For such a stone, they spent a lot of money, and all their income for several years was invested in it.

You know, apart from the fact that this thing contains a relatively large amount of Yin gas, it will not recover. It is because it was blackmailed by the Palace of Hundred Demons again.

Sure enough, he is worthy of being a demon cultivator, with a small-minded spirit from top to bottom.

****

At the same time, deep down.

Li Su, who felt the Yin Stone rising to a higher level, moved surprisingly quickly.

In fact, the location he is in is already a place that can only be dropped in the foundation building stage, and the location of the Yin Stone promotion is obviously close to the limit that the foundation building can bear, close to the negative Baidu range.

Even Li Su's astonishing physical body had begun to enter a state of load when it exceeded minus 80.

The beating speed of the heart begins to increase rapidly, and through the amazing flow rate of blood, huge heat energy is generated to resist the external cold air.

While running around, Li Su also discovered a rather interesting situation.

Anyone who has played with computers knows that the CPU, power supply, and graphics card of the computer are equipped with fans specifically for cooling to ensure that they do not overheat and crash.

Running in this extremely cold place, Li Su discovered that it seemed that he could do the same.

Although the cold air here was oppressive, it could not hurt his soul. Therefore, through the guidance of his spiritual consciousness, Li Su extracted part of the cold air and used it on his blood-supplying nervous system.

While maintaining ultra-high-efficiency non-stop operation, it cools down overheated blood vessels and keeps them in optimal condition.

Not to mention, this approach not only lengthens the sustainable space for load, but also increases the upper limit a lot.

Well, the physical strength can reach almost 25,000 kilograms. If it explodes nine times, it has already reached 225,000 kilograms.

No, the improvement is not that much.

This should be because his body has grown.

In fact, it broke 20,000, reaching 22,000 pounds!

Is it because of the battle with that foundation builder? Although Li Su was holding the opponent down from the beginning to the end, the huge explosion was very irritating to the flesh and blood.

Especially in terms of tactics, nine times the use is already quite extreme. It can cause a huge squeeze on the body and release the potential.

Originally, he had just awakened and his background had greatly increased.

Sure enough, they are worthy of being a fighting nation. Compared to meditating and practicing, the improvement brought about by fighting seems to be more terrifying for the Jiuli clan.

You know, it took him several months to go from 10,000 jins to 20,000 jins. The growth cannot be said to be full, but compared with the increase in strength of nearly 2,000 jins in one battle, the difference is really not that big.

In the future, we must have more opportunities to fight. Working behind closed doors is not suitable for the Jiuli race.

arrive!

Li Su directly raised his hand and punched a hole in the wall blocking his way. Li Su jumped forward and jumped into the location of Yinshi Shengpin.

I have to say, no wonder this Yin Stone can be upgraded to a higher grade.

It happens to be a small closed cave, and the Yin Stone is located right in the center, which is the only protruding part of the entire cave.

It can be regarded as taking advantage of the right time and location!

Li Su took a deep breath when he looked at the Yin Stone, which had a blue halo and crystal points began to appear on the pure black crystal, which was about the size of a fist.

It is indeed a middle-grade product, and the coldness is really amazing.

It is clearly absorbing the Yin energy from all directions, but the cold energy emitted from the body is still greater than the outside.

The moment he came in, even Li Su's body was almost frozen, and the temperature dropped by at least ten degrees in an instant.

Quickly strengthen the blood energy to generate more heat, support the body, and Li Su's spiritual consciousness is also used at this moment, covering the limbs and bones to ensure that it will not affect the advancement of the Yin Stone.

Soon!

In ten seconds at most, the advancement will be completed.

A middle grade Yin stone, how much does it cost?

Um?

Just when Li Su's eyes were shining, a strange vibration came. At first, it was very low and very light.

But almost in the blink of an eye, the vibrations became louder and louder, and gradually became more obvious. The small cave began to tremble visibly to the naked eye.

earthquake?

No, this frequency is wrong!

Something, something big, is approaching!

His face changed slightly, and there was a fierce look in his eyes. A middle-grade Yin Stone, a treasure of heaven and earth. Since this thing has been discovered by him, it is natural that it is a duck in the mouth. He cannot let it fly.

Without hesitation, spiritual consciousness overflowed directly and flowed down along the source of the earthquake.

Soon, Li Su discovered the target, and as expected, headed straight for it.

However, when he saw clearly the appearance of the thing coming over, Li Su couldn't help but squint his eyes at this moment, and there was a look on his small and delicate face that said, "You are fucking kidding me."

One head was at least ten meters long and weighed at least more than ten tons. It was as long as a pangolin and its entire body was pitch black.

It's a monster, and it's not a small monster, but a big monster, at least for Li Su's level.

Ten tons, that is, almost 20,000 kilograms.

The foundation-building demon, and it's not just an ordinary foundation-building demon, it has to be the kind that has been building a foundation for a long, long time, and started running towards the golden elixir.

Of course, if it were just that, it wouldn't make Li Su look like that.

What really makes Li Su's face turn green is the long, black, strong, and sharp horn on its head.

Damn it, it’s Dragon Horn!!!
