In the Dayu Empire, those precious cultivation cheats, except for the original version, are like medicines, called cheats potions, as long as the cheats potions are eaten, the information contained in the potions can naturally be engraved in the memory of the brain, which is very convenient, these content things do not need to be memorized by a person, and the specific perception and cultivation depends on each person.

In addition to the fact that the content of the cheats can be engraved into the memory of the human brain, the cheats potion also has a very special effect, that is, "anti-piracy", if the person who drinks the cheats medicine deliberately leaks the content of the cheats to others in any way, the drink will be backfired, and he will become an idiot at best, and he will not remember anything, and he will die directly.

These things, the senior in the Ten Thousand Tribulation Orb had already told Wang Wuyun.

Some secret elixirs that do not have a counter-phagogy effect are called book potions, and the knowledge and information in those books can be freely disseminated, and as long as you drink the potions, you can naturally grasp them.

In the Dayu Empire, a young man with a mature brain after the age of eighteen, as long as he drinks a few book potions, he may be able to master more knowledge than the most knowledgeable and professional scientists on the planet, of course, the price of these potions is by no means cheap, not only not cheap, but also very expensive, even the most ordinary book potions, and N times more expensive than the same ordinary book.

Wang Wuyun picked up the bottle of the secret elixir of "Star Chasing and Moon Dancing Sky Technique" and looked at it curiously for a long time, and finally put the bottle back into the box. He wants this thing, just to hide people's eyes, he won't drink it, if he really drinks it, he is really stupid, he now has the "Star Chasing Moon Dance Sky Technique", even if he teaches it to others, he doesn't have to worry about any backlash, it's hard to say if he drinks it.

The third box opened, and inside was some prepared pills, there were many types, mainly some things for healing, as well as pills for cultivation in the Double Heaven Realm and some pills with special purposes, which were very well prepared.

The fourth box looks the biggest, but also the most valuable, the box is more than two feet long, more than one foot high, it looks black, but the box is covered with quaint silver patterns, it looks very unusual, Wang Wuyun saw three small seal-like golden characters in those patterns - Shenbing Building.

Looking at the size of the box, Wang Wuyun felt that it should not be a sword inside, because the sword was longer, but he couldn't hold it for sure, and maybe there were strange swords and weapons inside.

Just when Wang Wuyun was thinking about how to open the box, Jing Qingyang opened his mouth, "You can't open this box, I'll ...... it", as he spoke, Jing Qingyang had already stretched out his hand, put his palm on the surface of the box, and didn't see him do anything, the box emitted a light, swept Jing Qingyang's palm, and when Jing Qingyang retracted his hand, the box automatically opened, revealing the contents inside.

Seeing the contents of the box, Wang Wuyun was stunned, the box contained a silver metal ball larger than a basketball, I don't know what it was for. The only thing that makes people feel amazing is that the metal ball floats in the middle of the box, as if it doesn't have the slightest weight.

"Elder Jing, what's the use of this ball?" Wang Wuyun asked Jing Qingyang.

"This is the sword you want!"

Hearing Jing Qingyang say this, Wang Wuyun looked at the metal ball, and then at Jing Qingyang, and the expression on his face was just one sentence - I don't read much, don't lie to me......

"This sword is different from the swords you usually use, this sword is called Thousand Illusions, it is cast by the sword-casting master of the Dayu Empire's Divine Soldier Building using super wisdom metal and star core gold, you put your hand on it, don't move, you will know if this thing is a weapon......"

Hearing Jing Qingyang say this, Wang Wuyun also put his palm on the suspended round metal ball.

The suspended metal ball was cold in his hand, and the feeling at the beginning was similar to touching the metal ball as touching a steel ball of the same size, but after just over ten seconds, Wang Wuyun felt that the metal ball began to change, and the temperature of the ball he touched began to grow a little bit taller, becoming warmer.

"Now you feel that the temperature of the sphere is rising, don't be surprised, don't leave the sphere with your hands, keep in touch, this is the process of activating the Thousand Illusion Sword......" Jing Qingyang reminded beside him.

At this moment, Wang Wuyun's heart was completely occupied by curiosity, he had seen Lei Mengmeng's silver needle, and the silver needle was also a smart metal, so he also wanted to see how this metal ball could become a weapon.

Suddenly, Wang Wuyun felt his fingers pass, and the originally smooth surface of the metal ball suddenly grew something like a needle tip, piercing his finger.

A drop of blood dripped from Wang Wuyun's finger and fell on the surface of the metal ball, which was instantly absorbed.

Then the original silver metal ball began to change color, and slowly the whole metal ball turned red, like blood, and then the red metal ball changed back to silver, and the surface of the originally solid metal ball suddenly became soft, and Wang Wuyun's palm, who was touching the metal ball, suddenly grabbed the metal ball, and then the metal ball began to flow along Wang Wuyun's palm and arm towards his body like growing vines and mercury......

Wang Wuyun's eyes widened, watching this strange process and the change of the metal ball, as the metal liquefied and turned into mercury flowing towards his body, the feeling on Wang Wuyun's skin was like soaking in warm water at thirty-nine degrees, and he didn't feel uncomfortable at all, nor did he feel the weight of those flowing metals.

The flowing metal and extended vines flowed directly down Wang Wuyun's arm to his body, and Wang Wuyun felt the metal liquid crawl onto his shoulders on both sides, and then covered his chest and back against the skin, wrapping his body around him, as if it had become a close-fitting armor.

Wang Wuyun directly untied his clothes in front of Jing Qingyang, and looked at his chest and lower abdomen curiously, the mercury-like metal wrapped the torso of his upper body, his shoulders, chest, back, spine, lower waist, and lower abdomen were all wrapped, shining with silver, making Wang Wuyun's body look like it was carved from metal.

But in just a few seconds, those metals began to become transparent, and then slowly turned into the same color as Wang Wuyun's skin, and then, those metals were completely invisible, and directly became the skin of Wang Wuyun's upper body, compared with before, at first glance, only the muscles on Wang Wuyun's torso became more obvious, more lined, eight-pack abdominal muscles on the lower abdomen, the pectoral muscles were angular and obvious, the back muscles were broad and thick, and the muscles of the shoulders were more prominent, especially the latissimus dorsi, teres major, and deltoid muscles became obvious......

Wang Wuyun knew that those extra muscles were of course not the muscles of his body, but the flowing metal that covered his body just now.

Although the metal ball had been completely possessed by Wang Wuyun's body, Wang Wuyun did not feel the slightest discomfort on his body, and if he didn't feel it carefully, he couldn't even feel any changes in his body, it felt like wearing a comfortable and light T-shirt, he felt almost nothing, and it didn't affect his movement at all.

"Elder Jing, this is ...... Weapon ......" Wang Wuyun was stunned for a long time.

"This is the first form of the Thousand Illusion Sword, and it is also a non-combat form - close armor, in this state, the Thousand Illusion Sword will become your personal armor, which is equivalent to wearing an invisible armor on you, and there is nothing abnormal on the outside!"

"And how do you fight with it?"

"You just have to imagine what kind of weapon you need in your hands......"

"Just think about it?"

"Well, think about it, the Thousand Illusion Sword will turn into any cold weapon you need!"

Wang Wuyun tried to imagine an ordinary long sword......

In less than two seconds, Wang Wuyun felt as if warm water was flowing on the skin on his body, and the warm water gathered into his arm, and in the blink of an eye, a snowy double-edged long sword appeared in his hand, and the appearance of the long sword was exactly the same as Wang Wuyun imagined.

Such a weapon, like a mythical story, is really beyond Wang Wuyun's imagination......
