Watching Jin Chen's figure leave the study, in the straight and long corridor, gradually becoming smaller, turning, and disappearing, Wen Ying's eyes sparkled.

"Don't shed tears for other men!" Grand Duke Ivan said angrily. He didn't expect that Wen Ying cared so much about Jin Chen, which made him jealous.

The tears in Wen Ying's eyes were swirling, but she couldn't bear it. Listening to Grand Duke Ivan's words, Wen Ying closed her eyes, and two lines of tears flowed from the corners of her eyes.

Wen Ying didn't know why she was crying. She and Jin Chen have only met three times, the first is in the Dark Island, the second is yesterday in the fire cage of the Plexi Prairie, and the third time they have met for the longest time is today. She didn't know much about Jin Chen, and she wasn't even friends with Jin Chen, but she knew that from the moment Jin Chen's loyal slave spell took effect, or rather, from the moment the two of them met on the Dark Island, Jin Chen's fate was closely linked to her. From now on, Jin Chen was born for her and died for her, which may be the reason why Wen Ying cried.

Grand Duke Ivan couldn't help but bow his head, he kissed away the tears that flowed from the corners of Wen Ying's eyes, only to feel that the tears were hot and had a hint of salty and sweet taste.

Wen Ying didn't want to make Grand Duke Ivan angry, and she didn't want Jin Chen to be sad, so she kept holding back. Originally, Wen Ying didn't like Grand Duke Ivan to be intimate with her in front of her attendants, but now she finally couldn't help licking her cheeks --- Grand Duke Ivan's warm and soft tongue, such an intimate gesture was originally uncontrollable pity, but at this moment it made Wen Ying angry.

"What are you doing? Are you sick? Wen Ying said unhappily.

"The Protoss never gets sick, only other races get sick, and the Terrans are especially prone to get sick." Grand Duke Ivan was stunned, he guessed, this sentence "Are you sick?" Most likely, it is an abusive word on Earth.

Thinking that Wen Ying was actually unhappy with herself, Grand Duke Ivan became angry. But when his divine sense sensed Wen Ying's tearful eyes, Grand Duke Ivan's heart softened, and his anger disappeared, and he said gently: "Don't worry too much, I ordered someone to keep an eye on Jin Chen on Death Island, even if he can't open the magic source cave sky, he won't let him die." ”

To the ears of Count Alaric, Grand Duke Ivan's tone was doting.

"Really?" Wen Ying said pitifully, "Then after sixteen years, you will let Jin Chen come back, okay?" ”

Count Alaric had already stood in front of the black crystal table, he looked at the two in front of him, and thought to himself: "Grand Duke Ivan's favor for Wen Ying is more than he did to Scarlett back then. ”

But Wen Ying's words made Count Alaric wonder: "Why sixteen years? Could it be that Jin Chen's talent could be compared to that of Elder Wuxin? ”

The vast majority of the demon people who have a magic source in their body must ignite the magic power source after the age of ten, and those who ignite the magic power source before the age of ten are considered to be extremely suitable for cultivation and have great cultivation talent.

The demon people who ignited the source of magic power went through the realm of condensation and burning until they opened the realm of the source of magic power, and the length of time varied. But from igniting the magic power source to opening the magic power source cave, the cultivation time of the ten ** is more than three hundred years, and about five hundred years is the most common. In fact, the vast majority of the demon people who ignited the source of magic power, after reaching the burning realm, they could not go any further--- the person who opened the magic source cave could be said to be one in case.

In the eyes of the Protoss, only the demons who have opened the Cave of the Source of Magic Power are the truly useful people. The lifespan of a demon person is generally only a thousand years, and if it takes five hundred years to open the magic power source cave, even if the lifespan can be extended by a few hundred years, it is still too short for a god person who can exist for ten thousand years or even longer. Therefore, how to speed up the speed of igniting the magic source demon people to open the magic source cave has become a problem for the Protoss to consider.

