Gastric juice fell like rain, corroding the ground into potholes.The moment Lin Binbin squatted down, he felt something fly over his head.Suddenly, a chill ran down his spine.A transparent thread brushed past his scalp and deeply embedded itself in the table leg that had been cut off at one corner.Lin Binbin was shocked. He quickly stood up, lifted the tabletop that had lost a leg, and shrank to the side of the white ape.The corrosive gastric juice came fiercely and quickly, leaving him no time to think.It had only been half a minute, but Lin Binbin's heart was as dark as the sky at eight or nine o'clock in the evening, making him truly realize what a death countdown was.He instantly thought of the system's final prompt, "It also has some characteristics of the Soul-Eating Butterfly... So that's it, it seems this is the only way."The more critical the situation, the faster human reactions become.With no way to avoid it, Lin Binbin simply stopped all movements, letting the gastric juice corrode the wooden planks above his head, while he focused all his attention on upgrading.He hadn't used the free points obtained from killing the demon wolf pack before. There were fifty-six points in total, thirty-five of which were all added to the mecha's defense, and the remaining were used to unlock skills.[Do you want to spend 1 free attribute point to learn basic weapons?]"Confirm!"Lin Binbin looked at the remaining 20 points on the panel and decided to use them to draw weapon blueprints.The system rewarded a total of five newbie benefit draws, each costing ten points, which meant he still had two chances now."Zila——" The sound of the mecha being burned near his ear became more and more obvious. Even though the defense had been increased to 75 points, it still couldn't stop the corrosion of the gastric juice.In just a few seconds, the wooden planks above Lin Binbin's head were already full of holes. The white ape simply lay across his head, using its body to block for him.But this was not a long-term solution."Damn it, I can't be this unlucky all the time."Lin Binbin prayed secretly in his heart and directly clicked the draw button.[Ding, congratulations on obtaining the blueprint: Phantom Blade (broken)][It's a good knife, but it's already scrapped. Congratulations on getting another pile of scrap iron.]Lin Binbin: "..."His face turned dark immediately. He didn't expect his luck to be as bad as ever.But now he didn't have time to feel sorry for himself."Continue!"[Drawing... Ding!]Lin Binbin's eyes were a little red, and even his breathing became heavier. If he got another piece of junk this time, his life would really be over."Oh God, I'm willing to exchange three years of my dad's lifespan for a thermal weapon. If not, five years."Perhaps he was really moved by his filial piety, and the system finally responded.Here we go![Congratulations on obtaining the blueprint: Thunderfire Gun (Elementary)][Thunderfire Gun: Can consume energy to spray thunderfire, with great power.][Quality: Purple][Basic attributes: Attack power 70, plus 35 burning bonus][Damn it, you kid got lucky.]It's actually of purple quality!That's a big gain!After feeling happy, Lin Binbin quickly calmed down. He glanced at the crystal cores of the previous black-backed wolf and the demon wolf king, and decisively chose the latter."Let's take a gamble."[Energy inlay successful... High-level energy detected, weapon upgrading, please wait.][Upgrade successful, obtained weapon: Ice Cold Fire Gun (Intermediate)][Attack power +10, speed +5, energy upper limit +2000, quality: Purple][Flame upgraded, releasing cold fire that can only be encountered in extremely cold and yin places. The danger coefficient is extremely high, and anything it touches will turn to ashes in an instant.]It's worth it, Lin Binbin thought, quickly raising the gun.Boom——Flames sprayed out from the muzzle.The moment it just came into contact with the "cold fire", the spirit butterfly was burned into a shadow. Its twisted face slowly disappeared in the flames, letting out painful hisses.The pale white flames tumbled more and more intensely in the confined space. Obviously, it was fire, but Lin Binbin strangely found that the air around him was getting colder and colder."Plop, plop——"He didn't know how long it had been, but the number of spirit butterflies began to decrease rapidly. The moment the last spirit butterfly disappeared, the entire space suddenly heard the sound of a heartbeat.Once, once, piercing the eardrums.It made people feel inexplicably irritable."White ape, go, kill that ghost thing."Lin Binbin handed the gun to the white ape, while he used a dagger to block the threads twining around from all sides.The white ape jumped high, and the flames sprayed on the wings of the Soul-Eating Butterfly. The flames wandered along the veins, and faint clusters of white cold fire could be seen beating on the translucent wings."Squeak, squeak, squeak——"A strange sound suddenly came from above. In the pale white flames, Lin Binbin finally saw the face hidden behind the ceiling.That face twisted its neck in pain, looking so ferocious that it seemed to jump out of its body in the next second and bite the neck of Lin Binbin, the culprit.The acid rain stopped, and the entire space began to shake violently.At this moment, half of the time had passed.The people below stared at the constantly surging white flames without blinking, muttering a few words, "This ugly thing is quite smart. It's been roasted like this, but it still has the perseverance to hide and not move.""I'd like to see if your wings are harder or my thermal weapons are harder.""White ape, shoot at its head!"Although the white ape was already covered with holes all over its body at this moment, its movements became faster and faster. In just a moment, the entire space was covered with pale white flames.The head shrank back again. The Soul-Eating Butterfly, which had been arrogant before, was obviously scared."Good job, white ape. Now let's do the final experiment..."Lin Binbin walked step by step in the flames, walked to the position near the window on the second floor from memory, dipped a dagger in a cluster of fire, and then stabbed it hard into the wing of the spirit butterfly.The originally indestructible wing was now really pierced with a hole. As the wound appeared, green blood actually flowed out.It worked. Lin Binbin was overjoyed. Before he could react, the next second, a gust of hurricane blew towards his position.At the critical moment, the white ape returned and stood in front of him.But even so, the strong wind still hit his face painfully. At this moment, Lin Binbin was also a little glad that the weapon recognized its owner, and the cold fire couldn't cause substantial harm to him."What's going on? Could this Soul-Eating Butterfly have other hidden skills?"The tables and chairs corroded by the acid liquid not far away were all 卷起 by the strong wind and circled in place.In the blink of an eye, the dust and objects rolled up by the wind rotated at high speed, forming a funnel-shaped wind column in the limited space, and then gradually became thicker and larger."Oh my god, a tornado!"Lin Binbin's eyes widened immediately.
