With this punch, Mu Feng's face also became a little pale, and this punch exhausted nine out of ten of the mysterious power in his body.

"Boom!"

Mu Feng's iron fist slammed into the black iron golem's chest, making a dull sound, and the black iron golem flew out upside down, countless iron filings flew everywhere, most of which were burned into nothingness by Devouring Heart Flame.

Although the black essence iron puppet has a hard body, and its strength has reached the early stage of the Great Perfection of the Formation Realm, its adaptability is extremely poor, and it is difficult to dodge Mu Feng's attack under Mu Feng's mysterious footwork of Nine Shadows.

After the black essence iron puppet landed, it still slid on the ground for more than ten zhang, and countless sparks burst out, if a martial artist in the early stage of the Great Perfection of the Formation Realm received this blow, he would definitely die.

However, Mu Feng did not relax because of this, he knew that the vitality of the Black Spirit Iron Puppet was extremely tenacious, and although the blow just now had severely damaged the latter, it had not completely destroyed it.

Sure enough, the black iron golem stood up again, and a hole the size of a bowl appeared in its chest. The puppet's body was really hard, and under such a powerful blow, it only showed some injuries.

However, Mu Feng still noticed that the aura on the black iron puppet was a little sluggish.

Take advantage of its illness and kill it!

Mu Feng would never give the Black Iron Golem any respite.

"Flame Fist, Flame Dragon Devouring Everything!"

With a punch, the sound of a dragon's groan was faintly heard, and a dragon-shaped Xuanli roared out, with some speckled black flames, and blasted towards the hole in the black iron puppet's chest.

The black iron puppet took a big step forward, and his body suddenly burst out with a powerful aura, and he threw a punch. It slammed into the Xuanli Training.

"Boom, boom!"

The sound of explosions like thunder kept ringing, and the iron arm of the black iron puppet suddenly exploded into pieces under the impact of Xuan Li's training. Xuanli Pi Lian also directly penetrated the hole in the black iron puppet's chest, and hit a stone wall behind him.

"Flame Fist. The Flame Burns the Sky!"

Mu Feng didn't give the Black Essence Iron Puppet any respite, his fists danced, and he attacked the Black Essence Iron Puppet with the subtlety of the Nine Shadows.

The fiery Xuan Force was mixed with Devouring Heart Inflammation, causing the Black Essence Iron Puppet to be continuously injured, and under Mu Feng's continuous bombardment, it was covered with scars, and finally fell to the ground with a "boom", completely scrapped.

"Whew!"

As the black iron puppet fell to the ground, Mu Feng half-squatted on the ground. Gasping for air, this battle was also extremely draining on him.

A subtle golden light gradually emerged from the black iron golem's body.

After the golden light gradually emerged from the black iron golem's body, the luster quickly became dim, and there were signs of disappearing.

Looking at that golden light, Mu Feng's eyes lit up, and as soon as his body moved, he rushed towards that golden light.

Mu Feng grabbed it with one hand, and the golden light melted into Mu Feng's body from his palm, rushing straight to his mind. Mu Feng suddenly felt a tingling pain. Suddenly, my mind was full of gold, and some vague scenes appeared in front of me.

His behavior was too reckless, and if that trace of primordial spirit was too strong, it would cause irreparable damage to his mind. Even fatal!

Fortunately, under the erosion of the years, the trace of Yuan Shen has become extremely weak, which has not caused any impact in Mu Feng's mind.

But it is precisely because the trace of the primordial spirit is too thin. The memories Mu Feng obtained from it were vague and did not get a lot of effective information from them.

However, there is a picture that impresses Mu Feng quite deeply. In that picture, there are young men and women fleeing in a panic, followed by dozens of men in black in hot pursuit.

The cultivation of young men and women and dozens of black-clothed people is also incomprehensible. But he could feel that their cultivation did not seem to be weaker than the gray-clothed old man he had encountered during his training in the Luoxia Mountains.

Thinking of this, Mu Feng was taken aback, these people had all reached the Divine Power Realm, especially this pair of young men and women, it seemed that they were only around twenty, and they had also reached that level?

Mu Feng's mind calmed down, and he began to look for the map of the entire Xuanling Underground Temple, and the memory of the Yuan Shen also had the map of the entire Xuanling Underground Temple, but most of it was blurry, and Mu Feng couldn't distinguish his current location.

"Alas!" Mu Feng sighed, feeling annoyed in his heart, he finally defeated the Black Essence Iron Golem, but he didn't get something useful, how could it not be frustrating!

Mu Fengpan sat down, took out a Xuanli Pill, rolled his tongue, and swallowed it into his abdomen, and the Yanyang Hegemony Technique immediately started to operate, refining the Xuanli energy contained in it.

After a while, Mu Feng also returned to his peak state.

"Forget it, I'd better go find Sister Hanyu and them. Mu Feng said to himself, got up and rushed towards the other end of the passage.

Now he doesn't know where Mu Hanyu, Mu Hanqing and others are, so he can only look for them along the way. However, before they set off, they had agreed on a specific contact mark, and if they found it, they could find their whereabouts.

