Dugu Ling Yu's words attracted the attention of many people, including Neimen Zhu Er and Huangfu Yi, this time in the Shenhou Secret Realm, several people ran in very well, and they would also form a team to conduct the trial in the seven-day trial.

Liu Zhiji couldn't help but be interested in the people below forming a team on his own, two of which made him very optimistic, one was the elite team headed by Zhu Erhuangfu Yi, these two teams in addition to the two of them also have Zhuang Shiyi, Dugu Lingyu and Jian Twenty-three, and the other is Zheng Bufan and Zhang Hongyu, Hou Sai and Uncle Zhang, plus Zhan Xiaozhao a light bulb, this team is even stronger, Liu Zhiji knows that if it is an irregular melee, the elite team is not their opponent.

Liu Zheji saw his old friends again, Huangfu Yingjie, Jiang Nishang and Lei Jue, they also formed a team, and to his surprise, Zou Qingshui and A Ning didn't know when they got mixed up.

"This group of people... Abandoned me. Liu Zhiji smiled bitterly.

In fact, Liu Zheji wanted to go down to participate in the trial in person, but it was impossible with his current identity.

Seven days of trial, nothing can be decided in a short time, Liu Zhiji decided to go to the ghost domain mine first, the ghost domain mine developed by Zhang Sihai has always been a mystery, and I don't know how long it will take to collect resources.

Ancestor Moyun and Elder Meng happened to be fine, and Liu Zhiji and the two flew to the back mountain mine road together.

When the three of them came here, Zhang Sihai and Zheng Yuanying had been waiting for a long time.

"Mansion Master, the Ghost Domain Mine has been initially opened with the support of Zhongxu Hall, now let me take you to see the situation inside. Zhang Sihai led the way into the mine.

After descending to the mine, Liu Zhiji was shocked by the scene below, the entire mine tunnel below was very wide, and there were two passages from the bottom of the mine.

"This is a backup passage, where we are now is the main passage, the rock wall around the mine is using the new technology of Tiangongtang, you see that there is no support in the mine, which greatly increases the space of the mine. ”

Liu Zheji looked around, the mine was cylindrical, and there were two rows of machine lights on the ceiling that were glowing dimly.

"Open the gates!"

Zhang Sihai instructed the martial artist next to him, and after a while, the entire mine road was completely lit up, and the original dim machine lights became extremely bright.

"This lamp was researched by the tyrants, to be precise, they have developed a magical circuit that can be connected to the spirit gathering formation, so that the machine lamp can use the aura of the outside world to illuminate the entire mine. ”

"The line, is it connected to the Spirit Gathering Array?" Elder Meng and Mo Yun Ancestor glanced at each other, and they both saw shock in each other's eyes.

Liu Zhiji nodded, the tyrant should not waste any effort to develop this thing, those puppets have the function of gathering spirits, and they can be done with a little conversion.

A large trapped minecart appears in the mine, which looks like a sealed iron box and rumbles as it approaches from a distance.

When the minecart stopped in front of everyone, the tyrant, Zhang Hongyu and others jumped out of the car.

"Young master, how is it?Is the minecart I invented handsome?" the tyrant pointed to the minecart with a smug face, and then everyone noticed three big words on the cart.

"The Tyrant?"

Liu Zhiji looked at the tyrant in surprise.

"That's right! This is the first self-propelled minecart of the Tyrant that I built! The car does not need to be instilled with aura at all, it only needs ordinary people to operate, and the control is very simple. ”

The tyrant introduced everyone into the car, the space in the minecart is not very large, two rows of seats can seat about a few hundred people, this minecart does not seat many people, except for Zhang Hongyu and other middle-level cadres, it is Liu Zhiji them.

"The full speed of the Tyrant is about half the speed of the Realm Warrior's full flight, and it can run infinitely as long as the aura is enough!" the Tyrant continued.

"The Tyrant does bring us a lot of convenience, there is still a distance from the Ghost Domain Mine, it takes two days for ordinary warriors to go back and forth in the mine, and it only takes two hours to have the Tyrant. Zhang Hongyu also said on the side.

Liu Zhiji nodded, he and Elder Meng looked around the Tyrant several times, Liu Zhiji carefully felt it with his soul, and felt that this minecart was promising.

"If the energy is produced, then solving the problem of reiki replenishment may be able to sell it for a good price. Elder Meng rubbed his chin and said.

"Why sell? This is something I've worked out with great difficulty, not to mention who will buy this thing if it's sold. The tyrant's eyes flashed red, and he said angrily.

"This thing may be a stepping stone for us to set foot in Zhongzhou, you think about it, even the traffic in various places in Zhongzhou is definitely not convenient, and everyone will fly, right? If we lay a mine road in a certain place and get some mine carts, we must be able to earn a lot of spirit stones, right? Of course, the most important thing is not the number of spirit stones, but that our Zichen Mansion must rely on it to enhance its influence!"

