Back mountain, refining workshop.

In the huge hall, there is a topaz spirit boat suspended in the middle.

Zhang Ling stood beside Master Chen Jing and observed the flying boat, the topaz spirit boat was more than four zhang long, and the style was simple to perfunctory.

In his god's eyes, there was a dazzling phosgene inside the flying boat, and wisps of phosgene were constantly escaping from the light cluster, which was completely different from other spirit boats.

Chen Jing raised his hand and said, "This is the Spirit Boat powered by the Chaos Yuan Qi Furnace, which was just built a few days ago. ”

The idea of using the aura produced by the gourd to drive the spirit boat can be put forward by anyone, but it is not easy to do.

The aura emitted by the gourd is very chaotic and violent, and it cannot directly drive the magic circle, but must be transformed into a stable and controllable aura.

Chen Jing designed the Chaos Vitality Furnace to solve this problem, and he spent a lot of time and energy on it, doing a lot of tests, studying a series of problems such as the Chaos Vitality Furnace's aura output, vitality transformation, materials used, and refining techniques.

The spiritual energy output of the Yuan Qi furnace in the spirit boat is stable and controllable, and the volume and weight are not large, which can be practical.

The flying boat can be driven by the mana of the immortal cultivator, and it can also be driven by spirit stones, and it can also be used to gather spiritual energy as a power like a mountain-moving cloud boat.

Now if you want to use the Chaos Vitality Furnace to drive the Spirit Boat, the part that receives the Spiritual Qi has to be changed, and it is not easy to do.

"Does it fly fast?" Zhang Ling stared at Lingzhou and asked excitedly.

"I haven't tried it yet." Chen Jing said that the main purpose of building this spirit boat was to verify the feasibility, and now that the spirit boat was suspended in mid-air with the spiritual energy output from the Chaos Yuan Qi Furnace, it could be said that the experiment had been successful.

Seeing that Zhang Ling was eager to try, Chen Jing said: "Let's take it out and try it." ”

As he spoke, he threw out a green-skinned gourd and put away the spirit boat.

This spirit boat is very large, and it should be loaded with a Qiankun gourd.

Zhang Ling looked at the Qiankun gourd, and had some expectations, in more than ten years, the Qiankun gourd in the courtyard will be mature, and there must be one when the time comes.

The master and apprentice took the spirit boat out of the refining workshop, Chen Jing released the spirit boat, and the two floated up.

Chen Jing took out a jade plaque and said, "Use this control." ”

The topaz spirit boat rose and flew into the blue sky.

Chen Jing flew around the Lingzhou and tried out the speed, balance, steering and other properties.

Feeling so-so, seeing that Zhang Ling also wanted to try it, he took out a piece of spiritual jade, ignited a flame in his hand, and refined a jade plate in a few breaths.

"It's ready to be used after a sacrifice." Chen Jing threw the jade plaque to Zhang Ling.

"Good!" Zhang Ling took the jade plaque, this was just a very simple magic weapon, and he refined the jade plaque in a blink of an eye.

Chen Jing let go of control, and Zhang Ling controlled the spirit boat to fly.

It feels like it only needs to be controlled, and it doesn't consume aura at all.

The speed of the spirit boat is between the magic weapon and the magic weapon in the late stage of foundation building, which is not very fast, but it does not consume mana at all.

Zhang Ling said excitedly: "As long as there is a jade plate, the Qi Refining Period cultivators can control this spirit boat. ”

"That's right! That's one of its great things. Chen Jing was a little complacent.

It is very difficult for a Qi Refining Period monk to fly, and an ordinary Floating Cloud Gourd can only be used by a Foundation Building Monk, and the power of this spirit boat is provided by the Chaos Yuan Qi Furnace, and the Qi Refining Period Monk can control it like a jade medal.

The flying boat continues to improve, and in the future, it will be able to reach the speed of the flying magic weapon, which means that the monks in the Qi refining period can also drive the spirit boat to reach the speed of the Jiedan monks.