While walking, Mu Feng observed the existence of this kind of contact mark all the way. The passage was particularly long, and he hurried for half an hour before he saw the end.

At the end of the passage was a wide place, and there were many corpses lying on the ground, all of which had been violently bombarded, and the death was extremely terrifying. However, there was no younger generation of the Mu clan among them, which made Mu Feng also breathe a sigh of relief.

"These people must have been killed by that black iron golem just now. Mu Feng guessed in his heart.

On the other side of the wide area, there are several passages. However, Mu Feng did not see the contact mark unique to the Mu clan.

Mu Feng casually found a passage, and when he was about to enter, he suddenly felt a sharp pain in his brain, and a picture flashed in front of him, and that picture showed this passage.

Mu Feng stopped, came to a certain stone wall, gently slid over the stone wall with his palm, and suddenly felt a loosening and secretly exerted force.

"Click!"

At this time, Mu Feng's feet suddenly emptied, and he fell down before he could react.

Mu Feng was in danger, condensed the dantian, and slowed down his decline.

But fortunately, this trap is not very high, at most more than thirty zhang, Mu Feng finally fell steadily to the ground.

However, as soon as he landed, he heard countless wind-breaking sounds, and countless cold lights suddenly flashed from the darkness, shooting towards Mu Feng.

Mu Feng stepped violently, and his body spun in the air again, and as his mind moved, the Devouring Heart Flame also broke out of his body, enveloping the entire body into it.

Most of the cold light was flashed by Mu Feng, and a small part of the cold light burst out on the Devouring Heart Flame, and was instantly burned into nothingness.

When he landed again, Mu Feng realized that these cold lights were all blades shooting from the surrounding stone walls. If there is no protection from devouring heart, Mu Feng estimates that he will definitely be shot into a hornet's nest.

Looking up at the entrance that slowly closed overhead, Mu Feng also cut off the original idea of returning, and looked around curiously.

I saw a straight passage leading into the distance, and on both sides of the passage were some stone chambers. These chambers are made of the same black rock seen before, and are extremely sturdy.

Mu Feng came to the nearest stone room, carefully pushed open the stone door, and condensed the Xuan power in his palm, ready to deal with unexpected situations.

Mu Feng felt that there was a faint layer of energy fluctuations above the stone doors of these stone chambers, but this energy fluctuation was extremely weak and almost negligible. This should also be some energy seals, but as the years go by, these energy seals have almost disappeared.

The unexpected situation did not happen, and the stone door creaked open, but to Mu Feng's disappointment, the stone room was empty. Looking at the dust on the ground, it is not that someone has arrived in advance, but that there is nothing in the first place.

Mu Feng opened three or four stone chambers one after another, all of them were empty, and the thick dust on the ground of the stone chamber showed that these were originally empty stone chambers.

"Damn, flirtant!" Mu Feng couldn't help but burst into a foul mouth.

Walking forward along the passage, Mu Feng opened the stone chambers on both sides one by one, but there was still no gain.

Having come to the end of the passage, there was only a stone room left in Zuihou, Mu Feng took a deep breath and slowly pushed open the stone door.

The stone gate did not move at all, and there were bursts of rebound from the stone gate, which shook Mu Feng's entire arm a little sore.

Mu Feng knew that this was the remnant energy seal doing something wrong, so he slammed his palm on the stone gate.

The remaining energy seal on the stone gate was not very strong due to the erosion of time, and Mu Feng blasted the stone gate open with one palm.

The scene that appeared made Mu Feng also gasp, only to see a skeleton appear in a stone room in Zuihou, the skeleton was sitting cross-legged, but Mu Feng carefully inspected it and found that the skeleton's leg bones were broken.

Judging from the aura emanating from the skeleton, it should have been a strong person who was not weak in his lifetime, and he might even be a powerhouse in the Divine Power Realm.

"Are these stone chambers all dungeons?" Mu Feng suddenly had an idea in his heart.

"Shhh

Mu Feng himself was frightened by this idea! Who is the owner of this Xuanling Underground Temple, who actually has such ability, not only has built such a huge underground palace, but also has a puppet that was once comparable to the powerhouse of the Divine Power Realm, and now he has discovered the mysterious dungeon where the powerhouse of the Divine Power Realm is imprisoned.

If every stone chamber held a Divine Ability Realm powerhouse, how terrifying it would be!

Mu Feng turned his head and looked at the passage he had walked, there were at least hundreds of stone chambers along the way.

Mu Feng is also becoming more and more curious about the identity of the owner of this Xuanling Temple. If your guess is true, then there have been hundreds of Divine Ability Realm powerhouses imprisoned here.

If this spreads, it will definitely shock the entire Dawu Dynasty. Because of the entire Dawu Dynasty, the number of powerhouses in the Divine Power Realm did not exceed ten fingers.

At the end of the passage, a semicircular stone door appeared.

"Crunch!"

The stone door slowly pushed open, and Mu Feng looked at the scene in front of him, and a strong look of shock appeared in his eyes. (To be continued......)
