Under the ice wall, there are staggered plants growing there, swaying slightly in the wind.

Xiao Mo counted, one, two, three...... There are seventeen plants in total.

According to Zuo Xiutong's method, the water system spirit grass should be held in a gold box, the so-called gold is born of water, less yin qi, warm and moist, and it is the most suitable for the blooming of water system spirit grass.

Because Xiao Mo didn't bring metal utensils, all these Xuanxue grasses were stored with Zuo Xiutong first, and after returning to the school palace, the two of them divided them together according to the income from this trip.

After collecting all the Xuanxue grass on the ice wall, Xiao Mo and Zuo Xiutong couldn't help but smile at each other, and they both felt a trace of joy.

Sure enough, the greater the risk, the greater the benefit, not such a place, where to find seventeen or eighteen Xuanxue grasses, just these Xuanxue grasses, coupled with some other auxiliary medicines, the refined Xuanxue Pill is enough for Yu Qing Medicine to use for a long time.

Of course, these Xuanxue grasses are not Xiao Mo's alone, but it doesn't matter, the two of them enter the Lingwu Mountain Range, and all the spirit grasses they find in the end will be shared together, Xiao Mo only needs to divide some of the other spirit grasses he obtains in exchange for the remaining half of the Xuanxue grass, which is not a big problem.

After all, Xuanxue Pill is not a common pill, it is more out of the door, and it can be used by people who practice Yin attribute exercises such as 'Tracing Yin Xuanxue Gong', presumably, Zuo Xiutong will be happy to exchange this kind of partial herb for other conventional spirit grasses.

After collecting the Xuanxue Grass, Xiao Mo and Zuo Xiutong turned around and collected the materials on the bloody stone ape that they had killed.

This time, the harvest is not only seventeen green-level low-level spirit grass Xuanxue grass, but also this two-star extreme mutation beast Storm Blood Stone Ape, when it reaches above the two-star beast, the materials are of great value, not to mention the two-star extreme mutation beast, some of the materials on this blood stone ape are also a lot of materials.

It wasn't until these materials were collected that Xiao Mo and Zuo Xiutong continued to walk along the road below the ice wall towards the depths.

Since such a large amount of Xuanxue grass can be found just on the periphery of this mountain stream, I am afraid that there are more precious things in the depths, Xiao Mo and Zuo Xiutong, they tasted the sweetness, and naturally they were unwilling to give up.

Fortunately, they are brave and bold, and ordinary people have seen the terrifying two-star extreme mutated beast of the Stormy Stone Ape on the periphery of the mountain stream, and they are afraid that they will not be able to avoid it, where do they dare to continue to go deeper.

Cautiously, he walked all the way inward along the ice wall, and sure enough, the bottom of this stone stream was really extraordinary, and then, Xiao Mo and Zuo Xiutong faced several waves of mutated fierce beasts in a row, all of them were two-star high-level, and even two-star extreme fierce beasts, and most importantly, they were all mutated, and there were almost no ordinary ones.

The strength of these mutated fierce beasts is not worse than the bloody stone ape encountered by Xiao Mo and Zuo Xiutong before, but under the joint attack of Xiao Mo and Zuo Xiutong, they still quickly hated it.

With the continuous occurrence of battles, the two of them have more and more tacit understanding, often the other party can understand the meaning of the other party with a look, and it is easier and easier to deal with those two-star fierce beasts, after all, neither of them is mortal, Xiao Mo needless to say, Zuo Xiutong alone can be comparable to the average Qiwu Realm early stage monk.

And as the battle continued, Xiao Mo finally understood what the bronze arrow that Zuo Xiutong had shot the bloody stone ape before was, it was a special attack device, and Zuo Xiutong named it the 'Divine Machine Crossbow'.

The Shenji crossbow is very ordinary, that is, it is made of refined black copper, but the firing power is very large, but the material used to make the Shenji crossbow arrow is not ordinary, it is a rare material called 'mixed yuan silver copper', and the biggest characteristic of mixed yuan silver and copper is - armor piercing.

The arrows mixed with this material can easily shoot through those powerful shields, and the hard scales and armor on some fierce beasts are a very rare kind of arrows, and they are naturally not a problem against the petrified skin on the blood stone ape.

To be honest, if it weren't for the fact that the bloody stone ape was really difficult, Zuo Xiutong would be reluctant to use the Divine Machine crossbow arrow to deal with it, this kind of material is rare, and she doesn't have much on her, but fortunately, these things can also be recycled, as long as they are not directly damaged, the others can be collected and barely used.

Of course, if you use it once, there will be a little bit of damage, and the power will definitely be much worse if you use it again, how do you look at it, it is still a little distressing.

"Why are there so many mutated beasts in this place?"

