The passage was underground, and there was no reference around it, but Li Sichen quickly judged that it was leading to the direction of Tianchi.

"I know, the medicine house is not in the heavenly pool, but under the heavenly pool!" A spiritual light flashed in Li Sichen's mind, and he completely figured out the location of the medicine house. "It turned out to be set up under the Tianchi Pond, this idea is really amazing!"

As if to prove that Li Sichen's guess was correct, in addition to the direction leading to Tianchi, the passage was gradually looking towards the tilt.

More than ten minutes later, Li Sichen walked out of the passage and came to a spacious, bright and bizarre 'underwater world'.

It is said to be an underwater world because above the head, there are rippling blue waves in the heavenly pool.

Li Sichen looked up and found that this place was very different from the Yingzhou Immortal Island on the bottom of the sea.

Above Yingzhou Xiandao, it is shrouded in aura, covering and blocking the sea water and pressure. Above this underwater world, a crystal barrier is shrouded in a semi-permeable membrane.

This crystal barrier not only isolates the lake water in the heavenly pool, but also has the effect of transmitting light, so that the underwater world is full of light, and people walk in it without feeling gloomy. At the same time, because of the special structure of the crystal barrier, people on the lake cannot see through this crystal barrier, and treat it as an ordinary lake bottom, but it is slightly cleaner and more beautiful than other places.

In addition to the crystal barrier above, in this underwater world, there are also ancient buildings, pavilions, carved railings and jade masonry, beautiful, even if it is a well-known Suzhou garden at home and abroad, compared with here, it is also quite a big gap! Not to mention ordinary people, even Li Sichen came here, and his heart gave birth to a little bit of 'even if it is better than the fairyland, it is not inferior'.

Such an underwater world may not be uncommon if it were built in modern times, but it is clear that it existed thousands of years ago. In ancient times, the difficulty factor of such a big project can be imagined! It is not an exaggeration to say that this is a 'miraculous workmanship'.

Just as Li Sichen was curiously looking around, seven people in white robes walked out of the garden and greeted Li Sichen. The leader was the old Zhao who had looked at Li Sichen next to Tianchi before.

"It's him!"

Although he only glanced at it before, Li Sichen had already remembered the image of Zhao Lao in his mind, and when he met again at this moment, he recognized it at once. And this also made Li Sichen more and more sure of his previous judgment: "From Tianchi to Yaolu, there is really another channel!"

Zhao Lao didn't know that because of himself, he exposed some secrets of the medicine house. There were still more than ten steps away, and he opened his mouth with a smile: "Welcome to Pharmacist Yan, I have been in the medicine house for so many years, and I am really happy that there are still new people to join!"

Zhao Lao's performance at this moment was like a kind-eyed old man, without the slightest cold aura from before.

Li Sichen pretended to be excited, walked two steps quickly, and when he arrived in front of Zhao Lao and the others, he said humbly: "How can Yan Mou be able to let all the senior pharmacists greet him? ”

"There's nothing to be afraid of, it's the rule of the medicine house to welcome newcomers. If it weren't for the others, they would all be busy with alchemy at this time and couldn't leave, and they would also come to greet you. Zhao Lao said with a smile, and the rest of the pharmacists also echoed their words, and at the same time looked at Li Sichen with scrutinizing eyes.

Li Sichen also saw that among this group of pharmacists, Zhao Lao's identity and status were the highest. Perhaps, he is one of the only three great pharmacists in the medicine house.

"Come, come, come, let me introduce you, from now on, everyone will be living, cultivating, and working in this medicine house, and they don't know each other, but it's not okay. Zhao Lao showed great enthusiasm, pulled Li Sichen, and introduced the other six pharmacists who came to greet him one by one. In the end, he pointed to himself and said with a smile: "As for me, I'm just a bad old man with no skills." ”

As soon as he said this, the six pharmacists next to him hurriedly slapped their ass.

"Old Zhao, can't you say that, if you don't have the ability, then what are we?"

"That's, that's it, you're one of the only three great pharmacists in our medicine house!"

"Zhao Guizhen's name, even in history, is famous. Your humble words are too outrageous. ”

Zhao Guizhen?

Li Sichen raised his eyebrows slightly, feeling that he had seen this name somewhere.

After thinking about it for a while, he really remembered: "Zhao Guizhen, a Taoist priest of the Tang Dynasty, was recruited into the forbidden middle school by Emperor Wuzong because he was good at alchemy, and he also built a golden talisman dojo for him, regarded him as a first-class figure of the national teacher, and won the trust of Emperor Wuzong." Later, Emperor Wuzong died of poisoning because he took his pills all year round. As a result, there are two theories, one is that he was killed by a rod after Wuzong's death, and the other is that he escaped from the palace and has lived in seclusion among the mountains and wilderness ever since. Now it seems that he should not have died in the palace at that time, but escaped, and after being bumped into by Xu Fu, he developed into a zombie!"

"It stands to reason that Zhao Guizhen's alchemy ability should be very strong, otherwise, he would not have been recruited into the forbidden middle and won the emperor's trust. But why, Emperor Wuzong died because he took the pill he refined? Was it because he lacked the ability to refine the pill? Or did he ......?"

Suddenly, Li Sichen thought of the Five Dragon Pills that Shen Fang had taken before, and the doubts in his mind were instantly swept away.

"I know, it must be the Five Dragon Pill! What Zhao Guizhen gave to Emperor Wuzong was not an ordinary pill, but a poisonous and addictive Five Dragon Pill! Every time he took the Five Dragon Pill, Emperor Wuzong would feel that he was full of energy and extremely comfortable. And Zhao Guizhen also took advantage of this to control Emperor Wuzong in order to seek power and money. But Wulong Dan is a poison after all, and after taking it for a long time, it will not only make people become addicts, but also greatly damage people's physical health, and it is not surprising that Emperor Wuzong finally ended up with a violent death!"

"Pharmacist Yan, what are you thinking?" Zhao Guizhen turned his head and looked at Li Sichen after dealing with the six pharmacists beside him.

"I was shocked by your prestige Old Zhao. Li Sichen pretended to look like he saw an idol, and said excitedly: "I really didn't expect that you are always Zhao Zhenren! The reason why I learned alchemy is because of your old deeds." ”

"That's a bit hypocritical, my experience, the end is not good. ”

Although he said that, the smile on Zhao Guizhen's face undoubtedly showed that he was very useful to Li Sichen's sycophants.

After a few polite words, Zhao Guizhen enthusiastically grabbed Li Sichen's wrist and said with a smile: "Pharmacist Yan, you just came to the medicine house, you must be very unfamiliar, let me lead you around." ”

For this arrangement, of course, Li Sichen will not refuse.

He also wanted to see the situation in the medicine house as soon as possible.

A group of people shuttled through the gardens of this underwater world, Zhao Guizhen introduced as he walked, but most of them were introduced scenery, and none of them were related to the medicine house, even if Li Sichen occasionally found an opportunity to ask, he would forcibly change the topic.

Obviously, before Li Sichen's skills were determined and he was not allowed to take the Five Dragon Pill, Zhao Guizhen would not let him know too much about the situation in the medicine house.

Bypassing a lush rockery, the eight people came to a pavilion with carved railings and jade, and were about to sit down and rest for a while, when they heard a violent explosion next to them, and it was accompanied by a pungent smell of burnt medicine, sweeping in.
