It's a pity that the three of them watched for a long time, and the most of them on the ground were immortal crystal fragments, as well as a few pieces of tungsten iron essence, and they didn't see any trace of the black iron essence.

Their hearts suddenly sank to the bottom, Cheng Ling smiled bitterly, and was about to speak, but Zhou Qingxi behind him shouted in surprise: "Brother Jin, do you see if those shelves are refined by Xuantie Essence?"

Jin Muchen was stunned for a moment, then reacted again, and hurriedly rushed up and carefully observed those shelves.

Cheng Ling was also in high spirits, gathering his eyes, removing the dust covering the outside of the shelf, and seeing the materials inside, he shouted happily: "Yes, these should be Xuantie essence, I finally found it!"

The three of them were overjoyed, but soon, Zhou Qingxi said again: "But these shelves have been refined into finished products, how to extract the dark iron essence in them, this is a bit difficult." ”

This is not a joke, the dark iron essence is very hard, and if the ordinary earth fire wants to be refined, it is impossible to do it for more than ten years!

Cheng Ling smiled and said, "It's okay, I have a way, but I also ask the two of you to keep it secret for the juniors!"

After speaking, as soon as his right hand was flipped, a meteor-like flame appeared.

Jin Muchen and Zhou Qingxi were shocked, looked at the beating flame in his hand and said, "You..... You...... , you actually have the flame after nirvana. One, two, three golden apertures, or the third-level nirvana fire. You're incredible, boy!"

Cheng Ling smiled and said, "As a spirit pill grandmaster, if you don't have such a grade of flame, how can you refine the essence of herbs." This is an opportunity that the younger generation gets by chance, and it's not a big deal. ”

Jin Muchan's eyes widened, and he said angrily: "Why can't we meet such an opportunity!"

Cheng Ling laughed, ignored them, and directly sacrificed the meteor fire, and refined it on the spot. The third-level Nirvana Meteor is already an extremely precious treasure, so try to keep a low profile if you don't let people know about it!

As for these two elders, they have also experienced life and death together along the way, and they have some understanding of their hearts, so they should not publicize it.

With the help of Meteor Fire, refining the Dark Iron Essence is much faster. In less than three days, all the dark iron essence in several shelves had been refined, and a whole basin-sized mass was enough to repair the battleship's power system.

After the refining was completed, Cheng Ling said: "Two seniors, we won't break through the road ahead, and it is important to return to the base camp for now." ”

The two of them didn't think they were angry, Jin Muchen also glanced at him appreciatively, and said: "Yes, there is a give-and-take, no matter how good the opportunity is, it can't be obtained without a certain strength, and the future levels should be more difficult." Maybe when our cultivation is improved again, let's find out again! I don't know if we will be able to find the location of the ancient Xuanwu Star again next time. ”

His words were not groundless, and everyone in this trip accidentally entered the Ancient Xuanwu Star through the turbulence of the starry sky. As mentioned before, the starry sky turbulence is extremely unstable, I don't know when it will appear, and even if it does, I don't know where it will be rolled up, and it is basically impossible to find the ancient Xuanwu Star again.

The three of them said no more, and returned to the original passage at full speed.

Their cultivation had greatly improved, and their speed was much faster than before, and it only took ten days to rush back to the battleship.

The sergeants were already waiting by the battleship, looking at Cheng Ling holding a washbasin-sized liquid in both hands, Du Tong, who was responsible for repairing the battleship, greeted him and asked in surprise: "Cheng Dutong, did you really find it?"

"Yes, take it!

Fix the powertrain, we've been out of the base camp for too long, it's time to go back!"

Nadu Tong was overjoyed, and hurriedly took the melted dark iron essence in his hand, and beckoned the sergeant to step forward to repair it together.

After another month, the ship was finally repaired. Everyone couldn't wait to board it, urging the fangs to take off immediately.

Cheng Ling silently calculated in his heart, it took almost a month to find the Xuantie Essence and the time to come back, and it took another month to repair the battleship, so there were only ten months left, and the ten-year period was about to arrive!

He asked, "Fang, how much time will it take us to return to the base camp?"

Fang's face was not good-looking, and he kept controlling the battleship to take off with both hands, and when he flew up, he said helplessly: "We were caught up in the starry sky turbulence, and we have been far away from the previous course, I can only enter the location of the base camp now, and let the system calculate the distance by itself!"

Cheng Ling was shocked and hurriedly asked, "How long will it take to figure it out?"

"It should be soon!"

Cheng Ling was helpless, so she could only wait patiently on the side.

After about half an hour, the battleship's control system made a "tick" sound, and the fangs looked at it suddenly, and in an instant, his face changed!

Cheng Ling raised his heart to his throat and asked, "How is it? How long will it take to go back?"

Fangs smiled bitterly and said, "At the current rate, it will take at least fifty years to fly back to the base camp!"

"What! Fifty years!" Cheng Ling shouted, and Jin Muxi, Zhou Qingxi, Chu Tianheng, Ye Zhining and others on the side all looked over.

Looking at the puzzled eyes of several people, Fangfang could only say the time to return to the base camp again. In an instant, almost all the monks in the battleship were petrified!

