The level of the thirteen elixirs is quite high, which also means that the level of the elixir refined with these elixirs is higher and more difficult, and the pill is definitely very rare.

What's more important is that more than half of these thirteen elixirs are very unpopular for Tang Hao.

In order to combine the pills within two hours, one must have a full understanding of the medicinal properties and ingredients of these thirteen elixirs.

Another point, Emperor Qing did not say how many pills could be combined into these thirteen elixirs, and it was completely up to Tang Haoran to explore it himself.

"Nima, it seems simple, but it's not easy. ”

Although Tang Haoran regarded himself as a master of the Dan Dao, he didn't dare to be careless, he looked through the Book of Heaven again, and after fully understanding several unpopular elixirs, he began to combine.

Soon, the first Danfang combination came out.

"Hum—"

A golden star lit up on the wall of one side of the stone room, indicating that this Danfang was successful.

"Not bad. ”

The Qing Emperor nodded secretly, feeling that this kid had combined a pretty good Dan recipe so quickly, and it seemed that he had a certain Dan Dao quality.

"Combine it into a Danfang again, so fast!"

However, just a dozen seconds later, another star lit up.

The Qingdi was slightly different, and his eyes were more solemn.

If at first, he didn't expect much from this teenager.

And now, as the boy successfully combined two Dan Fang in a short period of time, he couldn't help but put away his contempt.

However, he still felt that the boy had an element of luck in it, and he must have been in contact with similar Danfang before.

"Hey, another star is on!"

In less than half a minute, Tang Haoran successfully combined a Dan Fang.

The Qing Emperor was already a little shocked.

He knew better than anyone else that six of the thirteen elixirs were very unpopular, and the pills that could be combined were all very cold.

"Hum—"

"Hum—"

"The Eighth Star Rises"

……

"The sixteenth star dawned. ”

"The twentieth star dawned. ”

……

In less than an hour, twenty stars were already lit up on the walls.

Emperor Qingdi is such a powerful person, what haven't you seen?

At this time, he was also a little stupid.

In fact, the combination of these thirteen kinds of elixir Dan Fang, is a test question used by a Dan Dao sect in ancient times to assess disciples, if you can successfully combine three Dan Fang in one hour, you can be called a genius, if you combine five kinds, you can be called amazing, more than five, it is a hundred years of rare genius.

Nima, the young man in front of him took less than an hour to successfully combine twenty kinds of Danfang.

How the Green Emperor did not shake.

It's not over yet.

"Buzz—buzz—"

At the end of the hour, five more stars lit up on the snow-colored walls.

In other words, in one hour, Tang Haoran combined twenty-five Dan Fang.

The Qing Emperor was speechless for a long time, and his extraordinary face was a little sluggish.

"Qingdi senior. ”

It wasn't until Tang Haoran shouted that Emperor Qing came back to his senses.

"Oh, have you been exposed to this test before?"

The Qing Emperor couldn't believe that such a young boy had actually combined all the twenty-five pills that could be combined with thirteen elixirs in one hour.

"Why did the Blue Emperor's predecessors ask like this?"

Tang Haoran shook his head and asked.

Emperor Qing could see that the young man was not panicking, not to mention how big the shock in his heart was, he sighed lightly and exclaimed: "Genius, absolute demon-level genius!"

can be so appreciated by the Qingdi, you can imagine how rare it is.

"It's a pity!"

Then, the Qing Emperor was a little disappointed and said: "If you were born 30,000 years early, I will definitely take you as an apprentice." ”

"It is an honor for the younger generations to be appreciated by the predecessors of the Qingdi Emperor. ”

Tang Haoran was extremely modest on his lips, but he was quite disappreciative in his heart, thinking that when he swept the Ten Domains and Eight Desolations in his previous life, killing the Immortal Emperor was like slaughtering chickens and dogs, what kind of demeanor was that.

He wanted to pretend to say to the Qing Emperor, Ben Shao killed a person of your level back then, there are not a thousand but eight hundred, and if you want to accept Ben Shao as an apprentice, you are not qualified enough.

Alas, who made him just a weak chicken now, he must be low-key.

Moreover, before entering the Demon God Tower, he vaguely felt that this was an opportunity, if he could get the Demon God Tower, he might be able to unify the demon race and the human race, so as to solve the crisis facing the earth in one fell swoop.

So now for him, the most important thing is to get the approval of the Demon God Tower, and get the Demon God Tower, as for the inheritance or something, he is really not very enthusiastic, of course, it is of course the best to have high-level cultivation resources.

"Well, although you and I don't have a master-apprentice relationship, but, as I just said, you will be rewarded for passing the assessment. ”

As he spoke, the Blue Emperor waved his hand at the wall that lit up the twenty-five stars.

I saw that the twenty-five stars became more devastating and dazzling, and moved in a specific trajectory, forming a mysterious pattern, and after the wall opened to reveal a dark grid, a small jade statue floating inside.

", Divine Witch Ding!"

Tang Haoran is knowledgeable, and he can see the origin of this tripod at a glance, this medicine tripod is an artifact of the Eight Classics, and it is definitely something that can be met but not sought.

He lacks a high-level medicine tripod now, if he gets this god witch tripod, his Dan Dao level will directly go up to a big level.

"Yes, this is the Divine Witch Ding, for you. ”

The Qingdi wanted to talk about the extraordinary origin of this tripod, but he didn't expect the young man to recognize this tripod at a glance, he waved his hand lightly, and the snow-colored small tripod flew towards Tang Haoran.

"Thank you to the predecessors of the Qingdi for giving me the tripod, the younger generations will never insult this tripod. ”

Tang Haoran took the Divine Witch Ding with both hands, as light as nothing, the simple and barren breath came to his face, and he felt more and more that this Ding was extraordinary, and he said solemnly to the Green Emperor.

"I believe that this tripod is in your hands and will give full play to its value. ”

The Qing Emperor nodded, and said earnestly: "Here in this emperor, your performance can be called perfect, but, Dan Dao is just a side door, if you want to get the inheritance of the Demon God Tower, you must also show enough extraordinary talent in the martial arts." ”

His meaning was obvious, that is, to let Tang Haoran not feel that if he passed this level, he would be able to obtain his inheritance and the Demon God Tower.

"The juniors understand that the juniors must do their best. ”

Tang Haoran arched his hand.

"I don't have much time left for this remnant soul, you go and comprehend the Demon God Codex, I hope I can see you in the Demon God Temple. ”

Qingdi said.

You can still see it in the Demon God Temple!

Tang Haoran's heart moved, it seemed that this was just one of the remnant soul incarnations of the Green Emperor, if he could pass the test and reach the Demon God Temple, he would still be able to see another remnant soul incarnation of the Blue Emperor.

"Qingdi senior, the junior will definitely see you again. ”

Tang Haoran looked at the dissipated figure and said confidently.
