There is a large weapon refining workshop in Bao Mansion, which has a large number of high-end tool making and processing tools.

After Ye Fan arrived at Bao's mansion, Mr. Bao immediately started work and prepared to dig out three inlay grooves of the soul core of the beast emperor on the hilt of the mammoth sword.

"Mr. Bao, how long will it take to complete the construction?"

"Excavating grooves is simple, but it is a meticulous job to carve a large number of subtle runes on the grooves. It is a meticulous job. It will take three or five days to do it slowly!"

"Can I finish the processing within two days? I will use this knife in two days!"

"I'm afraid there's something troublesome in the second day! If my husband's eldest disciple is there and someone helps, it might be faster. Unfortunately, he took a big order to refine weapons and has not returned now and will not be back for several months."

"Old Master Bao, why not come down and help me! This will be faster."

"You know how to refine weapons, too?"

Mr. Bao was very surprised.

"I am also a weapon refining king. When Mr. Cao Wei refined this knife, I also helped to fight."

Ye Fan smiled.

"Okay!"

Mr. Bao agreed.

Ye Fan helped him. As a weapon refining king, his attainments in weapon refining are also very top-notch. He is just a little worse than the weapon refining king.

Bao Yuanjiang explained to Ye Fan while processing.

The most difficult part of inlaying grooves is that a large number of fine runes are carved inside and outside the grooves.

The material of the fifth-level imperial sword is extremely hard and requires great strength to carve a fine rune like a needle tip around the groove of the blade body, and thousands of runes form powerful runes.

If the force is insufficient, the runes cannot be carved out at all. However, if the force is too strong, it is easy to damage the subtle runes and engrave the wrong lines.

Of course, these subtle runes are engraved very shallowly and will not destroy the material of the blade.

In just two days, with the joint efforts of Bao Yuanjiang and Ye Fan, the three exquisite crystal core inlay grooves on the hilt of the Mammoth Emperor Sword were all made and processed.

Three fine runes spread from the grooves of the knife handle along the golden blade to the tip of the knife that was ten feet long. These mysterious runes add a stunning texture to the mammoth sword.

"You try to inlay the soul crystal into the groove!"

Bao Yuanjiang smiled.

Ye Fan nodded and took out a green spider mother's crystal core from the storage ring and embedded it in one of the crystal core grooves.

Soon, a faint green energy in the Beast King Crystal Core automatically overflowed, flowing into the groove, and then flowed along the runes to the blade.

This vitality is the vitality of the Green Spider Queen.

"Success!"

"There is actually a vital energy flowing out of the crystal nucleus? How did this be done?"

Ye Fan was surprised.

He had tried a lot of methods before, but he could not open the crystal core of the Green Spider Queen. This crystal core was extremely strong and indestructible.

"The principle of this crystal core groove actually imitates the structure of the beast king's flesh sac and connects it with the crystal core with a large number of vital energy patterns.

The crystal core was in the inlay groove, thinking that it had returned to the flesh sac, so it would automatically release a large amount of vitality so that the Beast King could release the beast talisman combat skills. Otherwise, under normal circumstances, the powerful power in the crystal core could not be used at all, and the Beast King's soul crystal core could not be opened."

Mr. Bao explained a few words and felt extremely satisfied with the mammoth sword he had processed. "I haven't processed the soul crystal inlay grooves for many years, but fortunately my hand is not unfamiliar!"

Ye Fan nodded slightly, held the mammoth sword in his hand, and waved it casually. After the blade was inlaid with crystal nuclei, it became much heavier, and other aspects were similar to before.

"How many combat skills can be used after inlaid with crystal cores? Can all Spider King beast skills be used?"

Ye Fan asked.

"This crystal core is the essence of the lifelong essence of the Green Spider Queen. All the talented beast skills mastered by the Green Spider Queen during her lifetime can be used. There are several specific types, just be sure to know about this yourself, and try not to disclose it to others. Using this knife to accidentally use the Spider Queen's beast skills, it can often have miraculous effects."

Bao Yuanjiang smiled.

Ye Fan nodded and paid a processing fee of up to nine million yuan.

Processing a soul crystal groove requires up to three million yuan stones.

A total of three grooves were processed, which could be regarded as a sky-high price that shocked King Wu.

Ye Fan didn't have so many stones on him.

He received all kinds of rare gifts from the Beast King in the dark forest, and sold almost all of them in the Hei Shui City, and then exchanged for such a huge fee.

But it's also very worth it.

Holding this mammoth sword with Spider Emperor Soul Crystal embedded in it allows him to release the beast king's beast skills, and his explosive combat power almost chases half of the beast king.

Ye Fan finished processing the mammoth sword before the great forces in Heishui Bay besieged Zhulong Mountain.

That night, he came to the Ghost Ship, met with the Ghost Queen and other ghost tribes, and prepared to go with him to Zhulong Mountain occupied by the Butcher Gang.

The Ghost Queen was wearing a black robe and holding a ghost staff in her hand. She was floating gracefully on the bow of the boat, and her cold eyes were indescribable.

The Skeleton King carried a larger hammer on his shoulder, like a war god several feet tall, guarding behind the Ghost Queen.

In addition, there are more than 500 well-trained elite skeleton ghost marquis and ghost ghost marquis, ready to go.

"I'm waiting for you, put on this!"

The Skeleton King threw Ye Fan a black ghost robe, and said in a hoarse voice.

This is a clothing that the ghost tribe often wears, and is contaminated with a strong ghost spirit.

"This is?"

Ye Fan took the ghost robe and was a little puzzled.

"You are now heading to Zhulong Mountain in the name of my emperor. It is best not to let people find out that you are a human race. After entering Zhulong Holy Cave, you may still have to fight with the human race. If you don't want to be regarded as a traitor by the human race in the future, please change into this ghost dress now!"

The Ghost Queen said lightly.

When Ye Fan heard this, he couldn't help but put on a ghost robe silently and enveloped his whole body in the ghost robe.

Although the ethnic groups in Heishui Bay are relatively peaceful and often make transactions with each other, there is still a clear distinction between the ethnic camps.

The power of the ghost clan is almost all the ghost clans, and the human gangs are usually human clans. For example, the Butcher Gang, the Tianlong Corps, etc., the top human forces in the Heishuiwan area are all human clans.

Unless they are rebels, they generally do not openly join the power teams of other races.

Although he only joined the Ghost Queen's side for a short time and did not really rebel, his reputation was not good when it was spread and it was easily regarded as a betrayal of the human race.

"Let's go and go!"
