"Since I can't control the yin qi now, then I am not in a hurry to learn this method of Yan Junling's shuttling between yin and yang, and I will definitely return to the yang world to bring entertainment tools to the three seniors when I have time in the near future." After Su Lin finished speaking, he said goodbye to the Three Pavilion Yan Jun, and then returned to the underworld from Yan Jun's order.

The time back to the underworld did not pass too long, Su Lin was also thinking about how to convert the yin qi into spiritual power, but after thinking for a long time, he didn't come up with any way, so he lay down to rest, fortunately, in the underworld, these spiritual and earth fairy girls need to sleep, this Su Lin felt that they were no different from Su Lin, but recently Su Lin found that Su Lin had less and less time to rest, since Su Lin came to the underworld, Su Lin had not eaten, not even a sip of water, but Su Lin did not feel tired.

At this time, Su Lin thought that in the yang world, Lingcha and Earth Immortals do not need to eat, drink and rest, and when they return to the underworld, they are like normal human beings, so whether Su Lin is in the silver armor is equivalent to them in the yang world, and they don't need to eat and drink to rest, if this is the case, it would be great, Su Lin, who originally ate and drank in the underworld, is different from other Lingcha Earth Immortals, if he always returns to the yang world to get food, it will definitely be very troublesome, now it's good, Su Lin doesn't need to eat, drink or rest in the underworld, It's a lot more convenient.

The underworld is also divided into black sky and daytime, but unlike the yang world, there is no sun and moon in the underworld, and the day and sky here will be white, but there is no light, but Su Lin can see the surrounding things clearly with the naked eye, and the sky will gradually dim at night, and the surrounding darkness is something that Su Lin can't see with the naked eye, but the residents of the underworld can, and Su Lin didn't figure out what was going on.

When the sky was dark, Su Lin heard the sound of the camp and the sound of the rope, and then the military horn sounded, originally Su Lin thought that something was going on, but if there was a situation, Lin Ranyue and they should have informed Su Lin, thinking of this, Su Lin also hurriedly went out of the tent to check, it turned out that Qingya was training early in the morning, and these soldiers were called up by Qingya to train one by one.

Su Lin and Qingya live in the mountaintop camp in the east, Lin Ranyue and Xu Nuan are also here, and Yuxiang and Nianluan are on the peak of the west side, because Yuxiang is smart and clever, and he is also good at some military affairs, although Nian Luan will lead the troops, but the management of the troops is definitely not as smart as Yuxiang, this Su Lin let Yuxiang stay on the west side is also to be the military advisor of the west camp, if something happens to Su Lin's side, there is also Yuxiang over there to give advice, and this is also just in case.

The two mountains are not far apart, although it is a little difficult to see the appearance of a person, but in general, it is possible to see the situation of the other party's camp, and the camp on Yuxiang's side is also starting to get up one after another, it seems that Nianluan is also preparing to train soldiers, Qingya and Nianluan have something to do.

During this time, Su Lin wanted to study how to convert the yin energy of the underworld into spiritual power, which Su Lin estimated that he couldn't think of, so Su Lin also planned to go back to the yang world, and it was estimated that Mao Sanci might have a relatively high interest in these, and if Mao Sancion made a move, it was estimated that he would study it.

After explaining some training things about Yuxiang and Qingya, Su Lin took Lin Ranyue and prepared to return to the yang world, Yuxiang was not very happy at first, and felt that it was a little unfair for Su Lin to take Lin Ranyue without her, but when he thought that the camp was now in need of stability, Yuxiang also stayed, Su Lin was not familiar with the road to the underworld, Qingya also took Su Lin and Lin Ranyue from Yinquan Village to the gate of the underworld, the gate of the underworld has now been sealed with an exorcism array, Su Lin doesn't know what kind of formation this is, As long as it is an evil spirit or other souls that are not bad spirits, they can't pass through this gate, this formation can be described as very powerful, before leaving, Su Lin also gave Qingya a few communication charms, if something happens, you can also notify Su Lin as soon as possible, after all, the underworld is still relatively chaotic, and Qingya takes the communication charm to ensure that as long as there is him, the team will continue to develop decently.

Passing through the underworld, Su Lin and Lin Ranyue appeared in a woodland in the Tianshu Branch, this woodland is the place where the jacket and the ink took Su Lin to the underworld, it seems that where this goes from there, it has to come from where.

"Senior brother!" Mao Sanci didn't know how to learn the news of Su Lin's return so quickly, and before Su Lin walked out of the woodland, he greeted him, and Su Lin was relieved to see that he was wearing the robe of the head of the Tianshu Branch, and it seemed that Su Lin had almost handed over the positions of the younger generation of the Master Pavilion during the time he went to the underworld.

Fang Xinyi looked at Su Lin outside the woodland at this time, looking at her resentful eyes, Su Lin also hurriedly took his eyes away from her gaze, and he didn't know how long it had been since Su Lin left, and he still missed his partners Su Lin very much, but Fang Xinyi had something special, this little girl wanted Su Lin to marry her, not to mention whether she was joking with Su Lin, anyway, Su Lin was merit and couldn't stand it.

"Sancion, how many days have I been away?" Su Lin asked.

"It's good that you're going, it's been more than half a month now, what are you eating in the underworld? I remember that you didn't bring any food with you when you left, so ...... during this time" Mao Sanci looked at Su Lin suspiciously, but Su Lin was not too surprised, after all, the days in the underworld should indeed be more than half a month, so it seems that the time in the underworld is the same as in the yang.

"Senior sister, senior brother is back, you should come over quickly." Mao Sanci shouted Fang Xinyi, Fang Xinyi is a little different from before this time, if you ask Su Lin what is different, that is, she is not as lively as before, Su Lin doesn't know if she became like this after seeing Su Lin, Fang Xinyi heard Mao Sanci shouting her name and didn't come over but turned around and left, this girl Su Lin didn't know what she was thinking,

"Sanci, what has happened to Fang Xinyi lately?

"I also heard that, because now after all, the head of the Tianshu Branch often has to hold an elders' meeting, a few days ago someone seemed to say that the senior sister seemed to be dropping out, as for the reason, they didn't tell me, and I didn't take it to heart at that time, after all, the senior sister didn't say to quit school, maybe it was the gossip that other people heard." Hearing Mao Sancion say this, Su Lin felt that this matter might be true, Fang Xinyi's abnormal reaction might be something wrong with the family, if so, Su Lin couldn't look at it, after all, Fang Xinyi had helped Su Lin many times.

"Sanxi, in other words, senior brother has been thinking about something recently, you said that there is any way to convert one spiritual power into the power of other interfaces, to put it bluntly, I want to convert the yin energy of the underworld into spiritual power, is this possible?" Su Lin asked, and Mao Sanci thought very seriously after listening to Su Lin's words.
