Bai Shen here, come back from Tianji Pavilion, sort out your emotions, and return to Baifu.

In the West Hall, Bai Shen did not mention these things to Lu Lisi, and Lu Lisi did not ask.

Bai Shen had breakfast with Hou Sui, and then took Hou Sui to the study and continued to teach him kendo.

Hou Sui listened very seriously, and kept in mind the secrets of the kendo and various secrets that Bai Shen had told in his heart.

The morning passed quickly, Zhang Hanlin practiced the sword furnace, and the second method of the sword style had been mastered.

After that, Zhang Hanlin did not stop practicing, but continued to practice the sword-holding style and the sword-closing style.

The scorching sun was scorching, the beads of sweat on his forehead slipped down, Zhang Hanlin closed his eyes tightly, and his true qi sank into the dantian, and he did not use a single penny.

The body is as hot as a furnace, the back of the clothes is soaked with sweat, the muscles are extremely sore, and the iron sword in the hand weighs a thousand catties.

Under the pressure of this high wall, Zhang Hanlin made rapid progress, and the sword-holding and sword-closing styles were displayed in a decent manner, and the posture was full.

While Bai Lingxuan on the side was practicing his sword, he was stunned when he watched Zhang Hanlin's rapid progress.

Like yesterday, at noon, Zhang Hanlin and Bai Lingxuan finished their work, Zhang Hanlin went to take a shower again, and then changed into the black clothes that he left in Baifu yesterday.

The black shirt that was changed yesterday, Lingxuan has already washed Zhang Hanlin.

At noon, Zhang Hanlin stayed in Baifu for lunch, and after the meal, Zhang Hanlin secretly asked Bai Shentian what clues he had on the trip to the Heavenly Machine Pavilion.

Bai Shen told him the news he got from Tianji Pavilion.

"Che Chi Hua Sect, Chiba City, Che Chi Clan?" Zhang Hanlin's face was solemn.

"Sister Qin Yue actually has a marriage contract with her!"

"It shouldn't be, how can a big family like the Chechi clan be so unwise to do such a thing. Zhang Hanlin was a little puzzled, the poison of the plague has always been a taboo in the Beichen Empire and even the entire Tian Yuan Continent.

For all clues about the plague, if you don't report it, you will be convicted and sentenced, not to mention the crime of refining the poison of the plague.

It's very unreasonable.

Zhang Hanlin couldn't figure it out, but since Tianji Pavilion helped investigate the clues, the truth would soon be known.

"Uncle Bai, does this matter need to be enlightened?" asked Zhang Hanlin.

"Dongsheng City is located in the extreme east and north of the Beichen Empire, even if you hurry up, it will take ten days to rush to the imperial capital non-stop at the earliest, and there must be no delay in this, it will take more than twenty days to go back and forth, the key is that it is not yet known when the poison of the plague will break out, even if it is the lord of the country, I am afraid it is useless, and who to send is also a problem, and it may be self-defeating, attracting the attention of people in Dongsheng City. Bai Shen's brows furrowed.

"It's a mess of clues, and it's a bit difficult to deal with. Zhang Hanlin deeply agrees.

Zhang Hanlin pondered for a moment and said: "But if you don't report the plague, it's a big crime after all, no matter what, you still send someone to Dianjingyu."

Knowing this matter, we can't control how the lord of the country decides at that time. ”

Bai Shen thought for a while and then said: "It's only like this, I'll think about who to send to Dianjing, it's better to be cautious in this matter." ”

"That's the case, by the way, Uncle Bai, I won't be practicing swords for the time being from tomorrow, I'll study the detoxification formula these days, and then continue to practice swords after this matter is resolved, otherwise I won't be able to concentrate on swordsmanship. ”

"It's fine. ”

Since the afternoon, Zhang Hanlin has not continued to practice the sword furnace by standing on the pile, but has continued to perform three sword moves.

As time passed, Zhang Hanlin became more and more handy with the sword, and the three sword moves were extremely proficient, and the posture became more and more standard.

Zhang Hanlin was silent all afternoon, his mind was full of sword shadows dancing, and his ears were full of the sound of sword blades cutting through the air.

It wasn't until the sunset was sinking and the sky was full of red clouds that Zhang Hanlin reluctantly stopped practicing swords.

In the evening, he did not stay in Baifu to eat, handed over the iron sword to Bai Lingxuan, and then said goodbye and left Baifu.

Bai Lingxuan put the sword in his room, and then rushed to the west hall.

"Senior sister, you're here, the master was just about to ask me to call you and Brother Zhang. Hou Sui said with a smile.

Hou Sui was also helping to set up the tableware, and the work in his hands was non-stop, looking at Bai Lingxuan.

"What about Hanlin?" Bai Shen asked when he saw Zhang Hanlin's figure.

