Chapter 767

In this world of flames, the Fire Spirit was never afraid of consumption. It was just like the illusion where the black shadow was trapped in the first ancient road.

As the two sides fought, loud energy explosions constantly sounded out. Zi Chen suppressed the Fire Spirit with all his strength, but his own consumption was increasing.

In terms of combat strength, the Fire Spirit was weaker than Zi Chen. Every time Zi Chen attacked, he could injure the Fire Spirit. Sometimes, he could even severely injure it. However, the Fire Spirit was in this world of flames, which was equivalent to having an endless supply of energy. As long as it was not a fatal injury, it would recover in the next moment and regain its peak combat strength.

"I have to kill it in one blow. Otherwise, no matter how many attacks I use, it will be useless."

Zi Chen held his spear in the air, a cold light flashing in his eyes. The constant attacks allowed him to see the problem. If he continued to fight like this, he would be the one to suffer. As long as he could not kill the Fire Spirit in one blow, it would instantly recover to its peak state. Then, all his previous attacks would be wasted.

Zi Chen's Abdomen. Extreme Yin and Extreme Yang energy seeped out of his body. Gold and silver light covered Zi Chen. Zi Chen, who was ready to use his full strength, mobilized the two extreme energies in his body at the same time. A powerful aura was released from his body.

The two energies merged into the dragon spear one after another. The silver dragon spear also emitted gold and silver light in an instant. The two extreme energies revolved in the dragon spear. A crazy and tyrannical aura emerged after a loud dragon roar, wreaking havoc in this world of flames.

The Fire Spirit had no intelligence. It did not sense the dangerous aura emitted by Zi Chen. After letting out a roar, it rushed towards Zi Chen in a straight line.

Zi Chen, who had finished accumulating power, had a murderous look in his eyes. He turned into a two-colored light and rushed towards the Fire Spirit with his spear.

The spear suddenly swept out and a thunder dragon rushed out from the Dragon Soul Spear. This thunder dragon was half gold and half silver. The two opposite energies were circulating under the control of Zi Chen's spiritual sense. Just as the thunder dragon was about to hit the Fire Spirit, the circulation suddenly became chaotic. Then, the Yin and Yang energies collided and the thunder dragon exploded.

"Boom!"

The collision of extreme energies directly exploded, and a boundless aura of destruction engulfed the Fire Spirit.

Facing the destructive aura produced by the collision of the two extreme energies, the Fire Spirit didn't even have time to scream before its huge body was torn to shreds by the two energies.

In the sky, the rootless flames surged and slowly dissipated. A fist-sized fire crystal fell from the dissipating flames.

Zi Chen's eyes were sharp and his hands were quick. He grabbed the Flame Crystal Stone. This was the energy core of the Fire Spirit Solidification.

The function of the Flame Crystal Stone was almost the same as the Thunder Crystal. It could be used to refine artifacts, but it could also be used for cultivation. The Thunder Crystal contained a bolt of lightning, while the Flame Crystal Stone contained a ball of flame. Because this area was special, the Flame Crystal Stone had formed a Fire Spirit.

Zi Chen held the Flame Crystal in his left hand, while the Dragon Soul Spear in his right hand trembled, as if it was extremely eager to obtain the Flame Crystal.

Zi Chen threw out the Flame Crystal Stone, and at the same time used the Dragon Soul Spear to touch it. The Flame Crystal Stone shattered, and the Flame Essence within was instantly absorbed by the Dragon Soul.

To kill a powerful Fire Spirit, Zi Chen had consumed a great deal of energy. In this world of flames, he hadn't even gone a third of the way in. Naturally, the Fire Spirits in the depths were much more powerful. If he encountered one or two, Zi Chen could still deal with them. But if there were too many of them, Zi Chen would naturally be no match for them.

Therefore, wanting to enter the depths and find an exit was obviously unrealistic.

After killing the Fire Spirit, Zi Chen decisively retreated. During this time, the Dragon Soul Spear's Dragon Soul needed to fuse with the Flame Essence it had swallowed, and Zi Chen also needed to restore the energy he had consumed.

This time, he swallowed an ordinary Blood Essence Pill and then sat down cross-legged in meditation. He relied on the Blood Essence Pill's energy as well as the surrounding fire energy to slowly restore the origin energy he had consumed.

The ancient road had a total of 36 paths, and Zi Chen had only reached the second one. Therefore, he had to save as many resources as he could.

Moreover, this road of smelting trial wasn't something that could be completed in a day or two. From the moment he stepped onto the road of smelting trial, Zi Chen was no longer able to judge the flow of time.

Stepping onto the road of smelting trial was destined to be an extremely long journey. Only by smoothly passing through it would one know how much time had passed. But once one died, there was no need to calculate the time.

After restoring the energy within his body, Zi Chen took the Dragon Soul Spear and continued to go deeper. He didn't stop until he encountered a Fire Spirit that blocked his path.

At this time, Zi Chen didn't even place an ordinary Fire Spirit in his eyes. If there was something that could stop him, then it must be an existence as large and powerful as a mountain peak.

Seeing a Fire Spirit, Zi Chen launched an attack. His attack was decisive and direct. Two types of extreme energies were released, and the gold and silver thunder dragons appeared once again. Then, the Fire Spirit was easily killed. After the Fire Spirit was killed, the fist-sized flame crystal left behind was swallowed up by the Dragon Soul.

