As for the layout of this underground ruin, although the peak has not been fully reached, he knows almost everything.

It is a castle that can accommodate tens of thousands of people, and it is mainly divided into the outer city and the inner city, and the peak was used in the outer city area, and now it stands at the foot of the inner city wall.

The outer city belonged to the residential area, and the inner city was supposed to be the residence of the lord of the city.

The best thing in this castle is definitely hidden in the inner city.

What's more, the strongest death fluctuations also emanated from the inner city, and those undead did not dare to take a step closer to the inner city.

Everything indicates that there is a huge secret hidden in the inner city.

Gao Feng missed his phantom beast very much at this time, if there was a black eagle or a little black dog at this time, whether it was a black eagle or a little black dog, he could see the situation in the castle clearly, and he could provide more information for Gao Feng.

It's just a pity that the three phantom beasts are still in the process of evolving, and it will take a lot of time for them to complete their evolution.

This time, the evolution of phantom beasts took more time than usual, and I believe that after they have evolved, they will also gain greater abilities, and Gao Feng is already looking forward to this.

The phantom beast couldn't count on it at this time, so it could only rely on itself.

Gao Feng's body moved, jumped on the top of the castle with a slight jump, and then looked condescendingly towards the castle.

This is a small castle, many buildings have collapsed, and the tower in the center of the castle is the most striking location, and the strong breath of death also spreads from this tower.

Standing at the head of the city, Gao Feng found that the range of his heart and eyes was lower, and he was suppressed to within ten meters, and his telekinesis could not be released from his body at all.

At this point, the eyes of the heart become useless, and the most useful thing is the eyes of oneself.

Gao Feng looked around cautiously. Determine if there is a danger in the vicinity.

For Gao Feng, who is accustomed to mental power and mental eyes, it is very uncomfortable to use the naked eye to see the surrounding terrain and dangers.

Suddenly, Gao Feng had a sense of danger, and he immediately rolled to one side following his instincts, just as Gao Feng left. A pillar of miserable white light shot out from where Gao Feng had just stood.

Although Gao Feng moved extremely fast, he was still rubbed by the edge of the pillar of light, and with a click, the magic shield in Gao Feng's body was pulled out of a long crack, and a sharp light color light slashed across Gao Feng's arm along the cracked gap.

With a slight sound, the armor on his arm was cut by the white light, and Gao Feng's arm was also cut out of the wound.

Gao Feng didn't have time to feel the power of this white light, and his body moved. Immediately fell outside the city wall, and fell from the top of the city to the outside of the city in an instant.

At this moment, a black shadow roared, falling from the sky and stepping on the place where the peak was standing just now, and the solid city wall was immediately torn apart when he stepped on it, and the green bricks were shattered like spider webs.

The peak fell under the city wall and quickly retreated, but the corner of his eye looked towards the dark shadow.

It is a tall zombie in black armor. With a spear in his hand, he looked at Gao Feng coldly.

But it's weird. When Gao Feng left the city wall, he did not attack, but just glanced at Gao Feng coldly, then turned and left, and entered the dark and dangerous castle again.

Gao Feng took a clear breath and looked down at the wound on his arm. The gaze is solemn.

The attack just now was really powerful, and if he hadn't dodged it in time, even if he didn't die, he would definitely be seriously injured.

And the zombie with the gun later is also extremely powerful. Being entangled in close quarters by it, there is definitely no good fruit of its own to eat.

It turns out that the truly powerful undead are in this castle.

Gao Feng glanced down at his injury, and the flesh of the wound began to turn white, and black blood flowed out.

This is corrosive damage, the specialty of dark attacks, after being attacked, the wound will be invaded by dark power, which will accelerate the decay and bleed.

In severe cases, it will cause poisoning of the whole body, and this small wound can kill a person.

Gao Feng took out the light healing potion and sprinkled it on the wound, and then took another bottle of healing potion orally.

The healing potion was sprinkled on the wound, and the wound immediately squeaked, and a cloud of black smoke came out, Gao Feng frowned, and felt a stinging pain in the wound, but this stinging pain quickly disappeared, the flesh at the wound turned bright red, and the wound began to heal.

Gao Feng himself also cast a water healing magic on the wound to speed up the recovery of the wound.

After a short time, Gao Feng's injuries recovered completely.

Looking at the castle in front of him, Gao Feng frowned deeply.

This castle is not as simple as it seems, the attack just now is extremely powerful, at least an attack from a four-star undead, or even a five-star undead.

The zombie with the gun, although Gao Feng didn't see him make a move, but it also gave Gao Feng a very powerful and dangerous feeling, and his strength might not be lower than that of a five-star.

The undead in this castle are undoubtedly very powerful and dangerous, do you want to move on?

In fact, even if it is a five-star undead, the peak is not invincible, because the strength of the undead is generally low among the same level.

