Lin Xinyi could hear the hurried footsteps of Bai Xiaofei and the others in the distance ahead, and knew that they were not out of danger yet, she roared loudly and took a big breath - her giant ass suddenly increased, like an air cushion stuffed between the sandwich wall, and the sandwich wall stopped again.

However, inside the sandwich wall, there was another sound of the gear turning, obviously next time, the pressure will increase again, this time, whether it is Lin Xinyi or the ghost stick, it can't be stopped, the ghost stick smiled in the dark: "What a big ass." ”

Lin Xinyi evolved ****** devouring a butt corpse brother in the early days of becoming a corpse brother, and at that time, she was still bent on killing Bai Xiaofei.

Lin Xinyi sighed lightly: "It would be nice if this ass was a little bigger." The ghost stick laughed loudly, and for some reason, Lin Xinyi suddenly remembered her dead parents, boom, and the wall started again--

Bai Xiaofei pounced forward, and the last one fell into the fork in the road, and behind him, the metal wall closed with a dragon roar. Bai Xiaofei didn't hear Lin Xinyi and the ghost stick's screams, but he knew that the two of them had no physiology.

Bai Xiaofei didn't dare to imagine the tragic appearance of Lin Xinyi and the ghost stick turning into two lumps of meatloaf in the wall, he just asked Ling Lan, "Can you find the way to the center of the tomb?" "--Lin Xinyi, ghost stick, you guys go, I will help you complete the unfinished battle!

Ling Lan pointed to a direction under his feet: "Dig here, I sense that there is a big cave below." ”

Little Fat waved his two knives together, cut down a few stones, and he said in surprise: "You can dig, not metal." Erdo said, "Let me come." With a low roar, he transformed into a mammoth corpse brother, digging into the ground like an excavator with a pair of fangs on his head, and headed underground, leaving behind him a passage that could be passed side by side.

After digging for a long time, Erdo suddenly felt the rock layer in front of his fangs suddenly disappear, and a bright light came through, and then he fell straight down, and the passage was dug through.

Bai Xiaofei and the others fell into the cave one by one, only to find that the cave is actually an incomparably vast hall, the walls of the hall are embedded with luminite balls, and the light is emitted by them, and the four walls of the hall are huge pieces of white jade, carved with pictures on them, there are large armies fighting, farmers and people harvesting, and there are kings and ministers playing against each other--

Nima glanced at it quickly: "This is a great achievement made by the monarchs and ministers of the Qin State in the past dynasties. ”

Bai Xiaofei didn't have time to read these stone "history textbooks" now, so he asked Ling Lan, "Where should I go next?" ”

Ling Lan shook his head: "No, my soul sensing has been disturbed - these luminous orbs are actually radioactive substances, and their radiation has interfered with my induction. "That's right, the so-called night pearls of the ancients are actually natural radiant substances, many of which are made of fluorite, and the light emitted is radiant light.

Nima pointed with his hand: "Wait, I know where to go - the images on the wall are based on history, as long as you trace the history of the Qin monarchs, you can find the first king of the Qin State - that is, Qin Feizi, he was sealed by King Xiao of the Eastern Zhou Dynasty in Qin Yi to build the Qin State, and the jade slab where Qin Feizi is located should be the exit." ”

Everyone looked at the stone carvings in the huge hall, only to find that the original stone carvings were not in the normal historical order, but chaotic, Sun Xiaohou was so anxious that he took a picture of one of the stone drawings, and suddenly the stone drawings retracted with a roar, and there was a sound behind the stone drawings, and a burst of sharp arrows shot out!

Bai Xiaofei and the others dodged one after another, and the sharp arrows shot into the air, and the little fat said angrily: "Damn, I should have thought that there must be a mechanism here!" Don't touch the stone map, everyone! ”

However, Nima's eyes lit up - because she found that the stone diagram that Sun Xiaohou had touched appeared in other positions, and actually changed the direction, she raised her hand: "I understand, this is an alternative tangram!" Or puzzles! We need to rearrange the entire history of the Qin State in order for this hall to pass! ”

Ling Lan glanced at the dense stone maps in the hall: "There are 37 kings in the Qin Kingdom, and there are many major historical events during them, and we don't know the order in which the stone maps are rearranged, which means that there are countless permutations and combinations, as long as you make a mistake once, the engine will be closed, which is also too difficult." ”

Nima said: "No matter how difficult it is, I have a hunch that the mechanism of this hall is not as simple as a burst of sharp arrows." ”

As soon as Nima's words fell, puffs of green smoke suddenly emerged from the top of the hall, it was poisonous smoke!

Nima screamed: "Quick, listen to my orders, push the stone map!" We must get out of this hall before the smoke poisons us! ”

Nima's brain is like a high-speed computer, quickly reporting the history recorded in various stone maps: "Gongying of Qinzhuang also led five brothers and 7,000 soldiers and horses of the Zhou Dynasty to defeat Xirong and made great achievements; Qin Mu Gongying was assisted by Baili Xi, Jian Shu, Pi Bao, Gongsun Zhi and other virtuous ministers, and became one of the five tyrants of the Spring and Autumn Period; King Yingdang of Qin Wu was determined to win the championship and sent troops to attack Luoyang, the weak capital of Zhou Tianzi. In the Zhou Temple, King Wu lifted Zhou Ding, but he couldn't hold it, and he was injured and died--"

Driven by Bai Xiaofei, Qiao Feng, Xiaopang, appetizer and others, the huge stone maps roared and rearranged and combined, Nima's super brain listed the correct historical order, but the problem is that the arrangement of the stone maps is not a simple one up and down, but according to some special law, when the arrangement is wrong, the stone map will shoot sharp arrows and spears, fly out of the stone axe, and worse, the arrangement will be restarted.