For fifty years, just stay in the battleship, not to mention whether the energy of the battleship can be maintained, it will be suffocated!

Cheng Ling frowned and asked, "Is there any way?"

"Yes! But it's hard!"

"You say!"

"The current speed is the normal flight state of the battleship, and if you want to greatly reduce the time, you can only use space jumping. However, the space jump function has a huge demand for energy, and each jump almost consumes more than ten times the energy explosive power!"

"Let's not talk about whether we have so much energy, and even if we do, if we use the space jump function for a long time, I'm afraid that the power system will be damaged again, and it will be worth the loss. ”

Everyone frowned, and they couldn't think of a better way for a while. But after fifty years, when I returned to the base camp, the daylilies were cold, and no one could accept it.

Cheng Ling pondered for a long time, and then asked, "What is the approximate demand for an energy burst?"

Fang Fang explained: "One billion lower grade immortal crystals can almost support the warship to sail for a year, and a space jump can basically reach a year's sailing distance, so calculated, one jump is ten billion immortal crystals, and we can't support it at all!"

Cheng Ling smiled bitterly, tens of billions of low-grade immortal crystals, if the three thousand troops in front of him were all together, they might be able to satisfy a few jumps. But what's the use of this, it's just to reduce the sailing distance by a few years! Could it be that the time that he and the others grabbed in the Xuanwu Secret Realm will have to be returned to the way back?

I must not wait for fifty years, not to mention that Yang Hongqiu's head disease will continue to worsen, even if it has been nearly twenty years since he left the Canglan Continent.

What happened to the Wuxiang Sword Sect? Are Liu Qingyan, Xi Yan, Jian Yinghao, and other relatives and friends safe? I can't find a way to return to the Canglan Continent, relatives and friends on the Canglan Continent

(This chapter is not finished, please turn the page)

I can't come to the Star Realm, can't I see each other again in this life!

With a long sigh in his heart, he said, "You fly according to the original route first, and I'll go back to the guest room to find a way!"

With that, he left. Only three thousand troops remained, staring at each other, not knowing what to do!

Back in the guest room, Cheng Ling took out the wine jug from the ring, the energy contained in the wine jug was definitely no less than ten billion immortal crystals, but he couldn't take it out in front of everyone.

He took out the matching cups and carefully poured some into the glasses. A strong smell of alcohol suddenly spread in the room, and he placed a few bans to keep the smell of alcohol from dissipating for the time being.

At present, there is no other good way, but to see if these wines can provide the battleship with the energy to make space jumps.

After a moment, he left the room again and turned back to Fang, and said softly, "Fang, you put these in the fuel depot first and see if you can support the energy of the space jump." ”

Fangs were confused, because there was a ban, he only saw some wine in a small wine glass, which could also be comparable to tens of billions of immortal crystals? However, based on his trust in Cheng Ling, he still reached out and took it, and poured the wine into the energy tank.

In an instant, the entire energy gauge seemed to burst open, and the fangs were frightened, and they were busy controlling the battleship to make space jumps!

In less than a moment, the red dot representing the battleship in the star chart disappeared instantly, and after some time it appeared again. Fangs suddenly looked at the coordinates on the starry sky, and suddenly opened his mouth wide, unable to speak for a long time.

Cheng Ling asked anxiously: "How? Space jump has become? How far did you jump, my day, you are talking!"

Cheng Ling kept urging, but Fangs was like a puppet, standing stupidly and unable to say a word.

In less than a moment, there was a sudden "creaking" sound in the battleship, and the hull of the ship also produced a slight tremor. Only then did he come to his senses, and he pressed his hands on the console several times in a row before the hull gradually stabilized.

He turned his head and said in shock: "Cheng Ling, what was that small cup just now? Just this cup of energy battleship has completed the starry sky jump, and the distance spanned under one jump is five years, which is really incredible." ”

Cheng Ling was ecstatic, he couldn't imagine that the wine was really useful, and it spanned a distance of five years at one time, according to this view, the pot of wine in his hand could be rushed back to the base camp within a year.

He immediately said, "You follow me to the guest room, I still have that kind of fuel here." Without saying a word, he grabbed Fang's arm and walked towards his room.

When he got back to the room, he took out the flask again and poured some wine into the cup.

The rich smell of wine and fairy spirit emanated, and Fangfang finally understood what the cup was. He hurriedly stopped and said, "Cheng Ling, don't pour too much, in a span of 10,000 years at one time, the energy of the immortal spirit qi explosion is too strong, so the battleship will not be able to withstand it!"

Cheng Ling was stunned for a moment and asked, "How can this be, can't you return to the base camp in a short time?"

Fangs said: "That's not it, as long as the energy of half a glass of wine, you can jump for three years at a time, and then let the battleship run normally for a few months, so I believe that as long as it takes a year, you can basically return to the base camp." ”

Only then did Cheng Ling understand, and immediately took out many wine cups, and poured half of the wine into each wine cup, and poured more than 20 before stopping. With all this energy, he believed that the battleship would definitely be able to return to the base camp within a year!
