire house, where the Spirit Eye Spring had been, Ren Xiaoyao had opened up a huge space dedicated to cultivation and alchemy. And in this space, Ren Xiaoyao alone laid down a spirit detention array and several concealment formations.

Near the Spring of the Spirit Eye, with the storage of this Detention Spirit Array, plus the Ninety-Nine Gathering Spirit Array outside, the concentration of spiritual energy here is three or four times richer than that of the high-grade spiritual vein.

The exit of this secret cultivation place is in the utility room full of miscellaneous items, and the cultivation room and alchemy room are close to the ground, so if something really happens, you can quickly return to the ground.

After the cave was built, a day had passed. According to Ren Xiaoyao's thoughts, he should go into retreat immediately. But now that she is in Ren Bi'er, Ren Xiaoyao has to take care of Ren Bi'er.

It took another day for Ren Xiaoyao to go outside the cave, catch hundreds of ordinary rabbits and birds, and encircle them in the magic circle. At the same time, more than 100 flowers and trees transplanted by Ren Xiaoyao arranged the cave mansion into a place similar to the Valley of Love Flowers. With these animals, flowers and trees, plus Xiao Huang and Xiao Bao to accompany them, presumably the simple Ren Bier will not be lonely.

Ren Xiaoyao also tried to teach Ren Bi'er to cultivate, but Ren Bi'er didn't know how to cultivate at all, nor did she know how to operate mana. The only spell she knows now is the flame technique, and it will be inexplicable to watch others cast fireballs.

Later, Ren Xiaoyao tried Ren Bi'er again, and found that Ren Bi'er couldn't even have the special ability of "throwing stones" before. Ren Xiaoyao estimated that this Ren Bi'er had to be in an abnormal situation before she could hit others with a stone.

It seems that this Ren Bi'er's cultivation method is also different from others, and she needs to see more spells cast with her own eyes before she can comprehend certain spells. But here, Ren Xiaoyao didn't have time to demonstrate Ren Bi'er's spells over and over again. If Ren Bi'er is allowed to watch Ren Xiaoyao cultivate on the side, and then realize it by herself, it is estimated that Ren Bi'er can't bear to be lonely.

In this case, Ren Xiaoyao really can't teach Ren Bi'er, but fortunately, Ren Bi'er can use storage bags. Ren Xiaoyao had to take out a storage bag alone, put a large amount of the Gathering Spirit Pill that Li Xiaohong had refined before, and hang a rope around Ren Bi'er's waist, so that Ren Bi'er could eat and play when she was fine.

After about a day, Senior Brother Fu Ziheng came to Ren Xiaoyao's cave mansion, handed over the alchemy experience collected by Qiu Caizhang to Ren Xiaoyao, and talked with Ren Xiaoyao.

Originally, Fu Ziheng wanted to invite Ren Xiaoyao to get together with several of their senior brothers, but when he saw the pale color on Ren Xiaoyao's face, he had to give up.

"Fifth Senior Brother, your cave mansion is very distinctively arranged. However, there is something that the senior brother must say, immortal cultivators must not indulge in external objects, otherwise it will be harmful and useless. Before leaving, Fu Ziheng said earnestly.

"Senior brother knows, Senior Brother Xie has good words. Ren Xiaoyao naturally didn't explain anything, but the sincere persuasion of the senior brother is still worthy of Ren Xiaoyao's thanks.

After sending off his senior brother Fu Ziheng, Ren Xiaoyao stimulated the Qianyuan Circulation Array and the Ninety-Nine Gathering Spirit Array, stabilized his mind, and officially began the retreat.
