That was Lu Beichen's reminder to the white-clothed major general on the roof.

While the guards were anxious about the Holy Envoy, Lu Beichen was observing.

There is a word for Taoism in the world, and even the most powerful secret art will have its own limitations. And although the concealment technique is powerful, it naturally has its drawbacks - time difference.

The starlight that humans can see is the starlight of hundreds of years ago. And this so-called hundreds of years is actually a constant number. The time difference between the concealment technique is also a constant number, and it is also something beyond the user's control.

Disappearing and then appearing, the time in between is uncontrollable, but the direction can.

Above the roof, there will be some indescribable movements in some places. And that kind of abnormal movement is a very subtle change, and the human senses are basically imperceptible.

After many observations, Lu Beichen found that the black shadow almost only appeared in four or five directions.

Leng Mingzhe, who was in the confusion, noticed the sound of the prompt at first. It wasn't until the woman appeared in the middle of Yao Shuxing and Gou Chen Xing that he realized that the shouting voice was the right hint.

"Hotaru, Rokka. He's in the northwest direction, ...... there," Lu Beichen shouted loudly, looking a little exhausted.

After hearing this, Leng Mingzhe tried to launch an offensive in the northwest direction.

Boom!

The time was just right, when the black shadow suddenly appeared, and the crossbow arrow reached a centimeter away from the firing target without staggering.

Accurate, 100% accurate, but what about the hit rate?

The arrow did not run straight, at least not as straight as before, so it did not go straight into the chest of the man in black, as one might expect, but slashed across the man's face.

"How can this be?" Lu Beichen wondered in his heart. Legend has it that the Holy Envoy of every shot, how could there be an omission at such a critical moment?

As the crossbow bolt fell, the black veil also fell, and a snow-white face became brighter against the background of the night, but in an instant, there was an extra blood mark.

That's the blood from the bow and arrow!

The woman's hair was instantly blown messy by the strong wind, and there were some tears in those long eyes, which made people feel pity.

It's just that all this, the people under the roof do not see.

Most of them were a little puzzled and puzzled, why did the Leng Holy Envoy, who was famous for his accurate bow and arrows, actually miss the opportunity to kill with one arrow many times this time? But this was just a sudden thought, after all, the body of the demon clan was hard, even if it was a white jade divine arrow, it would be difficult to harm them.

Therefore, it is believed that the Holy Envoy must have a reason for doing this.

Leng Mingzhe looked at the woman who had been cut by a bow and arrow with a bloody mark, although her face was still as cold as frost, there was a trace of uneasiness in her eyes.

"Princess!" there was a wail from the roof, and then suddenly a large figure appeared, in stark contrast to the weak figure with the face pierced.

"Withdraw ......" The huge black shadow let out a roar of rage, and it fell into the air at an extremely rapid speed, and then completely disappeared in front of these people's eyes.

The sky suddenly fell silent.

Lu Beichen looked at this series of events, and for some reason, he felt a little sad in his heart.

Just now, the moment the two black figures landed, he made casual eye contact with the weak black figure. He could see very clearly, it was not as simple as a dark shadow. That huge figure was the demon man who wanted to attack him behind the big banyan tree, Mo Han in Leng Mingzhe's mouth.

And that weak figure, he didn't know or see. Although he didn't have time to see what she looked like, it was easy to see that it was a girl, not too old, and he heard it clearly, the demon man called her princess.

Could it be that this is the legendary demon princess who brought a heavy snow scene to the demons?

The demon princess brought thirteen warriors to invade the holy capital?

But even so, she is also a member of the demon race. Why did he feel a little sad when he watched that scene just now and saw a trace of tears in that girl's eyes?

I don't want to think about it, but I'm a little surprised that it's almost dawn, and I actually watched the battle here for half the night. Lu Beichen saw that the war had ended, put away his unknown emotions, and was about to leave, but saw the white-clothed major general walking towards him.

"Please stay. ”

"What's the matter?" Lu Beichen blurted out, and then felt that something was wrong, so he said again, "May I ask the Holy Envoy for any advice?"

"How do you know?" Leng Mingzhe's tone was always very calm, as if nothing special had happened just now.

