Glancing back at the three outer disciples who were holding the registration list in their hands, Du Kun began to buy demon beasts.

Since he dared to come here to buy demon beasts openly, he was naturally prepared, according to his observations, the scattered cultivation in the foundation building period would be picked up by the elders of the sect in advance, and then there would be three outer disciples like Yuan Fei who were responsible for registering those who practiced qi and scattered cultivation into the sect.

As long as there were no high-ranking monks, he was relieved.

In fact, as early as yesterday before leaving, he had already discussed with the two gatekeeper disciples, and asked them to help inform the group of outer disciples who wanted to sell demon beasts, saying that he would buy them in the square today, so that there would be more demon beasts that were captured alive.

After all, this price is twice as much as the corpse of the demon beast!

No one is not tempted.

Therefore, today in the square, there are many monsters trapped like zongzi, lying there, dying.

When I swept it away, there were no less than a hundred.

Du Kun's eyes flickered, and he slapped the storage bag, and in an instant, dozens of rock spirit crystals glowing with cold black glows flew out one after another, hovering alternately in the sky, with extraordinary momentum......

"Ding! Congratulations to the host [Du Kun] for killing the Black Wind Leopard and gaining 1500 XP! ”

"Ding! Congratulations to the host [Du Kun] for killing the Golden-billed Crow and gaining 1500 XP! ”

"Ding! Congratulations to the host [Du Kun] for killing the Bone Eater and gaining 1100 XP! ”

"Ding! Congratulations to the host [Du Kun] for killing the Rock Serpent and gaining 2500 XP! ”

……

The constant sound of the system echoed in his head.

It was also mixed with Luo Wuji's exclamation: "Damn, why didn't I think of this method before, this is so cool, it's just a system bug!" ”

"Ding! Congratulations to the host [Du Kun] for upgrading, the current realm [Qi Training Period Ninth Layer]"

Suddenly, there was a surge of aura in his body, and his cultivation directly entered the ninth layer of the qi training period, Du Kun was so excited that it was difficult to attach, looking at most of the remaining demon beasts on the ground, the harvesting speed immediately accelerated a lot.

A few minutes later.

"Ding! Congratulations to the host [Du Kun] for upgrading, the current realm [Qi Cultivation Period Tenth Layer]"

There are ten layers in the Qi training period, and the ten layers are the realm of the Great Perfection, and it is also the highest level realm in the Qi training period.

Upward, it is to build the foundation.

Every time he kills a demon beast, Du Kun can earn a lot of spirit stones in addition to his experience.

For example, a living Black Wind Leopard, his purchase price was 5 lower grade spirit stones, but after he killed it, the corpse was recycled to the system, that is, 10 lower grade spirit stones, which was doubled.

And those outer disciples are also happy one by one, and on weekdays, they can only recover the corpse of a demon beast with a converted price of less than 1 lower grade spirit stone, and when they are brought to this mysterious elder, the price has directly increased several times.

Especially the people who had already tasted some sweetness yesterday, they almost stayed awake last night, wandering around the periphery of the Ten Thousand Mountains and Forests, killing and capturing all kinds of demon beasts that could be taken alive.

The big man with the axe on his back was one of them, and he brought 3 rock snake corpses alone, 6 black wind leopards, 3 of which were alive, 2 bone eaters, and 1 golden-billed crow, which can be said to have received a lot of goods.

After trading with Du Kun, he smiled from ear to ear, and he had great plans to continue to cooperate in the future.

In the end, those scattered cultivators who had not yet registered in the sect began to be unable to sit still, and some people went directly into the mountains and forests to fight demon beasts.

Even the three outer disciples who were in charge of registration swallowed their saliva fiercely, and soon joined the ranks of fighting demon beasts......

"Ding! If the host's experience value is detected, it can advance to the foundation building period at any time, whether it is directly advanced to build the foundation, and it can be advanced at the moment - ordinary foundation building (no catastrophe is coming)! ”

"Ding! Continue to accumulate experience, you can advance - innate foundation building (there is a catastrophe coming)! ”

I'll go, what's the situation, there are two kinds of foundation building!

Du Kun was directly stunned.

"I didn't have that the last time I advanced to the foundation building period, that wasn't the case." Luo Wuji was also a little puzzled.

"Aren't you the former system boarder? How could it not be known? And what the hell is the catastrophe coming to you, damn, I think I'm still going to build a foundation directly, a little safer. Du Kun said with some horror.

If you accumulate more experience, you can advance to the innate foundation, but there is a catastrophe coming later.

He had seen a lot of the word Heavenly Tribulation in novels before, it was life-threatening, and he didn't want to try that kind of taste of five thunderbolts.

Think about it......

Ordinary foundation ......

Actually, it's enough!

"Don't rush to advance first, maybe this is a system update and upgrade, so there will be an anti-heaven option of congenital foundation." Luo Wuji hurriedly stopped.

"Damn, system upgrades? Still against the sky? I think it's looking for death, right? Du Kun continued to harvest the demon beasts, and at the same time quietly complained in his heart.

"I'll tell you the truth, in fact, after I ascended to the immortal realm, this system had a state of paralysis, at that time, whether I killed immortal cultivators or demon beasts in the immortal realm, there would not be the slightest increase in experience points, even the immortal beasts killed several heads, and the result was still, not even the immortal value exploded." Luo Wuji's voice carried a hint of unwillingness.

"Isn't it? God system paralyzed, play me, right? Du Kun stood stunned on the spot, and even the speed of harvesting demon beasts was paused.

Everyone was stunned, thinking that he didn't want it, and their expressions showed a nervous expression, but they didn't speak, and waited quietly.

Luo Wuji didn't answer his question, and said to himself: "Later, when I was trapped and killed by the group of old miscellaneous hairs in Buzhou Immortal Mountain, my body was burned by the Nine Flavors of Heavenly Flames, and at the last moment, I blew up my body and killed one person desperately, but at that time, the system reward appeared again, the system returned to normal, and my soul was also introduced into the system by an incredible force at that time, and it became what it is now." ”

"I couldn't understand why this system was paralyzed for no reason for more than 2,000 years, and then after staying in it for a while, I finally discovered a big secret, this system is likely to continue to improve, and now you and I see these functions, maybe just the tip of its iceberg."

"You're saying that the last time the system went down was because it was upgrading?" Du Kun seemed to understand.

"That's pretty much what it means, so when it stays on you this time, the system will give the innate foundation building, the strongest foundation building realm that only appeared in the Hongmeng period, if I expect it to be correct, when you marry Dan, it is very likely that a similar situation will occur! As for the Heavenly Tribulation, you can make more preparations, the Heavenly Tribulation corresponding to the realm will not be so powerful. ”

In fact, Du Kun didn't listen to Luo Wuji's previous words at all, but the last sentence lifted his spirits.

"Wouldn't the Tribulation be very powerful?" A gleam flashed in his eyes, and he gradually revealed confidence: "Then give it a try, the strongest foundation building, it sounds very awesome." ”
