While Sang Nan was discerning the patterns on the pillars in the palace, Gong Yehan had been studying the two doors that had been knocked down. Pen, fun, and www.biquge.info

He noticed that from the time Sang Nan and Ji Poyu used brute force to hit the door, until the door fell off, the two door panels had never been deviated, and he also specially asked Norsang and others to help turn the door over, and found that behind the two gates, there was no latch at all, and he instantly had an inference in his heart.

This hall door should be some kind of door lock, as the name suggests, refers to its shape although it looks like a door, but in fact it is a lock, they used to build the royal palace, they also used this means, encountered this kind of door, only with the matching key can be opened.

However, Gong Yehan didn't expect that Sang Nan and Ji Poyu's "unlocking" method would be so rough, and they actually knocked the entire door lock off with brute force.

At this time, Sang Nan had already left the pillar and walked towards the end of the palace, if there was still a gate, he would naturally take advantage of the fact that he and Ji Poyu were in a state of beasthood, and continue to violently crash open.

Gong Yehan, who was looking for a "keyhole" on the wall at the end of the palace, saw Sang Nan coming over, and hurriedly stepped forward to express his judgment.

"Childe, that door just now is a door lock, and you need a key to open it! Casually, I suspect this wall has a similar mechanism. ”

"But what did you find?" Sang Nan looked at the high wall at the end of the palace and asked lightly.

"I've checked and found this one to be suspicious!" Gong Yehan pointed to a section of the wall and said.

Hearing this, Sang Nan slowly came to the wall, knocked on the wall with the handle of the seven-star cone, and found that there was a clanging sound, and it turned out that the entire section of the wall was actually made of metal.

"I measured it, and this section of the wall is about 15 meters long." Gong Yehan noticed the look of surprise in Sang Nan's eyes and added.

Sang Nan nodded, and by the light of the fire, he repeatedly observed every inch of the wall, but he couldn't find any traces of depression and bulge, and finally set his eyes on the two monster reliefs in the middle of the wall.

Obviously, the two reliefs were exactly the same as those on the palace gate, also metal, and even taller, and at this time they were looking at the people in front of them with their mouths open.

Suddenly, Sang Nan held the seven-star cone, and kept stabbing at the body of the relief, he moved quickly, his face was expressionless, and in the eyes of everyone, he looked a little weird and crazy.

In fact, Sang Nan was very calm, and when he learned that this section of the wall was 15 meters long, he completely gave up the idea of pushing it down by brute force. And according to Gongye Han, then there must be a "keyhole" for inserting keys on this wall.

Therefore, in the midst of everyone's puzzled gaze, he used this seemingly stupid method to find the "keyhole", and the tip of the cone pierced the metal wall, making a tinkling sound.

Flutter! He suddenly felt a slight pressure on his left hand, and the seven-star cone seemed to pierce into a hole. Sannan let go of his hand abruptly, leaving the cone in the hollow.

"In its mouth!" Ji Poyu's eyes were sharp, and he saw the seven-star cone inserted in the monster's mouth at a glance, and couldn't help shouting.

Sang Nan was ecstatic in his heart, and asked Gongye Han to hold a torch to illuminate the head of the monster relief, and found that the huge mouth of the blood basin on the left side had been poked into a big hole, it seemed that the mouth of the relief was empty, but there was a layer of camouflage on the surface, and everyone did not see it.

He drew a scoop according to the gourd, raised the seven-star cone in his right hand and stabbed it at the mouth of the relief on the right, and sure enough, he touched it. But when he removed the surface camouflage, he was suddenly stunned.

It turns out that the hole in the mouth of the relief is an equilateral triangle.

It can't be such a coincidence, right? Sang Nan looked at the seven-star cone in his hand, which was also a triangular vertebrae, and his heart suddenly became nervous and excited.

Could it be that his own seven-star cone is the "key" to this lock?

He gently held the seven-star cone, and inserted it hard along the triangular "keyhole" until it was out of control, his face showed a touch of joy, and then inserted another seven-star cone into the "keyhole".

"Two cones need to be rotated outward at the same time!" Gong Yehan suddenly said with a determined expression.

Sang Nan glanced at Ji Poyu and asked him to come over to help, but saw Ji Tieyi suddenly step forward and hold the seven-star cone on the left side, "I'll come!" ”

"Assault camp, watch out!" Sang Nan admonished, glanced at Ji Tieyi again, and then said, "Three, two, one, turn!" ”

At the same time, the two of them vigorously rotated the taper handle outward to the end, and then took a few steps back, concentrating on vigilance, as if facing a great enemy.

Thundered! Suddenly, everyone felt a vibration beneath their feet, and the rubble fell from the wall, turning into dust in front of them.

Whoa! Bang Dang! The mechanism was transmitted, the deadbolt flicked and contracted, and an incomparably beautiful voice sounded:

Crunch ......

The seamless high wall actually began to move to both sides, slowly opening a gap, and a ray of light projected in, slowly illuminating the interior of the palace, Sang Nan and Ji Tieyi looked at each other and smiled.

Finally it worked!

The gap grew bigger and bigger, and finally it was completely opened, and it was a huge door that was a full 10 meters wide, but when everyone saw everything in front of them, they all became sluggish, their eyes were amazed, and they were so shocked that they couldn't speak.

In front of him was a world with a strange environment: the sky was a magnificent lilac, with silky light blue clouds floating on it, and a dark purple sun hung overhead, glowing with a not too dazzling light, like a demonic eye.

It's a city on a grand scale, with a straight north-south avenue running through the city with no end in sight.

Around the city, there are lush vegetation peaks and babbling streams, and the scenery is pleasant, but there is not half a figure in sight.

Their current position was on a hillside, with wide stairs at their feet, each seven or eight meters wide, and down the stairs was the end of the avenue, which was the edge of the city.

Sang Nan asked people to go outside to transfer the soldiers in, and then led the group along the avenue, mightily forward.

The width of the avenue is almost 100 meters, and the ground seems to be some kind of cream-yellow granite, soft in color, polished very smoothly, comfortable and gentle to walk on.

On both sides of the avenue are buildings of different shapes, generally taller than those on the Moya Continent, and most of these buildings are built of blue, yellow, and brown materials, making the whole city look solemn and full of mystery.

Gong Yehan walked in front of a building, touched and smelled, and then let out a wail in a trembling voice:

"This is a special five-colored soil! They used it to build houses? ”

After hearing this, everyone's expressions froze, and they instantly remembered that they had walked for so long, and they hadn't seen half a figure, the huge city was empty, and the surroundings were unusually quiet, which made people feel creepy.

"Oh my God! What kind of place is this? ”

"yes, what's a little ghostly!"

…………

The atmosphere was a little weird, and everyone began to talk constantly to hide the tension in their hearts.

Sang Nan remembered the conversation between his grandfather Sang Haiyuan and himself, and said lightly:

"This road is called Huangquan Avenue!" (To be continued.) )
