As for the direction of the exchange, of course, the two of them would not waste Hantang's limited time to discuss this issue, as early as in reality, the two had already discussed it.

After giving up the opportunity to sign a contract with powerful necromantic creatures, Zheng Wei's deep gloom meditation in exchange for it greatly strengthened his perception of the other world, and through his affinity for necromantic energy, Zheng Wei was able to choose a variety of low-level evil creatures such as skeleton warriors, shadow poisonous insects, and crypt spiders. After breaking through the limit of summoning once a day, the only thing that restricts the number of summons is his own soul strength, and the more powerful the summons, the more they need enough soul power to control and communicate. Without counting Zheng Wei's mana recovery speed, Zheng Wei, who was full of summons, had more than doubled his strength compared to the previous world.

In order not to let magic become his biggest shortcoming, Zheng Wei had to spend 1200 general coins to raise his magic power, according to the division of magic power in the Azeroth continent in Karl's notes, Zheng Wei's magic power at this time was about 6.7 level, barely breaking through the threshold of magic apprentices and reaching the level of a second-level magician.

It is foreseeable that as each level becomes more and more difficult, the number of universal coins required in the future will inevitably increase exponentially, and it is even impossible to improve it in such a rough way through Hantang, but for the two people who urgently need to save their lives at the moment, this is a high cost that has to be paid.

After selling the pistol, Zheng Wei still had 1,500 points of general coins left, and he spent 600 to exchange for a complete set of multi-functional combat suits, which are made of composite materials that can fit the body parts below the neck, and have good defense against sharp objects such as swords and all kinds of common corrosive liquids. As for the long-range defense function that the two value, this combat suit can withstand the fire of ordinary small-caliber pistols from tens of meters away, and the three-piece alloy material reinforced on the chest can withstand the burst fire of ordinary rifles.

In terms of cost performance, this combat uniform is already the best prop that Zheng Wei can find from his own list over and over again. Although it was a little too weak in the face of the electromagnetic-powered guns and various special bullets of their time, if they faced the Chu Fei people they met in the previous world, this combat uniform could even directly influence the battle situation, greatly reducing their losses.

Among the remaining general-purpose coins, Zheng Wei set aside 500 as the cost of teaming up for the next entry into the mission world, and originally planned to use the last 400 general-purpose coins to exchange for one-time attack props such as grenades, magic scrolls, and powerful puppets, but after comparing the exchange lists of the two, the two found that the corresponding items on Liao Yu's exchange list were actually cheaper, about 9 to 9.5 discounts, which may be because Liao Yu and Zheng Wei's abilities began to differentiate significantly.

Although this price difference is not much, for the two people who must compare the baht at this time, it is a little bit to save a little. If it weren't for the fact that the items exchanged by Hantang couldn't be traded, just by adjusting the price according to one's personal ability and physique, Hantang could quickly develop a set of market rules that belonged to explorers.

After a long discussion, the two abandoned the high-explosive grenade and instead exchanged 300 generic coins for a flashbang and a disposable scroll sealed with a high-grade magical high-temperature fire cloud. This magic can summon a cloud of fire covering about 20 square meters, and the high temperature of the magic flame is more difficult to extinguish than the usual flames, and it also has a high level of damage to the soul body.

Zheng Wei, on the other hand, exchanged 300 general coins for four pills to repair soul damage and a scroll of primary group healing, the former can repair some damage caused by simple curses and backlash for the spirit world, and the latter can speed up the healing of physical injuries.

It's just that when it was Liao Yu's turn, he hesitated, but after a while, there were two thick paper books in his hand, and the spine of the two books was engraved with their respective titles in different styles. Liao Yu and Zheng Wei both recognized the author's name Lofele Barber under it, which was made up of a mixture of magical mercury and earth fire essence gold in a specific proportion, a detail that vaguely revealed the status behind the author.

On the spine of another book, intricate and three-dimensional flower branches are outlined in deep purple, and a few simple and subtle symbols are eroded out of dark red unknown material in the center.

Technology is the cornerstone of a country's and nation's progress, and so is knowledge for individuals.

Zheng Wei was not surprised that Liao Yu exchanged these two books, and the emotions revealed in his eyes were more curious than doubtful.

"It cost 400 general coins, but it's worth the money, the former is a grand mage of the Magic Association, and Hantang's introduction is that this archmage has been a teacher in his Deep Blue Academy for more than 50 years, which is a general textbook compiled by him."

Liao Yu flipped through the first book, and then handed it to Zheng Wei, no matter from the words on the outside and the preface inside, this really looks like a book written by a respected academic elder.

