After leaving the mine, Zhang Yuan ran wildly all the way, not because he was afraid that someone would chase him, but because he wanted to enter the immortal city as soon as possible so that he could buy elixir to help Zhang Bao heal his injuries.

Because of the great progress of cultivation, Zhang Yuan's flight speed is extremely fast, and he is not much more than the general Yuan Shen Great Perfection.

After locking the direction, Zhang Yuan let the Yinfeng Sword fly on its own, and he himself began to study the essence of the divine stone obtained from the mine.

"Ordinary divine stones can block the invasion of divine consciousness, so the essence of this divine stone should be more than that!" After thinking of this, Zhang Yuan began to groan, thinking about how to use the essence of this divine stone.

"I don't know if the Heavenly Medicine Ding can refine the weapon?" After thinking of this, Zhang Yuan took out a bunch of ordinary divine stones from the space ring and put them into the Heavenly Medicine Ding.

"Up!" After putting the Divine Stone into the Heavenly Medicine Ding, Zhang Yuanning condensed his divine sense, carefully conveyed spiritual power, and began to refine the Divine Stone.

After a moment, Zhang Yuan frowned, because the divine stone in the Heavenly Medicine Ding had not changed in the slightest.

"Try it with a high-grade spirit stone!" In desperation, Zhang Yuan took ten high-grade spirit stones from gold, wood, water, fire, and earth.

"Up!"

After Zhang Yuan arranged a simple spirit gathering array, he activated the formation and input the spiritual energy in the high-grade spirit stone into the Heavenly Medicine Ding, if someone saw Zhang Yuan wasting high-grade spirit stones like this, he was afraid that he would be angry to death, even if he was an ordinary immortal sect elder, he couldn't take out so many high-grade spirit stones, Zhang Yuan was because he took advantage of it and got thousands of years of spirit stone accumulation from others.

After another moment, the divine stone in the Heavenly Medicine Ding began to melt, and after a while, the granular divine stone completely melted into an emerald-colored liquid.

"How do you get rid of impurities?" At this moment, Zhang Yuan realized that he didn't know how to refine ore at all, because he was busy cultivating before, and he was a casual cultivator, so he didn't have time or opportunity to come into contact with refining knowledge.

Just as Zhang Yuan frowned, a layer of fine black impurities appeared above the Heavenly Medicine Ding.

"This guy is too rebellious, isn't he?" Seeing that Tianyao Ding could automatically eliminate impurities, Zhang Yuan was really surprised in his heart.

"Go!" Zhang Yuan carefully controlled the impurities on the Tianyao Ding, for fear that the impurities would fall back a little.

After a while, Zhang Yuan eliminated the impurities, and after the impurities were gone, the liquid in the Heavenly Medicine Ding turned into a colorless and transparent liquid.

"Condensation!" Zhang Yuan controlled the Spirit Gathering Array, reduced the output of spiritual energy, and began to cool down the mineral liquid.

"What shape should it be condensed into?" Zhang Yuan pondered for a moment, thinking that the Divine Stone had the special effect of blocking the Divine Sense, but for physical attacks, although it could also be resisted, it was not a strong point after all, so the refining equipment could only be used to trap or attack and kill things that had no substance in the Divine Soul category.

After figuring it out, Zhang Yuan decided to refine a box-shaped box.

After a while, a colorless and transparent cube box appeared on Zhang Yuan's medicine pod.

"It's a pity, if only I could refine weapons, so that I can arrange a few formations to attack and kill and lock the soul on this!" After thinking of this, Zhang Yuan shook his head with some regret.

At the moment when Zhang Yuan took the box out of the Heavenly Medicine Ding, thunder sounded in the sky again.

"Isn't it? I'm just refining a rag with no rank, and I actually caused a thunderstorm! After seeing the dark clouds in the sky, Zhang Yuan was speechless for a while.

However, speechless to speechless, Zhang Yuan still didn't dare to be careless, his eldest brother was still not as strong as a mortal, therefore, Zhang Yuan ignored the thunder tribulation in the sky, but controlled the Yinfeng Sword and sent Zhang Bao out in the direction of Xiancheng, fortunately, Zhang Yuan's divine sense was strong, even if Zhang Bao arrived in Xiancheng, Zhang Yuan could still control the Yinfeng Sword and still protect Zhang Bao.

After sending Zhang Bao away, Zhang Yuan began to pay attention to the thunder tribulation in the sky.

"Huh?" Just when Zhang Yuan was about to resist the thunderstorm, an old man drove a dark red fairy sword and flew towards Zhang Yuan quickly, but after seeing the thunderstorm in the sky, the old man stopped at the place where the thunderstorm was found, and he didn't want to be affected by the thunderstorm.

"Could it be that someone has broken through to the realm of immortals?" The old man looked at the thunder tribulation in the sky, frowned, and wanted to leave several times, but stopped again, his face was cloudy, it seemed that the old man wanted to do something, but he had concerns.

In fact, the old man wanted to kill Zhang Yuan, but he was afraid that Zhang Yuan would be strong and strong after surviving the thunder tribulation, so he would not be able to please him, but if he didn't kill Zhang Yuan, Zhang Yuan would inevitably threaten him and his sect status.

