The three-month vacation has long passed, and it will be at least another month or more before I can return to the underworld. The dangerous and exciting adventure is not over, but it has been changed from the surface to the underground passage.

There are thousands of underground passages, more complex than a spider's web. Ninety percent of the underground passages are pitch black, and ninety percent of the passages are extremely dangerous. In addition to the complex natural environment, the underground passages are full of miasma, fur, poisonous spores, invisible dead light (radiation) and other invisible invisible killers. In addition, there are many strange and terrifying plants, animals, and microorganisms in the underground passages.

Fortunately, there are three geographical experts in the team: Ding Yi, Meng Chan and Dai Xiaoxue. In advance, they made a phantom disc of all kinds of dangerous situations, dangerous animals and plants that are commonly seen in the underground passage, and introduced them to everyone. At the same time, Ding Yi appointed Xue Ren as the picket of the team to correct the troublemakers in the team at any time. Tie Zhongtang was appointed as the arbitrator to deal with violations of discipline within the team.

Underground passages are very dangerous, and the slightest carelessness can cause serious casualties. Often, because of the recklessness and recklessness of a very few people, it will bring disaster to the whole team. Zhou Yu and Ma Yuan were all punished by Tie Zhongtang's lessons.

In addition to the treasures that can be seen everywhere in the underground passage, it is a treasure land with extremely rich cultivation materials, and it is also an adventure paradise and leisure resort. Salt sand baths, hot springs, cold springs, asphalt lakes, sulfur lakes......

In addition, the large and small fault spaces of the underground passages, the fantastic natural scenery, and the majestic landscapes are fascinating. In the case of sufficient safety, the trip to the underground passage is still a very good journey.

The biggest unsafe hidden danger in the team is Zhao Yong's spirit pet Violent Demon Ape, and Ding Yi's spirit pet Flying Tmall Little Ash. As for Xiao Hei, he was originally a native of this underground passage, an existence at the top of the food chain, and Ding Yi was very relieved about this demon beast.

There are five people in the team who have animal trainer qualifications. In addition to Ding Yi and Zhao Yong, there is also Hong Sheng, a half-hanger, as well as a teacher named Liu Tong and a female cultivator named Yi Hai. Liu Tong and Yi Chai are both dual-spirit qualifications, Liu Tong in addition to the beast tamer qualification, there is also a dark spirit qualification, he was originally a teacher of the Xuanzang Academy to teach dark spirit spells, Yi Hai's main qualification is the wood spirit qualification, and her beast tamer qualification is worse than Hong Sheng.

After entering the underground passage, Ding Yi was regrouped, and the four people were organized into a group, and Zhao Yong served as the team leader. Zhao Yong has extremely high expectations for entering the underground world, and what he wants here is to have a yuan-level spirit pet. After seeing Xiao Hei's extraordinary, he dreamed of making a spirit pet that was different, preferably like Xiao Hei with great strength.

For this reason, he asked everyone in the special operations team to be sure that when they were exploring the way ahead, if they found a high-level extraordinary demon beast, they must stay alive and notify him.

Zhao Yong was still dreaming like this, he didn't expect that his demon pet Violent Demon Ape and Ding Yi's Flying Lynx Little Gray would bring him endless troubles along the way.

The Violent Demon Ape is just a cute and naughty little monkey without transforming, the Violent Demon Ape is not small, and the curiosity is very heavy, the key is that this guy is very smart.

The strange natural scenery of the underground passage and the strange food made this little monkey curious. However, there are certain rules of safe operation for the team to operate in the underground passages. In the vast majority of cases, all people are active outside, and they are in mechas. Like the Violent Demon Ape and the Flying Lynx Little Ash, safety containers are specially prepared for them.

These two spirit pets, who are usually free and casual, can bear to lose their freedom. So the little monkey tried to escape all the way, and by a little carelessness, the little monkey ran outside.

In most cases, the little monkey didn't get far before it was caught. The strength of the Violent Demon Ape has not yet fully recovered, and it was originally at the middle level of the Xuan level, but even if it transforms now, its strength will only reach the high level of the spirit level. There is just one person in the team, all with a Xuan-level war puppet on his body, and he can catch this mischievous little monkey back in minutes.

But there were still two times when the clever little monkey ran out of the camp, but fortunately the little monkey did not encounter a poisonous miasma, a furious gas, or a fierce beast outside, and the little one ran back to the camp after playing wild outside for a few hours......

Flying Lynx Little Gray, also an unconscious master, this little thing, although its IQ is not as good as the little monkey, but this little thing, has a magical space ability. The comfort zone made for it can't be shut up at all. If you are not careful, it will disappear from under everyone's noses......

Zhao Yong's work was very tedious, in fact, after entering the underground passage, this team, which was only escaping around in the surface world, was transformed into a scientific research team. Zhao Yong has to observe, record the habits of underground creatures, compile underground animal atlases, and sometimes, he also conducts dissections, experiments, goes to the field, conducts environmental surveys, and so on.

These two troublemakers made Zhao Yong physically and mentally exhausted.

Walking a lot at night, you will eventually meet ghosts, flying lynx little gray, not afraid of the sky, not afraid of the earth, this wild little guy, finally one day, after sneaking out, as soon as he came back, he fell ill.

