.

Sure enough, he lived up to Xiao Han's expectations, and the most primitive method was useless. He knocked all the bricks and stones on the ground, and even didn't let go of the corners of the wall, but the sound that came to his ears was almost the same.

If this is really the second-level entrance, then this entrance must be controlled by the agency's messages.

Although the information of the agency is hidden, it is usually traceable and is usually made into practical things, such as magic wall lamps on the wall, which play a role in concealing the people’s ears.

However, although magic wall lights were also installed on the walls around the hall, Xiao Han carefully checked all magic lights, whether they were twisting or pulling, they did not move at all, and they did not look like the control gate of any mechanism.

The two of them worked in the hall for more than twenty minutes without any gains

At this time, Serena became a little impatient. Logically speaking, she shouldn't have done this, but as time goes by, the news that Kahn was detained by her will not be suppressed, and there is not much time left for them.

She didn't know how long she could suppress the news that Kahn was detained by him. Even if she was charged with trespassing the Queen's Palace, she couldn't do anything to Kahn.

"How many hours are there before dawn?" Xiao Han asked calmly.

"It's about four or five hours left." Serena closed her eyes and said, feeling it.

"Don't worry, if you really can't find it, it's not too late for us to retreat." Xiao Han said, the entrance is so difficult to find, and the coalition of the three tribes should not be easy to find in such a short time, because they have to deal with the return of the elves army at any time, so the treasures of the elves in the second level should not have been taken away by the coalition of the three tribes.

However, more than 70,000 years have passed since the war, and no one knows whether there have been any changes during this period. After more than a dozen elf queens, none of them discovered this secret?

This batch of treasures can guarantee the rise of the elves again. Maybe they did not dare to take them out. With the strength of the elves at that time, if this batch of larger treasures were taken out, it would be difficult to save them.

Anyway, there are multiple possibilities. Whether the second treasure is still there or not, everything depends on luck.

Xiao Han no longer looked for every clue, but carefully observed the entire hall. Although the hall was empty, if it was the entrance to the second floor, some instructions would definitely be left. In case no one knew where the secret was, information to crack the secret could be obtained through these instructions.

Since the ancestors of the Elf Clan built the second and third underground secrets, they would never want the things inside to be buried under the loess forever.

This observation really made him discover something wrong. Something was wrong. In addition to the dust on the ground, the magic wall lights on the surrounding walls.

He found that these magic wall lamps did not extend into the inside along a parallel line, but from the entrance to the hall to the opposite side of the entrance, there was a straight line tilted towards the inside.

Looking at the ground, if the ground is tilted downward, it can be explained that it is parallel to the ground, but the ground is indeed flat, which means that the magic lamp is deliberately artificially lowered the distance at a distance.

Maybe it was deliberately designed to create a unique aesthetic, but intuition told Xiao Han that there must be articles here, and it would be difficult to discover this if it was not back to the entrance of the hall.

Moreover, he checked that all the magic wall lamp holders were physical and had no trace of movement.

Will the agency be outside the hall?

A thought suddenly came to Xiao Han's mind, and he immediately turned around and ran out of the hall.

"What are you doing?" Serena suddenly saw Xiao Han running out and asked in surprise.

"Don't look for it inside, come out," Xiao Han replied.

Serena ran out too.

"Her Majesty the Queen, don't let go of an inch of ten meters away from this hall," said Xiao Han.

Generally speaking, if there is no control of the main gate mechanism, the control buttons of the mechanism message of this entrance should be within a range of ten meters, because the confidential entrances are time-limited and will be automatically closed as soon as the time reaches. If the distance is too long, the arrival time will inevitably be longer, which is not conducive to the rapid closing of the entrance channel.

"Okay" Serena immediately realized why, so the two continued their division of labor, searching for the wall of the passage one left and one right along the wall of the passage.

The information gate of the agency is most likely to be pressed on the wall because it is in line with the living habits of intelligent human beings, walking with lower limbs and upper limbs doing things, so the wall is the focus of inspection, and every small brick cannot be relaxed.

There is no obvious place to spit out, and the color of the wall is the same. Moreover, it has been so many years since the traces, and it is difficult to tell from the traces where it is often touched, so every piece must be taken care of.

Dongdong...

There were muffled sounds of knocking on the walls in the quiet corridor, which sounded quite faint.

While knocking, listening to the sound from the brick and stone walls, Xiao Han judged whether there was a possibility of space inside the walls.

The magic wall lights on the wall are more focused on, turning, pulling, pressing, and giving up before trying all three movements.

"Xiao Han" Just as Xiao Han was exploring silently, Serena's surprise voice suddenly came from behind.

Xiao Han immediately turned around and ran over

Serena pointed at a brick and stone on the wall with a happy face and said excitedly: "I just pressed hard and found that the stone had moved. Could this be the mechanism we were looking for?"

Xiao Han's face condensed, and he carefully observed the brick and stone on the wall. He reached out and tapped it lightly three times, then pasted it and listened carefully to the sound coming from inside. A hint of joy appeared on his face.

drink

Xiao Han reached out and pressed the stone, suddenly sniffed, pushing his arm inside, and the bricks and stones fell into the depth of half of the arm.

"quack……"

A harsh and heart-wrenching sound suddenly rang.

"Let's go" This time Xiao Han grabbed Serena's hand and rushed towards the hall

A scene they unexpectedly appeared, and the wall opposite the hall slowly sank, revealing a pitch-black hole, and a creepy sound came from inside.

What?

This is not like the sound made by humans or elves

Whoosh

A sharp arrow shot out from the black hole, which was as fast as a meteor

Why are there anyone inside? Xiao Han and Serena were both shocked. The cultivation level of the arrow that had at least reached the god level.

