Glancing at the two tall figures not far away, Xu Feng's heart was cold, this time it was only a few seconds away from death, once he walked seven or eight meters forward, he would touch the warning range of the undead guards, and at that time, he who fell into the illusion would be killed if he didn't have the strength to fight back at all.

"After I entered the illusion, I only walked less than ten meters before I broke free, and as a result, I only added two spiritual attributes." Li Jin stepped forward and whispered, "You have been in the illusion realm for so long, and your spiritual attributes have increased a lot."

Xu Feng nodded, did not speak, for these ten spiritual attributes, almost died, Xu Feng did not feel that there was anything remarkable.

"Okay, you calm down first, I'll go in first and wait for you inside." After speaking, Li Jin entered a state of stealth and touched forward.

When he was still ten meters away from the two undead guards, Li Jin picked up a small pebble, raised his right hand, and a white light wrapped the pebble and smashed it towards the rock wall on the left.

With a snap, the attention of the two undead guards involuntarily looked towards the place where the stone sounded.

Then, the undead guard quickly ran in that direction to check.

A white light emerged from Li Jin's feet, and he ran towards the gate of the ancient castle, and when he ran, an afterimage was pulled out behind him.

The two undead guards didn't notice anything, turned their heads and stood back again, and at this time, Li Jin's figure had disappeared at the gate of the ancient castle.

These two undead creatures are humanoid creatures, nearly three meters tall, wearing a white bone armor on their bodies, their masks are down, and they can't see their faces clearly, and they can only vaguely see two dark green ghost fires burning.

Nearly a meter long bone spurs stretched outwards from the shoulders and elbows of the undead guards, shimmering with the cold light of metal, one holding a heavy halberd and the other holding a two-handed axe, guarding both sides of the castle gate like door gods.

Xu Feng had already figured out how to enter the ancient castle on the way, and his method was the same as Li Jin's, he was ready to attract the attention of the undead guards first, and then take the opportunity to sneak in, however, he didn't have acceleration skills, so it would take longer.

Xu Feng took out a gold-grade long whip from the storage ring and began the sacrificial technique.

The long whip was made up of white bones, like a spine, and when it was wielded, you could hear the clatter of bones rubbing.

The long whip was originally a strange soldier, and few people would use it, plus this long whip requires the use of the melee profession, but it increases the damage of the legal system, so that no one wants to ask for this weapon, and it has become a chicken-like existence for a while, just used for sacrifice.

Performing the sacrificial technique, the gold-grade long whip in his hand turned into a golden light and disappeared.

After a while, a translucent screen appeared in front of Xu Feng's eyes, which was full of creatures interested in this weapon, so as to correspond to the summoning of the sacrificial technique.

Next, Xu Feng only needs to choose one of them, and then cast a summoning spell to summon him to his side, so that he can lure away the two three-star elites.

"One star, one star, two stars, three stars, ......three stars, three stars" Xu Feng flipped over the interface and couldn't help shaking his head and smiling bitterly.

The immediacy of the sacrificial technique is too great, and last time it only used a black iron-level weapon to summon a four-star existence, but this time with a gold-level weapon, it turned out that the creature with the highest three-star peak strength was summoned accordingly.

What Xu Feng needs is to be able to lure the two of them away under the attack of the two three-star elite monsters, so that he needs to resist the attack for at least twenty seconds or more, even if the existence of the three-star peak, he is unwilling to complete this task.

"The peak of the three stars, I'm afraid that as soon as I see it, I will be split into pieces by the two undead guards." Xu Feng smiled bitterly.

Just as Xu Feng was about to end this sacrificial technique, a creature with six-star strength suddenly appeared on the interface list and summoned accordingly.

"Huh, mechanic?" Xu Feng took a look at the introduction of this creature, and his eyes lit up.

There were still five seconds left in the sacrificial technique, Xu Feng didn't say a word, and directly selected this six-star mechanic and cast the summoning technique.

A light gate appeared beside Xu Feng, and a pointy-eared creature less than half a meter walked out of the light gate.

"You...... Hello and thank you for your willingness to help me. Xu Feng saluted.

Although he used to be a six-star existence, Xu Feng is only a three-star now, and in the face of a six-star, due respect is still necessary.

"Hello, I'm Gehir, Earthling." The dwarf smiled, "A new planet, oh, seems to be facing an invasion ......"

"Yes, my home planet has just entered the Great Universe, and now it is facing the invasion of other planets, I hope to get your help." Xu Feng said.

"Oh, the Earth Spirit Clan only follows the divine cosmic trading rules, I don't know what I'm going to pay this time?_?" Gesil laughed.

The so-called cosmic trading law, according to the earth's dialect, is how much money is taken and how much work is done, and the pay and the gain must be proportional.

Xu Feng sighed slightly in his heart, there are many peace-loving aliens who don't mind giving more help to the invading planet voters, but more of them are just like Geishir, who are only willing to pay for their labor.

"Destroy these two three-star elite monsters at the door to complete the transaction." Xu Feng pointed to the undead guards at the gate of the ancient castle and said.

If the summoned is a creature with three-star elite strength, or ordinary four-star strength, then Xu Feng only asks the other party to lure these two undead creatures away for twenty seconds, but the other party is a six-star strength mechanic, then it should be very simple to eliminate the two three-star elites, and since he summoned it accordingly, then this low-level gold-quality long whip may have a special effect on him.

"Hmm, two undead creatures of three-star elite strength." Gehir pondered for a moment and said, "Yes, but you must give me the golden weapon in advance, and in addition, the materials dropped by these two undead creatures belong to me."

The items sacrificed by Xu Feng will not go directly to the hands of the trading partner, but exist in the hands of a third-party existence similar to the god of contract, and only after the transaction is completed, the items will go to the hands of the trading partner.

Xu Feng hesitated, once the sacrificial items were given to him in advance, it would be easy to take the things and not do anything.

However, thinking that the other party was a six-star strength, Xu Feng finally nodded and agreed.

For a creature with six-star strength, it is an easy thing to eliminate two three-star elites, and he shouldn't do such a tasteless thing...... Right?

"Good."

Seeing Xu Feng agree, Gehir nodded, reached out and grabbed the gold-quality long whip from the void.

Gehir groped every inch of the whip, carefully sifting through its materials.

After a long time, Gesil let out a sigh of relief and said, "It's really suitable."
