Xue Qinghe transferred the guards guarding the gate of the palace to replace the original guards of the royal Necuri, and surrounded the vicinity, setting up cards at all levels, three steps and one post, and five steps and one sentry.

Originally, the guards in the royal inner library were ordered to all return to the temporary dormitory and hand in weapons and dangerous objects, if it weren't for the fact that the Heaven Dou royal family had no way to restrict the martial souls, they would have to put a restriction on the soul masters in the royal inner library guards.

This is also a reason for the high status of the soul master, the soul master can summon a martial soul at any time, and has complete combat power at all times, which is much more uncertain than ordinary people.

Xue Qinghe carefully scanned the room where the Hanhai Qiankun Hood was kept, looking for all the clues worth recording, and thinking about how to connect these possible clues to those who opposed him.

At this time, an old man in gorgeous clothes passed through layers of scrutiny, strode over, this person is tall, although he is already full of white hair, but his eyes are bright, he is full of energy, and the strong muscles in his arms prop up the sleeves, and he knows that this person is not simple at a glance.

Seeing this old man, Xue Qinghe bent down slightly and saluted, "Uncle Huang." ”

The person who came was the direct clan elder in the Heaven Dou Imperial Family, Xue Taining, who was a control system Contra Douluo with a soul power level of up to eighty-five levels, and he loved to study mechanical mechanisms and soul guides all his life, and he was in charge of the soul guide research work carried out by the Heaven Dou Empire in recent times.

Obviously, Xue Taining, this Contra Douluo, is the direct force of the Heaven Dou Imperial Family, and the Heaven Dou Empire has been able to stand on the Douluo Continent for so many years, in addition to the bias of other big forces and deliberately maintaining balance, the strong strength it has is also an important reason.

Whether there are more and stronger people in the Heaven Dou Imperial Family secretly, and even Title Douluo-level powerhouses, outsiders don't know, even if it's Xue Qinghe, there is no news at all, only when Xue Qinghe takes the throne and becomes the Star Dou Master of the Heaven Dou Empire can he know.

However, no matter how strong the Heaven Dou Empire is, how huge the hidden power is, after their eldest prince was dropped, and the second prince and the third prince were killed one after another, from the fact that they didn't notice it, and took corresponding actions, the Heaven Dou Empire is indeed weakened, and it has not regained its former glory, and only some capable clan elders are left to hold on.

Xue Taining nodded at Xue Qinghe, "His Royal Highness the Prince, don't say much, let me go and have a look first." ”

After speaking, Xue Taining quickly approached the location where the Hanhai Qiankun Cover was stored, and began to check the situation of the security device.

A few decades ago, before the reign of the Emperor of the Snowy Night, the Emperor proposed to renovate the royal treasury in an all-round way, adding many security devices.

Although Xue Taining's strength was not very strong at that time, he was obsessed with specializing in mechanical mechanisms and soul guides, and he was quite successful in this area, so Xue Taining was allowed to participate in this transformation work.

The guards of the Royal Necuri were not built overnight, but were constantly being added and modified.

Xue Taining, who gradually grew up, naturally joined this project, and slowly became the leader of this project, it can be said that the transformation of the royal Necuri's security device has run through Xue Taining's life, in addition to reaching the strength of Contra, he is most proud of the results of this project.

Now that the Hanhai Qiankun Cover was lost for no reason, and the security device in the royal inner library was useless, this made Xue Taining unbelievable and rushed to the royal inner library as soon as possible.

While Xue Taining was inspecting the security devices of the Royal Necuri, Xue Qinghe called everyone who was on duty in the Royal Necuri that night and asked them some questions.

Looking at the group of bloodless people in front of him, a trace of pity flashed in Xue Qinghe's eyes, he knew that the lowest punishment for this group of people was to stab the frontier, and the soul master's words were a little better, and he would be stationed in the frontier fortress, but Xue Qinghe quickly eliminated this pity, he didn't come to do this.

"Who's the director tonight?" Xue Qinghe asked.

The crowd was silent for a moment, and they all looked at the person in the middle, the person who gathered the eyes of the audience was constantly dripping cold sweat, only to see him trembling forward, "His Royal Highness the Prince, it's me." ”

"Okay." Xue Qinghe stared at the director and asked expressionlessly, "Did you find anything strange tonight?" Are there any suspicious people approaching the Royal Neku? ”

The director touched the cold sweat on his forehead, "Back to His Royal Highness the Prince, except for the guards on duty tonight, no one else approached, not even the palace maids." ”

"If it's a strange place, my subordinates found that for a while, the Hanhai Qiankun Cover suddenly emitted a brilliant blue light, and the entire house was covered with circles of blue ripples."

