Holding the Tsukidan in his hand, Tu Tian carefully closed the door and sat cross-legged on the bed, Tu Tian decided to break through the foundation building period tonight.

Feeling the abundant true yuan in his body, and looking at the Zhuji Dan in his hand, Tu Tian was full of confidence in breaking through the foundation building period this time.

From the Qi refining period to the foundation building period, there is a significant change in the true element, that is, only by turning all the true elements into spiritual elements, this is the real sense of becoming the foundation building period, and it can be regarded as the transformation from mortals to immortal cultivators, which shows the importance of this step.

The quality of the spirit element that has been transformed into this degree will directly determine the achievements after this, so although Tu Tian is full of confidence, he does not dare to be sloppy in the slightest.

Swallowing the Zhuji Dan in his hand, Tu Tian suddenly felt a cool feeling emanating from the bottom of his heart, and then felt an unknown gas emanating from the dantian, slowly assimilating the true yuan in his body.

Tu Tian felt this unknown ability, and secretly observed it, what was certain was that the unknown energy contained in this Zhuji Dan was the purest spiritual element, and its function was to assimilate the true element, making the process of building the foundation simpler.

What Tu Tian can do now is to slowly watch the true element in his body gradually transform into a spirit element, but fortunately, the process is not slow.

I don't know how long it took for Lu Dao, but when the true yuan was half transformed, something went wrong, and this situation caught Tu Tian a little off guard.

When the true yuan had just been half transformed, I saw a blood-red energy that came out of nowhere, wrapping and assimilating the spirit yuan that had been successfully transformed with lightning speed.

"Huh, this is?" The shock in Tu Tian's heart was not trivial, this was about to be transformed, how could this situation occur? And how could there be some familiar feelings when looking at this blood-colored energy?

And just when Tu Tian was surprised, that blood-colored energy had already assimilated half of the spirit element, and even the true element that had not been transformed into the spirit element was quickly assimilated.

When Tu Tian reacted, it was already a step too late, and that blood-colored energy had already assimilated all the true elements in Tu Tian's body, and at this time, Tu Tian's body was filled with this blood-red energy.

The violent and bloodthirsty aura emitted by this energy suddenly understood in Tu Tian's heart, this was the unique spirit element of the Heavenly Demon Strategy, but it was too exposed, and the corners of his mouth couldn't help but show a wry smile.

"This is really troublesome, it seems that it can't be used in front of outsiders in the future, otherwise it will definitely be discovered, hey!" Tu Tian sighed slightly, it seems that God is forcing himself to keep a low profile.

Knowing the reason, although Tu Tian was a little dissatisfied, he had no choice but to take one step at a time, and at the same time secretly warned himself that he must not use it easily unless he was forced to do so, as long as he used it, then he had to kill the other party, otherwise once people found out, then death would not be far from him.

Just as Tu Tian was thinking about his thoughts, he suddenly felt the spirit element in his body quickly spin and pull, and then boundless pain hit his mind.

Tu Tianzhi said, this is the critical moment, the time has come to coalesce the spirit element into the spirit pill, as long as the spirit element covering the whole body is successfully coalesced into the spirit pill, then he is a real cultivator in the foundation building period.

Tu Tian knew in his heart that this step must not be sloppy, and if he was not careful, he would end up with an explosion and death.

Regarding his own life, Tu Tian was unprecedentedly cautious, concentrating all his energy to deal with all this, and his heart was also raised in mid-air.

The blood-red spirit yuan quickly gathered in the dantian, constantly transforming and compressing, removing the impurities in the spirit yuan little by little, so that the spirit pill formed by it was completely flawless, which is also the most important step, refining the qi and transforming the pill, which is directly related to the quality of the spirit pill and the final achievement of Tu Tian.

As the impurities were eliminated little by little, Tu Tian's heart became tighter and tighter, and at this time, he couldn't help but regret a little regret in his heart, regretting such an early impact on the foundation building period, you must know that he had just reached the Great Perfection of Qi Refining now, and the true yuan had just reached the standard, and he had not had time to consolidate it, so he was so anxious to impact the foundation building period.

Just now, when the true yuan was transformed into the spirit element, some had been consumed, this time the spirit yuan gathered the spirit pill, Tu Tian really had no bottom in his heart, and he didn't know if the spirit yuan was enough, if the spirit yuan was not enough when the spirit pill was gathered, then not only all his previous efforts would be in vain, but the consequences would be unimaginable, the light dantian would be broken, and the heavy one would explode and die.

However, now Tu Tian knows that no matter how much he regrets it, it is useless, and the only thing he can do at this time is to pray silently.

"Jade Emperor, Buddha Rulai, Guanyin Bodhisattva, Grandpa of the Land, no matter who of you is on duty today, help me when you hear my prayers, I will definitely give you a lot of offerings. ”

Tu Tian prayed indiscriminately in his heart, although knowing the Dao didn't work, because after all, it was not in their territory, and in this world, he didn't know what kind of great gods the Dao had, so Tu Tian didn't have much hope, just asked for comfort.

"Huh......? This, could it be that they have manifested their spirits?" Tu Tian's mood at this time was like a roller coaster, and he had already lost much hope, but he didn't know where the other pure blood-red energy came out of the road, making the whole scene turn around.

After this energy was added, it immediately rejuvenated the spirit element that had already been outstanding, and I saw that at this time, the spirit element in Tu Tian's body rotated even faster, faster and faster, and gradually formed a blood-red ball the size of a baby's fist.

Tu Tian understood that this was not enough, he had to continue, and the rest of the spirit elements under control at the moment were poured into it vigorously, so that the spirit pill rotated vigorously and compressed vigorously, so that it became more and more refined and pure, and the quality became higher and higher.

I don't know how long it took to do it, but I saw a blood-red elixir suspended in Tu Tian's dantian that rotated around the body, and this elixir was only the size of a jelly bean, but the bursts of violent and bloodthirsty aura emitted between the turns highlighted the extraordinaryness of this elixir.

"Huh......" Tu Tian looked at this elixir, breathed a long sigh of relief, and his heart was full of fear, this is just a good risk, you can't do it in the future, and at the same time, you secretly marvel at the difficulty of cultivating immortals, and the slightest negligence will be the danger of death.

Tu Tian jumped out of bed, after a crackling, Tu Tian suddenly felt that his body was a little lighter, looking at himself in the mirror, he felt that he was a little different from before, at this time he was full of a sense of etherealism, standing there expressionlessly, very like a true immortal.

Secretly narcissistic for a while, Tu Tian's palm was slightly raised, and a blood-red energy ball suddenly appeared in his hand, feeling the power implied in the energy ball, Tu Tian shouted wildly in his heart: Nima, Lao Tzu is finally considered to be a cultivator.

"Hey, it's a pity, it would be nice if it was white, after all, this kind of thing can't be used in front of people. Tu Tian sighed slightly, and couldn't help but secretly say that it was a pity, but Tu Tian just complained, and in general, he was still very satisfied.

Playing with this blood-red energy ball, then Yi Qingyang's shadow appeared in Tu Tian's mind, a trace of coldness flashed in the depths of his deep eyes, and he pinched this energy ball fiercely, and a sneer sneered at the corner of his mouth: "Yi Qingyang, are you ready......
