Therefore, when Tang Wulin was moving slowly underground, he was not discovered by various detection instruments of the North Sea Corps. On the seismometer, only normal fluctuations under the ground were displayed. A person's activities were far from enough to make the seismometer emit an alarm.

In this way, Tang Wulin took a break when he was tired, and continued to dig after recovering. He didn't even know how long he had been digging.

During this period, he returned to the ground to rest twice. When he was so hungry, he returned to the sea and hunted a sea soul beast. He cut the sea soul beast into sashimi with his golden dragon claws as food. After recovering some physical strength, he returned to his underground world to continue digging.

"Ding--" A crisp sound suddenly appeared, and Tang Wulin's movements suddenly stopped. Hair all over his body stood up, and his whole body quickly calmed down.

What's going on?

Undaring to release the light from the blue silver grass, Tang Wulin could only release his own qi and blood soul ring. Under the illumination of the golden halo, he was surprised to see that at the end of the passage he was digging, a metal plate blocked the way.

Metal plate? Is this the inside of the North Navy? Is it an underground fortification or is it isolated from the outside world?

Tang Wulin gently pressed his palm against the metal plate and felt it silently.

He is already a forge who is close to the level of a saint craftsman, and his familiarity with metal is far beyond ordinary people. He can basically determine the characteristics of a metal through touch and mental perception.

That's what he did now, and soon he realized that what he had in front of him was a very close, not particularly rare, but very strong. It was a type of titanium alloy.

There is no energy fluctuation in it, that is, this is not a large soul guide, it is just a pure alloy.

This made Tang Wulin feel much more relieved. If it was a soul guide, he would be in trouble. At least he had to find a way to continue to go downward and bypass this metal wall. But if it was just a simple metal wall, it meant that he might have entered the outer layer of the underground fortifications of the North Sea Legion. As long as he broke through this metal wall, he could enter the interior of the North Sea Legion.

His heartbeat accelerated slightly. After thinking for a while, Tang Wulin slowly stretched out a finger, and the dark golden light blade slowly drilled out from his fingertips, and then quietly pierced into the rare metal in front of him.

Can the toughest rare metal be compared with his dark gold terror claw? After the sharp blade pierced, it slowly rotated under Tang Wulin's control, and a hole was drilled out soon.

A faint light quietly released in front of the Dark Gold Terror Claw, extending further away. After a while, Tang Wulin felt a lighter in his fingertips, and he knew that he had penetrated.

He quietly took his finger back, and he couldn't help but be shocked.

The thickness of this metal wall is two feet away. Such a thick alloy wall has absolutely super defensive power and extremely expensive construction. The North Sea Legion is really willing to invest a lot of money!

A faint beam of light came through the small hole. For some reason, when he saw this light, Tang Wulin felt like tears were flowing. Finally, he saw the light belonging to humans again! Since he climbed to Devil Island, he has been living an inhuman life. Finally, he can see some popularity.

Although it is just a small hole, with this small hole, Tang Wulin's spiritual power in the Lingao Realm can slowly enter the small hole and silently sense the internal situation.

Just as he judged, this place was indeed an underground fortification of the North Sea Legion, and to his surprise, it was a huge warehouse. There were a wide variety of soul-guided weapons and equipment in the warehouse, the most of which were fixed-mounted soul-guided shells. There was no doubt that Tang Wulin accidentally entered the most important storage warehouse of the North Sea Legion. No wonder the exterior wall alloy was so heavy.

The biggest advantage of a warehouse is that there is no one, and the biggest disadvantage is that the defense outside such an important warehouse must be super strong.

What should I do?

In any case, let’s talk about it first. If it really doesn’t work, you can still return the same way. You can move in or backward. Let’s see if there is a chance to go out in this warehouse.

Thinking of this, Tang Wulin thought for a moment and set the exit in a dark corner north of a shelf, close to the ground. This position is the least easy to discover.

With the cutting of the dark gold terror claws, a piece of square metal was slowly cut out. In order to be as low-key as possible, he just cut out a small outlet that was one foot square. With his figure, it was really hard to get out.

The fresh air made Tang Wulin's chest wide open, and he almost moaned comfortably. He quietly drilled out of the hole and re-enclosed the metal cover. As long as he didn't look at it carefully, it would be impossible to find it.

Suddenly, a sense of fear arose from the bottom of his heart, and Tang Wulin's whole body stiffened and he hurriedly leaned against the wall and did not dare to move.

But soon he knew where this sense of fear came from. The sense of fear came from the shelves with skeleton marks in front of him. On the shelves were placed in fixed-mounted soul guide shells.

Tang Wulin has learned a lot about fixed-mounted soul-guided artillery shells in the academy. After all, it is the most terrifying weapon of human beings in thousands of years. It is said that even the most powerful fixed-mounted soul-guided artillery shells, even the Extreme Douluo, dare not fight head-on. It can be seen that its power is.

In terms of size and logo, these fixed-mounted soul-guided shells in front of them are mainly between level 4 and level 6. This is already the most powerful fixed-mounted soul-guided shells that normal fighter jets can carry. More powerful shells require super mechas to carry to ensure safety.

Tang Wulin did not move, but quietly released his mental power to feel the situation in this warehouse.

Through mental feedback, he quickly determined that this was a warehouse of about 3,000 square meters, and more than 50% of the ones stored were fixed-mounted soul-guided shells. If so many shells exploded, the entire North Sea Legion base would probably be blown away.

In addition, there are some mecha reserves, all of which are standard yellow-level mechas.

To be precise, this warehouse stores quite powerful strategic materials, but it is not the top-level one. At least there are no fixed-mounted soul guide shells above level seven and higher-level mechas.

There are surveillance cameras in the warehouse, but they are only in the most critical position. This means that Tang Wulin is not so easy to be discovered, as long as he is careful.

There is still a chance!

The mental power cannot leave the warehouse, and the metal jade around it is too thick, so Tang Wulin doesn't know what is going on outside.

After carefully remembering the positions of all cameras, Tang Wulin began to move quietly. He had to leave his entrance first. In this case, even if he was discovered, at least the entrance would not be so easy to be discovered, and there would be a chance to escape later.

The only thing that is thankful is that this kind of warehouse that stores fixed-mounted soul-guided shells cannot have an attack system. Otherwise, once the attack system launches an attack and detonates the fixed-mounted soul-guided shells, it would be a devastating disaster.

I looked around the wall. The warehouse was very closed, with air, humidity and temperature controlled within a certain range. What should I do? I can't get out of here! There must be a strong defense force outside. Without an internal pass, even if I can break out of the gate, I will be discovered immediately. This is the North Sea Legion. Although Tang Wulin is a one-character battle armor master, he doesn't think he can break out so hard with his own strength.

Just as he was wondering if he should dig the tunnel again and find another exit.

Suddenly, with a series of electronic sounds, the heavy door of the warehouse slowly opened.

Someone is here?

Tang Wulin hurriedly hid in the corner.

Sure enough, after the door opened, several people walked in from outside—
Chapter completed!
