Tian Xu put away the demonic beasts that were to be put into the Yin-Yang Ding, and found that the space inside the Yin-Yang Ding was not as full as before, and it seemed that some could be installed. When I looked at a few more space rings, I could already see that the demonic beasts that were neatly arranged in Ziyan were at least a quarter smaller than when they were placed casually, so the four rings added up to free up about one ring of space in total.

"Yes, Ziyan, you have contributed a lot to tidying up, and you have freed up so much space. Tian Xu was full of praise for Ziyan's work.

Ziyan asked Tian Xu about the situation of the sea knowledge space, and learned that he had found a way to expand this space, and was able to expand the size of the sea of knowledge by expanding this small space, and was also very happy, and said: "If it continues like this, will you be able to have the ability of soul cultivation? ”

Tian Xu smiled: "This is not good, at least it is not easy to succeed." In the beginning, it was easy to expand that small space, but in the end, it became very difficult to expand a little bit. It seems that it is still necessary to increase the mental power as much as possible in order to expand this space even more. I guess this small space may be my mother who gave me spiritual power to cultivate. She originally said that I didn't have the talent to become a soul cultivator, but she gave me this at this time, maybe she wanted me to strengthen my mental power as much as possible so that I could cope with future disasters. ”

The two discussed the matter of knowing the sea for a while, and then packed up their things and set off to continue to Kunlun Mountain.

Now that they had abandoned the car, they no longer made a detour from the desert, but corrected the direction with the map of their mobile phones and flew along a straight path towards Kunlun Mountain. At the speed of the two of them, they could fly about 200 kilometers per hour, and the Ziyang Peak where the Kunlun faction was located was in the southwest direction of them, with a straight-line distance of about 1,500 kilometers, and they could reach it in one day anyway.

They say they are walking in a straight line, but in fact they don't really glide in a straight line, not because of anything else, but just to avoid flying too much in the high-altitude mountains. The route they chose was to follow the northern side of the Kunlun Mountains.

The Kunlun Mountains are the watershed between the Qinghai-Tibet Plateau and the Tarim Basin. If they enter the Kunlun Mountains too early, they will have to climb one dangerous peak after another, unless they can fly at an altitude of more than 5,000 meters. But now it is winter, the strong northwest wind is blowing strongly, the low temperature and low oxygen in the high altitude have little effect on them, but the forward resistance brought by the northwest wind still has a significant impact on their progress.

In addition, if you fly high in the sky, the scenery around you is monotonous, and the comfort level is much worse than flying in the gentle desert.

They flew along the foot of Kunlun Mountain, and another purpose was to make a detour to the famous Hetian jade production area to see if they could find spiritual jade there. Tian Xu is now a little fascinated by studying formations and talismans, and the number of spirit jade and spirit rhino fingers that can be used to make arrays in his hand is really limited, and the few formations and talismans that he tried to make in the Medicine King Bucket have already consumed most of the materials in his hands, and if he doesn't add some more, there will be no spirit jade available.

Although he had just bought some spirit jades in Xiduotang, the quality of those spirit jades was really not high, needless to say that they were far inferior to Lingxi Fingers, and even the spirit jades he and Ziyan found in the Qinling Mountains were much stronger than those sold by Xiduotang. The twenty pieces of spiritual jade he bought from Kitado were only intended to be used for hand training. If it is used to make a formation that satisfies him, it is too far off. Tian Xu didn't want to throw out more than a dozen pieces of spirit jade at a time in order to cast an ordinary formation, he couldn't afford to lose that person.

The Yulong River near Hotan is a famous Hetian jade production area. Although he wasn't sure that he would be able to find a high-quality spirit jade from there, he could still try his luck by the way. He's always been lucky, and maybe he'll be able to find what he's looking for. What's more, the road is not far.

The two flew all the way, and after five hours, they finally saw a valley covered with ice and snow, which should be where the famous Yulong River is located from the map of the mobile phone.

Winter is not a good time to look for jade, and even local professional jade pickers do not go up the mountain in winter. Not only because of the harsh weather in winter and the difficulty of walking, but also because after the snowfall in winter, the river valley is covered with snow, which brings great difficulty to finding jade. But this will not cause Tian Xu any trouble, because he has a unique sense of olfactory imaging.

The Yulong River originates from the Kunlun Mountains, flows from south to north, and is gradually absorbed and dried up by the desert after entering the Taklamakan Desert. Hotan City is located just outside the valley, and the river valley where local jade miners search for jade seeds is just upstream of Hotan City, not far into the mountains.

Due to the monsters, the population of Hotan City has been evacuated to the interior, leaving behind only an empty city with no people. The two of them did not enter the city, and after reaching the Jade Dragon River Valley from between the city and the mountains, the two turned to the mountains and searched upstream along the valley to find traces of the spirit jade.

Tian Xu carried out olfactory imaging, not only exploring the river beach in the river valley that has been turned over by the excavators of jade miners, but also paying attention to the mountains on both sides.

This winter, the snowfall in the Hotan area is not too large, and the snow in the Yulong River Valley is only less than a foot thick, and Tian Xu's olfactory imaging can easily see through the snow and find abnormalities below. In the process of searching, he has found the imaging characteristics of jade, and according to this feature, he has found more than a dozen pieces of jade, large and small, on the river beach that has been repeatedly excavated and searched, two of which can be regarded as excellent seed material if viewed from a secular point of view, but it is meaningless to Tian Xu, and he threw it back without care.

After tracing more than ten kilometers along the river, the peaks on both sides gradually became steeper, and the river valley became narrower and narrower, only ten or twenty meters wide.

Just as they turned the corner of a cliff, a burst of high-frequency electromagnetic waves suddenly emitted from the cliff, shining directly on the two of them. This electromagnetic wave is very special, it has a fixed frequency, and it is obviously a means of attack.

Tian Xu was a little surprised, in the previous flight, he had not observed any traces of people or demonic beasts here, so this attacker was either located at a distance that his olfactory imaging could not reach, or he had a powerful hiding method that deceived his detection.
