Han Li wanted to see how tough this gray cloth really was, and he increased his strength again, but until he used all his strength, he still couldn't tear through this gray cloth.

He looked at the gray cloth, his eyes full of curiosity.

After a moment's hesitation, he flicked his fingers, and a cloud of crimson flames flew out, enveloping the gray cloth.

The flames burned brightly, emitting a scorching heat, but the gray cloth remained unchanged in it.

Han Li dispersed the flames with a single wave of his hand, and with a wave of his hand, a stream of water light enveloped the object.

Silky blue light emerges from the water, wrapping around the gray cloth.

The gray cloth still hasn't changed a bit.

Han Li's brows furrowed slightly, and with one finger, five golden thunderbolts emerged, covering the gray cloth......

Half an hour later, Han Li looked at the gray cloth in his hand with a helpless look on his face.

During this time, he tried almost every method he could think of, and even a stone squeezed out the oil.

But the gray cloth is not in the oil and salt, and there is still no movement.

"There should be something special about what Xiong Shan doesn't want to exchange even if he goes bankrupt. Forget it, let's study it slowly when we have a chance in the future. Han Li smiled helplessly and put away the gray cloth.

At this moment, the cyan ball of light around Lu Yuqing's body flashed a few times, and then disintegrated, turning into a ball of bright blue light and integrating into her body.

When the woman opened her eyes, her complexion had recovered most of it.

"Brother Han, I'm sorry to keep you waiting. She stood up and said to Han Li.

"It doesn't matter. Let's see, is there a way to determine the approximate location of this area?" Han Li said with a wave of his hand, glancing at the black stones all around him, and then looking up at the dark yellow sky.

"As far as I know, the terrain in the cold territory is already complex and the environment is different, and there is not only one Gobi region like this. Based on what I've seen now, I can't tell where this is. Lu Yuqing shook her head and said.

"Let's take a look around first, this place is desolate, but it can't be underestimated. Han Li said, waving his hand to sacrifice the Green Kite Flying Boat and stepping into it.

Lu Yuqing naturally had no objection and fell into the flying boat.

With one hand, Han Li urged the law to decide, and the surface of the flying boat lit up with a blue light, and it flew away in a certain direction.

The area here was the same as the Blizzard Ice Sheet that had passed before, and there was also an invisible force that limited the spread of the Divine Sense, and with the strength of Han Li's Divine Sense, it could only spread hundreds of miles away, so the speed of the flying boat was not very fast.

After a moment, Han Li's eyebrows raised slightly, and he looked in a direction ahead, and the Green Kite Flying Boat under his feet also paused slightly.

"Brother Han, what did you find?" asked Lu Yuqing.

"I found something, but it's not very precious. Forget it, let's go over and take a look. Han Li nodded, and the flying boat deviated slightly from the direction and flew towards the left front, quickly flying more than three hundred miles and stopping.

The two of them floated down from the flying boat and landed on the ground.

A large number of purple-black mushrooms grew on the ground below, each one a foot high, and dark purple circles appeared on it, and the edges were bright red, which looked extremely gorgeous.

This mushroom group covers a large area, about one acre, as if a sea of gorgeous flowers grows on this desolate Gobi, which is very abrupt.

"This is Moyun Mushroom!" Lu Yuqing's beautiful eyes lit up.

"Could it be that you have judged the location of this place from this Moyun poisonous mushroom?" Han Li's eyes flashed and he asked.

He had also seen the record of the Moyun mushroom, which contained highly poisonous mushrooms and could be used to refine some poisons or magic weapons with highly toxic attributes, but its toxicity was limited, and it was only effective for monks below the True Immortal Realm.

"Not bad. Lu Yuqing said with some excitement.

As she spoke, she flipped over and took out a piece of jade and waved her hand to shoot out a blue light that didn't enter it.

Streams of green light emanated from the jade jue, condensing into a wall of turquoise light.

On the wall of light is a map, made up of a dozen parts of different colors, which does not look complete, and seems to be only about half of the complete map.

"This is the map of the Cold Realm that you collected on Black Wind Island?" Han Li asked, looking at the map.

"That's right. According to the information we have gathered on Black Wind Island, there are nearly 100 regions with different climates and environments in the cold territory, but unfortunately I only got the map information of more than a dozen of them. Lu Yuqing nodded and said.

Han Li nodded thoughtfully, his gaze wandering back and forth over the wall of light.

The map is very well made, and some of the environments in different areas are vividly delineated, and you can roughly judge the specific situation of those places from the map alone.

But I didn't find the map of the Blizzard Ice Field, the Pitch-Black Mountains, and the Black Sea that I just passed.

"I don't know the location of the three areas we passed through before, otherwise I wouldn't have been so passive before. Lu Yu seemed to see Han Li's doubts and said.

"Then where are we at the moment?" Han Li asked again.

