The injuries caused by those demon-level powerhouses to demon-level powerhouses can recover quickly. However, the injuries caused by demon-level powerhouses to each other are not so simple to recover.

Although the demon-level corpse armor earthworm killed the demon-level rhino skeleton monster with the help of Shu Feng, he was also seriously injured and needed to recover.

Three hours later, the demon-level corpse armor earthworm was nourished by the high source energy of the source energy evolution tower and was summoned again by Shu Feng.

Shu Feng also recovered his full strength in the Source Energy Evolution Tower, and then he walked carefully towards the big city under the escort of the demon-level corpse armor.

As soon as he entered the big city, Shu Feng saw many human and human-like demon skeletons. He directly put all the demon skeletons into the base space.

The skeletons of those demon gods are extremely hard and are top-level materials that can be used to synthesize powerful synthetic beasts. In addition, the skeletons of those demon gods basically come with a trace of the source of the demon god.

Shu Feng collected more than 10,000 demon god skeletons along the way, and the number of demon god sources in his hand also exceeded 0 units. This is equivalent to the harvest of killing 0 demon god-level powerful men.

"Yes, these demon skeletons alone are a huge gain. They can make up for my consumption of synthesising demon-level corpse armor earthworms."

Shu Feng happily collected the skeletons of the demon gods, his eyes full of joy.

A hint of doubt flashed in Shu Feng's eyes: "However, why are there no demon-level secret treasures here? Unless the demon-level secret treasures have been destroyed by others, they should exist even in the past few hundred million years."

The physical fitness of the human race is far inferior to other races. Shu Feng practiced the supreme demon body and after transforming, he was infinitely close to the top ancient demons. That was the result of his consumption of resources like mountains and seas. Even so, his physical fitness may not be as good as the top legitimate sons of those ancient demons.

However, the human race's strong people are proficient in refining various secret treasures. With the blessing of various powerful secret treasures and secret techniques, the human race can compete with other races without losing the upper hand.

Since this is a human battlefield, in theory, there should be countless demon-level secret treasures or demon-level secret treasure fragments.

In the virtual and demon world, in addition to the true demon-level secret treasures, even the powerful secret treasures will slowly disappear with the passage of time.

If there is no special seal for the Demon King-level secret treasure, all the extraordinary powers in millions of years will generally disappear. The Demon God-level secret treasures can generally support hundreds of millions of years. The powerful secret treasures can support tens of billions of years before they will disappear.

Shu Feng shuttled through the ruins, searching for rooms after rooms, but found countless bones, but did not find any valuable treasures.

"Finally found!"

Shufeng's eyes lit up in the hall.

In the hall, there are dozens of inherited jade monuments, and a headless skeleton wearing a blue brocade robe kneeled on the ground.

The upper half of the dozens of inherited jade monuments had been cut off by a sword light, losing the power of inheritance.

"This time, I made a lot of money!!"

Shu Feng looked at the dozens of inherited jade monuments, and his eyes flashed with excitement.

Although the dozens of inheritance jade monuments have lost their inheritance power, the demon-level inheritance on them has disappeared. However, they are treasures with countless high-level source energy.

Shu Feng thought about it, and the demon-level corpse-eating earthworm immediately rushed towards the headless skeleton wearing a blue brocade robe.

The demon-level corpse armor with earthworm skin is thick and thick, and its recovery power is strong. Shu Feng will let him test it first.

Bang!

The headless skeleton wearing a blue brocade robe was hit by the corpse-eating earthworm and fell to the ground.

Shu Feng speculated in his heart: "There is no backup plan! It seems that this guy was directly erased. He was able to cut a big city with many demons guarding with one sword. The one who took action against this big city should be a top-level demon god."

If a powerful man takes action against this big city, the sword mark will definitely be covered with the power of a powerful man. If there is no external force, it will not disappear even for hundreds of millions of years.

Shu Feng stretched out his hand and the blue brocade robe on the headless skeleton flew into his hands.

"This is also a demon-level secret treasure! However, many places have been damaged and cannot compare to the real demon-level secret treasure."

Shu Feng looked at the blue brocade robe carefully, and a hint of joy flashed in his eyes.

A demon-level defensive secret treasure can make Shu Feng's defense more powerful. Although this demon-level secret treasure is already ruined, Shu Feng can use the source of the demon and high-level source energy to repair this treasure.

Shu Feng observed carefully for a while and found no abnormal movements. Then he stepped forward and put dozens of inherited jade monuments directly into the resource dissolution pool in the base space.

Countless dazzling brilliances shine, and the inheritance jade monument was directly dissolved on one side. Various mysterious inheritance knowledge emerged one after another and was absorbed by the database of the base space.

"There are also demon-level inheritances in these inheritance jade monuments! There are also demon-level inheritances in the great demon-level inheritances, but unfortunately they are all broken. They can only enrich the database of the base space."

"But this time it's a great harvest!!"

Shu Feng's eyes fell on the resource data of the base space, and his eyes flashed with ecstasy. The dozens of inherited jade monuments added a total of 2.3 billion high-level source energy to him, which was equivalent to his search for another ghost world.

"Repair this demon-level secret treasure!! This can improve my survivability in the battlefield of the Death Source."

Shu Feng thought about it and threw the blue brocade robe into the Source Energy Evolution Tower.

As soon as the blue brocade robe was thrown into the source energy evolution tower, it was immediately wrapped in countless mucus, forming a large egg.

A demon soul and a demon source sank into the blue brocade robe, and stars appeared in the blue brocade robe.

Countless high-level energy flowed into it and sank into the blue brocade robe.

The blue brocade robe absorbed the power of countless high-level source energy and began to repair quickly, while stars kept lit up.

When the nine stars were completely lit up, the blue brocade robe was immediately completely restored and turned into a complete demon-level secret treasure. He recognized Shu Feng, and became his treasure.

Countless information suddenly surged out of the blue brocade robe and sank into Shu Feng's mind.

This blue brocade robe is a top demon god in the human empire based on nine stars and spent countless time and energy to refine it. The name is [Nine Star Blue Hou Robe]. The defense is extremely powerful.
