After the desolation left, Tang Chen stood quietly at the door for a while, his dark eyes glowing with a thoughtful light, and then turned into a light sigh.

Retracting his thoughts, Tang Chen once again turned his thoughts to the acquired Dragon Snatching Domain, and said to himself in confusion: "The Inner Sect Sect has always been stingy, this time there are so many third-grade elixirs in this low-level Dragon Snatching Domain, what do they want to do?"

When things happen, there must be demons!

This is a sentence that Tang Chen deeply believes in his heart, and there must be a reasonable explanation behind anything that violates the convention.

After thinking of a lot of explanations, Tang Chen couldn't figure it out, so he simply stopped thinking about it, the most important thing now was to find a way to condense the fourth spiritual breath as soon as possible and step into the fourth layer of the foundation.

Thinking of the back when he left in the barrenness, Tang Chen sighed in a low voice, turned around again and walked into the room where Tang Xinyu was, there was a click from the room, and Tang Chen completely locked the door.

In the room, Tang Chen looked at Tang Xinyu who was lying on the bed with pity, and took out an ancient jade from his arms, which was in the shape of a sword, but the size of a thumb.

There were no cumbersome patterns on the ink-colored ancient jade, nor did there be the slightest aura of spiritual power, only the front of the ancient jade, with three dazzling cracks, as if it had been broken a long time ago.

Holding this ancient jade, Tang Chen pursed his lips, slowly walked to Tang Xinyu's bedside, and said softly: "This sword jade was left by the master, although it can absorb the breath of the earth in my sister's body, and temporarily make my sister's vitality no longer pass, but once there is no nourishment of the earth elixir within three days, it will speed up the flow of vitality in the body!"

A determined look crossed Tang Chen's eyes, he put the sword jade in his hand on Tang Xinyu's chest, and said in a firm tone: "I will definitely get the third-grade elixir in my hands and let you wake up completely." ”

Saying this, the ancient jade that had been placed on Tang Xinyu's chest, which had not moved, also began to exude a misty brilliance, and under the illumination of this brilliance, entwined gray lines suddenly appeared on Tang Xinyu's body, that is, the power of the earth!

Under this cute light, the power of my earth hidden in Tang Xinyu's body was completely revealed, like a huge net, enveloping Tang Xinyu, unspeakably weird!

Looking at the gray innate on his sister's body, Tang Chen's eyes were completely gloomy, the situation was even worse than he imagined!

Through the sword jade, Tang Chen could feel that at this moment, a large part of the meridian bones in his sister's body had been petrified, if he really waited until three days later according to what the doctor said, at that time, even if he took back the earth spirit fruit, I am afraid that his sister would have been completely petrified, and there would be no way to return to the sky!

Tang Chen secretly rejoiced!

Immediately, he no longer hesitated, opened his mouth and bit his index finger, the red blood slipped down gently, Tang Chen stretched out his hand, and the drop of blood fell on the sword jade.

Tang Chen's blood fell on the sword jade, and instead of slipping, it slowly merged into the sword jade in a burst of misty brilliance.

The sword jade that was infused with Tang Chen's blood, the brilliance it emitted was even stronger, and there was a faint fierce sword aura wandering out!

Seeing the brilliance emitted by the sword jade producing a fierce sword intent after dripping his own blood, Tang Chen was already surprised.

Legend has it that some warriors have the power of inheritance of powerful people in their bloodlines, one is to inherit the bloodline of their ancestors, which is called the power of bloodline, and the other is to merge with the soul of a warrior who fell between heaven and earth when they are born, and produce changes, which is called the power of inheritance.

There is also a legend that there is a treasure between heaven and earth, and the treasure has a spirit, and the blood recognizes the Lord, relying on this drop of blood can produce a soul connection with the treasure weapon, so that it can burst out with powerful power.

Therefore, for this fierce sword intent, Tang Chen didn't know if this was the power in his own bloodline, or the power of this treasure itself, but thinking about it, the greatest probability should be that this ancient jade was a treasure.

