The two of them studied for a month before they designed a set of formations with a time difference of ten years, but it was only theoretical, if this array was to be put into use, in addition to the spirit stone, a magic weapon was needed.

This magic weapon is called "retrospective clock", this clock will be used as the eye of the array, buried in the center of the circle, will not be affected by the time in the circle, and keep synchronized with the time of the outside world, the eye of the heavenly way will only capture the retrospective clock, and will not find the time change in the circle, so as to avoid the rules of the heavenly way.

Tian Xiang'er was responsible for drawing the formation diagram and practicing the formation, and Bai Xiaoxiao was responsible for going to Fang City to find the retrospective clock.

It took another two months for the two of them to work together to successfully build the entire time array.

Tian Xiang'er personally arranged this set of magic circles in the space medicine field, and then wrote down the growth of various medicinal materials one by one.

When he entered the space again the next day, all the herbs he had planted three months ago had matured overnight! Moreover, the years were all more than ten years, Tian Xiang'er was simply crazy with joy, picked up Qiqi, who was sleeping, and kissed him a few times: "Qiqi, we have made a fortune!"

Tian Xiang'er divided the mature medicinal materials into two parts, one part was used for Senior Sister Bai to make alchemy, and the other part continued to grow in the medicine field, and when the year reached a hundred years, it was immediately packaged and kept for personal use or sold later. In order to ensure that the time circle in the space ring can operate normally, she has to use snake crystals or medicinal materials to exchange for a large number of spirit stones, that is, at least to break even in the early stage, and when there are more medicinal materials accumulated in her hand, slowly the income must be greater than the expenditure.

Bai Xiaoxiao saw her look like a little money fan, and reminded: "Keep a low profile, whatever medicinal materials you want to sell in the future, just pass it from me, senior sister will help you manage the accounts, and turn a few more in the middle to prevent being targeted." ”

Tian Xiang'er said with a smile: "Senior sister is really thoughtful, but how can I be embarrassed to let my senior sister work in vain?"

Bai Xiaoxiao also smiled: "Then how are you going to pay for it?"

Tian Xiang'er blinked: "Between me and my senior sister, there is nothing to share, what is mine is yours, what kind of medicinal materials does senior sister want to use in the future, how many spirit stones are needed, although it is taken in our small treasury." ”

Bai Xiaoxiao took out an oversized Qiankun bag as if she was juggling: "Is this enough for a small vault?"

Tian Xiang'er leaned back with a smile: "The Qiankun bag is much more expensive than the storage bag, right? I didn't even think of buying this, but my senior sister actually bought it first, and she was really more fascinated than me." ”

Bai Xiaoxiao looked at Tian Xiang'er with gentle eyes, and smiled lightly.

There was only a little more than a month left before the one-year period, and Tian Xiang'er entered the realm three or four times faster than a disciple with the same qualifications because of the marrow washing effect of the chalcedony mixed yuan pill before, plus taking some Yangyuan pill that helped to cultivate, and Pei Yuan Dan that made up for the loss of true yuan, and Bai Xiaoxiao cultivating together. But compared to Senior Sister Bai's speed, she still can't catch up.

It took Tian Xiang'er four months to enter the Great Perfection stage of Qi refining from the late stage of Qi refining, while Bai Xiaoxiao only took one month to successfully build the foundation in the tower room on the third floor of Biling Pagoda.

There are nine floors in Biling Pagoda, the first and second floors are the cultivation places of the outer disciples, the third, fourth, fifth and sixth floors are the cultivation places of the foundation disciples, and the seventh layer and above belong to the disciples of the Yudan period, and the higher the tower layer, the richer the aura.

Bai Xiaoxiao told Tian Xiang'er that as long as there were signs of building a foundation, she would immediately inform her that she would choose a tower room on the third floor as a retreat place, and she would protect the Dharma for her at that time. After all, the aura of the third layer is much richer than that of the bottom two layers.

