Ling Tian did not leave the secret room for a day and a night.

On this day and night, the Oriental family Dongfang Thunder bid farewell to the Chengtian royal family, led the crowd to leave Chengtian, and embarked on the return journey. The Northern Underworld family also withdrew from Chengtian almost at the same time.

The three heads of the Nangong family asked to see Ling Tian several times, but they were all stopped in the early morning. And the news from the Lingfu Courtyard and various places, including the movements of the Yang family and Qian Shuirou's movements, etc., was almost completely suppressed in the early morning.

Everything, just waiting for Ling Tian to come out of the secret room!

Ling Chen and Yu Bingyan were not at ease with Ling Tian, they didn't sleep for a day and a night, and the two of them walked around in front of the door of the secret room, you come and go. The cooked meal is hot and hot, then poured out, then cooked again, then heated again, and poured out again...... And so on and so on more than a dozen times...... Ling Chen's skills are pure, although he hasn't slept all night, he hasn't been tired yet, Ling Tian has also done similar things before, and he has practiced in retreat and medicine many times, although he cares, he is still at ease!

It was the first time for Yu Bingyan to wait for Ling Tian, and she was worried about herself, especially from the early morning, she knew that the main purpose of Ling Tian's retreat was to refine the key medicine for herself to treat the Xuanyin Divine Vein, which made the little girl extremely moved, and she almost cried out loud, and her heart became even more uneasy. His own Xuanyin Divine Vein, as the number one family in the world, the Jade Family was helpless, there was no way, what good way could Ling Tian have? You must know that refining medicine is an extremely depleting job, if Brother Tian consumes his body because of refining medicine for me, whether the medicine is useful or not, it is my sin?

Alas, my silly brother, don't you know that Yan'er would rather never cure her illness than have any damage on you?

In this night's time, in the feelings of the two women, they both felt like a year, especially Yu Bingyan. At first, the two of them could still talk to each other to pass the time, but later, both of them closed their mouths tightly, their eyes fixed on the door of the secret room, and their faces were full of anxiety and worry.

Ling Tian in the secret room had really reached a critical moment. In order to refine the "Superb Great Returning Pill" this time, Ling Tian thought that he had prepared quite well, and all the medicinal materials were in excess of the reserves, adding two catties to the full; even before that, Ling Tian had secretly tested the Great Returning Pill twice with ordinary medicines according to the refining method of the Great Returning Pill, and each time it was quite successful, so Ling Tian was full of confidence in this alchemy.

Ling Tian never imagined that actually refining the best elixir and experimenting would be two completely different things. In particular, the thousand-year-old blood participation in the ice crystal fire lotus, although it is a complement of civil and military, it is also a different furnace of ice and charcoal, which is difficult to reconcile.

After extracting the essence of the other twenty aftertaste auxiliary medicinal materials in turn, it was similar to the previous two experiments, and there was no mistake, but it was a pity that Ling Tian confidently put the Ice Crystal Fire Lotus and the thousand-year-old blood ginseng into the Dan furnace together, and was extremely careful to trigger the open flame, who knew that as soon as it was heated, the two peerless elixirs inside collided with each other, each occupying a corner, and the well water did not interfere with the river water, and it was distinct. This has been the case several times in a row. This gave Ling Tian a big headache, if the two main herbs blindly contradicted and could not be fused, how could they be alchemized? Moreover, these two herbs could not be divided and disposed of like other medicinal materials, otherwise, as long as the aura leaked slightly, the medicinal power of the pill would be greatly lost.

In desperation, Ling Tian had no choice but to take the most stupid method, his right hand continued to control the fire, and his left hand held a jade short sword, which was against the Dan furnace, passing on the power through objects, and locking the two elixirs with his most exquisite internal force to prevent them from separating. But in this way, Ling Tian suffered a lot!

Refining medicines, the most taboo is the intervention of foreign objects belonging to the genus of hardware, probably only jade items other than hardware can be an exception, but jade items are the most fragile, and it is extremely difficult to channel internal forces, and the Dan furnace is more steel, almost half a foot thick, Ling Tian only seeks its strength when casting, and it is naturally extremely bulky. Now the internal force must first control the Dan furnace through the jade short sword, and then control the medicine remotely through the wall of the Dan furnace; invisibly, it will consume several times more internal force! It is not that Ling Tian does not want to directly use his hand to touch the Dan furnace to exercise power, but if that happens, once the temperature rises, it will inevitably roast Ling Tian's palm to pieces, and Ling Tian's skill is high, but it cannot compete with the natural high temperature.

However, this kind of luck is the most exhausting power, with Ling Tian's extremely pure innate dragon divine skill's ninefold power, it only lasted less than an hour before he felt powerless, and now the two main medicines in the Dan furnace have just begun to melt!

However, the fire can not continue to increase, it must not be angry, unhurried, both civil and military, and maintain a constant temperature, which is the best way to alchemy. Once you are in a hurry, I am afraid that the elixir in the Dan furnace will inevitably turn into a furnace of waste slag!

It's hard to ride a tiger now!

No matter what, it must be successfully refined! Ling Tian's eyes were clear and calm, and he kept his true power flowing out continuously, and simply closed his eyes and concentrated on his exercises. The right hand mechanically controls the fire, and everything is calm and quiet, but under the calm appearance, there is a danger like boiling magma!

