Chapter 352: Sky Patrol

After two years of hard work, Chen Qingyan has made significant progress.

Her cultivation has broken through to the late stage of foundation building, and her refining attainments have also improved, reaching the second-level middle grade.

At the same time, she practices the "Great Sun Visualization Sutra" to temper her soul every day, and the strength of her soul is comparable to that of a cultivator in the late stage of foundation building.

Continuing to practice this technique will not only enhance her strength, but will also make it easier to open up the Purple Mansion in the future.

Chen Qingyan was once injured by a water toad beast on Xiaozhu Island, causing damage to her Taoist body and her cultivation to regress to the second level of Qi Refining.

Now more than ten years have passed, not only has her cultivation recovered, but she has also advanced to the foundation building stage. The progress in the past ten years is not small.

This makes her have great expectations for opening up the Purple Mansion, hoping to catch up with Chen Qingyun's pace.

At least, don't drag Qingyun's feet.

While paying attention to the progress of the fifth sister, Chen Qingyun guides Chen Qingluan in her practice in her spare time.

It must be said that Chen Qingluan has made rapid progress.

With the talent of the heavenly spiritual root, the innate Dao body, the essence of the spiritual wood, and the assistance of various resources, her cultivation is simply advancing by leaps and bounds.

From the original fourth level of Qi Refining, she broke through to the seventh level of Qi Refining.

Now, under the guidance of Chen Qingyun, she began to learn the way of refining instruments, and she learned very quickly.

Xiao Qingluan's progress made Chen Xianming and others dumbfounded, and they felt that excellent talent is good!

At the age of fifteen, Qi Refining Seventh Level, this would be regarded as a peerless genius in Xingzong and worshipped as a treasure.

Chen Qingluan is not only the treasure in Chen Qingyun's hands, but also the jewel in the palm of the Chen family and the pillar of the future.

The next candidate for foundation building is probably Chen Qingluan.

It is worth mentioning that the Chen family still has foundation building pills.

At the end of the war, the Chen family exchanged five foundation building pills from Xingzong, and three of them were collected.

Due to the shortage of foundation building pills, the other two need to be refined by Xingzong for the time being and supplied to many cultivators.

Therefore, the Star Clan has always owed the Chen family these two pills.

Fortunately, the Star Clan fulfilled its promise.

The Star Clan sent a foundation-building cultivator to escort the two foundation-building pills owed, and personally visited the Chen family and handed them to Chen Xianming.

For now, the two foundation-building pills are temporarily sealed in the clan vault.

There is no one in the family who meets the foundation-building requirements.

Moreover, the cultivators of the Chen family can practice the "Great Wilderness Devouring Demon Art" to build the foundation, and the resources required are about the same as a foundation-building pill.

It can be said that both ways are safe to build the foundation with the art or the foundation-building pill.

In addition, the red sun fruit tree, the spiritual peach tree, and the spiritual apricot tree exchanged from the Star Clan have grown up and each has produced two spiritual fruits.

These spiritual fruits are of great benefit to Qi-refining cultivators, and can improve their cultivation and widen the gap with other cultivators of the same age from other races.

Another point is the six-headed seahorse presented by the Xu family.

After more than three years of domestication, it has become a family spirit beast. Five seahorse cubs were born and began to work for the family, transporting supplies to Heiyafang City and Yishi Island.

Here, Chen Qingyun thought about the family, and the family did not treat him unfairly.

After more than three years of mining the white stone veins and trading with Lingbao Mountain, the Chen family earned more than 400,000 spiritual stones in pure profit.

For this reason, Chen Xianming convened a family meeting and buried 100,000 spiritual stones directly under the ground of Zhenhai Island.

For cultivating spiritual veins on Zhenhai Island, none of the family cultivators objected.

Chen Qingyun's kindness to them, sharing skills and giving away magic tools, Chen Daolin and others remembered them one by one.

