"I've prepared it for you a long time ago, here is a book of building cheats, which contains all the magic circles about building magic weapons, with it, you can invent a lot of things!" Xiang Xu took out the building secret book that Ming Hao sorted out, this is the best casting method for building magic weapons, which contains a lot of miniature magic circles, including weight loss magic circles.

"Great, with it, I can build an air empire!" Chen Fei was very excited, this combination of magic circle and technology solved many of Chen Fei's inventions and technical problems!

"Well, you do it well, the bigger the better, tell you a big secret!" Xiang Xu was very solemn, the Three Realms Tribulation is very serious this time, once it hits the human world, the human world had better be prepared, at least have the ability to protect itself!

"Hmph, dare to come to the earth and see if I don't beat them up?" Chen Fei said, if this was in the Pangu Continent or the Outer Heavens, he would definitely be considered crazy by this little monk of the Guiyuan Realm!

"You don't know what we'll encounter in the Three Realms, if you don't have a weapon to restrain the powerhouses of the Immortal Realm, try to transfer the sentient beings in the Immortal Realm as much as possible!" Xiang Xu reminded that even the most powerful chemical weapon in the Human Realm would not necessarily cause harm to the Immortal Realm powerhouses.

"So powerful, then I'm sure I can research that kind of weapon!" Chen Fei knew the seriousness of the matter, but he was still full of confidence! "We just lack enough spars!"

Yes, there is no spare, Chen Fei is also a clever woman who can cook without rice, this is the biggest obstacle in the human world, Xiang Xu thought for a while and said: "Leave it to me, I will search the entire human world and dig out all the spars in those caves and blessed lands where there are no people!"

"The end of the human world, how many are in the cave heaven blessed land, I have been studying the structure of the spare, hoping to artificially make the spare!" Chen Fei said, there are few caves and blessed lands in the human world, even if there are, there are a few more masters, and once the inner spar is excavated, this cave heaven blessed land will be destroyed!

"It's unlikely, the production of the spar completely depends on the richness of the aura of heaven and earth!" Xiang Xu didn't believe it when he was killed, how did the spar come from is well known in the Pangu Continent and the Outer Heavens, the end of the human world, how could Chen Fei make the spare!

"It's unlikely, but we can try to transform the elements? For example, the thunder element, this is too easy in the human world, if you convert the energy into the aura in the spar, you can find something to store, just like a battery, then it will be successful!" Chen Fei said with a smile.

"Don't say it, it's really possible!" Xiang Xu's eyes lit up, the elements are different from the aura, the end of the human world, the less is only the aura, but the element particles are not a lot, because human beings themselves will make electricity, fire, and other elemental particles, many times Xiang Xu thinks that science and technology is also a kind of Taoism, and it is more profound and profound.

"Yes!" Chen Fei was very excited, he looked at it directly, the more he watched, the more excited he became, and finally took the cheats and rushed out of the door!

Xiang Xu left all the spars on his body to Chen Fei, and decided to find those ownerless caves and blessed lands, get more spars, and bring Gu Ting'er, Gu Xiang'er, Chen Chu, Lu Ming, and Gu Yuejiao to the Yuxumen Cave Heaven, Xiang Xu rested and instructed them for a month, and then left alone, looking for that kind of cave heaven blessed land, and most importantly, to find the Huangquan Road to the underworld, counting that he had been away from the Pangu Continent for almost ten years, Xiang Xu wanted to go back immediately, and his mother must be alone in penance.

Unconsciously, another year passed, this year Xiang Xu found hundreds of caves in the entire human world, there were only a dozen ownerless, Xiang Xu got a large number of spars, and there were some Jieshi, Xiang Xu was useless, these can be used for Gu Ting'er, Lu Ming, Chen Chu and other children to grow and cultivate.