It is not difficult for the two of them to avoid this arrow, but the power of this arrow made them look at each other. Although this arrow did not shoot them, the force contained on the arrow was very terrifying. The arrow suddenly suddenly appeared in the wall several meters behind them, leaving only a small hole in the thumb path on the wall.

How hard the brick and stone materials used on the wall are, and this arrow can control the power so subtle, it can be called a magical archery technique.

But before they could come back to their senses, the second arrow, the third arrow... shot out from the dark hole.

Arrows

Good, this arrow is one arrow in succession, and one arrow is faster than the other. The energy contained in the arrow is even more terrifying than the first arrow just now

"Do not" Xiao Han pushed away Serena, who was a little stunned, and roared, dozens of wind blades were emitted, hitting a dozen long arrows coming towards him.

"Dingding..."

A series of impact sounds were heard, and more than a dozen long arrows were hit by the wind blade and fell to the ground in front of them, making a crisp sound.

The cold iron arrow Xiao Han took a breath slightly. The cold iron is a very good metal for casting weapons and has good devilishness. Some people actually use it to cast arrow branches, and the whole pole is filled with cold iron, which is too luxurious.

"This is the Kunwu arrow. I have seen it in the Elf Classic Book. This is the arrow branch specially used by the palace eunuchs 70,000 years ago." Serena picked up a cold iron arrow on the ground, looked at the special pattern on the arrow shaft, and exclaimed in surprise.

"Is this the mechanism inside shot?" Xiao Han glanced at the black hole in suspicion, but his intuition told him that these arrow branches were definitely not shot by the mechanism, and the arrows shot by the mechanism were definitely not so flexible, and must have been shot by humans.

And he is also an archery master.

Xiao Han also picked up an arrow, put it in front of him and took a closer look, then put it on his nose and sniffed it, and the light suddenly flashed in his eyes.

"What's wrong?" Serena asked.

"I smelled a trace of the undead," Xiao Han said with a heavy expression.

"The undead is impossible. How can there be undead due to the elves?" Serena denied firmly.

"My sense of smell is not wrong. The undead is also a kind of intelligent creature. When their cultivation reaches the god level, they can automatically restrain the undead energy in their bodies. Just now, I carefully checked the cold iron arrows that were shot out and found that there was a trace of undead energy entangled on it. Only the arrows shot by the undead have this special aura. If I expected it, the second underground palace might have been occupied by the undead," Xiao Han said.

"What should I do? How many undeads are there?" Serena was a little confused. "The souls of the elves will disappear after death, unless someone killed them and refined them into undeads."

"I don't know, if these undeads were refined, then the person who refined the undead was at least a master like Lich and the like." Xiao Han said, "Would you like to go down? Her Majesty Queen, you decide?"

Serena thought for a moment: "Next, will you accompany me?"

"Of course, I really want to see the underground treasures of the Elf Clan." Xiao Han did not hide his interest in the Elf Clan's treasures at all.

Although the first treasure of the Elf Clan was emptied, his huge number made him feel moved. The further down, the more precious the treasure, the less chance it would be.

"He really wanted to go down for the sake of treasure." A faint disappointment flashed in Serena's eyes.

"Go away quickly, the stone gate is about to close automatically." Xiao Han pulled Serena and rushed into the black hole. The huge stone gate behind him quickly closed, and the surroundings were suddenly pitch black.

Xiao Han took out the magic lamp, turned on the button, and a ray of light appeared in front of the two of them.

Not far from them, more than a dozen skeleton elves were looking at them with bows and arrows in hand.

It was indeed the undead of the elves, but they did not seem to be controlled by others, and they also had a trace of spiritual intelligence.

And they looked like they had a leader, an elf skeleton with a red ribbon tied around his neck, and these two golden flames were jumping from his collapsed eye sockets. This was his soul fire.

A skeleton elf who cultivates soul fire, the leader's cultivation level is at least not inferior to him.

"He is talking to me..." Serena's trembling teeth suddenly said to Xiao Han, looking panicked.

"What did he say to you?" Xiao Han asked.

"He asked me who I am, how could I smell the elves royal family? Also, he also said that this is the underground treasure house of the Elf Palace, and outsiders are not allowed to come in." Serena quickly explained to Xiao Han while looking at the skeleton elves of the fourth generation of red.

"Tell him your identity and see how they react?" Xiao Han said hurriedly. If the skeleton elves are not controlled by others, it is in the second floor. The elf eunuchs who were originally guarding the second floor of the underground palace have undergone some special changes. They are self-awakened undead, and some may also have memories of their lives.

Serena communicated with the skeleton elf leader as Xiao Han's instructions, and the two sides communicated back and forth for about a minute.

Serena's nervous expression stretched out, and she turned to Xiao Han and explained: "He said that his name is Si Liyue, and she is the captain of the guard on the second floor of the underground palace treasure place. There were originally more than 200 people here, but now only half of them have successfully transformed into skeleton elves. Now they are all his subordinates. However, only she and some of the more profound cultivation have recovered some memories, and the others have lost most of their memories. They can only instinctively obey her commands and several small team leaders because of the entrance to the second floor.

They were closed down and could not get out, and they all died in it. The bodies rotted into skeletons. I don’t know how many years they had been sleeping. She was the first to wake up, and then a few more awakens. Later, half of the skeletons woke up, and no skeletons woke up again. So they picked up the bows and arrows again, shouldered the responsibilities in front of them, guarding the treasures in the second underground palace, and looking forward to one day they could return them to the descendants of the elf tribe intact."

"Just just now, they suddenly found that the entrance to the second underground palace was opened. When they found you, they thought it was an enemy, so they attacked you," Serena continued to explain.

"What do they mean? Do you want us to go in?" Xiao Han asked with a frown.
To be continued...
