Just as he arrived at the airport, Xie Dongya received another call from Meng Feilong, telling him to go directly to the airport's inner level. Meng Feilong had come here on the dragon-group's private jet.

After telling Li Tong to go back, Xie Dongya boarded the special plane of the dragon-group. Other than Meng Feilong, the leaders of Two Groups, Kou Yong and Wen Tianjiu were also present. However, Pei Zhenggang and Shi Teng did not follow them.

Meng Feilong had only told Xie Dongya that they had other missions, but did not specify what missions they had. Xie Dongya did not question him further, but chose to chat with Kou Yong about what might be beneath the Heaven Basin.

The plane flew for two and a half hours before landing at Changbai Mountain Airport. Meng Feilong got a car after landing on the plane, and the four of them immediately headed towards Changbai Mountain.

Changbai Mountain, 2,691 meters above sea level. Although it was not too high, it was definitely not short. The Changbai Mountain had already been built as a tourist area, although it was not the tourist season, there were still a lot of cars going there.

Especially during the past two days, people from all over the country had been rushing over to the Heavenly Lake. However, they couldn't get onto the Heaven Lake even if they came. Since the country sent the Expedition over, they had been under martial law.

When the members of the Expedition disappeared, no one was allowed to go there either. The path to the Heaven Lake was entirely under the control of the troops. Other than people with special status, it would be extremely difficult for an ordinary person to enter.

When Xie Dongya's car reached the foot of Changbai Mountain's feet, two armed police officers immediately went forward to check, and only allowed them entry after seeing Meng Feilong's ID card.

The car could no longer move after walking for another few hundred meters. and the others got off the car and started to climb the mountain. All four of them were Ancient Fighters, so climbing the mountain was very easy for them.

Along the way, there were troops everywhere. Every time they came to a scenic spot, there would be soldiers that would step forward to inquire about it. It seemed that the country also attached great importance to this matter, and it could be seen from the degree of martial law.

When they finally reached the entrance of the heavenly lake, Xie Dongya saw a senior colonel walking towards them with four silver stars on his shoulders. Meng Feilong obviously knew him, and after the two chatted for a bit, Meng Feilong brought Xie Dongya and the others and walked up.

The moment he walked out of the exit, Xie Dongya felt as if the scenery in front of him became clear and bright. In front of him was an extremely huge lake, with cliffs hundreds of meters around it, encircling the lake and its peaks. The mountain peak's shadow reflected on the jade pool in bright colors, and the scene was captivating.

It was said that the Heaven Lake was a precious mirror of Venus, and the two daughters of the Queen Mother compared beauty with the mirror. The eldest daughter lost and threw the mirror from the sky before forming the Heaven Lake.

There were also legends that the Western Queen Mother would occasionally bring the deities to the heavenly lake to play, and there would often be fairies that would stealthily descend to the mortal world to bathe here. However, all of these were just legends. Xie Dongya wasn't very interested in this water monster, but rather, he was very interested in the heavenly lake water monster.

When Xie Dongya was young, he heard that there was a water monster in the heavenly lake in Changbai Mountain. Later on, scientists confirmed that there was nothing in the heavenly lake other than microbes.

But Xie Dongya had always believed in the words of the water monster. There were many things that could not be explained with science. Just like them Ancient Fighters, science could not explain it at all.

"I suspect that those Expedition members have sunk to the bottom of the lake. I want to wait for us to go down and take a look."

After saying that, he opened the bag that the senior colonel gave him and took out a few sets of diving suits. Xie Dongya did not know anything about diving, but his Cultivation Level s had already reached the sky realm so he used them to protect his nose and mouth. As long as the zhenqi was not exhausted, he could always stay underwater.

After changing into their diving clothes, other than Xie Dongya, the rest carried a small oxygen bottle on their backs. Seeing that everyone was ready, Meng Feilong made a gesture to dive, and the four of them jumped into the water together.

The Changbai Mountain's Seraphic Pond was over two hundred meters deep, which was definitely considered extremely deep in the lake. Although the water was deep, it was clear and the visibility was good.