As for those caves with masters, Xiang Xu was very polite, sat down and discussed, discussing the cultivation experience, there are very few monks in these caves blessed land, only a few people, and most of the cultivators are in the Guiyuan realm, and there is no one who has reached the Jindan period, seeing Xiang Xu's such a powerful cultivation, these monks even think that the portal of the Three Realms has opened again!

While Xiang Xu was traveling in the Western Continent, Yu Peng called, saying that a natural pit had been found in Mongolia, and after exploration, it was suspected that it was leading to the underworld!

Xiang Xu received the call, and immediately flew back, directly to the Mongolian sinkhole, all the Xiang family army was stationed here, even Ye Xiaoling and Yu Peng were there, Xiang Xu came, the entire Xiang family army regained their fighting spirit, and the disappearance of the three soldiers swept away the haze.

"Brother Xiang, you're here!" Yu Peng was very happy to see Xiang Xu, in the past year, the Chen family has developed a large number of new weapons and warships, and they have sent humans to Mars, not to mention those powerful weapons, it is not a problem to blow up the moon.

"Tell me the actual situation?" Xiang Xu hurriedly asked, the sinkhole leading to the center of the earth may really be the road to the underworld.

Yu Peng didn't hide it, he said it 1510, this place was still discovered by local herdsmen, the earth's crust suddenly collapsed, and then formed such a huge pit that was thousands of meters wide and bottomless, and all the grass and trees in a radius of several miles on the edge of the pit turned black, and as long as the cattle and sheep ate it, they would definitely die.

"Is there any animal that eats black grass, I'll see!" Xiang Xu asked.

"Yes, come here!" Yu Peng led Xiang Xu to a dark corner, where there were a few cattle and sheep, their whole bodies emitted black gas, the pupils of their eyes disappeared, all the whites of their eyes, but there were no scars on their bodies.

"Tell everyone nearby that people and animals are not allowed to approach within a radius of 100 miles, and all cattle and sheep species that have approached are to be slaughtered and buried on the spot! As for human beings, all of them are imprisoned!" Xiang Xu said, his expression was very solemn, this black gas represented the ghostly qi, which was indeed the breath that seeped out of hell.

"Okay, I'll arrange it!" Yu Peng saw Xiang Xu so dignified, and he also knew the seriousness of the matter, this may be no less than a plague, and it must be quickly controlled!

"Slow, you can find someone to get a large amount of Yang Returning Grass, which is found in all places in the south where there is a surplus of Yang Qi, and anyone who has used this kind of beef and mutton must take it for a long time, otherwise the consequences will be very serious!" Xiang Xu said.

"Okay!" Yu Peng agreed and left, leaving in a hurry, there might be too many lives lost if this matter was delayed for a moment.

"You're here!" Ye Xiaoling walked over, looking a little depressed!

"Have you gone down?" Xiang Xu frowned, Ye Xiaoling's Yintang turned black, obviously invaded by the ghostly qi.

"Well, I don't know what's going on, my body is a little cold after I came up!" Ye Xiaoling finished speaking, shook her shoulders and shivered.

Xiang Xu took Ye Xiaoling's hand, ran the Yin and Yang Five Elements Diagram, and quickly absorbed the ghost qi in Ye Xiaoling's body, this ghost qi was fortunately not very strong, so it was absorbed by Xiang Xu's Yin and Yang Five Elements Diagram, and was quickly decomposed into the Five Elements by Xiang Xu, Ye Xiaoling felt relaxed for a while, her head didn't hurt anymore, and her body was also strong, as if she had removed the shackles in an instant!

"Don't be too happy yet, how many people have gone down, call me out!" Xiang Xu stopped Ye Xiaoling's cheers, even Ye Xiaoling in the realm of the Great Perfection of the Returning Yuan was infected by the ghost qi, not to mention those soldiers in the middle of the Guiyuan Dynasty!

"Okay, I'll call them out!" Ye Xiaoling hurriedly ran out, and after a while, more than two dozen soldiers came over, their faces were full of black gas, depressed, and the symptoms were the same as Ye Xiaoling's, and even black threads appeared in both eyes!

