Compared with the combat mecha, the construction of the stealth ship is simpler and more practical, mainly used for long-range reconnaissance and patrol, to provide enough intelligence and basic defense force for the airship, so the energy consumption is much smaller, and it is also easier to study.

Although the sea of nothingness will devour all the energy, but in the final analysis, this is affected by the power of space, and the cultivators may have some nothing to do about it, so they can only take the method of hard bearing, but the goblin clan is extremely advanced in science and technology, and has an extremely in-depth study of space power, although the goblins under Xiao Chu's hand do not have the means of transportation to counteract the power of space devouring for the time being, but it is still possible to study the ready-made things thoroughly and use them.

The biggest and only problem is that the energy required is too large, and all that is consumed is the energy spar, which is for the declining goblin clan, just starting these machines and then exploring the energy spars they need, is something they can't afford. Fortunately, now Chen Gong has specially allocated a part of the energy spar for them to conduct special research.

Originally, Chen Gong was going out this time to go alone, but Xiao Chu volunteered to recommend their goblin clan's stealth ship to Chen Gong, and contributed his son to Chen Gong as a full-time driver. Xiao Chu knew that being able to stay by the sect master's side and listen to the sect master's teachings from time to time didn't know how great it was for his son.

Chen Gong has always had a lot of interest in scientific and technological products, especially when he heard that the mecha used by the mecha division in battle was actually made based on the combat machinery of the goblin, so he paid more and more attention to the goblin technology.

During this trip, Chen Gong actually wanted to use the huge devouring power of the Sea of Nothingness to suppress the huge and complex true elements that were about to be absorbed from the enemy in his body, and then successfully break through to the merger stage. Moreover, Chen Gong had been thinking about the True Yuan Body Refining Method for a long time, and he also knew that this cultivation method might only be able to find it in the Sea of Nothingness filled with the power of time and space.

It's just that this Sea of Nothingness is not a safe place, just in terms of its degree of danger, I am afraid that it is far above the Southern Wilderness County, which is chaotic and orderly, and has its own rules of survival, but the Sea of Nothingness is completely a place full of dangers, especially the kind of energy-devouring characteristic, which almost makes all cultivators fear it like a tiger.

If Chen Gong wants to cultivate in the Sea of Nothingness with peace of mind, he has to rely on the power of some foreign objects, and some protective magic weapons in the cultivation realm are obviously not capable of such a thing, even if Chen Gong's research on the formation method is used, he can't find a formation that can provide continuous protection for himself in the devouring power of the Sea of Nothingness, so scientific and technological products have become his first choice.

The stealth ship has good concealment and detection functions, although the armor of the hull is not thick, but it is enough to deal with ordinary small sea beasts, as for those large and surprising beasts, with the detection range and speed of stealth, they can be easily avoided.

After entering the depths of the Sea of Nothingness, Chen Gong would ask Xiao Jianxing to turn on the stealth function of the stealth ship every day, find a relatively safe place, cultivate, and rely on the ubiquitous power of time and space devouring to compress and refine the true yuan power in his body.

In his spare time, he will naturally guide Xiao Jianxing's cultivation, but Xiao Jianxing's cultivation talent is excellent, which makes Chen Gong both satisfied and worry-free. Time passed day by day, and before I knew it, more than three months had passed.

"I heard Elder Nanxuan say that your goblin clan once created an extremely brilliant scientific and technological civilization, but why did it decline so quickly that it was even impossible to gain a foothold in the continents?" After a day's cultivation, Chen Gong returned to the interior of the stealth ship and asked Xiao Jianxing, who had also finished his cultivation.

Looking at Chen Gong's kind and kind appearance, Xiao Jianxing couldn't help but feel a little stunned, if he hadn't seen it with his own eyes, who would have known that the man in the human world in front of him who was like a sunny boy was a powerful existence that could easily kill a cultivator like the Blood Demon Ancestor.

It's just that after hearing Chen Gong's question, an indescribable expression appeared on Xiao Jianxing's face, as if he was remorseful, regretful, and reminiscing......

"In addition to the pursuit of technological civilization, our goblin clan's greatest interest is to explore unknown territories. Perhaps because of our small stature, others have turned their attention to the sea or the sky, but we are locked in the deep and mysterious underground. Xiao Jianxing and Chen Gong have been alone for a while, and they know that this sect master usually doesn't put on any shows, and he is not polite at the moment, so he said directly.

Regarding Xiao Jianxing's opening remarks, Chen Gong had a little more appreciation for the goblin clan in his heart. He remembered that when he was doing scientific research on the earth, he remembered that someone once said that human beings are too ambitious, and even the earth under their feet has not yet been explored, but they always set their eyes on the vast universe, which is really a waste of resources.

Although this is a bit extreme, but it also has its truth, thousands of high-rise buildings from the ground, sometimes because the vision is too long-term, and ignore the things in front of you, the same will suffer.

"In the exploration of the underground, we have found many interesting things, rare ore veins, magical creatures and powerful energy, in the face of these mysterious unknowns, our ancestors of the goblin clan are deeply lost, and their exploration of the underground is almost crazy, until the day comes. Xiao Jianxing said this, it was a meal, with his age and experience, these obviously could not be his personal experience, but as the young patriarch of the Tengshan Department of the goblin clan, these allusions in the clan, Xiao Chu would definitely tell him from time to time, so the pause at this critical moment was also copied by him.

