The Yin Yang Xuanling Pill can be said to be the highest-level elixir that Zhang Tong has seen so far, and it is many times more difficult to refine than ordinary pills!

Fortunately, Zhang Tong had refined a lot of pills to replenish his true qi before, so he was able to maintain the furnace fire for such a long time and ensure the progress of alchemy.

However, at the moment of Dancheng, Zhang Tong only felt that the true qi in his body began to riot, and even the Yin and Yang Taiji Diagram began to rotate rapidly......

Knowing that he is now on the verge of breaking through, it is not possible to forcibly suppress it, and I am afraid that it will damage his meridians and dantian at that time, so Zhang Tong didn't even have time to say a word to Feng Shayan and the two girls, so he directly took his elixir, rose to the sky, and quickly came to the top of a mountain, ready to spend his golden pill here!

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

Zhang Tong quickly adjusted his state.

He sat cross-legged with a quiet expression, his mind was completely opened, and he slowly understood the changes before the breakthrough.

In this perception, the innate Taiji diagram composed of yin and yang true qi in the dantian is constantly condensing and rotating, and all the meridians and points in the body are constantly communicating with the outside world, wantonly devouring the huge spiritual power of the outside world to enhance the true qi content in the dantian.

With the operation of Zhang Tong's innate yin and yang technique, countless rune lines composed of true qi appeared in the meridians of his body, intertwined and rotated.

And in this interweaving and rotation, these rune lines began to reorganize rapidly, turning into a large array of runes engraved in Zhang Tong's body......

This is the method of condensing the golden pill in the immortal dao exercises, and the reason why the yin and yang technique practiced by Zhang Tong before could not condense the golden pill is that it lacks this indispensable method!

The runes were cast, and Zhang Tong at this time turned into a heaven and earth oven.

Zhang Tong's body erupted black and white air currents around the surface of his body, and these air currents were the yin and yang true qi in Zhang Tong's body, and at this time, these yin and yang true qi had become like mercury, almost liquefied.

At the same time, Zhang Tong's Five Elements Refining Technique also absorbed these true qi to the greatest extent, constantly transforming Zhang Tong's five internal organs, and then using this as the root, he began to refine Zhang Tong's whole body.

The powerful force in the body is rolling, and the muscles of the whole body, even down to the cells, the surging energy of the five elements flows everywhere, constantly refining the muscles, muscles and bones.

When Zhang Tong's physical strength reached a certain critical point......

The true qi in the meridians is like the Yangtze River, which begins to pour in and merge into the sea of dantian qi......

Hundreds of rivers flow eastward and finally enter the sea!

All the luck has come true!

"Buzz!"

As the true qi converged, the innate Taiji diagram in Zhang Tong's dantian began to tremble continuously.

Zhang Tong's brows furrowed, and his face showed unprecedented solemnity.

"It's not the time yet, we have to keep ......!"

But at this level, it is absolutely difficult to continue to cohesion!

At this moment, Zhang Tong relied on the subtle induction of his mind to control the operation of the True Qi River, and with a flip of his right hand, a black and white round elixir appeared in his hand.

Swallow it in one gulp.

This Yin Yang Xuanling Pill instantly turned into a stream of pure energy and poured into Zhang Tong's Dantian.

With the energy of the Yin Yang Xuanling Pill entering, the Yin and Yang Taiji Diagram in Zhang Tong's dantian shook suddenly, and then Zhang Tong found that a black and white flame suddenly appeared around it, flying into the long river of true qi.

As soon as this flame entered the long river of true qi, it was like pouring water into an oil pot, violently vibrating and boiling.

However, this black and white flame was washed away by the tides of those true qi, and it was still stubbornly and slowly scorching everything.

As time slowly passed, the entire long river of true qi became more pure and condensed.

"Boom!"

When this kind of condensation reached the extreme, the Yin and Yang Taiji Diagram shook suddenly, and then Zou Ran took the center as the origin and began to shrink rapidly!

All the true qi rivers were also completely absorbed by this origin in an instant, making Zhang Tong feel that his body was suddenly empty, and a huge sense of emptiness came, almost making his whole person languish.

However, all of this was just between lightning and flint, and between the swallows and spits of the origin point in the dantian, the Taiji diagram in Zhang Tong's body had turned into a dripping pill, spinning rapidly in the dantian.

Streams of liquefied energy flowed out of the golden pill, instantly filling all the meridians in Zhang Tong's body......

Jin Dan has been completed, and at this time, Zhang Tong's body can no longer become true qi, but true yuan!

At this time, Zhang Tong's soul also soared, and he directly probed into his body.

At this time, at his dantian, a black and white "Golden Pill" was spinning dripping......

Surrounded by the same black and white flames, they were constantly burning, and the external aura they absorbed was burned before absorbing and transforming......

"I didn't expect that this Yin Yang Xuanling Pill would help me so much, and it actually allowed me to condense my natal true fire in advance!"

Zhang Tong looked a little surprised.

The effect of this Yin Yang Xuanling Pill was obviously beyond his expectations.

But now is not the time to rejoice.

Because at this time, the breakthrough process has only just gone halfway.

Zhang Tong raised his head slightly.

At this time, the sky had turned dark red, giving the entire bare mountain a sense of oppression.

A huge vortex appeared in the center of the sky.

The electric snakes appeared in the dark red sky, and the electric snakes were absorbed by the whirlpool, and in just a moment, the whirlpool stopped spinning and turned into a purple cloud.

Dark red sky, purple clouds, flickering electric snakes.

Everything indicates that a catastrophe is coming!

Zhang Tong stood quietly with his head held high, motionless.

The only difference between a human monk and a heterogeneous monk is the Heavenly Tribulation of this Formation Period.

Since Hongjun Old Ancestor joined the Dao, the Heavenly Dao has been completed, and since then, all monks need to go through the test of the Heavenly Tribulation before they can continue to embark on the road of pursuing the Great Dao.

This is also to tell all cultivators that the Great Dao is hard to find, and if you want to truly embark on this path, then you must have a tenacious Dao heart and an unyielding will!

As for the alien immortal cultivators, this Heavenly Dao test is also mixed with the Transformation Heavenly Tribulation......

The power of that kind of Heavenly Tribulation is almost several times that of a human cultivator!

At least seventy percent of the outliers will fall at this level.

This is also the reason why the fox demon Hong Xue shouted "Heavenly Injustice".

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

The sky was still cloudy, and low thunder began to sound one after another.

Zhang Tong knew that this was a sign that the thunder tribulation was about to fall......

"Boom!"

A purple thunderbolt fell directly from the sky at a high speed, and it slashed angrily at Zhang Tong who was standing there.

At this time, Zhang Tong looked at the purple thunder and lightning, his body did not move, and he had no intention of using spells or even magic weapons to resist.

In the blink of an eye, purple lightning struck him directly.
