Seeing that Su Yu had nodded madly, Mu Shishan didn't say anything more. With a light smile, she said, "let's go."

Hearing what Mu Shishan said, Su Yu could only nod gently and then follow up.

This time, in addition to Mu Shishan and purple charm, there was only Su Yu who followed Heng Yanlin.

The four of them stepped on the desert and came to the front door of the Institute against the dazzling sand wind.

At this moment, the gate is closed, and there is a faint gloss on the surface. It doesn't look like an ancient building, but like a newly built one, which is particularly new.

Heng Yanlin turned his head to Su Yu and asked aloud, "do you know how to open this door?"

Su Yu heard Heng Yanlin's inquiry, and then a helpless smile appeared on his face. He opened his mouth to Heng Yanlin and replied, "Mr. Lin, this institute is my first time to come, and I don't know how to open it."

Hearing Su Yu's answer, Heng Yanlin angrily threw a big white eye at him and said, "since you don't even know how to open the door, what are you doing with it? It's useless!"

This made Su Yu feel inexplicable in his heart. Why was he scolded by hengyanlin?

Immediately, Su Yu saw Mu Shishan's eyes, and then thought of what Mu Shishan had just said, and secretly thought, "is it really like what Mu Shishan said, and now Hengyan Lin is getting nervous?"

No matter whether Heng Yanlin was getting nervous or not, Su Yu naturally couldn't contradict him. He could only nod his head repeatedly, bow down and say, "Mr. Lin, you're right. I'm really useless. Isn't it just relying on you?"

Hearing Su Yu's words, Heng Yanlin also felt a little speechless, and thought to himself, "I have never seen such a brazen person, and I can say so shamelessly, but I have no way to fight back."

Therefore, Heng Yanlin didn't know how to fight back. He could only glare at Su Yu fiercely. Immediately, he raised his head and looked at the metal gate in front of him. He took a few steps forward. Immediately, his heart moved slightly, and there was a vast spiritual force rushing out of his sea of knowledge, covering the metal gate.

After a while, Heng Yanlin felt the mystery of this metal gate. The countless lines were intertwined vertically and horizontally, and the inscriptions outlined were very mysterious, full of a mysterious flavor.

This attracted hengyanlin quite curious, and he couldn't help sinking his mind and began to study.

These lines are too complex and mysterious, so it is also difficult for Heng Yanlin to solve them. Fortunately, he was also an original emperor in his previous life, and he was very good at many arrays. Therefore, it was not long before Heng Yanlin solved the array of the metal gate in front of his eyes.

Immediately, Heng Yanlin slightly raised his head, and his bright eyes as bright as stars under the sword eyebrow flashed a look of victory. Then the corners of his mouth slightly tilted, showing a very confident smile, turned his head, looked at Mu Shishan and other three people, and said, "OK, I already know how to open the door, come with me."

Hearing what Hengyan Lin said, mu shisan and the three of them all showed a surprise on their faces, and Su Yu shouted with great exaggeration, "Mr. Lin is a cow!"

Then, Heng Yanlin stepped forward, came to the front of the metal gate, squinted his eyes, immediately raised his palm and gently patted on the surface of the metal gate.

"Hum!"

Suddenly, on the surface of the metal gate, there were beautiful light patterns fluctuating, which immediately turned into a star map.

This is a nine house grid star map, which is a little similar to the star map shown by the iceberg barrier from the first floor to the second floor.

Seeing the nine palace grid map, there are stars swimming on it. A faint smile appeared on Heng Yanlin's handsome face, even slightly raised his palm, and then quickly pressed it on a light spot, shaking rapidly.

With the stars turning rapidly on the palm of hengyanlin's hand, a pattern appeared on the surface of the metal gate, twisting, but emitting strange lines, as if it were a road of stars, which was particularly strange.

Seeing this beautiful starry road emanating from it, Mu Shishan and others standing behind Hengyan forest couldn't help but stare wide and exclaim.

This is the first time they have seen such a landscape, which makes them a little difficult to extricate themselves.

"Boom!"

When the starry road is connected into a line and completely presented, there is a vast brilliance spreading, which immediately sends out a fiery atmosphere, causing the whole metal gate to "boom" and make a sound. Immediately, countless lights overflow, and then the metal gate begins to vibrate and gradually open.

"Hoo -"

A strong wind full of fishy smell roared out of the metal gate, like ghosts crying and wolves howling, which made people feel numb and palpitating.

Although Mu Shishan said that she was very calm in many things, and she became more brave after embarking on the road of cultivation, this does not mean that she is not afraid of these ghosts if she is brave.

So when hearing the howling wind like ghosts crying and wolves howling, Mu Shishan's delicate body couldn't help shaking, and there was a trace of fear in her beautiful eyes, but she soon remained calm and didn't say much.

Heng Yanlin is very sensitive to the surrounding environment, so the subtle fluctuations in Mu Shishan's body can't hide him.

Therefore, Heng Yanlin just smiled faintly, turned his head to Mu Shishan, and asked softly, "what's the matter? Are you afraid?"

Hearing that Heng Yanlin said he was actually afraid, Mu Shishan immediately felt a little flustered in her heart, and immediately pursed her lips. At the same time, her delicate and beautiful face also became a little red, glared at Heng Yanlin, and said, "are you kidding? How can I be afraid? What's the fear?"

"Really?" Heng Yan Lin asked with a smile.

"Yes!" Mu Shishan's voice suddenly became a little high pitched.

"Well, since it's like this, why don't you go first?" Heng Yanlin asked with a smile.

Hearing Heng Yanlin's words, Mu Shishan's eyes suddenly changed slightly.