"But," the director hesitated for a moment, "but on weekdays, the Hanhai Qiankun Hood glows, but it's not as bright as tonight." ”

"Other than that, the subordinates, no other anomalies have been found."

After speaking, the supervisor put his head on the ground and waited for Xue Qinghe to fall.

Suddenly brightened?

Xue Qinghe thought about it, since it was different from usual, then there must be something special going on, and said to the supervisor who was kneeling on the ground: "You get up first." ”

"Yes." The director stood up tremblingly, lowered his head, and didn't dare to look at Xue Qinghe.

"Let me ask you again, has this situation been like this for a long time, or has it only lasted for a short time?" Xue Qinghe asked.

The Director pondered for a moment, then replied affirmatively, "It only lasted for a short while, and then it returned to its usual brightness, so we didn't care." ”

"That's it..."Xue Qinghe continued to ask, "Do you remember what time period it was?" ”

"My subordinates remember that it was not long after the music performance began, and it was during the period when the music performance ended." The Director said cautiously.

"Huh." Xue Qinghe sneered, "No one has reported it for so long, you can really do it." ”

"His Royal Highness the Crown Prince is angry!" A group of people knelt in front of Xue Qinghe.

Xue Qinghe brushed his sleeves and said, "What are you doing kneeling!" Get up, tell me honestly what you did tonight, what you saw, and strive to get off lightly! ”

"Those who have meritorious service are not only exempt from punishment, but also receive rewards."

As soon as Xue Qinghe gave the order, the personnel drawn from different agencies immediately rushed up to take away the royal inner library guards tonight one by one and interrogate them separately to avoid their collusion.

After arranging this group of people, Xue Qinghe turned his head and looked at Xue Taining, who was still checking, and waited quietly.

Xue Taining's soul power fluctuations dissipated and no longer checked, Xue Qinghe saw this, stepped forward and asked, "Uncle Huang, what's wrong?" ”

"No." Xue Taining frowned, "I've checked it several times, the protective mechanism is intact and functioning normally, it shouldn't be, there is no reaction at all." ”

Xue Taining muttered, he was originally very satisfied with the protective device he was responsible for, but the reality gave him a blow to the head.

Hearing Xue Qinghe's question, Xue Taining took a deep breath and adjusted his emotions, "There is no damage to the protective device, and there is no trace of human approach." ”

"I'm in trouble." Xue Qinghe sighed.

Later, Xue Qinghe got confessions from others, compiled the information he had collected so far into a book, and took it to meet the Emperor of the Snow Night.

It's late at night, and it's supposed to be a time to rest, but the palace is really brightly lit at this time.

Such an abnormal scene naturally attracted the attention of people in Heaven Dou City, who were all wondering what was going on in the palace, could it be that someone had staged a coup d'état (laughs)?

Prince Xuexing also noticed the strangeness of the palace, and through the inside line placed in the palace, he took a great risk before turning back to a vague news, and the Snow Night Emperor was suspected of getting worse.

Prince Xuexing, who had long guessed whether the Snow Night Emperor was poisoned, was in a hurry, thinking that Xue Qinghe had made a move!

hurriedly went to Dugu Mansion and found Dugu Bo, although Dugu Bo was very dissatisfied with Prince Xuexing coming to disturb him late at night, but in view of the fact that Prince Xuexing had saved him, he would not pursue it.

When he heard Prince Xuexing ask him to go to the Heaven Dou Palace, Dugu Bo refused, he didn't want to participate in the battle of the Heaven Dou Imperial Family, but he did owe Prince Snow Star a favor.

So, Dugu Bo had to take Prince Xuexing and Avalanche to the Heaven Dou Palace, originally outsiders were not allowed to enter the palace, but seeing that it was Prince Xuexing and the Fourth Prince Avalanche, plus Poison Douluo Dugu Bo had the gold medal given by the Snow Night Emperor, after thinking twice, the guards let them go with the consent of their superiors.

Knowing that Dugu Bo was coming, the Snow Night Emperor was also very surprised, this master was very arrogant, why did he come to him?

After several considerations, the Snowy Night Emperor still sent someone to greet Dugu Bo.

Not long after, the three of Dugu Bo came to him under the leadership of the confidants of the Snow Night Emperor.

"Poison Douluo, Snow Star, Avalanche, why are you here?" The Snowy Night Emperor said.

"We are worried about Your Majesty's safety, so we specially invited Poison Douluo to come and treat Your Majesty." Prince Snow Star replied.

Avalanche stepped forward and asked softly, "Father, are you okay?" ”

"I have a heart, I'm fine, after the treatment of the imperial doctors, I'm much better." The Snowy Night Emperor said with a smile.