Two hours passed...... Three Hours...... There were thin beads of sweat on Ling Tian's forehead, and his face turned slightly pale.

Six hours passed, Ling Tian's face was covered with sweat like rain, his hair was tightly clinging to his face, his clothes were as if he had just been fished out of the water, his face was abnormally pale, only his cheeks revealed a little unhealthy redness, the blue tendons on his forehead were beating suddenly, his upper and lower teeth were clenched tightly, and his cheeks clearly bulged out with a fleshy edge...

Ling Tian himself had never imagined that in the two hours of the experiment, when it came to the actual refining of the Great Returning Pill, it would become six hours before the full work was completed! The Dan Furnace was like a bottomless abyss, absorbing all of Ling Tian's incomparably thick innate true qi, draining it and waiting to be exhausted.

Ling Tianli has now reached the point of exhaustion! His eyes were also blurry, and a strong thought of not admitting defeat rose from the bottom of his heart. Ling Tian's eyes widened in anger, he roared wildly, and the last trace of true qi flowed into Danding along the jade short sword, and as soon as his eyes went dark, he lost his consciousness. Before losing consciousness, faintly, there seemed to be a strange smell in his nose, and Ling Tian's mind was relieved, and he fainted.

I don't know how long it took, Ling Tian woke up slowly. The fire under the Dan furnace was no longer extinguished, looking at the Dan furnace in front of him, Ling Tian actually had an indescribable subtle feeling from the bottom of his heart, when he was suffering from gains and losses, he didn't have the courage to open the Dan furnace to see what was going on.

Taking a deep breath, Ling Tian settled down and sat up slowly, only to find that his whole body was soft and lacklush, without half of his strength; haha laughed, stretched out his head and stabbed it, and shrunk his head with a knife, even if he really failed, he had to know a result. At that moment, he no longer hesitated, stretched out his right hand, and removed the top cover of the Dan furnace. As the lid of the furnace was slowly opened, a strong smell suddenly came to the nostrils, instantly filling the entire secret room. Ling Tian suddenly felt extremely comfortable all over his body, and his limbs seemed to be infused with strength, and he relaxed.

At the bottom of the Dan furnace, there were more than 100 blood-red crystal clear pills the size of broad beans, all round and transparent, like crystal agate. Bursts of strange fragrance emanated from these pills, and just smelling their aroma made me feel very relaxed.

Ling Tian closed his eyes, and after a sense of relief in his heart, a feeling of complete ecstasy rose. At this moment, Ling Tian almost wanted to sing out loud!

This is a large number of Great Returning Pills, which means that Ling Tian's invincible force is about to come out! With the skill of Ling Jian and the others, if he subdues this Great Returning Pill and increases his strength by twenty years, his personal strength will be enough to dominate the world! Except for a few people, there is no invincible opponent!

At such a critical moment when war was about to break out, his strength had suddenly increased by such a big step, and today, Ling Tian already felt that he no longer had any scruples!

Hurriedly took a few jade bottles that had been prepared on the side a long time ago, carefully packed the large pills into them, tightly plugged the bottle mouth, and confirmed that all the large pills had been collected, this time he breathed a long sigh of relief, and in an instant, an indescribable feeling of fatigue rose up, and he was almost drowsy. Ling Tian pinched his thigh fiercely, and under the severe pain, suddenly the Lingtai was clear, now was definitely not the time to sleep, but it was the best time to recover his strength.

He took out a large pill and put it in his hand, Ling Tian sat cross-legged on his knees, and dived into the internal force technique of the Dragon Shocking Divine Skill. At first, I only felt that the dantian was empty, and gradually there was a trace of thin internal force swimming in the body, the speed became faster and faster, and the residual internal force in the meridians of the whole body was swept away, and a torrent of internal force was gradually formed, which stirred up in the dantian. Ling Tian clearly felt that after his internal strength had been consumed by the essence of today's time, it seemed that he had made another stage of progress in recovering again!

Taking advantage of the moment when the internal force was running to the extreme, Ling Tian took the Great Returning Pill in the palm of his hand into his mouth, and immediately felt a cold silk thread flowing down his throat, and then a powerful and gentle warm current erupted from the dantian! A powerful medicinal power rose from the dantian, and instantly traveled all over the body, and immediately the whole body became hot as if it was on fire.

Ling Tian worked hard to control his own internal force, guiding this powerful external force, and according to the running route of the Amazing Dragon Divine Skill, he ran step by step in the meridians of his whole body!

Boom! The true qi of the whole body seemed to be ignited at the same time! The golden crown of hair on Ling Tian's head suddenly exploded, and his long black hair actually rose straight into the sky, and a strong air flow rushed out from the inside of his body, and the fine white brocade robe on Ling Tian's body was torn into pieces all over the sky by the violent energy, and he was suddenly naked!

Ling Tian guided the powerful force that had sprouted from this Great Returning Pill, trying to merge with his own strength, but after a long time, to no avail, the two internal forces separated as soon as they came into contact, and it turned out to be the appearance of well water not violating river water.

Thinking of this, Ling Tian's eyes suddenly widened angrily, and he turned his heart sideways, directly using all of his own power, mixed with external huge forces, and frantically slammed towards the tenth layer of the Amazing Dragon Divine Skill!
