Along the passage, Chu Feng walked forward.
Not long after, four forked roads appeared in front of him.
Chu Feng hesitated for a moment, then asked: "Senior Heiteng, where should I go next?"
Heiteng said angrily: "You ask me, who should I ask?"
Chu Feng smiled and said, "Then I'll just find a passage. Anyway, Senior Black Teng, you will protect me."
After saying this, he walked directly towards the leftmost passage.
Seeing Chu Feng being so decisive, Heiteng had no choice but to say: "You kid, you can't be so confident just because I'm protecting you..."
In comparison, the passage within the forked road is narrower and can only accommodate one person.
However, this passage is not too long.
It only took Chu Feng five minutes to reach the end.
At the end of the passage is a secret room.
In the center of the secret room stands a stone platform.
A treasure chest of bones exuding the aura of death was placed on the stone platform, seemingly waiting for someone to open it.
After hesitating for a moment, Chu Feng finally walked up and began to carefully examine the skeleton treasure box in front of him.
This skeleton treasure chest is in a closed state at this moment, and it obviously requires a key to open it.
Chu Feng immediately took out the four key-shaped crystals from the Sumeru Ring and began to compare them one by one.
It didn't take long for Chu Feng to confirm that the key crystal taken out from the skull of the skeletal dragon exactly corresponded to the skeletal treasure chest in front of him.
Then, Chu Feng took a deep breath and directly inserted the key into the keyhole.
"Don't you think about it any more?"
"If nothing else happens, when you open this skeleton treasure chest, the power in this abyss magic crystal will be input into Manus' body. This is his purpose."
At this moment, Heiteng's voice sounded in Chu Feng's ears again.
"Of course I know, but the question is... senior, aren't you here?"
Chu Feng smiled and said calmly: "What's more, I have to know what's in this treasure box before I can continue to trade with the devil, right?"
Immediately afterwards, Chu Feng turned the key without any hesitation.
Accompanied by a crisp "click" sound.
The skeleton treasure chest in front of him was finally successfully opened by Chu Feng.
An extremely strong death aura immediately spread towards the surroundings.
However, even Chu Feng did not expect that what was stored in the skeleton treasure box in front of him was actually a skeleton sword!
The reason why it is called the Skeleton Saber is because the entire body of the sword is bone white, and there is a skull inlaid on the hilt, which looks extremely weird.
Just when Chu Feng was about to reach out and pick up the skeleton sword, Heiteng's voice sounded again.
"This is the 'Skeleton Demon Blade'. It is one of the weapons of Manus. This abyss demon used it to kill many strong human beings and absorbed a lot of death energy."
"I really didn't expect that this magic knife would appear here."
"If I remember correctly, in addition to this 'Skeleton Demonic Blade', Manus should also have a 'Skeleton Demonic Armor'."
"Tsk tsk... It seems that Manus really spent a lot of money in order to escape the seal."
Just as Heiteng was speaking, Chu Feng also stretched out his hand and grasped the bone demon blade.
However, in the next second, an extremely strong death energy spread from this bone demon blade!
Suddenly, Chu Feng felt that his right arm became extremely cold, and the gray color began to spread from his fingers to his arm!
This sudden change caused Chu Feng to immediately let go of the Skeleton Demon Blade in his hand.
Because his right arm has begun to be eroded by the death energy!
Immediately afterwards, Chu Feng did not hesitate at all, and immediately activated the Divine Elephant Prison Suppression Technique, trying to suppress this death energy with his own energy and blood!
Obviously, this method is quite effective.
Under the suppression of the power of Qi and blood, the death energy was gradually forced out of Chu Feng's body.
The gray color also faded from his arm, returning to its normal blood color.
At this moment, the way Chu Feng looked at the Skeleton Demon Blade had completely changed.
Heiteng on the side sneered: "Okay, be careful in the future. I told you just now, this is the weapon of Manus, and it is not something you can easily control."
"Fortunately, you just held it for a moment and then let it go. If you had kept holding it in your hand, I'm afraid your life force would have been sucked away by this knife."
"This is really a magic knife."
After hearing Heiteng's words, Chu Feng couldn't help but have a flash of fear in his eyes.
However, at this moment, the Chi You Sword on his back suddenly began to tremble violently!
Chu Feng was stunned for a moment, and then he immediately took off the Chi You knife from behind.
He could feel that Chi You Dao seemed to be very... longing for the death energy exuded by this bone demon blade.
After hesitating for a moment, Chu Feng immediately put the Chi You Sword and the Skeleton Demon Blade together.
The next second, Chi You's shadow immediately condensed and took shape from Chi You's sword.
Then, the phantom of Chi You in front of him began to swallow the gray death energy in front of him.
Ball after ball of gray and dead air were swallowed into the mouth by Chi You Xuying.
And every time a ball of gray-white death energy is swallowed up, Chi You Xuying's size will also increase by one point.