The few of them continued to dive until Meng Feilong made a gesture to separate himself from the water. Xie Dongya used his pure spiritual energy to cover his nose and mouth, and swam towards one direction.

Fang Yuan in the heavenly lake was more than nine miles, if he were to look for it like this, he would probably not even be able to find the entire bottom of the lake in one day. As Xie Dongya moved the Eye of Perspective, he constantly scanned the surrounding situation. Very quickly, he found an extremely tattered set of diving clothes.

Xie Dongya swam to the front of the diving suit and took it into his hands. Not only was the diving suit torn to pieces, it looked as if it had been splashed with sulfuric acid and was riddled with large holes.

Holding the diving suit in his hand, Xie Dongya scanned his surroundings again. Very quickly, he found another set of diving clothes.

While swimming and searching, Xie Dongya found a total of eight sets of diving suits. Carrying a pile of black diving suits, Xie Dongya swam towards Meng Feilong. Very quickly, the two of them clashed against each other, and then Xie Dongya used the pure spiritual energy to summon Wen Tianjiu and Kou Yong.

"This must be the diving suits of the people from Expedition. They coincidentally have eight people." Once he landed, Meng Feilong took off his oxygen mask and said while frowning.

"Could it be that they were attacked and all of them died in battle? "But what attacked them? How could it be possible for the diving suit to turn out like this?"

Kou Yong who was standing at the side picked up a diving suit with a trace of suspicion. At that moment, a golden light shot out from the center of the Seraphic Pond. Furthermore, there was a hint of spiritual energy within the golden light.

"Is that …?"

Looking at the golden light that shot into the sky at the center of the lake, Xie Dongya could not help but ask. However, the other three also did not know what the golden light was sent from. However, one thing was certain: there was definitely something good inside the Seraphic Pond.

"Let's go down and take a look."

After saying that to the three of them, Meng Feilong put on the oxygen mask and jumped into the water. Xie Dongya and the rest did not hesitate, and started swimming towards the center of the lake.

However, not long after they entered the water, that golden light disappeared. At this time, Xie Dongya suddenly felt the pure spiritual energy in his dantian begin to pulse gently, as if it had felt something.

The more he swam forward, the more Xie Dongya's pure spiritual energy throbbed. When he was almost to the center of the lake, the pure spiritual energy in his dantian actually started to move by itself, as if it was attracted by some kind of force.

"What exactly is here?"

Suspicion rose in his heart, and Xie Dongya began to scan his surroundings. Very quickly, he discovered that there was a skeleton about a hundred meters in front of him, and Xie Dongya could clearly feel that there was a faint flow of spirit energy on the skeleton.

Using his finger to point in that direction, Xie Dongya took the lead to swim towards the skeleton. At this time, the pure spiritual energy in his dantian was circulating even faster, as if it was about to break through.

"Whose skeleton is this? There's even spiritual energy? "

Xie Dongya swam to the front of the skeleton and looked up. This was a man's skeleton, perfectly preserved. The skeleton was as clear as white jade and there was a faint golden light swimming on it.

"Eh? "What is this?"

Seeing a small box made of white jade beneath the skeleton, Xie Dongya lowered his body and bent down to pick up the jade box. At this time, a golden Dan Wan was lying within the jade box, and was the size of a dragon eye. Even the white jade box was dyed gold.

"Is this an immortal pill?"

In the past, Xie Dongya had heard that elixirs were golden, elixirs were elixirs Cultivation Level could use their own elixir energy to condense, and the spirit energy contained within them was extremely vast.

Although they were still separated by jade box, Xie Dongya could feel the pure spirit energy emitted from the immortal pellet, and the pure spiritual energy in his dantian was circulating at its maximum speed, Xie Dongya felt that he could break through anytime.

Just as Xie Dongya was staring at the golden Dan Wan in a daze, Meng Feilong swam in front of him and pulled him back with all his might. Just as Xie Dongya pulled Xie Dongya away, a black shadow swept past the place where Xie Dongya was standing.

