Rustling......

A gray figure sped across the dim desert, bringing with it a series of loud voices.

"This place..."

Garten stopped abruptly and looked at the sandy ground in front of him in surprise, which seemed to be the same as before.

I didn't notice it when I first stepped here, but as I got deeper, the strange feeling became stronger and stronger.

Garten shrank the divergent soul power to a radius of ten meters, and his perception suddenly became more acute, and within this range, he could even feel the changes in the air flow caused by the breeze blowing!

However, it is a pity that this state can only be used when it is stationary, otherwise it is definitely a very powerful auxiliary means when used in battle.

Think about it, as long as the enemy just wants to make a move, the muscles in the body subconsciously react, and you will immediately judge the position of the opponent's attack, so as to defend and even attack the opponent's flaws in advance, so that as long as the enemy is not much stronger than yourself, you can win the battle!

"The fire attribute energy contained in the air here is a little thicker than other places, and it also contains a trace of violent characteristics!" The more Garten spoke, the more excited he became, exactly the same situation as he had guessed about the underground passage.

"If it were daytime, the desert would be exposed to the scorching sun, and the fire attribute energy would be unprecedentedly thick, and it would be impossible for anyone to discover that bit of energy leaking from the underground lava sea."

"But at night, it's just the opposite, the fire attribute energy is greatly weakened, and even the temperature drops to the point of cold, the rather violent fire attribute energy becomes more conspicuous, as long as people with strong perception pass by here, they can find this change."

"It's a pity that they only thought that there was an underground passage to the lava layer below, but they didn't know that there was a strange fire in the depths inside!"

Garten couldn't hold back his excitement, and with a laugh, he strode forward, carefully perceiving which location in this sand area had the most fire attribute energy.

In the faint moonlight, Garten's figure flickered rapidly on the desert, like a ghost, and if someone happened to pass by, they would definitely be frightened.

It took only about an hour for Garten to explore the sandy area and emerge in a low-lying location surrounded by several tall sand dunes.

Garten stood in the low-lying center, slowly closed his eyes, shielded his vision, after just a few breaths of adaptation, his perception improved unprecedentedly, plus Gaten only filled the soul power within a radius of ten meters, at this moment, he could even find a trace of vibration in the air.

Garten noticed that just three steps to the left, a very small burst of furious energy was emerging from beneath the sand.

"The underground passage is right down here!" Garten opened his eyes suddenly, and in the dim moonlight, his eyes burst with astonishing brilliance.

In the next moment, Gaten appeared on the sand three steps away on the left, and the pale red fighting qi emerged from his body, forming a pale red energy gauze.

In the shadow of the hand in the sky, a large amount of yellow sand flew on the ground in the distance, and the dust was flying.

Without even taking a breath, Garten's tall figure had already disappeared from the ground, and in its original position, a huge hole appeared in the ground.

After digging five or six meters deep, Garten felt the lightness of his right hand downward, as if piercing a membrane, and actually passed through the sand layer and touched the air again.

"Dig through!"

As soon as this thought came to Garten's mind, he felt the whole person fall downward, and the feeling of weightlessness lasted less than a second, and Garten's boots stepped on the ground, and it was very hard.

A hint of heat hit his face, making Garten uncomfortable, who had been in the cold desert night before.

He took out a moonstone the size of a goose egg from the ring, and the faint white light instantly illuminated the surrounding seven or eight steps.

As soon as he saw the environment in front of him, Garten's eyes couldn't help but narrow, he was now in a somewhat curved passage leading to the underground, with the hole just dug through on his head, and a very smooth black cave wall behind him, and in front of him, it was empty, as long as he took a step forward, he would fall into the underground with no end in sight!

"I just entered this passage, and it gave me such a big shock." Garten looked down the passage, outside the faint light, I don't know how deep the darkness was, and said quietly.

He just stepped on the bend of the passage, and as long as he landed the slightest offset, he would continue to fall in free fall until the end of the unknown depth!

Moreover, the surrounding cave walls are very smooth, as if they have been blasted out by a huge amount of energy, and it is difficult to stabilize the body with the help of force.

"But it doesn't bother me."

The corners of Gateng's mouth hooked a trace of arc, mobilizing the fighting qi in his body to run along a special meridian, and a pair of two-meter-long purple-black illusory eagle wings stretched out from behind.

As soon as the eagle's wings shook, he flew towards the bottom of the passage.

While flying, Garten observed the surrounding environment, and the deeper he went into the passage, the more sure Garten was that this was the place where the Qinglian Earth Heart Fire was born in the original book.

Because this passage is very wide, with a diameter of nearly ten meters, even if you can't fly too fast in the cave, but it is less than ten seconds to a depth of seventy, which has not yet seen the end, and with the smoothness of the surrounding cave walls, it is not a volcanic eruption at all.

"Whew, it's finally coming to an end." Garten retracted his purple cloud wings and landed lightly on the pitch-black rock, he was now a hundred meters deep underground, and this place was very wide, and the light of the moonstone could not illuminate it all.

Garten took out a finger-sized moonstone from the ring, flicked his right hand, and every few steps away, a piece of moonstone fell to the ground, just a few breaths, and the environment of the cave ** was clearly illuminated by the faint white light.

"There are more than a dozen passages here?" Garten, who saw his surroundings clearly, couldn't help but frown, this result was completely unexpected by him.

"Alas, it's troublesome now..."Garten sighed a little depressedly, he thought that if he found the underground passage, he would soon be able to determine the location of the two-headed fire spirit snake, and then wait for the green scales to fully awaken the blue snake three-flower pupil.

Who knows that there are more than a dozen passages below, each passage has to be explored again, and I don't know if there is any danger inside, every step forward must be cautious, the speed can't be raised at all, plus I don't know how deep this passage is, at most explore those two or three passages in one night.

It's not that Gaten is impatient, he can search a wide range outside Stone Desert City, and he is naturally ready to fight for ten days and half a month. He was worried that when he was exploring underground, the hole above was uncovered, and if he stayed too long, it was hard to guarantee that no one would find out.

"Hopefully, there are obvious clues to these holes, allowing me to deduce that those passages would be where the two-headed fire spirit snake is hiding."

After Gaten finished speaking, his figure appeared in front of the dozen or so passages one by one, and he used his powerful soul power to detect the changes in the fire attribute energy inside.

"Among the sixteen passages, eleven of them only have a faint fire attribute energy flowing out, obviously the lava that is the source has solidified into rock, which is not in line with the environment that the two-headed fire spirit snake likes, it can be ruled out!"

A slight smile tugged at the corner of Garten's mouth, and this result would save him a lot of time.

"The other five passages belong to the third channel, the energy is the most violent and the most vigorous, and it is the place where the two-headed fire spirit snake lives with the highest possibility, in this environment with extremely sufficient energy, it is not impossible to grow from a first-order demonic beast to a fourth-order demonic beast."

"As for the four channels, the energy concentration of channel seven is slightly worse, and the other three are a grade lower, so the probability is not high."

With the result, Gaten did not hesitate and directly dodged into the third passage.
