Ning Xi introduced it specially, Xi Rui also developed a bit of interest in Luo Yinhuang.

"You can actually improve this formation." Since he is the man of his niece, he is not stingy to teach him.

Luo Yinhuang smiled a little, "Senior Xi please give pointers."

He found out when he was in the red worm's lair before, that Xi Rui's talent and level in the formation method were very high.

If he can communicate with the other party and get some pointers, he may be able to figure out the bottleneck of the stuck and be promoted to the level of the high-end array.

"We can exchange one or two." Xi Rui stood up and walked to an empty sofa next to him and sat down, beckoning to Luo Yinhuang, "Come and sit!"

Luo Yinhuang knew the relationship between Xi Rui and Ning Xi, and was not hostile to each other, so he stood up and sat over.

Xi Rui moved his fingers and threw two stones engraved with the formation at any time, and then formed a circle of light around the two of them.

People outside couldn't hear what they were saying.

The two began to discuss and exchange the formation method, and Ting Feng and others pouted, this alien is really stingy.

Obviously, I want to communicate with Luo Yinhuang, a genius of the formation, and I also want to gain benefits. I also look like I am afraid of being eavesdropped on by others. I hate it!

The formation arranged by Xi Rui was very special, Ning Xi could hear their conversation, but others couldn't.

So Ning Xi listened to their exchange of experience on the formation while cultivating. The more advanced ones were still incomprehensible, but most of them were very helpful to her after listening to them.

Luo Yinhuang and Xi Rui communicated for three days and three nights. After Xi Rui removed the aperture and returned to the original position to sit down, Luo Yinhuang was still immersed in the previous harvest and understanding, and no one disturbed him.

The formations of alien races and human races are slightly different in terms of comprehension, laws, and arrangement methods, but they can also promote each other.

Because of Ning Xi's relationship, Xi Rui didn't keep much of Luo Yinhuang's advice, and it was considered to be a more dedicated solution to the confusion.

It made Luo Yinhuang suddenly enlightened in many aspects. What he hadn't understood before in terms of inheritance, he also realized it because of this guidance.

Luo Yinhuang has gained a lot, and Xi Rui has also gained something. This is an experience that has never been possible before communicating with the Xuanzong-level Array Master.

He found that this little guy's formation talent was too enchanting, and his comprehension was even more perverted, but this was worthy of Ning Xi.

In addition to the grottoes, there is another dangerous area in this area, and there are some plants that give birth to spiritual intelligence and will raid.

However, they were easily solved by two Xuanzuns, Xi Rui and Tang Di.

After half a month, they flew to the more dangerous area of ??the second listening vent.

This is a black swamp, the swamp is very wide, and there are many black mountains in the middle and edges.

The swamp exudes a thin layer of black mist, which secretes a kind of weightless energy, so not only war beasts, but also flying mounts can't normally fly over the swamp, and they need to come down and walk over by themselves.

In dangerous places, there will naturally be some high-grade treasures.

Ning Xi looked at the map and showed that there was a kind of dark flower with relatively high value growing in this swamp. It could be used to refine an elixir that increases the success rate of Xuanzong's promotion to Xuanzun. The essence was extracted separately and refined into liquid. It can improve the cultivation of Xuanzong.

Once the dark flower is found and put up for auction, it will sometimes fetch a higher price than the high-end medicine pill.

Therefore, many mercenary groups will venture to this swamp to find the dark flower.
