After reading the information about the wind spirit rat skin, Ye Su's expression couldn't help but be shocked.

Even if he knew that the rat skin of the wind spirit mouse brought out from the immortal realm, it would have a great effect in the mortal world.

But I didn't expect that there would be so many abilities.

It is not only fireproof, waterproof, electricity-proof and anti-corrosion...... It is anti-mildew and anti-virus, and can also prevent the attack of mortal weapons.

That's really a bit of a powerhouse!

You must know that the Wind Spirit Mouse is just the most ordinary low-level wild monster in the Immortal Realm, and it can be seen everywhere, and there are huge numbers!

As long as you take out the money, the rat skin of the wind spirit mouse is simply as much as you want!

If you get them to the mortal world, wouldn't you get rich......

It took a while for Ye Su to come back to his senses.

The rat skin of the wind spirit mouse is obviously not enough to make a piece of clothing, and Ye Su must get some more wind spirit mouse skin next.

However, just as Ye Su was about to put down the skin of the wind spirit mouse in his hand, the voice of the system suddenly sounded.

"Ye Su, you don't have to put the Wind Spirit Mouse Skin outside, you can try the Mortal Backpack that was just opened for you. You just have to think about it, open it, and you can put the Wind Spirit Mouse Skin in it. ”

"Oh!"

Ye Su nodded.

Then, according to what the system said, Ye Su gave it a try.

The next moment, on the side of Ye Su's hand, the void quietly shattered, and a palm-sized hole suddenly appeared, and it was extremely dark inside.

The system went on to say.

"Alright, you've opened the Mortal Realm Backpack, now all you need to do is reach out and put the Wind Spirit Rat Skin inside! When you're skilled, accessing items is just a matter of seconds. ”

Listening to the sound of the system, Ye Su tentatively reached out and put the wind spirit mouse skin in his hand gently.

Ye Su's hand didn't feel anything when he reached into the hole, that is, in the Mortal Realm Backpack.

However, when Ye Su's hand was withdrawn, the wind spirit rat skin in his hand had disappeared, and the black hole that was originally on the side of his hand was also instantly annihilated and ceased to exist.

Immediately after, Ye Su tried to take out the Wind Spirit Mouse Skin from the Mortal Realm Backpack and put it in again.

It's like juggling.

After doing this a few times, Ye Su's expression was already uncontrollable excited.

This system, in this short period of time, has brought me a lot of surprises.

Fortunately, Ye Su's attention didn't stay on this matter for too long, and soon he focused on the other items on the table.

At the same time, when Ye Su picked them up and looked at them carefully, he also read their information one by one.

"[Red Potion]: After taking it, you can directly restore the dying mortal to his state, and increase his attack speed by 100%, 100% running speed, and 50% attack speed!"

"[Bai Fan-level staff]: The lowest fire-type staff in the Immortal Realm, after use, it can shoot out one hot and high-damage fireball after another, and generally speaking, it can kill mortal Jindan-level monks in seconds!"

"[Bai Fan-level Dagger]: The lowest ordinary weapon in the Immortal Realm, it is indestructible in the mortal realm, and after holding it, it can kill the mortal Jindan-level monk in one blow!"

"[Seven-color Hundred Leaf Flower]: A kind of medium- and low-level plant of Immortal Lin, which is common everywhere, can exude the light of seven colors of red, yellow, orange, green, blue, and purple, and can also exude a small amount of immortal energy. Mortals who leave it in the room for a long time have the effect of prolonging life! ”

……

"[Spirit Coins]: An ordinary currency in the Immortal Realm and the Upper Realm, which can be used to buy items, and it also contains a small amount of Upper Realm Immortal Qi, after being absorbed by mortals, they can directly complete the foundation building!"

Finally, when Ye Su picked up a glittering spirit coin on the ground, he read its information and immediately couldn't wait to ask the system.

"How can I absorb the immortal energy in this spirit coin?"

System: "It's simple, just put it in the palm of your hand and think about absorbing it!" ”

As soon as the voice on the system's side fell, Ye Su immediately followed it.

After a second or two.

A white aura suddenly rose from the spirit coin, fell into Ye Su's palm, and quickly disappeared.

At this time, Ye Su also suddenly felt an incomparably warm breath, wandering in his body.

The next moment, Ye Su inexplicably felt a heat in his body.

"Crackling!!"

The bones in the whole body trembled.

Next......

Then there was no other reaction.

At this time, the news of the system also sounded suddenly.

"Congratulations, you have been successfully promoted to the Foundation Building Monk!"

I thought that something would happen, but I didn't expect that the system would simply notify me that the foundation had been built.

Rao is Ye Su couldn't help but be stunned.

Cultivating immortals, is it that simple?

So why are those online novels so difficult to write?

It's really a bit beyond Ye Su's expectations.

"Bang Bang!!"

"Ahhh

……

And at this time, a strange voice sounded in Ye Su's ears inexplicably.

It seems to be coming from downstairs.

"Wow! It hurts!! ”

"Tap!"

……

This voice is a bit indescribable, although he has eaten pork, Ye Su, who has seen pigs running, is completely shocked at this time!

That voice is very familiar to Ye Su.

It's the beautiful teacher downstairs who looks extremely cold and unapproachable, with countless suitors, and basically every time they meet, you can see her being given flowers.

I didn't expect to be so unrestrained when I did that kind of thing!

Ye Su felt that his three views had been subverted a little.

At this time, the system seemed to know what Ye Su was thinking, and said slowly.

"Ye Su, because you became a foundation building period monk, your sense of hearing, sight, smell, etc., has been greatly improved, so you can hear such a voice. But if you want to see that kind of picture, you'll have to wait until you become a Jindan monk! ”

"At that time, your vision will be able to penetrate some simple objects......"

Listening to the system's explanation, Ye Su had the urge to become a Jindan monk immediately.

"Bang bang...... Syllable! ”

"Why are you so fast! It's only a minute! ”

The rain downstairs stopped, and Ye Su's ears rang with the complaint of a cold and beautiful teacher......

Ye Su also came back to his senses, it was too intense just now, and he couldn't help but take a deep breath slightly.

"Dididi!!"

At this time, Ye Su's mobile phone on the table suddenly rang.

Ye Su picked it up and looked at it.

It's my own "faithful" reader, and I sent it in early summer.

There is no doubt that the third watch in the middle of the night sent a message to himself, just to urge the change.

As a dedicated web author, Ye Su sighed slightly, and then looked at the information.

Early Summer: "Brother Salted Fish, how many changes are you going to do today?" Yesterday was only three watches, and it was not pleasant to watch, do you want to add more! I can tip you! ”
