readx; With a total length of more than 5,400 kilometers, the Yellow River is the second longest river in China and one of the birthplaces of Chinese civilization, so it is also often known as the mother river of the Chinese, the Yellow River starts from the Qinghai-Tibet Plateau in Qinghai Province, flows through Qinghai, Sichuan, Gansu, Ningxia, Inner Mongolia, Shaanxi, Shanxi, Henan and Shandong nine provinces, and finally flows into the Bohai Sea.

For the general trend of the Yellow River, Yu Fei still has some understanding, from west to east in a zigzag distribution, and this Tibetan sword map is obviously not the whole picture of the Yellow River, it should only be a small section of the Yellow River, in order to be able to determine the specific location of the Tibetan sword, Yu Fei quickly went online to find out the map of the nine provinces and cities through which the Yellow River flows, and then carefully compared one by one.

Finally, he really found a section of the Yellow River channel trend map that was quite similar to the lines connected to the ripple logo on the Tibetan sword map, which made Yu Fei pleasantly surprised, which showed that his thinking was not wrong, Xuanyuan Xia Yu Sword was most likely hidden at the bottom of the Yellow River, and the place where the sword was hidden was located somewhere in this section of the river.

Yu Fei became more and more energetic, and immediately studied this section of the Yellow River, he roughly calculated according to the scale on the map, this section of the river is about more than 100 kilometers long, and the whole section is located in Shaanxi Province, and when he checked the terrain characteristics of this section of the Yellow River on the Internet, he couldn't help but be stunned, he didn't expect that the Hukou Waterfall and Longmen of the Yellow River are located in this section.

Longmen,,These two words made Yu Fei's mind suddenly excited,Isn't the Yellow River Dragon Gate exactly the place where King Dayu used the Xuanyuan Xia Yu sword to split,It seems that he is in the right place,Presumably after King Dayu split the Dragon Gate,Xuanyuan Xia Yu sword was buried at the bottom of the river near the Dragon Gate,

Thinking of this, Yu Fei was excited, and he didn't care that it was more than one o'clock in the morning, so he immediately booked a ticket online to fly to Xi'an, Shaanxi Province the next morning, planning to go from Xi'an to the Yellow River Longmen again, this time, he planned to go alone to find Xuanyuan Xia Yujian,

On the one hand, now that Bai Yiqing's vitality has not recovered, Kun Yuanzi is missing again, and the gap between other people's cultivation and his own is too big, I'm afraid it won't help much, even if he goes, it's a drag, on the other hand, Yu Fei thinks that if Xuanyuan Xia Yujian is really the key to dealing with the upcoming shocking catastrophe, then it's best to know as few people as possible,

The next day, Yu Fei arrived in Xi'an by plane, Xi'an to the Yellow River Longmen there are more than four hours of driving, when he arrived at Longmen, it was nearly evening, but Longmen is a very famous scenic spot, even if the sun has set, there are still a lot of tourists on both sides of the river, it is not convenient to move, if he is now in the water, I am afraid that it will be mistaken for jumping into the river to commit suicide, maybe someone will immediately dial 110 to call the police, so it is better to wait until the tourists are dispersed and then act,

Of course, Yu Fei is actually not in a hurry, he just plans to take a good look at the terrain of this dragon gate this time, find the best place to go into the water, and then prepare to buy a set of special diving equipment, although he can use the turtle breath technique to dive into the water, but the Yellow River is too turbid, you have to get a diving goggles or a diving mask or something to cover your face, otherwise I am afraid that a little mouth, the mouth and nose will be stuffed with mud and sand, and besides, looking for Xuanyuan Xia Yu Sword at the bottom of the river must not be a matter of a while, So it's more reliable to carry an oxygen tank,

His plan was to wait until late at night the next day to make his move, anyway, after reaching the bottom of the Yellow River, it was estimated that he would not see anything, it didn't matter if it was day or night.

Yu Fei found a high ground on the bank of the river and squatted down with a panoramic view of Longmen, and began to observe carefully.

Both sides of this dragon gate are continuous mountains, the mountain is very steep, it seems to be split by a sword, the whole section of the river is less than 40 meters wide, compared to the Yellow River channel that is often hundreds of meters wide or even several kilometers, it is indeed like a "one man is not open" Tianmen, the waves in the river are turbulent, the yellow waves are rolling, it seems quite dangerous,

Seeing this situation, Yu Fei couldn't help but feel a little puzzled in his heart: "According to the marks on the map, Xuanyuan Xia Yujian should be located in a large area with a large water flow, and this Longmen terrain is so narrow, although the water flow is very fast, but the total amount of water flow should not be large, either because he found the wrong place, or he understood the wrong sign."

He pondered for a while, and finally decided to explore the dragon gate first, after all, this dragon gate is the last place where the Xuanyuan Xia Yu sword appeared, and it is also the most likely place to hide the sword, maybe that sign is not just a simple indication of the flow of water, and then say, if you can't find it in this dragon gate, it's not too late to look for it in other places, anyway, it's just more than 100 kilometers, it's a big deal to turn this section of the river upside down, there are a few dragons to help, it must not be difficult for him,

That night, Yu Fei found a hotel near Longmen to stay, and early the next morning, he went to buy the items needed for diving.

Diving glasses are easy to find, after all, they are the most commonly used diving equipment, even if they are used in the swimming pool, so they are sold in general supermarkets, but Yu Fei picked up a pair of diving glasses and took a look, and immediately felt that wearing such a pair of glasses was probably not enough.

Diving mask is a more professional diving equipment, want to find a store specializing in selling diving equipment in such an inland city, it is not an easy task, think about it, unless the head is kicked by a donkey, otherwise who came to this place to sell diving equipment, presumably no one will go to the Yellow River diving,

Yu Fei almost searched this small city next to the dragon gate, and did not find a shop that sold diving equipment, and finally found a salvage company specializing in salvage and search and rescue of wrecks under the advice of others, and spent nearly twice the price on the market to buy a new set of seven-layer diving equipment.

That night, Yu Fei waited on the edge of the Yellow River until more than one o'clock in the morning, and through the observation of the day, he had found an excellent place to launch the water, located directly below a cliff, which could not be passed from other places on land, and was relatively hidden, from which it was not easy to be discovered.

In fact, if it was just Yu Fei who went into the water alone, after dark, as long as he secretly found a place to drill into the river, it is estimated that no one would find out, the key is that he still has to summon the dragon to go with him, the dragon is huge, in case it is discovered, it will be a big trouble.

After confirming that there was no one else in this area, Yu Fei put on a full set of diving equipment and summoned the golden and white dragons, among the five element dragons, only the fire dragon did not like water, and the gold and water dragons were both water-loving dragons, and they could move freely in the water, Yu Fei settled down, and led the double dragon into the gasping river,
