"Forty-nine non-attribute first-order mutant failed human metacrystals were exchanged, and a heavy truck from the technology plane was obtained."

"Heavy trucks, a means of transportation in the world of science and technology......"

Three exchanges in a row, and they were all exchanges of forty-nine first-order mutant failed human yuan crystals, and what they got was something like a game cabin heavy truck truck and a low-level body refining technique, no wonder Gu Jing was in a bad mood.

Regardless of whether these three things are equal to the first-order Yuan Crystal, let's first say that the holographic virtual game cabin is basically useless, in the last days, there is no network, no power supply, at most it can only be used as a portable bed, and this is still in the case that the drifting bottle can store and exchange items, otherwise Gu Jingdu will still think it is troublesome.

Let's talk about heavy trucks, in the last days it is still practical, you can drive on the road, with the volume and tonnage of heavy trucks, zombies are not a threat, and heavy trucks can carry a lot of daily necessities, as an RV, the cubic storage bag is still too small, basically there is nothing else except food.

But the most important problem is that Gu Jing doesn't know how to drive, and there are still some differences between heavy trucks and ordinary cars, Gu Jing is a novice naturally doesn't dare to try it, so he can only leave it in the drifting bottle and wait for when it comes in handy before taking it out, anyway, the function of the drifting bottle to store and exchange items has no time or space limit, Gu Jing must make good use of it.

Finally, there is the low-level body refining technique "Dragon and Tiger Bone Boiling Technique", which seems to be the most useful of the three items for strength growth, but in fact it is the most frustrating.

Although the drifting bottle can be automatically converted and applied for Gu Jing, so that Gu Jing can directly learn to practice this exercise, it is impossible for energy to be generated out of thin air, and the drifting bottle can only allow Gu Jing to master the trick, but it also needs some specific tonic assistance, which is very difficult to search before the end of the world, let alone in the last days.

Its effect is not satisfactory, and after Dacheng, it is only a little improved in the quality of the body, which is already a little unsightly for Gu Jing, who has been exposed to the magic of Xianxia magic and other planes.

In fact, by now, Gu Jing already had a faint guess in his heart, that is, the previous exchanges might have been a kind of similar preferential benefits to the first exchange, which greatly reduced the demand for energy, so Gu Jing could exchange for items such as puppets and storage bags Yitian Sword at a very small price. Now that the original price has been restored, there is not so much cheapness to take advantage of, so more energy is naturally needed.

Although Gu Jing was depressed in his heart, the exchange still had to continue, he had only exchanged more than a hundred first-order Yuan Crystals just now, but there were still more than six hundred in the drifting bottle, Gu Jing didn't believe that he would not be able to exchange good things.

"Exchange forty-nine non-attribute first-order mutant failed human element crystals."

"After the energy is drawn, the drifting bottle begins to be thrown into the world."

"The drift bottle has been salvaged, is it recalled immediately?"

"Yes."

"Forty-nine non-attribute first-order mutant failed human Yuan Crystals were exchanged to obtain the top-level magic weapon Qingjiao Banner from the Xianxia plane."

"Frog Banner, the top magic weapon owned by the disciples of Huang Fenggu of the Nether Cultivation Sect of the Xianxia World, there is a Frog Demon Soul in the Qi Refining Period sealed in the flag, which can summon a wind blade attack with spiritual power, and the Imperial Frog Demon Soul can fly in a short time with the addition of the body."

Gu Jing shook the drifting bottle, and saw a turquoise light cluster spewed out from the mouth of the bottle, and after the light was exhausted, a cyan banner about a zhang long appeared in his hand, the flag was full of blue light, embroidered with a vicious frog with teeth and claws, Gu Jing only looked at the scarlet bloody eyes of the frog, and felt an evil and killing aura attacking, which made him feel a shock in his heart, and he was in a trance for a moment before coming back to his senses.

"It is worthy of being a treasure in the Xianxia world, just looking at the momentum is extraordinary, and the power is even more extraordinary."

Gu Jing stroked the frog flag, which was as thin as silk, and it was silky and cold, and he couldn't help but praise it.

But when he thought about it, Gu Jing couldn't help but pull down his face, and a trace of annoyance appeared on his face. He himself is a mortal, he can't drive the Qingjiao Banner at all without spiritual power, and he can only look at such a treasure with greedy eyes, and he can't even summon a wind blade, so he can't do it, Gu Jing can only put it away, and wait to see if he can exchange it for the immortal cultivation method and cultivate spiritual power, and then there will be a place for the Qingjiao Banner.

Next, Gu Jing exchanged all the remaining zombie crystal nuclei in one go, a total of thirteen times, twelve of which were the top exchange of forty-nine first-order mutation failed human element crystals, and the last one also cost forty-one first-order mutation failed human element crystals, so many crystal nuclei, Gu Jing also gained a lot, but it was worth the money.

"F-level gene enhancement drug, made by the International Human Development Alliance of the World Science and Technology World, can initially strengthen the human genes, increase cell vitality, and improve various functions of the human body in an all-round way, including speed, strength, reaction ability, ......"

"The high-explosive ice potion, made by the pharmacy instructor of Sabia Academy in the Wizarding World, contains three ice elements that are extremely unstable in compression, and three high-explosive magic formations are engraved on the surface, which can be instantly frozen for a radius of ten meters after being broken."

"A low-level teleportation scroll, made by a space mage in the wizarding world, can be randomly teleported to any place within a radius of ten miles after being torn."

"The low-level spirit beast pill, refined by the Imperial Beast Sect of the Nether Cultivation Sect of the Xianxia World, can improve the cultivation of demon beasts to provide daily needs, and has an extremely powerful attraction to beasts."

"High Energy Particle Laser Gun, a laser weapon in the world of science and technology, can absorb ray particles in the air as energy to launch laser ......"

"The dragon elephant is like a skill, the supreme protector of the Tantric sect of the martial arts sect in the martial arts world, with a total of thirteen layers, its external power is strong and fierce, with the huge power of ten dragons and ten elephants, each move weighs a thousand catties, and the defense is superb."

Except for these six items, the other seven items were all messy miscellaneous items from the heavens and ten thousand worlds, which were useless, and they were casually thrown into the storage space of the drifting bottle by Gu Jing.

F-level gene enhancement potion, this thing is just right for Gu Jing to use now, although he also exercised often before the end of the world, and his physical fitness is considered good among the human population, but it is still far from enough in this last world.

Too many supernatural powers have emerged, and if you are not careful, you may inexplicably die in a certain elusive mutant beast or strange mutant plant, and now there is a genetic enhancement potion to improve Gu Jing's reaction speed, strength and other functions, and then cooperate with the weapons exchanged to assist in combat, which makes his life safety greatly guaranteed.
