It didn't take long for Siqi to trot back with a large handful of crooked blue vines in her hand, and after warning Xiao Du not to run around, she pushed the door and left.

At this time, Xiao Du and the elves were almost rested, he stood up, stretched his body, and said to the elves: "Rest enough, let's continue training." ”

Hearing Xiao Du's words, the elves did not hesitate at all, and stood up one after another, although Xiao Du did not tell them the reason, but they would still choose to carry it out unconditionally.

Next, except for the mutated vampire vine and the bright tree man, the other elves all accompanied Xiao Du to do push-ups, frog jumps and other actions, while the mutant vampire vine and the light tree man were arranged by Xiao Du to run on the side.

The frogs in the small pond and some of the elves living in the water stared wide-eyed, looking at Xiao Du and the elves around him curiously, wondering why they were jumping around.

When a few grass spirit saw the mutant vampire vine and the bright tree man running, they thought they were playing, and they happily ran after them.

"Let's take a break and drink some water."

After doing a hundred push-ups and a hundred frog jumps, Xiao Du exhaled, sat on the ground, big drops of sweat came out of his body, his sweat at the moment had wet a small piece of land, his thighs and arms were even more sore, seeing that everyone was a little dehydrated, Xiao Du took out water from his backpack and drank it with the elves.

After drinking the water, the electric rat fell to the ground in a large shape to rest, and the other elves were also tired, among them, the four elves were in the best state, such as the Running Bull, the Ice Tiger Golden Lion Beast, the Sealing Demon Stone Giant and the Fire Dinosaur, and they only felt a little prostration, but this is not to blame them, after all, they have never exercised, and they were suddenly asked to do training by Xiao Du, and they were a little uncomfortable for a while.

"You two come back and rest, too." Seeing that the Bright Tree Man and the mutated vampire vine ran back from the periphery of the forest, Xiao Du hurriedly beckoned the two elves to come over and rest, replenishing the water in his body by the way.

"It's not okay to go on like this, overloaded exercise will cause too much burden on the body, and the body's recovery speed can't keep up at all."

After thinking about it, Xiao Du remembered the diluted recovery water he had drunk in the war master class, his eyes lit up, and he stopped practicing next, letting the elves stay to rest, and he ran towards the door.

"Mr. McHallen, do you know how to make reconstituted water?" As soon as Xiao Du opened the door, he saw Mai Harun, who was drinking tea and was deep in thought, and subconsciously asked.

"Oh, reconstituted water? You mean the drinking water that was rationed to the divisional class? McHarlan was stunned for a moment, then came back to his senses and asked.

"yes." Little Du Dao.

"I know, but then again, when did you come here?" McHaren asked with a blank look on his face.

"I've been here for a while, I've been training in the garden." Xiao Du said helplessly.

"It seems that there is such a thing, so don't run around in there." McHaren thought about it, as if Xiao Du had been here before, and warned loudly.

"Don't change the subject, Mr. McHarlan, help me make reconstituted water." Xiao Du said.

"Well, you should recognize some spirit plants, right? Go to the spiritual planting field on the right and pick five restoration grasses, three bitter root leaves, and ten Ganqi flowers. McHallan wanted to refuse, but when he remembered that as a teacher, he didn't seem to have done anything for Xiao Du, so he readily agreed.

"Okay, Mr. McHarlen." Seeing that McHalen agreed, Xiao Du rushed towards the spiritual planting ground with joy.

"This is restoration grass, right? The head is three-leafed, green, with sharp leaves, small spikes, and a whitish trunk. ”

Xiao Du swept the spiritual plants in the spiritual planting field one by one, and finally saw a spiritual plant that was very similar to the book, and stretched out his hand to pull it out.

"Well, the form of sweet potato leaves, the leaves are yellow, the rhizomes are staggered, and the roots are black, this is the bitter root leaf, and its roots are bitter roots."

After taking five restored grasses, Xiao Du quickly found the bitter root leaves and carefully uprooted them.

"Gan Qihua, it doesn't seem to be."

After reading all the spirit plants, Xiao Du still didn't find Gan Qihua, and said suspiciously.

Xiao Du suddenly remembered something, and looked for it along the moist corner, Ganqi flowers like shade, and often clinging to other plants, or between the corners of the wall.

Sure enough, in the corner, after turning over several half-meter-tall spiritual plants that resembled a small fruit tree, Xiao Du found an orange Ganqi flower that resembled a trumpet flower.

"Ni~"

Picking the Ganqi flower from the vine, there was a strange sound at the mouth of its flower, and the flower buds spit out like tongues, Xiao Du looked at it and felt a little curious.