At the beginning, when I saw this sword jade for the first time, it was given by the master, and it was also the master who taught Tang Chen how to use this ancient jade, as well as the various characteristics of this sword jade, which focused on how to use this sword jade to detect the human body and devour the energy between heaven and earth.

Now that I think about it, I'm afraid that when the master taught this sword jade to himself again, he had already expected today's situation!!

When the master went to the Firmament Continent, it is very likely that he found that his sister had been planted with earth seeds, and left the wasteland in order to find a solution.

Tang Chen thought like this, retracted his mind and looked at the sword jade that was devouring the power of the earth in Tang Xinyu's body, through the sword jade Tang Chen felt that the vitality in his sister's body gradually stopped passing, those petrified meridians gradually regained their vitality, and Tang Xinyu's pale face also had a hint of ruddy.

After absorbing so much of the power of the earth, the sword intent generated by the sword jade became even more powerful and powerful, Tang Chen's face changed, and with a wave of his hand, he grabbed the sword jade back into the palm of his hand, if it was allowed to be swallowed by the sword jade, if it could not swallow the power of the earth, it would devour Tang Xinyu's life force.

Taking back the sword jade in time, Tang Chen also slowly breathed a sigh of relief, looking at his sister's slightly ruddy complexion, Tang Chen's face was also happy, absorbing so much power of the earth, although it couldn't make Tang Xinyu wake up, but it was enough for her to survive these few days.

Gently exiting the room, Tang Chen took the sword jade to the big tree in the courtyard and sat down, concentrating and calming, and then spread out the palm holding the sword jade.

The gray innate flow above the sword jade, Tang Chen squeezed his fingertips, and once again squeezed out a drop of blood and fell on the sword jade, and at the same time, the powerful mental power fell on the sword jade through the slightest connection with the sword jade.

After the sword jade in Tang Chen's palm sucked a drop of Tang Chen's blood again, the sword jade shook slightly, and a low but difficult to ignore sword sound came out.

As the sound of the sword fell, the gray innate on the sword jade was all condensed together, forming two warm spirit beads that broke free from the shackles of the sword jade!

Feeling the appearance of the spirit beads, Tang Chen's eyes were quick, and he reached out with his palms extremely skillfully, and grabbed the two spirit beads that emitted yellow brilliance in the palm of his hand.

Feeling that these two spirit beads that relied on the power of the earth in his sister's body were condensed, the overflowing earth aura, the joy on Tang Chen's face was even stronger.

Foundation building monks, there is no distinction between attributes, as long as it is the aura of heaven and earth, it can be refined, and only after opening up the sea of qi, the attributes in the body will be completely fixed, forming a specific or diverse attributes.

Feeling the majestic energy contained in the two spirit beads in his hand, Tang Chen had an absolute grasp of the power of the fourth spiritual breath, which was definitely not weaker than the third spiritual breath after it was condensed.

Although he often relied on the sword jade to devour the energy of heaven and earth, it was only the first time to devour his sister, this time if it wasn't for the rapid erosion of the power of the earth in his sister's body, which made Tang Xinyu face a life-and-death crisis, Tang Chen would not have been able to make up his mind.

But I have to say that these two spirit beads containing the power of the earth are indeed stronger than any condensed spirit beads in the past.

Once the spirit bead was condensed, Tang Chen no longer hesitated, and put one away with the sword jade, while the other one was swallowed in one gulp and refined into the fourth spiritual breath.

As soon as the spirit bead entered the mouth, it turned into a strong force that filled Tang Chen's limbs and hundreds of remains, Tang Chen did not dare to slack off, his mind sank into his body, and he began to control this majestic aura.

As soon as his mind sank into his body, Tang Chen suppressed the three violent spiritual breaths in his body, and used these three spiritual breaths to suppress this majestic earth spiritual aura, but he did not completely crush this power to death!

The power of the earth is the most suitable for refining the body, Tang Chen naturally will not destroy the heavens, suppress one part of the aura, release the other part, and let them run into the body indiscriminately.