Dugu Bo saw that the Snow Night Emperor's face was ruddy, and he didn't look like he was about to die, so he planned to go back.

But he was stopped by Prince Xuexing, "Your Majesty Poison Douluo, please stay." ”

Dugu Bo turned around and asked, "What's the matter?" ”

"Please check your Majesty's body." Prince Snow Star said respectfully.

"I don't need to." Dugu Bo frowned, "A group of imperial doctors are here, what's the matter with the Snowy Night Emperor, won't they be able to check it out." ”

"Although the imperial doctors' medical skills are exquisite, they are not as good as Poison Douluo." Prince Xuexing said, "Since Poison Douluo is here, you might as well give Your Majesty a full body examination, which will also relieve the worries of those of us who are courtiers." ”

"Okay, it won't take long anyway." Dugu Bo shrugged his shoulders, "Your Majesty, what do you think?" ”

The Snowy Night Emperor was relaxed, he didn't think there was anything wrong with him, but he was quite happy to have a Title Douluo check his body for him, "It's okay." ”

So, Dugu Bo began to check the body of the Snow Night Emperor, and at first Dugu Bo was very perfunctory, thinking that he would just fool around a few times.

But as the examination deepened, Dugu Bo's face became more and more solemn, and the fluctuation of soul power became more and more obvious.

Prince Xuexing breathed a sigh of relief, Dugu Bo's performance proved his conjecture, that is, the crown prince Xue Qinghe killed the second prince and the third prince, and planned to poison the Snow Night Emperor by giving him chronic poison! He is the younger brother of the Snow Night Emperor, how can Prince Xuexing let such a person who kills his brother and father continue to do mischief!

Seeing Dugu Bo's face change, the Snow Night Emperor couldn't help but become worried, "Your Majesty Poison Douluo, how am I doing?" ”

"Whew!" Dugu Bo took a deep breath and solemnly said to the Snow Night Emperor, "Your Majesty, you have been poisoned. ”

"What!" The Snowy Night Emperor was surprised, not only the Snowy Night Emperor, but also the imperial doctors on the side, the Snowy Night Emperor was actually poisoned? How did they not find out.

An imperial physician stepped forward, "Your Majesty Poison Douluo, are you sure that the Snowy Night Emperor is poisoned?" ”

The other imperial doctor frowned, he was very proud of his medical skills, he didn't think that in terms of medical skills, he would be worse than Dugu Bo, how could it be that he didn't check out that the Snow Night Emperor was poisoned.

Seeing the expressions of the imperial doctors, Dugu Bo explained: "The imperial doctors may be better than the old man in terms of medical skills, but they are absolutely inferior to me in terms of using poison. ”

"The poison in Your Majesty is a mixed poison, it is nothing to eat alone, not even poison, it is normal for you not to check it out."

"But when several toxins accumulate in His Majesty's body, a basic poison will be formed, and His Majesty can be poisoned as long as it is through one more inducement!" Dugu Bo said solemnly.

If it weren't for Dugu Bo's cultivation of the "Heavenly Secret Poison Codex" and his ability to use poison was greatly improved, he would really not be able to deal with this kind of mixed poison.

Now Dugu Bo can easily solve this kind of mixed poison, and can also use the basic poison in the body of the Snow Night Emperor to reverse the trigger, and make a drug that can trace this trigger through some means, and they can catch the poisoner through the drug!

The Snowy Night Emperor was expressionless, his eyes were full of anger, "Just do what Poison Douluo thinks!" I'd like to see which madman did the good thing! ”

The Snowy Night Emperor remembered his tragic death of the second and third princes, and the anger in his heart could not be suppressed.

Prince Xuexing is ecstatic, the fox tail of this snow Qinghe is finally about to be revealed!

At this time, Xue Qinghe, who was carrying a report, appeared in front of everyone, and the Snow Night Emperor told him what had just happened.

"I really didn't expect there to be such a gangster in the palace!" Xue Qinghe said angrily.

Xue Qinghe was afraid for a while, but fortunately, he had already disposed of the sachet he had carried before, and replaced it with an identical sachet without an inducement, and even the backup had disappeared on the Douluo Continent! Otherwise, you will really find out your own head! The plan that has been planned for so many years is almost going to be wasted!

I really didn't expect Dugu Bo to find out!

So, Dugu Bo quickly made a tracking drug, and Xue Qinghe, Prince Xuexing and others were looking for the poisoner in the palace, but unfortunately, they were destined to do useless work, and they stayed up all night, and they didn't even find a single hair of the poisoner.
