After Li Yichen returned to the room, he lit the lamp in the room, closed the door, took out an alchemy furnace for alchemy from under the bed and put it on the table, and put the crystal nucleus of a third-level fire demonic beast on top of the alchemy furnace. The alchemy furnace is also a kind of alchemy product, and it looks a little similar to the forging furnace used for forging, but the forging furnace uses ordinary fuel to generate heat and melt the metal that needs to be forged. The alchemy furnace is to engrave the formation on the furnace body through alchemy, and when using it, it is necessary to put the crystal nucleus of fire energy on the furnace at the array eye, and the fire energy is excited through the formation to produce high temperature.

Since alchemy often melts some rare metals, and these metals have very high melting points, the temperature that alchemy furnaces can produce is very high. For example, since Li Yichen's alchemy furnace is only a small alchemy furnace, it can only be simply engraved with a first-level fire energy excitation formation, but the temperature that this alchemy furnace can reach to stimulate the third-level demonic beast crystal nucleus is about ten times that of an ordinary forging furnace.

Put the Warcraft crystal nucleus on the alchemy furnace, and immediately the energy of this crystal nucleus was activated by the formation, only to see that a pile of fiery red flames was produced in the furnace, as the crystal nucleus energy was stimulated, the color of the flames not only did not deepen, but became lighter and lighter.

When the color of the flame slowly changed from red to light blue, Li Yichen took out the small black card from his arms and put it in the alchemy furnace.

After the black card was put into the furnace, Li Yichen's eyes stared at the brand motionlessly, and after a tea time passed, the black card was still lying quietly in the furnace without any reaction.

Seeing that there was no reaction from this brand in the flames, Li Yichen thought for a moment and removed the third-level crystal nucleus. Open the drawer on the table and take out a fourth-level salamander's crystal nucleus from the innermost part of the drawer, this is Li Yichen's only fourth-level crystal nucleus, and it is also the limit of the crystal nucleus that this alchemy furnace can excite. After these fourth-level crystal nuclei were put up, the color of the fire in the alchemy furnace became even lighter, slowly turning from blue to light blue, and the temperature in the furnace was at least twice as high as just now. At such temperatures, even Mithril will begin to melt.

Li Yichen stared at the furnace tightly, a quarter of an hour passed, two quarters of an hour passed, and the black card still did not react at all in the furnace. The whole brand has not changed its color at all, it is still black and black. Perhaps the dirt stained on the outside has been vaporized by the high temperature, and the color of the current black card is even darker and more quaint.

Seeing that at such a high temperature, such a long time had passed, and there was no sign of melting of this brand, Li Yichen wanted to take down the crystal nucleus first to see if he could measure the effect of this brand in other ways. Suddenly, Li Yichen's eyes lit up, and he felt that the temperature around the black card in the furnace seemed to be lower than the temperature in other places.

Afraid that he was staring at this brand for too long and his eyes were dazzled, Li Yichen rubbed his eyes vigorously, and then saw that this black card seemed to be able to absorb the surrounding heat and absorb all the fire around it. Since the color of the flame in the alchemy furnace is relatively light now, if you don't look at it deliberately, you really can't see it at once.

In order to verify the guess in his heart, Li Yichen took out a small piece of refined iron and put it on the brand. Generally, the melting temperature of refined iron is very low, and in the alchemy furnace, even if the third-level crystal nucleus is used, it will melt instantly, and if the fourth-level crystal nucleus is used, it may be vaporized instantly as soon as it is put into the alchemy furnace.

As the refined iron was put into the furnace, Li Yichen opened his eyes and stared at the piece of fine iron, sure enough, the brand should be able to absorb the surrounding flames, and the fine iron fell on the brand, but there was no instant melting, and the fine iron lay there quietly, as if the alchemy furnace had not activated the crystal nucleus at all.

couldn't hold back the surprise in his heart, Li Yichen knew that he should indeed have bought a treasure this time. I don't know what other effects there are, but at least it should be able to absorb fire.

Li Yichen picked up the kettle on the table, poured himself a glass of water, and took a deep breath after drinking it, stabilizing his excited mood.

When his mood calmed down, Li Yichen took the crystal nucleus from the alchemy furnace, and when the temperature in the furnace dropped slightly, he used a slender stick to remove the fine iron from the black card and dial it next to the black card. After dialing the fine iron, Li Yichen put the crystal nucleus back into the alchemy furnace, and as soon as the formation was activated, he saw that the piece of fine iron in the furnace disappeared in an instant, completely vaporized by the high temperature.

Seeing this situation, Li Yichen was already fully sure that this black card could be extinguished. After removing the formation, Li Yichen couldn't wait to pour the black card to the ground.

After pouring out the black card, Li Yichen squatted on the ground and touched the black card with his fingers, and there was no imaginary hot feeling on his fingers, but a smooth touch came from his fingertips. Li Yichen picked up the black card with his hand and put it in front of his eyes to examine it carefully. Coming out of the alchemy furnace, there was no obvious change in this black card, because the dust on it had fallen off, it looked even darker and more quaint.

Originally, I was thinking about whether the acid secreted by the acid ant beast would have a corrosive effect on this black card, but seeing that the fire fighting effect of this black card was so good, Li Yichen didn't dare to make other attempts, in case he damaged this black card, he would really want to cry without tears.

