The Strongest Exercise Upgrade System

"This person is also so idle. He doesn't practice the human exercises well. Why does he have to practice the monsters' exercises?

This is great, nothing can be done, and in the end, my life is ruined here, which is really not worth promoting! "

Zeng Yu shook his head and continued searching with a torch. A black bag next to the skeleton suddenly attracted Zeng Yu's attention.

Zeng Yu picked up the black bag and took a closer look.

The bag is not big, only the palm of the hand is big, the mouth of the bag is bound by a rope, and the mouth of the bag is obviously sewn up by someone and cannot be opened.

The entire black bag was covered with some weird, crooked runes, which looked rather strange.

"Is this the storage bag in the biography?"

Thinking of the name storage bag, Zeng Yu's original Gu Jing Wubo heart suddenly became excited.

Storage bag, that is a treasure that can only be used by immortal cultivators!

According to one bag, many things can be put into it, and the space inside is much larger than the storage charms in Zeng Yu's hands.

However, to use the storage bag, you must have a mana cultivator.

Zeng Yu is only in the last tenth stage now, so naturally he can't open this storage bag.

Zeng Yu treasured this storage bag away.

A pig and a monkey also stood quietly beside Zeng Yu, watching Zeng Yu put the storage bag in his arms.

After finishing this, Zeng Yu raised the torch again and carefully watched the mural on the wall of the cave.

These murals are obviously not painted by today's people, but are like those left by the monster clan from a long time ago.

The more Zeng Yu watched, the more mysterious these murals felt, and a breath of wildness came to his face following Zeng Yu's research.

Zeng Yu's heart moved: Maybe the system can see if it can upgrade the exercises here and turn them into exercises that can be practiced by all human races!

Thinking of this, Zeng Yu immediately asked the system in his mind: "System, can you upgrade the exercises on the murals and turn them into exercises that even me can practice?"

System: Ding, the system is scanning...

Ding, the system has scanned the monster clan's exercises, one of the Baihu bone-forging skills, which can be upgraded from an earth-level low-grade to an earth-level medium-grade, and the upgraded humans can also practice!

Ask the host to confirm whether to upgrade?

Zeng Yu's eyes lit up and he immediately said without hesitation: "Upgrade!"

System: The technique is being upgraded, please wait...

Zeng Yu waited for a while, then heard the voice of the system resounding in his mind: The upgrade is completed, please check the host...

As soon as the voice fell, countless information flooded into Zeng Yu's mind.

"Baihu bone forging art! Middle-ranking prefecture level! I finally got a predecessor level exercise that I can practice!"

After Zeng Yu checked the information in his mind for a while, he became excited and said very loudly.

The Human Emperor Scripture is a method of the advanced realm, and one cannot practice without the advanced realm.

Therefore, although Zeng Yu got the Human Emperor's Scripture, he could only read it, not practice it.

But this white tiger bone forging technique is different. It belongs to the body forging technique of the monster race and is suitable for martial arts of all realms.

Of course, the lower the level, the better the effect of cultivation.

Moreover, the grade of this body-building exercise is not low, and its grade reaches the Lin level, which is the superior exercise used by the Baihu clan to cultivate monster bodies in ancient times.

Now that Zeng Yu used the cultivation technique upgrade system to upgrade this way, not only did he upgrade the first rank, it also turned this technique into a cultivation technique that both the human race and the monster race can practice.

Zeng Yu's heart was overjoyed.

Zeng Yu looked at the skeleton again, sighed, and said, "Senior, if you had the cultivation technique upgrade system like in my mind back then, I'm afraid you wouldn't waste a lifetime here!"

Zeng Yu looked around, and saw that except for a skeleton in the cave, the rest of the cave was clean and fresh, which was very suitable for human living.

Zeng Yu plans to live here for a period of time, while practising Baihu bone forging skills, it is also convenient to find Seven Color Beads.

Therefore, Zeng Yu had to spend some time and effort to get the bones from the cave out of the cave, find a place in the valley, and bury the bones.

So that the bones can be put into the soil for safety.

After doing this, it was not too early to see sex, Zeng Yu and the two guys found firewood and started a fire in the cave.

Afterwards, Zeng Yu took out some dry food from the storage talisman and distributed it to pigs and monkeys.

Pigs are not picky eaters. No matter what Zeng Yu gives, it will eat whatever.

On the contrary, the monkey didn't seem to have a cold with meat, and ignored the jerky that Zeng Yu handed it. Instead, he liked the peaches Zeng Yu gave him.

These peaches were all wild fruits Zeng Yu found in the mountains and forests. Zeng Yu saw that these wild fruits were sweet and juicy, so he picked a lot of them and put them in the storage talisman. Unexpectedly, they met the taste of monkeys.

After eating, the pig monkey became more familiar and dependent on Zeng Yu.

Zeng Yu lay on the stone bed in the cave, and two guys laughed on the bed. The monkey scratched Zeng Yu's head and body from time to time, and the pig's short legs stepped on Zeng Yu's belly from time to time.

The two naughty guys made Zeng Yu, who was about to fall into deep thought, to stop thinking.

Sitting up from the bed, looking at two things and saying: "Don't you need to rest?"

The two things shook their heads at the same time.

The clever appearance made Zeng Yu feel very weird.

If it wasn't for these two things that one is a pig body and the other is a monkey body, Zeng Yu would think that these two things are actually human.

Although they are not humans, their intelligence is no lower than humans.

According to Zeng Yu's estimation, the IQs of these two things are about to catch up with those five or six year olds!

It was just that Zeng Yu had trouble communicating with them because the two things couldn't talk.

Zeng Yu looked at the cunning in the eyes of the two things, and couldn't help raising his hands to surrender, saying, "Well, I admit that you two have good energy.

But I am different from you, we humans all have the habit of rest.

So I want you to know that when I rest, you all have to be behaved and don't bother me, you know? "

Hearing the words, the two things nodded again, and then began to fight with Ruo Wurong.

"What is your name?"

Zeng Yu looked at them again and asked.

"Squeak!"

"Humph!"

The answers of the two guys left Zeng Yu with black lines.

"Forget it! Let me give you a name, so that I can call you later! You will be called Sun in the future, and you will be called Zhu Bujie!"

Zeng Yu directly applied the surnames of Senior Brother and Second Senior Brother, and helped the two guys choose a name each.