"On my territory, no second immortal is allowed to appear, besides, this guy is most likely the murderer of my disciple!" After figuring it out, a trace of cruelty flashed across the old man's face.

Zhang Yuan didn't know that the thunder tribulation caused by the cube box was misunderstood by the old man as an immortal tribulation.

This old man is the Taizu of the Immortal Gate behind the mine, one of the cultivators at the tip of the pyramid of the cultivation realm, and has entered the realm of immortals, although he has just entered the realm of immortals, but he is also an immortal, and there is an essential difference from the Yuan Shen cultivators, because the power in their bodies is no longer spiritual power, but immortal power.

"Who's that lewd old man over there?" Zhang Yuan's divine sense is very strong, the old man has already entered his exploration range, originally, Zhang Yuan did not pay too much attention to this person, but after seeing this person standing still in the distance, Zhang Yuan began to be vigilant.

At this time, the first thunder punishment from heaven also came.

It was the first time Zhang Yuan saw the artifact robbery, and he didn't know how to get it, and he didn't even know if he should let the cube box cross the catastrophe by himself, but after thinking about it for a while, Zhang Yuan still decided to help the cube box survive the catastrophe.

Because after Zhang Yuan had the Void Realm, he had no fear of the Thunder Tribulation. Immediately, Zhang Yuan stood straight in the air, letting the thunder punishment bombard him.

The thunder and lightning crackled on Zhang Yuan's body, but Zhang Yuan only felt a little numb, and there was no harm at all.

At this time, Zhang Yuan's divine sense was completely placed on the Yinfeng Sword, and he wanted to send Zhang Bao into the Immortal City as soon as possible, especially after seeing the ill intentions of the old man in the distance, Zhang Yuan once again accelerated the speed of the Yinfeng Sword.

"That kid is stupid, isn't he? Standing upright under the thunder punishment, he thought he was a god? The old man was immediately happy when he saw Zhang Yuan's hard resistance to the thunder robbery.

"What's going on?" Zhang Yuan found that after this bombardment came down, Zhang Yuan's Void Realm did not break the crack, and the Thunder Punishment smoothly attacked into the Void Realm, splitting part of the chaotic area violently, so that this Thunder Tribulation was not like an enemy attacking Zhang Yuan, but like a friend who helped Zhang Yuan open up the wasteland.

"Click, Click, Click......"

The second thunder punishment came again, and this time, as soon as the thunder punishment entered Zhang Yuan's void realm, the immortal seed villain began to act.

I saw that the immortal seed villain quickly gestured his hands and played tens of thousands of magic decisions, and he simply gathered the scattered thunder punishments together, and after the lightning punishments were concentrated together, the power suddenly increased countless times, and he actually split a crack in the void world again.

After the Void was broken, countless milky white gases flew in.

"This guy is weird!" After the old man saw that Zhang Yuan had resisted two thunder punishments without a trace of damage, he suddenly had a bad feeling, and immediately, the old man took a swarthy flying sword from the space ring and looked at Zhang Yuan with a smug face.

The black sword in the old man's hand is a surname fairy sword, this kind of one-time surname fairy sword has all the attack power and strength of a fairy sword, but it is a surname, and because this fairy sword is a surname, it can explode, and its power is only much greater than that of ordinary fairy swords. However, because the refining of the fairy sword is too difficult, and the materials required to refine the surname fairy sword are similar to the ordinary fairy sword, compared with the ordinary fairy sword, the surname fairy sword is to have the advantage of attacking and killing the enemy without implicating the master, because after the ordinary fairy sword is damaged, the owner of the fairy sword will be counterattacked, which is very dangerous, the light is seriously injured, and the heavy is killed, therefore, a line fairy sword still has an advantage, however, because it is too luxurious, it is very rare, and it can only be found occasionally in ancient ruins.

The old man's actions naturally did not escape Zhang Yuan's eyes, and after seeing that the old man was going to do something to himself, Zhang Yuan scolded secretly, and at the same time, a bad idea also came to his heart.

"Haha, although I lost a one-time surname fairy sword, but I killed a strong enemy, and I can avoid the impact of thunder, it's worth it!" After thinking of this, the old man's face did not look like it had before.

"Go!" The old man controlled the flying sword, pinched a magic decision, and launched the black sword.

The speed of the black sword was extremely fast, and it arrived in front of Zhang Yuan almost the moment the old man launched it.

"His uncle, he dares to scare me, if I don't pull you into the thunder tribulation, wouldn't I be sorry for me?" Immediately, Zhang Yuan sacrificed the Demon Sword, preparing to block the black sword, and at the same time quickly flew towards the old man, preparing to let the old man suffer a lightning punishment.

Although the old man is an immortal, but after being identified by the thunder punishment as the person who helped Zhang Yuan cheat, the thunder punishment will increase the punishment according to his cultivation, therefore, the thunder punishment suffered by the old man will only be higher than the immortal tribulation, and whether he can survive it is still two words.
