Nameless Ridge.

After watching Tian Tian fall asleep, Ling Chen came here again, and then went straight ahead, and soon came to the place where he first encountered the mountain giant.

On the left, there is the mountain that is extremely steep, almost vertically rising into the clouds, and on the right, it is a low mountain formed by mountain giants, or mountain giants. The difference is that the current mountain giant will no longer stop him, and even the breath does not emit the slightest, but seems to have entered a quiet sleep.

Ling Chen glanced around, in the central area of the Nameless Ridge, there were only these two mountains, and the rest of the places were flat, and even the weeds were relatively sparse, so there was no trace or trace of the "tribe" at all. Ling Chen summoned Xiao Ash and said, "Xiao Ash, continue the previous search." Is there any hidden entrance around here? ”

As soon as Ash appeared, the sharp corners above her head flashed with gray light. Without the aura of danger, this time Xiao Ash ran forward very easily, and Ling Chen followed behind inch by inch. For Xiao Ash, he already has 10,000 points of trust.

Little Ash ran in front of the vertical mountain and stopped, wagging his tail, and looking up at the steep and somewhat excessive mountain wall in front of him, the gray light on the horns was brighter and richer. Ling Chen stopped beside him and said in a low voice, "Could it be that there is a hidden entrance on this mountain wall?" ”

"Woo woo......" Ash responded with a cry, walking left and right in front of the mountain wall, sniffing with his nose. Ling Chen also came within half a step, reaching out and tapping on the mountain wall, looking for any hollow areas.

Xiao Ash sniffed left and right in front of the mountain wall for a while, stopped in the center of the south direction of the mountain, raised his head and looked at the mountain wall above him for a short while, then took a few steps back, and then suddenly ran and accelerated, jumped high again, and slammed the horns of his head into the smooth stone wall at a height of one meter.

With a "bang", the little gray horn knot hit the mountain wall firmly, and the gray light on the horn flashed...... Then, Ash was bounced back hard, fell on all fours, and finally got up, stretched out his right paw and scratched his horn that was hurting, and made a "whine" sound from his mouth.

"It's okay, Ash...... The place has hidden passages? Ling Chen looked at the place where Xiao Ash had just been hit, and he was about to reach out to touch it. Suddenly, a "click" sound sounded, it seemed to be the sound of gear turning, in the continuous sound, the smooth in front of the eyes could not find any unusual mountain wall, suddenly there was a dislocation, a full five meters high, five meters wide mountain wall slowly protruded, has been protruding about half a meter thick, and then began to move evenly sideways.

As the side of the mountain wall moved, a wide passage entrance gradually appeared in front of Ling Chen's eyes.

The traverse of the mountain wall continues, and the sound of the gears turning is smooth and even. Half a minute later, the lateral movement of the mountain wall stopped, and an entrance five meters wide and five meters high appeared intact.

This is...... Organ?

Ling Chen's heart was filled with shock. The sound just now should indeed be the friction of metal gears, that is, some mechanical mechanism is manipulating this stone door. The weight of the mountain wall, which is five meters high, five meters wide, and half a meter thick, must be an astonishing number, what mechanism can drive such a heavy stone gate. Moreover, the stone gate was closed in perfect harmony with the mountain wall, and he could not find any trace of it until it was opened. Of course, such a mechanical mechanism cannot be formed naturally, it can only be created by man, but its degree of fineness is really terrifying.

The hidden passage was right in front of Ling Chen's eyes, Ling Chen didn't enter it right away, there might be unknown dangers hidden inside, and he needed to be well prepared.

With hundreds of rock ghosts, plus mountain giants, and the reward of killing the first Heavenly Absolute Boss, Ling Chen has now accumulated 58,350 skill potential points. These skill points are enough to increase his ability by a large margin in no time. Before entering this mysterious stone gate that led to no apparent direction, he chose to immediately distribute these skill points, so that he could have more combat power and self-protection ability in the face of possible dangers.

