After entering Beihai City, Bai Qi immediately handed over the three pretender masks to Adrian and ordered him to arrange for Nightingale to find a way to infiltrate the Beihai Palace.

With the Pretender Mask, it is very easy to infiltrate the royal palace, but how to maximize the effectiveness of these three masks and minimize the chance of the nightingale being exposed is something that needs to be considered by them in the long run.

Bai Qi didn't care about the loss of the nightingale, however, there were only three pretender masks, and he couldn't stand losing one.

On the way to Beihaiwei, Bai Qi took advantage of the time to rest, held countless meetings, and after some discussion, everyone felt that it was better to combine the pretender mask and the eavesdropping device to collect information to the greatest extent.

The Pretender Mask is just a tool to place eavesdropping devices in some key locations in the Beihai Palace, and the real information is obtained through eavesdropping, rather than allowing the Nightingale to steal directly with the Pretender Mask, which undoubtedly greatly reduces the probability of the Nightingale being discovered, and the efficiency of intelligence collection is far from being comparable to manual eavesdropping.

Although the Nightingales are all trained as spies, they are all Westerners, and even with the Pretender Mask, it is almost impossible to play an Oriental for a long time without being detected.

Over the next few days, the Nightingale, led by Adrian, went into action.

The monks also have spells such as stealth, so the Beihai Royal Mansion has a lot of special mastiffs to prevent outsiders from sneaking in.

This is a kind of dog known as the ghost mastiff, born with a spirit nose, which can not only smell yin and yang, drive away ghosts, but also sniff through the monk's stealth spells.

At the beginning. The nightingale didn't know how powerful this ghost mastiff was, and sneaked into the palace. was broken by a ghost mastiff and almost lost manpower.

This ghost mastiff is powerful. But there is a bad thing, that is, it is extremely fierce, except for the owner, no one is allowed to get close, and it looks ugly and ferocious, and the barking sound is also breathtaking, often frightening the female dependents attached to it, so this ghost mastiff will mostly be tied up during the day, and only at night will be led out by the guards who specialize in dog training.

After knowing how powerful these mastiffs are. The dark walkers did not dare to sneak into the palace at night, even during the day, in some key places of the palace, such as the main hall of the council, the study room where Beihai played, etc., there were ghost mastiffs patrolling around day and night.

Therefore, even if the nightingale sneaks into the palace during the day, they cannot get close to these core places, and repeatedly hit the wall. Adrian gave up on sending people to infiltrate the palace and instead collected information on the periphery.

However, this time, Adrian once again scattered a large number of Darkwalkers into the Beihai Palace, and their mission was to observe the activities of several of the most important figures in the Beihai Palace. Especially the King of the North Sea himself.

According to the plan they had discussed, Adrian had to figure out the activities of the North Sea King and several other important people in the palace as soon as possible, so that he could figure it out. Bugging devices are installed there to make the most sense.

Three days later, Adrian took two of the best nightingales with them the materials they had collected for three days. Infiltrated the palace.

The three of them sneaked up on the palace hall, and Adrian transformed into the King of the North Sea by relying on the mask of the Pretender. Walking towards the main hall of the council, although the ghost mastiff guarding the hall barked non-stop, they were desperately pulled by their terrified master.

Adrian swaggered into the core of the Beihai King's Mansion and installed a bugging device under the Beihai King's white tiger seat. And at this time, the real King of the North Sea was patrolling the barracks.

Adrian and the two Nightingales covered each other and installed bugs in the Great Hall, the study of the King of the North Sea, the signing room, and even the bedroom.

Among these places, the study is the place where the King of Beihai spends the longest time in the palace, unless it is a formal court meeting, usually small-scale meetings are held here, so Adrian not only installed eavesdropping devices here, but even installed camera devices.

In the next few days, Adrian took advantage of the opportunity of several important people in the palace to go out, infiltrated the palace, and installed a lot of eavesdropping equipment.

Bai Qi and the others were not idle, each of them held a receiving device, and listened to every move of the Beihai Royal Mansion day and night.

The hard work paid off, and about a week later, Bai Qi and the others finally heard useful news.

On this day, it happened to be Bai Qi's turn to listen to the study of the King of Beihai, and the King of Beihai met here with a figure who seemed to be the steward of the palace, and from the conversation between the two sides, Bai Qi probably learned that the steward had just returned from Penglai Kingdom.

As soon as he heard about Penglai Kingdom, Bai Qi suddenly came to his senses, and listened carefully, this steward seemed to be on the order of the King of Beihai to go to Penglai Kingdom, and find a way to meet a certain deacon of Yulong Dao, and the other party dragged him back with a letter.

From the conversation between the two, Bai Qi heard that although this person was only the manager of the palace, his status was not low, and the king of Beihai was quite polite to him, it seemed that this person was in charge of quite important things in the palace, if it weren't for the knight who lost the deacon token, there would be absolutely no need for this person to come out.

This person is indeed the steward of the Beihai Palace, but unlike the housekeepers and other domestic slaves of the palace, this person is a member of the Beihai Royal Family, who is specifically responsible for preparing for the Beihai King to worship the Dragon Dao, this person's status in the Beihai Royal Mansion is only higher than the four generals under the command of the Beihai King, and for the Beihai Palace, it is as important as keeping the territory of Beihai Prefecture to make a good Dragon Dao.

It is precisely because this person is in charge of spiritual materials that he has been going back and forth between Penglai Kingdom and Beihai Prefecture for many years, and the low-level deacon token that was lost by the knight has been in the hands of this person for a long time.

Due to the invasion of the Wuhe tribe and the harassment of the horses in the North Hengshan Mountain, the preparation of spiritual materials in the Beihai Royal Mansion this year has not been going well, this steward has been busy with this matter recently, and he really can't leave, so the King of Beihai asked for the deacon token from him and handed it to the knight, but he didn't expect the knight to lose the token along with his own life.

Lost the low-level deacon token, and the senior deacon token was very important, and he didn't dare to give it to others easily, so the king of Beihai had no choice but to send this steward who was accustomed to running the Penglai country to go out in person and contact the second brother of the king of Beihai.

There is indeed a way for this steward, there is no deacon token, he waited outside the mountain gate of the Royal Dragon Road for seven or eight days, and finally sent the news to the inside of the mountain gate of the Royal Dragon Road and to the hands of the second master in his mouth.

The steward also handed over a letter to the King of the North Sea.

After reading the letter, the Beihai King's expression was quite complicated, and finally turned into a sigh......

Observing this scene, Bai Qi immediately contacted Adrian, who had been waiting near the Beihai Palace, and asked him to find a way to steal the letter.

After receiving the order from Bai Qi, Adrian sneaked into the Beihai King's Mansion and took a picture of the letter when the Beihai King went to sign the detention room. (To be continued......)