Lu Beichen couldn't help but be speechless in his heart, should he say that he was a general or indifferent and ruthless, making the little girl's face hang a color, wouldn't he have some bad feelings in his heart?

Of course, this is just a thought in his heart, and he is naturally not stupid enough to say it.

"Little brother?" Leng Mingzhe looked at the young man in a daze, and shouted again.

"She moved by becoming invisible, and of course I couldn't tell where she was, but I could feel the movement of the hidden space. As long as you judge it and calculate the time point when the bow and arrow will hit the target after it is fired, and the time point when she is about to appear, you can hit it with one shot. ”

"I see. Leng Mingzhe nodded and continued, "Few people should know those direction words. ”

"When I was a child, I thought I had probably seen it, this is a word for reminding the battle, and I remembered it at once, but I didn't expect to use it today, it's just a coincidence. Lu Beichen said slowly, feeling that the holy envoy in front of him had something to say.

Leng Mingzhe is indeed very curious, why are those uncommonly used words so familiar to an ordinary person?

Yaoshu and Gou Chen are the positions of the Yao Shu Star in the east and the Gou Chen Star in the northeast, respectively, while the Firefly Shu and Liujia are the positions of the due west and the North Liujia Star respectively, and the woman in black is hidden in these directions with the help of night and spells.

The reason why he knew these words was a long time ago, from an unknown miscellaneous book. Due to the extremely low popularity, the use of these directional words is a bet that the other party does not know, so it is also what Lu Beichen said - to remind the use of war.

And in today's situation, it is very appropriate to use these directional words, after all, the other party is a demon, how can he know the meaning of these remote directional words in the human race?

However, a human race's holy envoy and a scholar from the mountains actually have a tacit understanding?

"You're not simple. Leng Mingzhe thought about it and said this.

Lu Beichen was a little tired, so he tried his best to suppress his emotions, and said as politely and gently as possible, "What are you suspicious?"

"You're thinking too much. The corners of Leng Mingzhe's mouth couldn't help but rise in a slight arc, as if he was laughing. In fact, he wasn't suspicious of anything. Or, in other words, he was a little more curious and surprised than skeptical.

In addition to being curious about how this young man learned those direction words, what surprised him even more was how a young man who was just a young man with little cultivation experience could make a correct direction judgment in a situation like just now.

He also knew the problem of time difference, but it was too difficult to make a judgment at that time.

"I'm just weird that ordinary people don't know the word for the direction, you know. What's even more strange is how do you know that the shadow is in the direction you said it is, and why are you so sure?"

"Sure? Actually, I'm not sure. Maybe it's because I can feel the movement of that space, so I want to give it a try. Lu Beichen said quietly, yawning unconsciously.

"Give it a try?" Leng Mingzhe's face showed surprise. He never thought that the instruction he had affirmed just now was actually based on Lu Beichen's attempt.

"If you're wrong, it's my life. ”

"If I had guessed wrong, I'm afraid I wouldn't be standing here right now. ”

The two teenagers looked at each other, but the things conveyed in them were completely different. Leng Mingzhe was a playful question, and Lu Beichen replied very seriously.

If it was a gamble just now, it would be better to say that Lu Beichen was gambling with his life. Leng Mingzhe is extraordinary, and his realm is also extraordinary, it is obvious that Fang Cai is just messing up, if he really guesses wrong, he will only be injured.

But Lu Beichen is not necessarily. It is a sin to really hurt an emissary, whether intentionally or unintentionally or by mistake.

So he's gambling with his life.

"Although this is a bet, the Holy Envoy still believes it, don't you?" Lu Beichen said very seriously, his eyes flashing with some light.

"If you have half the ability to protect yourself, you will not always put yourself in danger. Leng Mingzhe stared at him for a while, and he couldn't help but feel some strange emotions in his heart.

He saw a pair of eyes as clear as the bottoming of the lake.

Lu Beichen smiled, looked at the glow in the sky, and said, "It's almost dawn, I really should go back, there are still very important things today." ”

"What's your name?" Leng Mingzhe asked as he saw that the young man was about to leave.

"Lu Beichen. ”

"That's ...... Saved each other?" Leng Mingzhe looked at Lu Beichen's departing back, and asked with a light smile, "Lu Beichen?" ”
