At the same time, bursts of roar came from the valley shrouded by the array behind the stronghold.

There are several dark pits in the valley. Dozens of Qi practicing friars and more than 100 congenital friars are working hard in the pit.

The roar like thunder came from the black holes in the depths of those giant mines.

In a room in the stronghold, a man in a dark green robe was standing at the table with a very dignified look.

On the stone table in front of him, a three-dimensional map condensed by light blue spiritual power is slowly floating there.

Looking carefully, it is not difficult to find that this three-dimensional map depicts all the scenes of this hidden valley.

In the mountain formed by a pile of light blue spiritual power, there was a particularly conspicuous earthy yellow spiritual power mixed in, which occupied almost one-third of the underground of the valley.

"Unexpectedly, this is a large pentzite vein!"

The man looked at the earthy yellow power across the valley in the map, and a happy look flashed in his eyes.

However, at this time, a spiritual mirror beside him suddenly emitted a bright red light, which was particularly eye-catching.

Seeing this, the man frowned slightly and sent out a messenger.

Before long, a middle-aged man in the middle of foundation construction came to the man's room.

The middle-aged man's face was a little pale, and his breath was a little uncertain. He looked as if he had not recovered from serious injury.

"I've seen elder martial brother Mu!"

When he saw the man in dark green robe, he immediately bowed.

The man surnamed Mu glanced at him, then nodded slightly and said:

"How's your injury?"

"Tell elder martial brother that you have recovered more than half!"

The middle-aged man was stunned and answered truthfully.

The middle-aged man, named Wu Peilin, is an inner disciple of Wuji sect. He was seriously injured in the fight with Qingyun monk a month ago.

Finally, he had to retreat from the front line and come to this secret stronghold to recover.

After hearing Wu Peilin's answer, the man surnamed Mu immediately said:

"Someone just touched the warning talisman set by gukou. Go and see if someone found it."

"Yes!"

Wu Peilin immediately bowed his hands and took orders. Then he turned and walked out of the room.

……

On the other hand, Shen Feng didn't approach this secret stronghold rashly after he found it. Instead, he immediately turned and swept away in the direction of Linhai county.

Although he doesn't know who built this stronghold, he knows that he must inform Qingyun gate as soon as possible.

Moreover, since there is a stronghold here, other monks are bound to appear, so he'd better leave first.

In a dense jungle, a figure is moving rapidly.

Suddenly, Shen Feng felt a sudden tremor in his heart, and then an inexplicable chill swept over his whole body.

Before he could react, a sharp sword fell from the sky and hit the place where he stood.

At this critical moment, a jade card around Shen Feng's waist suddenly shone with an aura. In the twinkling of an eye, a seemingly transparent magic light curtain was formed in front of him.

"Boom ~"

With a loud noise, the sword Qi fell directly on the light curtain, and the terrible spiritual power fluctuated wildly. In a short moment, the vegetation, mountains and stones within several feet were razed to the ground.

After the dust settled, Shen Feng lay down on the ground unharmed, but the jade card around his waist and the light curtain protecting him disappeared.

However, at this time, on a towering ancient wood not far from him, a figure in black appeared out of thin air.

The figure in black is naturally Wu Peilin who was ordered to investigate.

Although Shen Feng had quickly left the hidden valley, Wu Peilin still found Shen Feng's trace with some means.

Originally, he thought the other party was just an ordinary Qi training friar. For the sake of the safety of the stronghold, he waved a sword to get rid of him at one fell swoop.

But what happened just now made him look dignified.

He just looked at it clearly. When his sword Qi fell, the jade pendant on the Qi practicing friar broke and formed a protective light curtain in front of him, which blocked his sword Qi.

As an inner disciple of Wuji sect, Wu Peilin's eyesight is naturally much stronger than that of ordinary monks.

At a glance, he saw that the jade pendant around Shen Feng's waist was actually a rare body protector.

This kind of body protector is usually given by high-level friars to their proud disciples or their descendants to protect their lives.

Although he is only an inner disciple, he also knows that some disciples with extraordinary talents in the sect will get the body protector and spirit weapon rewarded by immortal Jindan when they just start to learn.

So Wu Peilin couldn't help feeling tricky when he saw that the Qi monk had this kind of body protector.

I am deeply afraid that this Qi practising friar is a disciple or direct descendant of a high-level friar, which will cause disaster for himself.

In fact, there's nothing wrong with him, but Shen Ruiling specially entrusted Zhao Jie to refine this body protector.

When a person with a jade pendant is attacked by the level of the foundation period, the jade pendant will turn into a light curtain to protect the wearer, which is enough to stop the full attack of the friars in the middle of the foundation period.

This is why Shen Ruiling can rest assured that Shen Feng will come to the border battlefield.

When Wu Peilin hesitated, Shen Feng had climbed up from the ground.

When he felt the pressure from Wu Peilin that belonged to the friars during the foundation period, his face couldn't help getting gloomy.

He thought that even if he came to practice his Qi and became a full friar, he was sure to run for his life.

But there was a friar who built the foundation, so he really had no choice.

Is he really going to die here?

No, he was unwilling. He promised grandpa to see the beautiful scenery on the foundation!

Shen Feng's eyes flashed an extremely cold and unwilling look, staring at Wu Peilin not far away.

Aware of the strange color in Shen Feng's eyes, Wu Peilin frowned and immediately showed a killing intention in his eyes.

From the look in Shen Feng's eyes, he actually felt a potential threat, which made him immediately strengthen his killing idea in his heart.

His figure swept down from the tree, the black sword in his hand waved again, and a black sword several feet long waved to Shen Feng and killed him.

Carrying the sharp sword Qi, the sword awn swept up the surrounding vegetation fragments and attacked the tiny figure with the momentum of destroying heaven and earth.

Just when Wu Peilin thought that all the dust was about to settle, a dark iron stick emitting golden light rotated rapidly and inserted into the ground in front of Shen Feng.

The sharp sword light fell on the black iron staff and immediately spread to both sides.
