Since he is a chivalrous man who robs the rich and helps the poor, it is indispensable to go to other people's homes to commit crimes. But at that time, almost all the people who were petty thieves chose to whistle or imitate the sounds of other animals when they notified their accomplices.

What happened in the end?

Good guys, as soon as someone whistles, there will be catchers coming at full speed.

In this way, the person who is watching wants to remind the person inside, so he has to prepare a new strategy. And this silk thread is an extremely important part of it.

He attached the thread to the door, window and the finger of the stalker, and straightened it. In a tense situation, as long as you flip it, it will make a certain vibration, and it can also remind the people inside that there is danger in a silent situation.

This method originally only existed in Emperor Xuan's mind, but once it was suddenly realized. That's why Emperor Xuan decided to give it a try.

Practice has shown that this is much better than whistling or other means of notification.

"I took advantage of this and left a space for the carpenter to make things that opened directly to the outside. It's not a lot of space, but it's just enough to accommodate a thread. The speed at which this method transmits information is very fast, and of course, this alone is still not as fast as an immortal cultivator. ”

So, in my spare time, I found someone to train a group of people so that they could understand me. ”

If the length is not enough, the broken opponent will fluctuate the silk thread in his hand, and use this to achieve the effect of spreading to the entire palace.

It can be said that there are threads in every part of the palace, but others are not aware of it......

Emperor Xuan called two more people next, judging from the verbal expression, it should be the head of Jinyiwei and the head of Dongchang.

Although these two people were also slightly unconvinced, they were not as obvious as the previous people in the West Factory.

After a few words, the two men were given the order.

"Don't worry, as long as the person you are looking for is still in this Xuandu realm, there will be a result within three days. Don't underestimate the intelligence network of the two factories and Jinyiwei!"

Intelligence Network?

Hearing this, Han Tu frowned and couldn't help but think.

Although immortal cultivators usually do not come into contact with people, they will also try to be careful to avoid revealing their identities.

But the wise will make a mistake, no matter how much they hide it, they can't avoid leaving clues.

If the intelligence network that Emperor Xuan said was really so good, how could he not know about the existence of immortal cultivators?

Han Tu asked the doubts in his heart.

Seeing that Han Tu didn't speak, Emperor Xuan thought that his words had angered the other party, so he didn't dare to bother.

After Han Tu spoke, he exhaled with relief and explained.

"Of course they know about the immortal cultivators, but aren't the people who can live to their age and achieve their position full of ghost ideas? So, they can already see what can be messed with and what can't be messed with. ”

Speaking of this, Emperor Xuan's eyes showed a fierce light.

"To them, immortal cultivators are much more terrifying than me, the emperor. ”

"Oh yes, you didn't notice Gonggong Cao's eyes when he was leaving, did you?"

Han Tu was stunned, not knowing why this Emperor Xuan suddenly mentioned the head of the West Factory.

For Han Tu, it was completely pointless to guard against mortals, let alone observe the other party's facial expressions.

"Why did Emperor Xuan say this?"

Emperor Xuan's eyes narrowed slightly.

"When I said you were a close friend just now, Grandpa Cao's eyes obviously changed. To be honest, I didn't think anything was wrong at first, until I just reacted. ”

Speaking of this, Emperor Xuan paused, and then continued.

"After all, I am the king of a country, and if you want to see me, you have to go through layers of guards. And that Gonggong Cao obviously didn't get the information that anyone wanted to meet me, if you came, your identity would be extremely obvious. ”

"The person who can ignore the guards and quietly enter the palace, who is not an immortal cultivator?"

Hearing Emperor Xuan's explanation, Han Tu recalled what had happened at that time. He frowned slightly, obviously what Emperor Xuan said did have a certain logic.

"Since he already knows that I am an immortal cultivator, why would he still fight against you?"

Emperor Xuan's eyes turned cold.

"That's where he comes in, he guesses who you are, but he doesn't tell you and keeps it the way it was. This is entirely because of the people who want to trap Dongchang and Jinyiwei. ”

No wonder he saw an unfamiliar face, but he didn't ask questions, I'm afraid he guessed it a long time ago. He wants to borrow your hand to eradicate the other two forces. ”

Han Tu chuckled and shook his head.

"Emperor Xuan laughed, why would Han be so good at doing such a boring thing?"

Emperor Xuan sighed.

"In the next few days, if you are still in the palace, he will definitely prompt you to have a conflict with the other two major forces, and use you as a knife to eradicate the other forces, so that the family will dominate. ”

Han Tu's brows furrowed slightly, and his eyes turned cold. If this person is really so boring, he doesn't recommend sending the other person on the road directly.

Emperor Xuan saw the change in Han Tu's expression and understood that he had spoken too much, so he hurriedly changed his words.

"Actually, this is not a good thing, then after guessing your identity, Gonggong Cao didn't dare to slack off in finding someone after all, and tried his best. In this way, I am afraid that it will not even be three days before you can have news of your best friend. ”

This is one of the few good news in this conversation, Han Tu nodded, and acquiesced.

As long as Gonggong Cao doesn't go too far, then he will turn a blind eye and don't delve into it.

Because the time was not early, Emperor Xuan arranged a place for Han Tu to stay.

Externally, it is claimed that Han Tu is the new imperial doctor who entered the palace to avoid unnecessary trouble.

What people didn't expect was that Emperor Xuan's seemingly well-intentioned behavior added a lot of trouble.

Han Tu didn't have the habit of sleeping in an unfamiliar place, so he still chose to use cultivation instead of sleep.

As long as the method is done properly, the effect of cultivating overnight is even far greater than sleep.

As soon as Han Tu entered the room, he felt that countless eyes were staring at him. Moreover, the owners of these eyes are also divided into different forces.

Aside from the West Factory, among these spies who are responsible for keeping an eye on Han Tu, there must be people from the West Factory or Jinyiwei.

However, in terms of Han Tu's identity and cultivation, how could he take these mortals to heart?

He gradually closed his eyes and entered the cultivation, and the aura around him also turned into a little blue light, which was inhaled into his body.

Fortunately, the spies didn't go deep into the room, otherwise they would have been treated like immortals. After all, how can anyone who has such means be mortal?

There was no word all night, and it was dawn in the blink of an eye.