Flying Lynx Little Gray, originally a little ugly, disabled Flying Lynx, after it got sick, the original mottled and impure hair, began to fall off a lot, and the appearance became uglier.

Ding Yi suspected that this little thing was likely to have suffered from miasma poison gas. Flying Tmall Little Gray is a little cold, even for its owner, it is also a pair of arrogant expressions that ignore it. However, Ding Yi has a very deep affection for Xiao Ash.

This was the first partner Ding Yi met when he set foot in the cultivation realm. Ash accompanied him through his illustrious college career, and then they were separated for nearly nine years. Flying Lynx Little Ash, in Ding Yi's heart, has long been regarded as a part of his life.

Jiang Yuhan, an expert in the poison group, Yi Xiaomei, an expert in the medical team, and Zhao Yong, an animal trainer, would come over for a few hours every day to discuss Xiao Ash's condition. They formed the medical team that treated Ash.

Ding Yi and the others conducted countless poison and drug research, laboratory analysis, and wanted to cure Xiao Ash. But there has been little progress, and everyone is very sad to see that the little guy who was lively and active is getting thinner and thinner, and his spirit is sluggish.

Ding Yi tried his best, he even drew a small tube of blood from Xiao Hei's body, wanting to extract an antiviral elixir from Xiao Hei's blood to heal Xiao Ash, but it didn't work.

Looking at Xiao Ash lying in the isolation ward, Ding Yi's heart was like a knife.

In order to prevent the violent demon ape, this situation also occurred, and Zhao Yong brought a special collar to it. A few active guys in the team are now a lot more honest.

Unlike when they came, this time they returned to the underworld, and the number of people exceeded three hundred. Among them, there are more than thirty captives, and the speed of the team's march is not as fast as when it came out, not to mention that Xiao Hei's strength has not yet recovered, and it is estimated that it will take at least two months to return to the underground world.

Frequent crustal activities will cause some underground passages to collapse, and at the same time, new underground faults will be generated, and new passages will come out, which is the biggest trouble in returning to the underground world. Although Ding Yi and the others are like arrows, they can't do it in one step when they return to the underground world, and there must be a gradual process.

The captives were very conscious, along the way they saw a lot of incredible landscapes, and under the leadership of Ding Yi, they saw a lot of terrifying and mysterious species, some of them thought at first, this time with Ding Yi to the underground world, remember the marks along the way, and wait until they reached the underground world to see if they could sneak back.

After they entered the underground passage and walked for only one day, they decisively abandoned the idea. The underground passages that change from time to time, the miasma poison that fills everywhere, and the 100-meter-thick rocks that block the way......

Even if they can break free, even if they are great grandmasters, it will be very difficult for them to return to the surface world safely.

Without a mecha suit, without Ding Yi's spatial supernatural powers, Xiao Hei's spatial abilities, and without Ding Yi's rich experience in underground passages, returning to the surface world is mostly a life of nine deaths. Even if they were able to return to the surface world, it would be very likely that they would become, the mutants that Ding Yi told them.

The captives are all capable of cultivating truth, and their knowledge and vision are far beyond ordinary people. They quickly adjusted their mentality, not only did they not make trouble for Ding Yi and them along the way, but some of them have begun to gradually integrate into this collective.

Shen Yiyi, a poison doctor, was the first to be freed. She has Jiang Yuhan as a guarantor, and her performance along the way has also been affirmed by everyone, not long after she entered the underground passage, especially after the misfortune of Xiao Ash, after everyone's unanimous agreement, she was released from prison.

As for the others, they are still under supervision for the time being.

In order to facilitate everyone's actions, the device team made a lot of weight-bearing puppet reptiles under the guidance of Ding Yi. In addition, the team also made a lot of puppet insects, which were handed over to the investigation team for use.

The monks of the reconnaissance group, their mission, in addition to exploring the various areas of the underground passage, also has to do a good job of marking the passage, using the brain, and editing the map.

The main task of the special operations team is to hunt down underground monsters and obtain food for the team, and at the same time, they also serve as the guards of the wood spirit monks, earth spirit monks, and beast tamers in the team. Help them collect a variety of flora and fauna, survey ore veins, and guard captives to keep the camp safe.

At the beginning, this group of surface monks who escaped from the sky, when they entered the underground passage, it was inevitable that they would have some psychological expansion. Their own strength is one thing, but because each of them has more than two Xuan-level war puppets in their hands, and without the powerful cultivators of the empire to chase and kill, once their nerves are relaxed, they will inevitably have some deviations in self-perception.

Salt crystal caves catch cantharids, peat lakes tickle knife-tailed crocodiles...... Most of these guys are Ding Yi's relatives and friends, and Ding Yi can't punish them. If it weren't for Ding Yi, Xue Ren and Tie Zhongtang had been appointed in advance, serving as pickets and arbitrators respectively, and these people didn't know that they would make crazy moves.

Fortunately, after a few days, some of the people were severely punished by Tie Zhongtang, and after a few days, they saw the appearance of the little gray bones and thin shape, and everyone finally had a clear understanding of the underground passage. Didn't do anything out of the ordinary again.