It was only at this moment that he had a general impression of the cold realm.

"Here, this black Gobi area is called Black Rock Gobi, according to the information we have gathered, although there are three or four Gobi areas in the cold country, only this black rock Gobi has a lot of Moyun mushrooms growing, we should be here. Lu Yuqing pointed her finger again, pointed to a black area on the top and said.

"It's good to be able to find a location, it's too dangerous for headless flies to roam around in this Dark Cold Immortal Palace. Han Li nodded.

"Speaking of which, the Black Rock Gobi is the safer area among the dozen or so areas. There are no cold beasts like before, and there are no widespread dangers such as storms and cold snaps. Lu Yuqing said.

"Then we were lucky not to be teleported to the danger zone all at once. Han Li said noncommittally.

"Brother Han is not bad, our luck is indeed very good. Lu Yuqing smiled meaningfully and said.

"Oh, what does Miss Lu mean by that?" Han Li asked with a slight raise of his eyebrows.

"Brother Han, do you see this place?" Lu Yuqing pointed his finger to the top of the black Gobi region again, where there was a large yellow area, the most marginal area of the map.

"Is there anything special about this?" Han Li asked after taking one look.

"It's a desert area, we call it the Endless Sand Sea, the end of the Far North of the Cold Realm. Lu Yuqing said.

"So what, could it be that there is some great treasure in this endless sea of sand?" Han Li asked with some confusion.

"I don't know if there are any heavy treasures there, but Brother Han, you already know that in addition to the Cold Realm in the Dark Cold Immortal Mansion, there are actually other realms that have been explored. And the passage from the cold realm to other realms is said to be in this endless sea of sand. Lu Yuqing shook her head and said eloquently.

"Is that true?" Han Li's heart moved when he heard this.

"Nature is true. In fact, the various areas in this cold realm have been almost explored by the monks who have entered the Immortal Mansion over the years, and I originally intended to go to other realms to see it, but I couldn't find the location of this endless sand sea, and I didn't expect that we made a mistake in the teleportation array, and we actually got here by mistake, isn't our luck bad?" Lu Yuqing said excitedly.

"That's good. Without further ado, let's go. Han Li said with a slight twinkle in his eyes, turned around and flew back to the Green Kite Flying Boat.

In the cold realm that has been collected countless times, he has obtained so many treasures, if the others have not been to the border realm, I don't know how many treasures there are.

Lu Yuqing also put away the cyan jade recipe and flew back to the green kite flying boat.

Han Li shot out a burst of cyan light, and the green kite flying boat burst into a flash of spiritual light, and two rows of cyan spirit feathers flashed on both sides of the flying boat, flying forward.

Three days later.

A vast sea of yellow sand appeared in front of Han Li and the others.

As far as the eye can see, the sand and gravel in the sea of sand are pale yellow and crystal clear, reflecting the sunlight of the sky, giving people a dazzling feeling.

At the same time, waves of heat rushed to the face, making the mouth and tongue dry, and the sand sea here was like a furnace.

"Is this here?" Han Li asked, glancing around.

"That's right, it's an endless sea of sand. Lu Yuqing looked at the sea of sand in front of her, her beautiful eyes sparkled, and she seemed to be a little excited.

"This endless sea of sand doesn't look like a good place, does Miss Lu know what dangers are in it?" Han Li didn't rush into it, looking at the sea of sand in front of him, and asked.

"Brother Han has a keen eye, there are indeed a lot of dangers in this. This desert is full of fire poison, and as long as you step into it, you will be slowly poisoned, even the Golden Immortal Monk is not immune. Lu Yuqing smiled slightly and said.

"Fire poison? Probably not just any kind of fire poison. Han Li frowned slightly.

"Indeed, the flow of ordinary elixirs cannot be dissolved at all, only by finding the water spirit land in the desert, with the help of the special water spirit qi in it, the fire poison can be gradually neutralized. If you can't find the land of water spirits in time, the fire poison is too deep, even the Golden Immortal Cultivator may fall into it. Lu Yuqing said with a solemn expression.

"What else?" Han Li asked again.

"In addition to the fire poisoning me, it is rumored that the desert sometimes encounters mirage illusions, which are extremely powerful, and can make people disorient and unable to leave this place. It is precisely because of the two dangers of fire poison and illusion that this endless desert is notorious, and few people who have entered the Immortal Mansion in the past have dared to set foot here. Lu Yuqing continued.

"In this way, this is indeed a dangerous place for life and death. The passage to the other realms is somewhere in this endless desert?" Han Li nodded, then asked.

"The passage is in the depths of the Endless Sand Sea, but Brother Han don't worry, I have a map of the Endless Sand Sea in my hand, as long as we are careful and follow the map, it is not difficult to find the passage. Lu Yuqing took out a jade slip and handed it over.
