We determined the location and used GPS and compass to navigate. The five of us rode camels south along the Cherchen River's main watercourse.

After spotting the water source, the rolling yellow sand quickly turned into patches of green meadow, and the temperature and humidity changed dramatically.

Walking by the river no longer felt as scorching as in the desert, but as the altitude increased, the temperature dropped lower and lower. We had to put on the adventure gear we had prepared in advance to keep warm.

We crossed the edge of the desert and walked all the way to the Muztagh Ata peak, the source of the Cherchen River, on the northern slope of the Kunlun Mountains. Muztagh Ata peak is 6,973 meters above sea level, located in the southwest corner of the Arjin Mountain Nature Reserve in Ruoqiang County, southern Xinjiang, bordering Tibet. It is the highest peak in the eastern Kunlun Mountains.

Fatty looked at the towering Muztagh Ata peak in the distance and asked, "Hey, Master, not that I doubt you, but are you sure this way south, out of the desert and to the edge of these Kunlun Mountains, is the right way?"

The route was definitely right, but I couldn't say the reason directly, so I hedged a bit and replied, "Based on my intuition and judgment, this is the right way, no mistake."

I knew that Fatty wouldn't easily agree with just this one sentence, so I continued, "Fatty, Rouyi, do you still remember our experience in the underground ancient city in the desert?"

Fatty and Rouyi said they still had an impression.

I then said, "You should also remember the murals in the underground ancient city about the Kunlun Mountains, right?"

Although I had no impression of the underground ancient city, Fatty and Rouyi had told me the story of the underground ancient city before, so I naturally knew what they had experienced inside.

Fatty slapped his head, "Oh yeah, I remember! The content of the mural at the time was Zhang Jiao seeking medicine. His destination to the west was the Kunlun Mountains!"

Rouyi also seemed to recall the situation at the time. Her eyes were a little erratic, and she hesitated, slowly saying, "Master, I remember when you got the iron mask, you said you would find the Kunlun Divine Void through the iron mask... So, is the reason for your judgment related to the iron mask?"

Faced with Rouyi's question, I was a little dumbfounded, because I didn't remember this experience at all. I didn't even know what the iron mask was.

Fatty's face was full of doubt at this time, and he asked, "That's right, is our trip to Kunlun related to Han Yu?"

I didn't expect that mentioning the underground ancient city not only didn't get me past this, but instead made Fatty and Rouyi think of other things.

I had to get them back on track, so I replied, "Regarding the things in the underground ancient city, I really don't have any memories left in my mind. If my words pointed to Kunlun at that time were just a coincidence, then my waking up from the desert, to the Z organization's pursuit, and then Han Yu's disappearance, later, we came to the desert, found the stone coffin, and traced it according to the poems... All of this, wouldn't it still be a coincidence?"

This time, Fatty and Rouyi stopped talking, but fell into deep thought. I think they should be thinking about the logical relationship of these things.

Because what I said made sense, and it was the truth, but there was no direct evidence.

I looked up at Muztagh Ata peak and the peaks behind it, and said to Fatty and the others, "Han Yu is in these peaks."

Kunlun Mountains—an absolute forbidden zone.

There is a powerful magnetic field in the Kunlun Mountains, which will cause all electronic equipment to fail. Among them, the Na Lenggele Valley is also known as the Valley of Death. The magnetic anomaly phenomenon in the valley is very obvious, and it becomes more and more obvious as you go deeper into the Kunlun Mountains.

The strong geomagnetic effect in the Valley of Death can also cause natural phenomena such as lightning and even tip discharge, killing stray herders and animals.

Moreover, after humans enter the Kunlun Mountains, it will also change people's biomagnetic field, thus causing people to lose their way. In addition, there are many wild animals in the Kunlun Mountains, which is very dangerous, so the country strictly prohibits tourists and explorers from entering the Kunlun Mountains to explore.