Sweat broke out on Nima's forehead: "Is this the Nine Palace Gossip or the Three Talents of Heaven, Earth and Man?" Or, is it the Vena River map? cough cough cough - "Nima coughed violently, but the poisonous smoke from the ceiling was getting thicker and thicker, her physical strength was the weakest among the people, some couldn't support it, her mind was dizzy for a while, and she looked at the stone map even more confused, carelessly, the command was wrong, and in the roar of the stone map, the arrows were fired all around, and there were no dead ends in a 360-degree all-round.

Bai Xiaofei and the others tried their best to block, and the evil arhat even used his body as a shield to block in front of Nima, so as to protect her safety. But Lulu, Chen Hao, and Sun Xiaohou were injured because they couldn't dodge in time.

Nima was so anxious that tears came out, she regretted for the first time, why she only cared about researching science, and forgot to exercise her body, so that at this critical moment, her body has become the biggest shortcoming - sure enough, the amount of water in a wooden barrel is determined according to its shortest board, no matter how smart her mind is, now she will be smoked to death by a mouthful of poisonous smoke, and even affect everyone.

At this moment, the appetizing milk suddenly rushed to Nima's side, the black snake on his neck opened his mouth and inhaled, the green poisonous smoke around Nima was inhaled into the black snake's body, and the appetizing milk spewed out a breath of true breath at Nima, and Nima suddenly sobered up a lot.

Nima immediately understood, this is the way of appetizing milk to help herself by purifying the poisonous gas and artificial respiration, she did not thank her, just nodded, and once again raised her breath and ordered everyone to push the stone map, just now in a thousand moments, Nima finally realized that this stone map is distributed according to the meridians of the human body, and each stone map represents a Zhou Tian acupoint.

This time, no more arrows were shot from behind the stone figure - it worked!

However, there are too many stone drawings - it is no wonder that the history of the Qin Dynasty is too glorious, just like the history textbook of Yan Huang students, a thick one, which is still as small as possible - and the poisonous smoke on the top has been continuously spewing out, even Bai Xiaofei and Qiao Feng, the two with the strongest skills, feel difficult to breathe.

Finally, a bell rang, and a stone map in the center of the hall shone brightly, it was a picture of a horse herder, there was no king, no general, no virtuous ministers, just a group of happy men, riding on the back of a bare horse, galloping on the grassland - the ancestors of the Qin State, originally the horse wranglers of the Zhou Dynasty, this is the earliest ancestor of the Qin Dynasty.

Behind the herding map, a passage was revealed, and everyone knew that this was the way to live, and rushed forward, Nima breathed a sigh of relief, rushed to the stomach and said, "Hurry up!" ”

The appetizer smiled and suddenly fell to the ground, and Nima found that the appetizer milk was full of blue, and it was actually poisoned! The black snake of appetizing milk has degraded before, from a light snake to a solid black snake, although it has the function of detoxification, but it can't withstand the green poison gas is too much and too strong, and the appetizing milk has to ferry its true qi to Nima, one and two, the poison is extremely deep, and the moment the stone map is opened, it finally can't support it.

Nima exclaimed, hurriedly pulled away the stomach milk, and threw it hard: "Hurry up!" ”

Chen Hao flapped his wings, flew over and picked up Nima, and flew towards the Muma Diagram - because the stone diagram was slowly closing, and the time to open the door was limited!

Chen Hao carried Nima through the stone map, and with a bang, the stone map closed behind his back, and Bai Xiaofei stepped forward: "Where's the appetizing milk?" ”

Chen Hao shook his head, Nima burst into tears, and Bai Xiaofei stomped his feet: "Go!" Their sacrifice must not be in vain! ”

Moving forward along the passage, suddenly cheerful, there was actually a grassland in front of him, exuding the fragrance of grass, and the sky was shining brightly - there was no sun there, but the cave wall was glowing, Bai Xiaofei found that it was a kind of glowing moss similar to the corpse brother dungeon, and the grassland in the depths of the underground grew up under the light of this moss.

Ling Lan sensed it: "There is no ambush here. ”

Lulu rode on the head of the gigantic Becky and pointed ahead, "Look, there's a city there!" Sure enough, in the depths of the grassland, the outline of a giant city loomed into view.

Bai Xiaofei was sad for the sacrifice of Lin Xinyi, ghost sticks, and appetizing milk, but he was also a little dumbfounded when he saw this scene, he had imagined the true face of the Mausoleum of the First Emperor countless times, but he didn't expect that it was actually a city in the grassland - the First Emperor was worthy of being the first cow man who pioneered the Yanhuang feudal system, and even the mausoleum was so incredible.

Bai Xiaofei led everyone to run towards the city, the city is getting closer and closer, and you can already see the tall gatehouse, a tall tree on the gatehouse, a black flag, and a big "Qin" in it.
