In fact, with Jiang Xincheng's alchemy, plus the assistance of the artifact Sheng Tang, it is not that he can't refine the sixth-grade lower level Buyun Dan, but the success rate is low, at most one percent. Pen ~ fun ~ pavilion www.biquge.info

In other words, if Jiang Xincheng exerts a super level of one hundred materials, he can use one hundred materials to refine one Buyun Dan, but if he wants to pass the test of the Ancestral Gate, he must use ten materials to refine one Buyun Pill, and Jiang Xincheng's success rate is not so high at all.

Originally, he thought that the test of the Root Ancestor Gate would be the elixir of refining the fifth grade lower rank, but he didn't expect that the difficulty of the test of the Root Ancestor Gate would soar, and he actually asked him to refine the sixth-grade lower level Buyun Dan, Jiang Xincheng couldn't help but smile bitterly.

After thinking about it for a while, Jiang Xincheng finally decided not to carry out the test of the Ancestral Gate for the time being, and first to improve the alchemy in the main trunk of life, and when the alchemy was raised to the upper level of the fifth grade, he should be able to refine one Buyun Pill with ten parts of Buyun Dan's materials.

The plan has been decided, Jiang Xincheng no longer hesitated, found a place with the thickest life mist in the backbone of life, took out a piece of materials from the ring, and began to improve the alchemy.

There is an artifact in the Tang Dynasty to check and fill in the gaps all the time, plus the artifact in the Tang Dynasty makes Jiang Xincheng's alchemy speed soar, and there are a large number of spiritual materials in the Na Ring and the Tang Dynasty space for Jiang Xincheng to squander, when Jiang Xincheng put all his time into alchemy, alchemy soared.

Time is like flowing water, gone forever, when Jiang Xincheng raised the alchemy to the upper level of the fifth grade, half a year has passed, and in this more than half a year, hundreds of thousands of alchemists have passed the test of the Gate of Eternal Leaves, and entered the different leaves of life to enjoy the huge life force inside.

There are also one hundred and ten alchemy geniuses who have passed the test of the second level of the Golden Branch Gate, which has caused an uproar in the huge life ancient tree world, but although these people are in the limelight, they still can't catch up with Jiang Xincheng, so far he is still the first to pass the test of the third level of Wang Gan's Gate, and the only alchemist who has passed the test of Wang Gan's Gate.

On the Killing Domain and the Platform of Life, there were thousands of cultivators who were jealous of Jiang Xincheng, the only one who had entered Wang Gan's Gate, including the Heavenly Tiger Realm Overlord and the Divine Dragon Realm King.

It's a pity that although the strength of these Heavenly Tiger Realm Overlords and Divine Dragon Realm Kings is very strong, many alchemy techniques are not very good, and they can't even pass the test of the Yongye Gate, so they can only absorb the thin life force on the Life Terrace.

As for the Heavenly Tiger Realm Overlords and Divine Dragon Realm Kings who had remained in the Killing Domain so far, their level of alchemy was extremely poor, and the third level task issued to them by the Ancient Tree of Life was too difficult, and they simply couldn't get enough Life Tokens to ascend to the Life Platform.

Although these people can also get some benefits from the Ancient Tree of Life World, they are pitiful, compared to those alchemy geniuses who have passed the ultimate test, they are just soy sauce, let their strength be at the top, but unfortunately the four supreme places of training do not value strength, only alchemy.

Half a year passed in a flash, and after half a year, Jiang Xincheng came to the front of the Ancestor Gate again, took down a copy of the materials of Buyun Dan, and began to refine Buyun Dan.

Buyun Dan is one of the easiest elixirs to refine among the six elixirs, there is only one difficulty, that is, the fusion of 3,570 kinds of spiritual grass spiritual materials, as long as you can pass this difficulty, the rest of the levels are not at all, Jiang Xincheng has absolute certainty to pass.

