The three of them still shook their heads.

Lin Jinghan was speechless, and finally asked, "Where is Commander Tang?"

Fortunately, this time he finally knew the answer. Shishu breathed a sigh of relief and said:

"Commander Tang came here not long ago and said that if the princess needs anything, she can look for him. He is handling the tasks assigned by the princess, and it is easy to find him outside."

Tang Xun was busy directing his men to investigate the source of the poison. He hadn't noticed Lin Jinghan approaching him yet. It wasn't until the Jingnan Army saluted Lin Jinghan that he turned around and hurriedly said, "Greetings, Princess!"

Lin Jinghan took a quick look and saw a lot of things scattered around the area: food, drinks, and other daily necessities. Most of the military doctors were diligently investigating the source of the poison, so she asked, "Are there any progress in investigating the source of the poison?"

Tang Xun shook his head in shame. "We've checked the food, water, clothing, and utensils, but we haven't found the source of the poison. The number of people poisoned is still increasing..."

"Since the other party dared to poison the Jingnan Army, they must be no ordinary people. It is not unknown whether their poisoning methods are more advanced. Commander Tang does not need to blame himself." Lin Jinghan said solemnly.

"Send a copy of everything the person who was just poisoned has touched to my tent."

"Princess, you can't put yourself in danger!" Tang Xun stopped him without thinking: If the princess was poisoned, his head would not be enough for the prince to chop off!

"If the prince blames me, I will take it all." Lin Jinghan glanced at Tang Xun.

Tang Xun had already seen that Lin Jinghan was a man of her word, so without saying anything more, he ordered his men to move everything to her tent.

After sending everyone away and instructing them not to disturb her rest and making sure that no one could see what was happening in the tent, Lin Jinghan put all her things into the medical space. Thinking that she would know the results in the medical space tomorrow morning, she fell asleep.

I had a good night's sleep. When I woke up again, it was just dawn. There was no sign of Sikong Zhan on the bed. I guess he must have been very busy and didn't sleep all night.

The analysis results of the medical space have come out. What surprised her is that the individual items are not poisonous. The problem lies with the food and armor. They are all contaminated with colorless and odorless drugs. There is basically no fault with this drug, but when people wearing armor eat the food, it will produce toxins!

The other party's poisoning method is so advanced! No wonder they can't find the source of the poison! If it weren't for the medical space, no one would have thought of this!

He quickly dressed and walked out without even bothering to eat breakfast. He went straight to Tang Xun and said, "Take me to the grain camp and the armor camp. Pass the order to all Jingnan troops, suspend breakfast today!"

"Princess, is there a problem with the food supply?" As the saying goes, "The army does not move until the food supply has been dispatched." Food supply is the foundation of the march. If there is a problem with it, it would be a major event! Tang Xun was horrified and did not dare to delay. He quickly led the way.

"We need to see whether there is a problem or not." Lin Jinghan quickly followed Tang Xun and went to the grain camp first.

This inspection revealed that more than 50% of the food and fodder were contaminated with drugs!

"This, this, and the grain in this granary, seal them up immediately and no one is allowed to eat them!" Lin Jinghan pointed out the grains stained with medicine one by one and said,

"Have you used these provisions for breakfast today?"

Tang Xun quickly sent someone to invite the cooks.

The breakfast that had just been prepared was not allowed to be eaten. The cooks were at a loss as to what to do. The kitchen was about to explode. When they heard Commander Tang's question, the cooks stopped cooking and had nothing to do, so they all rushed over.

"Have these grains been used for breakfast today?" Tang Xun asked, pointing to the granaries with problems.

Seeing that someone was sealing the granary, the cooks who had just arrived became even more worried. Upon hearing this, the leader of the cooks quickly stepped forward and said respectfully:

"Reporting to Commander Tang, the army did use some of the corn in their breakfast today. However, the food eaten by the prince, princess, the crown prince, and Doctor Ran was made from grains shipped from the palace, and did not use this grain."

"Today's breakfast is no longer edible. Throw it all away, clean all the kitchen utensils, and make a new breakfast. Thank you for your hard work." Lin Jinghan took out a bottle filled with the disinfectant she had just prepared and handed it to the head cook who responded, saying seriously,

"Remember, add a few drops of this to the water used to wash kitchen utensils. Make sure to rinse them thoroughly, and then rinse them at least three times with clean water before using them. If anyone else in the Jingnan Army is poisoned, you will be held accountable!"

The man nodded repeatedly, took the bottle respectfully, and left with the cooks.

Without stopping for a moment, they went to the Army Armour Camp.

The person who poisoned the soldiers probably wanted to poison more Jingnan soldiers. As a result, 80% of the soldiers' clothes were stained with the drug!

Lin Jinghan rubbed her throbbing eyebrows and pointed out the clothes stained with medicine one by one. "Seal them all. Also..."

She paused for a moment, thinking that it would be inappropriate to just ask everyone to take off their clothes. If Tang Xun wasn't stupid, he would have thought of these things. She changed her words and said:

"It's best not to wear the clothes you're wearing, including the clothes in your hands, until I deal with them."

Worried, he warned again:

"Everyone should have been stained with the drug. Add one-third of water to the wine, stir well, and wipe all over your body. After half an hour, take a shower and change into new clothes."

She glanced at the sky. It was midsummer, and the soldiers were generally in good physical condition, so there was no need to worry about them freezing. Now she needed to deal with the supplies stained with medicine. The medicine couldn't be easily washed off, and she couldn't just throw so much away. Not only would it be wasteful, it would also pollute the air and soil.

Medicines cannot be made out of nothing in the medical space. In addition to energy, it also requires medicinal materials. Previously, she relied on the stock inside to make medicines. Now, to disinfect those materials contaminated with medicines, the medicines needed are not just a little bit. After emptying her stock, there is less than eleven, so she needs to go shopping.

After confirming Sikong Zhan's whereabouts again, she still didn't get a clear answer. She only knew that he had gone out and hadn't returned yet. She took the token he gave her, asked for the fastest horse, and took the Wu brothers and a dozen Jingnan soldiers who hadn't been poisoned. After changing into regular clothes, they galloped towards the nearest town.

Everyone hired carriages and went to various pharmacies in the city to buy the medicinal materials specified by Lin Jinghan. Lin Jinghan went to Huichuntang here alone.

Without any nonsense, she directly revealed her identity to the boss here and asked them to fully cooperate in purchasing medicinal materials. At the same time, she took out the diagrams and medicinal properties of several medicines that she had asked Doctor Ran to help write down earlier.

"If you find any of these medicines that are similar or have the same medicinal properties, please purchase them and send them directly to Huichuntang in the capital and hand them over to the shopkeeper there."