Back in the laboratory, Mai Harlen was still tasting tea, and when he saw that Xiao Du had spent almost ten minutes picking things back, he said dissatisfiedly: "Look at you, didn't you read the book I gave you carefully, and it took nearly ten minutes to confirm that the three spirit plants actually took nearly ten minutes." ”

"Hehe, that Ganqi flower is hiding behind some spirit plants, and I didn't notice it for a while." Xiao Du smiled awkwardly.

"Alright, now I'll teach you how to make reconstituted water."

McHalen walked to the experimental table, and after taking the spiritual plant in Xiao Du's hand, he took five restored grasses and put them in something similar to pounding, and chiseled them with oval stone pillars, while saying to Xiao Du: "The preparation method of recovery water is very simple, the first step is to chisel the restored grass, collect its juice, complete filtration, and collect it in a container, it is not difficult, it is easy to learn." ”

"Hmm." Xiao Du nodded and looked at it very seriously.

A minute later, the five restored grasses were chiseled and sparsely rotten, filling the space for half pounding, and Xiao Du couldn't imagine that after the five reconstituted grasses were chiseled, so much juice would emerge.

"Well, now take a container, cover it with a layer of fine gauze, and pour down the chiseled reconstituted grass liquid, so that after three repetitions, most of the impurities have been filtered out, and now the container is being filled." Mahalen explained step by step, after loading the juice of the restored grass, he took the ascetic roots, and used a knife to cut off the blackened roots one by one, and a strange thing happened, after the roots were cut off, they immediately became dry, as if they had lost their moisture.

"This bitter root is also very easy to handle, after cutting it out, find a container, rub it slowly with your hands, just like this, completely pulverize it, and complete this step."

McHallan gently picked up the dried bitter root, placed it on top of a clean container, and rubbed it back and forth between his hands, and as his hands continued to rub, a fine grain of powder fell into the container like magic, and in a few moments, all three bitter roots turned into powder.

"This bitter root leaf is also a good thing, I told you about it in the book, right?" McHarlan asked tentatively.

"Well, after crushing bitter root leaves and rice, apply it to wounds and burns to heal and heal burns." Xiao Du said.

"Well, that's a good answer." McHaren nodded, continued to take the Ganqi flower and put it on the table, pressed the petals and flipped it, the whole bud spit out, made a Ni sound, was pinched by McHallen, pulled out the heart of the flower together, and laid it out on the table, "This Ganqi flower only takes the heart and bud part, and then as long as these three materials are put together in water and boiled, it will become recovery water." ”

"Isn't that diluted?" Xiao Du asked.

"Huh? That's right, the effect is diluted. McHarlan nodded, then asked, "Are you going to make undiluted reconstituted water?" ”

"yes."

"Well, that's easy, too."

McHallan nodded, took the three ingredients, poured them into a test bottle together, lit the alcohol glass with the blue potion stored on the side, and the blue flame burned, and burned when he hung the test bottle on the blue flame.

"Wait five minutes like this, and the complete rehabilitated water will be completed." McHaren said.

"It's that simple?" Xiao Du asked.

"That's right, it's very simple, if you need it in the future, you can make it yourself, but buy the materials yourself, don't run to pick my spirit plants." McHarlan looked pensive, and muttered: "I don't know what's wrong, there are old spirit plants that haven't been seen in the past two days, and I don't know if they were stolen by elves." ”

“”

Thinking of Senior Sister Siqi who came to pick kiwigrass not long ago, Xiao Du was speechless, and said with a smile: "How could I go and pick your spirit plants, teacher, I'm not that kind of person." ”

"Xiao Du, you are really a good student of the teacher, can you borrow your elves to study for the teacher?" McHaren patted Xiao Du on the shoulder and said hopefully.

"Nope." Xiao Du shook his head.

"Hmph." McHaren snorted and sat down to take a sip of tea.

As time passed, the three materials in the test bottle boiled and gradually merged into one, and the blue flame was automatically extinguished at this time.

"It's done, let's find something to put it on." McHaren spoke up.

"Hmm."

Xiao Du nodded, poured the pale green liquid with a hint of black into the two silver kettles, and thanked McHallen, "Thank you, Mr. McHallen. ”

"Uh-huh." McHallen nodded calmly.

Xiao Du didn't say anything, opened the back door, and returned to the garden.

Restorative water, the potion formed by rejuvenating herb with bitter root and ganqi has the magical effect of quickly recovering from muscle fatigue and activation.