Walking and walking, Xiao Mo and Zuo Xiutong couldn't help frowning, seeing that something was wrong.

If the two of them met one by chance, or even two mutated beasts, then that's it, after all, this kind of thing is not uncommon, some powerful beasts, for various reasons, or the bloodline mutated, or affected by some kind of environment, and even maybe just swallowed a special herb, and the mutation is very normal.

However, this probability is still very rare, and among hundreds or thousands of fierce beasts, there may only be one mutated fierce beast.

But at the bottom of this mountain stream, so far, what Xiao Mo and Zuo Xiutong have found is almost all mutated fierce beasts, and ordinary fierce beasts are nowhere to be found, which is a bit weird.

Xiao Mo's eyes flickered, and he said, "Senior Sister Zuo, do you still remember that when we were on the mountain stream before, we saw a blood-colored mist drifting by...... At that time, I felt that this area was a little unusual. ”

"Hmm. ”

Xiao Mo said this, Zuo Xiutong also reacted, nodded and said: "Yes, I also felt a palpitation before, it seems that there is danger watching in secret, but I can't find the source of the danger, and now it seems that it should be in this mountain stream." Next, we have to be careful, there may be some kind of change here that we don't know about, be careful to make the ship of ten thousand years. ”

"Yes. Senior sister ......"

When the two of them heard this, their expressions were a little more solemn, although they were still moving forward, but their speed was much slower, and their bodies were already full of luck, and they didn't dare to slack off.

"Whew!"

Suddenly, a fiery red light shot from the rock wall on one side to Xiao Mo, who was walking on the left, Xiao Mo's figure flashed, and the aurora body method was launched, directly avoiding this blow, he was already vigilant, the red light flashed in his sleeve, and the Xuanhuo Ding rushed up, just colliding with the fiery red light.

"Smack!"

The speed of the Xuanhuo Ding was so fast, after infusing the heart vitality, the strength was ten thousand, and it collided with the fiery red light, and suddenly "poof", the fiery red light suddenly paused, and then fell to the ground, writhed on the ground a few times, and then did not move.

Xiao Mo walked over, did not approach immediately, but cautiously launched four or five more Ice Xuan Fingers, and after making sure that it was dead, he stepped forward and watched carefully.

I saw that this was a small red snake, and the body of the little snake was flowing with a blood-like light, which seemed to be extremely dangerous.

"Fire Eater Serpent!"

Seeing this, Xiao Mo and Zuo Xiutong couldn't help but change their faces slightly, recognizing the origin of this little snake.

The Fire Devouring Spirit Snake makes a living by devouring some fire essences, and its speed is fast, but it is not powerful, but this Fire Devouring Spirit Snake is obviously extraordinary, and the blood in its body shows a gem-like color, although it has not mutated, it is on the verge of mutation.

Xiao Mo and Zuo Xiutong glanced at each other, and a guess in their hearts couldn't help but be crazy.

"Could it be that the reason why there are so many mutated beasts here is because there is a special area under this mountain stream where a large number of fierce beasts can evolve and mutate?"

"So, where is that area?"

There is no doubt that the matter has come to this point, if only one or two mutated beasts are found, Xiao Mo and Zuo Xiutong will not be surprised, but they encounter ten heads and eight heads, but there are very few ordinary fierce beasts, and even if there are, they are on the verge of mutation, so they can't help but let the two of them guess.

Or, they were extremely unlucky, and they were able to meet a mutated beast, but this is almost impossible, how can it be that all the mutated beasts in the world are gathered in this mountain stream.

Or, there is a place in this mountain stream that can mutate ordinary fierce beasts, which is even more weird, on the contrary, it also arouses the interest of Xiao Mo and Zuo Xiutong even more, there is such a secret place, how can the two of them not be able to explore it? Even if they encounter danger, they can't take care of it.

It is said that the greater the risk, the greater the return, but the reverse sentence is also true, the greater the return, the greater the risk.

I also understand that in just this short period of time, Xiao Mo and Zuo Xiutong have successively encountered the two-star extreme mutated fierce beast Storm Blood Stone Ape, the fierce beast devouring fire spirit snake in the two-star high-level mutation, and a large number of other fierce beasts that have mutated or mutated, what is at the bottom of this mountain stream, no one can say?

Will there be a three-star low-level mutant beast in the end, or even a three-star mid-level and three-star high-level mutant beast? Xiao Mo, Zuo Xiutong didn't know.

With the strength of the two of them, for the time being, it is dangerous to deal with ordinary two-star extreme beasts, and to deal with three-star low-level is to find death, and three-star mid-level is not a level they can resist...... It's just that, as the saying goes, curiosity kills cats, and they don't want to give up the opportunity to explore the secrets of this place, so they still go all the way.
