Chen Yulou and the others saw six pillars of yellow light suddenly shoot out from the ground around Ou Jingyan, condensing into an unfathomable pattern in mid-air.

A circle of walls of light quickly spread around the pattern, and at the same time, the four corners of the queue also spread through the walls, and soon, the five walls of light joined together, forming an inverted bowl shape that enveloped them inside, and the yellow wall of light flashed a few times before disappearing into the air.

Ou Jingyan slapped her slender slap and smiled at everyone: "Okay, let's sit down and rest! ”

Luo Lao said in surprise: "This is it?"

Ou Jingyan said as a matter of course: "Of course, do you still feel a trace of wind now?"

Luo Lao was stunned for a moment, then untied the scarf around his mouth, and said with a smile: "It's really, there is no wind at all." ”

Chen Yulou and the others stood up and looked around, the black sandstorm had already hit, and the sky, which was still clear just now, instantly darkened.

The trade winds came too fast, and more and more fine sand was swept into the air by the wind, and the surrounding area was shrouded in overwhelming sand and dust, and the visibility became lower and lower, and the wild sand raged, and everywhere was a dull yellow.

However, no matter how violent the sandstorm was, it could not penetrate the slightest within a radius of twenty feet, as if it was blocked by an invisible wall.

In the direction of the storm, the yellow sand slowly formed an arc-shaped sand wall in mid-air, and Chen Yulou and the others knew that the yellow sand was blocked by the light wall that had just disappeared.

There is a sentence in the incantation that Ou Jingyan chanted just now, "Today, an iron siege is erected, and it is not visible in all directions", so the iron siege is invisible, but it really exists, and it is really magical.

"It's too godly, it's too godly, Sister Jingyan, what kind of iron siege array can it stop bullets?" asked Luo Lao with crooked eyes and a twinkle in his eyes to Ou Jingyan.

Ou Jingyan pouted and said: "The iron siege array we have laid out, not to mention the bullets, you can't open it with artillery for a few days and nights." ”

Chen Yulou and Partridge Whistle and the others were speechless, or how to say that Taoist priests who have achieved cultivation are more terrible than the army!

Luo Lao tilted his thigh and said, "Then in this way, if I set up an iron siege formation at the headquarters when I fight in the future, won't it be foolproof?"

Ouyang Fei's crying and laughing voice came, "Safety is no problem, but it's not practical at all, it depends on your brothers to fight, if you win the battle, then your headquarters will be safe at all times." ”

"If you can't win the battle, the only result is that your headquarters will be surrounded by people, and you will starve to death in this iron siege. ”

"Uh...... I'm not a fool, I don't run away after losing the battle, I'm still waiting to be surrounded. Luo Lao tilted his head to look at Ouyang Fei and Mucha who were walking over, and said.

Ou Jingyan explained: "It's useless, once the iron siege array is laid down, the inside and outside will be cut off into two worlds, you can't enter or exit, it's not practical to use in war, if no one lifts it for you, you'll never be able to get out." ”

"Therefore, in addition to being used for defense, this iron siege can also be used to trap people to death or temporarily imprison prisoners, unless the Tao is higher than the person who sets up the formation, otherwise, it can only be unlocked by the person who sets up the formation. ”

After listening to Ou Jingyan's words, Luo Lao Crooked also put out this thought, and lay down against a camel, "I don't know how long this black sandstorm will pass." ”

Ouyang Fei said with a smile: "Don't worry! Usually six to ten hours will pass, I'm afraid I won't be able to set up a tent today, bury the pot to cook, let everyone eat some dry food, and make do with it for the night! Tomorrow the wind should stop." ”

"Yes. ”

Luo Lao responded crookedly, and then instructed Xiao Li to convey the order, Chen Yulou and others also sat down on camels, all looking up to watch the spectacular scene of the black sandstorm, and it is estimated that there is only one in the world to watch the scenery leisurely, and there is no other semicolon.

As time passed, the wind blew more and more fiercely, the wind howled, the sky shook and the earth shook, the surroundings became darker and darker, and the sky and the earth could not be distinguished from the outside of the iron walled city.

This black sandstorm gradually weakened at two or three o'clock in the middle of the night, and by dawn, the sky had cleared, and the tail of the trade wind had passed.

I saw that at this moment, there was a large backlog of yellow sand on the iron siege city, especially the direction of the black sandstorm, the yellow sand has piled up a sand dune under the iron siege city, if the iron siege is lifted at this time, the yellow sand will collapse, enough to bury the people who are close to this side.

"Everyone, lean to the other side, lest one be buried in the sand. After Ouyang Fei greeted, he waved his hand and shot out a wave of mana, shaking all the sand attached to the iron siege city away.

Yellow sand was piled up more than half a foot high around the Iron Walled City, and the Iron Walled City became a small basin, and if it did not do, the sand would be enough to bury half of them.

After the tea, everyone moved to the relatively shallow side of the sand, and then Ouyang Fei and the others lifted the iron siege, and the yellow sand flowed down, only drowning everyone's ankles.

After a little tidying up, Ouyang Fei pointed out the direction, the team started again, Ouyang Fei said in a loud voice: "Brothers, everyone slow down a little, the next water replenishment site is still two days away from here." ”

"To the Exquisite Ancient City, there are only five or six days left, everyone hold on, countless gold and jade treasures are waiting for you to move!"

"Dumped. ”

Whether it was the sergeants under Luo Lao's crooked subordinates, or the various unloading wrestlers, they all shouted loudly, and they were all in good spirits and their morale was greatly boosted.

It is not too easy to go out and fight with Ou Dao Chang and them, in the past, when they went out, which time did they have to lose some brothers? Last time, they poured the Bottle Mountain Tomb, but this time they went into the desert, not to mention the damage, not even a single hair was missing.

If nothing else, let's just say that this black sandstorm, if there is no Ou Dao Chang and them, maybe they will be wiped out, buried in the sea of sand, and become a group of unjust souls in this vast desert.

The crowd marched forward in high spirits, and in less than two days they had traveled nearly a hundred and fifty miles to the next water replenishment point, an oasis that was larger than the last oasis.

Fortunately, they didn't take Hu Bayi's route, because they didn't encounter desert marching ants, otherwise, even if Ouyang Fei and their reaction were timely, they didn't dare to guarantee that they could protect everyone.

After resting in this oasis for one night, and after replenishing the water the next day, we continued to set off, and the next stop was the ruins of the ancient city of Xiye, which was more than three days away.

There was no danger along the way, and the black sandstorm would not break out twice in a short period of time, and after three days, they successfully reached the ruins of the ancient city of Xiye, where the tomb of Prince Gumo was located, but here they encountered some accidents.

"If there is a situation, stop for a moment. When Ouyang Fei and Muxia, who were leading the way, went up a hill, they suddenly fell down with rapid movements, Ouyang Fei waved his hand to the army behind him, and shouted softly.
