The dog returned to the camp after cutting down the black tree that day, along with Ding Hai and several members of the detachment who came out, and the black tree was also transported back by Ding Hai and them in a cart. Before leaving, Tie Magnolia was as happy as a child, no wonder, the dog is too young after all, not to mention, the current dog is too important to the garrison.

On the second day after the dog came back, the detachment came across another such tree, this time unlucky, more than 20 people, including Xie Yuanhui, were injured, and another 6 died, this kind of tree is not only 2 meters long, it is the dog that they touched is a small tree. The next day, the black tree encountered by the detachment was more than 40 meters high, the mountains were generally majestic, and the people of the detachment were not scared to death, and the branches hit the people deeply, which was still found early, and the casualties did not expand, and all the arrows of the detachment were shot, and the black tree did not move, but no one dared to approach to cut it, and the whole tree was six to seven meters thick. When I looked at it from a distance the next day, the black tree seemed to be fine. Transform as it is.

There was no way, Tie Yulan and they sent some people back to get arrows and call for reinforcements.

Receiving Tie Yulan's request for help, Feng Zhanyun, Liu Shan rushed over with a biao person, because he brought a gas car, it took a day to arrive, and the 40-meter-high black tree quickly fell under the bombardment of 3 cars.

Since the dog came back, he locked himself in the laboratory and did not come out. A small piece of black tree was intercepted, and the dog put him in a variety of different liquids to observe. The black tree is basically made up of layers of black bark that resembles rubber skin, which is quite elastic.

During this period, Liu Qingshan came once, mainly to see if these black skins were useful, if they were useless, the detachment would bypass these black trees when building roads. It's too much trouble, and besides, the magic crystals captured by the 7th Infantry Brigade are very limited, and they can use a little less. In the past few days, it has consumed almost 3 percent.

Looking at Liu Qingshan's painful face, the dog said seriously, "Things must be useful."

Liu Qingshan asked, "Then do you still cut it?" ”。

"If you can bypass it, go around it first, things grow on the mountain, is it possible that you are still afraid that it will run away?" The dog is a lecturer.

"That's right! How I didn't expect that! Liu Qingshan patted his head, "What! I'll go back first, and there's something else to 、、、," he said, jumping off the table and walking outside like a plague.

"Come back! You haven't played hide and seek with me? The dog reminded angrily.

"Wow" The door to the lab closed, "What! What's the matter? Another day! Sometime! "The voice is getting farther and farther away.

Out of the cave complex, Liu Qingshan breathed a sigh of relief, heh! As luck would have it, I finally managed to run out this time.

"Officer, get out of the ground!" Monta's words have become more and more standard, a look that I know.

Liu Qingshan looked at Monta: "Hmm! Luckily, you say you, Monta, don't you just like to play hide-and-seek? Go and stay with him. ”

“、、、、、、”

Time flies quickly, the dog is studying the black tree every day in addition to practicing, and these days he feels more and more that when he practices the exercises, the vitality is full in the meridians, and there is a sense of satiety. This is a symbol that the Yuan Qi induction has reached Chong Dan, and he is not in a hurry to condense the Dan into a room, firstly, Tie Yulan is not there, and he has not experienced cultivation after all, and he is afraid of taking a fork in the road, so he will ask Tie Yulan in advance about everything. Second, the dog knows that cultivation is such a thing, and the most important thing is to come naturally, and accumulate steadily.

He also probably figured out that when the black tree grows, it secretes a strong acidic substance, that is, the acidic substance will not disappear for a long time after being cut down, and the acidic substance will remain on its surface after the bark is dried in the shade. Soak it in fire brine for a period of time, and this acidic substance will disappear completely.

Layer by layer, the body of the tree resembles rubber skin, which can be peeled off layer by layer, and when unfolded, it is a bit like a black leather cloth, and the elasticity is very high. The dog has done experiments, using this kind of skin to make the bowstring of the bow and arrow, which is much better than the cowhide used by the current garrison, and the half-orc Monta is full with an ordinary bow and arrow, and the effective range of 300 steps can reach 350 steps.

In addition, the dog is very optimistic about the wear resistance of this kind of skin, stabbed with a knife, as long as it is not pulled off, the inch-long mouth will be restored to almost a few breaths, and the air permeability is also very good, with gloves made of it, you can't feel the stuffiness of being wrapped in leather at all.

If the defense ability is good, it is comfortable to use this leather as a set of inner armor. Next, the dog referred to a large number of literature, and some experience of his previous life, and found a breakthrough in a medicine called elm oil, which is a kind of medicine for the treatment of trauma, which has the function of stopping bleeding and building muscle. Chen Danshi in the ambulance team of the garrison had this kind of liquid and borrowed some.

