Chapter 7304

If we use the physical way to explain it, it is because of the temperature difference between the inside and outside of the bronze tripod, which causes the phenomenon of thermal expansion and cold contraction.

It is precisely because of this temperature difference that the bronze tripod will burst from the wind direction.

In particular, in this terrible temperature of 2000-3000 degrees, any subtle temperature change inside may cause Zhang Xiaofan to have the risk of "destroying the spent cauldron" in the process of alchemy.

Half an hour later...

at this time, we can see that the wall of the bronze tripod has already turned into a pool of golden liquid under the fire of the fire, and the cauldron wall of the bronze tripod has been turned into a pool of golden liquid under the fire directly at this time.

And from time to time up the gas bubbles, bursts of heat waves are more come!

An hour later...

I saw that Zhang Xiaofan's sweat, which was eliminated by soybean seeds, was rolling down his forehead like rain.

You know, this alchemy itself is not a very easy thing.

Compared with the cultivation, the pressure that we need to bear is just a lot more.

At this time, Zhang Xiaofan's hands kept forming various mysterious and wonderful seals around the wall of the bronze tripod.

However, with the continuous shaping of the seals in Zhang Xiaofan's hands, the position of the bronze tripod mouth curls and white gas rises out. The flame, which was already as high as 2000-3000 degrees, has reached a new height again.

Br. < br. < br. < br. < br. < br. < br. < br. < br. < br. < br. < br. < br. < br. < br. < br. < br.

the golden liquid began to precipitate from the Golden Tripod in the later half of the year.

It seems that the reddish gold mercury is beating constantly in the bronze cauldron and furnace, flashing the light of pale gold...

seeing this behind the scenes, Zhang Xiaofan finally breathed a long sigh of relief in his heart.

Have reached the point before our eyes, it seems that they have basically achieved more than half of their success. After this, the chance of becoming a pill is also improved a lot.

Two hours later....

the huayuandan in the bronze tripod began to take shape gradually. Finally, a thin golden mist came out from the mouth of the tripod. Among the bronze tripod, bursts of danxiang penetrated Zhang Xiaofan's nose like wings.

Hua Yuandan's innate refreshing and calming effect is also raised in this moment!

"Finished --!"

Seeing this, Zhang Xiaofan is also a long spit of turbid gas, the heart that had been high in the throat was finally put back into this stomach by him.

I never thought that the Hua Yuan pill was so refined that it consumed the essence, Qi and spirit of a practitioner.

You know, this Huayuan pill is just a second grade pill, which can only be regarded as the inferior pill. However, compared with the words of Tongmai Dan, the Huayuan pill is only a grade gap.

However, there is no need to compare the refining difficulty between the two in the sky and underground www.novelhold.com , the fastest update of the webnovel!