This force collided between the meridians and the bones, causing a layer of fine beads of sweat to appear on Tang Chen's forehead, the meridians are the most fragile and sensitive places in the human body, being hit by this force, even if it has been controlled by Tang Chen, but that kind of convulsive pain is really not something that anyone can bear.

The aura hits the meridian bones, and the meridian bones in that place will absorb a part of the aura, making the body more powerful!

In this transformation between impact and absorption, a night passed, and most of the meridians and bones in Tang Chen's body had made great progress, and even his physique had once again reached a bottleneck.

And that aura was only consumed by one-tenth of it, and Tang Chen, who was cultivating, also felt that his physique seemed to be difficult to improve, so he no longer forced it, and the powerful mental power was fully fired, and it only took a moment to suppress this majestic aura.

I don't know if it's because of the sword jade, in Tang Chen's body, when the three spiritual breaths were running, there was also a faint sword sound.

And all the resistance of that majestic aura was dissolved like a snowflake meeting the scorching sun under this sword roar, allowing Tang Chen to condense a spiritual breath.

Condensed a spiritual breath, Tang Chen's mind moved, and the power of the four spiritual breaths operated at the same time, but after a few breaths, he condensed a spiritual breath again, and now, Tang Chen's body already had the power of five spiritual breaths!

However, the two spiritual breaths newly condensed, although they were strong, were far inferior to the previous three, the corners of Tang Chen's mouth grinned slightly, and the magic of thousands of hammers was activated!

It was as if there was a pair of invisible big hands, squeezing the two newly condensed rays together, and with the squeezing, the two spiritual breaths completely burst open, forming an extremely strong impact force.

In the face of this impact, Tang Chen's heart was shocked, he endured the touch in his body, and used the power of three spiritual breaths to suppress this impact, and at the same time, he drank in his heart, squeezing the two bursting spiritual breath forces together again, forming a new spiritual breath.

The first tempering was successful, Tang Chen slowly breathed a sigh of relief, this was only the first tempering, but the feeling given to Tang Chen was more laborious than the original fourth or fifth tempering, fortunately, the physique had been improved, which made the meridian bones have a great bearing on the impact of the spiritual breath explosion.

However, Tang Chen was still sensitive to the fact that as more and more spiritual breaths fused, it became more and more difficult for him to control these powers. The current mental power is already difficult to control the spiritual power that is gradually gaining strength.

After successfully completing the first tempering, Tang Chen breathed slightly for a while, and after letting his mind be in a perfect state, he sank into his body again......

When Tang Chen opened his eyes again, the sky had already darkened, and Tang Chen had also completed the fifth condensation of the fourth spiritual breath, and all the power of the earth in his body had been digested, and after these five condensations, Tang Chen's physique had also reached the maximum limit, if there was still the power of the earth, there was no way to continue tempering, unless the physique broke through again.

But come to think of it, it's impossible in a short period of time.

When he opened his eyes, he saw that it was already dark, looked around, and found that the desolation had not returned, thinking that now he was also condensing his fourth spiritual breath, Tang Chen simply closed his eyes.

Tomorrow is the day when the Dragon Snatching Domain opens, and he has just condensed the fourth spiritual breath, and he must completely control this spiritual breath and adjust his body to a perfect state.

"Capture the Dragon Domain, Earth Spirit Fruit!" Tang Chen muttered softly, and then fell into cultivation......

At the foot of this mountain peak, the barren man sitting outside the cave also opened his eyes, looked at the dim sky and muttered to himself: "The tempering of the fourth spiritual breath has been completed, and in the last night, try to completely fit the fourth spiritual breath!"

As the barren closed his eyes, in the cave, the black-robed figure appeared again, looking at the desolation and exclaiming: "Thousands of tempers, it is really strange, I remember, this spell seems to have been created by the sword saint Tang Wusupreme, how could this Tang Jue have this kind of technique? What does he have to do with Tang Wusupreme? Then Tang Chen is also surnamed Tang ......"

The black-robed man fell into deep thought, and when he mentioned Tang Wusupreme, a look of deep jealousy appeared in his eyes......