The biggest problem, on the contrary, is that after entering the castle area, the heart's eye and telepathy are severely suppressed, and the heart's eye loses the ability to observe the surroundings, relying only on the eye, and many times it does not notice the danger coming.

This is quite unfavorable for Gao Feng, and Gao Feng's combat effectiveness cannot be brought into play as a result.

If it was just a head-on battle, Gao Feng was really not afraid of these undead, but in the current environment, Gao Feng did not have the confidence to defeat them.

Gao Feng thought about it and decided that he was not in a hurry to enter the castle, and he could improve his strength here first.

Thinking of this, Gao Feng arranged a few simple warning items around, and he was relieved to use the golden hourglass to expand the time barrier and improve his strength.

Although this castle is full of zombie undead, this place is the passage between the inner city and the outer city, and all the undead will not come here, the inside will not come out, and the outside will not come in, but it is the safest place.

The peak is here, unfolding the time barrier and absorbing the three-star mutant core.

That's the power of the Mutant Core, as long as there are enough Mutant Cores. You can elevate yourself to a higher level in a short period of time.

Gao Feng felt that his strength was enough to deal with it, so he didn't absorb the mutant demon core for the time being, but at this time, he felt that his strength was still not enough, so he decisively chose to absorb the mutant demon core, so as to improve his strength.

The absorption of the mutant demon core also takes time. It would take at least a whole day to absorb a three-star mutant demon core, but the power of this mutant demon core would be worth several months of cultivation results, and it would naturally be very worthwhile to exchange one day for several months of cultivation success.

It's just that in the time barrier, Gao Feng doesn't have to worry about time at all, and a day can be used as a hundred days, under this barrier. A few days is enough time for hundreds of mutant demon cores to be absorbed.

And Gao Feng still has enough three-star mutant demon cores on hand, he doesn't have to worry about the number of mutant demon cores, enough for him to be promoted to the four-star realm.

Gao Feng absorbed the mutant demon cores one by one, and his own strength became stronger and stronger, and he was soon promoted from the early stage of the three-star to the middle of the three-star stage, and then from the middle of the three-star to the late stage of the three-star stage, and a few days later, the peak was promoted to the peak realm of the three-star level.

In this realm. As long as Gao Feng wants, go back to the fortress. You can be promoted to a four-star level at any time.

From the early stage of the three-star to the peak realm of the three-star, Gao Feng's strength has increased several times, and with his current strength, he is not afraid of facing the five-star undead.

Gao Feng took out the origin power he had obtained before to absorb it, but Gao Feng found out. The speed at which he absorbed the Origin Power was still not fast enough, and with his current strength, it would take at least a few decades to absorb a piece of Origin Power, even if there was a golden hourglass time enchantment. It will also take months.

The absorption of origin power is not so easy, Gao Feng estimates that it will be more convenient and faster for him to absorb the two pieces of origin power at hand after entering the four-star level.

The matter of the Origin Power can only be put aside for the time being, and for now, let's take a look at what secrets are hidden in this castle.

The realm has been raised, Gao Feng glanced towards the city wall, his body flashed with fire, and a pair of flame wings appeared behind him, and then a flame surrounded his body, forming a flame shield.

The flame wings moved, and the peak suddenly flew to the city wall.

As soon as he stood on the city wall, Gao Feng's body immediately emitted light, and the light flashed, turning into more than ten blue phantoms, standing on the city wall, and Gao Feng's true body was hidden in one of the phantoms.

This is a water-based magic water shadow spell that can create phantasm clones and confuse enemies.

Gao Feng paid great attention to the undead in these castles and had to deal with them with all his might, so the magic of the rest of the department began to be used.

In order to exercise his combat ability, in the previous battles, Gao Feng had always used only a single series of magic against the enemy, but now the opponent is strong, so Gao Feng began to mix all kinds of magic.

More than a dozen phantoms began to move forward under the control of Gao Feng.

At this moment, a black shadow slammed into one of the phantoms, and with a snap, the phantom was shattered and disappeared into light chips.

The shadow was a tall zombie, and the zombie froze for a moment, then attacked the rest of the phantoms, each blow submerging a single phantom.

At this moment, one of them needed to emit a light, the light was glazed white, and it looked cold and devoid of any fire, but the light fell on the body of the zombie, and the zombie immediately emitted black gas to resist, and the two sides collided, making a squeaky sound, and the black light was instantly dissolved, but the zombie also quickly dispersed, but his speed was still a step slower, and half of his body was hit by the white light.

Under the white light, the zombie's body quickly vaporized and disappeared like a snowflake meeting a soldering iron.

The zombie who had lost half of his body let out a roar of anger and was about to rush towards this phantom, but he only took three steps forward, and a large amount of white light emerged from the wound, and the white light invaded from the wound and had destroyed his body, and in an instant, the other half of his body also dissipated.
