After that, Lin Yifan's cultivation homework increased suddenly, and those instructors were eager to stuff their lifelong learning and unique exercises into his mind like a duck.

Including various life philosophies and experience against the enemy, they were also taught to Lin Yifan in one ancient mind.

For example, Zheng Shengren told Lin Yifan a truth in a serious voice: "The bitter sage is right, your master Le Zhenren can only hide a knife in his smile, but everyone knows that he is a smiling tiger, and they all guard against him from afar, so this is useless at all! If you want others not to guard against you, don't just pay attention to these superficial efforts, you must insist on being upright, benevolent, and brave, at least on the surface! But at a critical time, you might as well be despicable a few times, just don't let others find out, and if you find out, you won't be smart......

Lin Yifan had another chill, and from then on he was more wary of Zheng Shengren.

Later, he found out that these whining instructors are actually not fuel-efficient lamps, and the words insidious and despicable are simply pediatric when used on them, no wonder they are all Le Zhenren's sworn friends.

When Lin Yifan faced them, he always had the feeling of a little lamb facing a pack of wolves, and he felt that if he was not careful, he would be eaten by them.

Under the guidance of this group of instructors day and night, in the first hundred and eighty-first year of re-entering the illusion realm, Lin Yifan cultivated the rudiments of the Blood Sea Realm, which shocked all the instructors again.

"Dual Realm, you actually cultivated the Dual Realm in the Divine Journey Realm! The sky has eyes, I actually taught a peerless genius that is seen once in a hundred years!" The three-headed and six-armed Zhong Sage once again waved his six arms fiercely, and said loudly with old tears, "Lin Yifan, you have to remember that no matter how high your achievements are in the future, you have always been my student, my Zhong Youquan's student!"

"It's also my student of Song Leshan. Le Zhenren smiled.

"It's also my Li Kusi's student, haha......" The bitter sage also laughed unprecedentedly, and his long snow-white shou eyebrows shook again and again, as if he was about to flap his wings and fly away.

Both Zhenren and Martial Saints are accustomed to taking one word in their names as their own titles.

Generally speaking, the meaning of a name is often very different from the character and destiny of adulthood, with the exception of Le Zhenren and Ku Shengren.

Lezhen's name is Song Leshan, which means "benevolent Leshan", and he also likes to enlighten the mountains in the underworld the most, and the expression on his face is always happy. Only in the three years when Lin Yifan didn't know his life and death, he often had a gloomy face.

The bitter saint's name is Li Kusi, and he has a bitter gourd face, and the expression on his face is always a little sad.

In fact, the fate of the bitter saint's life was also very bumpy, and everything did not go well after coming to the underworld. He cultivated to the Enlightenment Realm during his lifetime, and he was already at the level of a saint, but the level of martial arts was generally not high, and he had only reached the best of the human level. Therefore, when he passed through the Hell Illusion, his thoughts had risen to the middle level of the earth, and he could no longer be reincarnated, so he could only stay in the underworld.

But the bitter saint is a martial artist who takes the route of refining the body, and now he has no physical body, and he can't refine his body anymore, so he can only cultivate his soul and come to a double cultivation of law and martial arts. And it is much more difficult for a martial artist to cultivate his soul than a mage, and there is no sunlight in the underworld, he has been cultivating for hundreds of years, and he has been stuck in the Rizhao Realm, and he has not even cultivated to the Exorcism Realm, and there are still 108,000 miles away from the Soul Exchange Realm that can be reborn.

Therefore, the bitter saint usually has a sad face. When he was teaching his students, this kind of grief and anger would often turn into harsh criticism of the students, which made Lin Yifan very afraid of training under the hands of the bitter saints.

Such a smile like today is extremely rare, and it can be seen that the bitter saint is really happy.

After all, in the Hell Illusion Realm, it is not uncommon to cultivate the Shura Realm and the Blood Sea Realm, but like Lin Yifan, who can cultivate the rudiments of the realm in the Divine Journey Realm, it is once in ten years. As for the iQue Realm, which can cultivate the prototype of the dual realm, it is even more once in a hundred years.

This is enough to make the instructors excited and proud.

It's just that all the instructors don't know that Lin Yifan is actually the owner of the prototype of the triple realm, and what he hides is an extremely rare reincarnation realm, according to Le Zhenren's estimate, this should be regarded as a once in a thousand years.

Lin Yifan's prototype of the reincarnation realm is his real killer feature. Le Zhenren repeatedly told him that he must not use the reincarnation realm unless he had to. Because the killer feature that is known by others is no longer a killer feature, and once this rare field is leaked, it is easy to attract powerful snooping, which brings him a lot of trouble.

Because of this, every time it was Lezhen's turn to train, he refused to allow other instructors to visit and conduct closed teaching, and the focus of teaching was to be familiar with and thoroughly master the rudiments of the reincarnation field.

Ever since he cultivated the Blood Sea Realm, Lin Yifan's cultivation skills had once again skyrocketed at a stunningly fast rate, and the instructors were desperately training him, trying to squeeze every bit of his potential.