Before the retreat to build the foundation, Tian Xiang'er first took a pill of the foundation building pill and tried it preliminarily, but the result was unsuccessful.

Zhuji Dan could not be taken continuously, and it had to be taken seven or eight days before trying again, so Tian Xiang'er had to continue to strengthen the cultivation of the "Gu Yan Jue". However, it is worth rejoicing that the supernatural power of practicing the "Imperial Divine Formula" every night has also made great progress, and it has even reached the third level.

Originally, Tian Xiang'er wanted to strike while the iron was hot and practice controlling the devil, but Bai Xiaoxiao reminded her that the foundation was about to be built, and it was not appropriate to consume the true yuan for the devil, so Tian Xiang'er dispelled this idea.

In terms of mood, Tian Xiang'er is much calmer than in previous months.

Zhu Chenfeng has two letters every month, chatting with her about family life, telling interesting stories about Xiaoshi, which greatly alleviates her longing for Xiaoshi.

Especially last time she cried in front of Senior Sister Bai, Tian Xiang'er rarely cried anymore, she clearly understood that with her current strength, let alone protecting Xiaoshi, it was very difficult to even protect herself, instead of doing meaningless thoughts, it was better to concentrate on cultivation.

Yuan Mei expressed her gratitude for the gift, and brought back a letter from Zhu Chenfeng, saying that Xiao Shi liked the set of bows and arrows she sent, and after that letter, another piece of paper was attached, and Xiao Shi wrote a few big characters clumsily with a brush:

Thank you Aunt Xiang, I like it very much.

There is also a pouting grimace drawn on the back, as if he wants to kiss.

The son can actually write and draw! This page of tissue paper, Tian Xiang'er carried it with him like a baby, whenever he thought about a small stone, he took it out and looked at it, and gradually, his mood became more and more peaceful.

After taking the second Zhuji Dan, Tian Xiang'er felt that the aura in the dantian was mellow and full, and it seemed that it was almost at a critical point. After cultivating from Biling Pagoda on this day, Tian Xiang'er decided to go back and tell Senior Sister Bai that she was ready to retreat and build a foundation.

Unexpectedly, halfway through, Qin Duyan suddenly appeared and blocked her way.

Tian Xiang'er had a gut feeling that nothing good was going on, and sure enough, as soon as Qin Duyan opened her mouth, her voice was a little sarcastic: "Senior Sister Tian's cultivation speed, looking at the entire Qingqiong Sect, there are few people who can compare to it." According to your current state, I think Wu Zhen is bound to lose that bet. ”

If she said that when she started, she still had a good impression of this senior sister, but after Pang Ni's incident, she could see through it, this Senior Sister Qin was quite scheming, on the surface, she always looked righteous and awe-inspiring for the safety of the teacher, but in private, she was embarrassed with her junior sister to engage in some insidious little actions, if she hadn't used the seven-step snake to force Pang Ni to confess Qin Duyan, she would still be in the dark. Tian Xiang'er didn't have a good face at the moment: "What's the matter with you?!"

Qin Duyan sneered: "To put it mildly, if it weren't for Bai Xiaoxiao to take care of you, you would be where you are today?"

There are some things that you can understand by yourself and hear them from other people's mouths. Tian Xiang'er is not a fool, she has been in business for almost a year, and Bai Xiaoxiao's kindness to her has reached the point where everyone knows about it, how can she not know it? This is like a whirlpool, she has fallen into it from the beginning, and if she wants to jump out, it will be as uncomfortable as cutting her heart and cutting her flesh.

She didn't know when she started treating Senior Sister Bai as her own person, and only allowed herself to say Bai Xiaoxiao, but she didn't allow others to say it behind her back. Tian Xiang'er immediately sneered: "What's wrong with Senior Sister Bai being good to me? Are you jealous? If you have the ability, you can also find a senior sister to love you?"
