Fortunately, his body refining level is high enough and his body is strong enough, otherwise, even an ordinary spiritual warrior would not be able to reach this speed.

After entering the city, I first found an inn. After washing up, I had a casual meal in the lobby.

Called the guy over.

Even an ordinary fellow has innate strength in martial arts. This is the Shengyuan Realm, where almost everyone is a warrior, regardless of gender.

However, most of them are just body training and innate skills. After all, resources are still limited.

When the guy saw Bai Yunfei calling him, he looked around and saw that there was no one around, so he walked over.

"Sir, is there anything I can do for you?"

"Waiter! I am a warrior who came from a faraway land. I have heard of the great name of Echo Valley for a long time. I came here specially to take a look. I would like to ask for your guidance, Brother Xiaoer!"

As he spoke, he stuffed a medium-grade Yuanshi into the waiter's hand.

Upon seeing this, the clerk clenched his Yuanshi and looked in the direction of the shopkeeper. When he saw that no one was paying attention, he breathed a sigh of relief.

"Sir! It seems that you are not a local. This Echo Valley is not a good place. It is a well-known dangerous place in the Golden Dragon Empire. The stronger you are, the higher the danger will be."

"Oh! Why is that?"

"Echo Valley is a very special place. Once you enter it, you will always hear various echoes. If you are weak, the echoes will be smaller. If you are strong, the echoes will increase their power madly. Even a master of the Sky Control Realm will be injured if he does not have any special means. Moreover, this Echo Valley is said to be a huge formation, but no one can confirm it. In addition, there is a unique beast in this Echo Valley, named the Sound Beast. This beast has a unique way of attacking, which is sound. If an ordinary Xuanwu Lingwu is not able to respond in time, he may be shocked to death. So this Echo Valley is simply a Jedi!"

After hearing the waiter's introduction, Bai Yunfei was surprised. It turned out that Echo Valley was so dangerous! "So what is the reason for this Echo Valley to attract warriors to come here?"

Hearing this, the guy laughed, as if to say, "You asked the right person."

"To be honest, there are treasures in this Echo Valley. Among them is a kind of ice silkworm leaf. This leaf is said to have magical effects. Not only can it bring the dead back to life, but it is also extremely magical. It can also detoxify injuries, and even temper internal strength and improve cultivation. It is simply an omnipotent treasure. It is said that the value of an ice silkworm leaf is equivalent to one million Yuan stones."

After hearing the waiter's introduction, Bai Yunfei immediately said, "Since there are ice silkworm leaves, do we have ice silkworms?"

Hearing Bai Yunfei's question, the clerk was stunned for a moment and said, "Of course there are ice silkworms. This is the real good stuff. It is said that the ice silkworms are sacred in this Echo Valley. They come and go without a trace. Although their strength is not strong, the ice silkworm silk is a treasure. If it is refined into clothing, it will be impervious to water and fire, and invulnerable to swords and guns. The protective effect is several times better than metal armor."

After hearing this, Bai Yunfei showed a look of surprise. If he could get an ice silkworm, he would be really rich. This is not just spinning silk, it is definitely spitting out Yuan Stone!

Seeing Bai Yunfei's expression, the waiter smiled and said, "Sir! This ice silkworm is not simple. Even if one wants to obtain one at the Sky Control Realm, it is as difficult as ascending to heaven. It is said that this ice silkworm can evolve, but I don't know what conditions are required."

After listening to the waiter's introduction, Bai Yunfei felt like he was in a state of excitement and wanted to leave immediately.

Seeing Bai Yunfei's anxious look, the waiter kindly reminded him, "Sir! You have to think carefully. The dangers in Echo Valley are deadly. There are not only ferocious beasts, but also human forces inside. Although it is a rumor, you have to believe it. After all, out of ten people who go in, only three or four can come back."

Bai Yunfei bowed and said, "Thank you, little brother! I will be careful!"

After saying that, he ate something, walked out of the inn and headed towards the city gate.

The waiter looked at Bai Yunfei who was leaving with a look of regret, and murmured, "Alas! Another fool. How many of those who enter can come out alive!"

He shook his head, took the Yuan Stone and walked aside.

They soon arrived outside the city gate, and after a little asking, they found out where Echo Valley was.

This is a very famous dangerous place in the empire, more famous than the Ghost Fog Forest.

It was only afternoon at this moment, and Bai Yunfei simply followed the crowd and soon arrived outside a strange valley.

There is a circle of huge rocks standing all around, dozens of feet high, and spreading out for more than ten miles.

There is a passage in the middle, which should be the so-called Echo Valley.

The Echo Valley covers an area of ​​only a dozen miles in radius, which is not too large, but it is a circular structure, and this road is the only passage leading to the interior.

Some warriors planned to go directly over the rocks and reach the interior of Echo Valley, but even those who were at the Sky Control Realm could not do that.

As long as they appear above, the terrifying sound waves, like thunder from the sky, will knock down anyone who dares to break the rules.

Without exception, almost all of them were wiped out.

So after that, no one dared to take shortcuts anymore.

There is no wrong version in the 1619 book forum!

There were quite a few warriors entering Echo Valley. Bai Yunfei and dozens of them had already reached the entrance of the valley.

After arriving here, the warriors in front began to move cautiously.

Bai Yunfei stood behind and watched, and found it quite interesting.

There were more than thirty warriors traveling together, and Bai Yunfei stood at the end.

As if they were thieves, the leader had already tiptoed into the Echo Valley, and the others behind him did the same.

Soon it was Bai Yunfei's turn.

Bai Yunfei was not so exaggerated, but his footsteps became extremely light, trying not to make any noise.

This is a circular passage, but there are countless holes on the stone wall near the inside.

It's more like a sieve.

Bai Yunfei was a little confused, so he simply followed everyone.

Every few dozen feet, there would be a cave entrance. It was not big, only about one foot in size, but it was so deep that no one knew its depth.

It felt like we had been walking for several miles, and for some reason, a warrior suddenly screamed.

It was as if some horror mode was activated. Along with the screams, sounds like ghost crying came out from the holes around, and then gradually grew louder.

From those one-foot-sized holes, there seemed to be the roar of an ancient wild bull, like thunder.

Bai Yunfei was close to a cave entrance, but he shivered, his body trembled, his heart beat faster, and a stream of hot blood almost spurted out of his mouth.