"As for this one? Anyway, the introduction is a record of other world experiences.,This is some essays left by an otherworldly wizard called a traveler.,Somehow it was collected by Hantang.,The content inside is all translated.。 According to the price of Hantang, these things are worth the money. If you want to communicate with the necromantic creatures of another world, you can take this book first, and I'll take a look at this textbook against the notes from last time. ”

Liao Yu handed Zheng Wei the book of experiences in another world with a dark cover in his hand, and exchanged it for the magic material illustrated book.

Zheng Wei sighed lightly and said, "In this way, you are not too much of a loss." ”

"Okay, where do you care so much, my current magic power is similar to yours, relying on universal coins to improve the cost performance is very low, what I need now is accumulation, I hope the next mission is not too urgent."

After Liao Yu finished speaking, he put the book into the storage space, turned around and was about to leave.

"You're not going to exchange anymore?" Zheng Wei was stunned.

Liao Yu waved his hand behind him and said, "No need, let's go and see that Phantom Luo Beast first, I still have a magic gathering array in my hand, and I will exchange materials together after the matter is resolved." ”

Seeing Liao Yu say this, Zheng Wei also put away the book and left with Liao Yu.

In the afternoon of the same day, the two went to the pet store that Chen Siyu said in the name of petting the cat, and stayed in the store for more than two hours while drinking coffee, and heard the news of the kitten.

After having an accurate address, the two of them slowly sketched a picture in their minds with the help of the few imprints that still remained in the spiritual world. In the middle of the night, when no one was there, only the small sleep lamp in the store was still glowing faintly, and the cat was lying lazily in the orange kitten house in the corner, looking boredly at the still bright human world outside.

At this moment, a Phantom Beast passed through the ceiling in the southeast corner and slowly walked through the entire pet house. Everything in reality was meaningless and illusory to it, and as he wandered past the cute little kitten, its fluttering tentacles accidentally took on the characteristics of influencing reality, sliding over the neck of the poor little one, and the little guy also saw this terrifying monster that he had never seen before in this short moment, especially the instant disappearance that broke its long-established view of cat life.

Liao Yu and Zheng Wei found out almost all the roads that this Phantom Luo Beast had traveled during their stay, and after exploring back and forth around the vicinity of this pet store for several laps, relying on Liao Yu's mental power to lock, the two finally determined the direction of the Phantom Luo Beast's appearance from the slight traces remaining.

"Did you say this guy is still there?"

Zheng Wei stared at the residential buildings diagonally above with a bitter expression, after such a series of tracking, Zheng Wei was very skeptical that this creature was still staying in their city.

Liao Yu was also full of hesitation, he reached out and touched his chin, estimating the distance between the residential building above and the pet store.

"How can this be said accurately, the strength of the Phantom Luo Beast is not strong, and it basically does not have the strength to cross this world alone and go to another world. This is the same as your summoning, at this stage, those low-strength summons need you to recite spells and communicate the channels that originally existed in the spiritual world in the other world before they can be summoned to this world, which shows that it is not so easy to cross the barrier between the two worlds. ”

"Let's go, let's go, let's go up and have a look, even if I don't find it in the end, I just go to that business circle for a meal."

The two took the city elevator again to the middle level of the entire city, but because the two did not have the ability of the spirit creature like the Phantom Luo Beast to travel through the real world at will, after stepping out of the elevator, the two almost lost their already faint traces.

The city is like a vast forest of steel, with traces that sometimes stretch to the shops on one floor below, and sometimes wind upwards to squeeze into a restaurant overhead. The two had to take the elevator back and forth to shuttle up and down this area, but after a few large circles in succession, the two of them were never able to find the exact trace of the Phantom Luo Beast, and they could only determine that it had stayed in this area or even lived for a long time through the vague residual breath.

"If only you could summon necromantic creatures and use their senses to help lock them on."

Zheng Wei complained in a low voice, as magical creatures, they could completely enter places like ventilation pipes that Zheng Wei and the two could not go to for detection, and at the same time, they could also increase the scope of exploration.

"Forget it, let's look for it honestly, we have to go in today with your summons."

In a society where all public places are filled with cameras, from the sky to the ground, it is almost impossible to do anything to avoid surveillance in public. And if something as strange as a necromantic creature suddenly appeared in the business district, Liao Yu would hardly have to think about it to know what kind of life he would be in for the rest of his life.

"Did you really leave?"

Just when Liao Yu couldn't help but think of this thought, the door of a residential unit not far away was suddenly opened, and a man hurriedly swiped his card out of the door with a shoulder bag. However, through the gap in the door of the alloy unit that had not yet been closed, Liao Yu clearly sensed the thick aura of the Phantom Luo Beast at the door.