Under this kind of high-intensity devilish training, Lin Yifan often had a feeling of extreme fatigue in his soul, as if he would completely fall down in the next moment. But the tenacity honed in the illusion allowed him to miraculously get back on his feet every time he was at the end of the mountain.

............

"These two hundred years of devilish training are really unbearable, but the gains are also great!"

Finally, Lin Yifan once again left the Great Illusion of Hell.

Only two years have passed in the underworld, but due to the hundredfold acceleration of time, in the illusion, Lin Yifan has experienced a full two hundred years of devilish training, which can be described as physically and mentally exhausted.

This time, he was much more miserable than the last time he came out, in addition to his thoughts were dull, he also lacked arms and legs, and even the small half of his face was cut off, which looked particularly terrifying.

This is because in the last training session, the bitter saint wanted to test his sword skills, so he fought with him once. The bitter saint didn't like to keep his hands, so he fought to the end, brushed and brushed a few tricks to split out in a row, Lin Yifan couldn't dodge, so he was seriously injured.

Lin Yifan was not depressed, after all, this body was just a spirit body transformed by thoughts, these injuries were just trivial matters, plus the natural treasures provided by Le Zhenren, the recovery should be very fast.

The two-hundred-year-long devil training in the illusion is undoubtedly painful and arduous, but with every bit of hard work and gain, Lin Yifan's harvest is also very obvious, his soul has been promoted from the middle grade of the human rank to the best of the human level, and he has improved by two grades again, and it is not too far from the ground level.

If an ordinary cultivator's soul quality wants to be upgraded to the next level, it often takes one or two decades of hard work, and there must be enough chance and coincidence. Lin Yifan had never cultivated before, and he was able to upgrade to four levels in a row in just five years, mainly because of the acceleration of the Hell Illusion Realm in a hundredfold time, which was equivalent to taking five hundred years to pile it up. At the same time, this is also thanks to the careful cultivation of Le Zhenren, such as the soul heart fruit and cultivation exercises, and the rotation training of many instructors.

At the same time, after two hundred years of hard work, Lin Yifan's realm is finally about to break through to the Rizhao realm!

Over the years, Le Zhenren has asked Lin Yifan many times to try to absorb the sun essence in the Great Sun Crystal and follow the old path he has walked.

After Lin Yifan comprehended the positivity contained in the sun essence, he carefully absorbed a small trace of the sun essence every time, but the effect of this on the thought was not obvious. Once Lin Yifan was a little anxious and absorbed a little more, but his thoughts were seriously burned, and the soul sea also cracked, and he recuperated for a month, and ate a lot of heavenly treasures before he barely recovered.

After all, thoughts are inherently pure feminine, and the sun is the most rigid and yang, and it is naturally difficult to get thoughts to adapt to and absorb the masculine essence of the sun.

Especially for them who have no physical body, because they don't have the nourishment of the physical body, it is even more difficult to absorb the essence of the sun, much more difficult than in the earthly world.

Because of this, the Rizhao Realm has become the most difficult level of the Underworld Wandering Soul, and it is also common to get stuck in this realm for one or two hundred years.

More than ninety percent of the ghosts and ghosts cannot see the sun for life, and can only wander in the dark.

"Boy, my salary for the next ten years has been eaten by you with medicine, you can take it easy next time you absorb it!" At that time, Le Zhenren said with a wry smile.

After that, Lin Yifan didn't dare to do it like this again. On the one hand, it is to prevent him from going crazy, on the other hand, he also knows that Le Zhenren's income is not high, and after accepting himself as an apprentice, his savings have already been spent, and it is estimated that he still owes a lot of foreign debts.

Le Zhenren really didn't have anything to say about Lin Yifan, the apprentice of the two worlds, he was generous, the expensive Great Sun Crystal, and the Heavenly Treasure of the same value as the Soul Heart Fruit, he threw it to Lin Yifan like a pebble.

If Le Zhenren hadn't helped Lin Yifan so much, he would have hung up a long time ago.

"There are people in the DPRK who are good officials", Lin Yifan is now very glad that he is an earthling, so he can have such an opportunity.

But when Lin Yifan's thoughts broke through to the best of the human level, Le Zhenren immediately stopped, not daring to let him absorb the Great Sun Crystal again. After all, if Lin Yifan really breaks through to the Rizhao Realm, it is possible for the thought level to go up to the level again, and break through to the ground level, then he can't be reincarnated, and he can only stay in the underworld like Le Zhenren and them.

Therefore, after two hundred years of cultivation in the illusion realm, Lin Yifan's current cultivation results have basically reached the limit that can be reached in the underworld, and the time for several major sects to select reincarnated souls is also approaching, so Le Zhenren hurriedly took Lin Yifan out to prepare.

This is a grand event that is only held once every ten years, and once it is selected by these heirloom sects, it is the carp jumping over the dragon gate.

After resting in the cave on the top of the mountain for three days, Lin Yifan fully recovered his vitality, and his limbs were sound and radiant again.
