Flicking the finger divine sword consumes a lot of internal force, and after making a rough stone bowl, Tang Mingyu felt that the internal force was lost a layer.

Tang Wuji told Tang Mingyu that the use of the Finger Flick Divine Sword required careful calculation, and it was necessary to use the least amount of internal force to achieve the best effect.

For example, Tang Mingyu's carving just now wasted too much internal force.

Of course, it is okay to waste internal force in the process of practice, but it is better to consume more, so that the internal force will increase faster.

Every once in a while, Tang Mingyu would sit cross-legged on the stone bench and cultivate the Shaoyang True Qi or the Nine Phoenix Devouring Heaven Recipe to restore the lost True Qi.

After her true qi had regained her true energy, she continued to use the flick sword to carve the stone bowl.

From the initial ordinary rough stone bowl, Tang Mingyu gradually made all the progress, and later the stone bowl she carved out was not only smooth and round, but also carved with ornaments on the outside of the bowl.

This is Tang Mingyu carved according to the blue and white porcelain decoration in his memory, making the stone bowl look very exquisite.

Tang Wuji saw that Tang Mingyu had reached such a skilled state in only three days of hard work, and not only praised him: "Xiaoyu, you are really a good seedling for martial arts, and your father-in-law is proud of you." ”

Tang Mingyu himself felt very happy, and said with a smile: "Father-in-law, this is all because you have taught it well, Xiaoyu can master it so quickly, thank you, father-in-law." ”

During this period, Tang Wou-Ki's care for Tang Mingyu can be described as considerate and subtle, Tang Mingyu only needs to carve and practice martial arts, and other things such as catching fish and grilling fish Tang Wou-Ki will take care of it single-handedly, and send the grilled fish to Tang Mingyu's mouth.

There is no flint or firewood here, and the grilled fish is directly cooked with real gas turned into fire, and the seasoning is very simple, only salt.

This salt is very precious, it was Tang Wuji who searched for a long time in the underground dark river to find a place with a salt mine, packed it in a prepared stone bottle, sealed it with true qi and brought it from underwater.

Due to the lack of some seasonings, the fish grilled by Tang Wuji was naturally not as delicious as Long Yi, but Tang Mingyu knew that in such a bad environment, it would be good to eat it, so naturally he would not dislike this or that, and the food was still quite fragrant.

And during this period of time, Tang Wuji has also had the happiest time.

It would be a lie for a person to say that he was not alone in this underground cave, and now there is someone who can chat with him, and he is also the righteous daughter he adopted back then, his smile often blooms, even if he really can't get out, he will not feel lonely anymore.

There are always inconveniences between men and women, and Tang Wuji also deliberately used stones to separate Tang Mingyu from a small room in the cave, so that she could have a private space.

In this regard, Tang Mingyu was very moved, although this father-in-law actually had nothing to do with her, but in this strange world, she really felt the fatherly love from Tang Wouji.

Psychological acceptance, so that Tang Mingyu quickly treated Tang Wuji as a father, and he got along very casually on weekdays, and occasionally coquettishly with his father-in-law, and had a comfortable life.

It's just that she has eaten grilled fish for a few days, Tang Mingyu is a little tired of eating, she hasn't gone down to the underground river to find food, she has been practicing carving for a long time this day, so she said coquettishly: "Father-in-law, I'll go with you to catch fish today, okay?" ”

Tang Wuji was slightly worried and said, "Xiaoyu, are you okay?" ”

Tang Mingyu grinned and said, "Father-in-law, I have lived in the underground river in the belly of Longmen Mountain for a period of time, don't worry, these will not be difficult for me." ”

Tang Wuji heard her say this, coupled with Tang Mingyu's advanced cultivation and understanding of the technique of holding his breath, he thought that it should be no problem, so he nodded and smiled: "Okay, then let's go down together." ”

Tang Mingyu's Nine Phoenix Treasure Clothes have the function of avoiding water, when she goes down, the water seems to automatically retreat, and it will not invade her clothes, even if it is her face, as long as she wears a hood and covers her veil, these materials will automatically fit the skin, and will not let the water seep in, only the eyes are exposed to the water.

Tang Wuji had already known about the Nine Phoenix Treasure Clothes on Tang Mingyu's body these days, and those stone chips would not adhere to her at all, which made him secretly amazed, and now seeing that it could avoid water, he couldn't help but sigh that his daughter's good luck was able to get the legendary Nine Phoenix Empress's treasure clothes.

Tang Wuji is extremely fast because he catches fish in the water all year round.

And Tang Mingyu wore the Nine Phoenix Treasure Clothes, which seemed to have the role of a water reliner in the water, and he had already practiced a good diving technique with Long Yi, so he was not under his father-in-law at all.

The underground river in the desert was turbulent, stretching from the waterhole to the distance, and the two communicated through transmission.

Tang Mingyu knew from his father-in-law that the underground river stretched for hundreds of miles, and he didn't know where it led, at least for the time being, his father-in-law didn't find an exit, which showed that this underground river was really meandering.

Tang Mingyu had heard that there was also an underground river under the Devil's Quicksand River, which would not come out of the ground until Phoenix Town.

So this place is so close to the Devil's Quicksand River, could it be connected to the Devil's Quicksand River?

If this is the case, then you can walk through the underground dark river and then look for the underground phoenix city below the Devil's Quicksand River.

Tang Mingyu told his father-in-law his thoughts through transmission.

Tang Wuji could naturally think of what Tang Mingyu could think of.

Tang Wuji told Tang Mingyu that he had also been trying to find the underground Phoenix City, but unfortunately, the underground dark river was accessible in all directions, and it was very easy to get lost, and although the martial artist could use the technique of holding his breath, he could not hold on for a long time, so he could not find too long and too far away.

Tang Mingyu felt that his father-in-law was right, if he was reluctant, it would be easy to recover, and only by living could there be hope.

The underground river here is a little different from the one in the belly of Longmen Mountain, and Tang Mingyu always feels that there are traces of artificial excavation, which is easy to find with the knowledge she has learned from archaeology.

Moreover, she found a carved handwriting in Sanskrit on a corner of the underground river, an oriental character with Arabic numerals on it, which she saw was 21.

East 21, what does it mean?

Could it be the location 21 from the east gate of the underground Phoenix City?

This discovery made Tang Mingyu pleasantly surprised, "Father-in-law, look here." ”

"Xiaoyu, what does this mark mean?"

"East 21 should be a sign of direction, if we can find the next marker, maybe we can find a pattern."

"Xiaoyu, you even know this, it seems that you have learned a lot over the years, and my father-in-law is really proud of you."

"The righteous father praised it falsely, this is something that Xiaoyu learned by accident, and it is not worth mentioning."

While talking, the two continued to swim forward, and there were all kinds of fish along the way, all of which were fish that the two of them often ate, and it was not strange to see them.

With a purposeful search, after a quarter of an hour of groping, the two found another mark at the bottom of the confluence of the next dark river, and Tang Mingyu found that it was Dong 20.
