At a depth of 200 miles in the mountains of Tanggu Mountain, a 500-meter-high black rock cliff shines with a swarthy brilliance under the sun.

This 500-meter-high cliff is actually composed of a whole huge black rock rock, which makes the height of 500 meters look high and steep, which is a bit of a ghostly feeling.

The hardness of the black rock is among the top three on the celestial star.

Therefore, this 500-meter-high black rock mountain, the plants on it are extremely rare, and there are only a few depressions where a few trees of seven or eight meters high grow.

Compared with the big trees in Tanggu Mountain, which are often 100 meters high, the height of these trees is four or five meters, which can be described by the word "weed".

However, a figure, with a three-sè light, like a comet with a long tail, flew around the rock of the black rock a few times before landing directly next to a low tree.

As soon as the light of the three sè was closed, a young monk dressed in a green sè robe came--it was Qian Xing!

Qian Xing looked around the tree, although the tree is only more than four meters high, a little rougher than a large bowl, but the skin of the tree is vertical and horizontal, pimples, you can see that it is very old.

"Okay, that's it, I've finally picked the one I'm satisfied with.

After running for more than a thousand miles, I have not seen such a large hill composed of black robas, only trees growing on it. Only then can I hope to achieve my goal. ”

Qian Xing said with satisfaction.

The golden light flashed in Lao Qian's hand, and the golden snake flying sword was already in his hand. A green sword ray, stretched out the tip of the sword in an instant, as long as three meters.

Lao Qian immediately raised his hand and cut it down two meters next to the root of the tree!

There was a loud "choking" sound, the blue light flashed, the black sè rock fragments splashed randomly, and the hard black martial rock was cut out of a two-meter-deep gap!

This black rock is really hard. I poured the sword light of the Qing Ning Sword Technique, and condensed it into a sword. It was only cut to a depth of two meters!

Then, the old money was on the side of the crack just now. He slashed three swords in a row, a total of four times, and the three-meter-long green sword mang, cut the ground rock out of a square square.

And then. Lao Qian put away his flying sword, his hands glowed with green sè, and he inserted it into the Quartet Black Martial Rock Block!

In an instant, it gave people the impression that it was not two arms that were inserted down, but the momentum of a huge shovel of a 100-ton excavator.

"Boom!"

Most of Lao Qian's two arms were submerged in the hard black martial rock, all the way to above the elbow!

"Up!"

Old money let out a wild shout again!

"Squeak, squeak. Squeak"

There was a tooth-aching grinding sound. One piece is two meters long and two meters wide. The two-meter-deep four-square-block black rock was pulled up by Lao Qian, and a square and two-meter-long hole appeared on the mountain.

"Peng!" Old Qian put the upholstered rock to the side. He looked at the wall of the pit near the tree and nodded.

Lao Qian is looking at the root system of this tree, which can penetrate the root system of the incomparably hard black rock!

The green sword soared, and once again along the square pit wall, looking downward!

"Bang dang! bang dang!"

It's like a miner, going crazy, wielding tools and digging rocks!

As the two-meter-long square rocks were moved out by Lao Qian and placed next to the pit, the depth of this two-meter-long square pit gradually extended.

Every time the depth of the pit deepened, Lao Qian looked at the pit wall near the tree and made an exclamatory sound.

"I really didn't expect that the roots of this tree can penetrate such a thick black martial rock! What kind of liliang is this, so that the roots of the tree have such an indestructible tenacity?"

Finally, when the depth of the pit reached a depth of five hundred meters, Lao Qian was already so shocked that he couldn't speak!

The roots of this tree actually penetrated the black rock at a depth of 500 meters, and knew the location of the foundation that was deep enough to be full of earth and water.

Although after more than 500 meters, the layers of trekking in the hard black rock, the further down, the smaller the diameter of the root system, the diameter of the root system at the bottom does not need to be much thicker than a hair!

However, it was these roots, which were only slightly thicker than a hair, that penetrated the five hundred meters of black rock!

Nutrients have been delivered to the trees on the top of the 500-meter Black Rock Mountain! Let this tree stand proudly and become a beautiful scenery on the bare and huge Black Rock Mountain!

A green glow slowly lifted Qian Xing along the cave wall, and Qian Xing's palm slowly stroked the thin tree roots embedded in the cave wall.

Qingguang slowly rose to the top of the cave, and then, slowly, Xiangxia landed.

The palms of the money-making hands have always been caressing the roots of these 500-meter hard black martial rocks, trying to feel their strength!

The sun went down, and the entire area around the Black Rock Mountain was plunged into darkness that was darker than the Black Rock itself.

However, in this pit more than 500 meters deep, above a ball of green light, a lonely figure was still slowly descending and rising!

A ray of fish-belly-white dawn tore through the dark and dull sky, and this green light still held the lonely figure, rising and landing!

After Ugly flew away in search of food, he returned to the edge of the deep pit, silently watching the boss, touching the tiny roots on the pit wall over and over again.

It rained in the sky, rain for a day and a night, and the rain poured in from the mouth of the pit like a stream, and when the rain stopped, the water in the pit had reached more than 20 meters

However, the light of this green sè still slowly sank into the stagnant water more than 20 meters deep.

Qian Xing didn't activate the Dao Law shield, and let the stagnant water drown himself.

As long as you reach the innate peak, the pores of your whole body can breathe air, and ordinary water can no longer drown a monk above the peak of Qi cultivation!

Under the soak of a large amount of rainwater, Lao Qian felt that the thin roots of the tree that his palm touched were actually passed with a burst of joy!

Usually due to being deeply rooted in the rocks, even if there is heavy rain, immersed in the cracks of the rocks, the water absorbed by the roots is not much, so much rain, suddenly soaking the roots in it, naturally let the emotions of the roots, there was a fluctuation, felt by the old money!
