Advance City is the first prison in the pirate world, it is located at the bottom of the sea, the security is extremely tight, the prison is imprisoned are some felons, it is very eerie inside, there are all kinds of monster jailers and video phone bugs to monitor, a large number of warships are parked outside the prison, and there are a large number of large sea kings on the bottom of the sea outside the prison. Therefore, the promotion city has the name of "copper wall and iron wall". From the establishment of Advance City to the outbreak of the top war, only the legendary pirate "Golden Lion" Shiki successfully escaped from prison, but even a sea thief like him paid a huge price when escaping from Advance City, that is, he cut off his locked feet.

Now that the top war is about to break out, the fuse of this war, Potcas.D. Ace, is imprisoned here, so at this moment, the defense of the city is several times stricter than usual, even if Ling Chen, who understands the world of pirates, is a little helpless, and can only turn to Hawkeye, who has the title of "King Seven Martial Seas".

"You want me to take you to Advance City, you want to rescue Porkas D. Ace before the war begins?" Hawkeye was also stunned by Ling Chen's idea of going to advance the city, as the king of the Seven Martial Seas, he was quite clear about how strict the defense of this advance city was. Not to mention that now is a special moment to imprison Ace, even if he is usually very well defended, with the strength of the world's number one swordsman, there is little hope of going in to save people, Ling Chen wants to save Ace at such a moment, it is tantamount to killing himself.

"I'm going to give it a try!" Ling Chen didn't hide it, and directly said his plan.

"Give it a try...... it's so easy to say, do you know what the Advance City is!" This casual attitude towards Ling Chen. Hawkeye was also a little dissatisfied in his heart, secretly saying that this kid was too arrogant.

"Of course I do. The first prison of the world government, except for the Golden Lion - Shiji's predecessors. No one has ever escaped from prison yet, but I still want to give it a try! Ling Chen said very seriously, with an unchangeable resoluteness in his tone.

"This ...... Okay, but I'll only have to take you into the port of Advance City, and you'll have to do the rest. Seeing Ling Chen's expression so seriously, Hawkeye was also quite surprised, and at the same time, he was a little more curious, ready to help this little ghost once, maybe he could bring him unexpected surprises.

"Just getting to the port is enough. Thank you, Mihawk, and I will repay you twice as much when I have the opportunity in the future. "I am also quite grateful to this Hawkeye for taking him to advance into the city, although it is only to take him into the port, but this is enough for him.

You must know that this Advance City can become the first prison in the pirate world, because it is located at the bottom of the sea, and has masters like Magellan inside, various monster jailers and video phone bugs to monitor it, and there are a large number of warships guarding the port outside, and there are a large number of large sea kings on the bottom of the sea outside the prison. Such a tight defense made him known as the "Copper Wall".

However, this is an impregnable wall for most masters in the pirate world, but there is a huge loophole for Ling Chen, that is, the defense of the seabed.

Because the super masters in this pirate world are generally those who use the ability of Devil Fruits, and the ability is a landlubber who is disgusted by the sea. It is simply impossible to move on the bottom of the sea. Therefore, the world government also thinks that since there are a large number of large sea kings guarding the surrounding city, and it is the seabed that cannot be moved by the able, there is no monitoring phone bug installed. If Ling Chen enters the Advance City from the bottom of the sea, that is, from the outside of the Advance City. The likelihood of success is undoubtedly the greatest.

One of the reasons why he asked Hawkeye to take him into the port of the Advance City this time was because he needed Hawkeye to lead the way. Although he has now left the windless zone, the sea of this pirate world is so vast. If there is no one to lead the way, even if he gets the corresponding map, it will be difficult to reach the Advance City before the outbreak of the war on the top. As for the second reason, it was that Ling Chen needed the identity of the Eagle Eye Seven Martial Seas, and now that the top war was about to break out, the World Government's guard over the Advance City must have been unprecedentedly strict. Ling Chen needs to use the big man Hawkeye to attract all the eyes along the way to him, so that he can avoid all eyes in the sea and sneak into the city.

……

As Ling Chen had expected, when Hawkeye informed the Navy Headquarters of his request to advance into the city, all the top government officials were shocked, after all, in the current situation, any small loophole could bring unknown dangers. Hawkeye is going to advance to the city to meet Potkas.D. Ace, and this is not a small hole, but a major danger that can affect the outcome of the battle once an unknown event occurs.

But Hawkeye's reasoning to the top of the government was, "If you want me to win the war for you, at least let me see what the man who caused this war is, and if you don't agree to that, then I refuse to participate in this fight." ”

Although he was threatened by Hawkeye like this, the top of the world government had a strong burst of anger, but this king's Seven Martial Seas is an important combat force, especially the "Hawkeye" Mihawk, who is known as the world's first swordsman, is the best of the Seven Martial Seas, compared to the admirals, they are not weak at all, if the navy lacks his help, there is no doubt that they will lose more combat power in this war, and if Hawkeye helps the Whitebeard Pirates, then for their navy, it will cause irreparable losses.

Therefore, for these two reasons, even though he was angry at Hawkeye's arrogant attitude, the top level of the world government could only agree to his request, ordering the warships guarding the advancing city to make a way and let Hawkeye's small ships go to the advancing city unhindered.

"Hehe, Mihawk, you're really good, these warships not only make way for you, they don't even dare to approach your boat, it seems that you are a nightmare in the navy!" Ling Chen was also quite surprised that allowing Hawkeye to lead the way could achieve such an effect, at this moment he was leaning over and hiding in Hawkeye's small boat, and at the same time using his domineering aura to reconnoiter the situation in the surrounding sea at any time.

"It's only temporary, and when we arrive at the port of Advance City, there will definitely be a large number of elites from the navy and even the world government searching for my ship, what are you going to do when the time comes." Hawkeye looked at Ling Chen, who was lying on his boat, and was also a little curious, it was no problem for him to take him to the port of Advance City like this, but once he entered, how could he sneak into Advance City from the port with iron walls and iron defenses?

"You'll find it in a minute, don't be scared then!" Ling Chen pretended to be mysterious and said...... (To be continued......)