Of course, this spirit boat is not for Qi refining period cultivators, the speed of the spirit boat is fast, even if it doesn't need mana, it also needs a quick reaction and strong control, which these Qi refining period cultivators don't have.

There were several precious gourds in the Chaos Yuan Qi Furnace, and the Qi Refining Stage cultivators couldn't afford to use them at all.

"Lingzhou is still small." Zhang Ling said.

"Yes, the spirit boat is bigger, and the more melons it contains, the more powerful it becomes." Chen Jing looked into the distance and said, "There are more melons, not only do they fly faster, but they also have a more solid defense, a more powerful attack, and they don't need to consume their own mana." ”

"That's a war fort." Zhang Ling remembered the heaven-level battle castle of the Demon Suppression Palace.

"If you only think about fighting, you don't need to be the size of a battle fort." Chen Jing said that the most important reason why the battle castle was so big was that it was necessary to arrange a large enough magic circle to gather spiritual energy, and the space required for the Chaos Yuan Qi Furnace was much smaller than that of the magic circle.

"Hmm." Zhang Ling nodded, and then asked, "Master, what are you going to do next?" ”

"Research the more powerful Chaos Vitality Furnace, as well as the magic circle for receiving and blending aura." Chen Jing said, "The aura output of this Chaos Yuan Qi Furnace is still less. ”

He took out a jade slip and gave it to Zhang Ling: "Here are some of the studies I did, you can take a look." ”

"Good!"

Next, Zhang Ling practiced while following Chen Jing to do research.

In the evening, the atmosphere in the pavilion was warm, and now the disciples are all on the mountain, and there are more people.

Liu Fei'er took the spirit rhino and talked to Shen Congxue, Shen Congxue and Wei Chaoyu had already arrived at Juxing Mountain.

After a long time, Liu Fei'er put down the spirit rhino and said to Chen Jing: "Senior Sister Shen and Senior Sister Wei went to Demon Slayer City. ”

Chen Jing nodded and said, "Well, there are more sword cultivators there, and Haihong Zhenjun is in Demon Slayer City." ”

Speaking of Demon Slayer City, Zhang Ling and Su Caiyun lived there, and Liu Fei'er called them over and asked about the situation in Demon Slayer City.

"By the way, I haven't been in contact with Senior Sister Yin for a long time." She remembered the Yin Rakshasa in the Demon Slayer City before, and took out the spirit rhino to leave a message for this friend.

It is said that this year is the twenty-twenty-seventh year since the three masters and apprentices returned to Lingyan Mountain, and it has been more than one hundred and forty years since the two brothers and sisters returned to the mountain from the Fallen Demon Abyss.

Back then, the Yin Rakshasa was in the middle stage of the Jiedan realm on Juxing Mountain, and soon after returning to the mountain, he broke through to the late stage of the Jiedan, and now he has formed a Yuanying and become an elder of the Xuanyin Sect.

Now there is a communication network, and the message transmission is convenient, Chen Jing and Liu Fei'er met many Yuchen elites in Juxing Mountain, and knew the recent situation of some of them through the Internet.

Except for the Yin Rakshasas, most of the others have also practiced smoothly over the years.

Chen Jing secretly pondered to himself, the statement that hunting demons would increase luck should be reliable.

After dinner, everyone went downstairs to take a walk in the courtyard, after the renovation of the cave mansion, it was much bigger, and Chen Jing planted some star sand gourds.

He walked briskly through the large field of melon vines to the crystal trellis on the side of the courtyard.

In a flash, Xiao Luo followed, and only Chen Jing and Xiao Hua Demon could enter this flower shed.

In the crystal vase, the jasper broken branches shimmered, and although they were only half a leaf, they looked vibrant.

Chen Jing couldn't help but smile on his face, took out the jade gourd and dripped the jade dew into the vase, and performed another Wanmu Spring Trick.

A thick green mist of light shrouded the broken branches, and at the bottom of the broken branches, several tiny whitish protrusions grew on the part that was immersed in the crystal bottle.

It's the roots that have just grown, and the broken branches have finally taken root.