Elder Meng's words made everyone think in silence, and Liu Zhiji was also surprised by Elder Meng's idea in his heart, this is indeed the capital for them to step into Zhongzhou, to be honest, their Zichen Mansion wants to gain a foothold in Zhongzhou, first of all, the strength is not good, then they can only make up for it from somewhere else, Liu Zhiji's original idea was to plant, but planting is a small road after all, how can such a thing as spiritual tea be as profitable as munitions?

"But... I also have to study the issue of anti-theft, in case it is copied by someone else after selling, it is equivalent to giving someone a chance. The tyrant was also persuaded by Elder Meng, and he suddenly didn't want to go to the Ghost Domain Mine with Liu Zhiji and them.

"Let's go and research, we need more mature products now, and we can be notified when we have a sample. Liu Zhiji saw the tyrant's hesitation and said directly.

"Received the young master!" the tyrant retreated happily after receiving the order.

Zhang Sihai and Zheng Yuanying glanced at each other, both of them were a little embarrassed, this Tyrant had been running for nearly a month, and they didn't find that the Tyrant still had such a future.

Liu Zheji glanced at the two of them and said directly: "Senior Zhang, your focus is different, it's normal not to see it, I didn't think of it just now, so don't feel guilty, by the way!

"Let's go!" Zhang Hongyu glanced at his subordinates, and the other party understood, and immediately launched the "Tyrant".

"Yuan Ying and I experimented with the ancient formula I got, and the results were not very ideal at first, if you completely abandon the yin qi of the ghost cut grass, the ghost cut grass will contain very little aura, so many ghost cut grass is the harvest of a super ore vein, but then we have practiced several times, and found that as long as the lethal amount of the ghost cut grass is controlled just right,

Then a ghost cutting grass will bring three times the amount of spiritual energy of the ghost cutting grass that completely abandons the yin qi!" After Zhang Sihai finished speaking, he nodded at Zheng Yuanying and motioned for him to say the next.

Zheng Yuanying didn't give in, and said directly: "We have experimented hundreds of times, and by chance we discovered that Yin Qi Dispersion can remove the Yin Qi of the ghost cutting grass!"

"It's good that Yin Qi Dispersion can remove Yin Qi, but it can only remove a little bit, right?" Elder Meng frowned, he obviously knew the effect of Yin Qi Dispersion.

Zheng Yuanying nodded, "That's right! Yin Qi Scatter can only remove a little bit of Yin Qi! But Yin Qi Scatter can be reused, as long as you take a large amount of Yin Qi Scatter, you can completely remove the Yin Qi of the ghost cutting grass!"

"Oh?" Elder Meng didn't know this, and he didn't usually need a low-grade medicine like Yin Qi Dispersion.

"So now we can use the Oni Grass Cut?" asked Yanagi Ori.

"That's right! This time I went to investigate, first, to check the number of ghost grass cut in the ghost domain mine, and second, to search the ghost domain mine again to see if there was any omission in it. Zhang Sihai set his eyes in the direction of the Ghost Domain Mine.

"There are still some areas in the pit that we haven't excavated, so maybe it will give us some extra surprises. ”

The Tyrant had been driving for an hour, and the temperature around it had dropped sharply, and Liu Zhiji could already feel that there were Yin Qi ghosts looming outside the minecart.

"There is an evil warding array set up by Elder Gongsun Yan on the Tyrant, and the general yin evil will be blocked out. Zhang Hongyu couldn't help but remind when he saw Liu Zheji's expression.

"Hmm. Liu Zhiji nodded, he was not worried about the yin evil outside the car, but he felt a trace of discomfort in the dark, but the surrounding Elder Meng did not show this abnormality, and Liu Zhiji could only press this throbbing in his heart.

The Tyrant was docked at a slightly higher location, a large garrison, and the Tyrant's doors fit into the side doors of the garrison.

The car door opened, and they walked out, and the disciples who had already greeted them saluted a few people.

"They're going back, aren't they? Let them go first, everyone's worked hard. Liu Zhiji looked at these disciples with a smile, and these warriors all had heartfelt admiration and excitement on their faces, and Liu Zhiji was also touched.

"In the future, you must move forward steadily every step in the future, and you must not rush forward!" Liu Zhiji secretly said to himself, he is not a person now, the decisions he makes will affect the life and death of the entire Zichen Mansion, and he must be extremely careful with every step he takes in the future.

"The entrance to the Ghost Mine is just ahead, and we have set up a gathering point here, there are a total of three mines leading to the Ghost Mine Pit, and now we are about to enter the first one. At this time, Zhang Hongyu took out several sets of strange-looking "armor" from the storage ring and put them on in front of everyone.

"They are all engraved with small evil circles that can block yin qi and evil spirits from contaminating the soul. Facing everyone's surprised eyes, Zhang Hongyu said with some embarrassment.

Liu, they naturally don't need to put on these things, they are all realm-level martial artists, and a mere yin qi can't hurt them.

"This time, we will take the third alternate passage, this passage will send us to the center of the ghost mine, everyone get ready, there may be ghosts in the center. Zhang Sihai nodded to Zhang Hongyu and signaled that he could open the passage.