Knowing that Chen Xianming was going to cultivate artificial spiritual veins on Zhenhai Island, let alone the family's wealth, if they really needed some spiritual stones, everyone would raise their arms and pay for them out of their own pockets.

Now, 100,000 spiritual stones have been buried for more than a year.

According to this progress, in two years at most, the first spiritual vein will be born on Zhenhai Island.

Just look forward to it.

Let's get back to the topic and talk about Chen Qingyun.

Because he often hunts monsters in the sea and practices "Great Wilderness Devouring Monsters" in his spare time, Chen Qingyun's strength has reached a bottleneck. He is only one step away from the peak of the Purple Mansion and may break through the shackles at any time.

The weapon refining technique has also improved, and it has been upgraded by one grade to the third grade middle grade.

This level of weapon refiner is in the top ten in Lingbao Mountain, and is particularly popular in the star sea.

Because of this, relying on his weapon refining attainments, Chen Qingyun has made breakthrough progress in shipbuilding in the past two years.

He once only modified a Panlong, equipped with a demon-killing cannon and a Tianji mirror to enhance its power.

Now, not only have two demon-killing cannons been added to the Panlong, but also a flying effect has been added, which can be transformed into a flying boat to gallop across the blue sky.

In addition, Chen Qingyun built two more warships.

These two warships were built according to the spirit ship formula and were uniformly modified. Each of them was equipped with three top-level demon-killing cannons and a Tianji mirror, which gave them the ability to fly and became sea and air amphibious weapons.

These two warships were huge and reached the level of top-grade magic weapons. Chen Qingyun named them patrol ships.

A patrol ship can easily kill the peak creatures of the Purple Mansion, and can also command the five elements puppets to control it.

With the Panlong, it can form a fully automated small fleet.

The Panlong is equivalent to the prototype of an aircraft carrier.

"We have three warships. The next step is to arrange drones. We can't just fight according to the detection range of the Tianji mirror. In this case, the combat radius is not large."

Chen Qingyun began to tinker with drone manufacturing.

The paper crane recipe that I bought from Chen Mengru at the beginning is the basic version of the drone.

There are two kinds of materials needed to refine this first-grade medium-quality magic weapon, namely Xuanyu Crystal and Void Wood.

These two materials are not of high grade, both of which are first-grade medium-quality, but it is not easy to buy them.

In order to gather these two materials, Chen Qingyun went to more than a dozen markets in the inner and outer star seas and collected some of them in bits and pieces.

There were a total of 19 refining materials. Chen Qingyun summoned the Qingyou Sky Fire and immersed himself in the refining process.

After a day and a night, nine paper cranes were finally refined. Each one was about the size of a person. It was light to hold, as if it could float in the air as soon as you let go.

"Nine paper cranes, it's just right to fuse three."

Chen Qingyun exhaled a breath of turbid air, took a blood and qi pill, and replenished the consumed mana.

"But the strength of this paper crane is still lacking. Just like strengthening the Qingyan Sword, we need to add fire-refined gold to improve its strength."

"In terms of attack power, we also need to think of a way to increase their firepower output so that they can have self-protection and attack capabilities."

Chen Qingyun thought for a while.

It is very simple to strengthen the toughness and firmness of the paper crane.

When I was in the Wonderful Equipment Pavilion, I specially purchased a batch of fire-refined gold and Kunmu Stone.

These two materials can achieve the effect of strengthening the magic weapon.

As for giving attack power.

Since the paper crane has no attack power and defense power, it is a very useless magic weapon with limited scope of application.

For Chen Qingyun, since it is used as a drone, it must not just fly and not attack any enemy.

It must be given some attack power.

Equip the Demon-Slaying Cannon, but it is not suitable. That thing is too big to fit the paper crane, and it will not let the paper crane fly.

So, we have to find some lightweight weapons.

Chen Qingyun selected from more than a hundred prescriptions and finally found a solution.
