Zhao Feng fought from the first layer to the twentieth layer, and the rewards he received were constantly stacked, that is, he had already obtained two hundred and ten dragon sources.

And right now, he only needs more than ten copies of Dragon Source to advance to the next stage, two hundred and ten copies, which is enough.

However, he is still in the process of breaking through, so he has not received the Dragon Source.

"Twenty-one, go on!"

Zhao Feng's eyes narrowed slightly, and he climbed the twenty-first layer of the stairs.

From this level, he has to have his hole cards out of layers.

"Killing Mark, Ten Bursts!"

Stepping on the twenty-first floor, Zhao Feng, who saw the gatekeeper on the twenty-first floor, directly broke out ten killing seals, increasing his power by twenty times.

Originally, he only had five chances to kill the seal, but this black dragon tower was very strange, killing these black dragons guarding the pass would also get killing points, so his killing mark was raised to ten when it was on the twentieth layer.

Zhao Feng, who had increased his strength by twenty times, still killed the twenty-first level of the guarding black dragon in seconds, and then stepped on the twenty-second floor.

The twenty-second layer is still a twenty-fold explosion!

The twenty-third layer, still twenty times!

Twenty-four floors, twenty times!

However, at the twenty-fifth layer, it would be difficult to kill this guarding black dragon with a twenty-fold burst.

After all, Zhao Feng after the merger was a seventh-rank true monarch, and the twenty-fifth-layer guarded black dragon was twenty-five realms higher than him, reaching the fifth-grade true emperor.

Moreover, this has just reached the limit of the suppression of the Ten Thousand Beasts Map, although this battle can be fought, it is estimated that it will not be too easy.

After a big battle, Zhao Feng still killed the black dragon guarding the twenty-fifth floor and cleared the twenty-fifth floor.

At this time, his Dragon Source rewards had been stacked to more than three hundred.

And outside the Black Dragon Tower, that group of foreign geniuses were already speechless in shock.

"Too, it's really terrifying, I actually passed the twenty-fifth floor, it's really a super demon!"

"Five-grade genius, worthy of being a five-grade genius, you know, our Waifu Black Dragon Tower is only thirty floors at the top, and no one has ever hit it, as soon as he came in, he hit the twenty-fifth floor, it's really terrifying!"

"I remember, our Black Dragon Academy only reached the Jupiter River on the first day, and the highest record was only twenty-seven layers, right?"

"That's right, Senior Brother Duanmu Xinghe is also a fifth-grade genius, and he is already a million-scale genius, it's really amazing!"

The number of these geniuses in the outer province is only a hundred at most, because if there are more than a hundred, they can apply to be promoted to the inner mansion.

However, Zhao Feng's World-Destroying Ghost Dragon fused more than two hundred top-grade dragon scales, far surpassing them.

At this moment, Zhao Feng had already given up the challenge of the Black Dragon Tower and walked down.

Everyone looked at his indifferent face, and they didn't dare to approach, after all, such a genius has a very strange temper, in case it angers him, don't think about it in the future.

Zhao Feng also did it on purpose, so as not to catch up with these flies, after he left the Black Dragon Tower, he went directly to receive his reward, a total of three hundred and twenty-five dragon sources.

Moreover, the record of the Black Dragon Tower will refresh the number of dragon sources that can be received each year at this level.

Originally, Zhao Feng could only receive one Dragon Source every year, but now it has soared directly to three hundred and twenty-five.

It's just that Zhao Feng can't wait for less than a year.

Besides, if he is given a year, he can break through dozens of times, which is enough to reach the True Venerable.

After receiving three hundred and twenty-five dragon sources, Zhao Feng quickly returned to his residence and let the world-destroying ghost dragon fuse these dragon sources.

A dragon source, with ten superb dragon scales, a superb dragon bone, and a bottle of superb dragon blood.

After the World-Destroying Ghost Dragon fused these dragon sources, the increase was directly increased to fifteen times.

It's just that after increasing to fifteen times, the degree of increase is not visible, but the increase is still the same.

"The fusion speed of the World-Destroying Ghost Dragon, combined with the cultivation space, is simply boundless, and the current World-Destroying Ghost Dragon has finally reached the point of being the best genius of the Ten Thousand Scales......"

Zhao Feng's eyes narrowed slightly.

In the Black Dragon Academy, the best ten thousand scales are the standard of a half-step True Emperor, and the World-Destroying Ghost Dragon has actually been completed in the True Monarch realm.

It's just that in order to fuse so many dragon sources, it took a lot of time for the World Destroying Ghost Dragon.

In fact, ten days have passed.

In the past ten days, Zhao Feng's realm has soared to the fifth-grade true monarch, while the world-destroying ghost dragon is the nine-rank true monarch.

However, just as Zhao Feng was about to continue to challenge the Black Dragon Tower of the Outer Mansion, Pan Hong suddenly came to transmit the sound.

"Zhao Feng, is it convenient now?" Pan Hong said.

"What's the matter?"

Zhao Feng raised his eyebrows.

Seeing Zhao Feng's reply, Pan Hong immediately rushed to Zhao Feng's mansion.

"There's something I have to talk to you about. ”

Pan Hong walked in and said, "I heard that you beat the Black Dragon Tower to the twenty-fifth floor a while ago?"

"Not bad!"

Zhao Feng nodded and said, this is already the news ten days ago, Pan Hong has been in retreat for the past few days, and it is normal to know just now.

"Master has fallen, and now the Black Dragon Sect knows about it, and someone has already come to inquire about me before, so the position of the Ninth Black Dragon Envoy is vacant. ”

Pan Hong paused, and then continued: "Master instructed me to continue to inherit the Ninth Black Dragon Holy Envoy before, but with my current condition, I am afraid it will be difficult to shoulder the heavy responsibility......

Hearing this, Zhao Feng somewhat understood what Pan Hong was trying to say.

"I'm only a second-grade genius, but you're a fifth-grade genius, and I disclose to the public that you are also a deputy apprentice, with your qualifications, there is a great chance that you can become the ninth holy envoy. Pan Hong said.

Sure enough, Pan Hong wanted him to become the ninth holy envoy of the Black Dragon Sect.

However, at this very moment.

"Ding! Congratulations on triggering a random quest and becoming the Ninth Holy Envoy of the Black Dragon Sect!"

A system prompt suddenly sounded in Zhao Feng's mind.

Although Zhao Feng didn't want to be the ninth holy envoy, now that the mission came out, it was difficult for him to refuse.

"However, I'm just a true monarch now, it's too much!" Zhao Feng said.

"The Black Dragon Holy Envoy has always looked at qualifications, not realms. As long as you can pass through the Black Dragon Stream and get the Black Dragon Inheritance, then you are the Ninth Holy Envoy. Pan Hongdao.

Black Dragon Stream!

After Zhao Feng heard this name, he couldn't help asking, "Black Dragon Stream, what is it?"

"The Black Dragon Stream is the place where the Black Dragon of the World Destroys the World falls, where there is the Dragon Soul of the Black Dragon of the World, as long as you can get the Dragon Soul, then you can become the Black Dragon Holy Envoy!"

Pan Hong explained: "Master also got the dragon soul before, but after he died, this dragon soul dissipated. ”

"Is there still a dragon soul?"

Zhao Feng's eyebrows furrowed.

Dragon scales, dragon bones, and dragon blood are fused, and the effect will be better than a single one, and if there is another dragon soul, the effect will definitely be very good.

Hearing this, Zhao Feng was moved.
