For the next few days, the Purple Light Team did not continue to advance, but set up camp by the lake where the Thousand Tooth Badge lived. This was originally the territory of the Thousand Tooth Chapter, and with the terrifying combat power of that beast, unless there were a very few unknown beasts or fierce beasts, the truly powerful beasts would not come.

In this way, there are hardly any worries in terms of safety, and as for the reason for the temporary stay, it is naturally to allow Yun Ji to recover.

Her injuries are indeed not light, but there are enough healing medicines, coupled with Qin Yan, a holy hand of medical Dao, she will definitely be able to fully recover in three or five days.

The next few days were a rare and comfortable time.

"There's no water again."

Li Guangyuan shook the empty water bladder, and was about to find the golden dragon to take him to find the water source: "Golden dragon! The lake water is poisonous and cannot be drunk! ”

Suddenly!

He saw that the golden dragon actually ran to the lake and drank violently at a clear lake.

This lake was originally the territory of the Thousand Tooth Chapter, as the most difficult type of beast to deal with, the Thousand Tooth not only has dozens of tentacles with amazing attack power, but also a bit like a cuttlefish, it will spit out a poison that is extremely lethal to animals.

This is also the reason why there are so many aquatic plants in the lake, but there are no fish in sight: I am afraid that the creatures in the entire lake would have died long ago, otherwise the Thousand Tooth Chapter would not have gone to the land to find food.

Seeing this scene, Qin Yan smiled and said, "There's nothing to worry about, don't forget, the golden dragon is invincible, and the toxins in the lake are useless to it." ”

"yes, I forgot." Li Guangyuan smiled.

The Purple Gold Jiao itself does not have venom glands, but it has the ability to be invincible to all poisons, and it has already shown its innate ability in this regard in the battle with the Black Head Poisonous Python.

"Hiss......" Jin Long heard Li Guangyuan's shout, turned his head and hissed at Qin Yan.

"What does it do?" Li Guangyuan was stunned.

"Something may have been discovered."

Qin Yanfei also ran over, and everyone also ran towards the golden dragon when they heard the news.

The golden dragon couldn't speak, but he learned to express his meaning with his actions, and through his movements, he had more and more tacit understanding with it to Qin Yan, and quickly picked up the lake and Tian Tian.

"The lake water is no longer toxic!" Qin Yan was a little surprised.

"How could it be ......"

"It's not surprising."

Qin Yan thought for a while, and then smiled: "There are many kinds of toxins, some are slow, some are urgent, some will not deteriorate if they are stored for thousands of years, and some toxins will naturally decompose after a certain period of time once they are released...... It is likely that the toxin secreted by the thousand teeth is the one that can be decomposed. Now that it has left the lake, no new venom has been released, and the previous venom has slowly broken down. ”

At this time, Feng Ziyin shook her head and denied his words, and frowned: "You forgot a question, the venom glands of the Thousand Tooth Chapter are valuable. ”

What do you mean?

If the toxin leaves the body for a period of time, it will naturally break down the toxin and become invalid, then the venom glands of the thousand teeth have no value.

Because, in the process of leaving the Flood Forest Plains with its poison glands, the poison glands that have lost their vitality will decompose and fail halfway.

In other words, although Qin Yan's analysis of the non-toxic problem of the lake water is very organized, it is all based on the premise that the toxins of the thousand tooth will naturally decompose, and in fact, the toxins of the thousand tooth chapter will not decompose quickly - so, what is the reason for the original poisonous lake water toxicity to disappear in just two days?

"Unless ......," Li Guangyuan's eyes lit up.

"There's something in the lake that cleanses toxins!" Qin Yan took over the conversation.

"Will it be dangerous?" From Qin Yan's eyes, everyone already knew what he wanted to do.

"There's never going to be a second thousand tooth in there, right?"

Qin Yan smiled and said, "As for other creatures, it must be impossible. The weak can't survive here, and the strong can't even more so than the strong, one mountain can't tolerate two tigers, and it's impossible for the Thousand Tooth Seal to let another creature compete with it in the lake. ”

At the level of the Flood Desolation Beast, the division of territory is extremely strict, so it is certain that there cannot be other powerful beasts in this lake.

"I'll go too!" Feng Ziyin volunteered.

"It's not dangerous anyway, what are you going to do?" Qin Yan politely refused.

"Since there is no danger, why can't I go?" Feng Ziyin had no intention of backing down.

"Little sister, when you enter the water, your clothes will stick to your body...... You shouldn't be using this method to seduce my little Langjun, right? ”

"How can I!"

"There is no best."

"Humph!"

As a result, Feng Ziyin naturally no longer asked to go with her, and the requests of others were also refused, and Qin Yan immediately plunged into the lake with a fierce son.

This lake is far from being as big as the lake that I just fell into when I came to the Immortal Martial Realm, but it is a lake that is roughly half-moon shaped, and the area is more than ten square kilometers. Even if the water is excellent for an ordinary person, it is impossible to search for such a large lake.

