Jinchen half-hugged Youzan, and slowly injected the blue liquid into his veins, temporarily suppressing the burning pain that was almost burning his nerves. But this was just a drop in the bucket.The severe pain brought by evolution is like tearing bones apart and reassembling them, and the mental picture is turned upside down, being torn apart by violent forces, forming new, wider and more dangerous mountains and rifts.The mental pain caused You Zan's consciousness to swing wildly on the edge of clarity and chaos."Ugh..."You Zan suddenly hunched up, cold sweat instantly soaked his back, and veins on his forehead throbbing.At this time, Jinchen beside him seemed to be the only antidote that could relieve his pain.You Zan pushed Jinchen, who was sitting on the bed, onto the camp bed, sat astride his waist, held his face roughly with both hands, and kissed him fiercely with a bloody smell and a gasp of pain.His lips and tongue were also violent, as if they wanted to swallow Jinchen's breath, mental strength, and entire person into their stomach in order to fill the endless pain and emptiness.Jinchen leaned back, put his arms around Youzan's violently trembling back, and stroked him gently, responding to this chaotic kiss and relaxing the tense Youzan.We kissed for a long time without any rules.You Zan was breathing rapidly, his eyes still hazy and painful.Jinchen changed his position, put Youzan back on the bed, stroked his sweaty temples, and gently pressed his fingertips on Youzan's shoulder blades."Does it hurt here on your shoulder?"“It hurts…” You Zan uttered the word hoarsely, his body twitching slightly due to the touch.Jinchen's lips immediately fell, pecking and kissing along the taut shoulder line."Here?" Jinchen's palm slid down and covered You Zan's firm belly through the thin fabric.You Zan groaned, his brows knitted, his mental strength raging, "...It hurts too."Jinchen's kiss went from the tight abdominal muscles to the side of the waist.You Zan felt so much pain that he even wanted to grind his teeth. He tilted his head and bit the back of his hand, his trembling eyelashes getting wet.But being kissed by Jinchen like this didn't seem to hurt that much.You Zan's muffled groaning sounded like a whimper of grievance. He turned sideways with difficulty, exposing his back to Jinchen.Jinchen sat up, held Youzan in his arms, and let him lean against his chest.Jinchen slowly pressed along the muscles on both sides of Youzan's spine, while his warm lips fell on his bare neck, the depression between his shoulder blades, and the tight back muscles...Each kiss was accompanied by an infusion of pure and gentle spiritual power, combing through the pain of evolution in his body.Jinchen kissed him in many places, and You Zan fell asleep only after he was exhausted. He curled up in Jinchen's arms like a ferocious beast that finally felt comfortable after being stroked.Jinchen was so angry that he became furious.He looked down at the sentry who was sleeping soundly but still restless in his arms. The lust surging in his eyes was forcibly suppressed, and he gently pinched You Zan's ear.Wait until my wife evolves and then get it back.He carefully adjusted his posture to allow Youzan to sleep more comfortably.-You Zan lay drowsy on the camp bed for three whole days.During these three days, the severe pain brought by evolution repeatedly tortured his body and mind.Every time he had contractions, he became as irritable as a trapped animal, tearing the sheets unconsciously, his mental power dissipating uncontrollably, causing the circle of energy lines to flicker. And Jinchen hardly ever leaves her side.When You Zan lost control and attacked due to severe pain, Jin Chen was always able to control him, and his palms with spiritual power stroked his back and limbs again and again.He personally prepared the medicine, gave injections at regular intervals, and observed the changes in You Zan's body.There were other wounded soldiers in the camp who needed to be treated, and there were also military affairs that needed to be handled.But no sentry dared to raise any objection.On the one hand, Jinchen is an S-level guide and the absolute commander-in-chief, and his orders cannot be questioned.On the other hand... everyone knew that at this moment, no one except Jinchen could get close to You Zan.The unconscious pressure and mental storm belonging to the evolving S-class Sentinel were enough to make the nearby A-class Sentinel feel suffocated and terrified.Only Jinchen can maintain absolute calm in the center of this storm.Everyone is prepared for a long battle.According to common sense, the painful period of evolution from A-level to S-level lasts at least half a month, or even longer.During this period, the sentinels are extremely vulnerable and require the constant protection and guidance of the guide.However, it was beyond everyone's expectation.Just three days later, in the tent where You Zan was housed alone, the violent mental fluctuations subsided quickly like the ebbing tide.On the morning of the fourth day, when the sentry on outer security saw a familiar figure walking out of the tent, he almost thought he was seeing things.You Zan put on a brand new black combat uniform. Although his face was still a little pale, he looked like a tempered cold star, sharp and dangerous.The aura around him has completely changed, and it is now in the absolute domain of an S-class sentinel.Everyone who saw Yuzan, whether sentinels or guides, was filled with shock.Three days, just three days! He completed the terrifying transformation from near-death to S-level!And it seems that there are no sequelae of evolutionary pain!You Zan's eyes wandered around the camp and finally found Jinchen who had just walked out of the command tent.Jinchen was looking down at the tactical board in his hand, and Youzan's heartbeat inexplicably quickened.He took a deep breath, pretended nothing had happened, walked to Jinchen with seemingly casual steps, raised his chin slightly, and made his tone sound calm, with a bit of nonchalant pride."I think... um, I've broken through to S-rank."However, the way You Zan tried to curl up the corners of his mouth completely betrayed his inner joy and pride.Jinchen raised his eyes from the tactical board and his gaze fell on his wife's face, which was full of praise, and a smile instantly appeared in his eyes.He casually handed the tactical board to the adjutant next to him, took a step forward, and held You Zan in his arms."Yeah, I know." Jinchen's low voice sounded in Youzan's ears, with undisguised doting, "My sentinel is really amazing."He rubbed You Zan's short hair which was still a little prickly, and it was much softer than before.You Zan's ears felt hot, but he hugged Jinchen back honestly and buried his face in the crook of his neck.[The villain's heart rate is detected +11, totaling 90! 】After a while, Jin Chen let go of him slightly, looked at You Zan's sparkling eyes, and whispered: "It's just right, I'll take you to meet a friend."