"It seems that the weapon spirit of your weapon can grow by swallowing this death energy."
Heiteng glanced at Chi You Dao and said calmly: "If nothing happens, your weapon spirit will be able to grow to the fifth level in a short time."
"Fifth level weapon spirit?"
A look of surprise flashed across Chu Feng's eyes.
He obviously didn't expect that Chi You Sword would be able to get such a significant improvement just by letting it absorb some of the death energy emitted by the Skeleton Demon Blade.
It seems that this bone demon blade is really not simple.
Heiteng suddenly said: "Boy, you have two choices now."
"What?"
Chu Feng was stunned for a moment, obviously he hadn't reacted yet.
"The first option is to wait until you become strong enough and then try to control this bone demon blade."
"After all, this is Manus's weapon. It is far more powerful than the knife in your hand."
"Furthermore, this Demon Skeleton Blade also contains a weapon spirit, but with your current strength, you are still unable to activate it."
"The second option is to continue to use the knife in your hand."
"If you choose this way, just continue to let it absorb the death energy of the Skeleton Demon Blade."
After hearing this, Chu Feng finally realized something and asked: "Is the death energy absorbed by Chi You's sword... important?"
"Of course, it seems you are not too stupid."
Black Teng said calmly: "What the knife in your hand has absorbed is not any ordinary death energy, but the original death energy of this bone demon blade."
"If all the original death energy is absorbed, the level of the Skeleton Demon Blade will at least drop by several levels, and it is not impossible to even scrap it directly."
"so serious?"
A look of astonishment flashed across Chu Feng's eyes.
"Of course. Otherwise, why do you think the weapon spirit of your sword can grow so fast?"
Heiteng said angrily: "Okay, let's make a choice quickly."
"According to the speed at which this thing absorbs death energy, it won't be long before the level of the Skeleton Demon Blade is going to drop."
However, Chu Feng smiled casually, put his hand directly on the Chi You Sword, and said calmly: "I choose the Chi You Sword."
"Why?"
This time, it was Kurotou's turn to be surprised.
"Although the Skeleton Demon Blade is very strong, after all, it is easier to use your own weapon."
Chu Feng held the Chi You Sword, chuckled and said, "What's more, one day, this Chi You Sword... will become as powerful as this Skeleton Demon Blade."
"Even more powerful!"
"You guy... you are really brave enough to think."
What Chu Feng didn't expect was that this time, Heiteng did not laugh at him, but said calmly: "But now that you have made a decision, don't regret it."
"I never regret it."
Chu Feng smiled and clenched the Chi You knife in his hand.
At this moment, Chi You's shadow has absorbed a lot of death energy and returned to Chi You's sword.
Looking at the scene in front of him, Heiteng calmly explained: "This Chi You Sword has absorbed too much death energy and has now entered a deep sleep state."
"At the very least, it should be impossible to wake it up in a short period of time."
"If nothing else happens, after the weapon spirit wakes up, it should be successfully promoted to the fifth-level weapon spirit."
Chu Feng nodded and said, "Then after the weapon spirit is successfully promoted, can it continue to absorb death energy to increase its level?"
"You kid..."
Heiteng said helplessly: "Looking at your posture, you really won't stop until you eat up this bone demon blade."
"With this weapon in your hands, you will be damned for eight lifetimes."
Chu Feng didn't feel embarrassed at all. Instead, he chuckled and said, "Just make the best use of everything."
"Of course you can continue to absorb it."
Heiteng said: "Although Chi You Sword absorbs the original death energy of the Skeleton Demon Blade, the amount of original death energy is not as small as you think."
"If all the original death energy is absorbed, it should be enough to upgrade the Chi You Sword's weapon spirit to the sixth level."
Upon hearing this, Chu Feng's eyes immediately showed a hint of joy.
The power of the sixth-level weapon spirit must be much stronger than that of the fourth-level weapon spirit.
Just a treasure chest of bones allowed Chu Feng to gain so much, which was obviously far beyond his expectations.
And in his hand, there are three keys.
This means that he can at least open three treasure chests of the same level!
As for whether the Lord of the Abyss 'Manus' will break through the seal after opening all the treasure chests, this is not something he should consider.
Anyway, Senior Black Teng said that he would settle it for him.
With Chu Feng as his backer, he naturally has nothing to fear.
At this moment, Heiteng on the side has been watching the Chi You Sword in Chu Feng's hand.
In fact, there was one thing that he had not told Chu Feng since just now.
That is...
In his knowledge, it is rare for lower-level weapons to absorb upper-level weapons.
Logically speaking, if the Chi You Sword and the Skeleton Demon Blade are put together, the most likely scenario is that the Chi You Sword is eroded by the death energy.
However, the current situation is completely reversed.
Not only was Chi You's sword not eroded by the death energy, but it in turn absorbed the original death energy of the Skeleton Demon Blade.
It seems... this boy's weapon is also unusual.
