There is one thing that Yi Han doesn't know, that is, Xu Fu, as a pre-Qin Qi practitioner, knows a little bit of the way of formation, which is normal.

For Yi Han, he had also studied the formation in his first life, although he was not proficient, but the ordinary formation could not stop him.

In front of the cave, after Yi Han's careful observation, he already knew what kind of formation this was, and he also knew how to crack it.

"The Void Array, it's the Void Array!"

The Void Array, as the name suggests, is a formation that can isolate the space of one side, and no matter what changes occur outside the array, the space of the array will not be affected.

That's why, thousands of years ago, the earth's crust collapsed and the cave was flooded without being affected at all.

Yi Han stood in front of the cave and carefully turned around outside the cave, if he wanted to break through the Void Array, he only needed to find the eye of the big array.

What Yi Han is most worried about now is that if the array eye is in the cave, it will be troublesome, because as far as Yi Han knows, there are internal and external formations.

The inner array, that is, means that the eye of the array is in the array, and the outer array is outside, don't underestimate the difference between inside and outside, the two are very different, and there is a big difference when it comes to cracking.

It's like a locked door, you stand outside the door, and if you want to open the door, you can only open it if you find the key, but if the door is locked from the other side, then even if you have the key, it's useless.

The inner and outer formations of the Void Array, this is the reason, if it is an outer formation, the eye of the formation is outside the cave, Yi Han can easily break the formation, but if the eye of the formation is in the formation, then it can only be broken by violence.

Yi Han looked left and right around the cave, and finally found something strange on the left side of the cave, there was a stone statue there, it was gluttonous, if the guess was correct, under the gluttonous stone statue, it was the eye of the air array.

"Is this the eye of the array?" Yi Han stepped forward and removed the gluttonous stone statue, only to see that under the stone statue, there was a piece of jade crystal, and the jade crystal released a soft light, but the jade crystal was a little dim, as if it had lost its luster.

Jade crystal, Yi Han is naturally no stranger, this is an indispensable essence stone for the cultivation of monks, jade crystal contains the aura of heaven and earth, which can provide aura cultivation for monks, much faster than the monks themselves to accept the aura of heaven and earth.

Generally speaking, according to the intensity of the aura, this kind of essence stone containing aura, can be divided into three categories, from less to more, namely jade, jade crystal, chalcedony, with the improvement of quality, the purer and thicker the aura contained in it.

It seems that this Xu Fu is not simple! he can get Yujing, in the first life, in the Spring and Autumn Period, Yi Han was also a qi practitioner, but at that time, Yujing was also a rare good thing, very rare.

Bending down, Yi Han picked up Yujing, only to see that the moment Yujing was picked up by Yi Han, the surrounding lake water suddenly surged, the air array was broken, and the surrounding lake water instantly poured into the cave.

"Oops! Elixir ......" Yi Han scolded secretly, the air array was broken, the lake water was poured in, and the elixir in the cave was bound to be affected, if the elixir was destroyed, then all the previous efforts would not be in vain.

Due to the water of the lake, everything in the cave was washed out of shape, and the stone tables and stone benches fell to the ground in a mess, and when Yi Han walked into the cave, his eyes were straight.

Everything in front of him was not what he thought, the elixir was still there, and he had not received any damage.

Gather your eyes and look around, only to see a corner of the cave, a small green tree, swaying, exuding a stream of glow, such as the clouds on the horizon, brilliant and dazzling, every time the small tree shakes once, the lake around it, it retreats a point. In the small tree, an isolated space is formed around it.

"This is?" Yi Han was stunned.

The small tree is about two meters high, straight as a pine, at first glance, it really looks like a pine tree, with green leaves, flashing with mist, all clearly indicating that this is not a pine tree.

Yi Han approached step by step, his eyes were straight, although he didn't know what kind of tree this little tree in front of him was, but with the experience of the ninth world, there was a voice in his head telling Yi Han that this little tree was not simple, it was definitely a treasure.

What Yi Han didn't know was that at the moment when the Aerial Array was cracked, the water monger beast on the shore suddenly stopped moving, and it looked towards the lake suspiciously.

In the next second, the water otter beast suddenly roared, and the roar was full of monstrous rage, it abandoned Yuan Feng and the others, and rushed towards the lake.

Seeing this, Yuan Feng shouted, "Rocket!"

At this time, the water otter beast was already scarred, how could Yuan Feng let it return to the lake, in that case, wouldn't the previous fight be wasted?

Not far away, a soldier carrying a bazooka and his sight was facing the otter beast, only to hear a 'bang!', a flash of fire rushed out, followed by a loud bang, and exploded on the shore of the lake.

When everything was calm and the water monger beast lost its trace, Yuan Feng and the others rushed to the lake, and what caught their eyes was a pool of blood, as well as some flesh and blood blurred scale armor.

Is the water monger dead? Yuan Feng was not sure, judging from the situation by the lake, even if he was not dead, he was seriously injured.

Li Xuelin and the others cautiously walked to the lakeside, "Did you escape?"

Yuan Feng frowned slightly, and in his dark eyes, there was a look of pity, whether the otter beast was alive or dead, he didn't know, but Yuan Feng had a hunch that the otter beast might not be dead.

"Teacher, what now? The Otter Beast escapes, it's underwater, we ......"

Yuan Feng said: "Don't worry, maybe the water otter beast is dead, even if it doesn't die, even if it hides underwater, it's fine, I have my own way to deal with it." ”

At the same time as Yuan Feng spoke, a soldier walked over, only to see that he was holding something similar to a car in his hand, only to hear Yuan Feng continue: "This underwater probe can clearly detect everything underwater, whether the beast is dead or not, we will soon know." ”

Yuan Feng put the detector into the water and connected it to the computer at the same time, and soon everything in the lake was clearly displayed on the computer.

But what everyone didn't know was that at this time, there was a big battle at the bottom of the lake.

In the cave, after Yi Han found the small tree, he found that he didn't know what it was at all, and Rao had the memory of the eighth life, and he had never seen it.

It's said to be an elixir, it's not like it, it's clearly a tree, but if it's a tree, it exudes a pungent medicinal fragrance, and Yi Han has the urge to go up and take a bite, this fragrance is too charming.

What surprised Yi Han even more was that there were still fruits on this tree, counting them carefully, there were eleven in total, and although these eleven fruits were the same in size, they were not the same in color.

The pungent aroma is emitted by these eleven fruits, at this time, Yi Han suddenly recalled one thing, that is, in the first life, on Huaguo Mountain, Yi Han had also smelled a similar aroma, giving Yi Han a feeling that it was not much different from the current aroma.
