Defying the Martial Way to Burn the Heavens

After Zuo Feng had refined those white metal hemispheres, he had a feeling that refining equipment was definitely much easier than refining medicine.

But what happened later also completely shattered this idea that had just emerged. His original feeling was definitely an illusion. He also really understood why the best equipment was so expensive.

"Bang"

A dull explosion sounded outside Zuo Feng's courtyard. This abrupt sound was no longer as eye-catching as it was at the beginning. Zuo Feng looked up at the rising ball of fire and smoke in front of him, as well as a large pit newly added in the courtyard, and couldn't help but shook his head secretly.

His eyes fell back on the small tripod in front of him intentionally or unintentionally. This tripod was no longer the small tripod he bought back. The small tripod he bought before was scrapped due to an explosion when he first fused the flame crystal with the metal hemisphere. If Zuo Feng hadn't reacted quickly and escaped from the hut before the explosion, he probably wouldn't have to worry about the spiral tower trial anymore.

He had made some progress in fusion only after destroying two cauldrons. After that, the cauldrons were never destroyed again, but there were seven or eight more holes in the yard. Although he was able to throw out the semi-finished Yanjing Fire Thunder in time before the smelting became unstable, he still had not completed a Yanjing Fire Thunder.

Staring at the cauldron in front of him with a frown, the problems in Zuo Feng's production emerged in his mind one by one. The fusion of the metal hemisphere and the Yanjing would become extremely unstable due to the high temperature. At this time, the subtle control of the spirit energy over the flame became crucial, and even a small deviation would cause the entire fire thunder to enter the start-up state in advance.

If this problem could not be solved, his plan to make Yanjing Fire Thunder would be completely ruined. However, the control of the flame requires continuous accumulation of experience, but what Zuo Feng lacks most now is time, and there is only more than a month before the trial.

Zuo Feng, who was anxious, stood up subconsciously and then walked out of the house. Looking at the small pits on the ground, he still remembered the shocked expressions of Zuo Hou and others when they ran to see him anxiously after the previous explosions. Suddenly, a cool breeze blew through the courtyard. Feeling the slight coolness, Zuo Feng also remembered that it was already autumn.

They had been in Yancheng for more than three months. Recalling the many things that happened during this period, Zuo Feng had to sigh that the world is changing. If I hadn't had the help of friends, if I hadn't met that "Huansheng", if I hadn't...

"Hmm?"

When Zuo Feng recalled Huansheng, he couldn't help but frown, as if something had been forgotten. After a little thought, Zuo Feng's face showed joy, and then the telekinesis extended to his palm, and a crystal jade bottle instantly appeared in Zuo Feng's palm.

Feeling the slight coolness in his palm, the "Cold Condensation Ice Mist" that Huansheng had given him, he only used it once when killing the Great Elder, and there should be a lot of cold air left in it. Since the temperature is too high when refining fire thunder, this little thing should be able to solve this problem, or at least alleviate it.

With a look of joy on his face, Zuo Feng returned to the house again. This time, after closing the door, it was five days before he opened it again. When Zuo Feng walked out of the house again, although his face was exhausted, his eyes were filled with unconcealed joy.

After a simple wash and change of clean clothes, Zuo Feng made some changes to himself and left Yancheng.

Outside Yancheng is a vast plain. Zuo Feng crossed the plain and entered the forest without stopping. He was very careful to pay attention to the movements around him, and only stopped in a clearing in the forest after confirming that he was not being followed.

After Zuo Feng stood still, he carefully took out a small silver-white metal ball from his arms. The ball was smaller than a baby's fist, and there were tiny holes and faint cracks on the surface. Zuo Feng looked at these cracks and sighed helplessly.

He thought of a way to temporarily alleviate the instability when refining the fire thunder, which was naturally to use the "cold condensed ice mist" to rapidly cool the fire thunder, so that it could be forced into a stable state when the flame was not properly controlled. This method really could avoid the instability during smelting as Zuo Feng guessed.

But after the actual operation, Zuo Feng discovered another disadvantage. That is, when the high-temperature fusion was suddenly poured with the extremely cold air, it would actually cause the metal on the surface of the fire thunder to produce a trace of irregular cracks.

He sighed helplessly. With Zuo Feng's current level of refining, it was not easy to make this "Flame Crystal Fire Thunder". Although there were some small flaws on the surface, it was barely made successfully. Because he didn't want to continue to destroy the ground in the courtyard, Zuo Feng wanted to come here to try whether this thing was really useful.

With a thought, a trace of spiritual energy passed through his palm into the fire thunder in his hand, and the temperature of the fire thunder in his hand began to rise sharply in almost the blink of an eye. With the extremely unstable characteristics of the fire thunder in his hand, Zuo Feng, who had experienced many failures, dared not hesitate and threw it far away.

