Start your journey to immortality from Naruto

In the rented courtyard, Gu Chen took out some spiritual materials he had bought and directly summoned the Dragon Flame.

Gu Chen threw these spiritual materials into the flame furnace and watched the furnace shaped by the dragon's flame melt these spiritual materials.

In less than an hour, all the spiritual materials turned into liquid.

Gu Chen looked at these liquids, quickly formed seals with his hands, and runes quickly merged into these spiritual materials.

After a short while, the liquid spiritual material inside gradually began to take shape as runes continued to fly into it.

Gu Chen did not stop when he saw this, but continued to draw one restriction after another and flew towards the furnace inside.

Finally, after Gu Chen cast the last restriction into the refining furnace, Gu Chen released his control over the cauldron and watched it slowly fly up.

Seeing this scene, Gu Chen nodded with satisfaction, took out a drop of blood from his body and injected it into the cauldron.

When the essence and blood of the Taixu ancient dragon in the Nascent Soul stage of Gu Chen merged into the furnace, it was instantly absorbed by the furnace.

The power of time and space contained in Gu Chen's essence and blood, combined with the restrictions that Gu Chen had previously carved, merged together, and marks of the Taixu ancient dragon appeared on the furnace.

As the furnace emitted powerful energy fluctuations, a large amount of thunder suddenly gathered in the center of the courtyard.

Countless bolts of lightning struck madly towards the cauldron that Gu Chen had refined.

However, Gu Chen was not worried when he saw this. He waved his hand and threw the floating cauldron in front of him into the calamity cloud above.

After the cauldron entered the calamity cloud, the lid on top slowly opened, continuously sucking the calamity thunder in the calamity cloud into it.

The thunderbolts seemed to be enraged when seeing this. The thunderbolts that were supposed to strike down one by one started to strike towards the cauldron in twos, and then three at a time.

However, this cauldron seemed to have infinite storage space inside it. All the thunderbolts were directly absorbed by the cauldron before they struck it.

When the calamity clouds dissipated, the cauldron slowly floated down from the sky and slowly fell into Gu Chen's hands.

"Xiao Chen, where did this furnace come from? Why was it struck by lightning?"

Hei Qing watched the cauldron fall into Gu Chen's hands. He looked at Gu Chen seriously and asked Gu Chen.

"This is the Taixu Furnace, a magical tool I made specifically for refining pills. The reason why it can attract thunder is exactly the same principle as the elixir."

Gu Chen looked at Hei Qing with a smile and spoke to Hei Qing seriously.

"The furnace can also be used as a pill. Haha, you are really amazing. But as long as you are okay, I will go out first."

Hei Qing smiled slightly when he heard Gu Chen's words. He observed for a while and found that Gu Chen had no signs of injury. He turned around and walked outside.

After watching Hei Qing leave, Gu Chen quickly took out some medicinal herbs from his storage ring and began to refine the corresponding elixir according to the instructions on the elixir recipe.

The Taixu Furnace is indeed a magical instrument specially refined by Gu Chen. It is very convenient when refining pills.

Because Gu Chen set up a corresponding formation inside it, it can not only refine pills, but also warm and store the pills in the furnace.

The alchemy in the world of Fights Break Sphere is on a completely different level from the alchemy passed down by Emperor Di Shennong.

Gu Chen started from refining first-grade elixirs and continued until he refined eighth-grade elixirs without any mistakes.

When refining these pills, Gu Chen didn't even need to use his mental power to scan the changes in the furnace. He just had to control the flame. After all the pills were refined, the Taixu furnace could even automatically fuse the essence of the medicinal materials extracted by Gu Chen one by one.

Then, the finished pill is refined and flies out of the pill furnace.

When it came to the eighth-grade elixir, it became less convenient for Gu Chen to refine it.

Although Gu Chen was able to fuse the elixir, there were only 8 bottles of elixir, but the most important thing was the spirituality contained within them.

Many times, although Gu Chen only had eight bottles of eighth-grade elixirs, their original medicinal properties did not reach the level of eight bottles, and were only seventh-grade.

Moreover, for the same eighth-grade elixir, the three-color elixir thunder and the five-color elixir thunder have completely different effects.

In order to be able to refine a powerful eighth-grade elixir, Gu Chen had to proceed patiently, observing every change in the alchemy, the adjustments in authentication, and the order of tempering and fusing the medicinal materials.

Sometimes, Gu Chen would even go to the Dan Tower specifically to look for Xuan Kongzi and ask the seniors in the Dan Tower about the taboos in refining pills.

At the beginning, only Xuankongzi, a senior who was very optimistic about Gu Chen, was willing to reveal relevant knowledge. Xuanyi and Tianleizi looked at the young Gu Chen and thought that Gu Chen was making a fool of himself.

However, Gu Chen was not discouraged. After all, if you want to learn something and don't want others to say something about you, how can it be so easy?

However, as Gu Chen came to ask questions again and again, the questions he asked were very coherent, as if they were questions that a person who really studied alchemy could ask.

After witnessing Gu Chen's growth time and time again, Xuan Yi and Tian Lei Zi also recognized Gu Chen.

Although Gu Chen did not take these three as his teachers.

But the three of them did act as Gu Chen's teachers and taught him a lot about alchemy.

With the help of these three people, Gu Chen was able to successfully refine the eighth-grade elixir very quickly.

After refining the eighth-grade elixir with nine-colored elixir thunder, Gu Chen stopped learning alchemy knowledge, put away everything, and went to meet Xuan Kongzi and others for the last time.

Gu Chen deduced what he had gained from alchemy during this period and created a top-grade heavenly-grade fighting spirit cultivation method.

This technique can not only cultivate fighting spirit, but also enable a person's mental strength to undergo continuous transformation as the fighting spirit grows.

In the early stage, it continues to grow, and in the later stage, it continues to increase in spirituality.

After thanking the three giants, Gu Chen found Hei Qing and Zi Yan who were having a lot of fun in the lighthouse, called Qing Lin who was practicing hard, and set out on the journey back to Donglong Island.

Gu Chen plans to practice with all his strength and reach the great success stage as soon as possible.

Although this process requires a lot of spiritual power, the Void Thunder Pool not far from Donglong Island is the best place for Gu Chen to retreat.

There are countless powerful thunder and lightning there. As long as he can refine all of those thunder and lightning, he will definitely be able to reach the Mahayana stage.

Perhaps, that void thunder pool could help him successfully pass the immortal calamity and truly become a real dragon.

After all, thunder tribulations, especially those from the dragon clan, are notoriously violent and brutal, leaving no chance of survival.