The legend and story in this, Nan Xuanrui also once told Chen Gong, but there are a lot of hearsay here, and there are a lot of artificial processing, and I heard the descendants of the goblin clan talk about it in person, this is the first time, so when Chen Gong heard this, he couldn't help but feel a little interested, and his expression seemed a little focused.

Xiao Jianxing had completely entered the role of the narrator at this time, and seeing that Chen Gong was listening to himself very carefully talking about the history of the clan, he couldn't help but feel a little complacent, and quickly continued: "The Source Realm is so big that no one knows where its boundary is, at least no one has ever reached the end of this sea of nothingness. Our ancestors of the goblin clan also didn't know how wide this source realm really was, but they once had an idea that even if they didn't know the size of the source realm, they should at least explore the depth of the source realm. Perhaps they were once extremely close to this goal, as they discovered a suspected subterranean limit of the Source Realm. If this speculation is true, it can be considered to be the boundary of the source underground. ”

"Is that the underground boundary of the Source Realm?" asked Chen Gong with some curiosity.

Xiao Jianxing shook his head with a wry smile and said, "I don't know, because our ancestors didn't have a chance to confirm that when they discovered that chaotic underground space-time, they also found a powerful creature, or a powerful demon. It is such a demon that has led our goblin clan into a state of no return. ”

Chen Gong had also heard the story of a demon drawn by a goblin who destroyed the continent, wiped out all the civilizations it could see, and devastated the entire continent. Chen Gong didn't believe it at the beginning, if the goblin technological civilization was really as powerful as Nan Xuanrui said, their clan at least had a strong force no less than that of the monks of the Tribulation Period, in the face of such force, what kind of demon could destroy it, could that demon be the existence of the Mahayana period?

Regarding the history circulated in these ethnic groups, Chen Gong has always looked at it with dialectical thinking, removing the false and retaining the true, and finally found out the truth hidden behind the story.

Maybe the goblins really discovered some powerful creatures, or maybe they just created some technology, and finally used this as a fuse, causing the decline of the entire race.

However, these are not what Chen Gong intends to discuss with Xiao Jianxing today, and there is no result in the discussion, because Xiao Jianxing stopped when he talked about this, because there is no follow-up record in the classics of their tribe.

At this time, a sharp alarm sounded inside the stealth ship, and bursts of red light flashed, pulling Xiao Jianxing back from the memories of the clan.

"What's going on?" Chen Gong frowned slightly, in the Sea of Nothingness, although he was not worried about the devouring power of the Sea of Nothingness because his body had experienced the tempering of the storm of time and space, but the detection range of the spiritual sense here was greatly shortened, and many times the detection of the spiritual sense was not as good as the detector of the stealth ship.

"Sect Master, there is a huge Void Sea Beast coming over here, judging from the current intelligence analysis, it should be the Void Sea Snake. Xiao Jianxing fiddled with the console for a while, and then quickly gave Chen Gong a reply.

"Void Sea Snake?" Chen Gong was slightly stunned, it was a Void Sea Beast that could generate space-time stones, and the value of space-time stones was still above citrine, if it weren't for the fact that he wanted to control his power and suppress the cluster of demonic thoughts in his heart, it would not be appropriate to kill, Chen Gong was really interested in looking for trouble with these sea beasts in this sea of nothingness, and see if the space-time stone only appeared in the body of the Void Sea Snake, or if other sea beasts could also contain such heaven and earth treasures.

"Yes, Sect Master. Judging by the energy fluctuations around the Void Sea Serpent, it seemed like there was still a battle going on there. Sect Master, do you want to go over and have a look?" Xiao Chu hesitated for a moment and asked.

Chen Gong went out this time, in addition to cultivating on the Sea of Nothingness, he also had a thought, that is, to find Qingmei and the others who had lived in seclusion on the small island of the Sea of Nothingness in the southwest of the Evil Horse Continent.

Speaking of Chen Gong and Qingmei's Baihuamen, the relationship is quite deep, but the relationship is complicated, he saved Qingmei, and was framed by Qingxue, chased and killed, but later Qingmei saved him, and the grievances are not so easy to explain.

In order to escape the pursuit of the purple-clothed messenger of the Sun Worship Sect, Chen Gong separated from the people of Baihuamen, and led away the purple-clothed messenger alone, and later fell into the eye of nothingness, and after countless life and death tribulations, he was lucky to be spread by the time and space in the eye of nothingness to the sea of nothingness in the east of Nanhuang County, and now he has the opportunity to revisit the old place, Chen Gong naturally hopes to find Qingmei and others.

Therefore, after going to sea from Nanhuang County, the route set by Chen Gong was to first go straight to the northeast, bypassing the sharp eastern corner of the Yanlong Empire's territory, and then turn to the northwest and head towards the sea area between the Central Continent and the Evil Horse Continent.

Now on the map obtained from the goblin clan's airship, it can be found that after three months of sailing, the extremely fast stealth ship has passed through the sharp horn of the fire dragon, and theoretically has entered the sea area between the central continent and the evil horse continent, that is to say, if you meet Qingmei and others here, it is not impossible.

"Turn on the invisibility function and go up and take a look. Chen Gong thought about it and said.
