Lu An returned to the bamboo chair while gnawing on the steamed bun, sat on it and gnawing on it. He began to think about it again, always feeling a little empty now, and now he doesn't need to consider his injuries.

What we should consider is how to improve one's strength, or how to fill in the pits that fall from the second to fourth grades, it is best to make a significant progress in your realm, otherwise I would really be sorry for the sword on your back.

But the idea is good, but the result is a bit unsatisfactory.

For three days, Lu An locked himself in the room without leaving the house, holding a sword, holding a sword, holding a sword, raising a sword, swinging a sword...

After wiping the sweat on his head, Lu An suddenly smiled, feeling that his behavior was a bit ridiculous. It was too whimsical to want to become a fat man in one bite.

noon.

Lu An took out all the things related to the sword on his body and placed them on the ground. Cold Blood, Meteorite Iron Sword, Sword Theory, the incongruous thing that Xia Luo gave, the size of a palm, like a mirror, and finally even the old sword hilt was taken out.

Lu An sat on the bamboo chair, supporting his head, shaking his legs, and dazed.

Gu Yan shook out from somewhere again. Looking at the pile of things on the ground, he couldn't help but ask: "Master Lu, are you burning things with the sun?" After that, he looked at the sun.

Lu An nodded.

Seeing that Lu An didn't want to pay much attention to him, Gu Yan squatted down on his own and began to observe the things on the ground. He also muttered to himself: "Cold blood, the best sword. Meteorite sword, Earth martial arts, Sword Taoism, Sword Taoism, Kunlong mirror, magic weapon. Hey, the sword hilt?"

"Kunlong Realm? Do you know what this mirror is?" Lu An suddenly spoke.

Gu Yan replied: "Yes, this Kunlong mirror is still very famous. It is said to be forged with Kunlong scales. It is smooth and shiny, energetic, and looks like a mirror. Therefore, it is called Kunlong mirror and is easy to recognize."

"Kunlong?" Lu An asked in confusion.

"A saying in Yin and Yang, Qiankun, Ganlong is Yang, Kunlong is Yin, one Yin and one Yang are all empty. Anyway, no one has seen it before, it is just a saying." Gu Yan explained.

"Then what's the use of this Kunlong mirror? This is given to me by someone else. I don't know how to use it." Lu An said.

"The Kunlong Mirror can be regarded as a relatively rare magic weapon, and its function is to defend itself, in other words, it is to spend money to save lives." Gu Yan said with a wicked smile.

When Lu An heard this, he looked at Gu Yan's smirk and felt something was wrong, "Do you want to spend money?"

Gu Yan nodded, "Looking at the level of this Kunlong Mirror, it should be considered a pretty good magic weapon. If nothing unexpected happens, you should be able to block the attack below the Grandmaster. As long as the power of this attack is not at the Grandmaster level, you can block it and ensure that you are not dead, but it will cost a lot of money."

After hearing what Gu Yan said, Lu An was immediately happy, "Are you sure? All the following masters can do?"

Gu Yan nodded, "I'm sure there is one in Jiangcheng, which is too rare and the cost is too high, so it can't be used, otherwise the four of us will definitely have one."

"It's too expensive? How expensive?" Lu An had a bad premonition.

"Use ten spirit crystal essences once." Gu Yan said with a smile.

When Lu An heard this, he immediately took a breath of air conditioning, and then his expression that was still happy just now became muscular.

Looking at Lu An's expression, Gu Yan was a little happy and continued, "Master Lu, don't be so discouraged? Ten spirits exchange for a life. Many people are willing to do things, but they just don't have the financial resources. But there is a good news that this Kunlong Mirror can be used once, and someone has already raised the bet."

Lu An looked at the Kunlong Mirror in surprise and joy, and murmured: "Ten Spirit Crystals, that's a whole of ten thousand Spirit Crystals. Xia Luo really invested a lot of money."

Gu Yan then said, "This thing is very simple to use, just refine it."

Lu An didn't say anything, and directly picked up the Kunlong mirror and refined it. After a while, a transparent sequin was added to his arm, which was very thin and attached to his arm and would not interfere with the movement of his arm at all. It seemed that he could easily control the sequin with his mind.

Gu Yan then continued: "After refining, it will attach itself to the body and cannot be used outside the body. However, the Kunlong Mirror can move on the body surface at will to help you withstand fatal injuries. Generally speaking, it is placed on the back or chest. One is your own key, and the other is your own blind spot."

After hearing this, Lu An nodded.

Gu Yan glanced at Lu An and continued, "But this thing is not omnipotent. Master Lu, you should feel that this Kunlong mirror is a dead object and needs to be controlled by mind and mind to move. So if the opponent's speed is fast enough, then the mind is not enough to control it. If the Kunlong mirror does not have time to move, there will be no way to help you resist that attack. Therefore, it is a very secret thing to have the Kunlong mirror in your body. You must never let anyone know where the Kunlong mirror is attached."

