In the ring space, all the porcelain vases were well preserved, as well as a few spirit grasses, some gold, a few books, and even a few clothes and a square jade box.

Yan Duan took out a few porcelain bottles from the ring space and checked them one by one, and found that one of them had as many as five Runmai Pills, plus the two Runmai Pills given by Chu Xiao when he said goodbye to Chu Xiao and Cheng Yiqing before, Yan Duan now has a total of seven Runmai Pills on his body. The rest of the bottles were either empty, or they were elixirs of little value.

A few spirit grasses were just herbs for refining the Runmai Pill, and there was nothing special about it. However, the identification and cultivation of medicinal herbs, as well as the refining of pills, are introduced in several books, which is a rare thing for Yanduan.

For gold, Yan Duan doesn't have much interest, but it may be useful to keep it for the future, and now that he has a space ring, it is more convenient to store things. Now, in addition to the two snake dragon fruits on his body, there is also a raw Xuan Spirit Fruit, as well as a few bottles of pills, and some necessary things. Although there are not many things, it is indeed a little inconvenient to bring them.

Then, Yan Duan took out the square jade box from the ring space. The box is slightly cyan and has sandalwood trim at the edges and corners, which exudes a sense of luxury. Yan Duan opened the jade box and was instantly stunned, what was contained inside was a spiritual heart, the surface was crystal clear, but the inside was blood red.

"Another piece of heart!" Yan Duan muttered to himself.

What exactly is this spiritual heart? How many are there? This piece is smaller than the previous one, what is the matter? Some questions instantly appeared in Yan Duan's mind.

Yan Duan took it out of the jade box and put it in the palm of his hand, and the meridians of his body instantly began to circulate. "Could this spiritual heart have something to do with the Bird Feather Sword Sutra that I cultivated?" Yan Duan looked at the spiritual heart in the palm of his hand, and asked in his heart.

It seems that the answer can only be found by looking for other spiritual hearts. Yan Duan, who was stunned for a while, came back to his senses and said to himself.

Yan Duan took it out of his arms, and put another piece of treasured spiritual heart into the jade box with the current one, and then put it back into the space ring. Then he took out the snake dragon fruit and the Shengsheng Xuanling fruit from his arms, as well as some pills and daily necessities on his body, and put them into the space ring, and then put the ring on his hand. As for the finch knife on his back and the stainless steel dagger in his arms, Yan Duan did not put it in it. Because only in this way can you have a sense of security in such a world where martial arts are respected, after all, this is your own weapon on the battlefield.

After doing everything, Yan Duan returned to the cave and spread a layer of hay in the cave, after all, he might have to live here for a while in the future, if there were no merchant ships passing by here.

Before dark, Yan Duan picked up some fish and shellfish left over from the tide on the beach, then processed them, returned to the cave, and roasted them. Although there is no seasoning, and it is not as delicious as the fish I used to eat in the valley, it is more satisfying, and I am very satisfied with the result.

After a full meal, Yan Duan finally fell asleep early. Fighting sea beasts and five-clawed wolf pythons in the middle of the day made him a little exhausted. It's just that he had a long dream in which he went to a place with thousands of worlds, where another battle began.

When I woke up, it was already dark. Yan got up, got out of the hole, came to the beach, faced the endless sea, and began his morning exercise. The Bird Feather Knife used the fifth potential unintentionally before, but the meridians were almost damaged, and now that he has a spiritual heart, he is very confident in the first ten potentials of the Bird Feather Knife.

After a morning of practice, Yan Duan slowly gained a new understanding of the fifth potential of the Bird Feather Sword Sutra, but he also began to be hungry. So I went into the sea and started fishing, and after catching the fish, I roasted it and ate it, although it was still tasteless, but fortunately it was able to replenish the nutrients needed by the body, and fortunately there was fresh water stored on the island, otherwise drinking water would be a troublesome thing.

After that, in addition to fishing, every day he used his spiritual heart to practice the Bird Feather Knife and the golden fist technique he had previously searched from Qiao Lanhai's body, and read the herbal scriptures and alchemy scriptures that he had obtained from the space ring before in the interval of rest.

Time passed, about half a month later, when Yan Duan looked at the meridians inside, he found that a layer of white membranous things slowly appeared outside his meridians, although Yan Duan was a little worried in his heart, but later found that it not only did not damage the meridians, but accelerated the circulation of the meridians, and also formed a layer of protection for the meridians, and then he was not worried, but he began to pay attention after every cultivation.

During this period of time, Yan Duan slowly had a new understanding of the boxing techniques of the gold system, and when the purple qi came from the east, a faint layer of gold began to slowly emerge on the palms of his hands, and he punched the trees, and the trees broke off in response, and the place where they were hit instantly turned into powder.

On this day, when Yan Duan went to the sea to fish, the bottom of the sea suddenly surged, and the entire sea surface kept shaking. Yan Duan instantly swam out of the water from the bottom of the sea, and saw dozens of currents rushing from a distance. Before Yan Duan could go ashore, dozens of sea beasts instantly arrived at Yan Duan's side, and then attacked towards Yan Duan.

The moment Yan Duan approached, he suddenly avoided it like a swimming fish, but more and more sea beasts began to attack Yan Duan. Words cannot be borrowed in the sea, and the sea beasts are the overlords of the sea, their domain. The crazy attack made Yan Duan writhe and avoid, although it was avoidable, but it made Yan Duan inexplicably feel like he wanted to catch something.

It was only for a moment, but it was the first time in my life that I wanted to catch it. Slowly, Yan Duan avoided the sea beasts with their mouths wide open and their fierce fangs more and more easily. If you look at it from above, Yan Duan at this time seems to be like a fish, constantly shuttling among various sea beasts.

Finally, with this body technique, Yan Duan slowly came to the shallow sea area, stepped on the bottom of the sea, and in an instant, a faint gold appeared on his hand, and then he punched at an attacking sea beast.

A huge sea beast, with its fierce mouth open, rose high from the sea, then let out a terrible cry, and then landed heavily on the island.

More and more sea beasts continued to attack, and Yan Duan kept punching the sea beasts from the bottom of the sea into the air man, and then fell on the island. At the end of the incense, there were already many injured sea beasts on the edge of the island desperately struggling to get back into the sea, but before they could enter the sea, they were bombarded with another punch, and then fell farther away on the island with blood.

Unexpectedly, in just twenty days, Yan Duan connected the gold system boxing method to the eighth grade, and this speed is simply incredible in Dayi. Duan knew in his heart that all of this should be due to the two pieces of spiritual heart and the white membrane that came out of the meridians.

Slowly, the sea beasts in the sea continued to decrease, and even saw that some sea beasts had disappeared. Only then did Yan Duan go ashore and return to the island to look into the distance.