At first, the experiments were not very successful, and one day the dog was so tired that he put elm oil and bark, as well as beige and quilan, and went to sleep. When I woke up, the bark was almost transparent, with a much harder increase but not much less elasticity. Stabbing with a knife is obviously much harder than before to pierce through. This gives the dog a lot of encouragement.

Beibai is a bleach used by dogs to drift the bark of trees, and Kui Lan is a potion used to accelerate the volatilization of acids in combination with fire salts, all of which can be found in the garrison ambulance camp.

Later, no matter how the dog experimented, there was no breakthrough, and the bark eventually became a sheet, so that the people of this world looked at the curious transparent skin, and there was no progress. Just as the dog was about to give up, Ding Hai returned to the Red Mountain camp from the outgoing detachment and brought back a handful of wildflowers, which the dog had also seen and grew next to the black tree. Ding Hai went back to the Red Mountain camp to get supplies, and the bouquet of flowers in Ding Hai's words is, there are no other gifts, send you a bouquet of flowers!

From Ding Hai's mouth, I learned that the current way out detachment has reached the deepest part of the Red Mountain, and sometimes they will encounter large beasts, and once they also encountered a Yuan Beast, and it is a big loss to have the first master of Tie Yulan, otherwise everyone will be miserable. Deep in the Red Mountains is a primeval forest that covers the sky. There are black trees within a radius of 100 meters, as well as running man-eating flowers, snake vines like snakes, which poison you to death without you knowing. Since the last time six people were killed by the black tree, more than 30 people have died in various accidents in the depths of the Red Mountain.

The two talked for a while, and Ding Hai returned to the camp.

After Ding Hai left, the dog held the transparent bark in one hand and the flowers sent by Ding Hai in the other, and the dog sent the flowers to his nose to smell the flowers. This is? The dog feels that the transparent bark in his left hand seems to be moving, although it is not obvious, but it is indeed wriggling, so slow that you can't detect it, but the dog has long been sensitive in terms of neural perception due to daily brain training. Don't talk about others now, it's Tie Yulan, Su Ping, the two top masters of the garrison team can't compare the feeling with the dog.

Su Ping is a physical cultivator, the main practice is the strength and perception of the body, according to the realm, Su Ping should not lose to the iron magnolia. It's even higher, because Su Ping has always been low-key, and the two of them have never fought each other, so on the bright side, Tie Yulan is a well-deserved number one master.

With this feeling, the dog hurriedly put the piece of flower given by Ding Hai on the transparent skin, and the feeling was more obvious, like sea water flowing through the palm, wave by wave. There was a faint fluctuation of Yuan Force in the palm of the hand, although it was very weak.

An idea that passes through a dog's brain like lightning would what would happen if he wore this kind of clothing during his exercises?

Just do it when you think about it, that's a dog. After a while, a transparent underwear was made, a little ugly, the joints were casually worn with straw rope, the size was also large and small, and the neckline was dug with a knife casually.

Wear this ugly underwear on the body, without doing exercises, the dog can feel the faint fluctuation of Yuan Force in the air, a little excited, spit out a breath of turbidity, sit cross-legged, and practice Gong, which is faster than the previous practice, and the exercise runs more smoothly, and the dog knows that this is because of the increase in Yuan Qi perception. The Yuanli light spots in the air began to appear, slowly more and more, like a moth to a fire, disappeared in the transparent skin, and then entered the body, entered the meridians, and the speed of the exercise became faster, the dog had never felt so much Yuan force, so that the dantian was like a rotating Yuan Force transfer station, and the numb feeling slowly turned into heat, a warm feeling, which made people not want to leave, after 72 weeks, the dog forced himself to stop. Looking at the time track, it is nearly half faster than before, it used to take two hours for 72 weeks, but now it is more than one.

The black tree itself is a plant that relies on devouring external nutrients, and its epidermis is a natural tool for devouring yuan power and nutrients, so dogs wear black bark to cultivate, and with the assistance of its devouring function, their own perception of yuan power will increase.

So why does the bark of a wildflower fluctuate when it comes close to the bark, a bit like a scary, and what happens to the bark if you stab it with a knife?

With these questions in mind, the dog launched a series of experiments.

In the case of fluctuating bark, it takes a lot of effort to cut it with a knife or scratch, and if the black bark becomes transparent skin, it will not be able to cut or pierce it with his current strength. The orcs can barely penetrate with all their might, and that's the half-orc Monta! It has a level 3 cultivation of Qi cultivation.

