After returning to Taiyi gate, since he knew that someone was watching him outside, he was not busy going out.

First, refine the fire talisman purchased in mingshafang City, and then slowly wait for the opportunity in the door.

After more than half a month, Meng Zhang's waiting opportunity finally came.

Since last night, there has been a strong wind around taiyimen, which has rolled up the yellow sand all over the sky and turned into a huge dust storm sweeping hundreds of miles around.

Endless sand sea, especially the area where taiyimen is located, is a very remote area in the endless sand sea.

It is surrounded by endless desert plains, not even slightly higher mountains, only some sand dunes, not to mention forest vegetation.

As soon as there is a strong wind, there is wind and sand dancing all over the sky. In the field, you can't see your fingers. It's all wind and sand.

Especially when a huge sandstorm is triggered, an oasis without defense can be easily submerged.

All year round, such sandstorm weather will break out from time to time, which has become a major feature of the endless sand sea.

Meng Zhang stood on the small square in front of the sect hall and looked at the scene outside.

Between heaven and earth, a dark, filled with endless yellow sand, almost no gap.

The howling wind makes people tremble at the bottom of their hearts, stirring up the yellow sand in the sky, just like the waves.

At this time, Tian Zhen also came to Meng Zhang.

"There's no problem with the protection array over the sweet water oasis?"

"There are enough spiritual power stored in the spiritual power node, and there are enough spiritual stones to maintain the operation of the array." Tianzhen replied.

In the sweet water oasis, although there is no complete spiritual pulse, there are several spiritual power nodes.

The so-called spiritual pulse is formed by connecting many spiritual power nodes.

In the sweet water oasis, relying on these spiritual nodes, a protective array is deployed.

The Dharma array is a common lower order Dharma array and constant wind array in the endless sand sea.

The defensive power of the Dharma array is not strong, and its function is very single. It is mainly to defend against sandstorm weather.

On weekdays, in order to save spiritual power, the Dharma array is closed.

The Reiki in the Reiki node is also carefully stored.

Even several old taiyimen disciples in the sweet water oasis will not take the initiative to absorb the aura of the spiritual power node. At most, they absorb a small amount of aura scattered in the oasis.

When the sandstorm weather comes, someone will take the initiative to open the Dharma array to prevent the attack of sandstorm.

If the power supply of the power node is not available, there are also some power stones stored in the sweet water oasis, which can be used to drive the Dharma array at the critical moment.

In fact, any oasis in the endless sand sea can take shape. In that oasis, there are generally at least psychic nodes.

Like some large oases outside, there are even complete spiritual veins in the oasis.

Meng Zhang is still very relieved to work in Tianzhen. Since there was no problem with the sweet water oasis, he also returned to the quiet room.

When the sandstorm blew for a long time, Meng Zhang secretly left Taiyi gate without notifying anyone.

Out of caution, Meng Zhang used a Tu Dun Rune at the gate of Taiyi gate and left from the ground.

The distance of using earth Rune to travel underground is generally no more than ten miles.

However, because the surrounding underground is full of very soft floating sand, there is no compact earth rock structure. Meng Zhang's journey underground this time is really much farther than usual.

When the sandstorm broke out, the wild wind made people unstable and even blew people away. In the wind and sand, I can't see my fingers.

Under such weather conditions, even ordinary practitioners in the Qi refining period are very taboo and will not go out easily.

Meng Zhang doesn't believe it. The Chiyu eagle of the Zhao family can also monitor around Taiyi gate in this weather.

After drilling out of the ground, Meng Zhang recognized the direction with his false magic eyes. After successively using the light body magic talisman and divine action magic talisman, Meng Zhang ran towards the target.

Meng Zhang doesn't have to worry about getting lost in the sandstorm. Moreover, with the addition of talisman, he runs very fast.

Meng Zhang is very familiar with the terrain around taiyimen.

He had passed the mine cave more than 100 miles east of taiyimen before.

The sandstorm spread over a wide range, and the area hundreds of miles around should have been greatly affected.

According to Meng Zhang's previous experience, it is possible that this sandstorm will last for several days or even more.

However, Meng Zhang tried his best to speed up the exploration of the mine before the end of the sandstorm.

As it gradually moved away from the area where taiyimen is located, the sandstorm did not weaken at all. But the terrain on the ground began to change slowly.

The ground began to harden and some Gobi began to appear. From time to time, you can see a weathered hill.

When the abandoned baizang clay mine was approaching, the terrain began to become rugged and obviously entered the hilly area. There are more and more hills around.

In Meng Zhang's eyes, some green plants have appeared on the ground, and occasionally there are some low shrubs and cactus.

Under the cover of this sandstorm, Meng Zhang is very close to the abandoned mine.

The mine is backed by a hill hundreds of meters high. The mine is deep underground. It is said that the excavation is very deep.

The exit of the mine is also surrounded by several hills, blocking the exit.

Meng Zhang didn't go in directly from the exit of the mine. Instead, he made a big circle and approached the abandoned mine behind his back.

In this process, Meng Zhang used the false eye to observe the surroundings from time to time to confirm that no one found himself.

In such a sandstorm weather, the monitor should not be there all the time. Even if it is still there, it should not have the eyesight to penetrate the sandstorm.

The ability of the red feather eagle was passed down by the Zhao family, but it has never been heard that this monster has the ability of perspective.

Although sandstorm is a disastrous weather in endless sand sea, it has become Meng Zhang's best cover at this time.

Meng Zhang came to the back wall of the hill where the entrance of the mine cave was located.

The last time he looked around with his broken delusion magic eye, he used the earth escape talisman.

Meng Zhang's body disappeared on the ground and began to walk underground.

Because the underground is all quite compact stone structure, the distance of earth Dunshu talisman passing through the underground is far less than ten miles, and the speed is very slow.

In the end, Meng Zhang penetrated the hills and entered the mine cave.

At the end of Tu Dun, Meng Zhang's body appeared on the ground.

As soon as he appeared, Meng Zhang felt a familiar smell that he had not seen for a long time.
