These humanoid monsters hiding on the beach, with not much flesh and blood left on their bodies, looked like they should be undead creatures, but Li Nan didn't even feel the slightest cold and dead aura on their bodies.

The undead creatures approached Angelica and the others, and when they were close enough, Li Nan saw that they seemed to have a dark gray metallic coating on their bodies.

An extraordinarily powerful monster, presumably the leader level of the undead creatures, stood in front of Angelica and pointed it at her with its black hole sockets, as if to verify her identity in some way.

After a moment, the undead leader nodded in satisfaction, bent down slightly and performed a noble etiquette at Angelica, and then raised his right arm to point to the center of the island, signaling everyone to follow it.

Li Nanyi was bold, and Angelica was there, so he was not afraid, but remained vigilant and followed the footsteps of the undead creatures and walked forward.

As he continued to walk, Li Nan finally recognized the layer of silver-gray metal on the bodies of these undead creatures.

Lead is a weak metal, soft and malleable, toxic, and also a heavy metal.

Lead was originally bluish-white in color, and the surface of the air was quickly covered with a layer of dull gray oxide. It can be used in many fields such as construction, metallurgy and military. It can also be used as sulfuric acid corrosion resistance, ionizing radiation resistance and so on.

The surface of lead can be used to form an alkaline lead carbonate film in the air to prevent the inside from being re-oxidized, and lead bricks or lead coats can be used to protect against X-rays and other radiation.

It should be because the undead creatures are covered with a layer of lead, so Li Nan can't feel the other party's dead air. From this point of view, in addition to being a brutal pirate, Howard Blackbeard was also a very innovative inventor.

The island was full of trees, weeds, and vines, and Li Nan and Angelica followed the undead creatures for more than forty minutes before they came to a low rocky mountain.

The undead creature pushed aside the dense green vines on the stone mountain, revealing a hidden hole, and after entering the cave and walking forward for a few minutes, Li Nan's eyes suddenly lit up, and a tall and spacious stone chamber appeared in front of him.

If there is no one to lead, unless a large number of people are mobilized, no one would have imagined that there is such a hidden stone chamber hidden under the low stone mountain of this desert island.

When Angelica saw the old man sitting on the large wooden chair in the stone room, her eyes immediately turned red and she ran over quickly.

Li Nan also walked forward slowly, his eyes fixed on this legendary figure, and carefully observed him.

Since the other party's nickname is Blackbeard, it is not surprising that he has a thick and very distinctive beard, and his beard is too flamboyant, and he is tied into many slender braids with straps.

Although Blackbeard sat on the chair, Li Nan could tell from his broad shoulders that when he stood up, he must be very tall and strong.

"Father, I'm back!" Angelica crouched down and hugged Blackbeard's legs and cried excitedly.

Blackbeard glanced at Li Nan, who was standing not far away, reached out and stroked his daughter's long wavy hair, and said softly, "Anji, it's good that you can be safe." ”

The father and daughter gently talked about other things, and Li Nan, who had nothing to do, did not disturb them, but focused on the decoration of the stone room.

An old captain's suit hung from the damp rock wall, flanked by a leather ammunition pouch and six delicate short-handled firearms, as well as a sheathed longsword with gems studded with gems, much larger than a normal Western sword, presumably Blackbeard's personal equipment.

Similar to Captain Morgan's room of the Shadow Lord, most of this stone chamber is also occupied by stone and wooden tables, and all kinds of crucible utensils and materials needed for alchemy are piled up everywhere.

The most conspicuous thing in the room is a dark red rectangular stone table, you don't need to walk over, Li Nan stood in the distance and smelled the strong smell of blood emanating from it, plus the set of knives on the stone table and the human organs placed in the glass bottle nearby, this should be a dissecting table.

Alchemist is a comprehensive profession in this era, somewhat like a Taoist priest in the East.

To be a qualified alchemist, you must have knowledge of medicine, pharmacy, chemistry, etc., as well as innovative ideas and indomitable determination.

Blackbeard is certainly not the only one who combines alchemist and black magic, but there are not many people who can reach his height.

Although Blackbeard didn't stand up and was covered with a thick blanket, Li Nan could see his thick neck, which had a very conspicuous scar on it.

Originally, Li Nan was still a little skeptical about the legend of Blackbeard, after all, he could still live after his head was cut off, this kind of thing usually appears in myths and legends, but after seeing the scar formed by the sharp axe on the other party's neck, he really believed it.

The two talked for a while, Angelica wiped the tears on her face, got up and waved at Li Nan.

"Father, this is what I told you about Li Nan, although he is the Pirate King and the Pirate Emperor, he is different from those who have harmed you......"

"Huh." Blackbeard patted Angelica's hand lightly and said to her with a smile, "Don't be nervous, I won't do anything to your little lover." ”

After comforting his daughter, Blackbeard looked at Li Nan with electric eyes and asked, "Anji said that you have an elixir that can restore my health?" ”

"Yes!" Li Nan didn't talk nonsense, and directly took out a bottle of Shadow Gold from the storage space and handed it over.

Blackbeard is a master of alchemy and dark magic for many years, and after he took the Shadow Gold, opened it, looked at it briefly, and smelled it, he already knew the origin and approximate effect of this object.

"My injuries are too severe, I've barely survived all these years, and I need all this potion in your hands."

"Haha......" Li Nan said slightly apologetically: "I have a very close relationship with Angelica, for her sake, I can give you a bottle for free." But if you need more, you'll need to exchange it. ”

Blackbeard nodded, "Reasonable, what do you want?" ”

Li Nan pointed to the sheathed long sword hanging from the wall and said with a smile, "I want the sword of Tritong and the ghost lock on your ship. ”

It seems that this condition makes Blackbeard feel very painful, as he frowns and thinks about it for a long time.

"Father, your body is important, and those things are outside your body."

Angelica's words reached Blackbeard's heart, and after hesitating for a moment, Blackbeard looked at Li Nan and said solemnly, "Okay! I promise this deal! ”

Hearing Blackbeard's words, a big stone in Li Nan's heart fell to the ground, the ghost rigging on Blackbeard's flagship 'Queen Anne Avengers' should belong to the S-class ship parts, and if the 'Sea King' is installed with this part, its main mission will not be far from being completed.