The wildflowers brought back by Ding Hai are, strictly speaking, a flower that inhibits the growth and spread of black trees, and is one of the most common species balance phenomena in nature. Over the course of its long evolution, the black bark has become almost unbelievably sensitive to wildflowers. Once the black bark is close to the wildflower, it will automatically fluctuate, and the dog knows what this fluctuation is because it has no professional equipment and cultivation. But it is certain that this fluctuation will put the black tree in a state of self-preservation.

And the black bark in this protected state will become extremely tough. Due to the limited protection of the black tree itself, it has become tougher, and under a sharp blade like a sword, its protective effect is also minimal. The bleached transparent skin that can be messed up by dogs, under the stimulation of wild flowers, the color will become too white, and the internal tissue will form a substance similar to steel wire, which is not only the black bark itself, because it should be a man-made mutant mixed with black tree, elm oil, beige, kuilan, etc., and the protection ability is quite high.

Soak wild flowers and transparent skin in water, and the transparent skin will become too white in 2 days, and it is difficult to wear the sword, but the elasticity and breathability are very good, and it is much softer than ordinary cloth, and it is transparent. It's just that when cultivating, the effect of devouring the vitality will become minimal.

The branches and leftovers of the black tree were not wasted, and they were used to make a kind of crossbow. The design of the crossbow machine is based on the Turkish short crossbow of the previous life, which is small and lean, and the body lines are smooth.

In order to build a good crossbow body, the dog flipped through the "instrument book" left to him by Shao Shiqiu. Use the crossbow body of the winged man archer as the main material, add some Chinese iron, thunder essence, magic crystal, soft grass, and prepare the materials, and then go to the garrison repair team, and ask the forger Hula to forge a small forge,

The forged crossbow body, black and swarthy, with the different perspectives, seems to have a faint flash of thunder, good elasticity, and the general crossbow machine on the mainland now pursues rigidity too much, because of the black bark and the aiming technology of the previous life, the crossbow body itself has a certain elasticity, and a scale is added to the lookout mountain.

A large part of this crossbow machine is borrowed from the blue horse orc troops, the crossbow guns used by the winged people, and at the same time some mechanical principles of the previous life are also added, which can be fired with one hand, with an effective range of 400 meters, which is more than a little farther than the crossbow used by the winged people, and can fire three arrows at the same time. The size is small, if the Xihai cavalry along the Luohe River in Hongshan are seen now, they must be crying and shouting.

Monta was still a little unsightly when the dog made this kind of crossbow machine, but when he came down with a crossbow, he was reluctant to put it down, with a precise range of 400 meters, the crossbow bolt stayed in the air for a very short time, because the crossbow arrow was short, the shaking in the air could almost be ignored, and even he, a layman with a bow and arrow, now almost began to wonder if he had become a crossbow master in the blink of an eye.

With the experience of Yang Gun and Yang Cannon last time, Gou'er gave the crossbow machine and the inner armor a shorter name.

The crossbow machine is called "Sanhua", the inner armor used for cultivation is called "Devouring", and the inner armor used for defense is called "Protector".

Liu Qingshan played with "Sanhua" for a while, and handed "Sanhua" to the dog as if he was a little reluctant, and said, "Aim and range、、、"

"Everyone within 400 meters can be half a hair," the dog replied proudly.

"Hmm!" Huo Wuxiang, who was leisurely tasting tea, immediately put down the teacup, and "whoosh" turned his head to look at the "three flowers" in the dog's hand.

Liu Shan had the experience of the last time, and quietly distanced himself from Huo Wuxiang a little.

In the military field, an ordinary soldier took over the "three flowers" from the hands of the hair,

A little reluctantly, he handed over the "Sanhua" to the other party, and cautiously prompted, "It's very soft, don't pull it too much!" ”

The soldier nodded, filled three crossbows shorter than arrows, pulled the bolt, looked at the mountain, calmed down, and pulled the trigger.

"Whoosh!"

400 meters away "Smack! "Hit the target.

The soldier looked a little disbelieving, looked surprised, and then picked up the crossbow to look up, down, left, and right、、、

"I don't have flowers, look at what" I didn't like to take the "three flowers" very happily.

The generals of the garrison next to him nodded uncontrollably.

Huo Wuxiang said seriously, "Dog! When is the energy produced! ”

"No iron! There are still a lot of things that are not mass-produced enough,"

"I took this one! Dog! After finishing speaking, he didn't wait for the dog to respond, and took the "three flowers" and left.

"Come back!" Liu Qingshan, Liu Shan, Huo Wuxiang, Su Ping, Feng Zhanyun, almost said in unison.

Fur reluctantly stood still, and looked at the dog with a pleading look.

