Hua Banxue was rescued by the empty line at the time of crisis. The empty line took them to a safe place and warned them somewhat solemnly.

Hua Banxue pursed her lips and didn't speak, waiting for the introduction of Kong Xing.

Kongxing shook his head helplessly and said, "You think I'm alarmist? His face became serious again, and he said, "Don't think that one of you is a stone reader and the other is a messenger, and you can travel the world peacefully. There are many other beings in this world that you, not even us, can easily touch. Then he told the big secret about the crystal.

As Hua Banxue guessed, this crystal is the relic left by the Langmu people, and it is also the core material of Yuncheng's release of the protective shell - Yunjing.

"Since it's the substance of Cloud City, then you must know the relationship between it and the letter stone?" Hua Banxue asked.

"Of course. The close proximity of the Faith Stone will cause these cloud crystals to temporarily fail. Similarly, the letter stone also receives its influence. You should have discovered this property, too. "However, this cloud crystal is an excellent defense material except for the influence of the letter stone, and it is an extremely valuable substance because it does not exist naturally on the earth today. ”

Hua Banxue nodded, she confirmed her guess in her heart - Yun Cheng didn't want to collect the letter stone, but was subject to the balance between Yun Jing and the letter stone. At the same time, she also thought that Kongxing's anger just now was a rush to recover Yun Jing to prevent the "baby" in her family from flowing out, and she couldn't help but have some contempt for Yun Cheng in her heart.

"Master Skywalker, if this thing is so dangerous, why did you let us risk our lives without telling us?" Although Hua Banxue is a gentle person, she almost got into trouble when she thought that she was following the instructions of the empty line all the way, and she couldn't help but feel indignant in her heart.

When Kongxing heard this, his original momentum froze, and he smiled bitterly and said, "This ...... That's really not what I intended. He was a little embarrassed: "Actually, I didn't know this thing was there." ”

It turned out that the two of them got this crystal out of the surprise of Kong Xing and Yun Cheng, and it was indeed not the original intention of Kong Xing to guide them to the abandoned base of Guanjiang.

Originally, Kuxing just wanted them to feel the power of nuclear energy, and by the way, they found a letter stone. But Cloud City had no idea that such a dangerous object was hidden in this base.

The reason why this crystal is dangerous is not because of its subtle relationship with the letter stone, but because it can trigger some kind of existential reaction. The sudden release of energy from the crystal and the ground shaking caused by it were the harbingers of the reaction.

"Fortunately, I arrived in time to contain Yunjing's anomalous reaction, otherwise, the disaster of more than ten years ago would be repeated here." Kuxing's tone became heavy.

Hua Banxue also temporarily put away her dissatisfaction with Yuncheng and Kongxing, and she also heard the seriousness of the problem in Kongxing.

"Have you ever been in a similar situation before?" Hua Banxue tried to ask.

The blank line's expression looked extremely embarrassed. After a while, he seemed to have made up his mind and said, "That's right. The previous disaster here was Cloud City...... Indirectly. ”

Hua Banxue couldn't believe her ears. She asked in a trembling voice, "You mean that Cloud City caused that great earthquake?" ”

Kuhang nodded with difficulty and said, "It was purely an accident. It was after that time that we realized that there was a certain dangerous property of the clouds, so this time we came to prevent the recurrence of the disaster in time. ”

Faced with the angry Hua Banxue and Xiaoshi, Kongxing repeatedly emphasized that the accident many years ago was purely accidental.

Hua Banxue's eyes were cold, and she asked, "If you come a little later, the disaster will happen again?" Haven't I become a sinner? ”

Even the little stone, who had always admired the empty line, stared at him with a resentful gaze.

Kongxing's face turned red, and it was difficult to answer.

Hua Banxue asked again: "With your Cloud City's ability, you can't avoid this danger?" Could it be that this reaction has something to do with Gurok? ”

Kongxing looked strange, and he stopped talking.

Hua Banxue sneered: "Master of the Sky Line, or rather, there are some secrets that cannot be told here?" ”

Kongxing's face changed, and a sharp light flashed in his eyes. Then, with a long sigh and a wave of his hand, a white light flashed, faintly forming a barrier beside the three of them.

Kongxing beckoned Hua Banxue and Xiaoshi to sit down, and then slowly told a big secret.

Cloud City is the last fortress and ruins of the Langmu people, which has existed in this world since ancient times. When the original messenger discovered it "by chance", it was empty. Although all sources indicate that this is the work of the Langmu people, no one has ever seen the Langmu people, and no one knows why the Langmu people disappeared from the earth out of thin air.

Successive messengers have done a lot of research, but they still can't know the whereabouts of the Langmu people. However, as the messengers developed and learned more about Cloud City's functions, they discovered that although Cloud City was a battle fortress against the Ancient Rocks, another important mission of its existence turned out to be to awaken some kind of existence. And this existence is most likely the real owner of Cloud City, the sleeping or sealed Langmu Relics.

I don't know when it began, the messengers who originally worshipped the Langmu people had a tacit understanding. Intentionally or unintentionally, they did not carry out this mission of Cloud City, and even deliberately let Cloud City avoid the location of the Langmu Relic Clan that had been discovered.

"We speculate that the way to awaken that being shouldn't be difficult, as long as Cloud City stays in the Sleeping Place, the material that releases the shield, Cloud Crystal, will automatically release a signal. This kind of signal is the special field force technology of the Langmu people, which can cause resonance with that being, and then awaken it. Kongxing's eyes were full of jealousy.

Hua Banxue nodded, she understood the delicate situation of Cloud City.

"After all, once you have transcendent power and status, you can't easily give it to others." Hua Banxue said with some pity and some mockery.

Kong Xing sighed and said, "Miss Hua sees it very accurately. We tacitly accept this, but we also convince ourselves with the argument that 'those who are not of our race will have different hearts'. After all, the Langmu people are an existence that we don't understand, after all, the current masters of the earth are human beings. ”

Hua Banxue said: "Master, you tell us such a big secret, don't you be afraid that we will use this cloud crystal-" She looked at the green crystal in her hand and said, "Wake them up for you?" ”

Kong Xing smiled, and he said, "I'm sure Miss Hua won't." After all, we already have a formidable enemy like Ancient Rock, and we can't afford to add new trouble. He was very sure of Hua Banxue's determination to protect this world.

Hua Banxue nodded and said, "That's right." But have you ever thought of using the power of the Langmu people to fight against the ancient rocks? Like in ancient times? ”

Kongxing shook his head and said, "We Chinese say that if you go outside, you must first be inside." If there is uncertainty in the family, there is no peace of mind to fight against foreign enemies. ”