Zuo Feng had already spotted a small tree as thick as his forearm. The fire thunder rolled a few times and hit the bottom of the small tree. Then, a trace of hot air came out from the cracks on the silver-white surface of the fire thunder, and the outside of the sphere began to deform slightly. This change was carried out in an instant, and then a flash of fire flashed up.

"Boom"

A dull explosion spread, and the flames flew around with pieces of silver-white fragments. Zuo Feng narrowed his eyes to judge the scope and power of the explosion. When the flames subsided slightly, Zuo Feng walked towards the small tree.

"It seems that the power is not too great."

Zuo Feng muttered to himself, while comparing it with the fire bomb that exploded in the courtyard. The bottom of the small tree in front of him, which was as thick as a forearm, was burnt but not broken. The explosion only blew a gap in the bottom of the small tree. Obviously, the cracks on the surface weakened the power of the explosion.

But when Zuo Feng observed carefully again, he made some surprising discoveries. There were small cuts on the surface of the small tree, and some silver-white fragments were deeply inserted into the trunk. Zuo Feng turned his head and looked around, and found that there were some traces of fragment cutting on several trees within a range of two feet.

Zuo Feng's face, which was originally a little unhappy, finally slowly showed a smile. Then he took out a fire bomb from his bosom and looked at another small tree in the distance.

…

Before the city gate was closed, a thin figure wrapped in a black robe entered Yancheng among the hurried crowd. The young man in the black robe had a wide hat on his head, and there was a slight joy in his eyes under the hat. After turning around, the young man disappeared outside the gate of a house.

This young man was Zuo Feng who hurried back from outside the city. The power of this fire bomb was much worse than what Ning Xiao had introduced, but the destructive power barely met his requirements.

Zuo Feng became even busier in the next few days. He divided his time in a day, two hours to refine medicine, two hours to refine equipment, and the rest of the time, except for rest, was all used to adapt to the damn "prison lock" on his left hand. After all, because of the "prison lock", Zuo Feng couldn't even play half of his usual combat power.

Time passed little by little, and during this period Zuo Feng also took the time to go to the "Zuoyun Trading House" on the other side of the house. He was not too concerned about the business of the trading house, but just handed over dozens of packages of "body-building powder" that had just been refined to Zuo Hou. When they heard the name and efficacy of the medicine powder, the group of teenagers were naturally very happy.

After all, the people living in the mountains had never tried to use medicine powder to strengthen their body-building level. Zuo Feng just took a casual turn, and then returned to his courtyard, entering a semi-secluded state.

In the blink of an eye, the three-month deadline was approaching. Early in the morning, Zuo Feng was about to go out to continue to practice the "prison lock" in his hand, and he heard a dull knock on the door.

Zuo Feng, with a puzzled look on his face, approached the courtyard door vigilantly. During this period, he had been on guard against what means Zhang Yu Commander's Mansion would use against him. But since he came back, the Zhang Yu Commander's Mansion has become unusually quiet, and even the people who were sent to monitor it before have withdrawn.

Walking to the door, Zuo Feng peeked out along the crack of the door. Although he only saw a little, Zuo Feng immediately relaxed, smiled and opened the door, and spoke at the same time.

"Uncle Tian, ​​how come you have time today to visit me?"

Uncle Tian said with a bitter smile: "How can I have time? I don't know what you are busy with all day. I haven't seen you in the past few times. The reason I came to see you is naturally for the spiral tower trial."

Zuo Feng was slightly stunned when he heard the old man say this, and then he said with doubt: "Doesn't the spiral tower trial start in three days?"

Uncle Tian looked at Zuo Feng unhappily, and then said with a bit of a smile: "My eldest son Zuo Feng, do you think that the spiral tower trial is in Yancheng? It takes at least two days to get there from Yancheng, so we have to leave today anyway."

Zuo Feng scratched his head a little embarrassedly when he heard this. He didn't ask about the spiral tower trial in detail at the beginning, so he didn't even think about leaving in advance. He grinned at Uncle Tian a little embarrassedly and said with a smile.

"Then wait for me here for a while. I'll go get ready and follow you right away."

Said Zuo Feng, turning around and going to the small room where he made medicine. Uncle Tian stood casually at the door and looked around the yard.

When Zuo Feng walked out of the room, he saw Uncle Tian's stunned expression. Following his gaze, Zuo Feng looked around the yard and said a little embarrassedly, "I tried to make a batch of medicine powder during this period, but I didn't control the temperature well, so it turned out like this now."

Uncle Tian's eyes flickered a few times, and then he looked at Zuo Feng meaningfully. This young man brought him more and more mystery, and at the same time, he also felt that it was definitely a wise choice to invite him to participate in this trial.