Liu Qingshan walked over to Zhanmao, stretched out his hand to "Sanhua" and said, "You said you! This is for those soldiers who can't look at the mountain, if you want him to be useless, bring it! ”

"No!" Hair said a little stubbornly, looking at the dog from time to time.

The dog nodded to the dipped fur and said affirmatively, "Give it to him!" I'll get you a better one another day! ”

"Do you hear that? There's a better one another day! Liu Qingshan said with a big grin!

Hair is still reluctant.

Liu Qingshan pointed to the distance of the military exercise ground and said, "Look! Who's that! Suradhi, right? ”

As soon as Mao Mao heard Su Ladi's three words, he put the crossbow machine into Liu Qingshan's hand, "This person, don't talk about it!" ”

"Haha!" Everyone couldn't help but laugh.

In Liu Qingshan's tent, the dog told Liu Qingshan to stab himself with a sword.

"I say! I say! You're not sick! As he spoke, Liu Qingshan also looked at the people in the tent for affirmation.

Taking advantage of Liu Qingshan's inattention, the dog rushed up, and the sword in Liu Qingshan's hand stabbed the dog's chest at once, and the dog's forward force forced the arrow into a semicircle.

Everyone jumped up from the chair in a panic, and saw Liu Qingshan's eyes like a half-orc Monta, the dog proudly patted his small chest, and pouted at Liu Qingshan, that look clearly said that you can't do it!

After understanding the performance of the "Protector", the generals of the garrison dispersed.

Only Su Ping, Liu Qingshan, and the dog were left in the tent, and the dog took out the "devouring".

The current "devouring" is quite beautiful. On the almost transparent material, the dog bleached a faint cloud pattern with beige white, and on the left chest there is a red hill pattern overprinted with sand red. The inner nail is cut according to the proportions of the human body, and the seam is stitched with flowing wire, if you don't look carefully, it seems to be natural, and the stitches of the entire June Fourth are extremely exquisite.

Liu Qingshan dressed in the camp tent to "devour", this is! Yuan Force Fluctuations! Liu Qingshan himself has a level 5 cultivation of martial arts, and of course he knows about Yuan Li. When Liu Qingshan saw the "devouring", he thought it was an inner armor with stronger protective ability, and after wearing it, he felt the yuan force in the air fluctuate, and the inner armor was swallowed up little by little, and then it spread into the skin and meridians.

ran out of the room, squatted down and grabbed the dog's shoulders with both hands, and asked solemnly, "Does anyone else know?" “

The dog shook his head calmly. Then watched Liu Qingshan open his small mouth into an O-shape. Only then did I realize that I was almost naked.

Su Ping next to him also watched Liu Qingshan open his mouth.

Liu Qingshan pointed to the inner armor on his body, lowered his voice, almost lips, and said "divine product" to Su Ping, and then wore the transparent inner armor. Hurriedly ran inside.

God! Isn't the weapon of the god a meta-weapon? How is it possible, Su Ping is a little unconvinced.

Liu Qingshan changed his clothes and walked out of the inner room, looking a little embarrassed, handed the "devouring" to Su Ping, shook his head towards the inner room, and motioned for Su Ping to go to the inner room to try.

Su Ping was also startled when he put on "Devour". He is not only an individual cultivator, but his vitality cultivation is also equivalent to Liu Qingshan, of course, he can feel the effect of the inner armor, and he can't complain that the dog says that the inner armor is called "devouring", which is really appropriate.

This kind of inner armor is nothing to wear all the time, but if you wear it all year round, it will be terrifying. It's horrible. Su Ping is sure that there is no such internal armor in the whole continent, but it is quite rare, and it also exists in the hands of those famous families and hidden masters. If anyone knows that there is this kind of inner armor on Red Mountain now, if they can't keep it, they will recruit those grandmasters and martial idiots. No wonder Liu Qingshan was so nervous.

Su Ping didn't run out naked like Liu Qingshan, changed his clothes, and walked out with the excitement in his heart.

The two of them took turns cautiously instructing the dog for a while. The dog just nodded vigorously and stuffed some rare mountain fruits into his mouth. "Dogs! You can get another one! Suddenly, Liu Qingshan and Su Ping said almost in unison. Yes! The dog responded, saw a rare mountain fruit on the table in the distance, ran away, and climbed onto the table on a chair.

Su Ping and Liu Qingshan were about to say something, but when the dog ran away like this, the words were suffocated back into their stomachs, and then they hurriedly chased after them.

The next day, on the hillside to the west of the camp, the cave complex began to expand, and the garrison repair team was merged into the west hill. The entire West Hill was named "Dream Factory".