Although 50,000 skill points are a lot, the skills that Ling Chen has are more special than the other, and the skill points required for upgrading are also astronomical. The Fortune Player needs 300,000 skill points to upgrade, and the Soul Death requires 100,000 skill points to upgrade to one level, and these 50,000 skill points are not enough to even upgrade them to one level. After thinking about it for a while, Ling Chen decisively pointed the two most commonly used attack skills, Ling Tian Slash and Ling Tian Break, directly to the full level.

：lv7―1600→lv8―2200→lv9―3000→lv10。

14,600 skill points were consumed, and in the continuous prompt sounds, the skill levels of Ling Tian Slash and Ling Tian Duan all reached the full level of lv10, and the damage judgment, attack range, and additional effects all reached the maximum value. Subsequently, the Quartet Star Array was also raised to the full level by Ling Chen.

The attack range of the full-level four-sided star array is magnified to 15 meters around itself, and the damage judgment has also reached an astonishing 800%, which is worthy of being one of the strongest destruction skills from the God of War. It took 14,400 skill points to fill the Quartet Star Array, and the remaining 29,350 skill points, Ling Chen's relatively even points were on several powerful passive skills.

All of the four major battle tricks have reached level 6, except for the Imperial Weapon Technique, which stayed at level 5. Skill points have also been depleted to the last 1350 points remaining. In this way, all of Ling Chen's attack skills have reached the full level, and the power of the battle skills has also entered the advanced stage, all of which are due to the rewards of a Heavenly Absolute Boss. With everything ready, Ling Chen stepped into the passage behind the stone gate.

Trample! Trample! Trample......

Walking into the passage, the sound of footsteps is clearly clear. It was quiet ahead, and it seemed that there was no living thing but itself. Ling Chen looked back at the stone wall inside. Stout metal bars crisscross neatly on the stone wall, and hundreds of metal gears are placed on them, which are extremely complex, dazzling to see, and even more surprised in my heart...... It's these metal bars and gears that drive that huge stone door? The stone gate weighed at least a few thousand catties, what kind of person could complete such a huge project......

After walking forward with a light pace for dozens of steps, Ling Chen saw two lamps hanging on both sides of the stone wall. The lamp is round, fist-sized, and emits a soft, warm light, which does not look dazzling at all, but illuminates the surroundings. Ling Chen stared at the two lights for a long time...... Because they give Ling Chen, it is like an electric light in the real world!

At least, he didn't remember seeing such a lamp in Qinglong City, or any other town. At the same time, under the illumination of the light, Ling Chen suddenly found that the stone walls that made up this passage were unusually smooth, as if every inch and every corner had been finely polished. This passage embedded in the mountain wall was clearly artificially excavated. Generally speaking, such a passage should be extremely rough, with potholes on both sides, but this passage is a completely different scene. It is a huge project to carve out such a wide passage, and the stone walls are so delicate that they are almost perfect, and it is extremely difficult to do with the time and energy.

Who did it? Where would that "mysterious tribe" hidden here be sacred?

The passage was very long, and after Ling Chen walked a hundred and ten steps, the two sides suddenly became wide, and he had already walked into a stone chamber. The stone chamber is round, with a diameter of about 30 meters, and in the stone chamber, there are all kinds of rotating machinery densely distributed...... That's right! It's all mechanical! And it's all running, making a smooth, even mixing sound.

"It seems that yes, the only race that has disappeared can make something so complex that people can't understand it at all."

When Ling Chen was stunned, the bleak moon spoke faintly, and her voice was full of regret: "This race was forced to hide back then, and it has never appeared again, and now it has been almost forgotten, and I even thought that they had long been completely extinct. I didn't expect to be found by the little master...... In the past 10,000 years, if this race had not hidden, with their talent, wisdom, and creativity, the technology of the Shenyue Continent would have been at least a thousand years ahead of the present. ”