After discovering the fire-repelling function of the black card, Li Yichen was even more curious, but he was afraid that it would damage the black card. After holding this black card in his hand and playing for a long time, Li Yichen took out a copy of "Appreciation of Treasures of the Divine Dragon Empire" from the bookshelf and put it on the table. "Appreciation of Treasures of the Shenlong Empire" was edited by the official organization of the Shenlong Empire, and it summarized all the divine weapons, heaven and earth spiritual objects and other items in the history of the entire Shenlong Empire. Holding the black card in his right hand, he slowly flipped through the book "Appreciation of Treasures of the Dragon Empire" in his left hand. Line by line, word by word, he looked at it carefully, and as long as he saw that the description was slightly similar, Li Yichen approached the black card in front of the book and carefully checked it.

One page was turned over, two pages were turned over, and until the last page was turned, Li Yichen did not find anything similar to this black card.

After Li Yichen closed the book "Appreciation of Treasures of the Divine Dragon Empire", he sighed lightly. It seems that this black card has not appeared in the history of the Shenlong Empire, and if you want to know what it is, you have to think of other ways.

looked at the leaky pot in the room, it was already the third watch, Li Yichen couldn't think of what this black card was for a while, so he had to go to the academy after dawn to check the information to see if he could know what it was.

Since he was going to take this black card to the academy, Li Yichen put the black card in the pocket of his underwear on his chest. After taking off his coat and washing up, Li Yichen lay on the bed and prepared to rest.

Maybe it was because he was thinking about things in his heart, Li Yichen didn't sleep well all night, and he felt confused all night. As soon as Yin Shi arrived, Li Yichen opened his eyes, and after so many years of habit, although he didn't sleep well all night, he still woke up at the end of the day.

As usual, after Li Yichen practiced the Five Elements Boxing, he swam to the rockery in the lake to meditate and run the "Five Elements Foundation". Gently touch the tip of your tongue against the roof of your mouth, and face your heart towards the yuan. After Li Yichen ran the "Five Elements Foundation" mental method, the surrounding vitality suddenly rushed to Li Yichen's chest as if he was desperate, slowly forming a whirlpool.

Li Yichen was running "The Foundation of the Five Elements" slowly, and suddenly he realized that something was wrong. In the past, although the vitality of this heaven and earth would disappear when it reached the dantian, but today, although I felt the fluctuation of the vitality of heaven and earth outside the body, there was no trace of vitality entering the body, and there was no way to repair this tired body at all.

Li Yichen thought for a while, maybe he didn't rest well, so his mental state was not very good, which led to today's cultivation being completely ineffective. Slowly stopped the operation of "Five Elements Foundation" and sat quietly for a while, before Li Yichen slowly opened his eyes.

If Li Yichen had opened his eyes earlier, he would have found that with the cessation of the operation of the "Five Elements Foundation", the already manic Heaven and Earth Yuan Qi slowly became calm.

I sat quietly on the rockery for a while, and waited for my body to recover slowly. Li Yichen jumped into the lake from the rockery, and walked directly to the middle courtyard after going ashore.

Since Li Xinyuan and the others were going to participate in the trial today, they got up early in the morning and went to the academy to report, so Li Yichen walked in the direction of the academy alone after eating breakfast.

Because Li Yichen didn't rest well, and he was still thinking about the black card, he was in a trance all the way. Just when he was about to arrive at the academy, Li Yichen felt a light touch with something, and then he heard:

"Smack"

With a bang, it was as if something had broken.

Then the arm was grabbed, Li Yichen looked up and saw that he was a young man in his twenties, with a braid, thin eyebrows and small eyes, a garlic nose, thin lips, and when he opened his mouth, he saw a mouth full of big yellow teeth, and the brocade robe he was wearing didn't know where he got it, it was one size bigger than his body, and the more he looked at it, the more obscene he became.

"Boy, do you have long eyes when you walk? Uncle is such a big person here, and you hit him too. ”

I saw that the obscene young man's small eyes were looking up obliquely, and he said to Li Yichen with white eyes facing the sky, and no one in his eyes.

"This big brother, I'm really sorry, I was thinking about something just now, I didn't see clearly when I was walking, and I accidentally bumped into you, so I ask your forgiveness, big brother. ”

Li Yichen thought to himself, probably because he accidentally bumped into someone else while walking, so he opened his mouth to apologize.

"Boy, you broke grandpa's things, and you want to leave when you say sorry, and if you know each other, you will lose money to grandpa. ”

The lewd young man pointed to the broken porcelain on the ground and said.

Li Yichen looked at the ground, there were a few broken porcelain pieces lying on the ground, and he immediately understood in his heart that this was touching porcelain. After seeing that the hour was not early, the academy was about to start classes, so he said quietly:

"Big brother, it was really me who was wrong just now, you see I have a tael of silver on me, why don't you take it and drink it, big brother?"

"A tael of silver machine wants to send me away, this is a vase that my grandfather bought for fifty taels of silver in Jubaoxuan. It's best to obediently give fifty taels of silver to grandpa, even if you lose a penny of silver, grandpa will break your legs. ”

Seeing that Li Yichen seemed to be easier to bully, the lewd man said viciously.

Hearing the lewd man open his mouth like this, Li Yichen couldn't help but be angry, he wanted to calm things down, but he didn't expect that the other party would have to make inches, so he said coldly:

"I only have one piece of silver, if you want to take it, don't get in the way of the master. ”

After speaking, Li Yichen pushed the man away.

"Where is there a wild boy who has no one to raise, and I want to send my grandfather and me for a tael of silver, it seems that my grandfather has no choice but to beat you. ”

After the lewd man finished speaking, he swung a punch at Li Yichen.

Parents and family members are Li Yichen's counterscales, as soon as he heard the lewd man insulting his parents, Li Yichen no longer thought about anything to calm down, his body was slightly on one side, dodging the man's fist, and then his left foot retreated half a step, half squatting, a side kick, and his right foot kicked the man fiercely.
