The Zhang family's things may seem useless to others, but they make Lin Chen extremely happy.

"With fifty-three first-level terracotta tree seeds, my first-level terracotta tree can reach 180."

Lin Chen planted the seeds and then worked hard to water them with his talent. Unfortunately, in order to obtain more resources, the Zhang family did not leave a single sea figurine seed, which made Lin Chen slightly disappointed.

However, when he thought that he still had fifteen second-level terracotta tree seeds in his hands, Lin Chen's mood brightened again.

Not only the terracotta warrior seeds, there are also many second-level spiritual plant seeds in the storage bag, all of which are spiritual plants that can be continuously recycled. I think the reason why I chose these spiritual plants that can leave seeds is that I can use them to restore glory.

.

After reading the Ling Zhi Bag, Lin Chen picked up the second storage bag.

"Perhaps this is the most valuable thing." Looking at the storage bag in his hand, Lin Chen felt dumbfounded.

This storage bag should not be used as a family treasure.

"Eighteen kinds of third-level spiritual materials, plus more than a hundred kinds of second-level ores, are the Zhang family so confident that their ancestors can break through?"

Lin Chen was a little speechless. Logically speaking, these materials used to refine third-level magic weapons should be collected only when one is in the Purple Mansion Realm.

Unexpectedly, the Zhang family's "predictor" had already seen the situation of his ancestor Zifu, and was so ready.

In fact, this was Lin Chen's misunderstanding. The Zhang family prepared these third-level spiritual materials so that their ancestors could protect themselves.

If the three Zifus in the Jingzhe Sea Area knew that a Zifu had appeared on Jingzhe Island, they would definitely find a way to attack and kill them when they first entered. If their ancestors had a magical weapon, it would be easy to deal with them.

Putting down the things that he didn't know when he would use, Lin Chen looked at the third bag.

This bag contains jade slips collected or made by the Zhang family, which contain a large amount of knowledge on martial arts and various cultivation techniques.

"These things can be placed in the Yujing Tower in the future." After saying that, Lin Chen reluctantly took out the jade slips about formations.

A few hours later, Lin Chen gained a lot more knowledge about formations, but other than that, he gained nothing else.

"Is the formation talent really that bad?" Lin Chen's eyes twitched a little, and he wanted to crush the jade slip in his hand into powder.

After struggling for a long time, Lin Chen stuffed it back into the storage bag out of sight and out of mind, and looked at the fourth storage bag.

After looking at the first three bags, he had already guessed what they contained.

Sure enough, Lin Chen was extremely excited after taking out a jade slip and hundreds of scrolls from his storage bag.

"How to refine Douhai-class warships."

Lin Chen rubbed his hands. The Douhai-class warship is a warship corresponding to the True Yuan realm, and it belongs to the same level as the floating-class airship among flying boats.

He had long been curious about warships, and how powerful these warships forged from the carcasses of sea beasts were.

After being obsessed with it for more than half a month, Lin Chen opened his eyes with complicated expressions.

For more than half a month, under intense concentration, even his extraordinary mental strength was somewhat exhausted.

The information in the jade slips is an outline of how to connect each of the warship's accessories to make them a whole.

And those scrolls are the refining and forging methods of each part of the warship.

A warship requires a lot of first-level ores, and after refining the spiritual iron, the parts between the embryo and the magic weapon are forged.

Then there is the need for spiritual wood to be used as the outer contour to reduce the weight of the warship.

But to Lin Chen's chagrin, the method on the spirit tree that could reduce the weight of the warship was the formation...

However, he had already guessed that the various array disks produced by the Lin family were made with spirit wood as the core.

"It seems that it is difficult for one person to forge a warship."

A warship requires at least tens of thousands of quasi-magical weapon parts. Although refining is easy, refining the weapon itself is a very time-consuming task.

For example, Lin Chen spent most of his time in the cave refining elixirs and making talismans because these two things took up too little time in comparison.

Among the hundreds of scrolls, these scattered parts account for the majority, but they are obviously the lowest value.

After all, the remaining small part of the scroll records the forging method of sea beasts.

"Continuously burn the corpse of the giant sea beast with spiritual fire until the spiritual blood is completely attached to the skeleton, and then use the weapon refining method to refine a complete warship core, which is the keel."

"Basically, a warship half the size can be made from any giant sea beast."

Lin Chen pondered, the method of refining the keel seemed easy, but in fact it was the greatest test for the weapon refiner, and it was also the most dangerous part of warship refining.

To completely forge a sea beast, not only does the craftsman need to possess powerful spiritual power, but he also needs to withstand the pressure of the true essence state of the entire giant sea beast.

Once the weapon refiner cannot hold down this dead body, it may even affect the weapon refiner himself.

Being unable to suppress it means that he will not be the opponent of the sea beast when it is alive and is in a state of absolute suppression. The backlash in this situation will inevitably severely damage the weapon refiner and completely fail the warship refinement.

Lin Chen guessed that when the families on Jingzhe Island refine a dragon bone, they must have at least three or five True Yuan realm monks assisting them.

After all, under normal circumstances, those who are passable in the various arts of cultivation will not have very high combat effectiveness.

Of course, this situation will be reversed as your cultivation level increases.

After understanding the warship, Lin Chen also understood the key to the warship being able to sail on the sea.

Firstly, the aura of the monks on the ship made the creatures in the sea afraid to commit minor offences. Secondly, the pressure of the giant sea beast carried in the keel of the warship made the monsters in the ocean frightened.

The most important thing is that the warships forged from the corpses of sea beasts belong to the sea to a certain extent, so that the powers in the deep sea will not attack them as outsiders.

After all, the ocean is not a place where humans are unscrupulous.

Lin Chen collected the jade slips and scrolls and placed them on the spiritual wood shelf in the corner of the palace. There were already many such shelves in the palace.

Various pieces of knowledge that Lin Chen had collected over the years were scattered here and there.

Although he didn't know what the palace was used for, Lin Chen transformed it into a Tibetan Dharma Palace.

"The matter of the warship is not urgent. It will be ready after Jingzhe Island is captured. The top priority is still the issue of Jingzhe Island."

He took another look at the Blood Forged Maple Tree and found that Lin Chen left the cave after almost completing the breakthrough.

One day later, Lin Chen took Zhang Buhuan to a valley.

"Is this where the Lu family is hiding?"

Looking at the unremarkable valley in front of him, Lin Chen felt a little doubtful.

"Yes, they have more people alive than us. This is one of their hiding places and the only location open to the public."
