The water surface of Hulun Lake is calm, reflecting the blue sky like a mirror.

Lu Hao's gaze was as calm as the lake, just standing quietly by the lake, staring at this calm lake. Within a hundred kilometers, only this large lake has not been explored, could it be said that the crystal skull will be in this large lake? In other words, where will Genghis Khan's mausoleum be?

Lu Hao felt a little incredible, there is no historical material that records that Genghis Khan's mausoleum will be in the big lake.

Spiritual power hovered above the surface of the lake, and suddenly plunged into it.

Five-meter ...... 10 meters ...... Soon Lu Hao's spiritual power touched the bottom of the lake and continued to face down.

Twenty meters ...... Thirty meters...... Fifty meters......

Lu Hao's spiritual power directly covered the entire bottom of Hulun Lake, and even penetrated to a depth of fifty meters, but he still didn't find anything.

Lu Hao's brows furrowed. A mausoleum, no matter how deep it is, will not exceed more than ten zhang, that is, about thirty or forty meters, and it is rumored that Genghis Khan's burial is only ten zhang deep.

Whatever, keep exploring!

Lu Hao gritted his teeth, and his spiritual power penetrated down again, sixty meters ...... Seventy meters...... Ninety meters ...... Ninety-five meters......

The more the density of the soil is facing down, the slower Lu Hao's spiritual power penetrates, Lu Hao's eyebrows can't help but wrinkle, he can easily penetrate a hundred zhang distance in other places, why is this ......

Lu Hao thought of a possibility, some emperors' mausoleums will always have certain protection measures, such as the Mausoleum of Qin Shi Huang, the mausoleum is wrapped in a layer of flowing mercury.

When Lu Hao detected ninety-nine meters.

Airplanes......

Lu Hao's spiritual power suddenly felt a burst of emptiness.

"Found it!" Lu Hao's eyes suddenly burst into a bright light. But in the blink of an eye, it was replaced by a touch of shock.

"This ...... How is this possible? Lu Hao cried out in a lost voice.

"Woo...... Boss, what's impossible? What did you find? The voice of the gray Jiao came from mid-air, and then directly turned into a streamer and appeared on Lu Hao's shoulder.

Not far away, Yan Juan's three daughters rode three jujube red horses and trotted all the way to this side.

"Honey, why are you running so fast?" As soon as she jumped off the horse, Yan Juan complained. Lin Jie and Yang Meiyun also looked at Lu Hao with a complaining face.

"I can't help it, the black wind is too wild, and it was not easy to tame!" Lu Hao smiled wryly.

"By the way, what about Black Wind?" The three girls looked left and right. I never saw the shadow of the black wind. Especially Yang Meiyun, her pretty eyes can be described as shining.

A sharp whistle came from Lu Hao's mouth. There was a sudden sound of horses' hooves in the distance, and a black figure was like a whirlwind, from far to near. It's blazing fast!

Running in front of Lu Hao, he suddenly stood up and snorted. The big head rubbed on Lu Hao's arm affectionately.

"It's so spiritual! Do I ride a lap? Yang Meiyun looked at Lu Hao with big eyes flickering, although she liked Hei Feng, she knew that Hei Feng's temperament was too strong, and now she was just serving Lu Hao alone, if she touched it herself, I was afraid that she would definitely give herself a hoof.

"Of course, Black Wind. I'll run a little steady! Lu Hao patted its head, and a white eruption suddenly erupted from Hei Feng's nose, although he was reluctant, he still did not disobey Lu Hao.

"Well, this donkey is quite arrogant!" Gray Jiao came over. didn't show a trace of breath, just stared at the black wind with big eyes.

Seeing the pocket version of the gray Jiao, Hei Feng naturally would not act aggressively, until the gray Jiao came to Hei Feng and wanted to land on its head, Hei Feng was suddenly furious, and he snorted at the gray Jiao, if it weren't for the gray Jiao to hide quickly. It will definitely be bitten by the black wind, and although it will not be hurt, it will definitely not be able to get over the face.

"Woo...... You donkey, dare to bite me! Gray Jiao was furious, and suddenly his body exuded the majesty of a divine beast, and the vigilance in Hei Feng's eyes suddenly increased, and his hooves ploughed the ground. The pure eyes were full of uneasiness.

"Yo he, it's quite supportable!" Gray Jiao's face was a little unbearable, and he was about to enlarge his body but was stopped by Lu Hao. If it is allowed to make trouble like this, it is estimated that there will be news reports the next day that there is a water monster in Hulunbuir Lake.

"Boss. Why are you stopping me, it's just a donkey, and if you really move your mouth towards this seat, it's just a crime! The gray Jiao screamed, very upset with the offense of the black wind.

"Okay, what are you doing with it? It's just instinctive. I have made some discoveries! Speaking of this, Lu Hao's voice lowered.

"What? Did you really find out? Gray Jiao suddenly shouted, he didn't expect Lu Hao to find out so quickly.

"Did you find the Crystal Skull?" Yan Juan's attention was also attracted by Lu Hao.

"Not yet, but it's here." Lu Hao said confidently, "The crystal skull has moved, and I did find a mausoleum in this place. It's just that the crystal skull hasn't been found yet, so you're here! ”

"Is it Genghis Khan's Mausoleum?" The eyes of the three girls suddenly lit up, although the wealth is amazing now, and there are all the treasures of the original Caribbean pirates, but for these adventures and treasure hunts, the three girls are still extremely enthusiastic.

"Not sure yet." Lu Hao shook his head, "The tomb is under Hulun Lake, a hundred meters from the ground, and the shape layout is a bit like an egg. Moreover, the periphery of the mausoleum is wrapped in a special substance, which is ten meters thick, like an eggshell! Lu Hao said as his spiritual power probed into it again.

"100 meters? How could it be buried so deeply! The three girls were shocked.

"But even if it's a crystal skull inside, how do we get it out?" Lin Jie said dejectedly, at a distance of 100 meters, even if it is a big hole, it will take a long time!

"I found it, it's indeed Genghis Khan's Mausoleum!" Lu Hao suddenly shouted, and his eyes suddenly lit up. Lu Hao's spiritual power swept across the entire tomb, and found a large bow in a tomb where a coffin was stayed, and the three big characters of Temujin were engraved in Mongolian characters on the big bow.

Genghis Khan's original name was Temujin, who was good at riding and shooting, and once bent his bow to shoot eagles. This big bow once accompanied Temujin in the southern and northern wars, and grew from the leader of a tribe to a heavenly khan, and all tribes respected the same! The Mongolian Iron Horse is even more horse-riding in Europe, which is called "" by Westerners!

Seeing Temujin's hard bow, Lu Hao was not excited, what really excited him was that a crystal skull on top of Temujin's coffin was exuding a warm luster, which made people feel the urge to hold it in the palm of their hands.

"Is it really here?" A hint of surprise flashed on the faces of the three girls! It's getting closer and closer to collecting all the crystal skulls.

"Hmm!" Lu Hao nodded, "But it's a hundred meters below!" A trace of dejection flashed on Lu Hao's face. Although his mental power is amazing, he can even directly open up a passage, but in this way, I am afraid that the movement is definitely not small. Lu Hao was embarrassed!

"This is easy to do, isn't it a distance of 100 meters!" The corners of Lin Jie's mouth flashed a hint of curvature, and a hint of wisdom flashed in her big eyes.

"Oh? Lin Lin, do you have a way? Lu Hao's eyes suddenly lit up.