"Damn, what kind of monster is this?"

When Xie Dongya saw the black figure clearly, he was immediately stunned. Everyone said that there was a monster inside the Changbai Mountain's heavenly lake, but it had never been verified.

The black shadow was a monster. At this moment, it was about 10 metres away from Xie Dongya, looking at them with its fangs bared.

The head of the monster had three heads and two long horns. A pair of eyes the size of a copper bell. They were dark green in color and had a large mouth full of sharp teeth. There were also two thin hairs at the corner of his mouth, making his entire head look like a dragon head.

It wasn't that big, but it was about the same size as a lion. However, this thing's entire body was covered in scales, and those scales even had a faint glow. One could tell that they were extremely hard.

Right now, the monster was only staring at Xie Dongya, it did not care about anyone else. Xie Dongya saw that it was only staring at him, and indicated for Meng Feilong and the others to go first.

After all, their Cultivation Level s were too low and the water pressure was not small, which would restrict their strength. No matter what, he was an expert of sky realm, he had to buy time for Meng Feilong and the others to escape.

Seeing that Xie Dongya had signaled for them to go first, Meng Feilong did not hesitate, and immediately gave Wen Tianjiu and Kou Yong a signal, and headed upstream.

He was very clear that staying here would not help Xie Dongya at all, and would instead become a burden. The monster glanced at the three people who were trying to escape, but did not give chase and stared straight at Xie Dongya.

"Could this thing have attracted it?"

Seeing that Meng Feilong and the other two had escaped, the monster did not have any reaction, Xie Dongya looked at the immortal pills in his hands, and then placed it inside his diving suit.

Once the monster saw Xie Dongya hiding the golden pellet, it roared and rushed towards Xie Dongya. The monster's speed was extremely fast, and within the blink of an eye, it was already more than ten meters away.

After passing the pure spiritual energy onto his hands, Xie Dongya dodged slightly, then jumped a few meters back due to the pushing force of the zhenqi and the water. As soon as he moved away, the monster appeared where he had been standing. After his attack failed, the monster immediately adjusted its body and continued to rush towards Xie Dongya.

"Damn, this isn't a solution either. Sooner or later, I'll have it exhaust itself to death."

Right now, Xie Dongya was in the middle of the lake, so his speed in the water could not even compare to the monster. Even if he couldn't outrun it, he could only fight it head on.

After continuously dodging a few times, Xie Dongya let out a low shout in his heart, and a dense wave of pure spiritual energy immediately flew out from his body, then spread to the surroundings of his body.

With a wave of his hands, Xie Dongya controlled the zhenqi to stir the water around, and then transformed into a water arrow, and shot it straight at the monster.

The water arrow carried the pure spiritual energy with it as it flew towards the monster. The monster seemed to know how powerful the water arrow was and it twisted its body, dodging Xie Dongya's attack.

Seeing that the monster was afraid of its own pure spiritual energy, Xie Dongya immediately shot a dozen of water arrows, causing Qi Qi to attack the monster.

Seeing more than a dozen water arrows flying toward him, the monster hurriedly dodged them. However, Xie Dongya's water arrows were not only fast, they also had sharp corners.

The monster only managed to dodge a few of the water arrows. The remaining seven to eight arrows hit its body. The water arrows were so powerful that once the monster was hit, it immediately let out a painful howl. A few of the scales on its body were also broken, and green blood flowed out from its body.

"And here I thought you were amazing, but it turns out you're only this amazing."

Touching his nose, Xie Dongya smiled. After being injured by Xie Dongya, the monster roared again and again, opening its mouth wide, water ripples emitted from its mouth.

The water ripple formed a circle shape, quickly flying towards Xie Dongya. Xie Dongya's pupils contracted slightly as he waved his hands consecutively and a few water arrows shot towards the water ripple.

"Pfft."

The water arrows collided with the waves and immediately dispersed. However, the monster immediately spewed out another even larger wave, which actually contained a thick zhenqi.
