With the materials, the rest is refining, although there is a furnace in the Immortal Mansion, Yang Tianwen did not use it, but still used the carved bronze furnace in his hand to refine. It's not just handy, but because Yang Tianwen's unique touch tells him that this furnace can be sacrificed like a magic weapon and has not been completely sacrificed until now, it must contain a big secret, and when he got this treasure, the compass grandfather's words also made Yang Tianwen realize that this treasure seems to be extraordinary!

Therefore, unless it is necessary or to save time, Yang Tianwen always uses a carved bronze furnace to refine things, and this time is no exception.

However, Yang Tianwen did not refine the weapon immediately, but chose some spiritual materials, these things are only in the immortal realm to refine the refining materials of immortal weapons, and they are rarely encountered in the cultivation world, of course, this does not mean that there are no such spiritual materials in the cultivation realm.

Closed the library door, returned to the cloud bed in the tea room, meditated and cultivated, the top priority was naturally to restore his mana to the peak, because of the knot, the three hundred and sixty-five acupoints of the whole body were filled in, and now although the golden pill has just become an immortal, the tribulation has become an immortal, and the strength has greatly improved, but it still has to refill the three hundred and sixty-five qi sea that has been further expanded.

With the continuous supply of immortal qi in the Immortal Mansion and the special Spirit Gathering Array on the cloud bed, this process is not difficult, but it will take a lot of time, because with the improvement of the mana realm, the capacity of the three hundred and sixty-five acupuncture points distributed throughout the body in the direction of Zhou Tian is also expanding unbelievably, almost the same as the capacity of the lower dantian, so it is an extremely time-consuming task to completely fill them up.

Under the internal view, the Law Yuan Dan hovers non-stop, absorbing the boundless immortal qi from the outside world into the lower dantian for continuous transformation and extrusion, and pressing it until the lower dantian is completely intolerant before the purest and most qualitative white immortal yuan is crossed into the middle dantian and enters the operation, extrusion and further purification. When the immortal yuan in the middle dantian is completely saturated and overflows, this part of the better quality immortal yuan that overflows from the middle dantian will enter the sea of qi to be filled through the operation of nine weeks.

This process was extremely delicate and time-consuming, and Yang Tianwen's powerful mana was only exchanged through such hard training, without any tricks.

Yang Tianwen is not slow to run the True Yuan, but it can't withstand the large number of this sea of qi. This kind of work is not in a hurry, and when the sea of qi is full, the true yuan in the body is constantly circulating, and there is no danger of running out of mana at all. Moreover, in the event of an emergency, the true element of the whole body can be exploded for a short time, which will increase the strength several times, and it can be used to run away or have an advantage over the enemy. Of course, this advantage is just a decoration in the face of a truly completely impossible enemy.

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

When Yang Tianwen came out of the customs, not only was the whole body qi sea completely filled up and restored to the peak period, but the most important thing was that Yang Tianwen found that when Zhou Tian's momentum was formed again, with the Law Jin Dan as the center, the three hundred and sixty-five qi seas had formed a mysterious connection with it, and this connection made Yang Tianwen feel that not only was the true yuan running faster, but also the feeling of seeing the world after leaving the customs was completely different.

Well, let's describe it this way, I used to see mountains as mountains, and water as water. But now it's the feeling of seeing that the mountains are not mountains, and that the water is not water. Every gesture seems to involve this all-pervasive mysterious power. During the exhalation, the whole body was filled with great power, and even a little uncontrollable.

Yang Tianwen did the math, this retreat took at least seventy or eighty years, but it was worth it. The feeling before and after the Yuan Dan Law is completely incomprehensible, and now he is a real scattered immortal, free in the world and at ease.

Oh, by the way, first upgrade the formation disk of the Jiuqu Yellow River Great Array, the texture of the array plate must be pure and hard, otherwise it will not be able to support the huge power input of the Jiuqu Yellow River Great Array. The Black Yao Stone can be said to be the hardest refining stone in the cultivation realm, and it is almost impossible to find a more suitable refining stone in the cultivation realm, only in the Ascending Immortal Realm will there be a refining stone with a better and harder texture than the Black Yao Stone.

However, Yang Tianwen has the advantage of the Upper Realm Immortal Mansion, and has taken out a lot of good refining materials from the treasure house of Cangyao Immortal Venerable, this is really a comparison of goods, he has worked hard in the crystal world for so long, and he has obtained countless superb refining materials that the cultivation realm dreams of, but compared with the inventory in the Immortal Mansion, it is really garbage to grandma's house. It's no wonder that when this Cangyao predecessor ascended, he didn't bring anything, and the most rubbish things in the god realm are probably better than the fairy world? Well, but this is not necessarily, sometimes, there are some good things in the mortal realm that cannot exist even in the god realm, it depends on whether you have the opportunity to get it. After all, the mortal realm is the lowest level of the universe, and it is huge in number and all-encompassing.

The Red Burning Stone is one of the harder refining stones than the Black Burning Stone, and there are orange burning stones, yellow burning stones, and so on on top of it. Of course, there is even the existence of the Black Burning Stone in the Spirit Material Library, but Yang Tianwen's current mana is probably only enough to dissolve the Red Burning Stone, don't look at the Red Burning Stone is only one level higher than the Black Yao Stone, but this level is basically equivalent to the difference between a cultivator and an immortal. Therefore, it is relatively easy for the Red Burning Stone to get a little bit to add to the flying sword, just add some, and the texture of the flying sword will immediately increase by one level.

What Yang Tianwen had to do was to dissolve a large piece of red stone, including the stone core, no matter how big or small a refining stone was, the most central part of it was the most difficult to dissolve.

Yang Tianwen also took some immortal refining materials with the Yin Xuan surname, and prepared to use them to return the Nine Palace Seals of the Pressing Array to the furnace for re-refining. This refining can be said to be a complete renovation of the base of the Jiuqu Yellow River Great Array, the addition of the formation plate, and the addition of the formation center, which is a very big and very hard project.

However, before refining, Yang Tianwen still has one of the most important processes to do, that is, to raise the heart refining pill fire, otherwise no matter how strong the algorithm is, I am afraid it will be difficult to achieve the goal, in short, the preparatory work in the early stage can be said to be perfect.