Qin Yan is not an ordinary person, just like the speed of the Thousand Tooth Seal is extremely fast in the water, and the speed will slow down when it reaches the shore, this kind of reduction is only relative.

True Qi was infused into his legs and arms, and he shuttled like a swordfish, and his speed was definitely no less than 200 kilometers per hour.

In addition, the water of the lake is extremely clear, and he can see at a glance with his eyesight, the situation is two hundred meters away, so the search speed is not slow.

Really.

As expected, there are no animals in the lake except for lush aquatic plants, whether large fish or small fish and shrimp.

He swam quickly along the bottom of the lake, turning back every few hundred meters, and began a seamless carpet search.

Half an hour......

An hour......

Occasionally, some medicinal plants have been found, and even two aquatic plants of great value have been found, but the medicinal effect does not match the target to be sought.

Because he started to search from the edge of the lake side, he started to search in a turnaround way, so the area he searched at the beginning was in the outer circle of the lake.

After two hours of careful searching, more than a third of the bottom of the lake, he finally approached the central area of the lake.

At this time, his gaze fell on a large patch of aquatic plants.

Is that......

He quickly recognized the origin of the water weed, the Buddha palm vine.

The area of this Buddha palm vine was the size of a football field, but he was not excited. It is true that this plant has an excellent detoxification effect, but there are many medicinal materials with similar effects in the Xianwu Realm, and the most valuable medicinal materials in this world are always used to improve cultivation, replenish true qi, and treat serious injuries.

Therefore, the value of the Buddha palm vine is not low, there is a collection value, but it is definitely not priceless, if there are too many of them, he is really too lazy to take them all.

Just as he was about to leave and ask everyone what they meant, whether they wanted to collect these Buddha palm vines, he suddenly remembered the living conditions of this plant.

Buddha palm vine is an aquatic plant and has high requirements for the growth environment.

Among them, this lake also has all kinds of environments, but there is one thing that he can't understand - the Buddha palm vine must live in the water with a relatively low temperature.

Although the water temperature here is not high, it is definitely not low, it should be about 20 degrees, and the water area where the Buddha palm vine lives, the temperature must be around zero degrees.

Why can they survive here?

Don't......

Qin Yan thought about it, dived into the bottom of the lake again, pulled out the Great Xia Dragon Bird Knife, and began to dig to the bottom of the lake: the temperature of the lake water did not meet the requirements of the living environment of the Buddha palm vine, and the problem must have come from under the bottom of the lake.

A large chunk of silt was dug up, and the originally clear lake water became turbid, and even with Qin Yan's eyesight, there was no way to see what was below. However, when the silt was dug up, he could clearly feel that the temperature below was significantly lower than that of the lake.

Wrong!

It's not just about the temperature, it's about the cold!

Then he dug for a while, but he didn't find out what the problem was, and he immediately had an idea in his heart: the area where the Buddha's palm vine grows is a place, about the size of a football field, and the key area is almost a regular circle, which means that the cold air is radiating from the central area to the surrounding area into a circle.

Thinking of this, he first surfaced on the surface of the lake to change his breath, and then roughly estimated the most central position of this area, and began to dig down again.

Because he was afraid of damaging what might exist below, he didn't dare to use his true qi to bombard, so he could only use the Great Xia Dragon Sparrow Knife as a shovel to dig slowly.

However, the strength of the cold air escaping from the silt makes it possible to determine the exact direction of the excavation.

There was a clang.

When the digging was about fifteen or sixteen meters, and the cold air had reached a very strong level, the tip of the knife suddenly hit something very hard.

Because there was too much silt to interfere with his vision, he didn't know what it was, so he could only use the tip of his knife to test it around little by little.

It is estimated that after moving to the side for about half a meter, the tip of the knife fell into the mud again, and it was initially estimated that it was a piece of something, about a meter in circumference. Again the thickness was tested along the edges, and the thickness of this thing should be thirty or forty centimeters, in an irregular oblate shape.

What is this thing?

Because of the mud below, the line of sight is greatly restricted, and there are no people in sight half a meter away from the dirty lake.

He grabbed the corner of the thing and dived to the surface of the lake.

Get Extremely Cold!

At the moment when he caught that thing, he hurried to a cold cold air, which spread to his body along the place of contact, and with his strength, he couldn't help but shiver. At the same time, he found that this thing was very heavy, according to the volume just tested, even if it was a thousand kilograms of steel at most, but this thing was at least three or four tons.

Soon, he dragged the thing out of the muddy waters, and only then did he see what he was holding.

The next moment, he was completely dumbfounded.

Twenty minutes later, this irregular circle, almost a meter in diameter, and of varying thickness, appeared on the shore next to the lake.

In the area it touched, the weeds on the ground froze one after another, and even the surrounding air was condensed into ice crystals, showing a thick white gas.

Extremely cold!

It is dark blue to almost black throughout, resembling the crystalline appearance of ice, a bit like glass or diamonds with added color.

However, no one in the scene would think that it was a diamond, and no diamond would have such an amazing cold that everyone could recognize what it was, and because of that, everyone would remain motionless on the spot......
