"Uh-"

The loud noise was so shocking that everyone present was startled and at the same time, tinnitus appeared in their ears.

Wu Liang just happened to have his back facing the direction of the loud noise. When he turned around and looked around, he saw nothing. He had to immediately ask the person next to him: "What happened just now?"

"Sir, it's thunder!"

Yu Ji shouted at the top of his lungs with a shocked look on his face, "I just saw a huge thunder and lightning like a giant ax suddenly falling from the sky and hitting the sinkhole!"

"Brother Youcai, it is indeed a thunder and lightning. Not only is the thunder and lightning huge, but it is also an extremely rare purple color. I have never seen such a huge thunder and lightning at such a close distance in my life. The power must be very terrifying. Fortunately, it only hit the target.

Inside the sinkhole!"

Zhuge Liang also came to his senses and shouted to Wu Liang at the same time.

It's not that these two people are far away from Wu Liang, but they are both in a state of tinnitus at the moment, and they will unconsciously raise their voices when talking.

Even Wu Liang is like this, but he can't feel it.

"Thunder and lightning?"

Wu Liang looked suspicious, "Are you sure it's not a rolling mine?"

"It's definitely not the rolling land mines that are common in this place. This is a thunder that really fell from the sky. When it fell, it was like a sharp blade tearing open the sky!"

Yu Ji shouted again, "I can see it for real, I can't fake it!"

"The old gentleman is right, we have seen it too!"

Many soldiers of the Hu army who had witnessed the scene just now also agreed.

"Then this should be a rare phenomenon in the secret realm..."

Wu Liang pondered.

These days they are living in a secret realm. Although they are at a loss as to the strange poison and the inheritance of "Bian Que", they have basically figured out the environment in the secret realm.

Except for the frequent rolling mines and the always dark sky, this secret place is basically not affected by the outside climate.

After all, the Hu army would leave the secret realm in search of food every few days, so they could compare the situation inside and outside the secret realm at any time.

Sometimes the sky is clear outside, and the sun heats up the earth and rocks on the ground, but it is still dark here, and the temperature and humidity do not change at all.

Sometimes the sea breeze blows outside, and it rains heavily. The river and sea water can set off huge waves several meters high, but here you can't feel any wind or rain, and it has become the most stable haven.

In short.

The environment and climate here are extremely stable, and wind, rain, lightning, and sunshine seem to have nothing to do with this secret place.

But just now, thunder suddenly fell here, and it was an extremely rare purple thunder...

As far as Wu Liang knows.

Not only purple lightning exists in nature, but also reddish-brown, green, yellow... and other special lightnings also appear occasionally. However, the journey of these lightnings requires more stringent conditions. According to later research, this kind of colored lightning

In fact, it is mainly the result of physical and chemical changes.

This kind of purple lightning should be related to ozone.

However, it remains to be discussed whether the purple lightning that everyone saw just now is related to this.

There is another detail that is puzzling.

The tiankeng struck by this purple lightning is the lowest place in the secret realm. According to the characteristics of lightning, shouldn't it hit the holy mountain that is almost connected to the tiankeng?

"If it's a vision..."

Wu Liang suddenly stood up and ran quickly to the sinkhole dozens of meters away.

Thinking about it, they have been in this secret realm for nearly a month. They patrol the secret realm almost every day and never let go of any clues. However, they still have found nothing until now. Perhaps it is because the secrets of this secret realm are usually not known at all.

It will appear, and it will only appear together when a vision occurs.

"Son!"

Seeing that Wu Liang was behaving abnormally, everyone in the Hu army also hurriedly chased after him.

Arriving at the edge of the tiankeng, Wu Liang and everyone looked down at the bottom of the tiankeng.

However, the bottom of the sinkhole was still pitch black at this moment, and the broken pottery pots could still be vaguely seen. There were no obvious changes in these, as if the lightning was just a formality and did not affect anything.

"How come there is no change?"

Wu Liang couldn't help but feel a little disappointed, and then he looked up at the sky, which was not gloomier than before.

The sky did not change, and there were no thunderclouds in the sky, so didn't that lightning appear out of thin air?

With this in mind, Wu Liang was still hesitating whether to lead his people down to the bottom of the tiankeng to take a closer look at the traces left by the lightning. After all, if another lightning bolt like that struck them when they went down to the tiankeng, it would be worse than a rolling land mine.

It's much scarier, I'm afraid everyone will be wiped out.

Just then.

"Rumble—!"

The ground shook violently.

Wu Liang was standing at the front. He stumbled unprepared and apparently rolled directly into the sinkhole.

"Son!"

Dian Wei quickly pulled him back with quick eyes and hands.

Everyone in the Hu army also quickly pulled together and retreated. At least no one had any accidents.

However, just when they could barely stabilize their bodies.

"Rumble—!"

A more violent shock struck again.

The amplitude of this earthquake was obviously stronger than the previous ones, and it lasted longer. Even if the people of the Hu army were tightly together, they fell into one piece uncontrollably.

Not only that, even the gravel on the ground began to roll around.

The only ones that are still stable are the few boulders that Hua Tuo used to build the stone house, which are at least tens or hundreds of tons. Even so, it can still be seen that the boulders have shifted slightly.

"Quick, take Divine Doctor Hua with you and we'll move to the open area over there as soon as possible!"

When the vibration slowed down slightly, Wu Liang immediately gave the order.

Although he didn't know what would happen next, the safest thing to do right now was undoubtedly to stay away from these boulders and gravel.

"promise!"

The Hu army quickly took action.

Several people rushed over to lift up Hua Tuo, who was having difficulty moving, and rushed towards the area designated by Wu Liang. Others, ignoring the tents and supplies, supported each other and moved at an extremely fast speed.

So wait until they have just completely transferred.

"Bah——!!!"

Another loud noise suddenly sounded.

This time Wu Liang finally saw clearly what happened.

I saw a huge lightning bolt several meters wide that suddenly tore through the haze in the sky like a purple dragon, then instantly crossed the sky and crashed into the sinkhole.

The picture was so spectacular and majestic.

Anyone who looks at it will only lament his own insignificance, and his heart will tremble uncontrollably.

"Sir, the thunder and lightning this time seems to be thicker than the last time, and the purple energy contained in it is also thicker, so it must be more powerful!"

Yu Ji shouted to Wu Liang again at the top of his voice.

"Uh-"

Wu Liang's ears were still ringing, but he could hear Yu Ji's words clearly.

More powerful...

And it still seemed like it had chosen a target, hitting the sinkhole accurately...

Wu Liang didn't know what this meant, but he was certain that the secret of this secret place must be related to the sinkhole, but they hadn't figured it out yet.

Perhaps, when this vision ends, the secret will be revealed!

In addition, Wu Liangliang felt a little lucky.

Fortunately, he hesitated, otherwise if he had rashly entered the sinkhole to investigate, he would have been torn into pieces by the lightning that followed.

next moment.

"Rumble—!"

A huge shock occurred again.

"Everyone get down!"

Wu Liang is already

No longer insisting on contending with such a strong earthquake, he immediately ordered everyone to lie down on the ground to maintain their shape, so as not to stagger around and be easily injured.
