The pain of losing a loved one had already been experienced by Tang Zixi not long ago. At that time, the Zheng family calculated the Tang family, and the Tang family lost half of the clansmen, and whenever he thought of this incident, Tang Zixi's heart was dripping blood. How could she bear this kind of pain for her best friend?

Therefore, now that he found out that someone was going to harm Yue Feng, Tang Zixi felt that he had to stand up and find out this bad guy!

For the sake of fairness, Yue Feng took out an empty cup again and poured a cup from the teapot. Tang Zixi had not touched these teas, teapots and teacups, which ruled out the possibility that Tang Zixi deliberately manipulated in order to prove that there was a problem with the tea.

Yue Feng held the teacup in the palm of his hand, and the dark luck aura heated the teacup. He is a fire-based physique, and his aura carries the characteristics of fire. Under his heating, the water in the teacup soon began to boil, and soon the water inside evaporated, leaving only a drop.

Yue Feng stood up and walked to the window, a small insect had just flown over the flowers outside the window, and Yue Feng sucked the small insect into his palm with a palm in the air. He used very little force, and the little bug was still alive and unscathed. Yue Feng gently threw the little insect into the cup where there was only one drop of tea left.

Pour it out, and the little bug will die!

Yue Feng's face changed dramatically!

There is really something wrong with this tea! Tang Zixi is not nonsense!

Seeing the results of this test, Ah Shan was also surprised. Still, he tried to keep his composure.

"Tang Zixi, what if there is really a trace of green pine in the tea? A cup of tea condensed into a drop to kill a bug is not at all afraid of humans. Ah Shan defended in a panic.

Yue Feng ignored Ah Shan, but looked at Tang Zixi with complicated eyes. Now, what he wants to know the most, how did Tang Zixi find out?

He is an alchemy master, and he is also the head of the Danshen Sect, and he was manipulated in the tea and didn't know it, if such a thing came out, he would lose face!

Tang Zixi breathed a sigh of relief when he saw that Yue Feng was no longer hostile to him.

Now it's just a preliminary convincing Yue Feng! It's still far from finding out who did it. Moreover, Tang Zixi was more worried about Yue Feng's health than the question of who did the hands and feet.

Tang Zixi asked Yue Feng again: "Master, how long have you been making tea with dew?"

"It's been five years!So what?" Yue Feng's expression was a little flustered.

Tang Zixi listened and said worriedly: "Boss, long-term small intake of green ear pine, accumulated over time, precipitates in the viscera, which will lead to lesions. Do you feel swollen and ulcerated in your lungs now, with a dull pain, and coughing up blood from time to time?"

Yue Feng's face was a little panicked, as soon as Tang Zixi's words came out, he was so frightened that he broke out in a cold sweat, subconsciously reached out and stroked his heart, and looked at Tang Zixi dumbfounded, because Tang Zixi was right again!

His illness is a secret! That is, he suddenly lost consciousness a few days ago, and was discovered by Zhao Yingyan. Only himself and Zhao Yingyan know in the world.

He has never been able to find out the cause of his illness, because he has carefully studied his daily diet and there is no problem, and he is also a person who pays special attention to health.

Since it can't be found, there is only one possibility. That is, when I am old, my physique begins to decline, and my internal organs have lesions.

Yue Feng was worried that his life would be short, and once he passed away, the Danshen Sect would be leaderless. Yue Feng was so urgent, he wanted Zhao Yingyan to get the alchemy master qualification as soon as possible, so that he could pass on the position of head to him.

Now that Tang Zixi smelled the tea he made, he explained his hidden illness in one word, and pointed out that the water in which the tea was made was the root cause of the disease, which was really incredible!

Seeing that Yue Feng's face changed greatly, he subconsciously stroked the position of his heart with his hand, his expression was painful, and the clever Ah Shan immediately understood that Tang Zixi was right again, Yue Feng was really suffering from a strange illness because of long-term tea drinking.

This time, Ah Shan was so frightened that he knelt down with a "poof", and said in a trembling voice: "The head of the house is clear, Ah Shan really didn't do anything in the dew! I swear, if I had done such a thing, the sky would have thundered and the ashes would have been destroyed!"

Yue Feng didn't believe that Ah Shan would do this.

Ah Shan is an orphan he adopted since childhood, although he is usually a bit snobbish, but he is very loyal to himself and has always been cautious in doing things. It is impossible to harm oneself, and it is impossible to let others take advantage of it.

"This is not necessarily what Ah Shan did, maybe there is another mystery. Sir, can you take me to the place where the dew is collected? I will see if I can find any traces of spiders. Tang Zixi said.

"Of course you can. Yue Feng agreed.

Now the person who wants to find out the facts the most is Yue Feng, because he is the one who is sick.

Ah Shan didn't dare to look down on Tang Zixi anymore.

Because the head of the house is really sick, and because of drinking tea with the dew he collected, even if he doesn't harm the head of the house, he can't escape responsibility. Because I wasn't careful enough, I let people take advantage of it!

If Tang Zixi can't find out, his suspicion will be the greatest. If Tang Zixi can prove that the person who harmed the head is not himself, then his responsibility will be lighter......

Ah Shan's fate was in the hands of Tang Zixi, and he could only take Tang Zixi to the back garden of Tianyuan Mansion with sincere fear.