Xiang Xu didn't dare to hesitate, one by one began to absorb the ghost qi in their bodies, the so-called ghost qi of the netherworld, is also a kind of yin qi, Xiang Xu's Yin and Yang Five Elements Diagram can just be absorbed and decomposed, and converted into normal energy, but these soldiers are different, they are basically the five elements of the spiritual root, infected by the ghost qi, will only be slowly eroded soul, those cattle and sheep who eat the black grass are the result of the soul being worn out.

It took Xiang Xu more than an hour to absorb the ghostly ghost qi in these people's bodies, and then Xiang Xu didn't have time to rest, and began to set up a formation around this sinkhole, Xiang Xu arranged the Tiangang Sealing Array, Tiangang is yang, and it can temporarily suppress the ghostly ghost qi that comes out of hell.

It was a long night before Xiang Xu finished arranging, activated one of the talisman arrays, the sky was as bright as day, and even those black plants and trees slowly changed back, and all the soldiers were elated, cheering for their honorary commander!

"Report to the sir, these plants and trees have changed back, so can the herdsmen here continue to graze?" asked a non-commissioned officer.

"No, these plants and trees must be exposed to the sun for seven days and forty-nine days to be absolutely safe!" Xiang Xu said, now these plants and trees have indeed recovered their color, but after all, they have absorbed the ghost qi of the netherworld, and there must be ghost qi in the cells.

"Xu, what the hell is down here?" Ye Xiaoling asked, they didn't see the bottom for more than a thousand meters, but were blown down by a gust of wind, and the three of them didn't hear the sound of landing for a long time.

"This should be hell below, that is, the eighteenth layer of hell in the underworld!" Xiang Xu said, because only the eighteenth layer of hell has such a strong netherworld ghost aura, which can erode people's souls in a muddy way, and they don't even know if they die out of the body.

"Is it really eighteen layers of hell?" Ye Xiaoling asked, and some of the soldiers didn't believe it.

"Well, I'll go down in person in a while, you must not step into the formation!" Xiang Xu said, except for himself, no one can resist the erosion of the hell ghost qi, and the hell ghost qi leaked out, it must be because something opened the gate of hell on a certain layer.

"Can you go down by yourself?" Ye Xiaoling asked worriedly, after all, it was the eighteenth layer of hell, and the people of Huaxia all knew what the eighteenth layer of hell represented, how terrifying it was!

"Don't worry, the underworld has been extinguished, there should be no powerful ghosts in it!" Xiang Xu said, the eighteenth layer of hell is at most evil ghosts and ghosts, he is good at Xuanlei, just restrained, and Xiang Xu must go down, because the eighteenth layer of hell must be linked to the underworld, only by finding the underworld, he can return to the Pangu continent!

"Okay, be careful, we'll wait for you to come back!" Ye Xiaoling stepped forward and hugged Xiang Xu.

Xiang Xu prepared everything, and jumped down directly! This sinkhole is really too deep, Xiang Xu jumped down and instantly opened the sealing talisman, the talisman, and opened the eye of heaven at the same time, the surrounding yin wind was very strong, Xiang Xu slowly flew down, a few thousand meters later, magma appeared, rolling magma, and it was still in a quiet state, as if the sinkhole had not passed through at all.

Continuing down, the sound of ghost crying began to appear, Xiang Xu had to stop, the ghost sound was terrible, as if it came from all directions, Xiang Xu carefully observed, and at the same time silently recited the pure heart decision, to resist the erosion of this ghost sound.

After another thousand meters down, nicks began to appear on the surrounding stone walls, Xiang Xu stopped, looked carefully, and looked around Xiang Xu was already prepared in his heart, and he couldn't help but be frightened, Xiang Xu muttered to himself: "Pull out the tongue hell!"