Lu An nodded again. That's true. If someone knows where the Kunlong Mirror is and deliberately stabs the Kunlong Mirror in a place that the Kunlong Mirror cannot reach when he kills you, then this second life will be wasted.

"The Kunlong Mirror, the size of a palm, is already considered a rare group. All of them have such good defense and can withstand a blow below the Grandmaster. Ordinary ones may only be the size of two or three fingers, and the effect will be much worse. The best Kunlong Mirror can only resist a grandmaster-level attack once, but that kind of magic weapon is the rarest, and it is even rarer than the catastrophe pill." Gu Yan sighed and looked at Lu An with envy.

After listening carefully to everything Gu Yan said, Lu An smiled on his face, just like the rising sun, the first good news in a few days.

Seeing Gu Yan's melancholy aside, Lu An pointed to the hilt of the sword on the ground and asked, "What about this thing? Do you know what it is?"

Gu Yan looked at the hilt of the sword and immediately fell into deep thought.

Lu An looked at Gu Yan pondering, motionless, very curious, there was a chance, it seemed that he might know it. Then he asked, "Have you seen it?"

Gu Yan frowned, opened his mouth to speak, but stopped, tapped the folding fan, and said in a sequel: "It seems that it was described in an article, but I can't remember it clearly. I don't know if it is this, I have to think about it."

Lu An immediately raised his spirits again, sat upright, urging Gu Yan to think quickly.

Gu Yan hugged his chest and began to pace back and forth, knocking on the fan from time to time, touching his head, his brows kept frowning.

Just like that, for half an hour, Lu An stared at Gu Yan, and Gu Yan left for half an hour.

Finally, Gu Yan slapped the folding fan, relaxed his eyebrows, and said happily: "I understand, this thing is called the Shadowless Sword."

After hearing this name, Lu An suddenly felt a little unreliable and repeated it, "Shadowless Sword?"

Gu Yan nodded affirmatively, and then said, "It must have been 5 years ago. At that time, Master Bai asked me to read books every day, so he threw me into the library. There were tens of thousands of books of various types, and he told me that he would not have to come out if he could not finish reading it."

Lu An interrupted directly: "Tell me the point."

Gu Yan said oh twice, "I remember a book called "Residual Soldiers". It looks very old and worn. The whole book is made of sheepskin and has been refined with special techniques. But even so, it was already broken when I touched it. It all talked about some magical weapons and weapons, but for some reason, they were eventually damaged. However, this kind of broken remaining weapons are still the most powerful weapons in the world. The hilt of the sword once appeared in this book, although I don't know if it is the hilt of the sword mentioned in the book."

After hearing this, Lu An silently picked up the hilt of the sword. When he held his hand tightly, he felt a very comfortable feeling, but there was no other reaction. He tried the internal force to activate it, but there seemed to be no feeling at all. He tried the Ten Thousand Swords Art again, but he couldn't even condense the sword energy.

Lu An tried all the sets, but nothing happened. He couldn't help but frown and glanced at Gu Yan, and then continued to ask, "Is there anything else in that book?"

Gu Yan bit his finger and said, "It's been too long, and the book is too old, and some words can't be seen clearly. I only remember a few words. Jian Wuying held it with one hand, and the sword broke through the sky without thinking. Later, it was damaged, and the sword energy traverseed tens of thousands of miles. There were a few words after that, but it was already very vague."

Lu An nodded, looking at the broken sword hilt in his hand, the shadowless sword? The sword breaks through the sky? The sword energy is ubiquitous? It seems that if it is true, the sword hilt should be a treasure, and it may have been the most powerful magic weapon in the world. Unfortunately, it has been broken now, so I weighed it casually, "Although I don't know whether it is true or false, it is very comfortable to hold the sword hilt. You can use it as a sword in the fourth realm of the sword. It saves you from swinging the sword every day, which is indecent."

After hearing this, Gu Yan laughed immediately, "Master Lu, your thinking really makes me feel inferior to myself, Gao."

Lu An smiled and replied, "It seems that Master has asked you to read so many books. Is it really useful? Although your way of speaking and doing things is a bit old-fashioned, there are still a lot of things in your mind. Thank you."

After hearing this, Gu Yan immediately became serious again, folded his fists and bowed to his disciples' salute, "Master Lu, you are joking."

Lu An glanced at Gu Yan who was solemn, and whispered: "I can't save you, pretend I didn't say anything."

Gu Yan laughed and then said, "The teacher's order has something to do and not do, but I think it's better to respect Lu as his teacher."

Lu An has never understood Gu Yan's thinking or the order of his master, "Where is it worthy of your respect for me as your teacher?"

Gu Yan shook his head and replied, "I don't understand Master Bai's orders very much, but after spending so many days together, I saw Master Lu almost died for us. This is worth learning from. As the saying goes, death can be lighter than a feather, or more than Mount Tai. If Master Lu died in the forest to save us this time, it would be really lighter than a feather."

Lu An was a little confused when he heard this, "How come you feel like there is something in the words?"

Gu Yan replied: "The love is sincere and there is no falsehood."