"Dad, Brother Hanlin is in a hurry to go home, and he has already left the house. Bai Lingxuan sat at the dinner table.

Bai Shen knew in his heart that Hanlin must be in a hurry to go home to develop the antidote formula.

Zhang Hanlin hurriedly returned to Zhang's mansion, and Zhang Zhenzhong and Zhang Tianhong had already entered the secret room of the medicine pavilion to start researching.

After casually pulling two mouthfuls of rice and checking his stomach, Zhang Hanlin also came to the secret room of the medicine pavilion.

"Hanlin, you're here, come and study together. ”

Zhang Tianhong did not stop the movements in his hands, took out the poison powder and ink that had been exposed to the sun all day, and gently scraped a little bit with a silver needle and put it on a piece of white paper.

The poison is black-purple in color, with a faint hint of dark red ink, which is very conspicuous on the white paper.

Zhang Hanlin and the three of them carefully observed around the white paper, only a slight breathing sound, and no one spoke first.

There was a faint fragrance in the air, and the three of them had been dealing with medicinal herbs for a long time, and they were very sensitive to all kinds of smells, and for a moment the three of them realized that this was emitted from the poison powder.

It is slightly cool and refreshing to the nose, but then there is a faint feeling of dizziness.

Zhang Hanlin's eyes narrowed slightly: "It's like the smell of broken intestine grass!"

Zhang Zhenzhong and the others nodded and said, "Yes, there are many poisons that can make people dizzy, but this kind of cool aroma can only be possessed by the Broken Intestine Grass." ”

Several people continued to observe, and after two quarters of an hour, there was no new discovery, so Zhang Hanlin said: "The second poison contains a total of nine kinds of poisons, and only then did one be identified, so I can't see it like this."

What's going on, let's just test the medicine. ”

"It's okay, Zhenzhong, go and bring in the three white rabbits that you bought today. Zhang Tianhong asked Zhang Zhenzhong to go outside the secret room, and Zhang Hanlin also followed Zhang Zhenzhong out, and soon the two returned to the secret room with three cages of rabbits.

There are a total of twenty rabbits in the three cages, with white hair and large size, which are domestic rabbits.

Zhang Hanlin also used rabbits for experiments, and drug tests are common, because rabbits reproduce quickly and have a short development period, which can often be bought on the market, so rabbits have become the object of drug tests.

Zhang Hanlin obeyed Zhang Tianhong's instructions and brought a white rabbit from the cage.

"Fetch the water. ”

Zhang Zhenzhong took a medicine bowl and took a cup of water.

Zhang Hanlin held the rabbit's two ears in his left hand and grabbed the rabbit's short legs tightly with his right hand to prevent it from kicking around.

Zhang Tianhong took a silver needle, dipped the tip of the needle lightly into the water, and then gently touched the tip of the needle stained with water in the poison powder on the white paper, and the silver needle was stained with a little poison powder.

The right hand twisted the needle, and with a flick it was pierced on the neck of the white rabbit, and the silver needle continued to tremble when the needle tip was dusted.

The purpose of this is to allow the poison powder to penetrate the bloodstream completely.

Then, Zhang Tianhong pulled out the silver needle and put it aside.

Zhang Hanlin let go of the rabbit and was on the ground, and the three of them watched the rabbit's reaction intently.

At first, the rabbit was still jumping and chirping, but before half an hour had passed, the rabbit lay motionless on the ground, and the hair on his body stood up.

Zhang Hanlin touched his body lightly and was immediately startled, because the rabbit's whole body was cold, his body was stiff, his heartbeat was weak, and he could stop beating at any time. After another half a minute, the one finally lost its breath and fell to the ground.

"The heart is paralyzed, and the heartbeat stops. The blood vessels are closed, the blood is blocked, and the suffocation is dead!" Zhang Hanlin said with a solemn face.

"Only poison dart wood has such terrible toxicity!. Zhang Zhenzhong said, this kind of arrow poison wood grows in the deep mountains and jungles, often guarded by fierce beasts, it is very rare, not only can make poison, but also can be used in medicine, it is extremely precious, it belongs to a kind of poisonous medicine with no price.

Arrow poison wood, there is milky white sap inside, the bark is gray, blooming in spring, to autumn, the sap toxicity reaches the strongest, it is collected and processed, and finally developed into powder, colorless and tasteless, extremely poisonous, because of its efficacy, it is also known as 'seeing blood and sealing the throat'.

The atmosphere was a little silent for a while, the two medicinal herbs that had been recognized now were so rare, and what could the other eight be.

Broken intestine grass, arrow poison wood, these two poisons are famous among the poisons, not only because of their strong toxicity, but also because of their incomparably rare, even in the Zhangjia Medicine Pavilion, the medical saint Zhangjia, who has been inherited for thousands of years, the storage capacity of these two medicinal materials is less than ten copies.