The back garden is full of flowers, there are more plant varieties than the flowers in the front yard, and there is a lotus pond, the lotus leaves are green and green, and the lotus flowers are bright and red. The air here is fresh and pleasant, and the aura is also very strong, the background is green mountains and green waters, red walls and green tiles, it is really a good place for leisure and health.

Ah Shan said: "I don't usually collect dew from any kind of plant, as long as the dew condenses in the morning, I will collect and pack it. ”

Not all plant leaves can condense dew, and some conditions must be met.

There is a waxy presence on the surface of the leaves, so that the water can be collected by the leaves and condensed into water droplets. And condensation requires an attached core, such as particles or dust. Therefore, the dew collected in the natural environment will have impurities, and Ah Shan will only use it to make tea after steaming and filtering it every time.

There is also a situation where some plants can spit out water and release excess water with the tips of the leaves, such as Guanyin and Wannianqing.

Tang Zixi is too lazy to look at the plants that do not meet the requirements, there are more than thousands of varieties of plants here, and it is too time-consuming to check them one by one.

There are many plants that can condense dew, such as lotus, aloe vera, pine and cypress, etc., what makes Tang Zixi care about is the green evergreen.

Tang Zixi walked in front of Wan Nianqing and squatted down to carefully observe the stems, leaves and soil of this plant.

Seeing Tang Zixi observing Wan Nianqing, Ah Shan said: "This Wan Nian Qing's branches and stems are prone to white sticky scale insects, so I regularly ask the gardener of Lihe Garden to come over to help take care of them. But the gardener was fired, and the last time he came here was seven or eight days ago!"

It was that gardener who was fired, and Yunhe had the opportunity to take his place and blend into the Danshen Sect.

Ah Shan said: "The gardener said that he sprayed Wan Nianqing with dripping insects, which can effectively prevent insects, and the concentration of the blend is very low, which is not harmful to people. ”

Tang Zixi said in a calm voice: "I think I already know the principle. ”

Yue Feng asked anxiously, "What did you find?"

Tang Zixi explained: "It is true that a trace amount of Drippium worms is not harmful to people, but the gardener sprayed Driplopodium is at least ten times the normal amount! This thing is not only left in the soil, but also in the roots, leaves and stems, and the accumulated toxins are getting higher and higher over time." When the evergreen spits out the water condensation, the remaining dripping insects will be mixed with the dew. ”

Ah Shan didn't understand even more: "Even so, the tea should be a drop of insects, how can it become a green pine?"

Tang Zixi continued: "Tea is alkaline, and the dropping insects can produce ear green pine that is more than ten times more toxic when exposed to alkali. That is to say, before making tea, there are only dripping insects in the dew, and after making tea, dripping insects will become ear green pine under the action of tea leaves. The concentration of gardener spraying exceeds the standard by ten times, and the evergreen itself has a precipitation and concentration effect, coupled with the habit of cooking and filtering dew, after these steps, the concentration of the dew is already a hundred times the normal amount, and then when the dew with the concentration of 100 times the concentration of the 100 times the 100 times the concentration of the 100 insects in the tea becomes the ear green pine, the toxicity is 1,000 times the normal value. ”

Every word Tang Zixi said, every word made Yue Feng shocked!

"Of course, double the toxicity can only kill a small insect, the insect is fragile and small compared to a human, even if it is a hundred times or a thousand times more toxic, it may not be fatal to a person, not to mention that the head is still a master of the Seven Realms of the Sky Realm. However, after drinking for many years, the toxins will slowly precipitate in the internal organs, and after reaching a certain concentration, the internal organs will be diseased, and eventually fatal. This kind of chronic poisoning is not easy to detect, and once the symptoms appear, the internal organs have been festered, and there is nothing to be done about it. Tang Zixi made a supplementary explanation.

"Master, Ah Shan really doesn't know anything about this...... Ah Shan was so frightened that he knelt down again, and this time he was scared and cried.

"I believe it's not you, the tea I make, sometimes you will drink it with me, if you do it with your hands and feet, you know that it is poisonous, how dare you drink it?" Yue Feng said in a calm voice.

"Uh-huh, the boss is wise!" Ah Shan burst into tears.

"It seems that this is not a coincidence! Someone must be trying to harm me and seek the position of head of the house. This method is really too hidden, too clever! This person is proficient in the way of pharmacology, he is by no means a general, and he is very familiar with my daily life and diet, so he can set up such a big game! If it weren't for Zi Xi's discovery, I'm afraid I would have lost my life in vain......" Yue Feng was angry and sad.

A person who is so familiar with himself must be someone close to him. On the surface, he is friendly to you, but secretly he harms you, there is such a person lurking around him, how can you make Yue Feng feel at ease?

Tang Zixi said: "Master, I think that gardener is the key to finding out the culprit behind it." As long as you get him back for questioning, everything will fall into place. ”

"I think so too. Yue Feng said to Ah Shan: "Ah Shan, don't kneel, you are also involved in this matter, get up!"

"Thank you, sir. Ah Shan stood up in fear.

Yue Feng asked again: "By the way, Ah Shan, just now you said that the gardener was dismissed by Elder Tianshi, do you know what happened?"