Those demons who were considered extremely talented to ignite the source of magic power before the age of ten would be sent to Death Island, and under the order of the Emperor of the Heavenly Kingdom, a large number of gods and demons and witch spells would be used to boost their cultivation, so that they could open the magic source cave as soon as possible. Even so, it usually takes about a hundred years. For more than 5,000 years, the fastest demon to open the Cave of Magic Power on Death Island was Jin Zheng, who spent seventy-four years at that time.

It is said that the demon clan who has opened the magic source cave heaven the fastest in the X era so far is the Heartless Elder. It only took him twelve years from the age of three to the age of fifteen to open the magic source cave, and it was rumored that Elder Wuxin had excellent luck at that time, plus he was extremely intelligent, and the age of Elder Wuxin at that time was only fifteen years old, which was also a very important reason why Elder Wuxin was able to finally become the chief elder of the Demon Elder Council. The other elders of the current Council of Elders, second only to the Hollow Elder of the Heartless Elder, also took sixty-seven years to open the Magic Source Cave Heaven, but at that time, the Hollow Elder was already more than a hundred years old. As for the Heartless Elder who opened the Magic Source Cave Heaven at the age of fifteen, he was also included in the top three in the long history of the Demon Race.

Although Jin Chen ignited the magic source relatively early, he only ignited the magic source at the age of eighteen, and according to the conditions, he was not qualified to go to Death Island. Even if for Wen Ying's sake, Grand Duke Ivan sent him to Death Island, and actually let Jin Chen return after sixteen years, it is no wonder that Count Alaric finds it strange.

How did Count Alaric know that Wen Ying proposed to let Jin Chen return to Wen Ying after sixteen years, just because according to the prophecy of the three-star castle, Grand Duke Ivan had become a slave at that time, and Wen Ying was worried that the longer Jin Chen stayed on Death Island, the more dangerous his life became.

"What about the undersea seal world?" Grand Duke Ivan did not answer Wen Ying's words, he kneaded one of Wen Ying's small hands and said to Count Alaric.

In the eyes of Grand Duke Ivan, if Jin Chen does not open the Magic Source Cave Heaven, even if he reaches the Burning Realm, it will not be of much use to return to Wen Ying's side, and his promise not to let Jin Chen die is already the biggest concession.

Seeing Ivan openly asking Count Alaric, Wen Ying knew that it was inconvenient for her to speak again, so she fell silent.

"The wizard has analyzed more than 20 kinds of materials from the detritus of black snow, which should be related to the refining of heteropolar crystal ore." Count Alaric said: "I have arranged for a million demon people, worked hard for a hundred days, and flipped through all the books on the Seven Continents of Heaven, including the books in the homes of the human slaves, one by one, page by page, and still did not find any record of the refining method of heteropolar crystal ore." ”

On that day, in the undersea sealing world, the time flow spell could not be cast, but the dark crystal wizards cast a restoration spell to restore all the lava vessels, twin barrels, weapon molds, carts and other objects in the undersea sealing world one by one, but without the refining method of heteropolar crystal ore, it is useless.

Since the Dream Palace also did not have a refining method for heteropolar crystal ore, Grand Duke Ivan ordered to adopt the most primitive method, requiring the Heavenly Kingdom, regardless of the gods, demons, or human races, including the aliens living in independent cities on the Seven Continents Continent, to check every book on the Seven Continents Continent to see if there was a record of the refining of the heteropolar crystal ore. There are even bounties offered to the alien races in the sea of light and darkness, but anyone who provides clues about the refining of heteropolar crystal ore will be rewarded. It's just that heteropolar ore spar has disappeared for tens of millions of years, and the records related to heteropolar ore refining have long since disappeared.

After searching like this, I found more than a dozen sites where heteropolar crystals had been mined, and I also found many records or legends about the descriptions of heteropolar crystal weapons, but I still did not find any records directly related to the refining of heteropolar crystals.

Count Alaric raised his hand, and a booklet bound in thick parchment appeared on the crystal table.

"This is the information that has been collected about heterocrystalline ores. More than a dozen copies of this booklet have been produced, and they have been sent to the Grand Dukes and King Edward. Count Alaric paused for a moment and continued: "Marquis Harvey arrived at the Sealed Underwater World two days ago, and he proposed to do a few things. ”