The first step in refining Buyun Dan was naturally to deal with the spirit grass spirit material, and the same spirit grass spirit material was quickly handled under Jiang Xincheng's skillful hands, and Jiang Xincheng began to refine the Buyun Dan.

The Dan furnace used to refine Buyun Dan is a thousand-eyed furnace at the lower level of the prefecture, and it is also the treasure of the Qi family, if it were not for Jiang Xincheng's great contribution to the Qi family, the Qi family would not have given this treasure of the town family to Jiang Xincheng.

With the Thousand Eyes Furnace in hand, Jiang Xincheng's difficulty in refining Buyun Dan was reduced by a few points, and the first hundred and ten steps of refining Buyun Dan were successfully passed, and soon he came to the most difficult step - fusing 3,570 kinds of spirit grass spirit materials.

When refining the five-grade elixir, it generally only needs to fuse more than 1,000 kinds of spirit grass spirit materials, but once it reaches the realm of the sixth grade, it also needs to fuse more than 3,000 kinds of spirit grass spirit materials at a minimum, which seems to be only three times more than the number, but its difficulty has increased by at least dozens of times.

The greater the number and variety of spirit grass spirit materials fused, the greater the difficulty will be, and this difficulty increases in geometric multiples, not as simple as 1+1=2.

Taking a deep breath, Jiang Xincheng maximized the auxiliary effect of the artifact Sheng Tang and began to fuse the spirit grass and spiritual materials.

The first type of spirit grass...... Perfectly blended.

……

The second type of spiritual material...... Perfectly blended.

……

The Tenth Spirit Grass...... Perfectly blended.

……

The hundredth spiritual material...... Perfectly blended.

……

The thousandth spirit grass...... Perfectly blended.

……

The 1,500th Spiritual Material...... Perfectly blended.

……

Until the two thousand kinds of spiritual materials, Jiang Xincheng was still a perfect fusion.

With a slight smile on his face, Jiang Xincheng concentrated again and began to fuse the two thousand and one spirit grass, but unfortunately this time it was only qualified to fuse, and it did not reach the level of perfection.

Frowning slightly, Jiang Xincheng was not too worried, and began to fuse the spirit grass spirit material again.

The two thousand and three spirit grasses...... Fusion.

……

The two thousand and fifth kinds of spirit grass...... Perfectly blended.

……

The two thousand and ten kinds of spirit grass...... Perfectly blended.

……

The 2,100th Spiritual Material...... Perfectly blended.

……

The 2,500th Spirit Grass ...... Perfectly blended.

……

3,000 Spirit Grass ...... Fusion.

……

Jiang Xincheng took a deep breath, rested for a while, and began to fuse the spirit grass spirit material again, as the number of fused spirit grass spirit materials increased, its difficulty became more and more, even with the help of the artifact Sheng Tang, layers of sweat oozed from Jiang Xincheng's forehead.

The speed at which the power of the divine soul is consumed is extremely fast, but fortunately, Jiang Xincheng has already raised the power of the divine soul to the peak consummation of the late stage of the green sky, which is enough to compare to the ordinary king of the Divine Dragon Realm, which can support him to refine the Buyun Pill.

Now that the three thousand spirit grass spirit materials have been fused, there are only five hundred and seventy kinds left, as long as the five hundred and seventy spirit grass spirit materials can be fused, Jiang Xincheng can successfully pass this most difficult level, so as to refine the Buyun Pill.

Once Bu Yundan can be recognized by the Gate of the Root Ancestor, Jiang Xincheng can open the Gate of the Root Ancestor that has not been opened for hundreds of thousands of years, step into an unprecedented new world, and obtain the majestic and endless life force behind the Gate of the Root Ancestor, so as to set foot in the Heavenly Tiger Realm and become the overlord of the Heavenly Tiger Realm.

Taking a deep breath, a dazzling brilliance crossed Jiang Xincheng's eyes, and he began to concentrate on fusing the spirit grass spirit material again...... (To be continued.) )