Zi Chen didn't consume too much of his energy to kill the Fire Spirit with a single strike. Killing another Fire Spirit wasn't a problem. But on the ancient road, there could be dangers at any time. Therefore, maintaining vigilance at all times and ensuring one's combat strength was the most important thing.

After Zi Chen killed the Fire Spirit, he no longer took any risks and retreated.

Next, it was time for him to restore his energy as well as for the Dragon Soul to refine the Flame Essence. This time was far longer than the time Zi Chen took to kill the Fire Spirit.

After Zi Chen's origin energy was slowly restored to its peak, Zi Chen stood up. He took the Dragon Soul Spear and continued to move forwards, killing the mountain-like Fire Spirit.

Here, time couldn't be accurately estimated. Therefore, Zi Chen used the number of times he consumed energy.

During the first and second times, Zi Chen killed a Fire Spirit each time.

During the third time, when he consumed 25% of his energy, Zi Chen killed two powerful Fire Spirits. Then, he retreated and continued to restore his energy. The fourth time was the same. But during the fifth time, Zi Chen only consumed half of his origin energy to kill two Fire Spirits.

Zi Chen only needed one strike to kill a Fire Spirit. But in a situation where he didn't take any pills, if Zi Chen wanted to use the flame energy to restore his origin energy, then according to Zi Chen's estimate, it would take at least five days.

Killing an enemy only took two breaths of time, but recovering took five days. Such a huge difference in time was enough to show just how slow Zi Chen's efficiency in killing his enemies was.

As time passed, he consumed and restored his energy again and again. As time passed, Zi Chen's combat strength gradually increased. At the same time, his boundary also slowly increased.

After the tenth time of consumption and recovery, half of the energy in Zi Chen's body was already enough to kill three Fire Spirits. Every time Zi Chen killed a Fire Spirit, he would keep half of his origin energy in his body.

As he went deeper, the number of Fire Spirits he killed also increased. Zi Chen sensed an extremely powerful existence in the depths. When he sensed the other party's aura, a sense of danger rose in Zi Chen's heart. He guessed that the other party should be a real fire spirit, an existence comparable to a thunder spirit.

After carefully waiting for a few days while maintaining his peak combat strength, Zi Chen didn't wait for the other party to take the initiative to attack. Moreover, the dangerous aura was intermittent, sometimes strong and sometimes weak. It was extremely unstable. Zi Chen would definitely avoid the other party first.

Therefore, after going deep to an extreme distance, Zi Chen used this extreme distance as a starting point and began to make a detour. He wanted to go around this extremely powerful existence and kill the other Fire Spirits around him.

Because he could sense this existence, Zi Chen was even more careful when he killed the Fire Spirits. Moreover, he always left behind his spiritual sense to detect the other party's movements.

After the fifteenth time of consumption, half of Zi Chen's origin energy was enough to kill four Fire Spirits. Zi Chen had a feeling that this number would soon increase.

Sure enough, after the seventeenth time, Zi Chen was able to kill five Fire Spirits.

Although Zi Chen's strength had increased, the Dragon Soul Spear was even more important. After absorbing so many Flame Essences, the Dragon Soul Spear's power had increased, and its killing power towards the Fire Spirits had also increased.

Zi Chen slowly stepped forwards, constantly killing the mountain-like Fire Spirits, constantly nibbling away at them. During this time, the fire spirit still hadn't appeared.

Zi Chen's intention was to kill all the Fire Spirits and then deal with the fire spirit.

During this time, Zi Chen hadn't found a passage in the outer regions. He thought that it should be deep inside. If he wanted to enter the third ancient road, he would have to kill this existence.

There were simply too many Fire Spirits around the strongest existence. After Zi Chen restored himself for the twentieth time, he still hadn't finished killing them all. Moreover, as the number of Fire Spirits decreased, the tyrannical aura released by the fire spirit became increasingly terrifying.

These days, the other party hadn't attacked. Zi Chen guessed that it should be in a state of deep slumber. As the king of this world of flames, it should have some sort of spiritual sense connection with the other Fire Spirits. As the number of Fire Spirits decreased, the king must have sensed it and gradually awakened.

By the time Zi Chen recovered for the thirtieth time, the number of Fire Spirits in the mountain had drastically decreased. After devouring a large number of Fire Crystals, the Dragon Soul Spear had finally transformed. Its lethality towards the Fire Spirits had also increased by several times. Zi Chen's slaughter of the Fire Spirits had finally reached an extremely simple and effortless level.

The existence in the dark seemed to have completely awakened. In these two days, Zi Chen felt a murderous intent locking onto him through the world of flames.

This was the world of flames, and the other party was the king of flames. It might not be able to sense the situation here when it was asleep, but now that it was awake, it naturally knew what was happening here. Moreover, Zi Chen's every move was under its observation.

The reason why the fire spirit didn't take the initiative to attack was that it was extremely wary of this human trial taker. In these two days, it had been observing the other party, wanting to see through the other party's attack methods and then kill him.

Of course, the main reason was to wait. It was waiting for all the Fire Spirits to die.

Due to the rules here, only when all the Fire Spirits died could it, the king, truly awaken and display its strongest combat power.

"Foolish human, you are courting death." A cruel laughter sounded from the depths.

At this time, Zi Chen had killed the last Fire Spirit. After cautiously retreating and restoring the energy in his body to its peak state, Zi Chen walked into the depths of the world of flames with his spear.

"Human, die."
