On the top of Yunwu Mountain, Yang Xuan stood with his hands in his hands, looking at the brilliant lights of Pinghai City under his feet.

The mountain breeze is clear, the sea of clouds is swinging, and the flat sea under the night is particularly quiet at this time.

Under this quiet prosperity, no one knew that a great catastrophe was coming.

"General, Dr. Zhang Chengming is here. Li Na appeared behind Yang Xuan and gently put on a coat for Yang Xuan.

"What is he doing at this time?" Yang Xuan asked.

"It seems to have made a breakthrough in the study of that triangular metal. Li Na thought for a moment and said.

Yang Xuan was slightly stunned, and then a glimmer of light appeared in his eyes.

Before the retreat, he handed over the two immortal treasures on his body to the Beijing Academy of Sciences for them to study, but he didn't expect that until now, there was no news.

"Let him come up. Yang Xuan nodded.

After Li Na left, not long after, Zhang Chengming jumped several times and climbed to the top of the mountain.

Although the clouds and mist are not high, the top of this mountain is also steep, if it was placed in the past, whether Zhang Chengming could climb up or not, it is still two words, but now, the physical fitness of the entire human race has made great progress, and Zhang Chengming has also benefited from Yang Xuan's genetic evolution liquid, becoming like a previous martial arts master.

"Professor Yang is so elegant, back to the top, a glance at the mountains, standing here, the entire Pinghai at a glance, really freehand. Before anyone arrived, Zhang Chengming's voice had already come.

Yang Xuan smiled slightly, but did not turn around and said, "Dean Zhang is a busy man, why do you have time to come to me today?"

Zhang Chengming walked to Yang Xuan's side, followed his example and looked at the brightly lit Pinghai, and sighed before saying: "With Professor Yang's words, we must not break our legs." ”

Yang Xuan shook his head angrily: "I'm afraid you are in pain and happy." ”

Zhang Chengming laughed: "Those who know me are no better than Professor Yang." ”

In fact, at the beginning, Zhang Chengming was still a little wary of Yang Xuan, but as time went by, slowly, he had regarded Yang Xuan as a teacher and friend, and from the bottom of his heart, there was a kind of respect that he couldn't explain.

After laughing, Zhang Chengming's face showed a solemnity, and said: "The things you handed over to us have a little eyebrows, you said that these two things are very important to you, I didn't dare to delay, and I rushed over overnight." ”

Yang Xuan nodded and said, "Thank you!"

"You're welcome. Zhang Chengming shook his head and said: "We have invested a lot of manpower and material resources in these two things, in fact, thanks to your technology, we finally have a little breakthrough." ”

"Let's talk about it!" Yang Xuan nodded.

"These two things are clearly from the hands of a higher civilization, and according to our research, we have found that there is a power we do not understand, and this power is so vast and advanced that it once made us tremble. Zhang Chengming's face was serious.

"I know, from the very beginning, I told you that this thing is a weapon, a weapon that you can't understand, the key is how to use it?"

Zhang Chengming nodded: "After a lot of experiments, we finally found a little eyebrow, among these two weapons, there is a very strange ...... Well, it could be a lock, a lock, you know, it's that its power is locked and needs to be unlocked to use it. ”

"Unlocked?" Yang Xuan frowned: "How to unlock?"

"This is also the direction of our key research, and it once put us in a predicament, and it was only recently that there was a little breakthrough. Zhang Chengming said.

"Tell me about it. Yang Xuan looked at him.

Zhang Chengming took out Yang Xuan's two immortal treasures from the small box in his hand, and after solemnly handing them over to Yang Xuan, he said: "The key to unlocking these two weapons is likely to be some kind of gene, or, some kind of established program, in other words, these two weapons are designed by people, and only their real owners can unlock them with their own genes or other things." ”

Zhang Chengming explained with great difficulty, and it could be seen that he was indeed attentive.

Yang Xuan frowned and said, "Need to unlock it?" But I told you that there are actually six of these weapons, and the other four are in the Penglai World, and people over there can use them." ”

Zhang Chengming nodded and said: "We have also thought about this problem, because there is no sample to study, so we made a bold hypothesis. ”

"What?" Yang Xuan asked.

"That is, let's assume that this is a double lock, and under certain conditions, its first lock will be opened, and the user will be able to use some of its powers. Zhang Chengming said.

Yang Xuan fell into deep thought.

Gene lock, set program, set conditions?

Zhang Chengming smiled bitterly: "I can only help you get here, this kind of high-level civilization is really not something we can understand thoroughly, alas...... , forget it, it won't help you anything, I'll go first, you can contact me if anything, I promise to be on call. ”

Yang Xuan didn't seem to hear Zhang Chengming's words, and was still pondering.

Zhang Chengming wanted to say something, but after he stopped talking, he finally turned into two words: "Take care!"

With that, he turned and walked away.

The mountain breeze is blowing, it is late autumn at this time, the crooked neck tree on the top of the cloud mountain is blown by the wind, and the dead leaves are like elves in the night, constantly flying around Yang Xuan's body, and then falling to the ground, it will be stationary, becoming the fertilizer of the tree in the coming year.

The so-called fallen leaves return to their roots and return to their origins, which is probably the same.

"General, let's go back. Li Na gently took the dead leaves on Yang Xuan's shoulders and said.

At this time, the night is darker, and there are dark clouds in the sky. The remnants of blood appeared and disappeared in the clouds, adding a trace of residual brilliance to the world, but making the lonely Cloud Mountain even more deserted.

The dead leaves swept across his face, and after a long silence, Yang Xuan let out a leisurely sigh: "You said that this fallen leaf came from the tree, and finally made fertilizer for the tree, what are you asking for in this life?"

Li Na was slightly stunned, looked at the dead leaves on the ground, and hesitated: "I don't know, maybe they don't have any pursuits, just birth, growth, then falling, death, that's all." ”

Yang Xuan smiled dumbly, changed the topic and said, "By the way, I haven't seen you mention your family, what about your family?"

A trace of sadness flashed in Li Na's eyes, and she said, "General, like you, I have no family, and I am also an orphan. ”

Yang Xuan said apologetically: "I'm sorry. ”

Li Na smiled and said, "It's okay, it's been so long, it's been okay for a long time." ”

Yang Xuan thought for a while and asked, "Haven't you looked for them?"

Li Na smiled: "I have found it, and I have found it, but it is only two lonely graves, and there is not even a tombstone." ”

Yang Xuan was indifferent.

Unexpectedly, Li Na, who usually looks cold, has such a tragic past.

Li Na paused, and after glancing at Yang Xuan, she said: "Actually, we have also investigated your background before, but the strange thing is that no matter how we investigate, even digging three feet into the ground, we can't find a trace of the general's family." ”

Yang Xuan smiled and said: "I was born on the night of a thunderstorm, and I was rescued by the old dean, if it wasn't for the old dean, I might have died a long time ago, the name Yang Fan, or the old dean chose it for me...... Huh? wait......"

As soon as he said this, Yang Xuan was suddenly stunned, and a thunderbolt exploded in his mind.

Yang Fan!?
