Chapter 12: The wool is coming in turns

　　 "Yes, the operation is very standard, there is no error. It takes a long time, but it is the first time after all, and it is normal." Chen Wanqing commented.
　　【Glove box proficiency +5%】
　　 At the same time, Xu Qiu also received the system prompt, he secretly calculated:
　　The proficiency has risen so slowly, it seems to be another hard stubble.
　　 But it should be possible to brush up the proficiency quickly by constantly getting in and out of the glove box like brushing tweezers and nitrogen gun proficiency.
　　 But looking for a good time, if you go in and out of the glove box in front of the senior sister, it’s hard to explain.
　　……
　　 "This is almost the content. You should familiarize yourself with the glove box operation first, and I will teach you how to prepare the solution in the glove box later."
　　 After Chen Wanqing finished speaking, she walked to her seat.
　　 has just walked less than halfway, she turned back again, pointed to a cylindrical cabin on the side of the glove box and said:
　　 "I almost forgot to tell you this."
　　"This is the transfer cabin, through which the physical exchange between the box and the outside world can be realized.
　　 Half of the cabin body of the transfer cabin is inside the glove box, and the other half is outside the box. There is a door at the end of the cabin, and a barometer is connected in the cabin to check the pressure in the cabin in real time.
When transferring items from the outside to the glove box, first open the exterior door, put the items in, and then use a vacuum pump to evacuate the compartment to a vacuum state, and then fill it with nitrogen. Repeat the vacuum and nitrogen steps three times to ensure the delivery compartment The inner atmosphere is nitrogen, and then you can open the hatch from the glove box and take out the items.
　　 The same is true for transferring items from the inside to the outside, but when opening the interior door, you must ensure that the atmosphere in the transfer cabin is nitrogen, otherwise if a whole cabin of air is put in, the oxygen level will immediately rise to more than 500ppm.
　　 Teacher Wei pays great attention to the atmosphere in the glove box. He will check every time he comes to the laboratory to see if the water and oxygen index is below 100 ppm.
　　 Now the laboratory is the two of us. If he finds out that the oxygen level has exploded, he will not necessarily treat you well, but I will definitely get scolded. "
　　 "So, you know..." Chen Wanqing deliberately made a very vicious expression.
　　 "Senior sister, don't worry, there is no accident with me." Xu Qiu said confidently.
　　 Then, Xu Qiu put his hand into the glove box again, pretending to be operating, and the light from the corner of his eye glanced in the direction where the senior sister was leaving.
　　 Chen Wanqing returned to her seat and took out a pink water glass from her bag.
　　 She should be going to fetch water, it is a good opportunity.
　　 "Senior sister, can you help me get a glass of water." Xu Qiu said.
　　 Chen Wanqing was stunned for a moment before she realized what Xu Qiu had said.
　　 She gave Xu Qiu a blank look and asked, "Where is your cup?"
　　 "In my bag." Xu Qiu said.
　　 forcibly added a little more work to the elder sister, and he has more time to brush up his proficiency.
　　 At the moment the senior sister left, Xu Qiu acted quickly, concentrated, followed the system image, and began to repeat the "in and out of the glove box" operation.
　　……
　　 About two minutes later, when he heard the footsteps of the senior sister, he stopped.
　　 "I put the water glass in your bag."
　　 "Okay, thank you senior sister."
　　 Then, he started to check the historical improvement of proficiency in the system.
　　【Glove box proficiency +10%】

　　 can add 10% proficiency in the first few times, which is even higher than the 5% in the first operation.
After 　　, the increase in proficiency began to decay, and in the end only 1% remained.
　　He opens the system interface:
　　【Scientific Research Support System】
　　 Permission level: 1
　　 Points: 478
　　 Tasks in progress: 1
　　 Proficiency:
　　【Experimental operation class】
　　Clean the substrate (fourth order 1%/fourth order 50%)
　　【Instrument equipment tools】
　　Ultrasonic cleaner (fourth order 80%/fifth order 0%)
　　 Tweezers (fourth order 9%/fourth order 50%)
　　 Nitrogen gun (fourth order 1%/fourth order 50%)
　　 Glove Box (88% for the first order / 80% for the fourth order)
　　Gas cylinder (first order 0%/fourth order 20%)
　　【Special category】
　　 Literature reading (first-level 72%/fourth-level 50%)
　　 Novice Task IV: Raise the proficiency of any two experimental operations to Tier 4 or above, and reward 500 points for completing the task.
　　##
　　 has been busy for a long time, and the glove box proficiency has only increased to 88% of the first level;
　　 And it actually belongs to the equipment category, not the experimental operation category, so it cannot be used to complete the task.
　　 is a double whammy.
　　 Xu Qiu thought for a while, the latter is not a big problem, because according to the senior sister, he will learn to prepare the solution in the glove box later.
　　 If the "configuration solution" is considered an experimental operation, if you want it to reach the fourth order, the glove box proficiency to reach the fourth order is a necessary condition.
　　 So the key to the problem lies in the former, that is, the increase in proficiency is too slow.
　　 You can’t keep doing experiments secretly while the elder sister is away.
　　 There must be something wrong.
　　 Xu Qiu turned on the auxiliary system and carefully observed a series of actions of the virtual villain.
　　 entered the glove box, picked up a reagent bottle and placed it on the reagent rack, and took a piece of substrate with tweezers,..., then left the glove box, and finally used the transfer cabin to transfer a box of substrates into the box.
　　 In order to efficiently brush his proficiency, he only intercepted the operation of entering and leaving the glove box, and then played it in a loop.
　　 Xu Qiu quickly figured out the reason:
　　 The operation of the glove box is not only about getting in and out of the glove box, UU reading www.uukanshu. com also includes the operation in the box and the use of the transfer cabin.
　　 His proficiency in getting in and out of the glove box is almost full by him, so he can't move.
　　 Wool can't just stare at one sheep. Now the wool of the sheep "in and out of the glove box" is almost bald by him, so he has to find other sheep.
　　 So, in the glove box, he first picked up a pair of long tweezers with his right hand, then grabbed an empty glass bottle, swiped an 8 in the air, and finally put it back in place, then switched to the left hand, and repeated it.
　　【Glove box proficiency +20%】
　　【Tweezers Proficiency +1%】
　　 As expected, it also improved the proficiency of tweezers.
　　 And judging from the increase in proficiency, the weight of the operation in the box should be greater than the weight of entering and leaving the glove box.
After 　　, Xu Qiu changed the target picked by the tweezers from an empty glass bottle to a substrate, using both left and right hands, to move it to various positions in the glove box.
　　……
　　 Soon, the proficiency of the operation in the box is almost full, only 1% increase.
　　 After reaching the fourth-order 20%, the tweezers are not improved every time they are operated, it seems that they have reached the bottleneck.
　　 Xu Qiu left the glove box and began to practice the use of the teleport cabin.
　　【Glove box proficiency +12%】

　　 Chen Wanqing heard the direction of the glove box, and frequently heard the sound of pumping and deflating, and looked at Xu Qiu suspiciously.
　　 Xu Qiu saw this and actively explained: "Sister, I'm practicing using the teleport pod."
　　 "Okay, be careful not to explode." Chen Wanqing said.
　　……
　　 After brushing the experience of the teleportation cabin several times, the proficiency of the glove box finally reached Tier 4.
